Title: Improvements in and relating to apparatus for the drafting of fibres
IPC: D01H13/04
Filed: 1944-06-26
Abstract: 624,765. Drafting textile fibres. BRITISH THOMSON-HOUSTON CO., Ltd. June 26, 1944, No. 12081. Convention date, June 26, 1943. [Classes 120 (i), 120 (ii) and 120 (iii)] [Also in Groups XIX, XXXV and XXXVII] A textile drafting apparatus includes two pairs of drafting rollers and regulating means for controlling the speed relation between the two pairs of rollers in accordance with the density of a sliver as it passes through a flow tube having openings corresponding to the normal sectional area of the sliver and which is connected to a source of fluid, variations in the fluid pressure controlling the regulating means. Air from a  constant pressure source is supplied through a restricted orifice 29 to a pipe 40 communicating with a chamber 28c in a flow tube 28, through which the sliver 10 passes after being drafted between pairs of rollers 12, 13. Air is also supplied through a restricted orifice 34 to a pipe 35, carrying a needle valve 36 with an outflow to atmosphere and connected to the lower chamber of a diaphragm device 27 by a pipe 37 carrying another needle valve 38. The upper chamber of the diaphragm device is associated with the pipe 40 and the two diaphragms are connected by a yoke 27d secured to a rod 26 of a carbon stack 21, which is in electrical connection with motors 14, 16 driving the pairs of rollers 12, 13. Variation in the resistance of the carbon stack 21 effects' alteration in the relative speeds of the motors. Any irregularity in the density of the sliver 10 will affect the air pressure in the chamber 28c, with a corresponding pressure variation in the upper chamber of the diaphragm device 27, resulting in movement of the rod 26 to alter the resistance of the carbon stack 21. To eliminate the tendency for a hunting action to be set up the needle valve 38 is provided. A multichamber flow tube device 42 is connected to the constant pressure air supply to support the fibres and facilitate uniform drafting. A pressure indicating device, such as a Bourdon gauge 41, is connected to the pipe 40, this may be calibrated to indicate directly the density of the sliver. The apparatus may be adapted only to measure the fibre density. In a further modification, the flow tube device 28. is dispensed with and the multichamber flow tube 42 is adapted' to perform the functions of both tubes.

Abstract: 812,314. Welding by pressure. WESTERN ELECTRIC CO. Inc. April 16, 1957 [April 27, 1956], No. 12413/57. Class 83 (4). A hand tool for percussively welding a wire to an article comprises a movable electrode for gripping the wire and moving it axially in a predetermined direction with a predetermined portion of the end of the wire in advance of the electrode, mounting means for supporting the electrode for movement to advance the wire in said direction, means for holding the movable electrode in retracted position under stress for movement, when released by the holding means, in said direction from the retracted position and a fixed electrode carried by the mounting means for engaging the article adjacent a selected portion thereof, release of the movable electrode from its retracted position advancing the wire into percussive engagement with the selected portion of the article. The tool comprises a body 22 of dielectric material having a pistol grip 23, the movable electrode 27 comprising a rod 28 and a sleeve 29 slidable in a bore 26 in the body and in a dielectric liner 30 secured to a dielectric coated fixed tubular electrode 31 screwed to the body and locked thereto by a nut 32 which secures a terminal 33 to the fixed electrode. A radial jaw 35 on the forward end of the rod 28 has a curved surface for clamping a wire against a curved surface of a jaw 38 formed on the sleeve 29. The rod may be rotated in the sleeve to release or allow the entering of a wire between the jaws by a lever 43 fixed to the rod. Rotation of the sleeve is prevented by a key 40 on the sleeve engaging a slot 41 in the body and the jaws are urged together by a spring 44 engaging the key and lever. An adjustable spring 51 urges the electrode 27 forwardly and the electrode is held in and released from a retracted position by a trigger bar 52, slidable transversely of the body. In operation with charged condensers connected to the two electrodes, a pointed or wedge-shaped wire 17 is inserted in and gripped by the jaws 35, 38, and the lever 43 is moved rearwardly to retract the electrode 27. The trigger is moved transversely to engage the key 40 and hold the electrode retracted. The fixed electrode is moved to contact a terminal 19 and the trigger is moved to allow the key 40 to slide in a slot 58 in the trigger and thus carry the wire into percussive engagement with the terminal with discharge of the condensers to effect welding.

Abstract: 1,110,493. Photo-electric web inspection. MOUNT HOPE MACHINERY Ltd. March 22, 1966 [June 29, 1965], No. 12437/66. Heading G1A. [Also in Division D1] To determine any misalignment between the warp threads (longitudinal) and the weft threads (transverse) of a web travelling under tension, a castor wheel presses down on the travelling web to locally distort the threads causing the warp threads as they pass under the wheel to kink to the right or left of the local weft threads are skewed, in the undistorted web, relative to these warp threads: the castor wheel in following the direction of the kink indicates the direction and degree of the skew. The movement of the castor wheel may mechanically alter the inductance of a circuit to indicate the skew. But in a preferred embodiment shown in Fig. 5 the wheel 20 moves a shutter 54, which in the neutral position equally partially obscures the two differentially connected photo-cells 58, fed with A.C. whose output indicates the angle assumed by the castor wheel. Two such detecting heads may be positioned one on either side of the centre-line of the web and their outputs both added and subtracted to indicate respectively whether the weft threads are skewed or bowed. The phase of the respective signals indicates the direction of the skew and the direction of curvature of the bow.

Abstract: 109,970. Soc. Anon. des AciÚries cidevant G. Fischer. Sept. 25, 1916, [Convention date]. Couplings, automatic, convertible to non-automatic.- In a convertible coupling of the kind in which an automatic coupling is carried by a bolt on a non-automatic drawhook and held suspended in the operative position by a device resting on the drawhook, the supporting member 4, from which the automatic coupling 1 is suspended, is pivoted on the bolt 2 of the draw-hook 3 and rests on the point of the hook. In the construction shown in Figs. 1 and 2, the member 4 is notched at 5 so as to receive a bridge-piece 6 connecting two downwardly extending rods 7, 8 which, with surrounding springs 11 and lugs 9, form the suspension means for the coupling 1. By releasing the bridge-piece 6 from the notch 5, the coupling 1 can be dropped into its out-of-use position, and the member 4 can then be raised so as to allow the link of an ordinary screw-coupling to engage with the drawhook 5. The member 4 is cranked upwards near the bolt 2 so that it can be brought to the horizontal position again after the link has been inserted in the draw-hook. In a modification, the suspension means comprise a closed link for engaging the notch 5, a single-depending rod connected to the link, and a spring surrounding the rod. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification, Fig. 5 (cancelled), in which the coupling 1 is permanently supported by the member 4 which is formed with two lateral projections 4<1> having holes through which pass adjustably the headed rods 7, 8.
