Title: Improvements in electric motor starter switches
IPC: H01H9/26
Filed: 1945-12-11
Abstract: 600,732. Controllers ; control of A.C. motors. ERSKINE, HEAP, & CO., Ltd., and WATERHOUSE, F. Dec. 11, 1945, No. 24809/44. Drawings to Specification. [Class 38 (iii)] An A.C. motor starter of the kind using an auto-transformer and the Korndorfer scheme of connections is a vertical drum controller with two separate drums, the lower drum being operated by the upper through a coupling which is automatically disengaged just before the upper drum reaches its final position, to allow the lower to return to its " off " position. The upper drum, which has three contacts for engaging nine contact fingers, has a position in which it inserts an adjustable part of the autotransformer in the motor circuit as a choke and a final position in which it short-circuits the auto-transformer ; in an intermediate position between these two the lower drum bridges three fixed fingers to connect the transformer windings in star. A roller catch pivoted on an arm moving with the upper drum engages and drives a lower arm driving the lower drum until part of the catch rides up a fixed track and disengages the lever arm ; a spring returns the lower drum to the " off " position. A handle may drive the upper drum through a similar catch which can on occasion be disengaged to allow both drums to return independently of the handle in any handle position or at least after the transformer windings have been connected in star. Overload and low-voltage trips may be included.

Aug. 15, 1929, Flexible shafts. - Remote control mechanism for operating aircraft controls, electric switches, driving tools, &c., comprises a flexible member capable of transmitting push, pull and in some cases rotational movements, and a guiding member therefor which may be rigid or permanently bendable and which supports the flexible member through the intermediary of anti-friction balls. As shown in Fig. 5, on a flexible member 1, comprising a flexible shaft, cable or wire and preferably formed of a number of oppositely wound superposed layers of wire, is mounted a series of bead-like members 2 carrying in recesses balls 6 which bear on the guide tube 3. Each bead is formed from a rectangular sheet metal blank which is stamped with three ball recesses whereafter its ends are turned over to form bearing surfaces and it is stamped into tapering bead form. Alternatively the beads may be machined from the solid. Rotation and pull movements are transmitted by the cable 1, push movements by the beads. In a modification dispensing with the inner cable 1, adjacent beads are linked together by drive-transmitting rings. In a further modification, the beads are dispensed with and the inner cable is directly supported by balls, which are spaced by close-coiled springs, or by tapering conical members, or the balls may project through the guide tube and be retained by enclosing collars fitting the tube externally and having side gaps permitting insertion of the balls. As shown in Fig. 17, the guide member comprises a rigid or bendable central rod 40 on which are mounted ball-supported beads 41 linked together by drive-transmitting rings 47. A terminal arrangement for the guide tube form is shown in Fig. 9. The inner cable is passed through a threaded tubular member 49 on which screws a sleeve 50. The outer split end of member 49 is bound with wire 51 and soldered to the cable. A rod 55 forms the operating part and adjustment is provided by the sleeve 50 locked by a nut 52.

Abstract: 427,381. Variable speed generator systems. MILLES, G., 27, Einwanggasse, Vienna. Sept. 3, 1934, No. 25304. Convention date, Sept. 7, 1933. [Class 38 (iv)] [See also Group XXXVII] Automatic regulators.-A combined electromagnetic cut-out and regulator for use in motor-vehicle circuits has a common electromagnet and two armatures which are separated by an air gap but are bridged magnetically at one end, the armatures being arranged over the electromagnet, preferably one above the other so that one, the lower armature extends to just beyond the core and the other extends across the electromagnet to the magnetic yoke in order that the lines of force emerging from the magnet to the lower armature pass to the yoke through the upper armature. As shown in the Figure, the magnet core 1 terminates in an upper polepiece 7 below which is secured a non-magnetic plate 8 carrying the two armatures, 9, 10. The armatures are carried by leaf springs 11, 12 between which is clamped a magnetic bridging member 17. The lower armature 9 extends to just beyond the polepiece 7 and the upper armature extends across the electromagnet to a position above the end of the L-shaped magnetic yoke 2 so that lines of force pass along the lower armature, through the bridge 17, along the upper armature in the opposite direction and so to the return path in the yoke. Alternatively the two armatures may be similarly arranged in sideby-side formation. The upper armature performs the cut-out function controlling at contacts 14, 16 the charging connection between the dynamo 21 and battery 24, the lower armature 9 being the regulator armature and when attracted opens contacts 13, 15 and removes a short-circuit from the resistance 23 in the circuit of the dynamo field winding 22. The electromagnet is energized by a shunt winding 6 and a series winding 4, 5 in two sections the lower section carrying the current to the consuming devices 25 and both sections in series the charging current between dynamo and battery. Thus when a small battery is used in conjunction with a relatively high capacity installation, as for example in motor cycle sets, the life of the battery is lengthened.
