Tuft

Tuft (pronounced tuhft)

(1) A bunch or cluster of small, usually soft and flexible parts, as feathers or hairs, attached or fixed closely together at the base and loose at the upper ends.

(2) A cluster of short, fluffy threads, used to decorate cloth, as for a bedspread, robe, bath mat, or window curtain.

(3) A cluster of cut threads, used as a decorative finish attached to the tying or holding threads of mattresses, quilts, upholstery, etc.

(4) To furnish or decorate with a tuft or tufts; to arrange in a tuft or tufts.

(5) In the upholstery trade, to draw together (a cushion or the like) by passing a thread through at regular intervals, the depressions thus produced being usually ornamented with tufts or buttons.  Tufts are not merely decorative because they secure and strengthen mattresses, quilts, cushions etc; they act to hinder the movement of the stuffing.

(6) In botany, a small clump of trees or bushes.

(7) A gold tassel on the cap once worn by titled undergraduates at English universities, one of the more blatant class identifiers if the UK’s class system; the word tuft was also applied to those entitled to wear such as tassel and from this use evolved the slang "toff".

1350-1400: From the Middle English toft & tofte (bunch of soft and flexible things fixed at the base with the upper ends loose), an alteration of earlier tuffe (which endures in the Modern English tuff), from the Old French touffe, tuffe, toffe & tofe (tuft of hair (and source of the modern French touffe)), from the Late Latin tufa (a crest on a helmet (also found in Late Greek toupha) and probably of Germanic origin (the Old High German was zopf and the Old Norse was toppr (tuft, summit).  The earlier European forms were the Old English þūf (tuft), the Old Norse þúfa (mound), the Swedish tuva (tussock; grassy hillock), from the Proto-Germanic þūbǭ (tube) & þūbaz.  It was akin to the Latin tūber (hump, swelling) and the Ancient Greek τῡ́φη (tū́phē) (cattail (used to stuff beds)).  The excrescent t (as in against) was an English addition and tuft was used as a verb from the 1530s.  In some contexts, bunch, cluster, collection, cowlick, group, knot, plumage, ruff, shock, topknot & tussock can impart a similar meaning but tuft is better for its specific purpose.  Tuft & tufting are nouns & verbs, tufted is a verb & adjective, tufter is a noun, tuftier & tuftiest are adjectives, tufty is a noun & adjective and tuftily is an adverb; the noun plural is tufts.

The 1550s noun tuffet (little tuft) was from the Old French touffel (the diminutive suffix -et replacing the French -el) which was a diminutive of touffe.  In English the word is obsolete except for the use in the nursery rhyme Little Miss Muffet which seems first to have appeared in print in 1805 although it (and variations) may have been circulating much earlier.  Etymologists believe Little Miss Muffet’s tuffet was a grassy hillock or a small knoll in the ground (a variant spelling of an obsolete meaning of tuft).  The latter-day use to refer to a hassock or footstool is an example of how (usually obscure) words can acquire meanings if erroneous definitions are often repeated and come to serve some purpose.  Tuffet for example became a favorite of antique dealers who are apt to call both footstools and low seats “tuffets”, a handy practice perhaps when provenance is doubtful.

Little Miss Muffet
Sat on a tuffet,
Eating her curds and whey;
There came a big spider,
Who sat down beside her
And frightened Miss Muffet away.

Those whose fear of spiders (and other arachnids, such as scorpions and ticks) is so severe as to adversely affect normal life are said to be arachnophobic.  Although one of the most commonly described anxiety disorders, in the current edition (DSM-5-TR) of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM), arachnophobia is not a diagnostic category but is classified as a sub-type of Specific Phobia, Animal Type, a clinical diagnosis typically described as “Specific Phobia, Animal Type (spiders)”.  The DSM’s criteria for a specific phobia include (1) marked fear or anxiety about a specific object or situation, (2) immediate fear response on exposure, (3) active avoidance or intense distress, (4) fear disproportionate to the actual danger, (5) persistence (typically 6+ months) and (6) and clinically significant impairment or distress.  So, one who merely is not fond of spiders would not meet the DSM’s criteria; the fear must be severe enough to impair functioning or cause substantial distress over at least six months.  The irony is that as well as most spiders being small, non-venomous and not at all anxious to attack humans, co-existing with them and their webs in most cases will improve quality of life by culling the insect population.  For those not convinced, arachnophobia can be treated by a number of therapies including (1) systematic desensitization (a gradual exposure to the source of the distress), (2) the adoption of “calming techniques” which can lower the distress response and (3) CBT (cognitive behaviour therapy), a structured, goal-oriented form of psychotherapy focusing on identifying and changing negative or dysfunctional thought patterns and behaviours.  The estimates vary but all research indicates well under 10% of the global population suffer arachnophobia to the extent a clinician would diagnose with women being significantly more affected.

