IPC: F26B13/16
Abstract: 17,108. Layland, W. E., and Whitehead, J. H. July 26. Drying wool.-In the apparatus shown in Fig. 2, in which slivers of wool pass in a continuous band over a series of perforated cylinders i, stationary plates s prevent air from escaping except through the wool. The cylinders are contained in one of two compartments into which a chamber is divided, the other containing heating- pipes t. One set of ends of the cylinders opens into the latter compartment, and air is driven over the heating-pipes and through the cylinders by means of a fan w working in a passage v connecting the two compartments, as shown. A regulated inlet opening y in the passage v and a regulated outlet opening in the top of the chamber are provided ; their valves may be similarly actuated from any part of the machine. At one end the cylinders are supported on races m carried by the partitions g by means of rings carrying intermeshing wheels l. At the other end, they are carried on conical pieces n rotating on pins o carried by supports p cast with the rings m. Feed, guide, and delivery rollers are provided. In a modification, a fan w is placed at the open end of each cylinder, which may contain a steam coil, either instead of or in addition to the pipes t. By placing the fan near the heating-pipes, a fall of air pressure and consequent condensation of moisture takes place in the cylinder chamber, the condensed moisture being withdrawn at the bottom.
