UNITED STATES CARL G. TOENSE, OF CLEVELAND, OHIO.

VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 425,471, dated April 15, 1890.

Application filed August 20, 1889. Serial No. 321,364. (No model.)

To all whom it may concern.-

Be it known that I, CARL G. TOENSE, of Cleveland, county of Ouyahoga, and State of Ohio, a citizen of the United States, have invented certain new and usefullmprovcments in Riding-Cycles, of which the following is a specification.

This invention relates to that class of vehicles that are propelled by the rider; and the object of my invention is to provide a ridingcycle which is operated by means of hydraulic pressure, the rider moving up and down in the saddle in the same manner as he would when riding a horse on a canter or gallop.

The invention consists in the combination, with a suitable frame and steering and driving wheels, of suitable mechanism for rotating the driving-wheels by means of hydraulic pressure. I

The invention also consistsin the construction and combination of parts and details, as.

will be fully described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a side View of my improved riding-cycle. Fig. 2 is a horizontal sectional view of the same Fig. 3 is an enlarged detail longitudinal sectional view of the driving-cylind er, piston-rack, and clutch. Fig. 4 is a cross-sectional view of the rack, showing an end view of the driving-cylinder. Fig. 5 is a horizontal sectional view of the clutch. Fig. 6 is a vertical longitudinal sectional. View of a lower hydraulic cylinder and its piston.

Similar letters of reference indicate'corresponding parts.

The frame A, the rear driving-wheel B, and the front steering-wheel C are of the usual construction, said front steering-wheel being mounted to turn, and being provided with a handle in the usual manner. On the backbone A of the frame the hydraulic cylinder D is secured, which is shown in dotted lines,

and contains the piston D, secured to the piston-rod D projecting through the top of the cylinder, (also shown in dotted lines in Fig. 1.) On the upper end of the piston-rod D the saddle E is secured, and from the same two bars F project downward, the lower ends of which are connected with the forked shanks (l of an angle-lever G, pivoted on an upwardly-projecting lug II of the bottom bars I of the frame. The other upwardly-projecting arm G of said angle-lever G is connected by a rod J with the upwardly-projecting arm K of the angle-lever K, pivoted on the lug II of the bottom bar I of the frame. The forked shanks K of the angle-lever K are provided with notches in their end, through which a cross-rod Opasses, on the ends of which the vertical sliding downwardly-projecting bars L are held, from the lower ends of which the treadles M project laterally.

The cross-bar O is connected with the upper end of a piston-rod P, projecting upward from the piston P in a hydraulic cylinder Q, projecting downward from the bars I of the frame. The bars L are provided with longitudinal slots L, through which guide-pins L project laterally from the sides of the cylinder Q.

The lower end of the upper hydraulic cylinder D is connected by a pipe R with a horizontal pipe R, the opposite end of which is connected with a hydraulic driving-cylinder S, secured horizontally on one of the side bars of the frame. The lower end of the bottom hydraulic cylinder Q is connected by a pipe T with the horizontal pipe T, the other end of which is connected with the driving-cylinder S, held horizontally on that side of the frame opposite the one on which the cylinder S is held. The cylinders S and S each con tain a piston U, with which a rack-bar U is connected, projecting from the open rear end of said cylinder, said rack-bar being suitably guided to reciprocate horizontally. The rackbars U each engage a cog-wheel V, formed on the rim of a clutching-wheel V, having tapering recesses V in which rollers IV are arranged, that can impinge on the rim of a fixed clutching-pulley a, keyed on the axle (Z of the rear or driving wheel 0.

The operation is as follows: When the riderv mounts the cycle and rests his weight upon the seat E, said seat will be forced downward, and thereby the liquid in the upper hydraulic cylinder D is'force'd through the pipes R B into the cylinder 8 and forces the piston in said cylinder in the direction of the arrow on, Fig. 3, whereby the cog-wheel V is rotated in the direction of the arrow 34 and by means of the intermediate clutching-rollers \V rotates the pulley a aXled, and driving-wheel B in the direction of the arrow 00 thus moving the vehicle forward. As, the seat descends the bars F also descend, and by means of the angle-levers G and K pull upward the bars L,

' whereby the piston P in the bottom hydraulic cylinder Q is raised, and the piston U in the cylinder S is moved in the inverse direction of the arrow 00', and the corresponding cog- Wheel V rotated in the inverse direction of the arrow och-Without, however, acting on the axle d. When the seat has arrived at its lowest position, the rider bears down on the treadles M, at the same time raising himself in the seat, whereby the piston of the lower hydraulic cylinderis forced downward an d the liquid forced from said lower hydraulic cylinder into the driving-cylinder S whereby the piston in said driving-cylinder is moved in the direction of the arrow x and the wheel B rotated in the direction of the arrow 00 At the same time the seat is raised, the upward moti on being imparted to the same from the bars L by the angle-levers G K and the connecting-rod J, and thus the piston and rack of the cylinderS are moved in the inverse direction of the arrow as, and so on, for the reason that the liquid is drawn by suction out of the cylinder S, and the pressure of the exterior air, acting on the piston U, moves the same in the inverse direction of the arrow 00, as stated above. The driving-wheel is thus acted upon alternately by the two driving-cylinders, one acting when the seat descends and the other when the treadles are forced down.

The liquid used in the cylinders is either glycerine, oil, water, alcohol, or a, mixture of either of these, as desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A riding-cycle constructed with two hyd raulic-pressure cylinders connected with the seat and treadles, respectively, and mechanism, substantially as described, for transmittin g motion from said hydraulic-pressure cylinders to the driving-wheel, substantially as set forth.

2. In a riding-cycle, the combination, with a frame and wheels, of two hydraulic-pressure cylinders connected with the seat and treadles, respectively, levers and rods connecting the pistons of said two pressure-cylinders, and mechanism, substantiallyas shown and described, for transmitting motion from said pressure-cylinders to the driving-wheel,

wheels, of a driving-cylinder on each side'of the frame, a piston in each driving-cylinder,-

a rack-bar on each piston and cog-wheels engaging with each rackfbar, clutches for transmitting motion from said cog-wheels to the driving-wheel shaft, two hydraulic-pressure cylinders on the frame of the machine, one of said pressure-cylinders being connected with one driving-cylinder and the other pressure-cylinder with the other driving-cylinder,

'a seat connected with the piston-rod of one pressure-cylinder, treadles connected with the piston-rod of the other pressure-cylinder, and angle-levers and rods connecting the pistonrods of the two pressure-cylinders, substantially as set forth.

In testimony that I claim the foregoing asmy invention I have signed my name in presence of two subscribing witnesses.

CARL G. TOENSE.
