Abstract
Abstract A connector for securing the signal arm of a traffic signal device in fixed, spaced relation with respect to the mastarm which comprises a generally Y-shaped clamp having a hollow cylindrical base and a pair of divergent legs with clamping means at the ends of the legs for securing the clamp to the signal arm and a mastarm clamp having a pair of transversely extending ears with a central concave portion therebetween, and a cylindrical hub connected to the central cancave portion. The mastarm clamp also includes a pair of cables which extends from one transversely extending ear around the mastarm to the other transversely extending ear with means for tightening the cables around the mastarm. The cylindrical base of the signal arm clamp is provided with a cylindrical recess adapted to receive the cylindrical hub of the mastarm clamp. The forward surface of the cylindrical hub is provided with radial serrations which are adapted to mate with radial serrations on the bottom surface of the cylindrical recess. A bolt extends axially through the cylindrical hub and the cylindrical base and is provided with a nut at one end thereof to permit the tight securing of the cylindrical hub in the cylindrical base.
