Claim 1
Independent Claim
256 words
A universal mounting pad for anchoring any of several different sizes of electrical transformers, which comprises a generally flat deck having a top surface, two ends and two transverse sides; ground engaging support means extending downwardly from said deck; an opening extending through said deck adjacent one of said ends and disposed between said transverse sides; two oppositely disposed recesses in said deck extending outwardly from said hole, each recess disposed parallel to said ends; each of said recesses having a flat bottom surface recessed below said top surface of said deck by a predetermined depth; a channel mounting member secured within each of said recesses, said member having a depth substantially equal to the depth of said recess and a longitudinal axis substantially aligned with the longitudinal axis of said recess, with the open portion of said channel mounting member being on the uppermost surface of said member and adapted to retain therein connecting means which attach the transformer to said pad; a plurality of additional recesses in said deck, each recess having a bottom surface depressed below the level of said top surface of said deck; and anchoring means cooperating with said additional recesses to anchor said pad to the underlying ground to substantially prevent the movement of said pad in lateral and vertical planes, said anchoring means comprises a shaft having at one end thereof earth engaging means and near the other end thereof a radial collar which engages the bottom of the additional recess and screw threads for engagement with a nut.
