Abstract

167,837. Hollis, T., and Woodmansey, A. May 15, 1920. Openers &c. ; carding-engines.-Wool and other fibres to which oily lubricants are applied during their preparation for spinning are opened, carded, &c. in a bath of oil or oily emulsion. The oil &c. is contained in tanks G and H and is also sprayed on to the material at the feed and delivery ends through pipes D<3>, D<4>, D<5>, and V<1>. The material is fed in on an apron A and is carried by an apron B, under pressing-rollers C, C<1>, C<2> to carrying or drafting rollers E - - E<5>. It is then passed to a series of toothed rollers I, I<1>, I<2> co-operating with small toothed rollers M, N, O. These rollers work in compartments in a perforated inner shell G<a> arranged to break up any currents set up in the oil &c. Two further rollers J, K co-operating with a series of small toothed rollers P, and a series of plain rollers Q respectively are arranged above the surface of the bath. The roller K acts as a doffer and delivers the material to a pair of rollers R, R' and an apron S whence it is passed by an apron T to squeezing rollers U, U<1> and the delivery apron A<1>. The rollers R, R<1>, squeezing rollers, and delivery apron are arranged above the tank H which is provided with a perforated grid Ha to catch detached fibres. The rollers I, I<1>, I<2> are supported in a frame Z pivoted to the axis W of the roller J. The small rollers above the axes of these rollers are carried by brackets secured to arches mounted on a frame Y, which is also pivoted on the axis W and supported by the axes of the larger rollers. A second frame Y<1>, which can be secured to the frame Y, carries arches on which are mounted brackets to support the small rollers below the axes of the rollers I, I<1>, I<2>. The frame Z normally rests on ribs secured to sides of the tanks, but can be raised to lift all the rollers out of the liquid. The main drive is on the shaft 1 of the lower squeezing- roller, and the other parts are driven from this shaft by suitable spur and chain gearing. The liquid in the tanks may be heated by steam pipes. The spray pipe V<1> may supply clean lubricating liquid to the material. The number and arrangement of the working-rollers may be varied to suit the material under treatment. The material may be passed through a series of graded machines and be delivered as a web or lap, or as a sliver to be wound in a ball or coiled in a can. Endless travelling aprons, or series of bars, which may be provided with teeth, can be substituted for the rollers.
