Abstract

1321256 Time switches H OBERGFELL 24 July 1970 [24 July 1969] 36129/70 Heading H1N A programme controller, for a washing machine or the like, in which a motor drives a programme cam through a planetary transmission comprising sun-wheel, internally toothed outer ring and planetary gear assembly one element being coupled to the motor, one to the cam and the third being normally free but can be held stationary to cause the motor to drive the cam, has an overrunning clutch incorporated in the transmission and the clutch and planetary transmission are constructed of plastics materials. A stepping drive using the above arrangement is described. A snail cam (1, Fig. 3, not shown) rotating continuously at one r.p.m. reciprocates a slider (2) to ratchet a pivoted plate (6) until a projection (21) thereon cams a locking plate (17) into engagement with the third element (19) of the planetary transmission to hold it stationary, causing drive to programme cams (9a and 9b). Cam(9b) then pivots a plate (10) to release a retention pawl (14) and slider (2) from the ratchet teeth on plate (6), whereupon springs (5, 8 and 18) restore respective plates (2, 6 and 17) to their rest positions. The profile of cam (9a) locates the rest position of projection (21) and thus of plate (6); this determines the number of ratchet teeth to be moved before the next locking of the transmission occurs and hence the time interval between programme steps.
