B'AKgRs QVELN.

Be it known that I, WILTON H. PERRY, a citizen of the United States, residing at Brooklyn, city of New York, in the county of Kings and State ofNew York, have invented certain new and j useful Improvements in- Bakers Ovens, of which the following is a specification. I

My invention relatesto improvements in bakers ovens; and the object of my invention-is to distribute the heat evenly through the baking-chamber to p In the ovens in use at the present time the upper part of the baking-chamber reachesa very high temperature, while the temperature ofthe lower partis much lower, and it requires a great amount of time to obtain an even temperature throughout the oven. By my arrangement of fiues, however, the

- heat is brought under the bottom of the bak- 'lineacac.

ture h at the floor near the front wall.

ing -chamber as well as in and above it, and an even, continual, and high temperature is readily obtained and retained.

'I attain this object bythe mechanism illustrated V in the accompanying drawings, in which Figure 1 is a vertical section of the device. Fig. 2 is a horizontal sectional view of'the chamber. below the baking-chamber on the Fig. 3 is a horizontal sectional view of the chamber above the baking-chamber on the line y 11 Fig. 4 is a-front elevation of the complete oven, and Fig. 5 is a view taken on line Z Z of Fig. 1.

Similar letters refer to similar parts throughout the several views.

My device consists of a baking-chamber a, preferably formed with a flat" floor I) and an arched roof 0. A heating chamber d is formed below the baking-chamber a andis provided with a dividing-partition e, extending from the front of the chamber to .the rear and provided with an aperture e near the front wall. A heating-chamber) is also provided above the baking-chamber .a, and is provided with a dividing-wall g, extending from the'front to the back. This dividingwall I prefer to make of iron, having a crosspiece g at the top and provided with an app}:-

e top of the chamber f is formed of a plurality of arched sheet-metal sections, each resting upon the cross-piece g on the dividing-wall at one edge and upon the projections & i in the side wall at the other edge. Earth or give the goods a uniform and continual bake.

other non-conducting material 7: is placed on top of these covers f The advantage of this arrangement is that the earth or other non- .conducting material 76 may be removed from the coversand the covers lifted for thepurpose of cleaning or repairing the chamber A vertical flue m is placed in the walls of the baking-chamber a and chambers d and f, preferably at the rear, having an opening m into the chamber (1 below the baking-chamber a and also having an opening m into the chamber f above thebaking-chamber a. A flue n is also placed in the walls of the baking-chambera and chambers d and f, prefer- ;ably at the rear, having an opening 77/ .directly into the baking-chamber a and extending upward to a point in the wall of the chamber f above the baking-chamber a and then downwardly beside the baking-chamthe chamber (1 below the baking-chamber a. An ash-pit'o is placed within and at one side of the chamber (1 below the baking-chamber a. Flues are also provided from the bakingchamber a to the .chimney and from the upper chamber f to the chinmey. Dampers g 1' are also provided in the several fiues in the usual form. A fire-grate s is placed in the floor of the baking-chamber a above the ashp1t 0. I

- The operation of my device is as follows: The fire 1s started on the floor of the bakingchamber a upon the grate s, and the gases will pass off through theflue 25. After the gases have passed off, the flue t is closed by the damper t, and the heated air after filling the baking-chamber a will pass through the opening n at the floor of the baking-cham- .ber a into the flue n, upwardly besidethe baking-chamber a and the upper chamber f and downwardly. through the continuation of the flue it, again beside the baking-chamwardly' through the opening m in the flue m beside the baking-chamber a and out through the opening m in the chamber f above the baking-chamber. The air in the side of this chamber f in which the opening it is situated will thus become heated, and

ber a to an opening n at or near the floor of v heated air from the chamber (1 will pass up- IIO the heated air will pass through the aperture h in the divided wally and out through the flue p to the chimney( The proper circulation of the heated air will be accomplished by the use of the several dampers in the usual form. The circulation of the heated air is shown by arrows.

I also rovide doors d d and f f 2 in the front wal of the chambers d and f, respectively, so that these chambers may be cleaned out when desired, the baking-chamber a being provided with the large doors a while a door 0 is provided for the ash-pit 0.

Having thus described my invention, what I claim is 1. In a bakers oven, the combination of a baking-chamber, a fire-grate in communication therewith, a chamber below and a chamber above said baking-chamber, the walls of said chambers formed with a plurality of fines, one of such flues communicating with the baking-chamber and passing upwardly and then downwardly to an opening near the floor of the lower chamber, and another of said fiues communicating with the lower chamber and passing upwardly into the chamber above the baking-chamber, and an exit-flue communicating with said upper chamber, substantially as described.

2. In a baker's oven the combination of a baking-chamber, a fire-grate in communication therewith, a chamber below and a chamber above said baking-chamber,a longitudinal dividing-Wall in said lower chamber having'an aperture therein, a longitudinal dividing-wall in said upper chamber having an aperture therein, the walls of said chambers formed with a plurality of fiues, one of such flues communicating with the baking-chamber and passing upwardly and then downwardly to an opening near the floor of the lower chamber, and another of said flues communicating with the lower chamber and passing upwardly into the upper chamber, and an exit-flue communicating with said upper chamber.

In testimony whereof I aflix my signature in presence of two witnesses.
