Abstract
Abstract Terminal pins are formed one after another from a wire source (coil) by step-by-step hitch feeding, clamping, and pulling the wire apart to sever pins having tapered ends. A pin so formed is then positioned over a supporting die, the workpiece is placed between the pin and the die, and a plunger ejects the pin and forces it into the workpiece.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
167 words
Apparatus for continuously forming and inserting terminals in a work piece comprising a source of square wire, means to advance the wire in step by step relation, wire clamping jaws, means on said wire clamping jaws to clamp the wire, means to move one jaw away from the other while the wire is clamped, stretching and breaking the wire, forming square terminal pins having tapering points on the ends thereof, and being adaptEd to later wirewrapping, a pocket, means on the pocket to receive the severed pointed pins, means to move said pocket from the line of advance of the wire to an insertion station, a bottom die at the insertion station, means to move the bottom die in position to back up a work piece thereon, a plunger, said plunger being self-centering into said pocket, and means to move the plunger to eject the terminal pin from the pocket into the work piece simultaneously with the motion of the jaws to form the next succeeding pin.
Claim 2
Dependent Claim
167 words
