ABSTRACT:
A hanger for supporting single or multiple conductor rails in a rail-type electrification system, comprising a cross support member extending transversely of the rails and one or more spring clips carried by the member and having legs adapted to clamp against opposite faces of the rails so as to support them in operative positions. Each clip is movable on the member between extended and retracted positions, and has resilient latching fingers which cooperate with two sets of shoulders on the member. One set of shoulders prevents inadvertent removal of the clip when it is disposed in its extended position, and the other set operates to lock the clip in its retracted or operative position. In the extended clip position, the legs of the clip are separable an extent to permit insertion of a conductor rail therebetween. After insertion of the rail, the clip is driven to its retracted position, wherein the legs are engaged by wall portions of the support member and thus prevented from spreading and inadvertently releasing the conductor rail. The clip is held in this retracted position by the engagement of its latching fingers and the one set of shoulders of the support member. The arrangement is such that installation involves merely pulling a clip from retracted to extended position, and inserting a rail into the clip, after which the assemblage is manually seated in the cross support member by means of a hammer blow or gentle urging by a pair of pliers, etc.
