ABSTRACT:
An electric traffic signal is supported from a horizontal mast by a bracket assembly comprising (1) upper and lower signal-supporting bracket arms located at the upper and lower ends of a vertical tube, (2) a swivel supporting the tube for vertical and angular adjustment and (3) a saddle pivotally supporting the swivel and adapted to be attached to the mast by a pair of clamping bands. Pressure plates are located in the saddle and are adapted to be adjusted to take up the slack in the bands and thereby cinch the bands tightly around the mast. Conventional muffler clamps are used to attach the bracket arms to the tube and to attach the tube to the swivel. A cylindrical rod made of elastomeric material closes an elongated slot in the rear of the tube, the slot enabling electrical leads for the traffic signal to be threaded into the tube.
