A jaw for use in a clamp in which there are two relatively movable jaws on a frame to clamp board stock between them, said jaw including a body and a face plate having a rib abutting the face of said body as a horizontal fulcrum for rocking of the face plate, and a spring device engaging both said body and the rear side of said face plate on at least one side of said rib and constituting a resilient mounting of said face plate on said jaw body providing for even distribution of the clamping force to the upper and lower portions of the boards, one form of the resilient mounting means including two brackets held on the jaw body by a tension spring connecting the brackets and extending in a groove across the front side of the face plate, each bracket having resilient arms engaging the back of the face plate at opposite sides of said fulcrum.
A clamp jaw for use in a clamp wherein there are two relatively movable jaws on a frame and means to cause relative movement of said jaws to clamp and release stock between the jaws, said jaw comprising a body having a face, and a face plate rockable on said body on a horizontal axis, said face plate having on the rear side a curved fulcrum rib intermediate its upper and lower edges abutting said face of the jaw and providing said axis, means for mounting said face plate on said jaw comprising a spring device including parts engaging both said body of the jaw and the front of said face plate and the rear side of said face plate on at least one side of said rib means holding said face plate on the jaw body, and means providing resilient rocking action of said face plate on said axis.
