Abstract
Abstract In one aspect, the invention is a novel arrangement for applying forces tourns of a vertically extending helical coil which is wound about a support. The apparatus includes a first rigid member extending towards the turns. A second rigid member extends transversely from the end of the first and has a vertically extending face provided with a generally straight groove extending transversely of the turns. A longitudinal passage in the first member connects to the groove to form therewith a continuous guideway for rollable articles. A rigid lug longitudinally movable in the groove is provided with a projection which extends out of the groove and beneath the bottom of a selected turn of the coil. A train of rigid, rollable articles is disposed in the guideway inwardly of the lug. Means are provided for applying force to that end of the train which is relatively remote from the lug, to urge the latter against the bottom face of the selected turn. As a result, that turn is moved upward along the face of the support, establishing a selected spacing between that turn and the previously formed turn of the coil. When upward movement of the selected turn stops, the force applied to the lug immediately translates to a force which urges the above-mentioned grooved face against all of the formed turns, thus compressing them against the support. The above-mentioned first and second members are swingably mounted so that they can be temporarily moved out of the winding path, thus permitting continuous winding.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
230 words
Apparatus for applying force to turns of a helical coil wound about a rotatable support, comprising: a rigid member having an axis, said member being mounted to rotate with said support and being arcuately movable about an axis parallel with the axis of said member, said member having a face confronting said turns for compressing said turns against said support, said face being formed with a groove extending transversely of said turns, a longitudinally extending passage in said member connected to said groove to form therewith a continuous guideway for rollable articles, a rigid lug mounted in said groove for longitudinal movement therein and having a projection which extends laterally from said groove, said projection having an end face confronting said hub and having a lateral face confronting a face of the last-formed turn of said coil, a train of rollable articles in said guideway inwardly of said lug for movement therein, and means for applying force to the end of said train relatively remote from said lug to urge said lateral face thereof against said face of the last-formed turn of said coil to displace said turn along the face of said support; the force so applied to said lug being translated, up cessation of the displacement of said turn, to a force which urges said face of said member against said turns to compress them against said support.
Claim 2
Dependent Claim
230 words
Apparatus for applying force to turns of a helical coil wound about a rotatable support, comprising: a rigid member having an axis, said member being mounted to rotate with said support and being arcuately movable about an axis parallel with the axis of said member, said member having a face confronting said turns for compressing said turns against said support, said face being formed with a groove extending transversely of said turns, a longitudinally extending passage in said member connected to said groove to form therewith a continuous guideway for rollable articles, a rigid lug mounted in said groove for longitudinal movement therein and having a projection which extends laterally from said groove, said projection having an end face confronting said hub and having a lateral face confronting a face of the last-formed turn of said coil, a train of rollable articles in said guideway inwardly of said lug for movement therein, and means for applying force to the end of said train relatively remote from said lug to urge said lateral face thereof against said face of the last-formed turn of said coil to displace said turn along the face of said support; the force so applied to said lug being translated, up cessation of the displacement of said turn, to a force which urges said face of said member against said turns to compress them against said support.
Claim 3
Dependent Claim
158 words
In combination with coil-forming apparatus including a vertically disposed coil-support: a horizontally movable rigid member mounted adjacent to said support, said member comprising a horizontally extending first arm affixed to the central section of a vertically extending second arm, the second arm having a face which confronts said support and has a vertical groove therein, a rigid lug slidably mounted in said groove, said lug having a projection extending out of said groove and toward said support, a longitudinally extending passage in the first arm, said passage being connected to said groove by a generally S-shaped passageway; said passage, groove, and passageway forming a continuous guideway, a movable train of rigid articles disposed in said guideway for transmitting force to said lug; and means for applying force to said train to effect movement of said lug in said groove; said force translating, upon cessation of movement of said lug, to a force urging said member toward said support.
Claim 4
Dependent Claim
158 words
In combination with coil-forming apparatus including a vertically disposed coil-support: a horizontally movable rigid member mounted adjacent to said support, said member comprising a horizontally extending first arm affixed to the central section of a vertically extending second arm, the second arm having a face which confronts said support and has a vertical groove therein, a rigid lug slidably mounted in said groove, said lug having a projection extending out of said groove and toward said support, a longitudinally extending passage in the first arm, said passage being connected to said groove by a generally S-shaped passageway; said passage, groove, and passageway forming a continuous guideway, a movable train of rigid articles disposed in said guideway for transmitting force to said lug; and means for applying force to said train to effect movement of said lug in said groove; said force translating, upon cessation of movement of said lug, to a force urging said member toward said support.
