Feeding blanks.-A machine for forming rings 11, Fig. 8, such as are used in the making of nunmetallic gear wheels described in Specification 225,213, [Class 80 (i), Gearing, Belt &c.], from overlapping segments 10, of material such as canvas treated with a phenolic condensation product, comprises an annular holder 42, with a step-by-step rotary movement and a shoot 15 from which the segments 10 are fed. The holder 42 is mounted in driving engagement with a ratchet disc 37 which rotates on a pin 32 carried by a disc 30 adjustable on the support 12 to allow holders of different sizes to be used. A friction disc 39 is mounted in the ratchet disc and engages a collar 34 on the pin with a pressure which is adjusted by the spring 35 and nut 36. The movement of the disc 37 is derived from a spring pawl 77 on an arm 74 adjustably connected to a slide 68 which is reciprocated by a connecting rod 69 and an adjustable crank disc 71 on the shaft 27. A reciprocating plate 18 works through the space between the lower end of the shoot 15 and a table 14 and has at its forward end fingers 19 which are provided at the rear ends with shoulders slightly less in depth than the thickness of the segments and arranged to conform with the rear edge of the segments. In the retracted position of the plate 18, the lowest segment lies on the fingers, and is carried forward by the shoulders in the forward movement of the plate to a position over the holder. A pair of gravity hooks 48 engage the rear edge of the segment in this position and strip it from the fingers during their retracting movement allowing it to fall into the holder, where it is pressed firmly in position by a presser 62 resiliently carried by a vertically reciprocating bar 50. All the parts are actuated from the shaft 27 which is driven from a main shaft 92 by a friction clutch 80, 84 normally closed by a. spring 82 and automatically opened by a pin on the holder actuating suitable bell-crank mechanism on the completion of one turn.

Abstract: 536,725. Feeding sheets. ARNOLD, C. (Aetna-Standard Engineering Co.). Sept. 19, 1939, No. 26194. [Class 100 (i)] A sheet-feeding apparatus which is especially applicable to feeding metal sheets S from a pickling tank T, Fig. 2, comprises a number of suction cups 35 mounted on curved arms 27 by a support which can yield against the action of springs 37, and which are given combined reciprocating vertical and horizontal movements obtained from a piston 43, Fig. 4, reciprocated by means of compressed air, steam, &c. supplied from a tank P under control of a sliding valve 49 connected by a rod 80 to a lever 72 which is freely mounted on an oscillating shaft 71 and is capable of being held by a spring- pressed lever in positions corresponding to the supply of fluid to the two ends of the compressed air &c. cylinder 42. The piston is connected by a rod 38 and links 39, 40 to the frame supporting the suction cups 35 and guide channels 17, 18, 19, 20 guide the frame so as to direct the separated sheets to forwarding rollers 129, 130. The speed of travel of the cups can be hand-controlled by an adjustable dashpot device comprising a pair of reciprocating pistons 94, 95 moving in cylinders 92, 93 immersed in a bath of oil 90 and having outlets 104, 105 and 112 controlled by adjustable valves, and inlets 106, 111, controlled by check valves. The air pressure in the cups 35 is controlled by a valve sliding in a casing 134 which is operated by a rod 148 connected to a lever 153, Fig. 2, capable of being held by a spring-pressed roller or a lever in positions corresponding to connections to atmosphere or to a suction pump. This lever can also be held in a mid-position which traps air in the cups as they pass into contact with an immersed plate, and so prevents liquid from being drawn through the cups. Should, however, any liquid be drawn in, it acts on a valve 178, Fig. 16, which rises to cut off connection with the suction manifold. In a modified form the suction cups are arranged to move transversely to the motion of the final conveyer which advances the separated sheets.

Inventor: BOWKER RICHARD SKELTON
Filed: 1956-09-04
Abstract: 860,588. Record card sorting machines. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Aug. 8,1957 [Sept. 4, 1956], No. 26996/56. Class 106 (1). In a record card sorting-machine of the kind in which the cards are guided to their respective pockets by a series of blades 14, the blades are separated into two or more groups each group being controlled by an operating member, no two adjacent blades being controlled by the same operating member. As shown in Fig. 3, the blade tips are arranged in a straight line and alternate blades are supported on plates 15 and 16 which inter-mesh, the plates being moved selectively to cause the card 3 to pass over the desired blade. The use of two operating plates for alternate blades doubles the time available for the operation of the sorting magnet. For a high-speed machine sorting magnets release the appropriate plate 15 or 16 for downward movement under spring action, the plates being reset by cams. In a slower machine the plates may be displaced by the magnets directly. The invention may be extended to sorting alphabetical and numerical data, about 36 blades then being used. To provide a sufficient spacing between the tips of the blades the card-feeding cycle is lengthened so that the sensing period forms only a fraction of it. Specification 242,654 is referred to.
