A ramp lever is adjustably supported by a frame secured to the rail of a railway track. The lever has a shaft portion and a car wheel striking portion that extends upwardly from the shaft portion. The ramp lever is rotatably supported by the frame for movement between a raised position and a depressed position. The shaft portion of the ramp lever is connected through an indexing assembly to a drive shaft. A torsion spring extends in surrounding relation from the shaft portion to the indexing assembly. After the car wheel has passed over the ramp lever and depressed the lever, the torsion spring returns the ramp lever to the initial raised position. During the return stroke of the ramp lever to the raised position, the indexing assembly transmits rotation from the ramp lever shaft portion to the drive shaft. The drive shaft is disconnected from the ramp lever as the car wheel depresses the ramp lever to isolate the drive shaft from the shock forces transmitted by the car wheel. Rotation of the drive shaft is transmitted to a roller disc carrying a plurality of rollers adjustably, radially positioned on the roller disc. An anti-regression clutch on the drive shaft prevents backward movement of the drive shaft as the ramp lever is depressed. A lever is pivotally mounted adjacent to the roller disc, and a lubricant pump is operatively connected to the lever. As the roller disc rotates, the rollers move into and out of contact with a cam surface of the lever to intermittently downwardly move the lever and actuate the pump to convey lubricant through a hose to the flange of the rail.
