Title: Improvements in or relating to machines for winding coils for electrical devices
IPC: H02K15/04
Filed: 1934-07-26
Abstract: 446,464. Coil - winding apparatus. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(General Motors Corporation; West Grand Boulevard, Detroit, Michigan, U.S.A.) July 26, 1934, No. 22411/35. Divided out of 446,415. [Class 35] Apparatus for winding coils of the type described in Specification 358,073 is provided with a winding head and wire guiding means formed to produce the required coil, the machine generally being identical with that described in Specification 446,415. The coil, Figs. 3 and 4, is of approximately rectangular shape, the wires lying parallel at the sides but crossing at the ends, so that the ends are constricted in the middle. To produce this coil a winding form is employed, which is shown in Fig. 34 with one side removed. The faces 136, 137 on which the sides of the coil are wound slant inwardly towards the edge where the first turn is to be placed. As the wires cross at the ends these edges are on opposite sides of the form and the two faces are approximately parallel. The ends of the form each consist of two faces 139, 140 and 138, 141 respectively. The faces 138, 139 slant towards the corners 502, 501, and the faces 140, 141 towards the corners 504, 503 respectively, so that opposite faces are approximately parallel. The side 143 of the form is curved inwardly at the ends to produce the necessary constriction. The tension of the wire passing over this form tends to produce a coil of the correct shape, but the wire is also positively guided by the device shown in Fig. 8, consisting of a pulley 278 carried on a bell-crank lever 276 the other arm of which bears on the edge of a cam disc 280. In the arrangement shown the coil consists of two wires, so the pulley 278 is provided with two grooves the appropriate distance apart. In order that the entering and leaving wires may be on opposite faces of the coil as well as on opposite sides, a groove is provided in the winding head which receives the first turn of the coil and allows it to proceed to the end face 139 from the high side of the face 136 instead of the low, the cam 280 being formed accordingly.

In a disc brake comprising an annular disc adapted to engage with a wheel or like member to be braked, a plurality of circumferentially-spaced friction pads on each side of the disc are adapted to frictionally engage the disc between them such that the friction pads are staggered radially across the braking surfaces of the disc to sweep substantially the entire braking surfaces of the disc in one revolution thereof. In the embodiment illustrated applied to a disc brake for aircraft, two axially spaced annular members 1 and 2 are adapted to rotate with the aircraft wheel by means of dogs 3 so that the annular members are axially slidable relative to the wheel. Braking is effected by means of a series of pads 21 which are housed in a substantially arcuate torque member 6 which is adapted to be bolted to a fixed portion of a wheel mounting and extends over about one half of the braking surface of the annular members and so shaped as to curve gradually inwards so that one end coincides with the outer periphery of the annular members 1 and 2 and the opposite end is approximately midway between the inner and outer peripheries of the annular members. Secured to the torque member 6 by bolts 10 is a further substantially arcuate member 8 of similar shape and having a radially extending portion 9 carrying fixed friction pads 24. A carrier plate 12 carrying pads of friction material 22 and 23 is located between the annular members 1 and 2 and secured to the rigid torque member but adapted for axial movement thereon. Bolted to the torque member 6 is a substantially arcuate housing 25 in which are situated fourteen fluid pressure actuated piston and cylinder units 28. In operation, when fluid pressure is applied to the pistons, the friction pads 21 are forced into frictional engagement with the annular member 1; continued movement of the pistons forcing the annular members 1 and 2 and the carrier plate 12 towards the radially extending member 9 whereby all the radially extended faces of the annuli are frictionally engaged to effect retardation thereof and of the wheel. The friction pads are restrained from rotation by means of pins 24a and the torque member 6 is provided with a support plate 6a to which an automatic braking device may be secured.

[Also in Group XXIX] The metal bottom of a gas holder is tested for leaks by smearing its inside surface with soap and creating above it a space of reduced pressure. In Fig. 1, a movable disc 4 is supported from a holder 1 or on stanchions 5 resting on the holder bottom 2. The disc 4 is provided with an ordinary seal (not shown) which prevents the passage of air or gas between the disc 4 and the holder shell 1. Air is withdrawn through a connection 6 to create the desired reduced pressure. A valve 7 prevents a desired pressure reduction from being exceeded. To test for weaknesses in the bottom 2, the latter is deflected a number of times to the position indicated by the dotted line 2a, the central stanchions 8 being first removed and the valve 7 adjusted to permit the necessary vacuum for such a deflection to be created. Fig. 2 illustrates the application of the invention to bell-shaped and telescopic holders. The outer shell 32 is connected in a gas tight manner to the bottom 31. A telescopic shell 33 bears through rollers 34 against the outer shell 32. The shell 33 has a hook-shaped upper periphery 35 which, on the bell 36 lifting, dips into a dipping cup 37 filled with water. The bell 36 bears against the telescopic shell 33 through rollers 38. A cylindrical ring 39 is mounted on the holder bottom 31. When the middle part of the holder is pumped empty, there is still an annular, waterfilled space 40 between the ring 39 and the holder shell 32, said water-filled space 40 forming a seal between the bell and the outer air. By a suitable adjustment of the water level in the annular space 40, the amount of vacuum for the test, obtainable under the bell 36, can be limited.
