Title: Improvements in method and apparatus for washing rubber threads
IPC: B29D99/00
Filed: 1955-03-29
Abstract: 767,079. Washing rubber threads. UNITED STATES RUBBER CO. March 29, 1955 [May 24, 1954], No. 9106/55. Class 70. Rubber threads are washed to remove soluble salts therefrom by fixing a ribbon of threads lightly adhered together to a tape disposed lengthwise through a washing liquid, and advancing the tape and ribbon along a path through the washing liquid. The ribbon R of rubber threads is led through a tensioner 32 and stapled to the underside of the tape 20 which passes over an idler roller 21 and into a tank 10 through which a continuous flow of a washing liquid, e.g. hot water, is maintained from an inlet pipe 11 to a drain pipe 12. The tape 20 passes back and forth between rollers 13, 13<SP>1</SP> disposed beneath the surface of the washing liquid and leaves the tank via an idler pulley 22 to pass over idler pulleys 30, 28, 29, 31 and to return to the tank via the pulley 21. The tensioning of the tape 20 may be controlled by suspending a weight 24 on an idler pulley 25. The tape 20 is advanced through the washing liquid by the roller 13<SP>1</SP> which is driven by a motor 19. The tensioner 32 comprises a driven rotary drum 33 about which the ribbon R is held looped by two idler rollers 34, and the drum 33 is driven to advance the ribbon R at a speed less than the speed of the tape 20 so that the ribbon is tensioned in its passage through the tank. The tape 20 and the ribbon R are guided through the washing liquid by rake-like guides 36, 40 in the lower and upper runs respectively. The tape 20 passes between the ribbon R and the roller 13<SP>1</SP>, and on leaving the latter the tape and ribbon are turned 90 degrees counterclockwise as seen in Fig. 2, so that the tape 20 bears against the left pin of a pair 39 on each of the guides 36. After leaving the final guide 36 the tape and ribbon are again turned 90 degrees counterclockwise to dispose the ribbon R between the tape 20 and roller 13. On leaving the roller 13 in the upper run to the roller 13<SP>1</SP> the ribbon and tape are turned 180 degrees counterclockwise to dispose the tape 20 between the ribbon R and the fixed angle irons 41 of the rakes 40. The tape 20 thus passes over the roller 13<SP>1</SP> in firm frictional engagement therewith.

Abstract: 526,661. Knitting. SCHNEIDER, M. E., (trading as SCHNEIDER & REUTHNER). March 24, 1939, Nos. 9300 and 9301. Convention dates, March 24, 1938, and Dec. 17, 1938. [Class 74 (ii) ] Relates to the production of a twisted-loop purl fabric on a knitting machine with two opposed sets of needles, each of which needles carries a knitting yarn and is so curved that the yarn hangs clear on one side of the needle. The two sets are disposed at an angle which, preferably, is less than 15 degrees. The needles can be shogged, for knitting purposes, and can also be moved in vertical planes at right angles to the length of the machine. In Fig. 1 the needles 5 are shown in their uppermost position, at which stage loops 9 hang on the stems 10 and encircle loops 11. formed from yarns 1. The sides 15 of the loops 11 are hanging freely below the bent needle heads 5<SP>1</SP>. At this stage, the needles 6 have just cast off loops such as 12 and have been shogged to the amount of one needle pitch. Towards the end of the shogging movement, each needle 6 engages the side 15 of the appropriate loop 11, as a result of which the loops 11 are held by the needles 6 and new loops are formed from the yarns 2. The needles 5 are then retracted to form loops and so on. To facilitate casting-off, the needles during retraction may be slightly tilted. The loops of the fabric produced as above described extend horizontally. Selvages are produced by means of a plunger 18, Fig. 4, which moves thread 14. up to needle 6<SP>11</SP> disposed adjacent the outside needle 6<SP>1</SP> so that it is knitted together with the thread passing through 6". Patterns incorporating stitch transfer effects are produced by means of combs &c. By forming two or more thread openings in each needle, the production of reinforced fabrics or patterns with longitudinal stripes is rendered possible. The needles can be moved individually and consecutively to perform the knitting operation.
