ABSTRACT:
A diaphragm assembly for the ends of railroad passenger cars comprises a head section, a sill section, and a pair of spaced apart upright side sections which connect the ends of the head and sill sections together. Each section is made of a single cast of urethane and is a molded integral section. Each section includes a channel member which has a pair of legs separated at one end and connected together at the bottom of the legs by a base member having a face portion with a hard rubbing surface for rubbing against a similar rubbing surface of an abutting diaphragm assembly. Hard flanges are molded onto the separated ends of the legs for mounting the channel member onto the door frame of the railroad car, and, in the side and head sections, a series of spaced-apart posts extend inwardly from the base member between the legs for insertion into a guide channel on the door frame of the railroad car to prevent lateral movement of the channel member.
