DRYlNG-MACHINE.

v5.1.3111GIFIGATION forming part of Letters latent No. 543,578, dated July 30, 1895.

Application-tiled November 25| 1892. Serial No. 453,014. (No model.)

a drying-machine in Which the material will be subjected to the action of the drying medlum in a more thorough manner than heretofore.

-The invention consists in the peculiar construction of the drying-,cylinders and the means for introducing dry air or other oxidizing medium to the interior of the same.

The invention further consists in the combination of a number of peculiarly-constructed drying-cylinders with suitable standards inclosed within a chamber and having airsupply pipes, as will hereinafter be more fully described, and pointed out in the claim.

Figure 1 represents an elevation of one form of the improved drying-machine, the wall of the inclosing-chamber being shown in section. Fig. 2 represents an enlarged crosssectional View of one of the drying-cylinders.

Fig. 3 representsalongitudinal sectional view of the same to more clearly indicate its construction and the connection with the airsupply.

Similar numbers of reference designate corresponding parts throughout.

In the drawings, 5 5 indicate cylinders or cages formed of the ends 6 6 having circumferential gears 7 and tho bearing-collars 8. The ends 6 6 are connectedby the bars or rods 9 9, the bearing-collars 8 being journaled on the., sleeves 10, which are rigidly secured in the hubs 11 of the brackets 12. On the internal ends of the sleeves 10 are shoulders 13, which bear against the inner surfaces of the ends 6 6, and inwardly beyond these shoulders are the spiders 14, which may have any number of branch connections 15, the corresponding branches at the opposite ends of the cylinder being connected by the pipes'or tubes 16, the ends of which are curved to t into the branches of the spiders, While the main length ot' the tubes extends parallel to and slightly within the bars or rods 9 9, the outer surface of these tubes or pipes 16 being furnished with the longitudinal slots 17.

Dry and heated air or other oxidizing medium is admitted to the sleeves 10 and thence to the tubes 16 by means of the supply-mains 18, having branches 19, which connect with the outer ends of the sleeves 10, the mains 1S being connected with an air-blast ot' any usual and ordinary form.

When arranged in Vertical series, as shown in Fig; 1 of the drawings, the brackets 12 eX- tend alternately from opposite sides of the standards 2O and are located with reference to the diameter of the cylinder-heads 6, so that the gear-teeth 7 of each pair of headsin termesli with the gear-teeth of the heads next above and below, so that, by driving one `cylinder in each series, rotation will be imparted to the remaining cylinders. In this construction the gears 2l are journaled in bearings mounted on the cross-bars 22 and intermesh with the gears on a cylinder of each of the vertical series, these gears 21 being driven by the gears 23 mounted on the drive-shaft 24, the ends ot" which are suitably journaled, this drive-shaft being driven in any usual manner.

The series of cylinders are contained Within the chamber 25, and the cloth or other material to be operated on passes into the same through a suitable opening. It then passes partially around each ofthe cylinders in turn, being subjected to the action of heated air which is forced through the slots in the tubes 16, and by this means is thoroughly dried without being brought into contact with the heated metal of the tubes.

It is obvious that any number of the cylindrical cages may be used in each series. The cylinders may be of any diameter and length, and they may` be journaled in horizontal frames, if desired, modifications being made in the size and shape of the inclosing-chamber, or this chamber may be dispensed with when it is not necessary to coniine the heated air escaping from the cylinders.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a drying or oxidizing machine, the combination with an inclosing chamber having an inlet and an outlet through which the fabric to be treated may be passed,of the standards -20-20 mounted within the chamber and furnished with the brackets 12--12 extending alternately in opposite directions, the crossbars 22 connecting the standardsinpairs, the sleeves 1.0--10 mounted in the brackets 12-12 and furnished with the spiders 14 having branched outlets 15, the slotted-tubes 16 connecting the corresponding branches of the spiders, cylindrical cages formed by the heads 6-6 connected by the rods 9-9 and having In witness whereof I have hereunto set my hand.
