IMPROVEMENT IN TOB-ACCO-SPRAVING APPARATUS.

Specification forming part of Letters Patent No. 187,187, dated February 6, 1877,; application filed January 8, 1877.

' To whom it may concern 1876, No. 172,666, (reissue No. 7,195), for a method of atomizing or spraying liquids, for the purpose of moistening tobacco. In said patent the apparatus then proposed to be used is indicated, but actual use disclosed'and experience showed certain imperfections or defects in the operation, which it is the object of our present invention to avoid and remedy.

rIhe general object of the apparatus herein shown will be understood by reference to said patent. It is thereforeonly necessary here to give a full, clear, and exact description of the manner in which the said 'machine is constructed and operated. The main part of the machine consists of a cylinder, A, of suitable dimension, held and supported in. an inclined position, as shown in Figures 1 and 2, by means rllhe cylinder, being intended to be revolved, is provided with iianged hoops or rings G C', which rest upon the tread or periphery of friction-rollers r, which freely revolve in or on the standards' B B. Revolution is imparted to the cylinder by means ofthe pinion D, which meshes in with a gear-wheel or hoop, E, fast on the. cylinder. The said toothed hoop may be formed upon the rear end of the iiange of the hoop C, as shown in the drawings. Internally the cylinder is provided with several ianges, G G, preferably twisted or spiral, the object of which is to properly agitate, dress, and loosen the tobacco, thus rendering it more susceptible to the action of the sprayer as it is conveyed from the upper to the lower or delivering end of the cylinder. The upper or receiving end of the cylinder is slotted in that portion which is in rear of or above the flanged hoop C. Over this end of the cylinder lits-to b e capable of sliding upon it-a cap, H, composed, first, of a closely-fitting cylinder similarly and correspondingly slotted with the main cylinder A, but having the slots or-openings covered with wire-gauze, I, of suitable mesh 5 secondly, of a head-piece, K, having an opening in the center through which the` vdeiiect the tobacco and to pass it upon the flanges of the cylinder. By this arrangement, and by simply turning the outer cylinder, the openings in the upper cylinder may be closed or opened, or the openings may be regulated at will, to control and regulate the quantity of shorts, or iine dust, which is to be separated from the fine-cut tobacco while passing through the cylinder.

At the lower or discharge end of the cylinder is held, at the proper height upon a standard, L, a vessel or can, M, which contains the glycerine or other liquid material desired to be embodied with the tobacco, for the purpose of sweetening, moistening, or avor'in g the same.

Into the lower end of the can M is screwed or otherwise secured a combined faucet steam or air atomizer, N, of a peculiar construction. (Shown on an enlarged scale in Fig. 3, in two views, being a longitudinal section and a front end view of the atomizer with the nozzle removed.) This combined faucet and atomizer is composed of four parts, viz:

First, the faucet proper, c, having twoscrewthreaded ends, one of which fitsinto the can, while the other fits into the body of the atomizer. It is centrally bored through, so as to form a channel, and a (one or two Way) cock is applied to establish or intercept the iiow of liquid through it. A small chamber, b, is also formed in the forward end around the channel or bore.

Second, the body of the atomizer c. is pierced throughout its length by small channels, which communicate with the chamber b,

in the faucet c. It is also centrally perforated to a certain depth, to communicate with another perforation or channel at right angles to it.

Third, the nozzle-piece d, which forms a chamber around the forward end of the body of the atomizer c, isscrewed onto it, so that This ' in front of the part a, and is, by means of the several small channels in the body of the atomizer, permitted to trickle through into the .recess or chamber formed in the nozzlepiece d, where it comes in contact with the steam or air which is admitted through the pipe e, between the rst and second recesses or chambers in center of the cylinder, and is forced into the conical-shaped nozzle, from the mouth of` which it is sprayed in a line mist and in requisite quantity upon the tobacco.

The vessel or can containing the liquid is supported on a stand, and to this stand is attached a hollow steam-pan, to which are connected two steam-pipes at the bottom, onel to admit the steam and the other to permit the condensed water to pass away. The object of this steam-pan is to heat or warm the liquid material used.

The apparatus we have described, it will be seen, accomplishes one great end, and that is, the body of the liquid does not come in contact with the steam or air except in such reduced quantity and at such a point as will insure its being constantly and perfectly taken up by and diffused through the gaseous or aeriform fluid, and therefore not capable of condensation or being conveyed in quantities to unduly humectate the tobacco to be operated upon.

f Having thus described our invention, what we claim, 'and desire to secure by Letters Patent, is

1. The combination, with an atomizing apparatus, of a cylinder revolving upon an inclined axis, through which the tobacco. to be treated is passed, substantially as shown and described.

2. The construction of the revolving cylinder, as shown and described-that is to say, provided with internal anges and a Acentral deiector for the purpose of properly agitating the tobacco while being fed through the cylinder.

3..'lhe construction of the cylinder with a feed-head, having adjustable openings to regulate the separation of shorts from fine-cut tobacco, substantially as set forth.

4. The apparatus for supplying liquid to be atomized in quantities and ata point or points relatively to the air or steam jet, so that the same may be taken up and diifused in requisite quantities, substantially as herein shown and described.

5. The combination in one apparatus of the following elements: first, the faucet to regu-`V late the quantity of liquid delivered to the atomizer; second, the atomizer provided with channels to convey the liquid supplied by the faucet; and, third, a chamber to hold the liquid to be atomized; the whole being constructed and arranged for joint operation, substantially as shown and described.

In testimony whereof we have hereunto signed our names this 19th day of December, A. D. 1876.
