KARL SCHILLER, OF IKOW, AUSTRIA-HUNGARY.

AUTUIVIOBILE CAR..

SPECIFICATION forming part of Letters Patent No. 691,078, dated January 14, 1902.

Application filed January 27, 1900. Serial No. 3.053. (No model.)

To all whom t 71mg/ concern.'

Be it known that 1, KARL SCHILLER, a citizen of the Empire of Austria-Hungary, residing at Zikow, near Prague, Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Automobile Cars, of which the following is a specification.

The motive force for actuating the driving mechanism of automotor-vehicles up to the present time has been gas or vapor or steam. The working pistons are in direct communication with the crank-shaft by means of crosshead and connecting-rod, and the whole arrangement is that of a small kind of gas, benzene, or petroleum motor arranged on a suitable vehicle-frame. The drawbacks resulting from such an arrangement-the noisy vibratory motion (produced by an explosion at every piston-stroke) and the escape of steam, gases, and vapors-are too Well known to need demonstration or investigation.

The motor arrangement of the present automotor-vehicle is based on the fact that by the employment of small edorts considerable hydraulic pressures are obtained, and the practical application of this principle, together with au arrangement for the purpose of obtaining an even and uniform working, forms the object of the present invention.

In the accompanying drawings a driving` mechanism as mounted is schematically represented.

Figure l is a plan View, and Fig. 2 a side Fig. 3 is a side elevation of a portion of a vehicle, illustrating the brake device.

The liquid to be employed is carried in a reservoir ct on the vehicle and is drawn from it and propelled into a receptacle c by a pump h. i The receptacle c communicates by means of a pipe or pipes CZ with the inlet-orifice of a slide-valve e, While the exhaust or outlet orifice communicates with a pipe q, returning to the reservoir a. The pistons of the Working cylinders drive the operating-shaft n by means of a device to be described hereinafter, which shaft by means of suitable toothed gearing drives the wheels of the vehicle. lVithout entering into detailed description of the mechanism constituting such a vehicle-for instance, cylinders g, steering and reversing gear, and the like-it should be stated that the pump-piston is most conveniently actuated by means of pedals. By this means it is possible to force the liquid from the vessel c through the pipes d and cylinders g, thereby effecting the driving of the vehicle. In order to render the working free of shock and vibration, the piston-rod connection of the driving-gear is formed of two sleeves 7a and h, one telescoping into the other, the latter being rigidly connected to the piston-rod t, while the other is connected by means of a pin-joint with a connectingrod Z. In the hollow space formed by the two sleeves is arranged a spring o, which takes up some of the pressure from the piston. This pressure may be made effective in a variety of ways-viz., by the arrangement of a brake Wheel or disk p on the driving-axle, by means of which the work produced by the pistons is transmitted after a longer or shorter time, by means of the spring o, inclosed between the sleeves 7L and 7c, directly onto the driving-axle n, or is stored up in the said spring. In operation when the pedals are actuated liquid will be forced into the cylinders and the hydraulic pressure generated therein will be transmitted to the piston and piston-rods and from the latter to the springs o, which latter in turn transmit such pressure to the connecting-rods Z and thence to the drivingaxle. The springs, as will be seen, act to cushion the initial movement of the pistonrods, and it is only after the latter have traveled a portion of their stroke that the pressure stored upin the springs by the movement of the piston-rod will be transmitted to the connecting-rods l. Thus by the introduction of the liquid into the cylinders and the exhaust of such liquid back to the reservoir a the vehicle will be impelled and all shocks due to the operation of the piston-rod will be avoided. By means of such an arrangement it is easy to make use of the force stored up in the spring during the forward or return stroke ot' the piston by either releasing or applying the brake in the iirst case, while in the second case the spring, owing to the force still stored up in it, tends to drive the piston to its initial position, thereby forcing out the liquid from the corresponding cylinder.

The connection of the spring-controlled mechanism with the brake-wheel, on the one hand, andthe combination of these two mech- IOO anisms with the pistons actuating hydraulically the connecting-rods form the chief features of the present invention.

'What I claim as my invention, and" desire to secure by Letters Patent, is-

l. In a driving mechanism for automotor- Vehicles, the combination with a liquid-reservoir, a piston-cylinder, connections between the latter and the reservoir, a piston operating in the cylinder, the piston-rod, a drivingshaft, a connecting-rod connected at one end with the driving-shaft, and a spring connection between the opposite end of the connecting-rod and the piston-rod.

2. In a driving mechanism for automotor- Vehicles, the combination with a liquid-reservoir,of a piston-oylinder,connections between the latter and the reservoir, a piston operating in the cylinder, the piston-rod, a drivingshaft, a connecting-rod connected at one end with the driving-shaft, sleeves on the connecting-rod and piston-rod and telescoping one into the other, and a spring interposed between the sleeves, in the manner and for the purposes specified.

3. In a driving mechanism for automotorvehicles, the combination with a liquid-reservoir a, a pump b, pipes d and q, cylinder g, a piston operating in the cylinder, the pistonrod, the driving-shaft, a connecting-rod connected at one end with the driving-shaft, sleeves h and le arranged as described, and a springinterposed between said sleeves for the purposes specified.

4. In a driving mechanism for automotor- Vehicles, the combination with a liquid-reservoir,of apistoncylinder,con nections between the latter and the reservoir, a piston operating within the cylinder, the piston-rod, a driving-shaft, a connecting-rod connected at one end with the driving-shaft, a spring connection between the opposite end of said connecting-rod and the piston-rod, a road-Wheel shaft geared to the drivin g-shaft and a brakedisk mounted on the road-wheel shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I

KARL SCHILLER.
