Abstract

The selector disc (21) with cut outs corresponding to the distance to be moved by the contact arms (7, 8) is rotated through the required angle by the primary drive shaft (37, 36). In moving the disc carries with it spring loaded driving discs (19, 20) whose springs it charges. Reverse movement of these discs is prevented by latches which engage with teeth inside the discs. When the selector disc has moved through the prescribed angle a projection trips the latch and the stored energy in the spring is released resulting in an impulse drive to the shaft connected to the contacts (7, 8) through a set of sprocket wheels (15, 16). Two sets of latches are provided in each driving disc, one for each direction of rotation. Each driving disc controls one contact, and the discs are interlinked to give the required contact sequence. Single contact drives are also possible with the arrangement.
