UNITED u. STATES PATENT OEEICE.

SAMUEL ELLIS, OF ST. LOUIS, MISSOURI.

HEATER AND COOKER. l

SPECIFICATION forming part of Letters Patent No. 260,856, dated July 11, 1882.

Application filed August 23, 1880.

To all 'whom it mag/concern:

Be lit known that I, SAMUEL ELLIs,'of the city of St. Louis, in the State of Missouri, have invented a new and useful Improvement in 5 Heating and Cooking Apparatus, of which the following is a specication.

Myinvention relates to heating and cooking apparatus of .the description shown in Letters Patent ofthe United States granted Daniel K.

1o Boswell November 20, 1,877, and numbered 197,321, which consists of a case or box con.- taining a furnace or fire-box, a removable cooker or heater, and a hot-air flue communicating between them.

My improvement consists in insulating the furnace or tire-place from the surrounding wooden case by an intervening layer of air, and by holding it out of contact with the case at every point. This I accomplish by supporting 2o the iron box on hollow sheet-iron braces. My

2 5 highly dangerous.

object in so doing is to get rid of the conduction which would takeplace were continuous walls or partitions used between the iron box and the case, which with a wooden case is This insulation from heat by conduction is still further secured by the'use of the hollow braces, which reduce to a minimum contact with the external wooden case.

In the accompanying drawings, which illus- 3o 'trate my invention, Figure l is a front view 4o in section of the entire apparatus, showing the l relation of the furnace, the removable drierlchamber or cooker, the dedecting-ch amber, and the exterior case; and Fig. 8 is a View insection of part ofthe apparatus, showing the rei lation of the deflecting-cha-mber to the furnace and the removable drier-chamber.

A is a case of wood, and, as in the patent above' referred to, contains a lower section, B, Fig. 3, which is the furnace, and an upper sec- 5o tion, C, Fig. 4, which is the cooker or drierchamber. Section Bconsists of a sheet-iron (No model.)

box,'D, held ont of contact'with'the sides of case A by hollow sheet-iron braces a. The top and bottom plates ofbox D are perforated near their edges with small holes b, Fig. 3. `The top and bottom platesare similar in every respect and the perforations similarly disposed in each. This is done to facilitate the circulation ofthe heated air.

E-is thev fire-place, of oval form, having a continuous outer wall, F, to protect case A from' the heat of the fire-place, and an inner perforated wall, G, which keeps the fuel out of contact with wall F.

H is the grate, sliding on braces I, and having a nib, K, which fits the fork of the key or handle L, by which it is shaken. The key L is inserted through the opening 7c in front of case A, through which the ashes are removed and the air supplied to the tire, or it may be rigidly attached to the grate.

M is the smoke-fine, N the flue-box, and O the smoke-exit pipe. y

P is the usual opening, which may be either oval or circular, in the top of the furnace for the reception'of pots, pans, or other cookingvessels.

Directly under the' smoke-exit pipe O is a triangular opening, q, extending through case A into the space between it and the sides of insulated box D for the purpose of cleaning the perforated lining. This opening is closed by the lid Q, Fig. 5when not in use.

The removable cooker or drier-chamber C, Fig. 4, which constitutes the upper section of the entire apparatus, has all four of its sides perforated to admit of the circulation of the heated air through allits parts. It is provided with hangers R, of galvanized iron or other suitable material. These hangers form seats for wooden bars S, and greatly facilitate the removal of the bars and the adaptation of the cooker, to the sides of which they are riveted or otherwise attached to other purposes.

T is an opening into the cooker for the admission of external air when desired.

U, Fig. 7, is the detlccting-chamber that de-I` llects the heat from the furnace to the cooker or drier-chamber C in a well-known way.

In Fig. 3 I have shown the grate H as resting on braces I. It may also be centrally pivoted to and supported by a single central cross- IOO brace, as shown at i, Fig. 6, the braces I being dispensed with. It is obvious that the form ofthe grate may be either oval or circular.

By the above improvement I secure a complete insulation ofthe furnace from the outside Wooden case and interpose a medium of constantly-changing air7 which greatly protects the case from the radiation of heat from the furnace, While the insulation protects it from conduction, both of which are asource of danger. This security I further increase by the double Walls of the fire-place, which prevent the frequent burning out ofthe tire-placean objection to the abovenamed patent.

I am aware that heating, cooking, and drying apparatus have been made consisting of a case containing a furnace, a removable drier, and cooker, with a hot-air delector communieating between them. Such an apparatus is described in Boswells patent, before men tioned; but

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

l. rIhe combination, in a heater, cooker, and drier, of the outer wooden shell or case and the iron box containing the tire-place, said iron box being vertically, laterally, and immovably braced against and insulated from the wooden shell, substantially as and for the purpose herenbefore set forth.

2. The combination, in a heater, cooker, and drier, ot' the outer Wooden shell or case, the iron box containing the tire-place, and hollow iron braces which brace the iron box vertically, laterally, and immovably against the wooden shell, and also support the Wooden shell and iron box wholly out of contact with each other, substantially as and for the purpose hereinbefore set forth.

SAMUEL ELLIS.
