ABSTRACT:
An improved railway coupler head is provided having a modified lock chamber which is asymmetrical about its longitudinal center line such that the rear horn wall has a greater length on the guard arm side than the knuckle side of the longitudinal center line and the knuckle side wall has a shorter length than the guard arm side wall. The modified lock chamber creates an increase in the section area of the top face of the coupler head and allows for a reduction in stress concentration as the forces transmitted through the top face are distributed over the increased section area.
