Filed: 1929-06-24
Abstract: 317,844. Wistoft, S. Aug. 25, 1928, [Convention date]. Storage; filling storage receptacles.-In coinfreed vending machines fitted with double delivery tubes for holding the goods, the double storage tube comprises an outer tube 3, Figs. 1, 2 and 3, having an open front and an inner tube 16 hinged at 5 to the top of the outer tube. Goods are stored in the inner tube and in the space between the inner and the front of the outer tube. The goods in tube 3 are delivered first and, when this tube is empty, the inner tube is released and moved by a spring 19 about its pivot 5 into alignment with a hopper 12 leading to the delivery mechanism. The tube 16 is locked in its non- delivery position by pivoted arms 20 controlled by springs 22, the arms having notches 26 which engage pins 18 extending from the sides of the tube 16 and guided in the top portions 7 of T- shaped slots 6, 7 in the sides of the tube 3. The goods are retained in the inner tube by a plate 9, to a downward extension of which the hopper 12 is hinged at 10, the hopper being held in position by a spring 14. When the last packet of goods leaves the tube 3, the locking arms 20 are released by being engaged by arms 28 on a heavy plate 27 slidablv mounted on the front wall of the tube 3 and having a pivoted arm 44 with a foot 45 resting on top of the pile of goods in the tube 3. Grooves, in which the edges o.f the front wall engage, are formed with the body 27 by a distance piece 33 on one side and by a single-armed lever 36 on the other side, the lever having a projection 38 spaced apart from the plate 27 and being held in position by a spring 41. When the inner tube 16 is to be refilled, the releasing plate 27 is detached by moving the lever 36 against the spring 41 by means of a handle 40. The releasing plate is replaced to rest on top of the pile in the outer tube, when this is refilled. If the delivery mechanism of the machine is returned without a packet having been removed, the packets will strike against the hopper 12 or against the next packet contained therein. The hopper 12 is thereby moved about its hinge 10 against the spring 14 and prevents the machine from being put out of order.

Abstract: 724,238. Foundry plant COMBUSTION ENGINEERING-SUPERHEATER, Inc. Aug. 1, 1952 [Aug. 25, 1951], No. 19497/52. Addition to 704,815. Class 83 (1). Foundry plant according to the parent Specification is provided with automatic apparatus for moving each mould withdrawn from the mould-assembling machine into a device, above the line of trucks, which lower the received mould onto a truck which carries it towards the pouring station. This apparatus is preferably entirely automatic. The track 260 is extended and curved as shown at 260<SP>1</SP>, Fig. 7, and the drags 12 have bumpers 380 so that the mould being withdrawn from between the arms 61, 62 not shown) will push previously withdrawn moulds along said track 2601 until the foremost one enters the lowering device 385, the bars 28 of the drag passing over rollers 421 carried by arms 422, Figs. 10, 13, pivoted at 423 on a slide 412. The rollers 421 are on an incline down to the right of Fig. 10 so that the mould tends to press against a stop 425 on one arm 422. The slide is then moved down by a fluid-pressure cylinder 406 until the rollers 421 pass between rollers 426 on fixed axes so arranged that the mould is supported just over the level of bars 369 carried by each truck 33 and inclined to the left, Fig. 10. The arms 422 are then moved apart to release the mould by a fluid-pressure cylinder 429 and stops 368 of an advancing truck engage inside the lower edge of the cope and pull the mould to the left until it rests evenly on the bars 369. The slide 412 is then returned to its uppermost position and the arms brought together again ready for a repetition of the process. The starting switch of the motor driving the chain of trucks 33 may be closed by a press-button relay and opened by any of a number of press buttons or by a time switch a few seconds after light from L5, Fig. 23, strikes a photo-electric cell C<SP>5</SP>, owing to the absence of a mould at truck level, which cell C<SP>5</SP> operates the switch through an amplifier A5, relay R5 and switch 449. When a mould is moved down to obstruct the light from L5 the motor starts again, should it have been unobstructed long enough to cause the motor to stop. The fluid-pressure cylinders 406, 429 like those of the rest of the plant are controlled by solenoidoperated valves, but the circuits for the solenoids include switches operated by photoelectric cells C<SP>1</SP>, C<SP>2</SP>, C<SP>3</SP>, C', Fig. 11, masked by the moulds as they are moved as well as switches 437, Fig. 13, and 442, 439, 440, Fig. 10, operated by moving parts of the device 385 so that the whole process is automatic. The relay R5 also opens a switch 448, when the light from L5 is unobstructed, to prevent a fresh mould from being lowered if the previous one has not been carried away by its truck.