Critics of interior design tend not to approve of padded or tufted headboards and the shinier or more pillowy the effect, the greater will be the disparagement.  Such critics probably tend to prefer a minimalist aesthetic and condemn anything which doesn’t conform as outdated, excessive or just in poor taste but that aside, there are practical reasons to avoid the padding because the material can over time collect dust, dirt, and oils, something of concern to allergy sufferers.  The designs can also provide hiding places for the dreaded bed bugs.  Still, there are some who like the “generic luxury hotel room” look and argue they’re a kind of safety feature, banging one’s head on some tufted padding a less troubling event than an impact with one of Ikea’s hard, flat surfaces.  Like any bed, there are advantages and drawbacks, some thing made more comfortable, some close to impossible.

Nobleman in full dress at Cambridge (1815) with golden tuft.

The noun toff began as mid nineteenth century lower-class London slang for "a stylish dresser, a man of the smart set".  It was an alteration of tuft, which was a mid-eighteenth century English university (Oxford & Cambridge) term for students who were members of the aristocracy, a reference to the gold ornamental tassel (or tufts) worn on the academic caps (mortarboards) of undergraduates.  Throughout the “long eighteenth century” (a historian’s term which refers for the epoch running from the Glorious Revolution of 1688 to the Congress of Vienna in 1815 (the “long nineteenth” being 1815-1914 and the “long twentieth” 1914-2001 (ie 9/11))), undergraduates at both Oxford and Cambridge were differentiated into four classes: (1) noblemen, (2) gentlemen, (3) commoner-scholars (fellow-commoners at Cambridge) & (4) servitors (sometimes known at Cambridge as sizars and at Oxford as battelers).  Each of these classes of undergraduates was entitled to a different form of dress, noblemen since 1490 (further clarified in 1576) entitled to wear silk and brocaded gowns of bright colors. Such rich materials emphasized noble status, as did the costly dyes. The gowns had flap collars, Tudor bag sleeves with gold lace decorations (akin to the black lace decorations used today on Oxford gimp gowns) and a velvet round cap with a gold tassel (or tuft) was worn.  Noblemen were technically (if misleadingly) nobiles minorum gentium and included the sons of bishops, knights and baronets and, by resolution of Convocation, could include heirs of esquires.

The right to wear the golden tuft was briefly restricted to those with fathers entitled to sit in the House of Lords while those less blue-blooded were allowed only to a plain black tassel but things gradually became less exclusive until the practice was abandoned in the late nineteenth century but the transfer of sense was inevitable: wearers of golden tufts came to be known as tufts.  Those toadies or sycophants (and there were many) who were slavish followers of the tufts were tufthunters and their antics, tufthunting, such individuals and their habits quite identifiable to this day.  By the 1850s, under the influence of the cockney accent, the word had been transformed into toff (some dictionaries of slang noting toft co-existed in the 1850s but this may have been a mishearing) which endures to refer to anyone rich and powerful although the original sense was of someone apparently well-bred.

1912 Stutz Bear Cat (1912-1934); after 1913 they would be dubbed Bearcat (left) and 1915 Rolls-Royce Silver Ghost (Chassis 2BD, 40/50; 1906-1926) limousine by H.A. Hamshaw (right).

One of the fastest and most admired American cars of the early era, the Stutz Bearcat assumed such a place in popular culture, it was was claimed that should anyone die (except by suicide) at the wheel of a Stutz Bearcat, they were granted an obituary in the New York Times (NYT).  Wholly apocryphal, the origin of the romantic myth is thought to be related to the Bearcat being a symbol of wealth, adventure, and daring, owned by the sort of chaps (such a lifestyle at the time was most associated with men although women adventurers were not unknown) who would likely anyway warrant an NYT obituary.  The Bear Cat's tufted leather upholstery was typical (though not universal) of the high priced automobiles of the time although already, elaborate fabrics were appearing in vehicles with enclosed passenger compartments which afforded protection from the elements.  The appointments of 1915 Rolls-Royce Silver Ghost were opulent even by the coachbuilding standards of the day (the Edwardian traditions still maintained) but the chauffeur's compartment lacked a roof (the body style really a Sedanca de Ville as were many of the early English "limousines") so was still trimmed in tufted leather.  The more sheltered passengers enjoyed carved ivory door handles, beveled glass windows, cut crystal lamps, an inlaid wood folding table, two jump seats, and door pockets, communications to the chauffeur via a tubular intercom.  The lavish upholstery in the rear was tufted, beige West-of-England cloth with embroidered silk window pulls and trim-work, including rear compartment shades and sliding divider although what usually attracts most comment is the elegant, pleated, cloth rosette headliner with its cloudlike billows.   To make journeys more pleasant, a set of leather-wrapped flasks was mounted in the right rear armrest.

