PATENT LEVI R. COMSTOOK, OF RICHMOND, VIRGINIA.

IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 159,797, dated February 16, 1875; application filed October 10, 1874.

To all whom it may concern Be it known that I, LEVI RICHARDSON GoM- STOCK, of the city of Richmond, in the county of Henrico and State of Virginia, have invented a new and valuable Improvement in Stoves and Heaters and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a transverse vertical section of stove and and heater. Fig. 2 is a front view of the same; and Fig. 3 is a longitudinal vertical sectional view. Figs. 4 and 5 are transverse sectional views.

This invention has relation to stoves and heaters, which are designed for drying tobacco, and also for all purposes where hot air and radiated heat can be made available.

The nature of my invention consists in a novel arrangement of flues and partitions inside of a casing, in combination with a furnace-chamber and air-inlets, whereby a very large radiating-surface is obtained for heating air, and, at the same time, every facility is afforded for cleaning the fines, as will be hereinafter fully explained.

It also consists in a novel provision for heating water for the purpose of steaming and softening tobacco-leaves, so that they can be properly handled, as will be hereinafter explained.

The following is a description of my improvements:

In the annexed drawings, A designates the furnace of the heater, and B the outer shell, which I prefer to make of an elliptical form, as shown in the drawings. D designates the furnace-door, and D an outlet for the heated products of combustion, which outlet leads into a chamber, E, communicating with the rear ends of two flues, GG. These flues conduct the products of combustion forward, and deliver them into a chamber, IE at the front end of the heater.

From the chamber E the products are carried back through two fines, G G and delivered into chambers E at the rear end of the heater. The products are again carried forward through flues G and delivered into a chamber, E from which they enter a large flue, F, and proceed backward nearly to the rear end of this flue, and finally escape through the pipe F.

The chambers E IE at the front end of the heater, are formed by the division-plates I) 0, and the chambers E E E at the rear end of the heater, are formed by the divisionplates a a a.

When the damper p, shown in Fig. 3 near the rear end of flue F, is opened, the products of combustion pass directly off through the pipe F, and do not circulate through the fines.

The front and rear end plates of the heater have holes through them, which register with the several flues, and are of the same diameter as their respective fines, for the purpose of allowing these fines to be conveniently cleaned out. The said holes are closed by hinged doors 0 O, or, instead of doors, stoppers may be applied.

On top of the heater-case B is a cylindrical outlet, H, for hot air, in which a damper, K, is applied for regulating the escape of hot air. When the damper K is open, a boiler, J, with outlet-pipes J, is applied in H for the purpose of generating steam for moistening tobaccoleaves. On one side of the case B, near the upper end thereof, are several outlet-pipes L, the object of which is to conduct hot air into' a tobacco-barn for curing tobacco, and when this process is completed the large damper K is opened and the heat allowed to escape outside of the barn.

In practice, I shall surround the furnace A with fines, and locate the furnace in the center of the cluster of lines. The furnace will be adapted for hard or soft coal or for burning Wood, and it will be portable.

What I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a furnace, A, and chamber E, the flues G G, communicating with the front chamber E, the lines Gr G with the rear chamber E and the fines Gr G with the front chamber E, from which the products of combustion enter and escape through the pipe F, substantially as and for the purpose set forth.

FFIGE.

2. In a furnace, the combination of the (lihereunto subscribed my name in the presence vision-plates b 0, forming the chambers 1:]; E of two witnesses. at the front end of the heater and the ivision-plates a a a, forming the chambets E E Y RICHARDSON COMSTOCK' E at the rear end, substantially as and for Witnesses: the purpose set forth. A. S. JOHNSON,

In testimony that I claim the above I have WM. HALL CREW.
