SUPPORT FOR BICYCLE'S.

SPECIFICATION forming part of Letters Patent No. 634,480, dated October 10, 1899.

Application filed November 15, 1898: Serial No. 696,494. (Nomodeld To all whom, nil/Jay concern:

Be it known that I, CARL SOHREIBER, a subject of the King of Prussia, German Emperor, residing in Breslau, Prussia, Germany, have invented certain new and useful Improvements in Rests or Supports for Bicycles and other Vehicles, of which the following is a specification.

The present invention relates to a mechanism for cycles and similar vehicles which enables the rider while seated upon the saddle.

to come at any time to a full stop in the middle of the road and to proceed without alighting from the wheel. Besides it is possible easily to mount on and to dismount from the cycle when supported by the said mechanism. The latter consists of two supporting-rods which are arranged on both sides of the cycle, and when the latter travels are locked in their upper. position to the cycle-frame. -When stoppingthe cycle, thesesupportingrods may be unlocked by operating a special mechanism, so that the said rods sink down until they are in contact with the road, in which position they are automatically locked The locking of the supporting-rodsin their lower position of use is eifectuated by toothed wheels connected to the axle of the driving wheel. These toothed wheels gear with racks.

of the supporting-rods and, when starting the cycle, lift up automaticallythesupportrear end view, of a cycle furnished with the new mechanism. Fig. 3 is a rear view, on an enlarged scale, of the fork of the rear wheel with the supporting-rods and the means for holding and releasing them. Fig. dis a side view of the mechanism for locking and unlocking the supporting-rods. Fig. 5 is a side view of the mechanism for locking the supporting-rods in their lower position and for,

lifting them up automatically when the rider proceeds. Fig. 6 is a front view of this mechanism; and Fig. 7, an upper view ofthe same, partly in section.

On both sides of the fork o; of the drivingwheel supporting-rods b, with rollers Z), are arranged in rings 0 of the cycle-frame, so that they can slide in these rings, Figs. 1 and 2. These supporting-rods are locked in their upper position by spring-actuated lock-bolts d, which can be retracted from therespective openings (1' of the supporting-rods Z) by two levers f, which can be drawn together by means of a double hook 6, Figs. 3 and 4.

Near the axle of the driving-wheel on each sideof the cycle is arranged a locking device,

'a toothed wheel 2', fixed to the axle of the driving-wheel and gearing with a rack t" of the respective supporting-rod 12, looks this rod against upwardmovement and serves also the purpose to raise the supporting-rod up to its upper position. In order to prevent the wheel 7 from gearing with the rack i during the downward movement of the supporting-rod, the rack t" is connected to the supporting-rod by arms i and is, when the mechanism for unlocking the bolts d is worked,

displaced by means of a beveled lug g of the slide g in such a manner that the supportingrod Z) connected with it turns in the rings 0, .thus removing the rack i from the toothed wheel 2, so that the supporting-rod descends without being checked.

The operation of the mechanism is as follows: When it is desired to stop the cycle without dismounting from it, the rider simply by pulling on a cord or a chain moves down the slide g and the double hook e, the latter being held in its upper position by a strong spring 6' and being connected to the slide 9 by a cord or a chain. By this operation the ends of the double hook e, which slide in slots f of the levers f, draw together the levers fiwhereby the latter withdraw the bolts 61 from the openings'clflso that the supporting-rods b can slide down in the rings 0. At the same-time by the downward move- ICO ment of the slide 9 the lugs pushforward the spring-actuated sleeves 9 so that the racks i are disengaged from the toothed WllOGlSt and descend together with the supporting-rods b. 'When descending, the hookshaped arms 9' of the slides 9 release the spring-actuated lock-bolts 72, by allowing the lugs 7L2, Figs. 6 and 7, of them to enter the curved parts 9 of the arms 1. The said lock-bolts h lean against the supporting-rods l), and the openings h arranged in the latter slide over the rounded upper edges of the bolts 7L until the rollers Z) touch the road. \Vhen, however, the supporting-rods are reasccnded by the cycle being thrown over sidewise, the lock-bolts 72., the lower edges of which are not rounded, spring in the openings 7L and lock the supporting-rods against further ascending. Then the rider, after having stopped the cycle, releases the cord serving to operate the mechanism, the spring 6' draws up the double hook c andthe slide g. By this movement the levers f are spread and the lock-bolts (Z are released, so that by the action of their springs they are pushed against the supporting-rods b. At the same time the ascending hook-shaped arms g withdraw the lock-bolts hfrom the respective openings 7i of the supporting rods, and the sleeves 9 now released by the lugs 9 are withdrawn by their springs. By these means the racks t" are thrown into gear with the toothed wheels 7), which now look the supporting-rods 1) against reascending. When the rider desires to proceed, a special operation for releasing the mechanism is not necessary, for the toothed wheels 2', fixed to the axle of the driving-wheel, when the latter is rotated raise automatically the supporting-rods 1) until the openings (1' of them are opposite the ends of the lock-bolts d. The ends of these lock-bolts d are preferably cone-shaped, so that when entering the openings cl they raise the supportingbars I) still a suflicient distance to bring the lowest tooth of each rack 1" out of contact with the respective toothed wheel '6, thus avoiding the wear and tear of these parts While traveling. Having now described my invention, what I claim is 1. In a cycle a pair of supporting-rods extending downward one on each side of the rear wheel and sliding in guides attached to the cycle-frame, bolts forlockin g the said rods in their upper position, means for unlocking these bolts to allow the supporting-rods to slide down until their ends shall be in contact with the road, toothed wheels connected with the axle of the rear wheel serving for locking engagement with the racks of the supporting-rods in their lower position and for reascendin g the latter when restarting and means for disengaging the racks and the toothed wheels during the descending of the supporting-rods, substantially as described.

2. In combination with the cycle, the supporting-rods extending downward one on each side of the cycle, the bolts for locking the supporting-rods in their upper position, a suitable mechanism for unlocking these bolts, the toothed wheels connected with the axle of the rear wheel, serving for locking engagement with racks of the supporting-rods in their lower position, a slide connected with n rear wheel serving for locking engagement with racks of the supporting-rods in their lower position, the slide connected with the before-mentioned unlocking mechanism and sleeves surrounding the racks cooperating with cam-lugs of the slides for the purpose of disengaging the racks andthe toothed Wheels when the unlocking mechanism is worked; substantially as set forth.

Signed at Breslau, Province of Silesia, Empire of Germany, this 31st day of October, 1898.

CARL SCHREIBER.
