Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed September 14, 1908. Serial No. 453,002.

To all whom it may concern:

Be it known that we, TnoMAs IIowAR'rH and JOHN VARLEY MUsenAvE, subjects of the King of Great Britain, residing at Bradford, in the county of York, in the Kingdom of England, have invented certain new and useful Improvements in Drying Apparatus, for which application has been made in Great Britain, No. 22,325, dated OctoberlO, 1907.

This invention relates to improvements in drying apparatus connected with backwashmg machines for washing wool and the like in which the wool in sliver form or other material to be dried is led around rotating" perforated cylinders through whichheated small radial holes or orifices connecting the interior of the annulus with the exterior, whence the air passes through the perforated cylinders which carry the wool and are rotated on the steam jackets. It will thus be obvious that a very thorough heating of the air is effected as it passes first into a space surrounded by the steam jacket and then through the same before it comes into contact with the wool.

In the accompanying drawings wherein we have illustrated one embodiment of our improvements :Figure l is an elevation of the.

machine in partial section showing enough for the comprehension of the invention."

Fig. 2 a sectional side View of one of the revolving shells and its appurtenances. Fig. 3 represents a Roots blower to be connected up with Figs. 1 and 2.

In these the steam chest at is shown as rigidly mounted upon the plate 6. The steam chest incloses' a space and is provided with a central boss 0 on which is mounted so as to revolve thereonthe shell cl provided with perforations e on its periphery. Inter-- mediate to the shell 01 and'steam chest 0, are

two rings f one of which is provided with suitable packing g. Secured to the shell and revolving on the steam chest is a spur wheel or gear wheel h. The packing g prevents oil used for lubricating the wheel h from entering the annular space between the shell (1 and steam chest a. In the structure herein illus trated the boss 0 is preferably secured to the steam chest by means of a plate 0 integral with it and screws 9'. Between and secured to thg two rings f is a stationary baflle plate k arranged so as to prevent air from passing lout through the apertures or perforations of ithe shell at such parts as are not normally covered by the wool. Pieces of metal a are interposed between the walls of the steam chest 0 and provided with holes a through which air can pass from the space inclosed by the steam chest to the space between the steam chest and the shell. The pieces a do not extend the whole length of the steam chest so that steam can pass from one part to the other. Z Z are the steam supply connections and m m are the air supply connections which are preferably connected up to a Roots blower or other device for supplying air under pressure by means of a pipe 72 which feeds into the gutter 0.

The device is driven from a suitable spur wheel such ,as is indicated by the chain dotted line 10 which gears with the gear wheels h of the upper two shells which in their turn gear with the gear wheels h of the lower set of shells. V

The action of the machine constructed as above set forth, when used for drying wool is as follows :-The wool represented by the dotted line Q as it passes in sliver form from the baclcwashing machine passes over the guide pulley or wheel 1" then down over and around the first shell 01 then up and around the next and so on till it emerges from the apparatus over the guide pulley or wheel 8. While the wool is passing through the drier steam is admitted to all the steam chests a and air forced through all the bosses c after which it is heated and passes by the holes a into the spaces between the steam chests and shells (Z and from thence through the wool about the shells whereby the wool is dried.

, We declare that what we claim is 1. In drying apparatus, a rotatable cylin drical carrier apertured in its perimetral'surface and having an interior chamber cornmunicating with its perime tral apertures,

means for supplying air to the interior chamber of said carrler, and a steam jacket housed Within said carrier and adapted to heat the air supplied thereto.
