Bus bar terminal means for pairs of circuit-braking elements

Claim 1

For use with two pairs of circuit-breaking elements having points of connection aligned in a plane, terminal means comprising an outer substantially rigid bus bar whose span between its ends equals the spacing between the two outermost of such aligned points of connection, an inner substantially rigid bus bar whose span between its ends equals the spacing between the two innermost of such aligned points of connection, the ends of said bus bars being prong-like, Whereby to facilitate securement to such points of connection, the portions of both bus bars between their ends being U-shaped and proportioned according to their spans, whereby when viewed perpendicular to said U-shaped portions, the inner bus bar is throughout its length spaced inwardly of the outer bus bar, said proportioned portions being formed in parallel planes offset from the plane of said prong-like ends when said ends are so aligned for connection, the plane of the inner bus bar portion being offset forwardly of the plane of the outer bus bar portion, each said offset portion having a mounting flat, and a supply wire connector lug mounted on each said flat in electrical contact therewith; whereby to maintain electrical spacing between the bus bars and to avoid contact between the outer bus bar and a supply wire to be connected to the lug on the inner bus bar.
