摘要： 581,424. Securing pulleys on shafts. PLATT BROS. & CO., Ltd., and CLEGG, J. K. May 2, 1944, No. 8238. [Class 80 (ii)] [Also in Group XXX] The loose pulley b of a fast and loose system f, b is journalled on a capped sleeve c supported at its inner rim on a shoulder of the shaft d and at its outer end by a screw k threaded into a hole m formed concentrically in the end of the shaft. The cap is flanged at e to retain the loose pulley in position. The device is particularly applicable to the re-mounting of a pulley upon a worm shaft end, such as occurs in carding machines. In such case the pulley is rebored to fit the sleeve, and its boss is preferably reinforced by a ring n, suitably located at its inner end to form a thrust bearing against the fixed pulley f. The screw k may be shouldered as at j, j', and the inner rim of the sleeve is recessed at h to take over the end of the key i of. the fixed pulley. The pulley bearing surface may be hardened, and the sleeve c, be of brass or phosphor-bronze.

摘要： 580,227. Tying packages. POWER & SONS, Ltd., F. A., PADMORE, J. N., PLATT BROS. & CO., Ltd., and BASSINDALE, I. B. June 21, 1944, No. 11831. [Class 45] An automatic tying machine which may be of the kind described in Specification 523,830 having clutching and declutching means controlling the drive to a rotary wire training device has additional means connected with the control pedal of the clutch striking gear whereby the declutching and stopping action is effected at once if the foot of the operator is removed from the control pedal. The driven element 53 of the clutching means is rocked by a yoke 51 keyed to a yoke shaft 52, into engagement to the right (Fig. 1) with the driving element (not shown) or to the left with the stationary holding element (not shown). The driving clutch element is engaged (to rotate the wire training device) as in Specification 523,830 by the treadle controlled rod 56 drawing down lever 58 which engages the arm 64 of the yoke shaft 52. The additional declutching means comprise an additional rod c coupled at its lower end to the treadle (Fig. 3) and at its upper end by a yoke b to a lever a freely pivoted on a shaft 61 and to a lever e. The lever e is in slotted engagement with a pin h on an arm i keyed to the yoke shaft 52. If the operator's foot is removed from the treadle the yoke b is urged upwards by spring means (not shown) and, by means of the link e and arm i, the clutch element is moved to the left into engagement with the holding element thereby stopping and holding from movement the wire training device. The slotted end of the link e allows it an idle motion on the downward movement of the treadle. To prevent accidental slipping of the foot from the foot pedal lever 54 (Fig. 3) it is provided with a raised toe piece k and side pieces m.

摘要： 523,000. Lifter-motions for spinning &c. machines. PLATT BROS. & CO., Ltd., HUGHES, J., and WATSON, W. H. Dec. 20, 1938, Nos. 36990/38 and 1278/40. [Class 120 (ii)] Mechanism for lifting the ring-plate or like yarn guiding devices and the lappet plates of ring-spinning and like machines, comprises means in operable connection with the usual lifter bar for imparting a vertical movement to the pokers of the ring-plates through flexible connections and means for simultaneously imparting a proportional vertical movement to the pokers of the lappet-plate ; the parts are returned to the initial positions by gravity and both of the means for imparting vertical movement are independently adjustable to vary the extent of lift without any change of parts. As shown a metal band or tape 34 is adjustably secured at one end to the lifter bar 33 with its other end 37 secured to a pulley 29 on a short shaft 25 mounted in a bracket 23 secured to the spindle rail 11 ; a second pulley 30 on the shaft 25 spaced from and integral with the pulley 29 is connected by another band or tape 40 with pin 41 adjustably fixed in a bracket 44 extending from the poker 13 of the ring rail 12. A lever 54 pivoted on a pin 53 in the bracket 23 carries a bowl 55 engaging a cam 32 fixed to the pulley between them and the free end of the lever carries a bowl 56 engaging a collar 57 on the poker 18 of the lappet plate 17. In a modification the second pulley and cam are dispensed with and the band 34 passes from the lifter bar over a guide pulley to the pin 41, while a block adjustably mounted on the lifter bar carries a grooved roller engaging between the limbs of the longer arm a slotted bell-crank lever pivoted in an extension of a bracket on the spindle rail with the shorter arm carrying a bowl engaging a collar on the lappet plate poker; the longer arm of the lever may be formed of a circular rod bent to an elongated U-shape with a leg adjustably fixed at each side of the pivot of the lever on the shorter arm thereof.

