ABSTRACT:
The present invention involves the addition of a device attached to each of the follower block side walls in order to prevent metal-to-metal contact between the follower block side walls and the center sill side walls. The preventative device comprises an elastomeric wear pad attached to a base plate, a base plate being anchored to each of the follower block side walls. The pads are made of a softer, low-friction material, compared to the carbon steel side walls. Since the elastomeric wear pads are softer than the center sill side walls, only the restrictive means will wear, thereby preventing destruction of the center sill side walls no matter how much slack has been developed in the coupling system. The present invention is also adaptable to either E or F type couplers.
