BAKER S OV EN.

SPECIFICATION forming part of Letters Patent No. 534379, dated February 19, 1 895.

Application filed August 25,1894. Serial No. 521,284. (No model.)

To all whom it may coi worn:

Be it known that I, ERNST SCHILG, a subject of the Emperor of Germany, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bakers Ovens, ofwhich` the following is a specification.

The object of my invention is to obtain such results as may be naturally attributable to the Construction hereinafter set forth, the especial features of novelty being enunerated in the claim at the end of the specification.

In the accompanying drawings: Figure I represents a horizontal section of an oven embodying myinvention, the plane of section being indicated by the line 1-1, Fig. VII. Fig. II represents a like section thereof in the plane indicated by the line 2-2, Fig. VII, looking downward. Fig. III repres'ents a like section thereof in a like plane to the preceding figure, looking upward. Fig. IV represents a like section thereof in the plane indicated by the line 4-4, Fig. VII.- Fig..V represents a like section thereof in the plane indicated by the line 5-5, Fig. VII. Fig. VI represents a plan View thereof. Fig. VII represents a cross-section thereof in the plane indicated by the line 7-7 Fig. I. Fig. VIII represents a front view thereof. Fi g. IX represents a Vertical section of a portion of the front wall thereof in the plane indicated by the line 9--9, Fig. IV. p

Similar letters of reference indicate similar parts in all the figures. The letter A indicates the hearth orbakingchamber, B the fire-chamber, and C, D, air-` chambers above and below the baking-chamber. The air-chamber C is below the baking chamber A between it and the fire-chamber B and the air-chamber D is above the bakingchamber; and the last named air-chamber has outlets D' each provided with a damper D The air-chamber D communicates with the fire-chamber B by means of flues e, in this example two in number which are formed in the rear wall of the oven, opposite to the front wall thereof, in which latter are two openings with doors F, Gr, one' affording access to the baking-chamber and the other to the fire- -chamber.

The longitudinal passages on either side of the fire-chamber B lead directly back to the flues e, and said passages at their forward ende are open laterally toward the fire-place while at their rear ends they communicate with the rear of the fire-chamber. The draft through the flues draws the fire from the fireplace laterally into said longitudinal passages as well as backward, and consequently when the door of the fire-chamber is opened there will be no forward Shooting of flame as is the case when there are flues at the front of the oven.

By the location of the flues e only in the rear wall, in contradistinction to the front wall of the oven, the attendant baker is relieved from the heat which would otherwise radiate from the front of the oven.

The door F, to the baking-chamber is hinged, as at F' (Fig. IX) and is weighted in such a manner as to counter-balance, that is to say, the door will automatically retain any position to which it may be adjusted; the weight used for this purpose being an integral part of the door.

The top or partition wall dividing the baking-chamber A from the air-chamber D is arched as shown in Fig. VII and at the center thereof is a lon gitudinal beam H of metal, which is anchored in the front and rear walls of the oven, the purpose of this beam being to prevent warping of said partition wall under the influence of the heat to which it is subjected.

Both air-chambers C and D are divided into compartments, as shown in Fig. VII; but may be continuous.

The purpose of the air-chamber C is to attemper the heat of the fire-chamber B, in its action on the baking-chamber; and it is evident that said chambermay be omitted.

hat I claim as my invention, and desire to secure by Letters Patent, is-- In a baker s oven having a fire-chamber' with a fire-place at the front end thereof and a baking-chamber above said fire-chamber,

vertical flues e in the rear wall of the oven,

extending to the top of the oven above said baking chamber, longitudinal passages `on either side of said fire-ehamber communicatng only with said reat' flues and. with said fire-chambe' at its front and real' ends, the front openings from the fire-chambe' to said passages being located directly at the side of the fire-place, whereby heat and flame are drawi laterally and real-ward from said fireplace to said rear fiues, substantially as set Io fol-th.

ERNST SOHILG.
