Filed: 1937-04-16
Abstract: 493,874. Automatic exchange switches. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SAXBY, R. N. April 16, 1937, No. 10955. [Class 40 (iv)] In a bi-directional switch of the kind described in Specification 391,151 in which normal release is effected by renewed operation of the rotary magnet whereas rotary release is produced by reoperation of the vertical magnet, the rotary detent being withdrawn by the vertical pawl, a guide member moves into the path of the vertical pawl as soon as rotary movement takes place in order to limit its stroke when operated to produce rotary release and thereby to facilitate its re-engagement with the vertical ratchet in the rotary normal position. As shown, the guide plate 14 and a lever 13 bearing against the upper part thereof are pivoted on a fixed shaft 15 and are held in the position shown in Fig. 3 during the vertical movement by the engagement of the lever 13 with the side of the vertical ratchet 19. When the rotary movement begins, however, the plate 14 and lever 13 are turned by a spring 16 into the position shown in Fig. 4, where they are stopped by the engagement of the plate 14 with the switch frame 10. If the vertical magnet is now energized, the vertical pawl 18 jams in a partially-operated position between the plate 14 and the front stop (not shown), so that it will easily re-engage the ratchet 19 in the rotary normal position. The lever 13 is restored by the ratchet 19, but the plate 14 remains locked until the vertical magnet is de-energized.

The current pulse of a D.C. impulse generator is initiated by the opening of a D.C. excitation circuit and controlled in magnitude and duration by the rate at which an air gap in the magnetic circuit is lengthened. The magnetic circuit comprises a fixed part 8, and a movable part 7 attached to pistons 9, 10, 11 by which the air gap may be varied, using hydraulic or pneumatic means controlled by a valve 18. As shown, the two cores 7, 8 have series connected coils 5 which are connected first to a D.C. source 1, to magnetize the cores (with the gap at a minimum) to saturation, and then to a load 2 and series resistor 4. At the instant of change-over the part 7 begins its opening movement. In an alternative construction (Fig. 2, not shown), separate windings, disposed around the air gaps, are provided for excitation and the load; the load windings may comprise several coils arranged for series or parallel connection to match varying applications. The pulse is terminated (in both constructions) by reversing the movement of part 7, when any surplus energy may be recovered by using the pistons to recompress the working fluid, and by supplying electrical energy to the excitation source.
