ORIGEN M. MILLER, OF.AMSTERCDAM, NEW YORK; COEA HERRICK MILLER ADMIN- ISTRATRIX OF SAID ORIGENM. MILLER, DECEASED.

DRYING-MACHINE.

To all whom it may concern:

Be it known that I, ORIGEN M. MILLER, a citizen of the United States, residin at Amsterdam, county of Montgomery, tate of New York, have invented certain new and useful Improvements in DryingMachines, of which the following is a specification.

This invention relates to drying machines and has for its object the provision-of a machine of this character in which the drying operation is performed with the aid of a current of air which is caused to circulate through the material to be dried.

In carryin out my invention I provide a series of poo ets for receiving the material to be dried and force air through the pockets. The pockets are preferably arranged on the periphery of 'a-drum and maycomprise receptacles or baskets which fit into openings to form closed pockets. A current of air is forced through the pockets preferably by means of a an revolving within the drum. Openings are provided from the fan through the, pockets and to this end the top and bottom of the pockets may be perforated. The drum containing the pockets may be caused to rotate alternately in opposite directions at a speed which is lower than that of the fan, so that the material to be dried will not roll up and become so compact that the air will not readily circulate through it.

Otherobjects and purposes of my invention will appear in the course of the following specification, in which I have shown my invention embodied in concrete mechanism for purposes of illustration.

In the drawings, Figure 1 represents a side view of my machine with the casing partly broken away to show the interior arrangement; Fig. 2 is a similar end view; and Fig. 3 is a perspective view of one of the receptacles.

Referring now to the drawings for a full understanding of my invention, 10 represents a closed box or casing in which the drying operation is performed. This may be built of wood having a sheet metal lining. The interior of the casing is made accessible by having one side 11 on ninges so as to constitute a door. Within this casing is a rotatable drum or carrier 12. Around the eriphery of the drum are pockets 13 which communicate with the in- Speciflcation of Letters Patent. Patented J an. 13, 1914,

terior of the drum through perforations. In the speclfic arrangement shown I provide two circular end members 14 between.

which are secured radial partitions 15 forming the sides of the pockets. The bottom of the pockets is formed-by a drum 16 of perforated metal or wire screen. At each end of the drum is an annular casting 17 arranged concentrically with the drum. Tie rods 18 pass from one casting to the other through the drum to secure all parts securely in place. These castings 17 are flanged so as to form flat rings 19 which act as drlving supports for the drum. The rings are supported on wheels 20, there being two wheels for each ring. The four wheels 20 are arranged as shown on two shafts each having bearings on the cross bars 21. These four wheels support the drum and at the same time rotate it by frictional e'ngagement with the rings 19. The four shafts are geared together in pairs by sprocket chains 22, while two of the shafts each have an additional sprocket wheel 23 which is geared to the oountershaft 24 by a sprocket chain 25.

In' the operation of my machine I find it desirable to periodically reverse the rotation of the drum and to this end I rovide for the reversing of the oountershaft 24. This may be done in any well-known manner, as, for instance, by means of an automatic belt shifter 26, Any well-known form of belt shifter will suit my purpose, but in the present case I have shown the oountershaft 24: as being provided with two loose pulleys 27 having a tight pulley 28 between them. Open and crossed

belts

29 and 30, respectively, pass to the driving shaft 17. The belts are shifted in a well-known manner by the worm gearing 31 operating the shifting rod 32. It is obvious from this construction that as the oountershaft 24 is rotated first in one direction and then in the other the drum will be similarly rotated and reversed.

In order to provide a cover for the pockets and likewise to provide a receptacle for the ,tends through the casing and is provided with a driving pulley 39 which in turn is driven by a belt 40 from the driving shaft 17. The fan is belted so as to be driven at a higher speed than that of the drum and is of course rotated continuously in the same direction. The interior of the casing is heated by means of steam coils 41 in any desired manner. Fresh air. is drawn in by the blower through the intake pipe 42- and is discharged through the pipe 43.

The operation of my device is as follows: The material to be dried is placed in the receptacles 34 which are locked in the pockets of the drum. When all, or the desired number of receptacles are filled the door 11 is closed and the machine is started. The drum revolves a few revolutions in one direction'and then reversing makes a like number of revolutions in the opposite direction. This prevents the material from being rolled up and compacted, which would tend to prevent the proper circulation of air through the material. The rotation of the fan within the drum forces air through the screen 16, thence through the material and out through the screen 34. By this arrangement a stream of fresh air, which preferably is heated, is forced through the material and causes it to dry quickly. By placing the fan in close relation with the material to be dried, a more eflicient action of the air is produced. By providing a plurality of pockets it is possible to keep the materials in groups separate from each other, as desired, so that the materials will not have to be assorted after they are re moved from the drier.

While I have shown my invention as embodied in concrete structure and as operating in a definite manner in accordance with the patent statutes, it should be understood that I do not limit my invention to the particular construction or arrangement of parts herein shown and described except is so far as it is limited by the scope of the claims annexed hereto.

What I claim as new and desire to secure by Letters Patent of the United States, is

1. A clothes drying machine comprising a rotary drum, a fan within said drum, and a plurality of pockets arranged around the periphery of said drum each having a perforated top and bottom so that the air from the fan is forced through the pockets radially of the drum.

2. A clothes drying machine comprising a rotary drum, a fan within said drum, a perforated Wall surrounding said fan, and a plurality of receptacles having perforated bottoms arranged around the periphery of the drum so that said wall forms a cover for the receptacles, the air from said fan being forced through the receptacles radially of the drum.

3. A clothes drying machine comprising a drum provided with means for rotating the same alternately in opposite directions, a fan within said drum, and a plurality of pockets arranged around the periphery of the drum each having a perforated top and bottom so that the air from the fan is forced through the pockets radially of the drum.

4. A clothes drying machine comprising a rotary drum, a fan within said drum, a perforated wall surrounding said fan, a plurality of partitions extending between the walls of the drum outward from said wall to form pockets, and a plurality of receptacles having perforated bottoms arranged to enter said pockets so that the air from the fan will be forced through the receptacles ra dially of the drum.

5. A clothes drying machine comprising a rotary drum, a fan within said drum, a plurality of radial partitions extending between the walls of said drum and outwardly from the fan, and a plurality of detachable receptacles secured between said partitions to form pockets, said pockets having perforated tops and bottoms through which the air from the fan will be forced radially of the drum.

6. A clothes drying machine comprising a radial drum, a fan within said drum, a plurality of radial partitions extending between the walls of said drum and outwardly from the fan, a plurality of detachable receptacles secured between said partitions to form pockets, said pockets having perforated tops and bottoms through which the air from the fan will be forced radially of the drum, and means for rotating the drum alternately in opposite directions.

In witness whereof, I have hereunto set my hand this 30 day of August, 1910.
