NITED STATES rica ATENT srEcIFIcArrIoN forming part of Letters laitht No. 610,444, dated se tember 6, 1898. Application filed October 21, 1897. Serial No. 655,990. .(lI model.) Patented in Brazil April 10, 1897, No. 2,228.

we have obtained Letters Patentin Brazil,

No. 2,228, dated April 10, 1897,) of which the following is a full, clear, and exact description.

Our invention relates to driers for all kinds of articles, such as fruit, meat, clothes, fab' rics, minerals, chemicals, &c.

The object of the invention is to secure a quick and thorough drying action combined with extreme economy. These results we obtain by the construction hereinafter described and claimed, in which hot and coldair are employed simultaneously in the particular manner hereinafter set forth.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of our im proved drier on the line 1 1 of Fig. 4:. Fig. 2 is a sectional elevation on the line 2 2 of Fig. 4.. Fig. 3 is a sectional plan on line 3 3 of Fig. 1, and Fig. 4 is alike view on line 4 4 I of Fig. 1.

The drier, as shown, consists of a square masonry structure having outerwalls A, within which is inclosed an inner structure having walls B. On these inner walls is supported by means of blocks Ca receptacle D to receive the heated air or gases from a furnace E, said air being conveyed through a pipe F, having a damper f, so that the draft may be regulated. The walls A and B are connected at the top of the inner walls by a floor G, separating the lower chamber II from the upper or drying chamber I. Access to the dryingchamber may be had by the stairs J, leading to a door which is normally closed, as are also the windows K in said upper chamber. The air is free to circulate in the chamber H around the walls B, and whenever it is desired to admit air into the upper chamber I this is done by opening windows L in the walls B, so that the air can pass into the inner chamber H, which communicates with the drying-chamher I. Theproducts of combustion from the furnace E after passing up the pipe F into the receptacle D are conveyed downward ,through pipes M in the chamber H. Said ipipes M are connected v at the bottom by a horizontal pipe N, which communicates with ,the discharge pip'e O,leading through the dry- .ing-chamb'er I and'thro'ugh the roof P. (See Fig. 2.) The lower portion of the dischargepipe is within the chamberII'.

To secure a better circulation of air in the drying-chamber I, it may be provided with a horizontal apertured partition or floor Q, and above said floor may be arranged supports R in the nature of bars or hooks or other devices, according to the character of the articles to be dried. The moisture expelled from the articles escapes through the ventilator or chimney S. The roof P, as well as the inside of the drier, is to be lined with sheet metal. We prefer to locate a thermometer (not shown) in the chamber I at the height where the articles to be dried are suspended, so that the temperature may be properly observed and then regulated accordingly by means of the damper Air enters into the chamber II from one side through an opening in the outer wall A. (See Fig. 2.)

It will be understood that in the reservoir D the lighter portions of the heated gases ascend to the top and remain there, while the heavier portions, particularly the smokethat is, the unconsumed fuel-descend through the pipes M. Most of the heat of these heavier combustion products is given 01f during their passagethrough said pipes M and through the discharge-pipe O, the path 'of said gases being lengthened in the manner described for this very purpose. The dryingchamber is thus heated uniformly, both from the receptacle D and from the pipes M and 0. Should the temperature rise to a degree liable to injuriously affect the substances under treatment, the windows L may be opened, so as to let in cool air and reduce the temperature of the drying-chamber accordingly.

Although our drier is applicable to the treatment of various substances, as hereinbefore mentioned, we believe it willbe of particular value in the preparation of hung beef.

We do not limit ourselves to the exact construction shown. Modifications, if within the scope of the appended claims, will obviously involve no departure from our invention.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A drier having spaced inner and outer walls, the outer wall being continued upwardly beyond the inner Wall, and the inner Wall being apertured to afford a communication from the central space of the drier to the space between the two walls, spaced supports such as blocks located on top of the inner wall, a receptacle supported on said blocks so as to leave air-passages between the receptacle and the inner wall, a heater surrounded by the inner wall, a pipe extending upwardly from the heater to the receptacle, smoke-pipes eX- tending downwardly from said receptacle, a pipe connecting the lower ends of said smoke pipes, and a discharge-pipe Whose lower end communicates directly with said connectingpipe, the said discharge-pipe extending upwardly first along the inner surface of the inner wall and then along the inner surface of the outer wall, substantially as described.

2. A drier having spaced inner and outer walls, the outer wall being continued upwardly beyond the inner wall, a receptacle supported above the top of the inner wall, a heater surrounded by the inner wall, a pipe extending upwardly from the heater to the receptacle, smoke pipes extending downwardly from said receptacle, a pipe connecting the lower ends of said smoke-pipes, and a discharge-pipe Whose lower end communicates directly with said connecting-pipe, the said discharge-pipe extending upwardly first along the inner surface of the inner wall and then along the inner surface of the outer wall, substantially as described.
