Abstract:
An apparatus for bending malleable metal rods, said apparatus comprising:a base plate having a plurality of holes formed therein, said holes being arranged in rows and columns;a locking cam member having an ovoid configuration with a narrow end and a broad end, said locking cam member having a camming surface at said broad end and a locking cam member pivot axis near said narrow end, said locking cam member being adapted so as to be removably and pivotally mounted on said base plate, with said locking cam member pivot axis being aligned with one of said plurality of holes;a force application member having a narrow end and a broad end, said force application member having at least one force applying surface at one side of the broad end thereof and a force application member pivot axis near said narrow end, said force application member being adapted so as to be removably and pivotally mounted on said base plate, with said force application member pivot axis being aligned with one of said plurality of holes; andat least two pins adapted to be received in any two of said plurality of holes;wherein each of said locking cam member and said force application member has a handle member for effecting pivotal movement of each said member about its respective pivot axis;whereby a workpiece of malleable metal rod may be locked in place by being forced against two pins when they are received in two spaced apart holes, and said camming surface of said locking cam member is forced against the side of said workpiece remote from the side thereof which contacts said two spaced apart pins; andwhereby a workpiece may be bent by contacting the workpiece with said force applying surface of said force application member at a region of the workpiece which is near one of said two spaced apart pins but which is remote from the other of said spaced apart pins, and by causing pivotal movement of said force application member about its respective pivot axis by manipulation of the handle member thereof, so as to transfer bending force from said force application member to the workpiece through said force applying surface.
