Title: Vibratory screening apparatus for finely divided material
IPC: B07B1/46
Filed: 1977-04-25
Abstract: 1526663 Vibratory screens DERRICK MFG CORP 25 April 1977 17121/77 Heading B2H In a vibratory screening apparatus, a pair of screen cloths 14, 15 in face to face abutment are supported on a frame 10 and the openings in the screen cloths are at least twice as wide as the wire diameters of the screen cloths. The openings of the lower screen cloth 15 are at least as large as, but not in excess of 50% larger than, the openings of the upper screen cloth, with the majority of the openings in the upper screen cloth intersected by the wires of the lower abutting screen cloth. The frame 10 includes supporting members 11, 12 presenting upwardly arched surfaces which support the screen cloths in upwardly arched formation so that the wires of the lower screen cloth are locked into those of the upper screen cloth in such a manner that the plane defining the upper surfaces of the lower screen cloth is above that defining the lower surfaces of the upper screen cloth. With such a construction, the wires of the lower screen cloth effectively prevents a particle A of material being screened from becoming lodged in an opening of the upper screen cloth. Also, because of the arched condition of the screen cloths, there is a very slight relative movement of the screen cloths during vibration. A backing screen 24 underlies the two screen cloths and a cushioning strip 26 is interposed between the backing screen and the frame 10. The screen cloths are tensioned by a rail member 20 connected to a flange 17 by a bolt and nut assembly 22.

Title: Improvements in or relating to machines for operating on shoes
IPC: A43D79/00
Filed: 1959-05-25
Abstract: 925,963. Shoe-making machines. BRITISH UNITED SHOE MACHINERY CO. Ltd. May 25, 1959 [May 26, 1958], No. 17668/59. Class 17 (1). When a last 50 bearing a shoe 36 is placed on a jack 700, a switch M-11 is closed, as a result of which a heel form 40 and a loader block 68 are moved to their operative positions and the jack moves from a forward shoe receiving station towards a rearward heel-attaching station 52; and, as the jack so moves, the lower ends of bellcrank levers 822 are swung inwardly to engage faces 272, 274 of a plate 270 secured to the last; to orientate the last on the spindle 266 of the jack. At the same time, a latch 830 is swung, so that its V-shaped lower end engages in a V-shaped slot 834 in the rear end of the plate 270, to retain the last on the jack. The switch M-11 is closed by reason of the upward movement of a plunger 856, the lower end of which extends as a sensing member below the abutment face 816 of the jack and which is raised as the last is slid on to the pin 266. Follower portions 822a of the bell-cranks 822 run in a circular groove 824 in a boss on a rod 826 vertically slidable in a bore 828 of the jack and linked, through a yielding connection with a lever 840 rocked, against the action of a spring 849, by a cam 852 as the jack starts its rearward journey from the shoe receiving station. A follower portion 830a of the latch 830 also engages in the groove 824. During rearward movement of the jack, the rear end of the shoe engages an abutment plate 452 of a back gauge, moving it rearwardly to displace a plunger 474 of a normally open micro-switch M-6 across the terminals of this switch just as a slide-plate 456, upon which the plate 452 is adjustably mounted, strikes a fixed stop-screw 468. This causes energization of a solenoid which operates an hydraulic valve to cause the heel seat 34 of the shoe to be forced with preliminary pressure against a heel 28 in the form 40 positioned over a nail die 66. Hydraulic pressure also causes the driving of nails, then in passages 64 of the die 66, into the heel and heel seat and to clinch them against the heel plate of the last. As driving pressure builds up, as the nail drivers meet resistance, the heel seat of the shoe is forced against the heel with additional pressure. After the nails have been driven predetermined distances, the drivers are lowered; and the jack, last and heeled shoe are raised vertically and then advanced horizontally to the shoe receiving station. As the jack reaches this station, the last is released and an ejector 702 is actuated by fluid pressure means 704 to eject the work, which falls into a cloth cradle. Specification 863,464 is referred to.
