Birdcage

Birdcage (pronounced burd-keyj)

(1) A cage for confining birds (built traditionally with wire or wicker and used also as bird cage & bird-cage).

(2) Something that in form (at any scale) resembles (even vaguely) the construction of a birdcage.

(3) In aviation industry slang, the airspace over an airport and the aircraft there in flight.

(4) An area on a racecourse where horses parade before a race (“paddock” preferred in US use).

(5) In US slang, a used-car lot (now rare).

1480–1490: The construct was bird + cage.  Bird was a pre-900 form, from the Middle English byrd, from the Old English bridd & brid (which in the Northumbrian dialect was “bird”) (young bird, chick; feathered, warm-blooded vertebrate animal of the class Aves).  The Old English bird was an unusual collateral form of bridd and originally meant “young bird, nestling” whereas the typical Old English for bird was fugol, related to the noun fowl, of uncertain origin with no known cognates in any other Germanic language (speculated links to umlaut dismissed by etymologists).  Because birds are a creature doubtlessly noticed and in some form named by people since the early days of human evolution, it’s not surprising it believed variants in Middle English may go back to “an ancient period”.  From the early to mid-fourteenth century, “bird” increasingly supplanted “fowl” as the most common term.

Cage dates from 1175–1225 and was from the Middle English cage (and the earlier forms kage & gage), from the Old French cage (prison; retreat, hideout), from the Latin cavea (hollow place, enclosure for animals, coop, hive, stall, dungeon, spectators' seats in a theatre), the construct being cav(us) (hollow) + -ea, the feminine of -eus (the adjectival suffix); a doublet of cadge and related to jail.  The Latin cavea was the source also of the Italian gabbia (basket for fowls, coop).  The noun (box-like receptacle or enclosure, with open spaces, made of wires, reeds etc) typically described the barred-boxes used for confining domesticated birds or wild beasts was the first form and from circa 1300 was used in English to describe “a cage for prisoners, jail, prison, a cell”.  To “rattle someone's cage” is to upset or anger them, based on the reaction from imprisoned creatures (human & animal) to the noise made by shaking their cages.  The noun bird-cage (also birdcage) was in the late fifteenth century formed to describe a "portable enclosure for birds", as distinct from the static cages which came to be called aviaries.  The verb (to confine in a cage, to shut up or confine) dates from the 1570s and was derived from the noun.  The synonyms for the verb include crate, enclosure, jail, pen, coop up, corral, fold, mew, pinfold, pound, confine, enclose, envelop, hem, immure, impound, imprison, incarcerate, restrain & close-in.  Cage is a noun, verb and (occasional) adjective, caged & caging are verbs (used with object) and constructions include cage-less, cage-like, re-cage; the noun plural is cages.  Birdcage is a noun; the noun plural is birdcages.

The term gilded cage (often heard in the form “trapped in a gilded cage” describes a place (or situation) which superficially is attractive but is in some way constraining; a comfortable but confined situation.  The point of the “gilded cage” is the “effective confinement” is achieved not by the “cage” but by the unwillingness of the confined to relinquish the luxury of their “gilded lifestyle”; it’s thus a self-imposed “imprisonment”, certain comfort valued more than the uncertainties of freedom.  The term is thought to have been coined by the writers of the popular song A Bird in a Gilded Cage (1900).  History (some of it recent) is littered with examples of those “trapped in a gilded cage” and overwhelming they’re well-bred women, compelled for various reasons (dynastic, financial, political etc) to marry someone not of their choice.  A classic example of the adage “for everything you do there’s a price to be paid”, the best documented are the most miserable but the phenomenon is an illustration of the way what ultimately matters is not the situation in which one finds oneself but how one reacts.

Consuelo Vanderbilt (1877-1964) was the most illustrious of the American “dollar princesses” who crossed the Atlantic to marry increasingly impoverished members of the British aristocracy.  Unhappily (and tearfully), aged 18, she became Duchess of Marlborough, diligently and dutifully (for a while) fulfilling the role her father’s money had purchased.  The French painter Paul César Helleu was noted for his portraits of society women of the Belle Époque and, working on commission, he was not above flattery but there’s no doubt he captured the beauty of the slender Consuelo and they may have had had an affair, a diversion not uncommon among dollar princesses chaffing against the bars of their gilded cage.  While in the history texts most in gilded cages are there because they led tortured, unhappy lives, there were some who resolved to “make the best of things” and just try to enjoy the gild: taking the rough with the smooth as it were.  F Scott Fitzgerald (1896–1940) in The Great Gatsby (1925) described Daisy Buchanan as a “golden girl” who had opted for the security of marrying money and was thus consigned to life as a “beautiful little fool” in a “gilded cage of class and gender politics.”  There are worse ways to live and as George Bernard Shaw (GBS; 1856-1950) observed, while money may not buy happiness, surely it is better to be miserable and rich than miserable and poor.

