Abstract
Abstract Methods and apparatus for winding electrical conductor wire of moderate to heavy sizes on small and miniature toroidal cores utilizing a sliderless shuttle having storage coil of wire wound in a peripheral groove and held therein by a belt encircling a substantial part of the shuttle groove periphery. To permit mounting, loading and coil winding operations, the belt diverges from the shuttle periphery at the point where it passes through the toroidal core. Loading and winding rotation of the shuttle occur in the same direction, significantly minimizing flexure and bending distortion of the conductor wire as it is drawn from the shuttle groove.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A toroidal coil winding shuttle assembly incorporating A. a scarf-jointed ring-shaped shuttle adapted to be interlinked in relative rotatable engagement with a toroidal core and having a wire storage groove facing radially outward formed around its periphery, B. supporting means positioning the shuttle for relative rotational interlinked movement through the central aperture of the toroidal core, C. idler means supported adjacent to the interlinked position of the core, D. and a continuous and uninterrupted retainer belt having a substantial portion of its length encircling a substantial portion of the periphery of the shuttle overlying the wire storage groove, and diverging from said shuttle to pass along a path around said adjacent idler means, thence converging directly to rejoin said shuttle, with the interlinked toroidal core being supported for rotation at a point near the idler means between the converging and diverging portions of the retainer belt, E. and shuttle-engaging drive means providing driving torque causing said shuttle to rotate about its axis whereby the continuous, encircling retainer belt is retained thereon and tractively driven with and by the shuttle,
Claim 2
Dependent Claim
179 words
A toroidal coil winding shuttle assembly incorporating A. a scarf-jointed ring-shaped shuttle adapted to be interlinked in relative rotatable engagement with a toroidal core and having a wire storage groove facing radially outward formed around its periphery, B. supporting means positioning the shuttle for relative rotational interlinked movement through the central aperture of the toroidal core, C. idler means supported adjacent to the interlinked position of the core, D. and a continuous and uninterrupted retainer belt having a substantial portion of its length encircling a substantial portion of the periphery of the shuttle overlying the wire storage groove, and diverging from said shuttle to pass along a path around said adjacent idler means, thence converging directly to rejoin said shuttle, with the interlinked toroidal core being supported for rotation at a point near the idler means between the converging and diverging portions of the retainer belt, E. and shuttle-engaging drive means providing driving torque causing said shuttle to rotate about its axis whereby the continuous, encircling retainer belt is retained thereon and tractively driven with and by the shuttle,
Claim 3
Dependent Claim
54 words
The toroidal coil winding shuttle assembly defined in claim 1, wherein the supporting means comprises a plurality of rotatable sheaves supporting the shuttle by virtue of mutually counteracting radial forces, said drive means comprising at least one of said sheaves drivingly rotated to supply rotational torque as a tangential traction force to said shuttle.
Claim 4
Dependent Claim
20 words
The assembly defined in claim 2, wherein said sheaves are mounted for rotation on axes passing through the ring-shaped shuttle.
Claim 5
Dependent Claim
30 words
The assembly defined in claim 2, wherein said idler means are adjustably supported for variable positioning movement toward and away from said shuttle, providing tension adjustment for the retainer belt.
Claim 6
Dependent Claim
19 words
The toroidal coil winding shuttle assembly defined in claim 1, wherein the retainer belt is elastically resilient and deformable.
Claim 7
Independent Claim
178 words
The method of winding wire on a toroidal core comprising the steps of A. providing a scarf-jointed ring-shaped shuttle adapted to be interlinked in relative rotatable engagement with a toroidal core and having a wire storage groove facing radially outward formed around its periphery, B. supporting said shuttle for relative rotational movement interlinked through the central aperture of a toroidal core, C. supplying wire to said shuttle while simultaneously loading said wire into the groove of said shuttle by rotating said shuttle in a first direction, D. subsequently rotating said shuttle in the same first direction to wind said wire from said shuttle groove around said core, while E. encircling a portion of the peripheRy of said shuttle with a continuous retainer belt overlying the shuttle groove to retain the wire therein, F. diverting a portion of said retainer belt from the periphery of said shuttle at an approach point adjacent to said core, and G. returning the diverted portion of said belt directly to said shuttle at an return point on the opposite side of the core.
Claim 8
Independent Claim
178 words
The method of winding wire on a toroidal core comprising the steps of A. providing a scarf-jointed ring-shaped shuttle adapted to be interlinked in relative rotatable engagement with a toroidal core and having a wire storage groove facing radially outward formed around its periphery, B. supporting said shuttle for relative rotational movement interlinked through the central aperture of a toroidal core, C. supplying wire to said shuttle while simultaneously loading said wire into the groove of said shuttle by rotating said shuttle in a first direction, D. subsequently rotating said shuttle in the same first direction to wind said wire from said shuttle groove around said core, while E. encircling a portion of the peripheRy of said shuttle with a continuous retainer belt overlying the shuttle groove to retain the wire therein, F. diverting a portion of said retainer belt from the periphery of said shuttle at an approach point adjacent to said core, and G. returning the diverted portion of said belt directly to said shuttle at an return point on the opposite side of the core.
Claim 9
Dependent Claim
51 words
The toroidal coil winding method of claim 6, further including the step of securing a free end of a length of said wire, loaded into the groove of said shuttle, fixed in an initial turn on said toroidal core, before initiating winding rotation of said shuttle in the same first direction.
Claim 10
Dependent Claim
59 words
The toroidal coil winding method defined in claim 6 wherein the segment of wire delivered during each winding revolution of the shuttle in said first direction squeezes between the rim of the shuttle groove and the encircling overlying retainer belt by deforming the belt to force it away from the shuttle at successive points along their engaged peripheral portions.
Claim 11
Dependent Claim
24 words
The assembly defined in claim 1 wherein the continuous retainer belt travels along an uninflected path around said shuttle and around said idler means.
