RICHARD SCHRGDLEIN, OF AUSOHA, AUSTRIA-HUNGARY.

CAR STARTER AND BRAKE.

SPECIFICATION forming part of Letters Patent No.'501,447, dated July 11, 1893.

Application filed October 8, 1892. Serial No. 448,287. (No model.)

To aZZ whom it may concern:

Be it known that I, RICHARD SOHRoDLEIN, of Auscha, near Leitmeritz, Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Apparatusfor Braking and Starting Vehicles, of which the following is a full, clear, and exact specification.

This invention relates to apparatus for braking and starting railway cars and other vehicles, and has for its object to provide novel means whereby the momentum of the vehicle, when the brakes are applied, stores power heretofore wasted, which power is utilized for restarting, or assisting in restarting the vehicle at the proper time.

To accomplish this object my invention involves the features of construction and the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figures I and I, when taken together, represent a sectional plan view of my invention in connection with two car axles of a car. Figs. II and II, when taken together, represent a plan view of the same. Fig. III is a cross sectional view taken on the line A A of Fig. I. Fig. IV is a cross sectional view taken on the line B B of Fig. I; and Fig. V is a longitudinal sectional view of the air reser- V011. In order to enable thoseskilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings wherein- The letters a a indicate the axles of a railway car or other vehicle, provided respectivelywith friction gear wheels I) b, and e 6 counter shafts arranged in juxtaposition tothe car axles. The counter-shaft e is provided with a friction-driven gear-wheel d, and with cranks f connected respectively with the piston-rods of pistons K moving respectively in cylinders q. The counter shaft 6 is also provided with a suitable frame comprisin g links 0 which support the journal or axle of a transmitting friction gear-wheel c adapted to be moved into and out of contact with the friction gear-wheel b on the axle a. The frame composed of the link c is pivotally suspended by a frame composed of links a suitably suspended from a horizontal rod .0

in such manner that when the said rod is moved in the direction of the arrow I, Fig. II, the transmitting gear 0 is thrown into engagement with the friction gear-wheel b, and the rotary motion of the car axle a. is transmitted to the gear-wheel d for rotating the counter-shaft e, and thus causing the cranks f to reciprocate the pistons K. An air reservoir n, interposed between the cylinders g, is provided with suitable pipe connections n leading respectively to the cylinders g, and the latter are provided with air valves Z, while the pistons K are provided with air valves 2', all in such manner that when the pistons are reciprocated, as before explained, atmospheric air is pumped into and compressed in the air reservoir n, thereby storing energy to be utilized, as will hereinafter appear.

The counter-shaft e is provided with cranks f connected respectively with the piston g ods of pistons K, having oblique passages a friction-driven gear wheel d, and with a frame composed of links 0 which support the journal or axle of a friction-transmitting gearwheel 0 adapted to be moved into and out of engagement with the friction gear-wheel b on the car axle a. The frame composed of the links a is supported by a frame composed of links 0 pivotally suspended from The counter-shaft e is also provided with the horizontal rod 0, all in such manner that when said rod is moved in the direction of the arrow II, Fig. II, the friction-transmitting gear-wheel c is moved into engagement with the friction-gear wheel I). The pistons K are each formed with an oblique passage Z, which, in the position shown. in Fig. I communicate with the air inlet 7' of pipes or passages q that connect the cylinders g with the air reservoir n. The cylinders g are provided with channels S S and when the parts are in the position, Fig. I and a valve 10 which governs communication with the air reservoir 01. is opened, as hereinafter explained, the compressed air will flow through the pipes or passages q, inlets a", passages Z, and channels S to the spaces 15 behind the pistons K, thereby forcing the pistons toward the opposite ends of the cylinders. When the pistons in their forward stroke come into such position that the oblique passages Z communicate with the channels S of the ports the compressed air will flow intothe spacet in ordertoimpart back stroke to the pistons. The exhausted compressed air passes from the cylinders through the ports to it, which latter open to the external atmosphere.

A check-valve m is provided on the air-reservoir n to permit the air to flow from the pipes or channels 02. into the air reservoir, While preventing escape of the air from the reservoir back through said pipes or channels n.

The horizontal rod 0 is located below the frame of the car or vehicle and the rods of several cars or vehicles constituting a train may be coupled together for simultaneous movement. The rod 0 is provided with a wedge or projection O to engage the valve p, so that when the rod 0 is moved in the direction of the arrow II, Fig. 2, the wedge or projection 0 will open the valve and permit compressed air from the air reservoir n to flow through the pipes or channels q to the cylinders q, as before explained.

In the practical operation of the apparatus, when the brakes of the car or vehicle are applied, the rod 0 is moved in the direction of the arrow 1, Fig. II, thereby throwing the friction-transmitting gear-wheel 0 into gear with the friction gear-wheel b, and operating the pistons K to force air into the air reservoir n, where such air is stored up to be subsequently utilized in restarting the vehicle. In restarting, the steam-valve of the locomotive is opened so that the railway train commences its movement, and the axles of the vehicle turn through a portion of their rotation. The rod 0 is then moved in the direction of the arrow II, Fig. 11, whereby the friction-transmitting gear-wheel c is thrown into gear with the friction gear-wheel Z), and the valve 19 is opened to admit compressed air from the reservoir n to the cylinders q, whereby the pistons K are reciprocated and the counter-shaft e is rotated for imparting a rotary motion to the friction-gear wheel I), by which power is transmitted to the car-axle a for restarting, or aiding in restarting the car or other vehicle.

The apparatus may be arranged on one or more vehicles of a railway train, or on vehicles of any description, and the movements of the rod 0 are effected either by the guard from the interior of each vehicle, or bythe engineer on the locomotive.

The cylinders g, with their pistons and adjuncts, constitute an air pump for compressing and storing air in the reservoir 02, which air is utilized to restart the vehicle through the medium of the cylinders g and their pistons.
