Abstract
A clamp for key duplicating machines includes a support, a pin emerging therefrom with a threaded upper end engagable by a knob, the support base having a pair of upper parallel projections on opposite sides of the pin, a lower jaw of square plan, positioned on the support and having a central hole rotatably engaged by the pin, with four grooves in its lower surface parallel to the jaw sides and engagable in pairs with the projections, an upper jaw of square plan, having a central hole rotatably engaged by the pin and cooperating with the lower jaw to clamp a key, wherein the pair of projections are shaped as parallel cylindrical pegs emerging from the upper surface of the support. When the clamp is active, its lower jaw rests only by two grooves on the two projections, otherwise the lower surface is spaced from the support upper surface.
