Abstract
729,406. Electromagnetic switches; interlocking switches. ARROW ELECTRIC SWITCHES, Ltd. Sept. 18, 1953 [Sept. 30, 1952], No. 25799/53. Class 38 (5). Two switches, particularly two electromagnetic relays each having a pivoted lever, are interconnected so that one lever can only move to the attracted position when the other lever has moved fully to the unattracted position. As shown, levers 20, 40 are pivoted at 21, 41 and are connected at their outer ends to the plungers 10a, 12a of the relays. Between the inner ends of the levers is located a member 54 pivoted on a pin 38 and having a roller 56 which is engaged by the end of either lever when that lever, e.g. 20, is moved from the Fig. 2 to the Fig. 3 position, so that the roller is moved beneath the end of the other lever to prevent movement thereof. The adjacent ends of the levers are each curved on a radius concentric with the axis 21 or 41 of the lever so that the roller 56 is not released until the lever returns fully to the Fig. 2 position. In order merely to prevent movement of one lever whilst the other lever is in the attracted position, a bell-crank lever 60 may be arranged on a pin 39, rollers 66, 68 on the ends of the lever co-operating with notches 25, 45 in the levers 20, 40. Operation of one lever, e.g. 20, to the Fig. 5 position tilts the lever 60 to obstruct the other lever, and operation of lever 40 from this position assists the return of lever 20 to its Fig. 4 position. Lever 54 may remain in position or may be removed whilst lever 60 is in use.
