Title: Improvements relating to devices for applying a marking in stitching to a garment, piece of cloth or like article
Inventor: TILLETT STANLEY HORACE
IPC: D05B35/12
Filed: 1948-06-24
Abstract: 640,756. Sewing-machines. TILLETT'S COTTON MARKING MACHINES, Ltd. June 24, 1948, No. 17082. [Class 112] Feed by clamps. - An attachment for reproducing in stitching letters or any other marking comprises a tracing point to be guided by hand over a pattern, a work holder, and pantograph means connecting the workholder with the tracing point so that it will reproduce the inovement of the point, the work - holder being guided so as to prevent angular movement thereof. In the embodiment shown, a work-clamp 33 is secured to a plate 51 mounted on a base-plate by means of crossed slides, which permit universal horizontal movement of the plate without rotation, and connected by a pantograph 12, 13 pivoted to the'base-plate at 11 and the plate 51 at 19, with a pattern tracing point 20 movable by an adjustable handlever 21 over a pattern device 10 on the base-plate. The pantograph and the plate 51 and its mounting are enclosed in a cover 73 shown chain-dotted; the base-plate is adapted to be secured by screws to the sewing-machine in any suitable position with a needle-hole 67 in the work-clamp base under the needle of the machine, and is recessed on its underside to clear the feed-dog. An opening in the base-plate, with a cover 78, gives access to the bobbin of the machine, and the clamp 33 is fixed to the plate 51 by a finger screw 65 and locating pins, allowing easy removal of the clamp from its position obstructing the opening. The work-clamp comprises a base with a post 46 to which are'pivoted arms 38, carrying a clamping member 35, and cams 48, with an operating lever 44, for forcing the member 35 downwards; an auxiliary changing member 37 slides on pins 50 on the base and is pressed downwards by leaf-springs 43 fixed to it and bearing on the undersides of the arms 38, to hold the work before the clamp proper is closed. Both clamping members have apertures 62 to allow movement without obstructing the needle, and suitable stops are provided to limit the movements of the slides carrying the plate 51 or of the pantograph members, in accordance with the size of these apertures. The pattern device 10 comprises casing with an opening 80 into which can be fitted detachable plates carrying signatures or other patterns to be copied and beneath which slide bars 3 bearing series of letters or numerals enabling any described combination to be built up. The bars 3 have fingerknobs at one end, and are held in any set position by spring catches on their undersides engaging series of notches in the base of the device; the catches being adjustable along the bars 3 to allow of exact positioning of the bars; a clamp 83 secures the slides in position when set.

Abstract: 1,009,182. Washing machines. E. SULZMAN. May 3, 1963 [Jan. 5, 1963], No. 17506/63. Heading D1A. A tubular double drum washing machine comprises a perforated inner drum 12 which is rotated on a series of bearing rails 13 arranged between it and an outer drum 10. These rails, which extend wholly or partly around the inner drum and may be fixed thereto or to the outer drum or may be loose and located longitudinally, form a series of separate compartments for the washing liquid between the two drums. The drums are adjustably inclined so that washing fed by a conveyer belt 26 into a hopper 25 at a charging end 17 passes through the inner drum and through successive washing regions to a discharge end 18 where it may be removed by a conveyer belt 38. Baffles 40 are provided along the inner drum to further define the washing regions and fresh water is introduced at 44a near the discharge end and the dirty water overflows at 31 near the charging end so that a centre-flow action is obtained. Soap bleaching agents, alkali and heat are supplied at different points 44b-e and a soaking or pre-washing is effected in the first region at the charging end for which rinsing water discharged with the washing at 44 is used which is then discharged at 32. The charging of the washing may be assisted by water supplied to the hopper 25 by a pump 27 from the soaking or pre-washing region. Disinfectant may be added during this first operation. A baffle plate 41 is provided at the discharge end and extending below the water surface to prevent the discharge of steam and a syphon like charging hopper may be provided for the same purpose.

Abstract: 550,041. Finishing fabrics. YORKSHIRE DYEING & PROOFING CO., Ltd., CROSSLEY, W., and MASON, F. E. June 17, 1941, No. 17775/40. [Class 42 (i)] Relates to a process for shrinking textile fabrics upon finishing machines such as the Palmer type wherein the fabric A, before passing around a heated drying cylinder B of large diameter against the surface of which it is pressed by a thick endless travelling blanket C, passes with the blanket over a roller or bowl D, the outer surface of the blanket first expanding, from position 1 to position 3, and thereafter contracting, from position 3 to position 2. The adherence of the fabric to the blanket is assisted and shrinking of the fabric ensured by air or steam blown from a hood E so as to impinge upon the fabric as it passes from position 3 to position 2. The inner face e of the hood E may be open as shown. or may be perforated. The hood E may be replaced by one or more pipes with nozzles to direct the air or steam on to the surface of the fabric. The air may be heated and/or humidified before being blown on to the fabric. To increase the shrinkage one or more additional rollers may be arranged in front of the roller D.

Abstract: Polymeric dimethyl silicones are prepared by hydrolysing a dimethyl silicon dihalide, recovering the hydrolysis products, fractionating them, and then treating the fraction which boils below 200 DEG  C. at 20 mms. with sulphuric acid to convert the polymeric dimethylsilicones so produced into viscous liquid products having a boiling range above 200 DEG  C. at 20 mm. pressure. The preparation of the polymers boiling below 200 DEG  C. at 20 mms. pressure is fully described in Specification 586,188.  In examples: (1) sulphuric acid is added to a mixture of the dimer and the tetramer of dimethyl silanone obtained by fractional vacuum distillation of the hydrolysis products of dimethyl dichloro silone at 140 DEG  C. at 0.2 mms. pressure.  The reaction mixture is shaken for 15 hours to produce a viscous product; (2) the tetramer obtained as in example (1) is treated with sulphuric acid in ether solution.  The compounds of the invention are particularly suitable for lubrication purposes under oxidizing conditions at elevated temperatures.  Specifications 542,655 and 586,187 also are referred to.
