Abstract: A manually operated surgical steel rod cutter is disclosed. The rod cutter has a rod shearing tool head for cutting a rod when the rod is provided within aligned bores of two shearing subassemblies of the tool head. To cut the rod, an operator rotates an extendable handle to a substantially vertical position, inserts the rod in the tool head and rotates the handle to a substantially horizontal position. In order to increase the operator's shearing leverage, the handle can be extended from its retracted compact position by a linear pulling motion on a handle grip. The motion causes a handle extension that is adjacent and along the length of a first portion of the handle that has one end attached to the tool head, to extend from a sheath also attached to the first portion. The handle extension subsequently locks into an extended position when fully extended.

Abstract: When operating a system embodying the invention, the operator sits in a convenient position with his knees beneath the conveyor carrying the printed circuit boards. The tools for bending, cutting and otherwise operating on the components leads are located above the operator's lap, secured to the conveyor support structure. When a circuit board reaches a position in front of the operator, the board stops, the various bending, cutting or other special tools move into position, and the operator inserts the components the leads of which will extend beneath the circuit board in alignment with the tools. The leads of some components are bent by being forced against the sloped surface of a tool while the components are being inserted by the operator. The leads of others are bent and, if needed, cut by machine operated tools, actuated by the operator, after the components are inserted.

Abstract: The mechanism cuts component lead portions projecting from a support such as a circuit board though the leads may be spaced apart at different distances, and then clinches them against the board.

The clinching is done in opposite directions and normal to a line interconnecting the points from which the leads protrude thereby stabilizing the position of a component body.
