Title: Automatic case stacker
IPC: B65G57/30
Filed: 1962-11-02
Abstract: 958,449. Stacking. MATHEWS CONVEYER CO. Ltd. Nov. 2, 1962 [Nov. 9, 1961], No. 41494/62. Heading B8C.  Cartons supplied on a continuously moving endless conveyer 10 are delivered one at a time to stacking mechanism including a hoist 50 having a pair of arms 55, Fig. 4, on which the cartons are raised above the level of retractable members 73, 74 having flanges 81 which support each carton in turn during the formation of the stack. The leading carton is held by an abutment 15 on one of a pair of pedestals 40, until released automatically by an air cylinder and piston 24 for onward movement by the conveyer 10. A guard on the side of the piston head prevents the next carton from prematurely operating the piston. The leading carton operates a photo-electric cell thereby starting the hoist motor 65. At this time, the carton is held by stops 56 on the arms 55. A cam disc 68 is rotated to operate further circuits which cause the members 73, 74 to retract as the hoist rises and to be re-extended below the carton, before the hoist is lowered. At the same time the piston 24 is withdrawn to permit the next carton to reach the abutment 15. As this carton is raised below the first carton, the members 73, 74 are again withdrawn, returning below the second carton. When a stack is formed by further repetition of the cycle, the top carton operates a circuit to prevent the reextension of the members 73, 74 so that the stack is lowered on to the conveyer 10 for discharge. The arms 55 pass below the conveyer 10 so that the stops 56 are out of action. Further switches stop and subsequently re-set the hoist in its receiving position. Adjustable features include: side panels 13, for accommodating cartons of different width; bearings 72, to provide varying heights of lift hoist; and means for varying the mechanism timing, Fig. 7 (not shown).

Abstract: 1,168,059. Endless conveyer belts. ASHWORTH BROS. Inc. 4 Sept., 1968 [5 Sept., 1967], No. 42053/68. Heading B8A. A conveyer belt comprises a plurality of connecting links 2 forming at least one row of links extending centrally of the belt and longitudinally of its path of movement, each of said links 2 having opposed end portions, one of which defines a slot 18 extending transversely to, and elongated longitudinally of the path. Each of the links 2 has a pair of spaced leg members 14 extending longitudinally of the path, adjacent links being arranged in partially nested relation. Central rod means 28 are spaced along the belt, each having an axis parallel to the plane of the belt for pivotably and slidably coupling each partially nested pair of adjacent links 2, the central rod means 28 being connected to one link of said pair of links at the end portion opposite the slot 18. The rod means 28 are received through the slot 18 of the other link of the pair to couple the links together whereby the links are pivotable relative to each other about the axis of the central rod means 28 to allow the belt to bend in a direction normal to the plane of the belt. The rod means 28 are slidable longitudinally of the belt in said slots 18 to allow the belt also to bend laterally within the general plane of the belt; and outer rod means 36 are spaced along the belt and are connected to the links 2 to extend freely outwardly in both lateral directions from the central links to form the conveying surface of the belt outwardly of the links so that the outer ends of the outer rod means 36 are spaced apart during straight belt travel and may be collapsed into contiguous relationship during the lateral bending of the belt. As shown, the rod means 28 and 36 are formed by a single rod which is welded at 22 to each associated link 2. The central portion 28 of the rod is deflected out of line so that the top edges of the links 2 are in the same plane as the tops of the rods 36 to provide an overall plane load-bearing surface. Alternatively, the rods may be of stepped formation. The part 28 of each rod may be of stainless steel.

Abstract: 1282773 Degassing liquid coolant LINDE AG 26 Aug 1969 [27 Aug 1968] 42339/69 Heading B1M (Also in Division F4] A liquid coolant in a compression refrigeration system collected in collector 1 is purged of non-condensible gases by allowing the vapours from the liquid to pass through throttling orifice 4 into cooler 2 where coolant vapours are cooled by liquid coolant in coil 3 from collector 1 and condense and pass back via bypass tube 6 to collector 1, and non- condensible gases collect in the cooler 2, causing the pressure drop across orifice 4 to decrease. This causes the liquid level in tube 6 to drop, thus causing float switch 8 to open magnetically operated purge valve 10 to allow the non-condensible gases to discharge through purge line 9. This causes the pressure drop across orifice 4 to increase so that the liquid level in tube 6 also increases, causing float switch 8 to close valve 10. Instead of collector 1, the vapours may be taken from the liquefier of the system.
