Abstract
An improved clamp assembly includes a first clamp jaw having a plurality of incremental teeth on a lower surface which selectively mate with teeth on a clamp body. The teeth on the first clamp jaw end at one end at a tooth root and at the other end on an incline beyond and above the predetermined location of a tooth root. In this way, the first clamp jaw may be reversed to provide fine control over the incremental adjustable position of the first clamp jaw relative to the clamp body. In another feature of the present invention the other clamp jaw is a wedge-type clamp jaw having a threaded member with two enlarged portions received in a bore in the clamp jaw. The enlarged portions ensure that the threaded member is effective to move the wedge clamp jaw upwardly and downwardly relative to the clamp body. This is an improvement over prior art wedge-type clamp jaws which required complicated spring arrangements.
