Abstract
1,247,439. Time switches. HOLZERPATENT A.G. 10 March, 1969 [9 March, 1968 (2)], No. 12493/69. Heading H1N. A programme control device for automatic washing-machines has at least two cam wheels driven independently of one another by a single common motor via an eccentric drive including mutually phase-displaced driving pawls associated respectively with said wheels. Three cam wheels 2, 3, 4, respectively controlling reversal of the wash drum, programme switching, and time duration of operations, are loosely mounted on a shaft 1 and stepped by respective pawls 16, 15 and 14 oscillated by eccentrics 13, 12 and 11 on a common shaft 10 driven by a motor 7. Pawls 16 and 15 are controlled by the armatures of electromagnets 22 and 21. The three pawls operate out of phase, such that the motor 7 never has to stop more than one cam wheel at a time, and may be thrust-pawls (as shown) or traction pawls (Fig. 9, not shown) or a combination (Fig. 7, not shown). The pawls may be operated by a common eccentric, in which case they lie at different angles, or the pawls may be aligned and operated by differently phased eccentrics (Figs. 8 and 9, not shown). In the modifications of Figs. 10 and 11 (not shown), the cam wheels are not coaxial and the pawls are arranged accordingly. As shown, face cams on wheels 2, 3 and 4 control contact sets 25, 28 and 29 respectively while the periphery of a programme selector wheel 6, connected to the wheel 2, operates a contact set 36.
