Title: Apparatus for receiving boxes from the termination of a conveyor at an upper level and conveying them to the pallets of a stream of pallets at a lower level
Filed: 1967-05-30
Abstract: 1,213,797. Foundry plant. RUBERY OWEN & CO. Ltd. 28 Nov., 1967 [30 May, 1967; 10 Oct., 1967], Nos. 24817/67 and 46161/67. Heading B3F. [Also in Division B8] Boxes, e.g. filled foundry mould boxes from a moulding machine, are received on a platform 12, 15, Fig. 9, at the end of a conveyer 11, for transfer to a stream of pallets, e.g. of a rotarywheel or in-line casting-machine, at a lower level, by apparatus, Fig. 2, having, for engaging opposite sides of the box and supporting it when the platform 12, 15 is lowered, swingable latches 59, 60 and fixed support pads 67 on members dependent from a carrier 46 which is raisable'and lowerable in a frame 31 supported from a carriage framework 32 so as to be reciprocable horizontally whereby the carrier 46 when retracted with the frame 31, as shown in Fig. 2, from the platform 12, 15 to a position above the pallets, can be lowered thereto from the frame before the latches are swung away to leave the box on the pallet. The apparatus is automatically actuated by fluid-operated cylinders 14, 17, 35, 44 &c. or electric power, controlled by trip mechanisms or limit switches. A box moves under gravity along the conveyer 11 and is halted on the roller platform 12, 15 between lateral guides 23 by a stop 22 which causes a trip to raise a stop 13 for detaining any succeeding box and to lower the platform so that the first box is left suspended on the carrier 46. The frame 31 is traversed by the cylinder 35, with guides 34 from the frame coacting with rollers 33 on the framework 32. When the frame with carrier 46 is above the pallets, the carrier is automatically turned to orient the box with respect to the receiving pallet and is lowered from the frame 31 together with its guide-column extension 43 running in rollers 41 on the frame. Legs (52) 53 depending from one side of a plate base 51 of the frame 31 have adjustable feet 68 which stop the lowering of the frame by their engagement with abutments 69, Fig. 1, on a two-armed member 72 pivoted below the platform 12, 15. The member 72 is operated by a cam track 76 on the rotary-wheel casting-machine to lower the carrier 46 so that the carried box is at the pallet surface before the latches 59, 60 are swung open. Trips cause return of the parts to the positions shown and then lowering of the stop 13 to start a fresh cycle. Should a loaded pallet approach the box-receiving position, an alarm is given and/or the moulding machine stopped and if the carrier 46 fails to lift after unloading, the pallet stream is stopped. There may be two receiving platforms 12, 15 and two loading frames 31, one for each of two conveyer streams for supplying moulding boxes.

Abstract: 1,220,708. Partly magnetic switches. GENERAL ELECTRIC CO. 30 Sept., 1968 [30 Oct., 1967], No. 46201/68. Heading H1N. A magnetically retained switch has three component assemblies with interfitting parts. The upper assembly 10 comprises a transparent push button 36 enclosing a lamp (not shown) and slidable in an insulating housing 14 having legs 146 fitting over bars 148, 150 in the housing ports 96, 98 of the centre assembly 44. The latter retains between its housing ports a coil 70 surrounded by a tubular magnetic member 74 between magnetic discs 76, 78 which also guide a plunger 90 having an armature port 92 and a non-magnetic rod 94 which extends through the disc 78 and a boss 80 thereon to engage a contact operating member 64 in the lower assembly 50. Housing ports 52 of the lower assembly have securing rivets 162, 164 which legs 136, 138 of the centre housing 44 fit over. The contact operating member 64 controls contacts (not shown) in the assembly 50 and also has an extension 69 supporting a spring biased contact bridge 128 which co-operates with contacts 116, 118 in series with the coil 70. When the pushbutton 36 is pressed and moved against the bias of a spring (42, Fig. 3, not shown) in the housing 14 it acts on a rod (40) to move the plunger 90 downward to drive the member 64 against the bias of a spring (62) and close the contacts 116, 128, 118 to energize the coil 70. The plunger armature 92 is held attracted to maintain the contacts operated until its coil circuit is broken elsewhere. The upper housing 14 is provided with spring retainers 30 for panel mounting of the switch.

A device for sampling liquids, such as oil, comprises an outer tube 3 and an inner tube 6 adapted to co-operate with a sealing ring 20 located on an end portion 19 of the outer tube. The inner tube is loosely guided in rings 7 secured to the outer tube and connected to an extension tube 4 via a screwed connection 12, 18; the outer tube is also connected to an extension tube 1 by a similar screwed connection. In operation, the inner tube is lifted by means of a handle 11 so as to move the lower end of the inner tube out of contact with the sealing ring 20. Both tubes are then inserted into a tank of liquid so that the latter rises into both tubes. The inner tube is then pushed downwardly to seal the outer tube so that when the device is withdrawn from the tank a measure of liquid is trapped between the inner and outer tubes. In order to increase the length of the device futher extension tubes may be connected together. In a modification, a single inner tube (6<SP>1</SP>, Fig. 7) is normally pressed into sealing engagement with a sealing ring in an outer tube (3<SP>1</SP>) by a spring (22), the inner tube being actuated by a Bowden cable. The outer tube may be connected to a flexible tube (24).
