Abstract

289,527. Moy, Ltd., E. F., and Newman, A. S. Jan. 27, 1927. Switches, actuating; latching. - A switch, group of switches, or other device requiring considerable pressure for actuation is operated by means of a small initial effort by causing the initial effort (that, for example, derived from air pressure) to propel a small ball o into a position where it is carried round by a continuously-rotating disc or drum r and in so doing swings out a pivoted lever t and thereby brings contacts k, i into engagement. The ball continues its travel and, guided by the spring v and the shaped plate 9 is finally restored to its original position opposite its blow hole l. The lever t in swinging outwards is retained by a spring catch x. Where a number of switches, as described, are used in line (as for example for controlling electric lamps in the printing of kinematograph film), each switch is operated when its corresponding ball is propelled by air pressure admitted to the corresponding tube by means of apertures in a moving band. When one switch has been closed, as described, it remains closed until the next ball is put in action, whereupon the act of closing the second switch causes the tail-piece w to lift the common latch x and release the switch first closed.
