Attorney, Agent or FirmAbstractA cable bender includes two bending members rotatably joined together about a common pivot axis, one of the bending members having a hydraulic cylinder associated therewith such that force may be applied causing the piston shaft of the cylinder to extend and cooperate with a tie arm extending between the bending members to drive one of the bending members in a curved path about the pivot axis.Field of SearchDeforming indeterminate-length workWith pivotal tool (e.g., sheet metal bender) Curved die surface With coacting movable tool Clamp rotatable about fixed axis (e.g., bending brake) Clamp structure constitutes sole initial metal-deforming force-reaction means (i.e., is passive tool) With means to rotate clamp about fixed axis Pivotal motion only Cantilever bender BY OR WITH WORK-CONSTRAINER AND/OR MANIPULATED WORK-FORCER Comprising lever manipulated to force work | |
