Abstract
Abstract The inner commutator shield of a double flier armature winding machine is provided with notches having edges for severing wire leads hooked around commutator tangs closely adjacent the tangs. Two embodiments are illustrated, one wherein the armature is rotated to sever the wires and the other wherein the inner shield is rotated. In both cases finish wires are cut by first rotating the armature to position selected tangs closely adjacent the notches after the wires are first hooked to the selected tangs. The wire segments between the tangs and the fliers are gripped by clamps prior to the severing of the finish wires. The mechanism described may also be used for the severing of start wires.

Claim 1
Independent Claim
220 words
For use with a flier-type armature winder of the type having a commutator shield device including a notched inner shield and means for covering the inner shield and commutator tangs during the winding of coils of wire by a flier, a method for connecting a finish wire of an armature being wound to a selected commutator tang and for severing the finish wire comprising the steps of: 1. locating a notch in said inner shield in overlying relation to said commutator and angularly spaced from said selected tang, 2. at the termination of the winding of the last coil by said flier, exposing said selected tang, 3. rotating said flier in a direction opposite to its direction of rotation when winding coils, thereby to hook the wire leading from said flier over said selected tang, 4. bending the portion of said wire between said selected tang and said flier toward the armature core, 5. rotating said armature core and said commutator to position said selected tang adjacent said notch, 6. positioning said bent portion of wire in said notch, 7. relatively rotating the armature and said inner shield to cause said wire to be severed by an edge of said notch, and 8. prior to the severing of said wire clamping said wire between said selected tang and said flier.
