CYCLE-REST.

SPECIFICATION forming part of Letters Patent No. 709,588, dated September 23, 1902.

Application filed December 16, 1901. Serial No. 86,117. (No model.)

T0 a/ZZ whom, 7125 may con/cern:

Be it known that I, HANS ULRICH von TROSOHKE, a subject of the Emperor of Germany, residing at Hanover, German Empire, have invented certain new and useful Improvements in Cycle-Rests; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form part of this specification.

The present invention has reference to improvements in cycle-rests, and relates more especially to a bifurcated rest hinged to the frame of the cycle near the crank-axle bearing, which ordinarily lies close to the frame, but which when needed drops by its own weight, aided by a spring, into an approximately vertical position, thereby coming in contact with the ground in two places, on either side of the cycle, and consequently preventing the cycle from tilting sidewise; and the object of the invention'is to provide a rest of the type specified which will fall into the working position automatically without being aided therein by a separate mechanism operated by the rider, as is the case with all of the rests now in use.

In order to make the invention more readily understood, I have illustrated it on the accompanying sheet of drawings, in which-` Figure l represents` a side elevation of a cycle-rest according to 1n y invention attached to the frame-tubing, which is only shown in portion and in the working position. Fig. 2 is a front elevation of same. Fig. 3 is a sectional elevation of the yoke-clam p, which fastens over the rear fork-tubes. Figs. fl and 5 represent slight modifications in the construction of the clamping parts. Fig. represents a side elevation of a cycle provided with the improved rest in working position, and Fig. 7 is a section according to line A A of Fig. 5.

The rest proper consists of two suitablybent legs a et, connected by means of crossbraces b c and having the pin d as pivot. The lower ends run out into points e and are provided with small disks fto prevent the legs d from sinking too deep into the ground. The pin d is journaled in the clamping part m, fastened to the frame-tubing in any desirable manner. As shown in Figs. l and 2, the clamping part m is secured to the frametube y by means of converging aps or extensions n, which are held together by bolts 0 and nuts p. The rear end of the clamping part m is extended and is carried around the axle-bearing .e and runs out into a doubleyoke clamp part q, to which is secured the corresponding clamp part q by means ofthe bolt 1". This double yoke is clamped around the legs oc of the rear wheel-fork, as is clearly shown in Fig. I. To the lower clamp part q is attached a ring or eye s, into which is hooked the one end of a helical spring Z, the other end of which engages a ring j, secured upon the crossbrace c. A flexible wire, a chain, cord, or string 7c is secured with the one end to a ring g, fast upon the brace b, is carried through an eye h upon the clamping part m, and can be adjustably secured with its other end t' upon the cycleframe, near the handle-bar, by being hooked over hooks provided at different heights upon the frame. Ordinarily the rest is caused to lie close to the frame-tube y, as shown in dotted lines in Fig. 6, and this is attained by pulling the wire or string c and fastening the free end to the highermost hook on the cycleframe. The spring Z thereby is extended. If it is now desired to use the rest for steadying the cycle, the upper end of the string or wire k is freed, allowing the rest to swing downwardly about its pivot d partly by its own weight and partly by the action of the new contracting-spring l. The rest then takes the position shown in strong lines in Fig. 6.

In Figs. 4 and 5 are shown modifications in the construction of the clamping parts, which, however, in no way interfere with the construction, arrangement, and working of the other essential parts. In Fig.4 4; the extension m' of the clamping part m is bent farther upward than shown in Fig.. I, so that its clamp end t surrounds the saddle-frame tube w, a bolt o and a nut p being used to draw the clamp halves together.

In Fig. 5 the clamping part fm and the clamp t are secured upon the respective frametubes y and fw by clamping-bands u being pressed around them and the tubes, as is clearly shown in Fig. 7.

I do not claim any particular way of securing the clamping part to the cycle-frame; but

What I do claim, and desire to secure by Letters Patent, is-

In a cycle-rest the combination of a clamping part adapted to be secured to the frametubing close to the crank-axle bearing, a pin journaled in said clamping part, a bifurcated rest composed of two legs symmetrically bent out ofthe middle plane of the cycle, said legs being pivoted on said pin, cross-braces connecting the bent legs of the said rest, an extension of the said clamping part adapted to partly surround the crank-axle bearing, a clamp forming the end of the said extension adapted to be clamped about the frame-tube supporting the saddle or the legs of the rear zo HANS ULRICH VON TROSGHKE.
