Title: Improvements relating to automatic switches of the kind used in telephone systems
IPC: H01H63/22
Filed: 1946-04-05
Abstract: 610,289. Reciprocating machines. SIEMENS BROS., & CO., Ltd., and BRYAN, E. A. April 5, 1946, No. 10620. [Class 35] [Also in Group XXXIX] A motor for a step-by-step switch comprises a wound stator and a spring-restored unwound rotor tapered so as to ensure that the torque during the forward motion has a minimum value at the end or operated position. When the stator 3 is energized by the coil 30, Figs. 1, 2, the rotor 1 moves clockwise, against the tension of the restoring spring 14, its pin 6 moving between the stops 4, 5 which are adjustable by the screws 8, 9. The desired torque characteristic is obtained by shaping the rotor armature so that it tapers from its trailing to its leading edge. Coupling between the rotor spindle 7 and the driving spindle 15 comprises a tightly coiled helical spring 16 fixed to the rotor spindle and arranged to tighten around and so rotate the driving spindle for one direction of rotation of the rotor and to slacken and slip over the driving spindle in the other direction. The switch itself is provided with a simple non-return pawl and ratchet. The rotor armature may be built'up of laminations, Figs. 8, 9, 10 (not shown). The rotor armature may be broadened at its leading edge to provide increased initial torque. In a modification, Figs. 11, 12 (not shown), a rotor having tapered teeth on its inner and outer faces at the same angular position rotates between two stator elements having correspondingly positioned untapered teeth.

Filed: 1932-04-16
Abstract: 399,881. Master control of D.C. motors. HIGGS, G. R., Lintrathen, Kirriemuir, Angus, PRENTICE, T. A., 536, Sandyhills Road, Glasgow, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. April 16, 1932, No. 10952. [Class 38 (iii).] The control circuits of vehicle motors 1, 2, Fig. 1, accelerated by resistances r<1>, r<2> under the control of an accelerating controller A.C., Fig. 2, and changed by closed circuit transition from series to parallel connection by combination switches J, JR, S, P, G, under control of a combination controller CC, are so arranged that by operation of the combination controller from a parallel to a series position, in conjunction with the operation of an auxiliary switch TS, the combination switches for parallel connection are opened, and those for series connection closed, even though the accelerating controller is maintained in the same operative position which it occupied immediately prior to the said operation of the combination controller. As shown in Fig. 2, operation of the switch TS, which is preferably of the pushbutton type, de-energizes the main switch LS1 which by means of its interlock de-energizes the switches P, G, J, and these latter switches in opening complete circuits for the switches S, JR, so that with the combination controller in its series position, and the switch TS released, switch LS1 again closes to connect the motors is series. During this time the accelerating controller A.C. may be left in the same position, so that the amount of resistance in circuit with the motors in series is the same as it was previous to the change. A control system for four motors arranged for series, series-parallel, and parallel control, and including a modification of the invention, is described with reference to Figs. 4 and 5 (not shown). In this system an overload relay is provided to open the resistance contactors, and the line switches on overload, and the contacts of the switch T.S. are included in series with those of the overload relay, so that, when operated, it simulates an overload to open the main switches. In a further modification, Fig. 6 (not shown), no auxiliary switch TS is provided but movement of the combination controller alone is effective to open retaining circuits for the combination switches.