The origin of the curious use of “birdcage” to describe the enclosed area where horses are saddled and walked before and after a race lies in an architectural analogy, the space enclosed traditionally by light iron railings, often decorative, painted white and closely spaced.  Spectators standing beyond the perimeter looked at the horses, much as one looks at birds inside an aviary; the metaphor thus “perspectival”.  In truth, the usually the circular or polygonal enclosure didn’t really resemble a large ornamental cage but the construction of the ironwork did recall the sides of a “birdcage” although obviously there was no need exactly to replicate the design, horses being unable, Pegasus-like, to “fly away”.  The term remains in common use in the UK, Australia and New Zealand where it had become part of the “social scene” of race days, the photographs published on society pages or Instagram often taken from “the birdcage”; at some tracks the spectator area has been remodelled for exactly that purpose with appropriate promotional backdrops.  In North America, used of “birdcage” in this context is rare, “paddock” the preferred term.

A similar linguistic adaptation was the “bullpen” (in baseball, an enclosed area for pitchers to practice in or “warm up”), the word possibly borrowed from rodeos where it literally was the (well-fenced) holding area for bulls.  In baseball, “bullpen” became a collective noun for pitchers and functioned as a synecdoche.  From the sport, it spread and came to be used figuratively to describe (1) “a place for someone or something to get prepared for some purpose” and (2) a military prison or its enclosing stockade.  Some decades after bullpen entered the vernacular of the sport, leagues were formed for women’s baseball and although in ranching the term “cowpen” (fenced area for holding cows) was well-known, baseball sensibly decided its nomenclature etymologically was detached from biological sex so assembled female pitchers also warmed-up in a bullpen and despite a recent trend towards gender-neutrality in sporting terminology, “bullpen” survived as fossilized baseball jargon.  Linguistically uncontroversial in the sport was “birdcage mask” which was the protective mask worn by catchers, the “birdcage element” referring to the thick wire structure protecting the face while still permitting adequate vision.

The origin of the use in baseball is contested although all seem to agree it came into use very early in the twentieth century.  One explanation is that by then it had become common for late-coming spectators to be cordoned off in a “standing room” area in “foul territory” (to the sides of the field where any ball hit was deemed “out of bounds”) and, noting the laggards were “herded like cattle”, “bullpen” was borrowed from the rodeo.  When those areas were re-purposed as the pitchers warm-up space, the designation stuck and the notion relief pitchers were once viewed “bullish” in temperament is thought one of baseball’s many myths.  An alternative theory is the use was at least influenced by the outfield fences at baseball grounds once often displaying advertisements for Bull Durham tobacco and in front of these relief pitchers would wait to be called into play and the use was thus associated with the billboards but for this there’s no documentary evidence.

By definition, a birdcage is of course “something in which one keeps one’s pet bird” but they can be also, certainly in their more elaborate forms, a decorative piece of furniture, a symbol of domesticity in the same way George Orwell (1903-1950) in Keep the Aspidistra Flying (1936) used the Aspidistra plant as an identifier of the middle-class though in fairness to the reputation of the perennial herbaceous plant, their popularity in English houses owed much to them being among the species most tolerant of the sometimes smoky atmosphere in an era when coal and wood burned on open fireplaces was a common form of heating.  They were thus an ideal house plant, being tolerant of neglect and suited to shade while their luxuriant growth meant they were effective oxygenators of air high in CO₂.

Tough, the Aspidistra wasn’t exactly “unkillable” but one really had to try and the plants thus were for generations something of a middle class fixture; it was in this sense Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945), in his (sometimes reliable) memoir Erinnerungen (Memories or Reminiscences) and published in English as Inside the Third Reich (1969) noted the birdcage in Adolf Hitler’s (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) country house, some years before it was enlarged in the sprawling complex centred on the Berghof:  “After Berchtesgaden came the steep mountain road full of potholes, until we arrived at Hitler's small, pleasant wooden house on Obersalzberg.  It had a wide overhanging roof and modest interior: a dining room, a small living room, and three bedrooms. The furniture was bogus old-German peasant style and gave the house a comfortable petit-bourgeois look.  A brass canary cage, a cactus, and a rubber plant intensified this impression. There were swastikas on knickknacks and pillows embroidered by admiring women, combined with, say, a rising sun or a vow of ‘eternal loyalty.’  Hitler commented to me with some embarrassment: ‘I know these are not beautiful things, but many of them are presents.  I shouldn't like to part with them.’”  Speer made no mention of a canary or any other bird sitting in the cage and nor is there a reference in contemporary accounts; that is in keeping with Hitler’s known views on how animals should be treated and while his attitudes to humanity proved reprehensible, those on wildlife were quite enlightened.

