摘要： 450,409. Shuttles for circular looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., c/o British Celanese, Ltd., Spondon, near Derby. Jan. 16, 1935, No. 1483. [Classes 142 (ii) and 142 (iii)] A shuttle having a rotatably mounted weft spool 10 is provided with a freely movable braking member adapted, on deceleration of the shuttle, to move under the influence of inertia to apply a braking force to the spool. In the construction shown, the braking member comprises a lined shoe 21 carried by a lever 17 that is freely pivoted on the shuttle at 18 and is capable of swinging pendulumwise within the confines of a strap 22, the lower end of the lever carrying a weight 19 which is adjustable or replaceable for varying the braking force. Alternatively the swinging of the lever 17 may bring about the contraction of a brake band on to the spool or the introduction of a wedge between the spool and the shuttle body. When the deceleration ceases the brake automatically moves out of contact with the spool. The spool is retained on its supporting spindle 11 by a spring clip 16. Specification 446,270 is referred to.

摘要： 422,888. Circular looms. BRITISH CELANESE, Ltd., DREYFUS, H., 22, Hanover Square, London, and POOL, W., c /o British Celanese, Ltd., Spondon, near Derby. July 21, 1933, No. 21469/34. Divided out of 422,861. [Classes 142 (ii) and 142 (iii)] A circular loom employing one or more weft-spool-carrying shuttles is provided with automatic spool changing mechanism which is operable during the normal relative circular motion between the shuttle and the warps. The warp shedding mechanism in the vicinity of the exhausted shuttle is put out of action temporarily to enable the change to be effected and the replenished shuttle is allowed to make one idle pick around the warps. Shedding mechanism. Shedding of the warps is effected by pivoted levers 15, Fig. 2, each of which has an arm 34 for engagement with one or other of two cam tracks 37, 38 in a cam ring 39, a rotary movement being imparted to the latter by a shaft 42 which is driven by a constantly rotating ring 29. Shuttle propelling arrangements. A spindle 24, rotatably mounted in a bearing 25 on the ring 29, is provided with a pinion 26 for engagement with a stationary rack 27 which causes a rotary movement to be imparted to the shuttle propelling vane wheels 21. Shuttles. Each shuttle carries a weft spool 46, Figs. 1 and 8, in a casing 146 which is detachably secured to the shuttle body by spring clips 47. The weft is unwound from the spool by a freely mounted guide arm 48 and proceeds through a centrally located passage 50 and thence to a guide hook 51 at the base of the shuttle. Each spool has a radial bore 57 containing a plunger 56 which, under pressure of the weft on the spool, holds a ball 59 in locking engagement with a spring urged plunger 61 disposed coaxially with the spool and carrying a button 62. Initiating weft replenishment and positioning the the warps therefor. On exhaustion of weft the button 62 is projected into the path of a relatively stationary lever 64, movement of which rocks an arm 163, Fig. 4, of a latch 63 on the cam ring 39, and thereby releases a pivoted lever 67, movement of the latter under the action of a spring urged crank 70 operating a tract switch 73 to direct the warp threads, through their shedding levers 15, to the rear of the shuttle. Spool changing mechanism. Continued rotation of the cam ring 39 brings outwardly projecting teeth 72 on the lever 67 into engagement with a pin wheel 75 on a shaft 76 which, during the course of half a revolution, operates a crank 78, Fig. 6, and rocks a double bell-crank lever 83 to release a spool extractor 86, the latter being then pushed towards the shuttle 19 by a spring urged double armed lever 87 and under the guidance of a link 88 extending from a member 184. The extractor 86 is provided with a claw 89 which grips the expelled button 62 of the exhausted spool and, as the shuttle 19 advances, a stop 91 thereon pushes the spool and extractor away from the shuttle towards a shoot 53 into which the spool is finally projected. On the forward movement of the extractor 86, the anti-clockwise movement of the lever 87 withdraws a spool injector 92 and a bunter 94 thereon form the discharge opening of a magazine 54, thereby allowing a fresh spool 90 to emerge and become engaged with the injector claw 93. The subsequent clockwise movement of the lever 87, produced by the action of the shuttle on the extractor 86, causes the latter again to be engaged by the catch 85 and the injector 92 to place the fresh spool in the path of the clips 47 of the approaching shuttle. An adjustable stop 192 on the lever 83 facilitates adjustment of the operative positions of the extractor and injector. Controlling shedding in looms employing a plurality of shuttles. Since a replenished shuttle is withdrawn from the warps for one revolution, means are provided for causing a following shuttle to make an ineffective circuit in order to prevent the formation of double picks in the fabric. This is effected by a pivoted lever 98, Fig. 1 and 4, which, on being rocked by a cam 80 on the shaft 76, during the initial rotation of the pin wheel 75, resets the lever 64 so that it may engage the following latch 63 and thereby operate a tract switch 74, Fig. 1, to move the warps 18, Fig. 2, to the rear of the second shuttle. With the continued rotation of the ring 39, the pin wheel 75 is rotated by the second lever 67, so as to reposition the catch 85 in the path of the extractor 86, and allow the member 64 to assume its normal position. Further advance of the replenished shuttle 19 and the cam ring then brings the toothed lever 67, associated with the shuttle 19, into engagement with a second pin wheel 103 rotation of which projects a rod 107 into the path of a pivoted catch 108, Fig. 1, on the shuttle. When the catch 108 is rocked, a pivoted guide arm 111 on the shuttle is oscillated to engage the weft extending from the fresh spool to an anchoring point 65 and convey it to a point adjacent the fell of the fabric. The push rod 107 is withdrawn by the action of the second catch 67 on the wheel 103. On completing one revolution around the outside of the warps, the shuttles 19, 97 are again admitted into the warps through pins 112 on their respective levers 67 engaging a stationary member 77 and thereby resetting the track switches 73, 74. Take-up mechanism. The speed of the take-up mechanism may be reduced during the ineffective strokes of the replenished and the following shuttle. Severing weft ends. A cutter 116, Fig. 2, located adjacent the spool changing mechanism, and operated by a projection 119 on the ring 29 severs the weft extending from the ejected spool and that left on the surface of the warps as the result of idle picking. Weft feeler arrangements. Relative circular motion between the shuttle and the warps may be brought to an end by the feeler mechanism described in Specification 396,758.

