IPC: A43D83/00
Filed: 1947-09-29
Abstract: 632,273. Ornamenting shoe uppers. MEAKER, J. W. Sept. 29, 1947, No. 26275. Convention date, April 9. [Class 17 (ii)] [Also in Groups VIII and XL (a)] Uppers of shoes of various sizes and shapes may be electro-perforated by passing an electrical discharge through the upper between an inner expansible electrode, which contacts inner portions of the shoe and which will serve for a range of sizes, and a manually-operated electrode which is passed over selected portions of the upper. The shoes are clamped by a spring 15 between heel and toe stops 12, 13 carried by a platform 10 of insulating material pivotally supported on a tube 16 attached to the base 18 of the machine. Alternatively, a number of shoes may be held by heel and toe clips on the sides of a box mounted on the tube 16. The inner electrode comprises an expansible sock-like member 20 knit of close-meshed metallic yam or thread which is pressed into contact with the shoe interior by inflating a bladder 21 shaped to fit the shoe interior when inflated, or, in an alternative form, it may be fitted over an inner foot-shaped piece of sponge rubber. The toe, heel and top portions of the member 20 may be of ordinary yarn, if desired. The electrode 20 is connected by a detachable spring clip 26 through fixed resistances 24 to one side of the secondary of a step-up transformer 25, the other side being connected to external electrode 27 supported at the end of a handle 28 by which it may be passed by the operator over the shoe upper, a roller 29 preventing scratching. The primary of the transformer is connected to supply mains. A pair of switches 31, 32, the former being on the handle 19 by which the platform 10 may be manipulated, and the latter on the handle 28, and which are of the type which require to be closed against spring pressure, are provided for the safety of the operator.

Title: Improvement in derrick cranes
IPC: G05G7/04
Filed: 1937-09-29
Abstract: 502,189. Controlling the luffing-gear of cranes; locking levers; clutches. DAW, E., and DEWES, R. H. Sept. 29, 1937, No. 26320. [Class 78 (v)] [Also in Group XXIV] The clutch lever, which connects and disconnects the luffing-mechanism of a jib crane to the power gear, is fitted with spring-actuated mechanism which passes its dead centre as the lever progresses from the " off to the " on " position and vice versa, thus acting positively to retain the lever in both of these positions. Figs. 1 and 3 show the lever 2 pivoted at 3 and actuating the claw clutch member 4 to drive the luffing- drum 5. In moving the lever to the " on " position, the cranked portion moves from right to left in the slot 6 in the fixed plate 1 ; the rod 7 sliding through the bearing 8 and compressing the spring until the dead centre is passed and then rising again as the spring re-expands. When the luffing motor is reversed, the drum 5 is held by the self-sustaining pawl 17 and the teeth force the members 4, 5 apart sufficiently for the spring to pass the dead centre. The spring then completes the movement and forces the lever into the recess 15 where it is secure until again positively operated. Various methods of mounting the rod 7 are described. As shown, it is connected to the lever by a ball-joint 10 with or without play, and has rolling contact at 14 with the plate 1, with or without a restraining trackway on the surface of the plate. The bracket 8 is mounted on ball bearings 12 and its shank 11 may have some play in the bearing so that it can tilt relatively thereto. In addition, the bracket may slide bodily in a direction perpendicular to the plate by compressing the spring 13.