Although there’s obviously some functional overlap, as well as birdcages, there are birdhouses, coops, aviaries, pigeon lofts.  A birdhouse is a “small house” for birds (and known also as a nest box).  Made usually of wood and mounted somewhere the residents will be protected from ground-dwelling predators, birdhouses are outdoor structures designed not to imprison wild birds but provide them a shelter where they can build nests.  A coop (in this context) is a place where birds are kept but while a birdcage is for a household pet, a coup is for productive (egg-laying and sometimes feathers or meat) birds and are enclosures built outside, partially enclosed (“chicken coops” the best known).  The word aviary has a wide vista and can be anything from a relatively small structure housing two or more birds to vast zoo-like areas in which there may be a mix of captive and wild creatures.  A pigeon loft (known also as a dovecote) is a specialized type of birdhouse, often placed on a building’s roof or other elevated spot in which domestic pigeons are bred and housed, usually for use in the sport of pigeon racing; the element “loft” tends to be used irrespective of the location of the structure.  A synonym was columbarium, from the Latin columbārium, the construct being columb(a) (pigeon) +‎ -ārium (place for) and because the sport became popular among the aristocracy of the Ancien Régime (circa 1500-1789) in France, the construction of columbaria because something of a contest (al la the “size race” in luxury yachts between today’s billionaires) and architects were engaged to design large, elaborate structures, sometimes emulating the style of the owner’s chateau.

C3 Corvette T-Top birdcage.

From its debut in 1953, the Chevrolet Corvette’s body has always been made from non-steel composite materials ranging from simple GRP (glass-reinforced plastic and better known as fiberglass) to materials of increasing complexity so rust has never afflicted the external panels but beneath all those curves and angels is much vulnerable including the frame and “birdcage”, that latter an object of veneration or despair, depending on its condition.  A crucial component in the overall strength and structure of a Corvette, the birdcage was first integrated into the design when the C2 (1962-1967) was released and the same concept was used for the C3 (1968-1982): a reinforced frame surrounding the cabin, the nickname from the overall shape which vaguely recalled a birdcage.  Similar in outline to the “safety cell” for which Mercedes-Benz was in 1952 granted Patent 854157 (rigid passenger cell with front and rear crumple zones), the birdcage consisted of boxed steel channels with pillars running from the base of the windshield (A-pillars), along the rear of the cabin, and down to the frame kick-up behind the seats.  Although not really a complex piece of engineering, the fact that so integral to the car is the structure, for extensive repairs to be performed considerable disassembly is required and the cost of out-sourcing such a task often can exceed the value of the car; economics thus suggest it’s usually advisable to find a car with birdcage in sound condition, repairs often financially viable only if the car is rare (ie with a highly desirable specification or even a celebrity association).  A visual inspection is best left to experts because unless it has just emerged from a comprehensive restoration, all C2 & C3 Corvettes will have at least some light, surface rust but it can take an expert eye to tell the difference between that and rot which demands attention.  Fortunately, the Corvette community is vibrant with publications and on-line guides detailing the features & foibles of the birdcage.

On both the C2 & C3, there were two variants of the design, one for the coupe (T-top in the C3) and the one for the roadster (the last such C3 made in 1975) but all shared the susceptibility to rust, especially if used in areas with high salt-exposure (coastal regions or places where the stuff was spread on icy roads) and the part most often affected severely was the “Windshield Frame Lower Outer Corners”, replacement sections available and in two different versions for the C3, reflecting the design changes in the post 1973 cars.  However, while the birdcage's most afflicted components, the windshield frame’s outer corners are not unique and the hinge pillars & lock pillars (including the body mount at the bottom) also are notably rust-prone.

The C4’s (1984-1996) “birdcage” was a bit of a gray area because although routines still is used, materially and structurally it was quite different from the classic template set by the C2 & C3.  What was carried over was welded steel structure surrounding the windshield frame, A-pillars, roof rails, B-pillars and rear window frame which created a defined passenger safety cell distinct from the outer composite body panels so it seems reasonable still to use the term but the C4 did not have a “stand-alone” frame onto which the body was mounted, the “birdcage” being an integral part of the frame.  There were a number of design imperatives which dictated the path chosen for the C4 and it was built with a uniframe in which front and rear frame sections were integrated, thereby providing greater rigidity so no longer was the “birdcage” a kind of bolted-on” internal scaffold but an inherent part of the whole.  The C4 was the last Corvette in which something recognizably “birdcagesque” would appear.