1908 Hotchkiss 16-20 hp Type T Roi des Belges (King of the Belgians) Touring Car with tufted red leather (right) and 1917 Packard Twin Six Touring Car with channel tufted black leather (left).  The term “touring car” was never exactly defined and use varied between UK & US manufacturers but typically it described a large, four-door, 4-6 seat open car, supplied with a folding top and (usually optional) temporary side curtains.  The style went extinct but did fork into the phaeton (no top or side-windows) and the four-door cabriolet (or convertible) (a folding top and retractable side windows).  However, even by the 1930s, the old coachwork terms from the days of horse-drawn vehicles had come to be used with such imprecision the descriptions were sometimes little more than vaguely indicative and in the post-war years they meant whatever manufacturers at the time wanted them to mean.

In the matter of upholstery, the word “tufted” has long been synonymous with “deep buttoned” but in the early days of the automobile. Coach-builders and upholsters would offer the option of “channel tufted” trim which essentially was “tufting without the buttons” although it seems almost always to have been executed only with parallel seams (ie nothing on the diagonal).  Probably because what would now be understood as a “pleated” style was more comfortable for sitting on in a moving object, it became popular in the 1920s.  Of course, what the machinists called the “straight tuck-roll” technique was less labour intensive and used smaller quantities of materials so interiors could be trimmed at lower cost so the incentive was there to make the switch.  The revival of button-tufting in the late twentieth century was not an exercise in mere nostalgia but an expression of conspicuous consumption, the “obviously expensive” look making tufting in the big US cars something of a Veblen good.   

1972 Oldsmobile Ninety Eight Regency advertising.

Tufted leather upholstery was common in early automobiles, the seating often exactly the same as those used in horse-drawn carriages, houses or commercial buildings (and certainly gentlemen's clubs).  The practice faded as production volumes increased and as early as the late 1920s was coming to be restricted to only the most expensive models.  This exclusivity tended to prevail until 1972 when Oldsmobile introduced the Regency option for its full-sized Ninety-Eight (sometimes as "98") models, a package, the visual highlight of which was tufted "loose-pillow" velour upholstery (although unlike the use in furniture where the "pillows" were detachable for cleaning, in the Ninety-Eight they were fixed permanently to the seats.  Suddenly, solidly middle-class Oldsmobile (right in the middle of General Motors’ (GM) five-step (Chevrolet-Pontiac-Oldsmobile-Buick-Cadillac) hierarchy; the so-called "Slone ladder" designed to both facilitate and encourage "upward automotive mobility" conceived by Alfred P Sloan (1875–1966;  president of General Motors (GM) 1923-1937 and Chairman of the Board 1937-1946)) had brought both velour and loose-pillow seating to the masses.  The velour was at the time admired by most buyers (though derided by some critics of design) and as tufted upholstery began to proliferate in the industry it was usually offered as a cheaper alternative to leather.  In some climates the velour was probably the better choice and was welcomingly comfortable although in some of the more strident shades of red could recall the popular idea of how a bordello might be furnished.  Presumably, those who'd never enjoyed a visit to a bordello were more disconcerted than regular customers.

1974 Imperial LeBaron four-door hardtop (left) in chestnut tufted leather though not actually “rich Corinthian leather” which was (mostly) exclusive to the Cordoba (1975-1983) until late 1975 when not only did the Imperial's brochures mention "genuine Corinthian leather (available at extra cost)" but for the first time since 1954 the range was referred to as the "Chrysler Imperial", a harbinger the brand was about to be retired.  Imperial's advertising copy noted of the brochure photograph above: “...while the passenger restraint system with starter interlock is not shown, it is standard on all Imperials.”; the marketing types didn't like seat-belts messing up their photos, reminding people cars sometimes crash.  While all of the big three (GM, Ford & Chrysler) had tufted interiors in some lines, it was Chrysler which displayed the most commitment to the motif.

1977 Chrysler (Australia) Valiant Regal SE.

In the era, Chrysler's Australian outpost did cut a few corners when implementing the “pillowed look”, economies achieved by (1) using fewer buttons for the tufting of the fabric or optional leather and (2) attaching the tufted “feature sections” directly to the cushion squab rather than creating an emulated “pillowed” look which appeared to sit atop the structure.  Even by the time of the release of the CL range (1976-1978) the feeling was the writing was on the wall for the once popular Australian Valiant (1962-1981) and the top-of-the-line Regal SE was created in the time-honored Q&D (quick & dirty) way by including all the less Regal’s options as standard equipment; only the tufted upholstery and optional leather was unique to the model.  Sales were modest but there remained devoted following for the Valiant which was durable enough to endure the sometimes harsh environment and it was highly regarded for its towing capabilities, equipped either with the lusty locally-developed 265 cubic inch (4.3 litre) straight-6 or the imported 318 cubic inch (5.2 litre) V8.  Built on the US A-body platform, when production ended in 1981 it had lasted a half-decade longer than the Plymouth and Dodge versions sold in the home market and only in Mexico would use continue until 1988.

