Abstract
Abstract An attachment for a wire stripping gun whereby jumper wires are automatically advanced, stripped and cut. A pneumatically controlled transfer unit including two pistons and clamping jaws advances wire from a supply reel to a cutting die actuated by a pneumatically controlled piston. Pneumatically controlled pivoted spring fingers grip the wire advanced through the cutting die and position it adjacent the gun whereby the wire may be stripped and wrapped.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
Automatic wire stripping and wrapping apparatus comprising: a wire stripping and wrapping gun including a winding mandrel, a stripper and a wrapping sleeve; wire transfer means connected to said gun; selectively operable wire cutting means coupled to said transfer means for receiving wire therefrom and severing said wire; and gripping means coupled to said gun adapted to grip the wire transmitted by said cutting means and to position said wire for operation thereon by said gun; said transfer means including: a first housing; a first piston positioned within said first housing; clamping means positioned in said first housing and responsive to the movement in a first direction of said piston for firmly clamping said wire; and a second piston positioned within said first housing adapted to move in said first direction said clamping means and said clamped wire said first direction.
Claim 2
Dependent Claim
141 words
Automatic wire stripping and wrapping apparatus comprising: a wire stripping and wrapping gun including a winding mandrel, a stripper and a wrapping sleeve; wire transfer means connected to said gun; selectively operable wire cutting means coupled to said transfer means for receiving wire therefrom and severing said wire; and gripping means coupled to said gun adapted to grip the wire transmitted by said cutting means and to position said wire for operation thereon by said gun; said transfer means including: a first housing; a first piston positioned within said first housing; clamping means positioned in said first housing and responsive to the movement in a first direction of said piston for firmly clamping said wire; and a second piston positioned within said first housing adapted to move in said first direction said clamping means and said clamped wire said first direction.
Claim 3
Dependent Claim
56 words
Automatic wire stripping and wrapping apparatus, according to claim 1, wherein said wire cutting means comprises: a second housing; a cutting die positioned in said second housing adapted to sever said wire upon activation thereof; and a third piston positioned in said second housing adapted to move in said first direction to activate said cutting die.
Claim 4
Dependent Claim
86 words
Automatic wire stripping and wrapping apparatus, according to claim 2, wherein said gripping means comprises: a third housing; spring fingers positoned in said third housing and adapted to extend therefrom for gripping said wire; a fourth piston positioned in said third housing adapted to urge said spring fingers out of said third housing; and pivoted position means coupled to said gun and adapted to move said third housing toward said cutting means to enable said spring fingers to grip the wire transmitted by said cutting means.
