ABSTRACT:
A tool for cutting a wire to length and then wrapping it around a terminal post includes an air motor driving through a planetary gear reduction to rotate a spindle, and a wire contacting bit rotated by the spindle. In order to develop sufficient torque to sever the wire at the bit, there is provided a member constrained to move helically with respect to the spindle housing, and the member is actuated by an air operated piston. A clutch between said member and the spindle disengages upon predetermined axial travel of said member to permit free turning of the spindle by the air motor to accomplish the wire wrapping operation. A spring returns said member to its initial position after the supply of air to the air motor and piston is cut off and the clutch automatically aligns the spindle and bit into initial position for insertion of another wire. One end of the spindle is supported within the bore of the inner race of a anti-friction bearing assembly in the housing. One end of a bit driving shaft is supported in the same bore and adjacent parts of the spindle and shaft are formed to provide a driving connection. The rotary bit is enclosed within a stationary sleeve and the wire is severed at the junction of an axial groove on the periphery of the bit and an axial groove on the stationary sleeve. Discharge of exhaust air from the tool is silenced by an oil collecting filter mounted within the handle of the tool.
