Power operated wire stripper
First Claim
Patent Images
1. A power operated stripper for removing insulation from the ends of electric wires, comprising:
- a housing;
a power cylinder connected to one end of the housing, a piston in the power cylinder, and a piston rod connected to the piston and extending therefrom in a defined direction into the housing;
first and second levers pivotally mounted on a common pivot on the other end of the housing, extending in the defined direction away from the housing and arranged to perform a pivoted opening and closing action relative to each other in a direction generally at right angles to the defined direction;
a pair of clamping jaws on one lever and a pair of stripping jaws on the other constructed to open and close on an insulated wire placed between them;
first and second links each having an opening for pivotally mounting the links on said common pivot, the first and second links also each having a downward extension which joins a cam portion, the cam portions defining cam slots which extend at oppositely-directed angles to the defined direction, the links being mounted one on top of the other so that the cam slots overlap one another;
third and fourth links pivotally connecting the first and second links to the first and second levers; and
a cam roller connected to the piston rod and disposed in both cam slots such that linear translation of the piston causes pivoting of the first and second links about the common pivot, thereby causing the third and fourth links to open and close the jaws and to open and close the levers upon operation of the power cylinder.