1974 Cadillac Fleetwood Talisman.

Oldsmobile's move was as audacious and influential as Ford’s introduction in 1965 of the up-market LTD which, like the Regency package, had the effect of cannibalizing sales from other divisions within the same corporation.  Cadillac, although with a range priced considerably above Oldsmobile, offered nothing with such an ostentatious interior though when it did in 1974 respond with its Talisman package (1974-1976), it made sure it did so with more tufted extravagance still, in 1974 offering leather as well as velour.  The trend the Regency package started would last over twenty years and is remembered especially for the tufted fittings used in Imperials, Chryslers and Dodges, the hides used in the Cordoba range (1975-1983) said to be "rich Corinthian leather", an advertising agency creation which meant nothing in particular but sounded vaguely European and therefore expensive.

Color choice made a big difference to the perception of the "tufted look", more subdued hues like green and blue less confronting than the "bordello red" which became emblematic of the industry's phase.  Cadillac called the fabric in the Fleetwood Talisman "Medici crushed velour" which had about the same relationship to historic truth as "fine Corinthian leather" but the package sold well over the three seasons it was offered, despite the option costing almost as much (and the leather significantly more) as some new cars.  Among collectors, the holy grail is a 1974 Fleetwood Talisman trimmed in blue leather; although it was on the option list, none has ever been sighted and the factory's records don't breakdown production between the blue and the alternative "medium saddle" (a medium tan), some of which have been verified.

1350–1400: From the Middle English knobe & knobbe, thought almost certainly from a Scandinavian or German source and probably at least influenced by the Middle Low German knubbe & knobbe (knob; knot in wood; bud), the Middle Dutch knobbe & cnoppe, the Dutch knop (knob, button, bud), the Old Frisian knopp & knapp, the Old High German knopf (bud, pommel of a sword, knot, loop), the Middle High German knospe, the German Knopf (button, knob) & Knospe (bud), the Danish knap (button) & knop (knob, button, bud) and the Old Norse knyfill (short horn).  Most etymologists seem most convinced by it being a variant of the Proto-Germanic knappô (knob, lump) & knuppô (lump, clod), both among the “kn-” words related to knudaną (to knead).  Probably related were the Middle English knap & knappe (small projection, knob (in the sense of “button, tassel, tuft etc”), hill, hilltop etc)), from the Old English cnæp & cnæpp (summit, top), which may in some way be linked with the Old Norse knappr (small projection, knob (in the sense of “button, head of a stick etc”)) (and from which English gained knop), the source again the Proto-Germanic knappô.  The meaning “knoll, isolated round hill” seems first to have appeared in the 1640s and, perhaps surprisingly, no instance of “doorknob” has been found prior to 1829 although the word may have been long in oral use (drawer-knob, window-knob etc all followed).  Knob is a noun & verb, knobless is a noun, knobbed & knobbing are verbs, knoblike & knobby are adjectives; the noun plural is knobs.

In idiomatic use, the phrase “same to you with knobs (sometimes “brass knobs”) means “the same to you but even more so” (used typically in response to an insult or slight).  A “knob-twiddler” can be an informal term for a technician or console operator whose job entails adjusting electronic devices via knobs but it can also describe anyone whose role seems either unimportant or not particularly demanding.  As machinery and later electronics became an increasingly ubiquitous part of life, so did knobs and as early as the late nineteenth century the humorous “knobologist” had been coined to describe both those designing the system and the “knob-twiddlers” using them; the discipline of design was of course dubbed “knobology” and that remains a core component of ergonomics, exploring imperatives such as placement, size, tactility and labelling, all of which influence the functionality of controls on an instrument as relevant to their application.  The knobologists deeply were implicated in convenient physical switches, knobs and buttons disappearing from cars and re-imagined virtualizations on inconvenient touch-screens.  Such has been the reaction (including the realization the change made driving more accident prone) that the tactile controls are making a welcome comeback.  The now archaic “knob-thatcher” was an affectionate term for a maker of wigs while the more modern “surfer's knob” was slang from the sport, describing a hard bump or nodule on a surfer's knee, shin or ankle, resulting from recurrent contact with their surfboard.  In engineering and metallurgy, “to knobble” was (1) to render a surface with a knobbly finish and (2) to produce wrought iron by treating semi-refined puddled iron on a hearth before shingling, a specialized device in the business being the ominous sounding “knobbling furnace”.

Gay men supporting lesbians at the first “Dyke March”, Washington DC, April 1993.  The sign held by the protester at the far left uses the compound word for which the euphemisms “knob polisher” & “knob-gobbler” were coined.

Because knob was popular slang for penis, a number of derived terms predictably emerged.  A “knob polisher” or “knob-gobbler” was “one who gives fellatio”.  “Knob rot” was a reference to certain sexually transmitted diseases contracted by men, the acute condition “galloping knob rot” describing a rapidly progressing or uncontrollable variant of the condition.  A “knob job” was the act of fellatio.  “Knob cheese” (the terms “cock cheese”, “dick cheese” and (in context) even “cheese”) was vulgar slang for smegma (a whitish sebaceous secretion that collects between the glans penis and foreskin or in the vulva).  “Knob jockey” must however be used with care because it has variously been applied to (1) gay men, (2) promiscuous straight women and (3) promiscuous straight men; context thus matters.