Abstract: 388,693. Hinges. HADDAN, R., 31, Bedford Street, Strand, London.-(Moffats, Ltd., Dennison Avenue, Weston, Ontario, Canada.) Sept. 22, 1932, No. 26397. [Classes 65 (i) and 65 (ii).] An oven-door hinge, which is hidden by the door 2 when closed, comprises an arcuate hinge 3 which can slide around a curved fulcrum 6, and radial slots 3e which support the door 2 through pins 12 so that the door may be pivotable about the hinge 3 to avoid the bottom 13 of the door digging into the front of the porcelain-enamelled stove face 5. The hinge tends to remain in the closed position due to the action of a spring 7 pulling on a roller chain 9. Shoulders 11 engage the inner side of the oven when the door is fully open. To remove the door a pin is passed through the hole 3f to bear on the oven front and prevent the spring 7 from withdrawing the hinge 3, and the door pins 12 lifted out of the slots 3e. The hinge is formed of a cast body and side plates of sheet material which are keyed at 3c and riveted at 3d to the opposite sides of the body.
Patent GB-759580-A (GB)
Title: Apparatus for, and method of, straightening filled cans
IPC: B21D1/08
Filed: 1954-09-14
Abstract: 759,580. Restoring shape of filled cans. CAN-DO, Inc. Sept. 14, 1954 [Sept. 18, 1953], No. 26564/54. Class 83 (4). A method of removing the surface irregularities from filled cans comprises applying pressure to the opposite ends of the can by rigid surfaces, feeding the can between a pair of cooperating dies shaped to enclose the periphery of the can and thereafter engaging the can with the dies to remove all irregularities therefrom. Apparatus for carrying out the method comprises a frame 14 carrying a table 24 and a plate 30 on which is mounted feeding means 16 and can periphery engaging means 18. The feeding means comprises a yoke member 36 pivoted to the plate 30. A stop member 52 limits the pivotal movement of the yoke away from the periphery engaging means 20. End plates 54 and 56 are detachably mounted in the arms of the yoke member and the plate 56 is spring- loaded and slidable in its mounting to enable the can ends to be clamped between the plates. A lever 82 having a cam 84 engaging the end of the plate shaft 68 operates the plate 56. The contents of a can gripped between the end plates will be pressurized and such internal pressure entirely or partially removes the surface irregularities. In the latter instance the can is fed to the periphery engaging means 18 by manipulating the lever 82. The periphery engaging means 18 comprises pivotally interconnected die blocks 86 and 88 the block 88 being split into parts 90 and 92. The part 92 is pivoted on the plate 30 and spring-loaded in the elevated position to faciliate feeding of the can into the die 134. The block 86 which is pivotally mounted on the plate 30, has a projection 108 which is connected by linkwork to a spring-loaded foot pedal 124. The dies 132 and 134 are detachably mounted in the block 86 and part 90 respectively. Depression of the pedal 124 clamps the dies around the periphery of the can and removes any irregularities. A stop plate 113 on the link 111 limits the opening movement of the die block 86. The dies are readily interchangeable according to can size.

Title: Hydraulic safety cut-off valve devices for hydraulic systems suitable, e.g. for actuating aircraft control surfaces
Inventor: PARKER WARDE LEMOYNE
IPC: B64C9/00
Filed: 1953-09-29
Abstract: 732,953. Fluid-pressure servomotor-control systems; safety cut-off valves. NORTHROP AIRCRAFT, Inc. Sept. 29, 1953, No. 26735/53. Class 135. A safety cut-off valve for use in a hydraulic servomotor system actuating, e.g. aircraft control surfaces, comprises a casing 32 housing valve members 27, 41 urged towards. closure by springs 35, 42 and connected by rods 36, 47 to one end of a lever 63 whose other end coacts with a rod 59 of a cut-off valve member 52 urged off its seat by a spring 57. The valve members 27, 52 are disposed in the pressure: line 19 and the valve member 41 in the return line 21 between a source of liquid pressure and the control valve 22 of a double-acting servomotor 24 whose cylinder 26 is operatively connected to the control surface 14. The piston valve member 70 of the control valve 22 in its neutral position leaves the cylinder ports 74 partially uncovered and is formed with bores through its lands to provide neutral leakage paths to and from either side of the piston 25 to preload the piston and prevent its movement against normal air loads. Several such control valve and servomotor units may be fitted in the system, each having its own safety cut-off valve device. Under normal operating conditions, the valve members 27, 41 are unseated by the flow of liquid through the lines 19, 21, the lever 63 being positioned to permit the opening of the valve 52 by the system pressure and its spring 57. In the event of the fracture of either or both lines 19, 21, the loss of pressure in the line 21 results in the valve 41 closing to move the lever 63 to close the valve 52 to cut off the supply of pressure liquid to that particular unit without affecting the supply to the other units in the system. Leakage to a chamber 64 due to the loose fit of the valve 52 in its bore 54 holds the valve 52 closed even after repairs are effected until it is reset in its open position by the opening of a bleed valve to exhaust liquid from the chamber 64. Specification 701,513 is referred to.

