An improved adjustable overhead sign bracket system of the type having: a supporting cable clamp, adjustment in the plane of a supporting cable for setting lateral angle of a sign, adjustment about a substantially vertical axis for setting direction in which a sign is to face, and provision permitting a sign to swing in the plane of the direction in which facing to lessen the magnitude of wind loads, provides improved access and swinging clearance at the adjustment about a substantially vertical axis, in the form of a centrally located vertical locking bolt as slim shank portion of an integral inverted "T" member, the lower, substantially horizontal portion of which is a compact sleeve for a pivot bolt providing for the swinging of a sign suspended from it by a sign frame having upward arms engaging the pivot bolt; for economy and versatility in wrenching operations and adjustment in fabrication if desired, the vertical locking bolt may be a conventional bolt with head welded to the sleeve, and a nut and backing plate welded in a place on the threaded end permitting capture and tightening by a nut on the threads of the elements providing the vertical-axis adjustment; a force-fitted protrusion-end "Nylon" bushing in the sleeve coacts with the upward arms and pivot bolt fixed in them to minimize wear.