Although a sight to delight button-nerds, "peak button" unfortunately coincided with the "biodegradable wiring incident" (1991-1995) in which the soy-based insulation for the cables deteriorated some decades before the supplier's projected end-of-life, the issue exacerbated by the taste of soy which would attract rodents and other creatures happy to chew on the stuff for a quick snack.  The basic shape of the gear selector knob dates from one introduced in 1971 in the 350 SL (R107, 1971-1989), the design a product of analysing data from the Swedish government's mandatory post mortems (autopsies) of road-accident fatalities (under Swedish law, such corpses were for 48 hours the property of the state).  What the pathologists' findings revealed was lives could be saved if engineers could devise as a shift lever handle too large to penetrate the eye socket.  While there's an element of the macabre in such research and it wasn't something the factory choose widely to publicize, the design was a classic example of what's called "passive safety".

Interior of Porsche 917K with cool (in both senses of the word) balsa wood shift knob.  The obviously "fake" passenger bucket seat was installed to comply with the rules in sports car racing.

To this day, the myth persists the balsa wood gear-shift knob used in the Porsche 917 was there as a “weight-saving measure”.  While it’s true the small knob was light, the difference between it and the aluminum or magnesium units the company had fitted to earlier race cars would have been so insignificant it’s doubtful it would have equalled a gulp of coffee the driver may or may not have enjoyed.  The stylish timber piece was however not a decorative flourish but a legitimate engineering solution to ameliorate one manifestation of “chronic heat soak”.  In 1969, the 917 was a radical advance which, Dreadnought-like, rendered all other cars in its class instantly obsolescent but the flat-12 engine (Porsche’s first in the configuration) radiated so much heat it was difficult to manage.  In a tradition it would not for decades abandon, Porsche continued to use air-cooling for the engine (which really means “oil cooled” about as much) and it ran hot; between that heat source and the gear level was a unbroken metal path, each component a most efficient conductor.  During endurance racing (some events conducted over 24 hours), cockpit temperatures could reach what doctors would rate as “extreme”.

Close-up of balsa wood gear-shift knob in Porsche 917K.

The metal lever was just one of the sources of this heat and the knob (which sat next to the driver’s knee) needed to be grasped by the driver, often many times a minute; were it to become so hot it caused pain, it would have been safety issue.  Although in 1969 the space-age was at its zenith, the materials which could have made a driver’s gloves close to heat-proof were not then commercially available so they gained much of their protective quality from thickness but the problem was they could be only so thick because a driver needed still to handle a highly-geared steering wheel and operate the many knobs and switches within arm’s reach.  Balsa wood, with its very low thermal conductivity was ideal because while not exactly cool to the touch after a few hours on the track, it never got so hot it felt unpleasant.  It also had adequate strength for its task; a gear-lever knob does not bear structural loads and, being Porsche, it received the same careful attention as every other component, each one precisely machined to exact dimensions before receiving two coats of clear lacquer.  Most variants of the 917 used the balsa wood part although when (as the “Turbo-panzers”) the most powerful of the breed appeared in the Can-Am (for Group 7, unlimited displacement sports cars) a metal knob was fitted, made possible because Group 7 was for open cars and significantly that reduced cabin temperatures.  By the late 1970s when the space age had made available materials (phenolic plastics, composites etc) with superior insulation qualities, the need to resort to a balsa wood knob vanished but the visual appeal remained and in the aftermarket, 917-style knobs remain widely available.

2006 Spyker C8 Laviolette Widebody: Dashboard layout with four-spoke “propeller” steering wheel (left) and toggle switches with nerf-bars (right).  While screens may for certain purposes be better than knobs & switches, the latter often are easier to use and visually, can be most pleasing.

What Porsche did in designing the linkages to the transaxle was dictated by nothing other than usual the design imperatives for racing cars: robustness, reliability, ease of operation and lightness, the use of balsawood as an “anti heat-soak” material wholly in accord and the same parameters were applied by Spyker when designing their distinctive shift mechanism.  Spyker, a boutique operation from the Netherlands, began operation in 1999, the name coming from a Dutch coach-builder that between 1880-1926 would branch out from horse-drawn carriages to automobiles and even aircraft.  Since 2000, between various local difficulties (including bouts of bankruptcy), Spyker has produced a number of high-performance models and while the mechanical specification has always been impressive, what has also drawn attention are the exquisitely finished interiors, the attention to detail (typified by the nerf-bars used to make lawful the use of toggle switches) a delight for those who study such things.  Unfortunately the four-spoke “propeller” steering wheel (a style last seen in volume on the Jaguar XK150 (1957-1961) was eventually judged just too potentially lethal to be granted an exemption from compliance and was replaced with something more accommodating from the Lamborghini parts-bin.