摘要： 510,626. Hydraulic loading of machine rollers. PLATT BROS. & CO., Ltd., and BRUCE, D. T. D. March 22, 1938, Nos. 8722/38 and 9012/39. [Class 69 (ii)] [Also in Group IX] Hydraulic means are used to apply pressure, which may be varied, to sized and other warps of jute &c. whilst being wound on a beam. The pressure-applying roller 31 is supported by rollers 29, 30 carried by levers 27 on a shaft 24 furnished with weighted arms 33 and with a hollow boss 36 with slotted extensions receiving slide blocks 37 on a cross peg 38 on the extension 21a of a hydraulic ram. This fits in a pressure chamber 18 fitted with packing and a gland 23 and communicates by a pipe 42 with one outlet of a three-way valve the inlet of which communicates with a mains supply, whilst the other outlet communicates with an exhaust pipe. A pipe 44 leads from this to the chamber and is equipped with a pressure gauge and a spring- loaded pressure valve. The method of using the apparatus to first apply and then release and afterwards reapply pressure is described, a handle 39 being used to turn the shaft 24 to push the ram inwards and expel pressure fluid from the chamber 18 when required. An additional valve may be provided in. the main line and a pressure in excess of the mains pressure may be built up behind the ram. Two or more rams may be used. Two pressure rollers fulcrumed in shafts coupled together and acting on the front and rear of the beam respectively may be used. The warp 16 passes to the beam between draw and nip rollers over measuring and tensioning rollers 14, 15. In a modification described, the pressure chamber communicates through a twoway valve with a hydraulic accumulator and with a vertical pipe furnished with a piston-like rod. The pipe serves as an exhaust cylinder to receive fluid expelled temporarily from the pressure chamber. According to the first Provisional Specification, the pressure may be applied from above.

摘要： 510,189. Pile-fabric looms. PLATT BROS. & CO., Ltd., and AUSTIN, F. W. Feb. 7, 1938, No. 3726. [Class 142 (ii)] In a loom for weaving Royal Axminster carpets &c., two wefts are inserted by upper and lower needles A. a, Fig. 6, shaped to fit into the forwardly tapering upper and lower parts of the shed, and guided and supported solely by the warps. After passing through the shed, the needles pass between selvage cord containers D, d furnished with large pirns, pivoted fingers &c. f working over grooves d in the container noses causing the weft to return over and under the containers and thus around respective selvage cords. The containers are supported by grooved jaws g on outer and inner pairs of lever arms G, g, which are successively withdrawn from supporting position to allow for the passage of the weft loops. In operation, the lever arms allow the bottom weft to slip off the lower container, but retain the top weft temporarily on the upper container as shown at c', Fig. 3. The tube frame is then inserted between the front and rear parts c , c of the top weft, but behind both parts of the lower weft. The tube frame straightens up, the top weft is allowed to slip off the upper container, the tension pulling this weft tight against the selvage cord e' and moving the rear part c forwards towards the tube' frame. This rises and dwells whilst the part c is beaten up, and then rises further to draw off the correct length of tuft yarn. The lay then retires, the under reed turns up the tufts and the shed changes. The needles may have longitudinal flanges a , a and be each equipped with a permanently threaded eye and a slip eye. In addition, the lower needle has a guide on its underside. The needles may be tubular or have one or more longitudinal bearing ribs.
