Application filed May 6, 1916. Serial No. 95,848

To all whom it may concern:

Be it known that I, JOHN F. SULLENBER- GER, a citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented new and useful Improvements in Drying-Machines, of which the following is a specification.

The invention relates to dryingmachines, and more particularly to the class of rotary drying machines for grain or minute substances or materials.

The primary object of the invention is the provision of a machine of this character wherein the drying pans or sections are stacked and readily interchangeable so that of Flg. 1;

any one section or pan will fit upon another and in event that thecapacity of the machine is to be varied for increasing or decreasing the capacity the sections or pans can be added to 'or discarded.

Another object of the invention is the provision of a machine of this character wherein hominy, grits,'meal, grain and various materials can be thoroughly dried therein, the drying sections or pans being heated from coils through which circulates steam, and said sections or pans being incased so as to retain the heat therein for the thorough drying of the materials after the introduction thereof at the. head or top of the machine, which dried material is discharged from the bottom of said machine.

A further object of the invention is the provision of a machine of this character wherein the construction thereof is novel in form and the carriers or feeders for the materials are also novel in formv so that the trend of the material will be in zigzag fashion from the top to the bottom of the machine so that the thorough drying of the Specification of Letters Patent.

Similar reference characters indicate corresponding parts throughout the several I views of the drawings.

' Referring to the drawings in detail, A designates a casing preferably made in section and from sheet metal, the sections of which are detachably fastened together in any suitable manner, and within this case is arranged the machine, which comprises a plurality of superposed, annular rings 10, each being formed with outer peripheral flanges 11 through which are passed at intervals bolts 12, the same being also passed through spacer sleeves 13 arranged between the flanges and the rings adjacent each other, and in this manner the rings are united in series. Each ring 10 has at its lowermost edge an internal annular supporting flange 14 upon which rests a drying pan or section 15 adapted to be riveted or otherwise secured to the flange, and upon the under face of the pan or section 15 are bridge straps 16 which support directly beneath the said pan or section a steam coil 17 it being understood,

of course, that the coils are arranged in series correspondinglyto the series of pans or sections 15 and are connected together so that steam entering one of the coils will circulate through the said coils of the series, the steam being supplied thereto from any suitable source, and the condensation is delivered to the boiler or other steam generator constituting the supply for the live steam to the coil.

Extending centrally through the pans or sections 15 is a vertical shaft 18, the lower end of which is journaled in a boxing or bearing 19 fitted within a supporting spider 20 formed with base feet 21, and this spider is connected to the series of rings through the medium of the base ring 22, as shown,

while at the top of the series of rings is a head 23 formed with a center bearing 24 for the shaft 18, which latter hasfitted on its upper end a beveled gear 25 meshing witlfa pinion 26 fixed to one end vof a drive shaft 27 journal-ed in bearings 28 supported by the'head 23, the shaft 27 being driven in any suitable manner.

. wardly to the periphery of the machine, and

the coils circulating the steam heat the pan or sections 15 for the drying of the material during its zigzag course from the top of the machine to the bottom thereof.

The pans or sections 15 alternately are formed with peripheral and central discharge apertures 31 and 32 respectively, so that the material will be discharged from one pan at the periphery thereof and from' another pan at the center thereof, thereby taking a zigzag course by the action of the series of spirals 29 and 30 thereon from the top of the machine to the bottom thereof so that the material will be thoroughly dried before it is delivered from said machineat the bottom thereof. The case A serves to retain the heat within the machine and the top or head 23 is formed with diametrically opposed openings 88 which permit the escape of moisture from the material and also permit the introduction of the material on to the uppermost pan 1:") within the machine from hoppers or other containers, while the material at the bottom of the machine is discharged therefrom into a chute or other conveyer through the delivery aperture 34: in the lowermost pan or section 15 of the series.

On each spiral 29 and 30 are fixed angularly disposed wings or blades 35 which serve as agitators for the material acted upon by the spirals. Each spiral 29 and 30 is formed with a spider brace 86, which materially strengthens the same and the hub of each spiral '37 is fastened to the shaft 18 through the medium of a set screw 38 which is threaded in the hub.

From the foregoing description, taken in connection 'with the accompanying drawings, the construction and operation of the herein described drying machine w1ll be readily apparent and, therefore, a more exflanges and spacers together, pans support ed upon the internal flanges in the respective rings and having openings centrally and peripherally in alternate relation, means heneath each pan for heating the same, and feeders arranged to travel over the pan for advancing materials to the openings therein.