While Spyker’s wonderfully crafted shift mechanism for the rear-mounted ZF transaxle with exposed shafts of stainless steel might seem an affectation, it’s pure functionalism; being a direct mechanical linkage, they provide precise gear-shifting, always a challenge with such a layout (the Porsche 914 (1969-1976) community coined “broomstick in a jar of mayonnaise” to describe the to describe the experience of the earlier "tail-shift" models, the post 1972 "side-shift" build a great improvement from "bad" the "satisfactory").  Spyker’s engineering is thorough and although pure-steel from transaxle to knob, heat-soak along the shaft is said to be minor so there was no need to resort to timber for the knob.

1959 Ford Fairlane Galaxie 500 Sunliner with suicide knob (on steering wheel at 10 o'clock).  This was a generation before "softer, gentler steering wheels".

“Suicide knob” was the most popular name for the device attached to a vehicle’s steering wheel which facilitated easier “single arm steering”.  The idea dated from the days before the almost universal fitting of power-steering and the things became popular in the US in the US in the 1950s and 1960s as even low-priced cars became heavier; for some drivers, they were invaluable when manoeuvring at low speed, especially when reversing.  They were known also as the “necker knob”, “wheel spinner” and “granny knob” but the most correct term was “Brodie Knob”, the name in honor of Steve Brodie (1861–1901), an apparently rather raffish gentleman from New York City who, as a last resort in 1886 after losing everything gambling, staged a stunt in which he jumped off the Brooklyn Bridge (site of a good many suicides), the lure a sum of money he was bet although the details of that are murky.  Mr Brodie anyway survived to collect on the wager and, on the basis of the notoriety gained, began performing other dare-devil acts for even more money.  So the jump from the Brooklyn Bridge was a good career move although the consensus now is it was a cunning stunt (ie a scam), a weighted dummy the real diver with Mr Brodie entering the water from the safety of the shoreline.  In fairness, at least some of his subsequent dangerous stunts were verified by observation and he parlayed his fame into a successful career in business, becoming a noted philanthropist and dying a rich man.

The invention of the suicide knob generally is credited to Joel Thorp of Wisconsin but similar devices had for centuries been in use on land and water.  What Mr Thorpe described in the supporting documents for what was issued as US Patent 2,101,519 STEERING WHEEL SPINNER KNOB (Dec 7, 1937) was an “improvement” of the concept:

“The present invention relates generally to improvements in appliances for facilitating manipulation of the steering wheels of vehicles, and relates more specifically to improvements in the construction and operation of spinner knob attachments co-operable with the peripheral rims of steering wheels or the like in order to effect more convenient and rapid operation of such wheels under certain conditions of use.  Generally defined, an object of my present invention is to provide an improved steering wheel spinner knob which is simple in construction and highly efficient in use.”

Although widely used on tractors, heavy transport vehicles and such, it was in the 1950s as cars in the US became heavier the suicide knobs gained popularity and some of that was due to reasons Mr Thorp probably never envisaged.  One receptive market was males aged 17-25 (a crew infamous for many reasons) who found the combination of suicide knob and bench seat made an idea ecosystem, enabling one hand to be used steer the vehicle while the "free" arm could wrap around the girlfriend (or alternative) who affectionately was resting her head on the driver’s shoulder.  In this arrangement, a driver’s attention more easily could be divided between her and the road.  It was also males aged 17-25 who were the core of the hot-rod community which began as a West Coast phenomenon (induced by a critical mass of the right demographic, available disposable income and a good supply of cheap, used cars which easily could be modified as desired) and they found suicide knobs the best way to “do a half donut” (a spin of one’s hot rod through 180^o), the trick being to grip the knob and then suddenly turn the wheel while applying full throttle, resulting in a loud, spectacular maneuver, made the more pleasing for the driver by him having “left his mark” in strips of runner on the road.  This, the hot rodders called “spinning a brodie”, a variant on the earlier “doing a Brodie” (a dangerous or otherwise inadvisable act) which entered the language after the nation-wide publicity which followed Mr Brodie’s alleged leap from the Brooklyn Bridge.  In the era, a Brodie Knob was as essential a piece of equipment as one’s packet of unfiltered Camel cigarettes or pair of fluffy dice hanging from the rear-view mirror.

1962 Maserati 3500 GTi.  Some Maserati 3500 GTs (Tipo 101, 1957-1964) had the unusual feature of having front and rear quarter-vents fitted to the same door; they were opened and closed using knurled, stainless steel knobs.

