To 11N who/r1, it mfr/1] con/corre.-

Be it known that l, CARL l?. llnncslc, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Grai11Drying Apparatus, of which the following is a specilication.

This invention relates to improvements in a grain-drying apparatus, and has for its object to provide a device of this class that is simple in construction, is easily operated, and presents a large area of heating drying surface within a compact space.

This apparatus is more especially intended l to be of the portable type, so that the same can be convenien.tly moved from place to place as the work may require. It is, however, obvious that it may be constructed of large proportions in a stationaryr position where large quantities of different kinds of grain are handled. in bulli.

ln the drawings, Figure l is an elevation of an apparatus embodying the improved. features. Fig. 2 is a loiigitudinal section on line 2, Fig. l, looking in the direction indi.- cated by the arrow; and. Fig. 3 is a transverse section on line 3, Fig. l.

A represents a hollow cylinder which is rotatably mounted on a supporting frame or base B. The companion sheaves Ll and 5 are rigidly mounted. on the cylinder and are located adjacent to the respective ends thereof. But two mounting-sheaves are shown in illustrating a practical workin g device. It will be understood, however,that this number may be increased in accordance with the length, di.- ameter, and weight of the cylinder to be supported.

A number of friction-rollers 6 are provided with suitable journal-bearings in the :frame and are relatively located in engagement with the sheaves et and 5, as best shown in Figs. 2 and 3, in supporting the cylinder A in its revoluble position. A driving gearwheel 7 is also mounted on the cylinder A and illustrates one means for receiving motion from the motive power to be utilized.

A hollow drier-body C .is located. inside of the cylinder A and extends longitudinally therewith, as best shown in Fig. 2. The body C is triangular in cross-section and presents inclined surfaces 8 and 9, providing a large area of heatingssurface within a conipact space. A series olf distributing buckets or carriers l0 are rigidly, Figs. 2 and 3, to the .inner cn'cun'rl'ere-nt1al surface ofthe cylinl der A and serves the purpose of carrying the grain upward and discharging or dropping the same onto the inclined drying-surface presented by the drier-body (l.

l The cylinder A is provided in the discharge end with an o liening 1]., the diameter of which is .reduced by an inturned `flange l2, which checks too rapid an outllow of the grain. '.l his end of the cylinder is loosely covered by a cap 13, supported in a station.- ary position loy one or more brackets ld. This cap is provided with a spout l5, through which the grain is discharged in the operation of drying. The intake end oi the cylinder is provided with a receiving-hopper 116 opening therein.

A heat-generating furnace l7 has a heatconducting pipe 18 connecting therewith., which leads through and heats the dryingsurface of the triangular body C and then ends in a suitable escape-flue. Another :form of heating apparatus from that shown niay be used. when convenient.

The cylinder A is set on an incline, so that the grain being treated will gradually gravitate to the point of discharge with each revolution. The degree of inclination and. the speed. of rotation. may be varied in accord ance with the condition of the grain and the length of time it must be retained in the cylinder in completiiig the process of-drying.

In operation the grain to be dried is gradually 'fed through the hopper end of the cylinder and is picked up by the series of buckets and carried upward with. each revolution and distributed over the inclined surfaces of the drier-body, from which the grain gravitates back to the lower part of the cylinder to be again carried up, and so on in continuous order of circulation until. it gradually escapes from the discharge end in a dried condition.

Having thus described my invention, what l claim ish l.. In a grain-drying apparatus, a hollow cylinder rotatably mounted in an inclined position, a stationary drier-body triangular in cross-section and extending longitiulinally through said cylinder, and a heating-pipe extending through said drier body and project- `:ing from both ends of said cylinder.

2. In a grain-drying apparatus, a revolu ble cylinder, a number of carrier-buckets disposed at intervals around the inner circumferential surface of said cylinder and set at an. oblique angle with. reference to the axis there- Stealn heat may be used of, a hollow stationary drier-body triangular l In testimony whereof have signed my in cross-section and inclosed Within said oyll name to this specification in the presence of inder, a heating-pipe extending longituditwo subscribing Witnesses.