摘要： 422,861. Circular looms. BRITISH CELANESE, Ltd., 22, Hanover Square, London, POOL, W., c/o British Celanese, Ltd., Spondon, near Derby, and DREYFUS, H., 22, Hanover Square, London. July 21, 1933, No. 20585. [Classes 142 (ii) and 142 (iii)] A circular loom employing one or more weft-spool-carrying shuttles is provided with means for replenishing each shuttle with weft, on exhaustion of the spool, in the course of the normal operation of the loom such replenishment being effected at one or more gaps provided in the cylindrically arranged warp threads. Each shuttle 19 is provided with a rotatably mounted spool 41 operatively connected with a train of gears 45 the leading pinion 44 of which projects from the body of the shuttle into the path of a segment shaped rack 42 located at a gap A in the warp threads 10. When the shuttle emerges from the warp threads, weft yarn 35, extending from a guide 40 to a point adjacent the fell of the fabric, is engaged by the spirally slotted inner flange 47 of the spool and, during subsequent engagement of the pinion 44 with the rack 42 in the passage of the shuttle across the gap, a length of weft is withdrawn from a stationary package 36 and wound on the spool 41. On re-entry of the shuttle into the warps, a cam 52 on the rack 42 rocks a pivoted lever 54 on the shuttle and thereby raises and lowers a pivoted arm 58 which engages and moves to the fell of the fabric, the weft extending from the spool to the guide 40. The downward movement of the arm 58 brings the weft into a spring tension device 64 carried thereby and into a guide slot 62 on the shuttle. As the shuttle passes within the warps, a cam 65, Fig. 7 on a rotating cam ring 66 engages a relatively stationary plunger 67 and oscillates a finger 70 so as to depress the weft below the fell of the fabric and into engagement with a toothed weft cutter 74. Subsequent operation of the latter by the cam 65 severs the weft from the supply. The length of weft extending from the cutter 74 to the guide 40 is wound on an auxiliary spool 50 during subsequent replenishment of the same or a following shuttle. The length of weft laid in the fabric is maintained under tension during unwinding by the resistance of the train of gears 45 and the tension device 64. The shedding of the warps is effected by pivoted levers 16 which are rocked by the action of a rotating cam ring 27 on their arms 24. Specifications 396,757 and 413,376 are referred to.

