ABSTRACT:
A sheet bending brake comprising a plurality of C-shaped frame members that support a first member. The first member has a clamping surface. A second member is hinged to the first member and has a bending surface. A plurality of bars are pivoted to the frame members and support an anvil member that extends longitudinally of the first member. A cam support shaft is rotatably mounted on the frame members and a plurality of eccentric cams are secured on the shaft. Each bar is generally C-shaped and a cam is positioned between the upper and lower flanges thereof. A handle is secured to the shaft such that when the handle is operated, the eccentric cams are rotated to move the bars and, in turn, the anvil member into and out of clamping position. A cover is provided on each bar to enclose the cam.
