How the wheel (and CAMS) came to be…■ Words & drawings: 1962 CAMS Manual <strong>of</strong> Motor SportOur <strong>Club</strong> is one <strong>of</strong> about 400 affiliatedwith CAMS – the Confederation <strong>of</strong>Australian Motor Sport – the governingbody for motor sport in Australia.<strong>Club</strong> members involved with motor sportare very familiar with the CAMS Manual<strong>of</strong> Motor Sport, which is the annual rulebook CAMS publishes to set out thetechnical regulations governing motor sportin this country.It’s a fairly dry affair.However, recently we came across part <strong>of</strong>the 1962 edition <strong>of</strong> the CAMS Manual(just the fourth edition), which could seethe fun side <strong>of</strong> the sport ...Section 1The Wheel A partly apocryphal account <strong>of</strong> why we are hereAbout 50 centuries ago, in the fertileflood plain between the Euphrates andthe Tigris, a sweating peasant named, itis said, In Jinnah M’Kanik, was pushinga large wicker basket full <strong>of</strong> dates fromnearby palm trees to his humble tent.In Jinnah, like most <strong>of</strong> the human race,was hot, tired and angry. Muttering “theremust be some easier way to do this”, hiseye fell on a section <strong>of</strong> fallen palm log,and it occurred to him that he might beable to roll his basket along using thelog to support the weight and permitforward motion.The idea worked but, <strong>of</strong> course, onlyuntil the log slid out from under theback <strong>of</strong> the basket. His wife, B’aksit Reiva,suggested that he get two logs, and putone under the front as well. Thus the firstfront-end suspension was devised, andthe phrase “easy as falling <strong>of</strong>f a log” firstused.Down at the oasis that night, a few <strong>of</strong>the boys got talking, and one <strong>of</strong> themsuggested tying one log in place underthe basket, to save constantly replacingthe rear one. This In Jinnah did, and theidea worked fine. However, as soon as hegot into s<strong>of</strong>t sand, he found it took fourcamels to move the thing. So he whittledaway some <strong>of</strong> the wood between thesides, and produced a device that lookedsomething like two cones, apex to apex.The design was soon superseded. Jinnah’swife (whose name, B’aksit Reiva, meant“Moonlight over the PalmTrees”, but soon becamecorrupted to “BackseatDriver”) suggested reducingthe weight <strong>of</strong> the assemblyeven more, and Jinnahhacked away with a bronzefragment he’d picked up in ajunk shop in Ur.Not to be outdone, datecarriers all over the districtgot to work on the idea.Every new design, sketched out on ahandy piece <strong>of</strong> papyrus, evoked ironiccries <strong>of</strong> “Here’s another In Jinnah M’Kanik”,so “engineer-mechanic” was eventuallythe general name for these hopefulartisans.Urged on by his growing fame, andfinding onerous <strong>of</strong> the labour <strong>of</strong> carvingaway all the best part <strong>of</strong> the log, InJinnah bethought himself <strong>of</strong> cuttingtwo sections and fitting through thema strong branch, or “ek-sul”, to use theChaldean phrase.So the ek-sul (or axle) came into being,and at last In Jinnah has a workableassembly, which he called “Ka-at”, whichcould be translated as “useful thing”, andpronounced “cart”.The only fly remaining to mar Jinnah’sointment was the screech made as thediscs <strong>of</strong> wood revolved around the “ek-sul”.Dry and gritty, the Ka-at progressed overthe sands to the accompaniment <strong>of</strong> first,a dull “ooo”, then a sort <strong>of</strong> shrill squeak –“eel”.“Ooo-eel, ooo-eel” it went. So B’aksit Reivacalled it a “ooeel”, and thus there came onto the stage <strong>of</strong> human history one <strong>of</strong> themost simple yet far-reaching inventions.Over the centuries <strong>of</strong> conquest and tradethat followed, the “wheel” spread acrossthe known world; by 1600 BC it hadreached Egypt and enabled Pharoah’slegions to dash headlong to their owndestruction at the hands <strong>of</strong> Cecil B deMille in the Red Sea. Possibly the firstgenuine multiple traffic accident dueto excessive speed; it was used by Ben
Hur in the record lap <strong>of</strong> the 1st LatinGP; it carried Caesar and Charlemagne;Boadicea, with a special hub cap,successfully cut her enemies, and evenher own careless pedestrians, down tosize; upon it Marie Antoinette rolledto the guillotine, Napoleon’s guns toMoscow, and the Conestoga wagons toCalifornia and television fame in thelongest reliability trial thitherto recorded.Stephenson’s “Rocket” gave the wheelnew and tremendous significance for,throughout history until his first steamlocomotive, the wheel was still the loadbearingand animal-propelled device ithad been in the desert east <strong>of</strong> Eden.Stephenson made it work for itself. And itwas the enunciation <strong>of</strong> the basic principle<strong>of</strong> internal combustion that followed thediscovery <strong>of</strong> petroleum and the inventivedrive <strong>of</strong> the Industrial Revolution inEurope that opened the door to a new age<strong>of</strong> transport, and allotted to the wheelits functions <strong>of</strong> driving and steering and,later, braking.In 1877, Nikolaus Otto, a Germanengineer, propounded the principle <strong>of</strong> areciprocating internal combustion enginewith four strokes <strong>of</strong> the piston to eachpower propulsion. The “Otto cycle” <strong>of</strong>induction-compression-power-exhaust(or “suck, push, shove, blow” as it mightbe called) is still the basis <strong>of</strong> 90 percent<strong>of</strong> engines, and these all spring fromGottleib Daimler’s adoption <strong>of</strong> the fourstrokeprinciple in his gas engine <strong>of</strong> 1883.Unknown to Daimler, who was a formeremployee <strong>of</strong> Otto’s, another brilliantGerman engineer was also workingtowards the production <strong>of</strong> a self-propelledvehicle, and in 1886 actually produced anauto-tricycle. This Karl Benz, whose namebecame linked with Daimler’s in afteryears both as the title <strong>of</strong> a famous firm... continued27
