IPC: A01F12/44
Filed: 1920-07-09
Abstract: 148,153. Casali & Figli, F. Aug. 1, 1913, [Convention date]. No Patent granted (Sealing fee not paid). Thrashing-machines.-A machine for thrashing and hulling grain, clover, and other seeds comprises two beaters, two dressing-boxes, and two elevators, movable inclined plates or boards being provided for changing over from grain thrashing to clover hulling. When grain is dealt with, the first beater A thrashes it and the second beater B removes any husks which may still adhere to it after it has passed through the first dressing-box. The sheaves are fed between the beater A and its concave A', and the straw passes out over the shakers C, grating S, and apron u, u<1>. The grain passes down inclines d, d<1> to the main screen F which separates short straws &c. and discharges them at t. From the screen F the grain runs down inclines into the first dressing-box G, through the screens g, g<1>, g<2>, g<3>, and over the inclines e, e<1>, e<2>, from which it passes to the elevator H, husks &c. being blown out by a fan L. The elevator raises the grain to the second beater B which rubs it against wire gauze on the counter-beater B<1>. The grain then passes over a pivoted incline on to the screen m, m<1> of the second dressing-box M, where it is subjected to an air blast from a second fan P. From the box M the clean grain passes into the sorting- screen N, and thence to the delivery spouts R. When clover is dealt with, the heads containing the seeds are removed from the stalks by the first beater A and pass through the screen F to an inserted incline and then down a shoot direct to the elevator H. The seeds are rubbed out by the beater B and pass down inclines b<2> to the dressing-box G and thence into a second elevator which delivers them to a screw conveyer leading to the second dressing-box M. From this box they pass to the spouts R through an outlet at the side of the screen N. The material from part of the beater B may be passed direct to the incline e along an inclined board.

Title: Method of and apparatus for manufacturing can bodies
IPC: B21D51/26
Filed: 1939-07-10
Abstract: 521,789. Severing by grinding. WITHERS, J. S. (Gonser, B. W.). July 10, 1939, No. 20072. [Class 60] [Also in Group XXII] Circular or rectangular can bodies are made by continuously feeding through a tube forming apparatus a thin strip of steel of a width approximating the circumference of the body and of a length sufficient to form a number of can bodies, continuously welding the edges of the strip and dividing the tube into lengths during the feeding operation. The dividing operation may be effected by an apparatus mounted in a carriage 68 which is traversed backwards and forwards on tracks 70 during traverse of the tube by a rotating cam 123 driven by chain gear 122 from a shaft 119 which is driven from the same shaft that drives the strip feed-rolls. The carriage is clamped to the tube at the desired moment by rubber-lined shoes 74 normally held out of action by springs 79. Severing is effected by a number of Carborundum or like positively-driven discs 103 carried by radially movable members 102 in a sleeve 94, which is continuously rotated by a motor 100 through gearing 98, 99. The discs are normally held out of action by springs 105. The shoes are operated first when a pivoted contact on the carriage engages an adjustable contact strip on the bed. A solenoid 92 is thus operated to move inwards a slotted plate 90 which moves a pair of levers 85, 86 on their pivot 89 to engage flanges 81, 82 on a split band 80 which is thus contracted against the action of a spring 84 to push the shoes against the tube. Shortly after this occurs, a second pivoted contact 128 on the carriage engages a second contact strip 132 to operate a solenoid 115 which moves a cam ring 110 against the action of a spring 116. This ring has inclined slots engaging pins 109 in a four part split band or track 108 with overlapping ends. The parts of the band are moved radially by the ring, being provided with radial grooves 108b engaging pins 108c on a fixed member 108d. The cutters are thus pressed into contact with, the tube. Insulating blocks on the pivoted contacts prevent operation of the solenoids during return of the carriage.
