AUGUST A. SOHUPINSKY, OF MILWAUKEE, WISCONSIN.

APPARATUS FOR RE'SWEATING AND COLORING TOBACCO.

SPECIFICATIQZJ iorming part of Letters Patent No. 309,569, dated December 23, 1884.

Application filed March 1, 1884.

To 61/ whom itmcty concern Be it known that I, AUGUST A. SonnrINsKY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in an Apparatus for Resweating and Coloring Tobacco; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had-to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide an apparatus in which to reswcat and color drycured leaf-tobacco by moistening and heating it without exposing it to the atmosphere or steam, whereby all liability of burning it is obviated.

My invention is explained by reference to the accompanying drawings, in which Figure l is a perspective view. Fig. 2 is a longitudinal vertical section, and Fig. 3is a detail.

Like parts are represented by the same reference-letters throughout the several views.

A is a sheet-metal tank, in which water is introduced through the tube B by removing the open-topped thimbleshaped screw-cap O, and the same may be heated upon an ordinary stove, or by the application of lamps or in any similar manner. The mouth of the tank A is surrounded by an inward-projecting frame or flange, D, preferably formed of wood; I

From the inner edge of the frame 1) is sus pended the sheetmetal heatingtank E, in which the tobacco to be treated is placed.

Interposed between the frame D and the respective tanks A and E is a rubber or other elastic packing, a and b, which forms a steamtight joint. The tanks A and E are secured to the frame when made of wood, as shown,

by nails or screws (1. The inner packing, a, projects slightly above the top of the tank E, and serves as an elastic bearing for the cover F, whereby the vapor arising from the tobacco in the tank E is prevented from escaping. The inner edge of the frame D is grooved out, forming a shoulder, G, for thereception E, connected together by frame or flange D,

of the cover F. To more securely and tightly close the cover, a fasteningbar, H, is provided, which is held in place at its respective ends by the keepers I I. The cover F and bar H being in place, the bar H is pressed down firmly upon the cover by the wedge-shaped end f and the cam-lever 0, whereby the cover F is pressed firmly upon the projecting edge of the rubber packing a, and an air-tightjoint formed. To provide for the escape of steam in case of too great pressure, the downwardlyextending thimble-shaped screw-cap G has an orifice in its bottom, which orifice is closed by a ball, K, the gravity of which ball is such as ordinarily to cause it to remain upon and close the orifice, but which, by sufficient steam-pressure from within to overcome its gravity, is raised and the orifice thereby opened, permitting the excess of steam to escape into the open air, and which, when such excess of steam has escaped, will, by reason of its gravity, again return to its seat uponthe orifice in the bottom of the stopper, the ball,

when raised from the orifice by the steam, be-

ing kept from getting estray by the walls of the stopper around it and a retaining-guard above it.

In operating my apparatus a small quantity only of water is required, as the best results are attained when the surface of the water is kept below the bottom of the tobacco-tank and the steam permitted to pass beneath as well as around its sides.

To more readily ascertain the height of the water in the tank A, a glass gage, M, of the ordinary construction, is provided, from the lower end of which the water may be drawn off from the tank, when desired, through the hand-valve N.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an apparatus for resweating and coloring tobacco, the combination of external tank, A, frame D, tobacco-receptacle E, elastic packing a and b, and cover F, said packing at having its upper edge projecting above the mouth of the tank E, to serve as a packing to said cover, substantially as set forth.

2. The combination of the tanks A and and packing a and 1), tube B, provided with thimble-shaped screw-cap 0, having an orifice in its bottom automatically closed by a i T ball, K, sight glass or gage M, provided with AUGUST SCHUPIL outlet-valve N, cover F, bar H, keepers I I, Vitnesses:

and cam-lever 0, all substantially as and for 1 O. T. BENEDICT,

the purpose specified. l M. SINNOTT.

In testimony whereof I aflix my signature in presence of two witnesses.