摘要： 374,956. Weft-inserters for looms with' stationary weft supplies. BRITISH CELANESE, Ltd., 22, Hanover Square, London, POOL, W. and LATHAM, L., of British Celanese, Spondon, near Derby. March 19, 1931, No. 8542. [Class 142 (ii).] In a dummy shuttle or weft carrier for use in shuttleless looms, the passage between a weft-engaging horn and the body of the shuttle is formed with a constriction which readily permits the passage of a weft loop during its engagement with the horn but prevents the loop from springing out after its engagement. The constriction may be formed by providing on the horn or on the body of the shuttle a tooth 21, Fig. 1, which may be arranged to enter a groove in the complementary member, as shown in Fig. 9, the latter construction causing a kinking of the thread as it passes into the horn. In a modified form, a tooth 28, Fig. 8, provided on the base 15 of the horn, projects into a hole 29 on the shank of the horn and prevents escape of the loop after being caught and led to the grooved base of the carrier.

摘要： 300,593. Vickers, Ltd., and Pool, W. May 16, 1927. Governing and regulating.-A valve device for use in connection with metering pumps used in apparatus supplying cellulose acetate or other cellulose solution to extruding heads for the formation of artificial silk threads comprises a piston valve controlling a supply under pressure and actuated by a piston subject to the pressures in the conduits leading to and from a pump-like element preferably of the gear type and adapted to open further the inlet when the outlet pressure increases so as to restore the balance of pressure. The piston valve B has three bands b , b , b', the bands b , b being provided with apertures b for the passage of fluid, The pressures in the conduits A', A leading to and from the gear pump A which is driven by wheels a, a act on the valve so that under normal conditions the band b leaves the inlet port for high pressure fluid slightly open. If the outlet pressure rises the inlet is opened wider and if it falls the inlet is further reduced. In the event of the outlet pressure exceeding the pressure in the conduit B , the valve rises so that the band b closes the inlet and the band b passes above an annular groove b to short circuit the gear pump. Reference has been directed by the Comptroller to Specification 293,325.

摘要： 632,697. Making slivers, rovings and yarns of stapled fibres. POOL, W., and McGILL, A. April 30, 1947, No. 11620. [Classes 120 (i), 120 (ii) and 120 (iii)] A process for the conversion of a bundle of continuous filaments into a continuous product made of staple fibres comprises gripping the filaments of the bundle at two spaced points, forwarding the gripped filaments from the first of said points towards the second at one linear speed and from the second point onwards at a greater linear speed so as to stretch the filaments between the two points, and at a third point, between the two points subjecting the filaments to sharp and rapidly repeated impact so as to break, at said third point, some of the filaments that have been stretched to a degree substantially short of that at which they would break under tension. Slivers 1 from cans 3 are led to flattening bars 7 and thence between tensioning roller sets 8, 9, 10. Between roller pairs 12, 13, 19, 20, which may include leather &c. belts 16, 21, the flattened sliver is subjected to a " draft of 5 or more and while tensioned below its breaking point, is subjected to impact by a straight edge 26 vibrating at 2,000 oscillations or more per min. The impacts break the filaments of the sliver and form a continuous stapled product which is subject to a false twisting device at 30 and lubrication at 31. After passing through a further false twisting device 38 and a "stuffing- box," the crimped sliver is collected in a rotating coiler can 44. In a modification, the stapled sliver is fed by rollers from the false twister direct to a flyer for winding it on a bobbin as a roving. In a further modification, the stapled product is fed direct to a ring spinner for winding on a bobbin as a coarse yarn. Specification 582,949 is referred to.

