Application filed Aeptember IA, 1916. Serial No. 120,656.

To all whom it may concern."

Be it known that I, OTIS W. YOUNG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Engine Reversing- Gears, of which the following is a specification.

My invention relates to improvements in engine reversing gears. It has for one object to provide a new and improved means whereby the engineer in the cab of a railroad locomotive may control the reversing shaft. I have illustrated my invention as applied to a locomotive with a reversing shaft wherein two portions of the reversing shaft are driven by separate levers'for rotation in opposite directions to control the mechanism. I have not gone exhaustively into the description of the shaft itself because that forms no part of my invention.

My invention is illustrated more or less diagrammatically in the accompanying drawing wherein Figure 1 is a side elevation of my device with parts omitted and parts removed;

Fig. 2 is a detailed plan view.

A is a locomotive frame adapted to be supported by means of the usual wheels and axles as suggested in dotted lines. A is a part of the boiler. A is a part of the frame adjacent the cab. A is a throttle lever pivoted on the bracket A on the frame A having a hand piece A. A is the usual: type of quadrant to guide the lever. A is a reach rod pivoted at one end on the lever A and terminating at the other end in a knuckle joint A whereby a connection is made with a sliding or traveling member B.

This sliding or traveling member 13 is guided by the bearing sleeves 18 B on a reversing gear frame 18 which frame is supported on the engine. frame A in the usual manner. This sliding or traveling member 18 is free to slide in these bearing sleeves responding in its movement to the rocking movement of the throttle lever.

C is a reversing shaft supported on the forward end of the frame B 'Ihis reversing shaft assembly has rock arms (3, C concentrically mounted and free to rotate independently C rigidly and U rotatably mounted on said shaft. Links C C connect these rock arms and the sliding or traveling member B so that as the sliding or traveling member B moves back and forth controlled by the hand of the operator the links cause the rock arms to move back and forth assuming the position shown in dotted lines.

I have not shown the connection from the reversing shaft to the engine reversing gear as, of course, this might be any suitable connection and its operation is, of course, clear to any one skilled in the art.

It will be evident that while I have shown in my drawing an operative device, still many changes might be made both in size, shape and arrangement of parts without departing from the spirit of my invention, and I wish, therefore, that my drawings be regarded as in a sense diagrammatic.

I claim:

Alocomotive reversing gear comprising a supporting frame, a reversing shaft rotatably mounted upon the frame, a crosshead slidable upon the frame along a line perpendicular to the axis of the reversing shaft, rocker arms mounted upon the shaft free to rotate independently, one rigidly and the. other rotatably mounted on the shaft, links interposed between the free ends of the rocker arms and the cross head pivoted at til a single axis upon the cross head, a controlling lever pivoted at one end, a connectin
