ABSTRACT:
A sheet bending brake and stabilizing assembly wherein the sheet bending brake alone is constructed and arranged such that when a workpiece is clamped for bending when a person stands on the floor facing the handle means and the handle means is grasped and raised in a direction away from the person in order to move the handle means and raise the handles means, forces occur which prevent the handle means from moving sufficiently to produce a predetermined bend and the forces causes the entire sheet bending brake to tip away from the person about the portions of the legs which project outwardly from said bending brake and thus prevent the movement of the bending member relative to the first member and prevent bending of the workpiece. The stabilizing assembly for counteracting such forces on the sheet bending brake comprises transversely spaced rails receiving at least a portion of the ends of the leg assemblies. The transversely spaced rails which receive at least a portion of the leg assemblies have portions extend outwardly from beneath the sheet bending brake beyond the brake toward the side of the brake from which the handle member and handle means are accessible. Longitudinally extending rail interconnect the transverse rails. The longitudinally extending rail is attached to the portions. The weight and positioning of the sheet bending brake, leg assemblies and rails are such that a person standing on the floor and facing the side of the brake, grasping and raising the handle means at desired bend without tipping.
