ABSTRACT:
A woodworking corner clamp assembly having two screw clamp assemblies, each clamp assembly being oriented perpendicular to one leg of an L-shaped frame. Each clamp is also capable of longitudinal sliding movement along one leg of the L-shaped frame. The longitudinal position of each clamp along the respective leg of the L-shaped frame is controlled by the rotation of a threaded rod which passes through a longitudinal slot located in the leg of the frame and through a portion of the base of the clamp member, such that rotation of the threaded rod causes the clamp to be driven longitudinally along the length of the frame.
