Abstract: 25,219. Johnson, J. Y., [Drury, W. H.]. Nov. 29. Combined carding and spinning machines.-Refers to the invention described in Specification No. 29,072, A.D. 1897. The slivers of fibre are carded and spun in one operation. On leaving the ring doffer A<2>, each sliver or strip of fleece is passed through a rapidly-revolving twist tube W, and wound on to a roll or bobbin H<2>, which is driven by friction at such a rate that the material is drawn or stretched between it and the twist tube. Each twist tube contains a pair of indiarubber gripping-pads, and all the tubes are supported and driven by the inner face of a travelling hand or belt L, which passes beneath and above them. The tubes are prevented from moving longitudinally by the rail F. A plain tube may, however, be used, and the strands passed in addition between the upper and lower inner faces of a travelling band, which rubs the strands and condenses them ; or two such bands may be employed, and the tubes dispensed with. In place of employing the usual ring doffers, the strips of fleece may be separated from one another by plates S projecting from the rail F into narrow channels in the doffer. A " wipe roll " may be used for removing the fibre from the doffer, and other rollers may be arranged between the doffer and the twist tubes. When starting the machine &c., the strands of fibre are drawn through the twist tubes and between the rubbing-belts by means of a long steel needle which is pointed like a crochet needle. Special arrangements are made for adjusting the position and speed of the several parts.
