Title: Improvements in or relating to tire tubes and method of making same
IPC: B29B15/02
Filed: 1948-04-06
Abstract: 648,998. Pneumatic tyres. FIRESTONE TIRE & RUBBER CO. April 6, 1948, No 9601. Convention date, June 16, 1947. [Classes 144 (i) and 144 (ii)] Double air-tubes of the kind comprising an emergency chamber fitted inside a main tube of larger cross-section are made by preforming both tubes in unvulcanized condition, assembling the tubes for jointing along the rimseating portions, and then vulcanizing the composite structure. As shown in Figs. 1 and 4, the inner emergency tube is first builtup by laying on a drum 10 successive plies 11, 12 of rubberized cord fabric, the cords in the two layers crossing, and a top rubber layer 13, the edges of these layers being stepped as shown. A. marginal strip of rubber 14 is then applied to overlap one edge of the assembled plies and a flutter-valve 15 fitted over a hole adjacent that edge. The structure is then folded, as shown in Figs. 2 and 4, to complete the tube formation. This is temporarily removed from the drum over which a rubber band 30 is laid to form the outer (main) tube. The pre-built tube 1 is then laid on the band 30 the edges of which are then folded over and seamed to the exposed periphery of the tube 1, as seen in Fig. 7. A main inflating-valve 33 leading to the tube 1 is then fitted. The completed tube is finally placed in an ordinary jacketed vulcanizing-mould, steam being admitted intermittently to the inside of the inner tube to effect its partial vulcanization before the jacket is heated to effect vulcanization of the outer tube and the juncture of the tube bases.

Title: An improvement in or relating to automatic weft replenishing looms
IPC: D03D45/20
Filed: 1925-04-14
Abstract: 250,024. British Northrop Loom Co., Ltd., and Hollins, D. M. April 14, 1925. W e f t, cutting; weft - replenishing mechanism. - When weft replenishment is indicated, a shuttle feeler 1 is, as usual, moved rearwardly (towards the lay) and a movable cutting blade 14 thereon cooperates with a fixed blade to cut the weft end w extending to the selvedge and insert the cut end into the spring - pressed jaws 15 of a thread block. According to the invention, however, an auxiliary clamping device 16<1>, 17' is carried by but spaced away from the shuttle feeler to grip the cut end of weft and retain it as the shuttle feeler returns frontwardly to normal position, even though, as shown in Fig. 4, the cut weft end should be plucked out of the cutter owing to the contraction of the weft. The cut end is retained by the device 16<1>, 17<1> until it is dealt with by the temple cutter, or by the operative if no temple cutter is used. The clamping device may comprise a plate with a lateral part 16 upturned at 16<1> to co-operate with the offset portion 17<1> of a plate 17 secured to the movable cutter blade 14. When this is open, the weft end passes into the jaws formed between the under side 17<2> of the part 17<1> and the upper edge of the part 16<1>. When the blade 14 is actuated, these jaws are closed and grip the weft end. The rear end of the member 16 may be formed with an upturned projection 16<2> to prevent escape of the weft end. 250,044. McCarrel, A. H. May 11, 1925.

Patent GB-933521-A (GB)
Title: Hydraulically actuated well packers
IPC: E21B33/1295
Filed: 1962-03-13
Abstract: 933,521. Wells. BAKER OIL TOOLS Inc. March 13, 1962 [March 30, 1961], No. 9631/62. Class 85. A well packer A comprises a body 10 carrying a resilient packing 33, actuating means 17, 31 engaging the upper part of the packing, actuating means 54, 45, 35 engaging the lower part of the packing, hydraulicallyoperated means 55, 59 on the sleeves 31, 54 of the actuating means responsive to the hydrostatic head of fluid in the well for shifting the actuating means relative to each other to force the packing into contact with casing B, means 67, 75 for preventing the head moving the actuating means, and means 78 for shifting the preventing means to an inoperative position. Figs. 1, 1a show the packer attached to tubing C, 15 and being run into the casing. The packer is set by dropping a ball 85 through tubing C and applying pressure so that a pin 84 is sheared and a valve 82 is moved to open ports 80, 81 in the body and the sleeve 31, the ball then falling to the bottom of the well. Well fluid entering the ports moves a piston 70 to shear the pin 67 and move the sleeve 54 which is then moved upwardly by the fluid pressure on the end 59 to shift slips 45 into engagement with the casing. The movement of the piston permits movement of a key 75 under the action of the spring 78 to free the sleeve 31 from the body so that fluid acting downwardly on the piston 55 moves the sleeve 31 downwardly against the pressure of air in a chamber 58. The movement of the sleeves forces the packing into engagement with the casing and sets the slips to preclude downward movement of the packer. If the pressure of fluid below the packing tends to lift the packer movement of the packer is prevented by the increase in fluid pressure in the space 32, 31 which acts on the inner ends of pistons 23 to force wiskers 24 into engagement with the casing. A pin 105 on the sleeve 31 engages a shoulder 106 on the body to prevent contraction of the tubing C opening a port 93. The packer is released by pulling the tubing C sufficiently to shear the pin 95 and open the port 93 so that fluid flows into the chamber 58 to counteract the pressures acting on the sleeves. Further upward pulling on the tubing C may remove the packer from the casing. In a modification a connector 12a directly connects the tubing C with the member 17 and sleeve 31 as well as the body 10, the pin 105 being dispensed with. When the packer is to be released the tubing C is rotated, to disconnect the member 17 from the body.

