Abstract
An improved type 'E' railway coupler with a top and bottom shelf is provided for reducing the possibility of derailments of railroad cars caused by accidental disengagement of interlocking couplers. The improved coupler has a top planar surface for fixedly carrying the top shelf and has a bottom planar surface for fixedly carrying the bottom shelf. The top shelf includes an upper abutment surface limiting the upward vertical movement of a mating coupler and has a set of downwardly-extending coplanar pads seated upon the top planar surface. The bottom shelf includes a lower abutment surface limiting the bottom vertical movement of a mating coupler and has a set of upwardly-extending coplanar pads positioned against the bottom planar surface.
