    • 523,001. Drawing fibres. PLATT BROS. & CO., Ltd., HUGHES, J., and WATSON, W. H. Dec. 20, 1938, No. 36991. [Class 120 (ii)] The endless band of a highdraft drawing head employed in spinning and like frames is guided and tensioned by a resilient metal bracket which is clipped on and secured to the nose bar around which the band passes, has a gap for the passage of the band, the edges of the gap restricting lateral movement of the band, and has the free end of the bracket formed with a roll or curl or provided with a pin which presses against the band and tensions it. As shown the bracket 22 has a slideway 22a which clips over the nose bar 19 and is secured thereto by a set screw 23 and the spaced arms 24 depending from the part 23a of the bracket are turned up and provided with a cylindrical pin 25 bearing against the band 21; the band passes between and is guided by the inner edges of the arms 24. The pin 28 has slits in its ends which engage notched parts 24b of the arms 24. The band passes over the part 23a of the bracket and so wear of the nose bar is eliminated. In a modification for use with a nose bar having a flat rear end, the slideway 22a is formed by a part turned down at right angles to the top of the bracket and a part turned up at the edge of a slot through which the band passes, the band being guided laterally by parts struck up at the ends of the slot and being tensioned by a roll or curl formed at the end of the bracket opposite the slideway.

    • 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.

    • 483,781. Insecticides ; holders for disinfectants. HUGHES, J. May 14, 1937, No. 13607. [Class 81 (i)] [Also in Group I] A siphonic or like cistern is provided, to prevent mosquitos breeding, with one or more containers 5, each having two or more holes or slots 7, 8, 9, 10 at different levels to which the water in the cistern may rise or sink, each container being charged with an absorbent medium such as cotton waste impregnated with mineral sump or like oil whereby, as the water level rises in the cistern, water enters the container at the lower holes, and oil is floated up on the rising water to escape at the upper holes and form a film on the surface of the water, the operation continuing until the medium is denuded of oil. The container may be of a cylindrical or other shape, with a detachable top 6, and the slots 7, 8 and 9, 10 have their lower edges 11, 12 bent inwards and outwards respectively to aid the flow of water and oil. The cotton waste is enclosed in a gauze or like bag. The container may be placed on the siphon of the cistern or be incorporated in the wall or other part during manufacture. The mineral sump oil contains particles of iron and light oil residues.
