Abstract

A roller assembly for facilit 114 ating movement of a switch rail between two positions. In one embodiment, the roller 100 assembly includes a frame adapted for at tachment to the switch rail and having a pocket formed therein, and an elastomer as sembly, at least a portion of which is slidably disposed within the pocket. The elast omer assembly includes a roller wheel and an elastomeric block. The roller wheel travels along the surface of a tie plate when the switch rail is moved between positions. The elastomeric block is adapted to com press under a load applied to the switch rail in the direction of the tie plate, causing the roller wheel to retract in the direction of the pocket. When the weight of a train is exer ted on the roller assembly, the compression of the elastomeric block causes the train to ride fully on the rails, just as if the roller as sembly were not present. When no weight is exerted on the roller assembly, the roller as sembly assists the switch to move freely 00© FIG. 4 between positions.
