Abstract
Abstract A double loop of wire is formed about a commutator hook before an armature coil is wound, the double loop gripping the hook with sufficient strength to withstand the force generated when the first coil is being wound tending to pull the wire away from the hook. While forming the double loop, the free end of the wire is clamped, the clamped wire portion being severed after the double loop is formed. During the forming of at least the second loop, the wire is positively guided into hooking relation to the commutator hook.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
193 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core with an armature winding machine of the type having at least one rotating flier for laying wire into pairs of armature slots to form coils therein, the steps of holding one end of the wire to be used in winding coils in fixed relation to an armature to be wound and, while continuing to hold the wire, forming by said armature winding machine a first loop of wire about a preselected commutator hook by relatively moving said armature and the wire extending between said one end and said flier, said first loop being formed by hooking the wire about said commutator hook and then continuing the wire on around said hook, thereafter again hooking by said armature winding machine the wire about said commutator hook by relatively moving said armature and the wire extending between said one end and said flier while continuing to hold the end of said wire in fixed relation to the armature, and thereafter releasing the said end of wire adjacent said hook.
Claim 2
Dependent Claim
193 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core with an armature winding machine of the type having at least one rotating flier for laying wire into pairs of armature slots to form coils therein, the steps of holding one end of the wire to be used in winding coils in fixed relation to an armature to be wound and, while continuing to hold the wire, forming by said armature winding machine a first loop of wire about a preselected commutator hook by relatively moving said armature and the wire extending between said one end and said flier, said first loop being formed by hooking the wire about said commutator hook and then continuing the wire on around said hook, thereafter again hooking by said armature winding machine the wire about said commutator hook by relatively moving said armature and the wire extending between said one end and said flier while continuing to hold the end of said wire in fixed relation to the armature, and thereafter releasing the said end of wire adjacent said hook.
Claim 3
Dependent Claim
193 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core with an armature winding machine of the type having at least one rotating flier for laying wire into pairs of armature slots to form coils therein, the steps of holding one end of the wire to be used in winding coils in fixed relation to an armature to be wound and, while continuing to hold the wire, forming by said armature winding machine a first loop of wire about a preselected commutator hook by relatively moving said armature and the wire extending between said one end and said flier, said first loop being formed by hooking the wire about said commutator hook and then continuing the wire on around said hook, thereafter again hooking by said armature winding machine the wire about said commutator hook by relatively moving said armature and the wire extending between said one end and said flier while continuing to hold the end of said wire in fixed relation to the armature, and thereafter releasing the said end of wire adjacent said hook.
Claim 4
Dependent Claim
193 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core with an armature winding machine of the type having at least one rotating flier for laying wire into pairs of armature slots to form coils therein, the steps of holding one end of the wire to be used in winding coils in fixed relation to an armature to be wound and, while continuing to hold the wire, forming by said armature winding machine a first loop of wire about a preselected commutator hook by relatively moving said armature and the wire extending between said one end and said flier, said first loop being formed by hooking the wire about said commutator hook and then continuing the wire on around said hook, thereafter again hooking by said armature winding machine the wire about said commutator hook by relatively moving said armature and the wire extending between said one end and said flier while continuing to hold the end of said wire in fixed relation to the armature, and thereafter releasing the said end of wire adjacent said hook.
Claim 5
Dependent Claim
33 words
The method of claim 1 wherein said wire is hooked about said commutator hook by rotation of a flier and wherein said wire is positively guided into hooking relation with said commutator hook.
Claim 6
Dependent Claim
39 words
The method of claim 1 further including the step of continuing to loop said wire about said commutator hook thereby to form two complete loops about said commutator hook before releasing the end of said wire adjacent said hook.
Claim 7
Dependent Claim
29 words
The method of claim 1 wherein said wire is released by severing the end of the wire between the point at which it is held and said commutator hook.
Claim 8
Dependent Claim
98 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core utilizing a flier type winding machine, the steps of holding the free end of a wire from a flier in fixed relation to an armature to be wound and forming by said flier type winding machine two loops of the wire about a preselected commutator hook by relatively moving said armature and the wire extending between said free end and said flier prior to the winding of a coil by said flier.
Claim 9
Dependent Claim
98 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core utilizing a flier type winding machine, the steps of holding the free end of a wire from a flier in fixed relation to an armature to be wound and forming by said flier type winding machine two loops of the wire about a preselected commutator hook by relatively moving said armature and the wire extending between said free end and said flier prior to the winding of a coil by said flier.
Claim 10
Dependent Claim
144 words
In a method of winding armatures of the type having a slotted armature core and a commutator with hooks on the end thereof confronting said core with a flier type winder, the steps of clamping the free end of wire leading from the flier in a fixed position relative to the armature to be wound, positioning the flier at a location wherein a section of the wire extends from the clamped portion thereof to the flier between the armature core and the commutator, exposing a preselected commutator hook, rotating the flier in a direction to hook said section of wire about said preselected commutator hook, shielding said preselected hook, rotating the flier to loop the section of wire about said preselected commutator hook, again exposing said preselected hook, and rotating said flier to again hook said section of wire about said preselected commutator hook.
Claim 11
