Description

Clamp device of steel consisting of a body (1 1/4" x 2 5/16" x 6 1/8") made up of a block with a machined recess in the center of one side extending only part way to the bottom. In this recess, a piece of wood is sandwiched between recess and a steel plate riveted to the body. The wood extends to 5/16" below top of the body and it fills the 1/8" recess depth. At the body back near each end, a 1/4" diameter set screw is inserted into a tapped hole such that their tops extend about 5/16" above the top of the body. A clamp bar, also steel fitted with a .4" screw at each end, can't be tightened against the set screw tops by means of these two screws.