Chevrolet’s technical rendering of the C8’s structure.  In engineering, materials science and computing, much has advanced since 1962.

However, the structural integrity the birdcage in 1962 provided needed still to be achieved but the “brute-force” approach of the C2-C3-C4 era was replaced with more advanced techniques and by the time the mid-engined C8 was released in 2019, the platform structurally would have been unrecognizable to anyone familiar with the earlier generations.  The C8 is built around a core element (the so-called “backbone” or “spine”) which can be visualized as a large aluminum tunnel running down the centre of the car and from this the chassis gains its primary torsional stiffness.  The body panels are almost all non-structural and while there is (as is now universal) a reinforced “safety cell” around the cabin, this is protection of occupants in the event of an “impact incident” (better known as a “crash”).

The Birdcage: The Maserati Tipo 60/61 (chassis #2549, clothed & exposed).

Upon released in late 1962, the structure in the C2 Corvette gained the nickname “birdcage” because of the shape but before that, there was the Maserati “Birdcage”, the Tipo 60/61 (1959-1961) so dubbed because it departed from the typical approach of those building space fames in that instead of relatively few, thick tubes and sections, Maserati used many more but they were slender.  Observers were much taken with the apparent delicacy of the construction and although the engineers assured all the intricate latticework of some 200 chromoly steel tubes (welded often in triangulated form in the points of highest stress) was a design delivering both lightness and rigidity to match the more robust-looking creations.  Those admiring the intricacy were struck more by the resemblance to the thin wires of birdcages.  

Mercedes-Benz 300 SLR (W196S, upper) & 300 SL (W198, lower).

One of the reasons the Maserati’s skeleton looked so delicate was that the space-frame had become associated with Teutonic-flavored construction like that used by Mercedes-Benz for its 300 SL & 300 SLR.  Both shared the same method of construction but despite the names and the visual similarity between the two, there were few common components beyond the nuts, bolts & screws.  The 300 SL (W198; 1954-1963) was a road car while the SLR (W196S; 1955) was a lengthened version of the W196R Formula One Grand Prix car with a sexy body and an enlarged (though somewhat detuned) straight-eight engine; in the sport, it would be the last of the straight-8s.

The final and most remarkable Maserati birdcage was Tipo 63 Birdcage which featured a mid-mounted 3.0 litre V12.  The Tipo 60 & 61 used front-mounted four-cylinder engines in displacements of 2.0 & 2.9 litres and although there were problems which never wholly were solved (although the reliability did over time improved), the platform enjoyed some success because its forgiving nature lent it excellent handling characteristics and in long-distance events, the lack of power was somewhat offset by the modest fuel consumption and relative low tyre wear, time not spent in the pits as valuable as seconds shaved off lap-times.  Unlike some of its competitors, Maserati did not have the financial resources to “keep up with the times” and develop from scratch a mid-engined sports car so the factory took the approach familiar to many an American engineer and hot-rodder: put in a bigger engine.

1961 Maserati Birdcage Typo 63.  Although installing the V12 didn’t realize the hope-for success, the car will always have a place in the annals of “great moments in exhaust systems”.

Actually, the V12 wasn’t that much bigger than the largest of the four cylinder units used but, with a pedigree beginning with a brief (though unsuccessful) career in the Maserati 250F Grand Prix car, it certainly delivered more power.  Because it was a “relatively” simple matter of blending an existing engine and existing platform, the project quickly was accomplished and Maserati had a mid-engined car on the grid before anyone else and one which could top 305 km/h (190 mph) on long straights.  Unfortunately, placing the big lump of a V12 to the rear upset the Birdcages’s fine balance although one did place fourth in the 1961 Le Mans 24 Hours endurance classic (a place where a 190 mph top speed was unusually valuable), a result which proved to be the marque’s high-water mark in the famous event.

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.

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”.  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.

1959 Ford Fairlane Galaxie 500 Sunliner with suicide knob (on steering wheel at 10 o'clock).

“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.”

A young lady wrapping practiced fingers around the timber shift knob in 1970 Maserati Indy (Tipo 116, 1969-1975).  In the era, it was fashionable in Italian exotica for the knob and steering wheel rim to match (ie in leather or wood).

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 Nadar (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 told 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 for the two-speed Powerglide automatic transmission in 1953 Chevrolet Corvette (left) and a classic spherical shift knob in 1972 Chevrolet Corvette LT1.  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 in the 1964 300K.

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.