The dark appellation “suicide knob” was bestowed because (1) the devices came to be associated with accident-prone drivers (the “males aged 17-25” cohort prominent in the statistics) who probably did use the things to engage in “risk-taking” and (2) by virtue of their location (by default affixed to the upper quadrant) on the wheel, they were a genuine danger in accidents and, in an era of non-collapsible steering columns, tales of them penetrating the eye socket, causing irreparable loss of vision and traumatic brain injury, were legion.  The crusading US lawyer Ralph Nader (b 1934) is criticized for much but the contribution his book Unsafe at Any Speed (1965) made to reducing the death toll on the roads cannot be under-estimated and the effect was world-wide because the rest the industry eventually followed the lead of the US legislation which came in the book’s wake.  In the US and elsewhere, change was of course resisted but it came and while it’s not possible to estimate how many deaths and often gruesome injuries the reforms prevented, no one denies it’s a big number.  The suicide knob was one minor casualty of the movement and in road-registered vehicles, in most jurisdictions (although some US states remain permissive), such devices are permitted only for specialized (often low-speed) vehicles and if used by drivers with some disability which precludes the use of conventional controls.

Another to make a life-saving contribution to reducing the road toll was George Hurst (1927-1986; founder of his eponymous company) whose great legacy to humanity was the “Jaws of Life”, a hydraulic cutter he first developed in 1961 after being shocked at how long it sometimes took to extract the driver from the crumpled wreck of a race car.  The great advantage of the “Jaws of Life” was that it worked like a very powerful pair of scissors, avoiding the showers of sparks produced by mechanical saws, always a risk to use in areas where fuel is likely to have been spilled.  The basic design came to be used in hydraulic rescue devices worldwide and quite how many lives have been saved by virtue of its use isn’t known but again, it would be a big number.

Two decades of progress: Shifter knob for the two-speed Powerglide automatic transmission in 1953 Chevrolet Corvette (left) and a classic spherical shift knob in 1972 Chevrolet Corvette LT1 (available only with a 4-speed manual transmission).  The delicate-looking shifter in the 1953 Corvette seems modest but the location was a world-first for an automatic and was efficient because the location (between the driver’s seat and transmission tunnel) provided the shortest possible path to the linkage; as late as 1964, Chrysler used a similar apparatus for the handful of 1964 300Ks fitted with a manual transmission.  One amusing geometric quirk is the three-dimensional sphere and two dimensional circle share the same definition: A shape in which all points are equally distant from the centre. 

However, before the Jaws of Life, Hurst was already famous in the vibrant sub-culture which was at the times also known for its propensity to purchase and install suicide knobs.  Hurst produced “shifters” which were the assemblies connected to a transmission, used by the driver to “change gears” and they proved instantly popular which may seem strange given every manufacturer at the time included a shifter with every vehicle.  However, beginning in the late 1930s, the US manufacturers had begun moving from centrally located, floor-mounted levers to units on the steering column because it made for better packaging efficiency in the cabins, then optimized for bench-seats with three-astride seating.  That move achieved the goal but with the linkage between lever and gear-changing mechanism now longer and making more turns, some precision in the shifting was lost and column shifting (the once almost universal “three on the tree”) was less conducive to an enthusiastic driving style (such as that of the “suicide knob equipped” crowd).  It was in the 1950s the taste for floor-shifts like those in European sports cars began to gain critical mass and even though the 1953 Chevrolet Corvette was hardly a sports car in the tradition of MGs, Fiats and such, it’s notable Chevrolet from the start installed a floor shift for the (two-speed!) Powerglide automatic transmission; it may not have been a sports car with a “four-on-the-floor” but it had a floor-shift so there was that.  Automatic transmissions in mass-produced cars was then something of a novelty barely a decade old and the Corvette’s floor shift was apparently a world-first.

Four-speed manual transmissions began to appear in Detroit-made cars in the late 1950s and within half a decade George Hurst’s shifters were close to obligatory for any racer (authorized or not) seeking “street cred” and it wasn’t a confected image, the Hurst shifters demonstratively superior without being excessively expensive.  So stellar did their reputation become even GM (General Motors) relaxed their long-standing ban on other brand-names being associated with their products and made a feature of one being standard equipment of the 1964 Pontiac GTO, the car credited with being “the first muscle car” and such was the success in 1965 the shifter’s handle was even permitted to be embossed: HURST.  Soon, other manufacturers actively were seeking co-productions.  George Hurst’s path to market domination was shockingly simple and might have come from a textbook: (1) a perfected design, (2) skilful engineering in development, (3) high quality in production and (4) an attractive price, a combination of elements with great appeal for buyers and manufacturers alike.

