ABSTRACT:
A railway coupler housing includes a bottom wall section with a thrower hole extending therethrough and spaced from a side wall diverging outwardly from the horn line at the knuckle side of the housing. The side wall continues vertically from the bottom wall section at a rearwardly-spaced relation from the thrower hole along a sufficient height to permit a generally vertical dropping of the thrower within the interior of the coupler head for engaging a trunnion of the thrower in the thrower hole. The thrower in one embodiment has an extended trunnion provided with a diametrically-extending bore to receive a cotter used to retain the thrower in the coupler head. In another embodiment, the end surface of the trunnion includes a tapped hole for receiving a threaded shank of a stop piece. The stop piece includes projecting wing portions that engage with the outer surface of the bottom wall to prevent inadvertent dislodgement of the thrower in the coupler head.
