Claim 1
Independent Claim
293 words
A jack frame for an electrical jack of the type having a plurality of jack springs and adapted for side-by-side mounting in an electrical jack panel, said jack frame being cast as an integral unit and comprising: a jack sleeve mounting section having a rearward surface, a generally flat forward surface and a pair of side edges; at least two jack sleeve members integrally cast with said forward surface and extending outwardly at right angles therefrom, said jack sleeve members being generally cylindrical members and having a generally cylindrical opening extending therethrough; an elongated jack spring mounting section integrally cast with said rearward surface of said jack sleeve mounting section between said pair of side edges and between two adjacent jack sleeve members, said elongated jack spring mounting section including first and second opposing edges and extending outwardly at right angles from said rearward surface in a direction opposite said jack sleeve members such that said first and second opposing edges are substantially flush with respect to said pair of side edges; means near the outer end of said jack spring mounting section for mounting a plurality of jack springs; and said elongated jack spring mounting section further including a pair of integrally cast reinforcement ribs extending laterally otwardly in opposite directions from each of said first and second opposing edges such that one of the reinforcement ribs of each of said pairs of reinforcement ribs includes a portion extending past a projected extension of the cylindrical opening of one of said two adjacent jack sleeve members and the other reinforcement rib of each of said pairs of reinforcement ribs includes a portion extending past a projected extension of the cylindrical opening of the other of said two adjacent jack sleeve members .
Claim 2
Dependent Claim
