Abstract
Abstract Procedures are described for wave winding armatures to be used in dynamoelectric machines having four or more poles utilizing flier type armature winding machines. After the winding of each coil or pair of coils, the armature is rotated through 360 electrical degrees plus or minus the angle between adjacent armature slots to position the armature for the winding of the next coil or pair of coils. Intermediate the winding of coils by the same flier the lead wire connections are made to the commutator by looping the lead wires about hooks projecting from the commutator. All coils are wound with the flier or fliers rotating in the same direction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
In a method of wave winding armatures having four or more poles using a flier type armature winding machine, the improvement wherein coils successively wound by a flier are wound by the flier rotating in the same direction for each coil, the armature is rotated through 360 electrical degrees plus or minus the angle between adjacent coil receiving slots between the winding of the successively wound coils, and the lead wires are extended around the armature shaft from the finish of one coil past the start of the same coil to the start of the next succeeding coil whereupon the lead wires for each coil cross over one another, and an intermediate portion of each wire lead is looped about a commutator hook.
Claim 2
Dependent Claim
123 words
In a method of wave winding armatures having four or more poles using a flier type armature winding machine, the improvement wherein coils successively wound by a flier are wound by the flier rotating in the same direction for each coil, the armature is rotated through 360 electrical degrees plus or minus the angle between adjacent coil receiving slots between the winding of the successively wound coils, and the lead wires are extended around the armature shaft from the finish of one coil past the start of the same coil to the start of the next succeeding coil whereupon the lead wires for each coil cross over one another, and an intermediate portion of each wire lead is looped about a commutator hook.
Claim 3
Dependent Claim
149 words
In a method of wave winding armature having four or more poles using a flier type armature winding machine having a right hand flier and a left hand flier comprising the steps of supporting an armature between the fliers, winding a pair of coils, one with each of said right and left hand fliers, rotating the armature about its axis through a total distance equal to 360 electrical degrees plus or minus the angle between adjacent armature slots, winding another pair of coils with said fliers rotated in the same direction through which they were rotated during the winding of the first pair of coils, and connecting the lead wires connected between the first coil and the second coil wound by each flier to commutator bars between the time of the winding of the first mentioned pair of coils and the winding of the second mentioned pair of coils.
Claim 4
Dependent Claim
149 words
In a method of wave winding armature having four or more poles using a flier type armature winding machine having a right hand flier and a left hand flier comprising the steps of supporting an armature between the fliers, winding a pair of coils, one with each of said right and left hand fliers, rotating the armature about its axis through a total distance equal to 360 electrical degrees plus or minus the angle between adjacent armature slots, winding another pair of coils with said fliers rotated in the same direction through which they were rotated during the winding of the first pair of coils, and connecting the lead wires connected between the first coil and the second coil wound by each flier to commutator bars between the time of the winding of the first mentioned pair of coils and the winding of the second mentioned pair of coils.
Claim 5
Dependent Claim
28 words
The method of claim 2 wherein said lead wires are connected to said commutator bars by looping said lead wires completely around commutator hooks projecting from said bars.
