IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 4 l,l4l5, da'ed February 16, 1864.

To all whom it may concern.-

Be it known that I, JOSEPH SHOLL, of Burlington, Burlington county, New Jersey, have invented an Improvement in OoohingStoves and Ranges; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention consists of a fire-chamber, hotair chamber, and oven, arranged as described hereinafter, vin combination with a system of fines, the top of the oven being heated by the products of combustion only, while the desired heat is imparted to the front, bottom, and rear of the oven by hot air, the object of my invention being the attainment of simplicity as regards the construction of the stove or range, economy as regards the consumption of fuel, and the prevention of the accumulation of soot and dirt in the flue beneath the oven.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a vertical section of my improved cooking-stove Fig. 2, a sectional plan on the line 1 2, Fig. 1, and Fig. 3,a transverse vertical section on the line 3 4, Fig. 2.

Similar letters refer to similar parts t-hrou ghout the several views.

A is the top plate of the stove; B, the rear plate; 0, the frentplate; :D, the bottom plate, and 'E and E the opposite side plates.

Near the front of the stove is the lire-chamber F, furnished at the bottom with an appropriate grate, a, beneath which and the bottom plate, D, of the stove is the ash-chamber G, containing a detachable drawer, 1), air for supporting the combustion of the fuel being admitted to the ash-chamber through openings in the front plate, 0, of the stove or in frontof the ash-drawer, which openings may, it'deemed necessary, be furnished with suitable valves or registers for regulating the admission of air. The fire-chamber F has a direct communication with the horizontal flue H, situated be tween the top plate, A, of the stove and the top plate of the oven X, this fine communicatin g with the outlet 01, through which the products of combustion pass into the pipe communicatin g with the chimney.

I is the hot-air chamber, bounded laterally by the opposite side plates, E and E, of the stove, longitudinally by the front plate, 0, and a plate, J, and separated from the ash-chamber G by plates which may form continuations of the rear and side plates of the fire-box. In front of the fire-box is a space, K, which may communicate with the hot-air chamber I, there being a door, 0, in front of this space. In the bottom plate of the stove are a series of openings,ff, (see Figs. 2 and 3,) for the admission of air to the chamber I. A vertical air-fine, L, intervenes between the front plate ,M, of the oven and the plate J, the flue being continued horizontally beneath the oven, and vertically between the rear plate N of the latter and the rear plate B of the stove, and communicating through the two openings 72 n with the rearof the flue H at the point where the latter communicates with the outlet d. The products of combustion pass directly from the firechamber through the horizontal fine H to the outlet 01, and suffice to impart the desired heat to the top of the oven and to such culinary vessels as may be deposited in the usual circular openings in the top plate, A, of the stove. The air admitted through the openings f to the chamber I is brought into intimate contact with the exterior of the tire-box F, and must of necessity be highly heated before it can pass through the opening 00, Fig. 1, into the vertical fine L. As this flue communicates with the outlet (1-, and as the passage through the same outlet of the products ot'combustion tends to cause a partial vacuumin the flue at the rear of the oven, there must be a constant current of heated air through the flue L, and thence beneath the oven and in contact with the rear of the same. While the products of combustion, therefore, serve to heat the top of the oven, snfficient heat is imparted to the front, bottom, and rear of the same by the air heated in the chamber I. 1

I have found by repeated tests that a much less fire-chamber and much less quantity of .fuel are required for thoroughly heating the oven in a stove constructed as described above than in stoves heated by causing the products of combustion to pass beneath as well as above the oven, and that the heat is of that uniform character so desirable in cookingstoves and ranges. A suitable valve, m, serves ito regulate the passage of the products of It will be evident that the stove is, as re ga-rds general construction, of the most simple character and that no soot or dirt can accumulate in the flue beneath the oven and interfere with the proper heating of the same.

I claim as my invention and desire to secure by Letters Patent-- The fire-chamber F, hot-air chamber 1, and oven X, arranged as set forth, in combination with the system of fines herein described, whereby the top of the oven is heated by the products of combustion only, while the necessary heat is imparted to the front, bottom, and rear of the oven by the air heated in the chamher I, as set forth, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH SHOLL.
