Abstract
Abstract The apparatus for quickly, easily and accurately varying the configuration and plane of the elliptical path of the needle of a semi-automatic stator-coil winding machine. The machine includes a rotary movement section and an elliptical movement section arranged in cooperation with one another such that a rotary movement is translated into an elliptical movement to drive a wire-carrying needle about the perimeter of a stator-coil and thereby wind it. By varying the elliptical path of the needle, the apparatus of this invention substantially improves the capability of the machine to wind coils of different configurations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
A coil winding machine comprising a rotary movement section, an elliptical movement section, said elliptical movement section including a center shaft, means coupling said elliptical movement section to said rotary movement section for translation of rotary movement into elliptical movement, said elliptical movement section including a needle bar, a coil winding needle connected to said needle bar, said needle bar pivotally mounted on said center shaft so as to be movable by said elliptical section, a cam means rotatably mounted on said center shaft and engaging said needle bar so that relative movement of said cam means to said center shaft varies the position of said needle relative to said center shaft, adjusting means movably interconnecting said rotary movement section and said elliptical movement section whereby the stroke of said needle and movement of both sections is varied, carriage means connected to said rotary and elliptical movement section, at least one of said sections being movable thereon so as to move said one section relative to the other and thereby vary the swing of said needle when in operation.
Claim 2
Dependent Claim
179 words
A coil winding machine comprising a rotary movement section, an elliptical movement section, said elliptical movement section including a center shaft, means coupling said elliptical movement section to said rotary movement section for translation of rotary movement into elliptical movement, said elliptical movement section including a needle bar, a coil winding needle connected to said needle bar, said needle bar pivotally mounted on said center shaft so as to be movable by said elliptical section, a cam means rotatably mounted on said center shaft and engaging said needle bar so that relative movement of said cam means to said center shaft varies the position of said needle relative to said center shaft, adjusting means movably interconnecting said rotary movement section and said elliptical movement section whereby the stroke of said needle and movement of both sections is varied, carriage means connected to said rotary and elliptical movement section, at least one of said sections being movable thereon so as to move said one section relative to the other and thereby vary the swing of said needle when in operation.
Claim 3
Dependent Claim
48 words
A coil winding machine as in claim 1 further comprising a cam adjusting means fixedly positioned on said machine and oriented to periodically engage said cam means, whereby said cam means is caused to periodically rotate relative to said center shaft upon engagement with said cam adjusting means.
Claim 4
Dependent Claim
69 words
A coil winding machine as in claim 1 wherein said cam means includes a cam surface having a predetermined configuration, said needle bar having at least one end thereof positioned in movable engagement with said cam surface; said cam means fixedly mounted on said shaft in a co-linear direction relative to the longitudinal axis of said center shaft and rotationally movable about the longitudinal axis of said center shaft.
Claim 5
Dependent Claim
47 words
A coil winding machine as in claim 1 wherein said needle is mounted on the extremity of said needle bar opposite to said cam means whereby movement of said cam means relative to said needle bar varies the position of said needle relative to said center shaft.
Claim 6
Dependent Claim
63 words
A coil winding machine as in claim 4 further comprising biasing means interconnected to said center shaft and positioned in biasing engagement with said cam means, said cam means including a cam surface disposed in operative engagement with said needle bar and having a predetermined configuration, whereby the configuration of said surface determines the position of said needle relative to said center shaft.
Claim 7
Dependent Claim
40 words
A coil winding machine as in claim 1 wherein said carriage means comprises a pair of parallel bars, said rotary section slidably mounted for movement on said bars relative to the elliptical movement section, and means for moving said carriage.
Claim 8
Dependent Claim
29 words
A coil-winding machine of claim 6 wherein the means for moving the carriage comprises a rod threaded to the frame and attached to a portion of the rotary section.
Claim 9
Dependent Claim
38 words
A coil winding machine as in claim 7 wherein the adjustment means comprising a slotted clevis on which a universal joint is supported, said clevis being bolted to the rotary movement section by a bolt through said slot.
