Abstract

1,009,272. Time switches. BUSCH-JAEGER DURENER METALLWERKE A.G. May 10, 1963 [May 11, 1962], No. 18660/63. Heading H2B. A time switch for an automatic washing machine which comprises a single synchronous motor driving change-over contacts (to oscillate the washing drum) and also a stepping programme device, is arranged such that the stepping device is stopped while water is being heated and automatically restarted upon a pre-selected temperature being reached but the change-over contacts continue to be driven during the heating period. The motor drives a shaft 6a which operates change-over contacts 7 by means of a cam 8 and also steps programming cams 12 (Fig. 1) by means of a cam 10, pawl 9 and ratchet wheel 11 (Fig. 2). The cams 12 operate contact arms 13 and a programme is selected by a knob (Fig. 4, not shown) which sets cams 3 controlling the positions of contact arms 14 co-operating with contact arms 13. When the water is to be heated a gap 11b on ratchet wheel 11 is engaged by pawl 9 and the cams 12 cease to step, but the motor and contacts 7 continue to operate. In arriving at this dwell period a pin 19 on a ratchet wheel 11 urges a lever 18 to compress spring 20 and a blade 21 urged by spring 22 rises to latch the lever 18 (Fig. 3, not shown). When the desired temperature is reached a sensing device 17a causes member 17b to pull blade 21 down against spring 22 and unlatch lever 18. Spring 20 returns lever 18 to the position shown in Fig. 2 and a pawl 23 thereon steps the wheel 11, thereby causing the pawl 9 to re-engage teeth 11a and continue stepping the cams 12. A cam 26 on the same shaft as programme-selector cams 3 acts on a blade 25 coupled to member 17b to determine the temperature at which blade 21 unlatches lever 18. Instead of an electric motor a mechanical clockwork mechanism may be used.
