Title: An improvement in or relating to wire-drawing machines
IPC: B21C1/12
Filed: 1947-12-02
Abstract: 655,569. Drawing wire. BARTIN, Ltd., and TINSLEY, H. Dec. 2, 1947, No. 31794. Drawings to Specification. [Class 83 (iv)] In a wire-drawing machine the drawing- drum or each of the drums after the first if there are more than one is driven by a separate hydraulic motor controlled by a valve which is actuated by the pull on the wire passing on to the drum to vary the speed of the motor in accordance with the variation in the pull. The wire before reaching each drum may pass over slidable or otherwise movable pulleys, the movement of which is yieldingly resisted by springs, balance weights or hydraulic cylinders and which actuate the control valve. In a modification the dies may be slidingly mounted in a guided track to actuate the control valves.

Title: A device for packing or stuffing tubes filled with sand or the like by means of knocking or beating
IPC: B21D9/16
Filed: 1923-12-19
Abstract: 223,088. Hoffmann, J. Dec. 19, 1923. Packing sand into tubes.-Relates to apparatus for packing tubes filled with sand by beating. According to the invention, the hammers which effect the beating carry out a simultaneous rotary and longitudinal movement in respect of the tube, which is stationary. The tube T, Fig. 4, to be beaten is secured in a bearing 5, Fig. 1<a>, by screws 6 and in an upper guide. A hammer support 11 is adapted to be rotated upon a support 8 by a bevel gear 27 on a shaft 26. The shaft 26 and support 8 is movable vertically by an arrangement of ropes and a winding drum. The hammers 35, Figs. 3 and 4, are carried in casings 31 and are adjustable in sleeves 34 connected to operating levers 42 pivoted at 43 on a rotary disc 30 forming part of the hammer support 11. Cams 48 with curved guiding surfaces 58 are mounted on a non-rotating guide disc 46 and are adjustable towards and away from the centre by bolts 50 passing through curved slots 51 in a regulating disc. In operation, the hammer support is rotated relatively to the cams 48 and their support, and each hammer is drawn back against the action of springs 38 and released suddenly. The forward part 36 of each hammer strikes the tube T through an opening 37. The force of the blows is regulated by adjusting the position of the cams 48. While the hammers and their supports are travelling round the tube, the whole device is moved vertically. Reference has been directed by the Comptroller to Specification 3845/74.

Title: Improvements in and relating to the vulcanization of rubber articles
IPC: B29D30/06
Filed: 1920-11-11
Abstract: 175,383. White, A. E., (Goodrich Co., B. F.). Nov. 11, 1920. Vulcanizing tyres; presses. - Tyres and other articles are treated with steam under pressure in partly open moulds, as shown in Fig. 3, until the rubber is softened and strains in the fabric base are eliminated. The steam pressure is then released to cause moisture condensed in the moulds to evaporate, mechanical pressure is applied to close the moulds, and steam is re-admitted to the press till vulcanizing is complete. A tyre, for example, is first heated to 287‹ F. for 20-25 minutes, and then vulcanized at 297‹ F. for 30-15 minutes. In a hydraulic press suitable for carrying out the process, the cover 22 is unlocked by partly rotating it, whereby rods 31 depending from it engage with projections 26 on the platen 25 so that the cover may be raised by means of the ram 19. The upper part of the stack of moulds 12 is supported on a shelf 33 which is free to move upwards during pressing.

A pattern wheel for a circular multifeed machine includes at least one series of pivotally mounted jacks, selectively moved between operative and inoperative positions by an electro-magnet as they approach the needle butts. In one embodiment the wheel comprises two series of jacks 19, 19', mounted in slots defined by magnetisable spacers (22), and acting alternate needle jacks 10. The jacks are pivoted to an operative position, at one side of the slots, as the wheel passes a permanent magnet 23. An electromagnet 24 then influences selected spacers which attract the jacks approaching the magnet, swinging them to an inoperative position at the other side of the slots. Operative jacks push needle jacks clear of a raising cam 8. In a second embodiment (Figs. 4, 8 not shown) the slots are defined by cranked elements (34) bearing locking fingers (37-8) and deflecting cams (35-6). Immediately adjacent a selecting electromagnet (45, 45) the elements are raised and deflect the jacks to an inoperative position. Selected jacks are pulled back to an operative position by the magnet and immediately locked by the fingers as they are lowered again. Energisation of the electromagnet is controlled by a photoelectrically scanned punched tape or film and synchronised to the operation of the machine.

Abstract: 1,077,098. Roller conveyers. H. D. JACKSON CO. Ltd. April 29, 1966 [July 31, 1965], No. 32872/65. Heading B8A. [Also in Division F2] In a conveyer comprising a series of freely rotatable rollers one or more of the rollers may comprise a pivoted control member 14 normally held by gravity clear of a stationary but adjustable stop abutment 18. When a predetermined rate of rotation is exceeded by the roller the member 14 is moved by centrifugal force into engagement with the abutment 18 to arrest rotation of the roller. The member 14 then swings clear of the abutment and the roller is free to start rotating again. The rate of rotation at which the abutment 18 comes into operation depends on its angular position which can be adjusted by varying the setting of a plate 21 carrying the abutment. The member 14 may be loaded by a light spring. In a modification, the free end of the pivoted member may have a pad of friction material which may be brought into engagement with a surface on the adjustable plate to act as a brake.
