Abstract: A combined rotary pulse generator and odometer assembly for the axle of a railway locomotive simultaneously generates a speedindicative electrical signal and digitally totalizes mileage traveled. The assembly includes a pulse generator which has a shaft coupled to the end of a locomotive axle to develop electrical pulses as the axle turns. A novel odometer assembly, mounted on the cover plate of the pulse generator, converts the rotary motion of the generator shaft to oscillating motion to drive a digital mileage counter and record accumulated mileage for the locomotive. The odometer assembly is easily converted to accommodate different sizes of drive wheels and different units of distance, and the digital accumulated mileage display is positioned for maximum legibility under poor lighting conditions.