Abstract: 897,199. Sampling sugar-beet &c. COCKSEDGE & CO. Ltd. July 20, 1960 [Aug. 5, 1959], No. 26739/59. Class 58. Apparatus for sampling sugar-beet &c. comprises a vertical sampling tube 55, Fig. 1a, secured to the vertical shaft 34 of an electric motor 36 mounted in a carriage 28, which can be moved up and down, in a carriage 25, by an electric motor 183 acting through a winch having two drums, one of which is shown at 85, and lifting and lowering cables 86 and 87. The carriage 25 can be moved horizontally, to and fro, by an electric motor 80 acting through chain and pinion mechanism. Parts of the lower end of the tube. Fig. 3, are cut away along vertical edges 63, 64 and helical edges 65, 66 to form two notches. Two helical scoop plates 68 and 69 are mounted, respectively on pairs of rods 58, 59 and 60, 61, which are axially movable within the tube. The radius of the tube may be 6 to 10 inches and the width of the scoop plates may be between one-quarter and one-third of this radius. The scoop plates have vertical extensions 70, 71 with concave leading edges 74, 75 and straight trailing edges 72, 73. At the commencement of sampling, the scoop plates are positioned so that the helical and straight edges of the scoop plates and notches coincide. A sample is taken by lowering the rotating tube to a desired depth into a load 13 of sugar-beet &c., Fig. 1a, so that a sample is scooped into the tube. The tube is then withdrawn upwardly from the load and moved sideways over a hopper 100, Fig. 1b The scoop plates are lowered, e.g. pneumatically away from the end of the tube and the sample falls through the hopper on to a shaking conveyer 101, from which it falls into a container 106. A pan 104 on a rotating arm 103 is passed through the falling sample to collect a fraction thereof, e.g. one-sixth, constituting a secondary sample. The scoop plates are then raised and the tube is returned to a sampling position over a load of sugar-beet &c. The depth of penetration of the tube into the load can be determined by setting control mechanism, Fig. 6 (not shown), associated with a box 90 and the apparatus can be operated by pressing appropriate button switches.

Title: Improved process and apparatus for producing the germination of seeds
IPC: A01C1/02
Filed: 1935-09-27
Abstract: 468,056. Assisting germination. BOUILLON, C. G. V. Sept. 27, 1935, No. 26788. Void. Convention date, Sept. 28, 1934. [Class 58] Seeds for germination are placed in a hopper 36 and by opening a blast of air from a fan 21 to a chamber at the bottom of the hopper are carried up a conduit 35 to the top of a vertical container down which they fall on to a loose perforated plate 28 supported on catches 29. The container has two opposite walls 1, 2 perforated at the side 1 communicating with a trunk 7 divided by horizontal perforated plates and connected by a conduit 20 to the fan 21 and the side 2 communicating with an outlet trunk 8. Water passes from a tank 13 to a nozzle 10 in the trunk 7. A regulator 16 adapted to close an air passage 15 to the tank and controlled by the pressure of air in the trunk 7 governs to some extent the supply of water. When sufficient seed has entered the container for one day's supply, the water and air supplies are turned on and germination started. A thermostat 61 may be used to control the air supply automatically. The next day the lid of the container is opened, a perforated plate 28 laid on the seed in the container and another day's supply of seed introduced on top of this plate, the germination of the second supply then being started. This procedure is repeated until the germination of the lowest layer is complete ; the catches 29 are withdrawn and the bottom layer allowed to fall into a discharge aperture 30<a>, the catches 29 returning to engage the succeeding plate 28. The plates 28 may be separated by stays to prevent pressure on the seeds. In a modification, the previously soaked seeds are arranged in independent vats placed successively one above the other in a vertical container and the air is arranged to pass upwards through the perforated bars of the vats. The bottom vat is removed, when the seed therein is fully germinated, by screw jacks and a fresh one inserted at the top.
