ABSTRACT:
A controller for a railway locomotive is provided having a first control handle which controls propulsion power and braking power, and a second control handle which controls the direction of movement of the locomotive. The controller includes first and second shafts having a plurality of cams fixed thereto for actuating propulsion and braking power control contacts. Additional cams are rotatably mounted on the second shaft for actuating contacts which control the direction in which the locomotive travels. The first control handle is connected to a drive gear which is operatively connected by two lost motion mechanisms to the first and second control shafts. By manually operating the first control handle, the drive gear and two lost motion mechanisms selectively and alternatively rotate the first and second shafts so as to control propulsion power and braking power for the locomotive. The second handle may be manually actuated to rotate the additional control cams about the second shaft in order to control the direction of movement of the locomotive.
