Title: Improvements in and relating to electric timing mechanisms for washing machines and the like
IPC: D06F39/00
Filed: 1947-07-10
Abstract: 640,721. Time switches. BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1947, No. 18232. Convention date, July 10, 1946. [Class 38(v)] The duration of, e.g. the wash period in the washing cycle of a washing machine, is controlled by a mechanism comprising a switch-operating cam drum 4 connected to a gear wheel 9 driven through a pinion 38 and a slipping clutch 34 by an electric motor 31. Also meshing with the pinion 38 is a toothed motor 20 freely rotatable on the shaft 3 to which the drum 4 and gear 9 are fixed. Fig. 3 shows the minimum wash period positions, wherein the end 26 of sector 20 engages a pin 27 on the gear 9. The motor rotates the gears 9, 20, and therefore the drum, 4 clockwise, Fig. 3. until a toothless part 30 of gear 9 reaches the pinion, whereupon the gear 9 will be driven by the connection 26, 27. The duration of the wash period is adjusted by moving a dial 25 to the right, Fig. 2, to disengage gear 20 from pinion 38, and then rotating the dial to vary the distance between the end 26 and pin 27, the dial then being moved back. Now when the toothless part 30 reaches the pinion 38, gear 9 will stop, due to greater friction provided by a spring 12 and a ring 10 between gear 9 and a fixed hub 2 than that provided by a spring 23 and a ring 22 between gears 9, 20, until the end 26 re-engages part 27 to move gear 9 again. The pinion is mounted on a spring-urged pivoted lever 41 so that if, after adjustment, the teeth of gears 9, 20 do not exactly line up, the pinion will ride up over the teeth and bring them into line. Specification 620,210, [Group VIII], is referred to.

Filed: 1954-06-29
Abstract: 760,170. Centrifugal moulding machines. BUNFORD, M. A. June 29, 1954 [July 8, 1953], No. 19083/54. Class 87(2). [Also in Group XXIV] A mould is rotated by a shaft 4 which is driven through a hydraulically controlled clutch by an electric motor, see Fig. 2 (not shown), and which is braked hydraulically. An ejection table 12 is raised and lowered hydraulically. The valves of the hydraulic system are so interconnected that (a) the brake cannot be released until the table 12 is lowered ; (b) the clutch cannot be engaged until the brake is released ; (c) the brake cannot then be applied until the clutch is disengaged ; (d) the table 12 cannot be raised until the clutch has been disengaged and the brake applied, and (e) the brake cannot be released until a cover 13 is in position on the mould. In operation, a pump 7, Fig. 4, supplies oil through a pipe 21 and valves 28, 29 to cause a piston 35 to operate the brake, and either a piston 33 to operate the clutch or a piston 34 to operate a pump 5 for supplying oil through a valve 43 to a piston 46 see Fig. 5 (not shown) to raise and lower the table 12. The pump 7 also supplies oil for lubricating the machine at 19. The valves 28, 29, 43 are interconnected by providing notches 62, 63, 66, 65, Fig. 7, in which pins 64, 67 engage to lock the valves in desired positions. Hooks, one of which is shown at 68, see Fig. 9 (not shown) also lock the valve 29. These hooks are released by lowering the table 12, and replacing the cover 13, respectively. The height of the table 12 may be adjusted by rotating a handle 52, Fig. 1, which rotates a threaded shaft extending inside the piston rod in the cylinder 6, see Fig. 5 (not shown). The piston may have a rim on its lower surface which engages a recess containing oil in the bottom of the cylinder to cushion the lowering of the table. The valves are manually operated by handles 82, 83, 84.
