ABSTRACT:
A support bracket apparatus for mounting a transformer rack or other device on a vertical support member such as a wooden pole, is disclosed. The support bracket apparatus includes a pair of hanger members fastened to the opposite sides of the pole by an adjustable fastening means which adjusts the spacing between the hanger members to accommodate different pole diameters. When used to support an electrical transformer rack, a pair of hanger members is employed at each end of the rack which have lower leg portions in engagement with a pair of mounting arms extending from the rack to support the weight of the rack and transformers on such hangers. The adjustable fastening means preferably includes a plurality of threaded sleeves which extend outwardly from an upper leg of the hanger member and threaded collars which engage the projections so that changing the rotational position of the collar adjusts the spacing between the two hangers. Mounting bolts extending through the sleeves and holes in the support poles are attached by nuts to the mounting arms of the transformer rack to mount the assembly on such poles. Alternatively, the threaded sleeves and collars may be replaced by shims on the mounting bolts to adjust the spacing between the hangers. The support rack is in the form of a hollow box beam made of laminated wood members having a concave curved notch in each end closed by a sheet metal cover to provide the two mounting arms on opposite sides of the pole.