摘要： A jet assembly for the extrusion of artificial filaments and like products comprises a jet having extrusion orifices therein, and a plate finely spaced from the inner surface of said jet, said plate being perforated, at a distance across the face of the plate from any of said orifices, for the passage to the inner surface of said jet of material to be extruded. The plate may be spaced from the jet by means of a washer or by the provision of integral projections on the plate or inner surface of the jet. The jet must be of sufficient thickness to withstand the pressure developed, and in order to obviate long holes forming the orifices, the inner surface of the jet is recessed at the points where the orifices are formed. The complete assembly may be used for the melt-spinning of polyamides. As shown, a steel disc 1 is drilled with six holes 2 on centres equally spaced from the centre of the disc, and at the bottom of each hole and coaxial with it is a spinning orifice 3. A washer 4 separates the disc from a second hardened steel disc 5 having a central hole 6. 1, 4-5 are clamped together by means of a heavy internally flanged nut 7 against the end of a flanged screw-threaded pipe 8 which supplies the spinning material to the assembly.

摘要： 542,326. Artificial filaments. TAYLOR, W. I., and POOL, W. July 2, 1940, No. 11150. [Class 2 (ii)] In the dry-spinning of artificial filaments. the spinning jet is first filled with a liquid compatible with the spinning solution and is then applied, while still full, to the source of supply of the spinning solution. Spinning then proceeds, optionally with the preliminary application of vibrating pressure to the surface of the spinning jet, to assist in freeing the orifices. As shown, the spinning jet fitting 4, Fig. 2, has a flanged metal disc 6 with orifices 7 having a layer of filter material 9 and a perforated plate 10. The upper part of the jet fitting contains a ball 13, which is operated by a spring 14 to fit the conical seat 12 and to close the opening therein when free to do so. The jet fitting is attached to a member 61 which is screwed on to the supply pipe 17 for the spinning solution and has a ball valve 19 operated by gravity. The nut 15 is unscrewed to release the jet fitting from the supply pipe, and the fitting is connected to the header 25, Fig. 4, through a pump 24 so that spinning solution or some other compatible liquid is forced through it for a period. It is then removed, the liquid being retained by the ball valve 13, and connected again to the supply pipe 17, which has been kept closed by the valve 19, and both valves are opened by the apertured washer 22, which presses both balls 13, 19 from their seats. Normal spinning then proceeds. A small pneumatic tool 26, Fig. 5, can be connected by a flexible hose 27 to an air supply. The tool has a wooden peg 29 which can be applied to the face of the jet to cause rapid vibration and so clear the orifices of obstructions.

摘要： 520,084. Forming staple fibre yarns or like products. POOL, W. Oct. 10, 1938, No. 29288. [Class 120 (ii)] A staple fibre yarn or like product is formed by feeding a succession of flat wide groups of separate fibres in the direction of the length of the fibres to the end of a rapidly rotating support that lies transverse to the direction of feed of the fibres with its axis close to the plane in which the groups are fed so that different fibres in each group are taken up at different points on the support by the previously fed fibres and drawn away continuously along the axis of rotation to form the staple fibre yarn &c. by the twisting together of the successive groups of fibres by the rotation of the support which extends axially from the yarn beyond any point at which the fibres meet the support; the yarn produced may be drawn away through a rapidly rotating twist tube so as to effect the rapid rotation of the tail of the yarn which constitutesthe support. As shown, a continuous filament yarn 1 is drawn from a package 2 of the kind formed by the method described in Specification 504,399 and passes through ejectors 11, 15, supplied with compressed air from a header 13 and which loosen and separate the filaments from one another and form them into a flat band which, as it emerges from the nozzle 17, is pressed periodically by deflector rods 21 into engagement with a continuously operating cutter 18 of the hair-clipper type. The ends of the filaments are blown by the stream of air through the nozzle 17 along a diverging channel plate 40 open at the top, the ends of the filaments becoming more separated and at the end of the plate encountering the tail 41 of the yarn 26 being formed, this tail extending beyond any point at which the filament ends meet it so as to provide the rotating support therefor. The ends of the filaments are urged into contact with the tail by a current of air induced by suction through perforations at the end of the plate 40 and the tail of the yarn 26 is rapidly rotated and twisted by a twist tube 25 formed and supported as described in Specification 519,995, and as the free ends of the filaments become entangled with the rapidly rotating tail of the yarn 26, the filaments are cut by the cutter 18 and the cut ends are subjected to a current of air through perforations 60 in the side of the plate 40 and blown sideways through a flat covered passage 65 into a tail pipe 63 connected by a conduit with the suction conduit 46 communicating with the perforations in the end of the plates 40. The staple fibre yarn emerging from the twist tube passes to a winding device 31 ... 34 by which it is formed into a package 35. In a modification the twist tube is replaced by a short needle-like spindle and the rear ends of the cut fibres, instead of the leading ends, may be engaged by the rapidly rotating support. The filaments may be electrified by passage through a gate tension device as described in Specification 504,400 so as to facilitate their separation. Specifications 484,190 and 489,272 also are referred to.

