CYCLE.

SPECIFICATION forming part of Letters Patent N 0. 572,544, dated December 8, 1896. Application filed May 4, 1896. Serial No- 590,240. (No model.)

To (ZZZ whom it may concern.-

Be it known that we," Gnone CHRISTIAN WILHELM HIPPERLING and WILHELM AN- TON DIETRICH HIPPERLING, subjects of the Emperor of Germany, and residents of Wandsbeck-Hamburg, in the Empire of Germany, have invented new and useful Improvements in Cycles, of which the following is a specification.

This invention has for its object a contrivance for retaining constant, irrespective of the weight, the distance between the saddle and the pedals on such cycles as have a spring arranged for carrying the saddle as a substitute for the pneumatic tires.

On the drawings, Figure 1 shows a side View of the contrivance, partly in section; Fig. 2, a front view, partly in section.

The saddle a is fastened on the right-an gled rod 1), by which it can be fixed at any desired height in the tube a. The upper part of the tube is inserted into the frame cZ and its lower part into the cross-piece e by means of the rod f, bent forward below the latter. Around the tube 0 a strong spiral spring g is placed, the lower end of which presses against the plate h, resting on the cross-piece e, and the upper end against the plate h. The latter abuts against the nut Z, which can be screwed up and down on the tube 0, which is here provided with a thread in order to give the spring 9 tension in proportion to the weight on the saddle a. This spring g serves for taking up the jolting and renders pneumatic tires superfluous.

The forwardly-bent anglearn1f' of the rod f is, by means of a bolt k, linked to the like operating-levers Z Z.

of these levers are formed by the bolts m m of the arms at n, fastened on the frame A,

The points of support while the bolts 0 0 lie in such manner between the bolts m m and the common bolt 70 that forms a proper fraction, that is, m0

must be shorter than 070. The bolts 0 of the levers Z Z are linked with the common bolt q, lying in the slots 10 in the connecting-rods M. This bolt q forms at the same time the fulcrum for the treadle-levers a" 1". The ratio of the free longer arm to the short arm of each of these treadle-levers is likewise It is therefore obvious that with any weight operating on the saddle in consequence of the above-described lever transmission the distance between the saddle a and pedal 8 always remains the same.

The shorter leverarm of the treadle-lever r (or r) is connected in any known manner with the crank 15, which is mounted on the shaft 20 of the chain-wheel o.

What we claim is-= In a contrivance for retaining constant the distance between the saddle and the pedals of cycles the combination of the two levers Z Z, linked to the saddle-rod, with the bolt It, the spring g, the stationary bolt m, on which the levers Z Z are turned, the bolts 0, the connecting-rods u, the bolt g, which on the yielding of the saddle a, yields as much as the bolts 0, so that as the lever-arms of the lever Z have the same proportion, as the treadlelever arms, the pedal 3 always remains equidistant from the saddle, as described.
