ABSTRACT:
A clamp assembly for use in constructing a picture frame consists of two superposed, separate plates. One plate has a threaded aperture for receipt of a jacking screw, and the other has a recess for engaging the tip of the screw, the axes of which are offset when the lateral edges of the plates are in mutual registry. Advancement of the screw separates and shifts the plates, thus exerting lateral as well as a transverse gripping forces upon the frame members.
