IIVIPROVEMENT IN TOBACCO-BRIEFS.

To all whom'it may concern.-

Be it known thatI, SAMUEL T. (Jo'r'rnmnL, of Dayton, in the county of Montgomery, and State of Ohio, have invented a certain. new and useful Tobacco-' Drier; and do hereby declare the following'to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of 'this specification.

My invention relates to a tobaccoahzier, which consists of a series of removable trays or racks, having cloth, wire-gauze, or other perforated bottoms, upon which the tobacco is placed, and these trays are inserted .in the upper end of a suitable drying-chamber, through which a continuous and uniibrmly-distributed current of warm or cold air is forced, by means of a fan, or other blowing-upparatus, and as the air cannot escape from said chamber without passing throughthe perforated trays and their contents, it insures the drying of the'tobacco in the most thorough and espe ditious manner.

[n the accompanying drawings- Figure 1 is a vertical section through a tobaccodrier, embodying my improvements, one of the trays or racks being representedas partially withdrawn from the drying-chamber.

Figure 2 is a horizontal section through the dryingchamber, at the line X-X.

- A represents a frame, which supports a trunk, B, having the form of an inverted pyramid, and this trunk terminates at top in a rectangular drying-chamber, 0, having an opening or door, 1), in one side, for a pur- At the junctionof the trunk B and chamber 0 are secured cleats E, which serve to support a series of removable trays or racks F, whose bottoms, G, are composed of linen, wire gauze, bolting-cloth, or some other equally porous material.

One end of the trays is provided with handles, j; which permit of said trays being readily withdrawn from the drying-chamber when desired.

Inserted in the lower end of the trunk B is a pipe, H, which communicates with a fan, or other blowingapparatus, I, and the other end of said pipe H has secured to it an air-chamber, J, from which project,- in various directions, a number of goose-necks, K, whose nozzles project downward.

At the open end, D, of the chamber 0, are stops,

L, so situated as to prevent the second tray being displaced when the first or lower tray is withdrawn.

My ch'ying-apparatus'is operated in the following manner: v

To dry fine-cut chewing-tobacco, two trays are ordinarily used, ,and they are inserted empty in their proper places in the chamber 0, the lower one resting upon the cleats E, and the second tray immediately upon thmfirst.

,gcntle vibration of the bottoms of the trays,

The fan 'or blower is started with a full blast, and the tobacco is then spread quickly and evenly upon. the upper tray. The lowest tray is then withdrawn at the opening 1), and the upper tray containing the tobacco falls down upon the cleats E. The empty tray is inserted above, and tobacco spread upon it as upon the first one. The first tray tilled, first exposed to the intense blast of rarefied air, will be the first dried. As soon as its contents are dry, it is withdrawn, emptied, placed in,the chamber 0, on the remaining tray, which has now fallen upon the cleats E, and is again iilled with tobacco. If three or more trays are employed, the process is the same, the tobacco being spread upon the upper tray, while the blast is in operation, and the lower tray withdrawn as soon as its contents'aredry.

The reboundingair in the trunk B produce; quick, nd this, with the liiting power of the large volume of forced through the trays by the fan, enables the tobacco to be easily spread even, without packing into lumps, and frees lumps made in cutting.

The provision of the series of goose-necks prevents the blast taking a direct central passage through the trays, and they compel the air to be thoroughly distributed, and to act on all portions of the trays alike, as indicated by the blue arrows in fig. 1.

This distribution is effected by turning the nozzles of the goose-necks down, by which means the air, as it issues from them, comes in contact with the inclined sides and bottom of the trunk, from which it is deflected, and broken up into innumerable small and uniform currents; The air which is employed may be cool, warm, or hot, depending upon the state ofthe weather, and the condition of the articles to be dried, as this apparatus may be used for various other purposes besides drying tobacco.

' It has been found by practice that tobacco can be thoroughly and uniformly dried in my apparatus in from five to ten minutes, and as there are no small lumps to be reduced after drying, the amount ofshorts is materially reduced.

When it is desired to use the apparatus for laundrypurposes, or for drying leaf-tobacco the. trays may be omitted, and the trunk; B and chamber 0 be inverted, so as to admit air from the top.

The walls of the chamber may be extended, and the clothes or tobacco may be hung upon cords, pins, or slats.

I claim herein as new, and of my invention-- 1. A rh-ying-chamber, consisting of the irame 0, having cleats E, and an open end D, provided with stops L, in combination with the nest or series of gravitating-trays F, for the purpose of allowing the withdrawal of said trays, in the manner described for the purpose specified.

2. "the combination, with the upwardly-flaring trunk porous-bottomed trays F G, blast-pipe H, and gooseneeks K, for the object stated.

B, and flying-chamber 0, arranged as described, of the series of l'n'nvneh-pipes or goose-necks K K, having downwardly-proieating nozzles, for the purpose of distributing; the blast of air forced through said dryingchu-inher, as set forth.

3. The arrangement, substantially as described, of the flaring trunk B, drying-chamber O,removab1% and hand.

In testimony of which invention, I hereunto set my GEO. H. 11mm, JAMES H. LAYMAN.