Hurst’s dual-gate automatic transmission “His and Hers” shifter with conventional apparatus “for the automatic minded little lady” and a performance-oriented configuration offering manual control for the “man who really wanted a 4-speed standard stick but bought this extra just for her.”  Note the unfamiliar shift pattern, the now universal PRNDL not an industry standard until 1965, the year before it was demanded by regulations.  From the early days of automatic transmissions in the 1940s, reverse had been directly adjacent to Low, allowing drivers more easily to emulate what was done with manual transmissions when a “rocking” was being induced to try to free a vehicle from mud or snow.  It was a quirk of the age and, because reliability was not then what decades later came to be expected, the early transmissions included a second (rear) fluid pump to permit push/tow/hill starts.  Probably, not many much dwelt on the shape of the knob Hurst put atop the His and Hers” shifter but in geometry it would be described as an oblate spheroid with two parallel planar truncations.  Now easily modelled in software rendered with a 3D printer, perfecting a shape like this for production used to absorb much time on the drawing board and in the creation of prototypes.  A spheroid is an ellipsoid generated by rotating an ellipse about one of its principal axes which, if “stretched” along one axis becomes a prolate spheroid (ie elongated and something like a rugby ball).  If slightly flattened along the axis of rotation, it’s an oblate spheroid (like planet Earth which isn’t quite a pure sphere) but the His & Hers knob, having a slight elongation along the shifter’s axis, is closest to a prolate spheroid.  The planar-truncation (ie sliced by two parallel planes) created the (left & right) flat faces and the knob can thus be described as a “truncated ellipsoid” or “truncated prolate spheroid” but anyone wishing to out-nerd the rest would probably coin something like “biaxial ellipsoid with parallel planar truncations”.

It was early in the era of second-wave feminism (1960s-1980s) that George Hurst made his brief foray into marriage guidance counselling.  First-wave feminism (1895-1950s) is sometimes called the “de jure” or “structural” period because the focus was on legal issues such as women's suffrage, property rights and political candidacy but, in the West, an early victory was overcoming any opposition to women being granted driver’s licences.  Attitudes however evolved not wholly in parallel with legal rights and even today, among some, the view persists it’s men who are focused on performance and speed while women value vehicles using other criteria.  Impressionistically, that stereotype is not wholly without foundation but, since second wave feminism reset the rules, it’s no longer possible to run advertising perpetuating the notion.  The “His and Hers” shifter worked with a key-lock which enabled the husband to ensure only he could use the “manual override” feature and the idea in recent decades has been revived although this time the target of the lockout includes one’s (presumably male) children and any concierge or attendant who might be entrusted with parking one’s car.

The magic of Hurst’s shifters was in the mechanism but, just as for computer users the mouse and keyboard assume great importance because it’s by touching these relatively simple pieces of hardware that use can be made of the machine’s more sophisticated internals, it was the shifter’s knob which was a driver’s most intimate connection with the transmission.  Although in the art deco era there had been some lovely detailing, it wasn’t until the 1960s most conceptually moved beyond beyond “variations on a theme of sphere” and Hurst was among the manufacturers to explore shapes and substances.  There were “T-Handles” (which, usually as "T-Bars", were for decades popular around the world for automatics) and “Horseshoes” which attracted admiring glances but didn’t catch on and any number of novelty items including billiard balls (the “8 ball” predictably a favourite of the V8 crowd) and scale models of this and that including human body parts such as the skull and mammary gland.  Knobs could be of plastic, wood or various metals and came in designer colors, velvet coatings a nice touch of the 1960s.  The most fetishized of the muscle car era however was Hurst’s “Pistol Grip Shifter” which did what it said on the tin: it gave the user the feeling of holding a handgun.  In the 1960s, gun culture in the US hadn’t yet become what it is today (as now defined, the first “mass-shooting” didn’t happen until 1966) but it was still a place with a lot of firearms.  However, despite the potential implications, when in 1970 Chrysler made one standard equipment on the 1970 Plymouth ‘Cuda, one brochure made mention of the device only with the bland: “...a convenient pistol grip”.  For a corporation which called the Cuda’s hood scoop the I.Q.E.C.A.G. (Incredible Quivering Exposed Cold Air Grabber), it seemed a missed opportunity though it didn’t have much linguistic luck with I.Q.E.C.A.G., customers and everybody else deciding it was a “shaker”.

Architecturally, the choice between specifying door levers or door knobs is often one of mere preference or aesthetic conformity but for public or commercial buildings, some regulatory authorities now mandate the use of levers because typically they are easier to use for those with disabilities (especially if hand-mobility is limited) as they demand less dexterity.  Additionally, being circular and often highly polished, knobs can be hard to use with wet hands so that’s a consideration in kitchens, bathrooms and such; nor do young children find them as convenient as a handle.  So, all that would seem to make a compelling case for the handle but for domestic use, there’s one quirky consideration some may wish to include when making the choice.  While there are verified cases of cats and dogs learning to open doors using a handle, no pet has yet been observed mastering the turning of a door knob; while a rare problem, the chance of one’s cat or dog opening door using a lever is not zero and, because houses tend to use the same style of lever throughout, once they have learned to open one door, they’ve really learned to open all.  If it’s a concern, the good news is most doors are adaptable for either so replacing a lever with a knob does not usually require the door being replaced.
