Quick release clamp

A quick release clamp comprising

• a base member having an upstanding arm unitary therewith,
• a clamping face associated with said arm,
• screw actuated, clamping means projecting from said upstanding arm to said clamping face, holding means for holding a work piece in a position apposed to said clamping face, said clamping means, in the clamping position, being aligned in a centerline essentially normal to said arm and being operative to move said clamping face toward clamping position and to apply pressure to a said work piece, and
• quick release means associated with said clamping means operative to move said clamping face from its normal position to a position in which it is no longer apposed to the work piece and said clamping means is no longer aligned with said work piece, in which said quick release means comprises a pivoted block into which said screw actuated clamping means is threaded, whereby, when said block is rotated about its pivot, said clamping means and said clamping face will be swung out of alignment with the work piece, and in which said pivoted block is L-shaped, in which said screw actuated clamping means is threaded into the short leg of the L, in which the long leg is pivoted adjacent its end, and in which in the aligned position, the short leg abuts the inner side of said arm, whereby the pressure engendered by tightening up said clamping means is transferred through said short leg to the arm on which it abuts, and the bight of said L is so positioned relative to the bottom of the arm to which the block is pivoted, that on rotation of the block about its pivot, the short leg is rotated out of abutment with the inner face of said arm.
