The head portion of a railway car coupler is provided with forwardly projecting horizontal upper and lower shelves. The leading edge of the top shelf is angled upwardly and rearwardly to provide clearance for coupler droop. Additionally, the leading angle of the coupler can be extended upwardly to establish an improved relation between the leading edges of the mating couplers, thereby minimizing the tendency to have one leading edge slipping under the other during a droop condition of the couplers. |
