Title: Improvements in or relating to electrical coils and to the manufacture thereof
IPC: H01F17/02
Filed: 1919-12-11
Abstract: 159,997. Wade, H., (Coto-Coil Co.). Dec. 11, 1919. Solenoids.-To reduce their capacity, electric coils are wound in widely-spaced helical turns, disposed at a substantial angle to the axis of the coil, and adjacent turns in adjacent layers cross each other at large angles, thereby forming a multitude of air cells extending substantially radially and laterally through the coil. The - coils can be produced by machine-winding, and their mechanical structure is such that end heads or flanges to support the windings are not required. In the diagrams, a coil is shown wound with a " half-wind " and the winding mandrel makes approximately half a revolution to one traverse of the wire guide corresponding to the width of the coil to be wound, which is then reversed. As the wire being wound reaches the end of its traverse and starts back in the opposite direction, a bend or " knuckle " k is formed. These " knuckles " align in a plane at right-angles to the coil and forms its flat ends, and the rotation of the winding-mandrel makes a " gain " over the traverse of the wire-guide so that the reversing point of each successive turn is slightly in advance of that of the last laid turn, and a spaced winding is secured. The " hnuckles " k in successive turns in successive layers instead of coinciding in a radial plane x-x are disposed in a plane y-y, the "knuckles" k advancing slightly round the circumference as the winding continues in the direction of the arrow z. Reference has been directed by the Comptroller to Specification 141,344.
