Abstract
Abstract A wire-stripping apparatus is disclosed herein having a cutter adapted to sever insulation from the ends of a pair of separate wires preparatory to removal of the severed insulation from each of the wires. Also, the cutter severs a predetermined length of wire from a coil stored on a reel. The apparatus includes a gripping means having a pair of cooperating grippers adapted to clamp about the insulated wires so that the wires are positively retained during the cutting and stripping procedure. Linkage means, including an eccentric pivot connection, actuates the pair of grippers in response to control means for automatically clamping and releasing the pair of wires simultaneously.

Claim 1
Independent Claim
287 words
In a wire-stripping and cutting apparatus having a cutting means for severing a plurality of wires into predetermined lengths and for cutting insulation from the ends of the wire lengths, the improvement which comprises: a gripping means operably carried on said apparatus having a pair of opposing clamping faces separated by said plurality of wires and being settable in an open position out of contact with said wires and in a closed position to clamp and hold said wires in fixed spaced-apart parallel relationship; means carried on said apparatus for actuating said gripping means clamping faces into either of said open or said closed positions; said clamping faces are broad, flat surfaces in a parallel relationshIp with respect to each other; means included in said gripping means for adjusting a selected one of said clamping faces with respect to the other of said clamping faces to maintain said parallel relationship; said gripping means further includes a support block and a pair of bellcranks pivotally carried on said block; each of said bellcranks being formed to provide one of said clamping faces; means pivotally interconnecting said bellcranks together in driving relationship to effect positioning of said clamping faces between said open and said closed positions in response to said actuating means; said adjusting means comprises an eccentric pivot connection coupling said selected bellcrank to said support block; means for rotating said eccentric pivot connection relative to said block so that said selected bellcrank-clamping face may be selectively moved with respect to the other bellcrank-clamping face; and said interconnecting means comprises a pair of quadrant members having intermeshed peripheral teeth wherein a selected one of said quadrant members drives the other quadrant member in response to said actuating means.

In a wire-stripping and cutting apparatus having a cutting means for severing a plurality of wires into predetermined lengths and for cutting insulation from the ends of the wire lengths, the improvement which comprises: a gripping means operably carried on said apparatus having a pair of opposing clamping faces separated by said plurality of wires and being settable in an open position out of contact with said wires and in a closed position to clamp and hold said wires in fixed spaced-apart parallel relationship; means carried on said apparatus for actuating said gripping means clamping faces into either of said open or said closed positions; said clamping faces are broad, flat surfaces in a parallel relationshIp with respect to each other; means included in said gripping means for adjusting a selected one of said clamping faces with respect to the other of said clamping faces to maintain said parallel relationship; said gripping means further includes a support block and a pair of bellcranks pivotally carried on said block; each of said bellcranks being formed to provide one of said clamping faces; means pivotally interconnecting said bellcranks together in driving relationship to effect positioning of said clamping faces between said open and said closed positions in response to said actuating means; said adjusting means comprises an eccentric pivot connection coupling said selected bellcrank to said support block; means for rotating said eccentric pivot connection relative to said block so that said selected bellcrank-clamping face may be selectively moved with respect to the other bellcrank-clamping face; and said interconnecting means comprises a pair of quadrant members having intermeshed peripheral teeth wherein a selected one of said quadrant members drives the other quadrant member in response to said actuating means.
Claim 3
Dependent Claim
205 words
A gripping means for holding a plurality of wires in parallel spaced-apart relationship comprising: a support block; a pair of bellcranks having flat, parallel spaced-apart and opposing clamping faces defining a space therebetween to receive the plurality of wires; mounting links pivotally connecting the ends of said bellcranks to said support block; drive means rotatably carried on said support block and pivotally coupled to said bellcranks for positioning said bellcranks whereby their respective clamping faces are moved between an open position and a closed position to clamp the wires; actuator means connected to a selected one of said bellcranks for actuating said drive means; said drive means includes a pair of quadrant members having intermeshed peripheral teeth in driving relationship; each quadrant member having an integrally formed extension pivotally connected to a respective bellcrank midway between its opposite ends; said mounting link connecting said selected bellcrank to said support block includes an eccentric pivot connection adapted to be rotated for positioning said clamping faces with respect to each other; and adjustment means operably connecting said selected bellcrank to said support block via its associated mounting link for adjusting said clamping face of said selected bellcrank with respect to said clamping face of the other bellcrank.