Filed: 1937-04-05
Abstract: 498,380. Knitting. LIEBERKNECHT, R., and LIEBERKNECHT, K., (trading as LIEBERKNECHT, K., [Firm of]), and ROSSLER, K. W. April 5, 1937, No. 9682. [Class 74 (ii)] In knitting hose and half-hose in string formation upon a cylinder- and-dial machine, after completing a toe 508 and making some extra courses 510, run-stop courses 511 are knitted, the stitches are then cast off every alternate cylinder needle and these needles remain inactive while knitting proceeds as shown at 513, on the intervening cylinder needles until, at the commencement of the new stocking, rib needles are brought into operation in place of the inactive cylinder needles to knit a rib top 501. At the completion of the rib top, the loops are transferred from the rib needles to the alternate cylinder needles and plain fabric 503 is knitted using all the cylinder needles. At the commencement of the new stocking, the rib needles knit a course, then hold their loops while the intervening cylinder needles knit a number of courses, and are restored to activity, so that a welt 500 is produced. Transfer needles 132 are provided in the dial, and each needle comprises a portion having a shoulder 136. Immediately behind the shoulder 136 is a recess 137 from which extends a spring arm 138 forming a recess into which the cylinder needle 230 can slide. Fingers 130, one to each dial needle, are pivoted in the dial cap for controlling the needles, and are provided with operating butts 130d, 130e, engaged by actuating levers 280, 281. The fingers 130 may be used not only for projecting the dial needles for transferring the loops, but also for patterning purposes. The tension in the yarn may be varied by providing additional tensioning means which can be released under control of a pattern drum. A binder and cutter, Fig. 23, for the yarns is mounted upon the dial cap 129. A binder arm 363 is spring urged at 364 for holding a severed yarn and co-operates with a loose pivoted binder 365. The cutter 366 is normal spring pressed into cutting position and has an extension 370 connected by a link 371 to a lever engaging a pattern drum. The needle cylinder can be raised to increase the tension in the fabric when knitting the stocking top and the heel and toe. Specification 498,465 is referred to.

Title: Rebound damper for vehicle suspension springs
IPC: B60G13/04
Filed: 1929-03-26
Abstract: 310,318. Hack, E. April 23, 1928, [Convention date]. Vibration-dampers.-A vibrationdamper for suspension springs of vehicles consists of a drag-bar, attached at one end to the vehicle spring and sliding through a fixed and rigid clamp-box lined on its inner surface with friction material. The drag-bar is composed of a strip of spring steel bent to form two substantially parallel leaves F and G the bend forming an eye E for pivotal engagement with a member B attached to the suspension spring. Between the free ends of the bent strip, and attached to one leaf thereof, is a leaf spring H composed of one or more leaves adapted to spread the free ends apart. The clamp-box N, 0 through which the drag-bar slides is carried on a bracket K fixed to the chassis of the vehicle and is split to facilitate assembly, and also to provide a means for adjusting the pressure on the drag-bar, shims being placed between the abutting faces of the box. Above the eye of the drag-bar the leaves may be bent outwardly to spread them a greater distance apart than the inner faces of the clamp box, so that movement of the eye end of the dragbar towards the clamp-box progressively increases damping effect Movement of the drag-bar in the opposite direction is also progressively impeded, in this case by the spreader leaf spring increasing the pressure between the leaves and the clampbox.
