Abstract
An apparatus for maintaining a railcar coupler key in position to releasably secure a railcar coupler shank to a yoke accommodated in a sill of a railcar. The railcar coupler key retainer apparatus includes an elongated key stop adapted to be releasably secured against an interior surface of a sill side wall defining an elongated slot. The key stop is configured with a flange portion which projects beyond an exterior surface of the sill side wall defining the slot. The flange portion defines a through bore having a closed margin. A retainer is mounted to the exterior surface of the sill side wall defining the elongated slot and defines a through bore which aligns with the through bore in the flange portion of the key stop when the key stop abuts with a closed end of the elongated slot defined by the side wall of the sill. A locking member is received in the through bores in the key stop and retainer to releasably secure the key stop to the interior surface of the sill side wall and thereby maintaining the railcar key retainer apparatus in position to maintain the railcar coupler key between the side walls of the sill and in position to secure the yoke to the coupler shank.
