Show THE MILEAMINITE WHEEL S > u c I A dispatch from London of recent date I says A bicycle has just been completed here which promises to revolutionize the wheels of the world The difference between be-tween this and the older machines Is that it ultilizes the entire power furnished by I the engine of propulsionthe leg of the rider For years bicycle manufacturers have sought some method whereby the waste of power could be prevented but Gerald Barker has found I The change is of course in the Hearing Hear-ing but it is not a chalnless wheel that sort which it is said will next year be the king of all wheels I the opinions of experts ex-perts are worth anything the Barker compound com-pound crank wheel is the one that will i take precedence over all There are three reasons why this new invention claims attention at-tention The first is that it is far speedier the second Is that the propelling power Is almost doubled without Increase of exertion I exer-tion and the third is that on a racing wheel the compound crank will be such again II a-gain as it Is hard to imagine It Is asserted that by the use of the compound crank a cyclist Is enabled to use at least 40 per cent higher geaHng without increasing the stroke of the pedals ped-als or the pressure on them The machines ma-chines that are built especially for ladles may have their cranks shortened and the I distance between the pedals considerably I reduced Instead of using a higher gearing gear-ing A 28Inch driving wheel is geared to ICO inches by the ordinary pattern chain running over a 23toothed sprocket wheel and a 7toothed hub ring The sun and planet wheels merely control the relative position of the main and secondary cranks The mechanism consists of a sun wheel rigidly I and concentrically attached ttt to each side on the crank bracket and a i pair of hollow cranks I Onehalf of each crank incloses a sun t wheel and the outer half Incloses a planet I wheel of the same size a the sun wheel and engaging directly therewith Each pedal Is screwed Into a planet wheel at a point midway between Its center and the pitch line of its teeth Each crank has half the spindle attached to it This spin TiI rir fi t die Is hollow u Jt as each half Is cut to I the same skew and they are brought together I to-gether In a bearing sleeve ty means of a hollow tie bolt provided with a conical lock nut the two halves form a wellsup I ported scarfed spindle Keys and coters are dispensed With and an unusually wide crank bracket bearing Is provided the I ball races being more than four and one I half Inches apart The chain line Is brought within the bearings while the overhang of cranks and pedals Is considerably consid-erably reduced The planet wheel bearings each consist of a single ball race of about four and onehalf Inches In diameter and the pedal pin makes Its circuit within this ball race All the bearings are cup adjusting and are provided with simple and efficient looking devices On roadster machines dust caps are fitted to the inner faces of the cranks so that the sun and planet wheels are entirely cased in Should i become necessary to remove the pedals casings cranks or planet wheels the nuts ami screws are easily acceptable The foot motion Is but slightly I different from the circular motion now In vogue and Is bv no means unpleasant These compound cranks add somewhat to the weight of a bIcycle but the Inventor claims that the power gained more than compensates for the added weight This ingenious mechanism is about to be fitted to a number of racing machines and the interest results of the trial will be awaited with Inteest In saying that he believes his invention will revolutionize wheeling Mr Barker knows what he is talking about I his I crank will really do all that Is claimed and ultilze the entire leg power of the I rider there would seem no possible rea son why a cyclist should not attain a I speed of a mile a minute without any tremendous tre-mendous exertion The influence that this I will have exerton the arofesslonal bicycle I st 8s 1 1 racing world is simply tremendous It Is J considered more than likely for Instance I that I the compound crank achieves a thorough success some genius If not Its torough j I inventor will plan out a scheme to make n11e 1 r It chainless The chalnless bicycle Is the wheel of I 1SOS I Is speedier less costly In the long run and more durable Now combine with this the utilization of the entire leg power of a rider and It seems to most persons who understand the bicycle that a i possibility is created which Is almost al-most limitless I means In other words lmitess that a machine is in sight which will last i a tremendous length of time be so strong i as to be almost without danger of injury In-jury except through collision and be capable ca-pable of a degree of speed which oiw a short time ago seemed among the impossibilities I im-possibilities i This Is why England tithe is so 1 thoroughly and completely Interested in the new invention and it is not too much to say that it will not be the fault of the Englishmen I an American mind gets j ahead of theirs in perfecting the combination combina-tion referred to ton Another point which Is being considered I Is that the chalnless wheel and the compound com-pound crank wheel ought to be combined and sold at not over SCO It must be understood I un-derstood that In judging prices of bicycles on this side of the water we figure on a I different basis of calculation In the first place the English and the French wheels I are very much cheaper than those made I In the United States using I United States prices as a standard of comparison The I very best bicycle made In England can be purchased for 6 and most persons consider I con-sider that exorbitant I is a fact that the I wheel which has been selling In America for 0 has been put upon the market here at S60 To be sure it has not the I same plate but I personally know the statement made to be true |