摘要： 489,272. Forming staple fibre yarns or like products. POOL, W. Oct. 21, 1936, No. 28593. [Classes 120 (ii) and 120 (iii)] Staple fibre yarns or like products are formed by feeding a substantially twistless bundle of associated continuous filaments towards a rotating drum, separating the filaments of the bundle from each other at the end of the bundle, obtaining from such separated filaments a succession of groups of separated fibres of predetermined length by a cutting operation, holding each group of cut fibres to the peripheral surface of a rotating drum by suction, and withdrawing the succession of groups through a passage to the axis of the drum, the rates of feeding and withdrawal being such that the ends of successive groups overlap and the twist imparted by the rotation of the drum unites them into a continuous twisted product. A number of 'separate successions of groups may be twisted on one drum and collected as a single product, or at least one may be led through one passage and the remainder through another and respectively withdrawn from opposite ends of the drum so as to form separate products. The fibres may be of cellulose acetate or other organic derivative of cellulose. As shown in Fig. 1, a bundle of filaments 24 having little or no twist is withdrawn by feed rollers 28, 29 through a gate tension device 27 and delivered by a compressed-air feed-device 30 in an open state to cutting means from which they pass to the drum 1 and through the tube 16 to winding-up means 57. The drum is surrounded by a casing 22 which is slotted for the passage of the material, and suction through holes surrounding the flared opening of the tube and in the surface of the drum is effected by a conduit 15 and an adjustable valve 13. The feed device 30 is supplied with compressed air from a conduit 34 which serves to eject the filament at intervals and to separate them in the form of a flat band. Severing-means 41, Fig. 8, is arranged between the nozzle of the feed-device and the drum, and is operated by a cam 43 to cut the filaments obliquely to the direction of feed when they are depressed by arms 45 operated by a cam 47. A cam 39, Fig. 6, opens and closes a valve 38 in the feeddevice 30 and is mounted with the cams 43, 47 on a shaft 40 so that filaments are fed forward, severed, and engaged by the drum 1 in succession, the newly cut ends of the main supply being automatically withdrawn into the feed-device from the severing-means. The gate tension-device 27 is made of metal and one or both of the feed rollers 28, 29 may be covered with guttapercha so that an electrostatic charge is generated and maintained in the filaments whereby their separation at the feed-device is facilitated. This effect is maintained by applying french chalk to the rollers and by traversing the tension-device relatively to the rollers, for which purpose it is mounted on a pivoted arm 60. The pressure of the tension device is regulated by a spring-controlled wire 69 connected to the movable gate and, for this purpose, operating as a lever pivoted at a. A feeler 74, Fig. 11, is adapted upon breakage of the yarn to engage a rotary tooth 76 and thereby to release a detent 77, whereby a vertical rod 81 is released and moved by a spring 82 so that an arm 89 is operated to disconnect the drive of the drum, 'the cradle 93 of the roller 28 is raised by the lever 92, and the tail 72 of the wire 69 is operated to lock the tension device to prevent passage of the filaments. A cam 85 is arranged to engage a roller 84 on the feeler 74, when it is moved by the tooth 76, so as to tilt the feeler into a position to facilitate re-threading. Specification 484,192 is referred to.
