DIMMITT ROSS LOVE-TOY, OF NEW YORK, N. Y. ASSIGNOR '10 LOVE-TOY DEVELOPMENT CORPORATION, OF NEW YORK, N. Y., ACORPORATION OF NEW YORK.
INDUCTANCE COIL.
, Application filed August 14, 1924. Serial No. 732,021.
To all whom it'may concern:
Be. it known that I, DIMMrrr Ross Love-- Jot, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Inductance Coils, Of which the following is a complete speci fication, the particular novel feature of my invention being specifically stated in the annexed claims. I
It is well known that with the high frequencv currents used in radio, the accuracy of tuning afiorded by an inductance coil is impaired by the distributed capacity. Various methods for reducing the distributed capacity without diminishing the inductance have been devised, such for example as spider web, honeycomb, lattice weave and the like. Most of these winding expedients cannot well be used in winding a single layer cylindrical coil.
The object of in present invention-is to construct a single ayer. cylindrical winding with minimum distributed capacity without impairment 'of inductance. The invention comprises a helical coil in which successive sections are radially staggered in such a manner as to-separate the adjacent wires by a fixed distance except where theygcross from one radius'to another and to make the crossing in such away as to reduce the capacity efl'ect t0 the minimum.
In the accompanying drawing:
Figure 1 illustrates an axial view of a coil made according to my invention.
Figure 2 is a side elevation of the same.
Figure-3 is a detail of the coil.
i-Fi re 4. isa preferred form of coil in whic the periphery is cylindrical. instead of olygona Y 1 n 5 is an alternative construction. Reierring to Figures land 2 of the drawing, the wire 1,'preferably. enamel. insulated,
is cri ped. in such a manner that when woun long sections alternating with shorter sections, will form this into a polygonal cylinder the long sections forming the interior sides of the poly n and the short sections the exterior. en formed into a c linder-in this -way, insulating wrds 2 may extended through the interstices and tied in knots as at 3 to securely and locally lock -the assembled crossings in position. .The coil thus becomes quite rigid and self-sustaining, which permits it to be ture. Suitable flexible terminals may be attached to the end, as shown at 4. B- refer ence to Figure 3 it will be seen t at the wires cross eacsh other at a considerably greater an le than they would if they went crisscross iagonally direct from one crossing the next and that in between the crossings absolute parallelism at theprop'er minimum distance is maintained. In Figure 4 is .shown the same idea applied to aplace of the cord, the pins being supported on a circular ring 7. With such a frame,
ver thin wire may be wound onto coil' 8 an still attain the functions sought by the present invention.
While m invention in its broadest sense is ap licable 0th to the polygonal and the circu ar forms, no specific claim is made herein to the polygonal form as this will be made the subject of a separate application.

An inductance coil in the 'form of a' self-supported multi-turn helix of uniform diameter, 1n WlllCll successive turns cross each other from one radius to another and are parallel between crossings, and locking means composed of insulating material interposed in the angle of the crossings.
6. An inductance coil in the form of a self-supported multi-turn helixof uniform diameter, in'which adjacent sections of successive turns are. radially staggered and parallel with respect to each other, and insulating cords embracing the wires Where they cross. I
7. An inductance coil in the form of a self-supported multi-turn helix of uniform diameter, in which adjacent sections of sue; cessive turns are radially stag cred and par-. allelwith respect to each otl ier, and insulating cords extending between the parallel wires and embracing the assembled crossings where the Wires pass from one radius to another.
8.An inductance coil in the. form of a self-supported multi-turn helix of uniform 10. An inductance coil in the form of a self-supported cylindrical helix in which each of the adjacent turns are made up of circular arcs of alternately shorter and longer radii, those of shorter radii being adjacent those of longer radii in the adjacent turns.
11 An inductance coil in the form of a multi-turn helix in which adjacent sections of successive turns are radially staggered and parallel with respect to each other, and
"supporting means for said coil in the. form of a plate of insulating material inserted betweenthe inner and outer layers of one of the sections.
