TOBACCO-RESWEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 457,464, dated August 11, 1891.

Application filed April 9 1891. Serial No. 388,318- (No model.)

To all whom it may concern:

Be it known that I, BRUNO MARTIN, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Tobacco-Resweating Devices; and I do declare the following tobeafull, 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 the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in devices for resweating tobacco, and is especially adapted and designed as an improvement to inventions described in Letters Patent issued to me May 22, 1883, No. 278,029, and LettersPatent issued July 15, 1884, No. 302,011; and it consists in the construction of the devices so as to use the system of ventilation hereinafter described.

Figure 1 is a side and end perspective View of the resweating device. Fig. 2 is a front sectional view showing the inside of the sweat-box and its internal construction.

B is the sweat-box.

C is the sweat-chamber, where the tobacco is placed for sweating.

The box B is made with a cavity or airspace 6 6 in its walls, all opening into an air-space 6 in the top. From this air-space at the top I have one or more vents 5 5, passing through the outer covering of the box, and at or near the bottom of the box I bore one or more holes 4 4 through the outer walls into the air-spaces 6 6, thus affording a means for the circulation of air in the air-spaces 6 6. The object of this will be apparent when we consider the use made of the device in resweating tobacco.

, In my patents previously mentionedlhave described means for resweating the tobacco placed in the sweat-chamber 0, whereby the steam is generated and directed into the chamber 0. In the resweating process that follows the nicotine from the tobacco is taken the steam, and if the walls are made solid it will come out upon the outside, makingit damp,nasty,andslimy. Byformingair-spaces -6 6 within the walls, provided with the fines at the bottom 4 4 and the vents at the top 5 5, whereby when the dampness and nicotine penetrate through the inner wall they will be taken up by the air circulating through the air-spaces. The heat from the sweat-chamber will assist the circulation in the airspaces. The circulation may also be accelerated by attaching the pipe 7 so that its lower end will come within the radiation of the burner under the device and having at its upper end a cross-pipe 8, provided with tubes 8' 8', entering into the air-spaces 6 6 and conveying the heat from the radiatorbelow into the air-spaces,thusmaterially aiding in drying out the walls of the air-spaces. When the resweating process is finished or when for any purpose it is necessary to open the box into the sweat-chamber C, the s eam loaded with nicotine will rush out into the room, and being so noxious it will be almost impossible to remain long in the room. In my device I remove the steam from the sweat chamber at pleasure, so that no steam need enter the room. I arrange a pipe 3, connected to a stove-pipe or chimney at one end and to a tube 2 in the upper part of the box entering into the sweat-chamber C. In the lower part of the box I place one or moretubes 1 1, passing through the walls of the box into the lower part of the sweat-chamber, each tube being provided with a cutoff or stop valve, which I have shown in the tube 2 as a slide 2. An ordinary cap or cork may be placed over the mouth of the tubes 1 1. By opening up the valves it is obvious that the steam will pass up the pipe 3 and cold air will rush into the chamber 0 through the tubes 1 1, and in a few moments the chamber 0 will be free from steam and noxious odor.

I do not wish to confine myself to the mechanical construction shown, and any change may be made as comes within ordinary mechanical skill without departing from the principle of my invention.

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

1. A tobacco resweater consisting of a sweat-cha1nber having double walls an "1 ceiling, said walls and ceiling having air-spaces connected and provided with one or more times at or near the bottom through the walls from the outsideand one or more vents in the top, whereby the air in the air-space is kept in circulation, and means for heating the sweat-chambeiysubstantially as described.

2. A tobacco -resweatcr consisting of a sweat-chamber and means for heating the same, said sweat-chamber having double walls and ceiling and having a connected air-space between its walls and ceiling, provided with cold-air fiues through the outer walls and hotair vents through the ceiling, said air-space being connected by means of a pipe 7 and 8 to the radiating-surface of the heater below,

whereby hot air'is conveyed into the airspace, s-ubstantially as described, as and for the purpose set forth.

In a tobacco-1'esweatei' consisting of a box having double walls and ceiling, with ventilating and circulating air-space between the walls and ceiling connected, and means for conveying warm air from the radiator into the air-spaces, said sweat-chamber being provided with cold -air openings through the double walls near the bottom and a warm-air outlet connected to a chimney or pipe at the top, means for heating the sweat-chamber, and means for opening and closing the outlet and inlet air-passages, whereby the vapor, steam, and nicotine may be removed, substantially as described.

In testimony whereof I affix mysignat'ure in presence of two witnesses.
