(under subclass 86) Device including means to removably secure a clamp couple element * to a supporting structure which structure serves as a coacting jaw.
(1) Note. The clamp couple element itself, not in secured position, is incapable of holding work.
(2) Note. Included here are patents to a "hold down" used on a machine tool work table as well as a "planking clamp" used for applying a sheathing, floor or wall board.
(3) Note. In the figure below shank 4 of a clamp couple element is maintained in position with respect to support 5 by being canted in opening 3. Actuation of cam 2 then serves to grip work between jaw 1 and support 5. [figure]
