Abstract: A grease pump for railroad tracks operable by vertical deflections of the rail caused by the weight of the train as the train wheels pass over the track. The pump comprises a housing anchored to the ground and connected to a grease source. Pump operating means comprise a rigid beam connected to the track rail at one end and to a pump operating rod at an opposite end. The operating rod is connected to a cap-like pressure member fitting over the housing and operable by the rail deflection movement to draw grease through inlet port means from the grease source and pump the grease through outlet port means to a track lubricator. Check valves are provided in the pump to control the grease flow.
