Abstract
A sheet bending brake comprising a first longitudinally extending member having a clamping surface, a clamping member having a member movable toward and away from the clamping surface for holding a workpiece in position for bending and a second member extending longitudinally with respect to said first member. Each of the first and second members have substantially the entire length of the longitudinal edges thereof formed with longitudinally spaced intermeshing integral projections, the projections on the second member having a plurality of aligned openings and the projections on the first member having a plurality of aligned openings comprising slots extending axially with respect to the longitudinal axis of said member. A hinge pin extends through the openings of the second member and the slots of the first member. The second member has a workpiece contacting portion spaced from the projections. The slots have a configuration such that as the second member is moved relative to said first member to bend a workpiece, the hinge pin is guided along said slots such that the contacting portion of said second member remains substantially in the same position relative to the workpiece. A handle member for manipulating the anvil member is constructed to minimize the stresses thereon. The clamping member is constructed to maximize the strength thereof. A stabilizing assembly is associated with the legs on which the clamping brake is mounted.
