Title: Safety control system for hydraulically operated machines
Inventor: VALYI EMERY IMRE
IPC: B30B15/16
Filed: 1968-06-28
Abstract: 1,222,846. Valves. E. I. VALYI. 28 June, 1968 [22 Aug., 1967], No. 31007/68. Heading F2V. [Also in Divisions H1 and H2] A series of electric switches of valves are controlled in sequence by a cam-shaft which can be moved laterally to allow individual manual control of each switch or valve. As shown, piston valves 14 controlling respective rams 47 of a press are actuable by a cam-shaft 40, 45 carried by block 30. The latter is movable bodily by ram 32 to disengage the cam-shaft and permit spring-return of the valves or manual control thereof through bolts 50. Each ram 47 is associated with a pair of switches 56, 57 in parallel such that, when the first valve is opened, its respective ram starts to move and opens 56 to stop the cam-shaft motor 41. The motor restarts when the ram closes 57. The first ram must therefore complete its travel before the second can be actuated. One cam may stop the motor after one revolution thereof. In a modification, the cam-shaft is fixed and actuates the valves through tappets in a slidable block.

Title: Improvements in or relating to apparatus for feeding sheets
IPC: B65H3/08
Filed: 1927-11-23
Abstract: 306,582. Rose, A. G., and Rose Bros. (Gainsborough), Ltd. Nov. 23, 1927. Sheet - separators; pile supports. - A sheet - feeding apparatus of the kind in which the top sheet of a pile is buckled while engaged by a suction device, which is oscillated to detach the sheet, is constructed with a horizontally reciprocating pile support 31 which is advanced to buckle the sheet after this is held by the first aperture of the oscillating sucker 10. The sucker 10 is oscillated about a shaft 11 carried by lever arms 12 by cam-and-lever mechanism 16, 17, 18 and the lever arms are operated similarly by a cam 21 on the same shaft as the cam 18. The lever arms 12 raise the separated sheet and carry it into the grip of feed rollers 15. The sheets are carried on a support 31 fitted with adjustable pile guides for sheets of different widths. The support 31 is mounted on a carriage, 32 which moves vertically in guides in vertical side links 33, and the vertical movement is controlled by worm gearing 38 and a counterweighted chain 34. The horizontal movement of the pile support is obtained by mounting the links 33 on bellcranks 41, 43 connected by links 44 so as to give the links a parallel motion. A cam 42 acting on an arm 40 of one of the bell-cranks 41 effects the horizontal movement of the pile. As the sucker 10 oscillates on its shaft, the orifices therein are brought successively into operation. To prevent double feed a screw 55 overhangs the front of the pile, and a blast nozzle 57 blows air from the side under the separated sheet. In a modified form of suction device, it is carried by a parallel motion device adapted to give a sucker with one aperture only movement in a horizontal plane, and this device is itself mounted on a second parallel motion device to move the sucker in a vertical plane only.
Patent GB-314514-A (GB)
Abstract: 314,514. Mica Insulator Co., (Assignees of Coffey, J. M.). June 30, 1928, [Convention date]. Mica. - Apparatus for making mica sheets comprises a suction device for lifting mica flakes from a feeding device and depositing them on a conveyor, means for applying a binding agent between layers of the flakes, an oven for drying the sheets and batching or stacking means for the finished sheet, the whole operation being automatic. Mica flakes are fed by a feeding device 74, Fig. 1, to a box 22, whence they are sucked on to the gauze-covered mouths of funnels 17, by which they are conveyed and deposited on a travelling belt 32. The funnels are reciprocated by a rack and pinion gear driven by a motor 1 through a clutch controlled by a driven cam, whereby the funnels are arrested for a short time in the pick-up position. The funnels are connected through a telescopic joint 30 with a suction pump 23, the suction being controlled by a damper 31 in the pipe 29. This damper, Fig. 7, comprises a pivoted plate with an arm 34, to which is attached a weight 37 on a cord 38 tending to close the damper. As the funnels 17 are moved over the box 22, the arm 34 comes into contact with a stop 39 and opens the damper to full suction. On movement to the right, the weight 37 closes the damper until a latch 40 comes into contact with a projection on a plate 41 maintaining sufficient suction to prevent the flakes from falling. At the end of the stroke, an upstanding arm 43 attached to the latch 40, comes into contact with a stop 44, and lifts the latch clear of the plate 41, and allows the damper to close, whereupon the flakes fall on to the belt 32. After each pick-up, flaps in the bottom of the box are opened by movement of the funnels to return surplus mica to hoppers 88 whence a current of air from a blower 77 returns it to the feeder 74 which is also intermittently actuated by the movement of the funnels. The funnel carriage also carries means for depositing adhesive on the layer of flakes before the next layer is delivered comprising a tube 54, Fig. 10, with a series of valves 55 operated by a spring- held cam operated by a jointed arm 59, 60. On movement to the left, the arm 60 rides on a runway 62 on the side of the machine and opens the valves, until the end of the runway is reached, when the arm 60 falls, the spring 57 rotates the cam, and' the valves close. The number of layers in the sheet is controlled by the relative speeds of the funnels 17 and belt 32. The sheet covered if desired on one or both sides with paper &c. from rolls 72, 72a, is passed through an oven 2 to a batching roll 69, while the belt passes through a cleaning bath 71. In a modification, the sheet passes under a camoperated guillotine, and the cut sheets are stacked by being lifted by fingers on a shaft intermittently driven by toothed segments.

Filed: 1919-12-16
Abstract: 146,781. King, C. G. Dec. 16, 1919. Ear-rings.-The crescent-shaped ornamental bodies of ear-rings are made by inserting in a tube 11, Fig. 1, preferably of precious metal, a rod 10 shorter than, and fitting, the tube and compressing the assembled parts in a reducing machine to taper the tube from its centre to its ends, Fig. 2. The compression causes the core 10 to fill the shell 11 and forms a covering of precious metal at the ends 12. The body is then bent on an arbor into an incomplete ring ready to receive ornaments 14, Fig. 8, conical openings being drilled through the shell into the core to form seatings for the conical backs of the ornaments which are secured in the usual way by forcing the material of the shell over the edges of the ornament by a setting tool, the core 10 preventing the collapse of the shell. One end of the body is bifurcated and drilled to receive the ear wire 20 and its pintle 24, the underside of the other end of the body being provided with a cavity to receive the free end of the ear-wire.
