Abstract: 983,553. Valves. CHEREMA A.G. June 13, 1961 [June 13, 1960], No. 21325/61. Heading F2V. [Also in Divisions D1 and H2] A device for controlling a sequence of operations, e.g. in a chemical cleaning machine (see Division D1,) comprises a cam drum arranged to actuate switches and/or valves mounted on a side plate which is movable to shift the switch and/or valve operators out of range of the cams during rotation of the drum. As shown, there are two side plates 44, 45 pivoted at 42, 43, linked together at 46 and urged apart by a spring 47. Plate 44 carries two change-over valves 60, 61 and plate 45 carries a change-over valve 62 and a switch 71 which are controlled by respective plungers 69, 73 which co-operate with cams 80 on the drum 31. The latter may be rotated by a hand wheel 32 (Fig. 4), by a pressure-operated pawl 102 (Fig. 6), acting on a ratchet wheel 101 on the drum spindle, or by a synchronous motor supplied with impulses. The drum is located in each of its positions by a spring-loaded roller engaging a star wheel on the drum spindle, the star wheel also operating a switch (Fig. 5, not shown), controlling an electromagnet which operates a valve to supply fluid to a cylinder 48, the arrangement being such that the electromagnet can only be energized when the drum is in an operative position. The cylinder 48 is connected to plate 45 and contains a piston 50 connected to plate 44, so that after the drum is in an operative position pressure applied to the cylinder moves plates 44, 45 inwards to engage the plungers 69, 73 with the cams 80 so as to operate the appropriate switches and/or valves. Plate 45 may carry a plunger arranged to enter radial holes in the drum so as to prevent rotation of the drum when the plates are in their inner positions (Fig. 8, not shown). The plate 44 also opens a switch 111 when in the inner position. A rod 115, manually slidable within the drum, against the bias of a spring 116, carries a plate 117 having two recesses 119, one of which is sloped so as to retract a catch 122 during movement to the right of rod 115, the catch subsequently being ejected behind the disc 117 by a spring 123 to lock the rod depressed, in which position a change-over switch 91 is operated. When rotation of the drum and the disc 117 brings the other recess opposite catch 112, the rod 115 is returned to the left.
