SFECIFICATEON forming parto-f Letters Patent No. 345,095, dated July 6, 1886.

Application filed July 7, 1885. Serial No. l70,S5l. (Nomodel.)

To all 'whom it may concern:

Be it known that l, HERMANN WILD, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvementsin Bakers Ovens, of which the following is a speciiication.

This invention relates to a bakers oven with two separate furnaces and heating-dues, whereby the oven is kept at uniform heat at a considerable saving of fuel.;J

In the accompanying drawings, Figure l represents a front elevation of my improved bakers oven. Fig. 2 is a horizontal section of the same on line x x, Fig. 1;'Fig. 3, a vertical longitudinal section on line y y, Fig. l; Fig. 4, a horizontal section on line e z, Fig. 8; Fig. 5, a vertical transverse section through the baking-chamber; and Fig. 6 is a horizontal section on line c c, Fig. 3.

Similar letters of reference indicate corresponding` parts.

Referring to the drawings, A represents the bakingchamber that gradually increases in width from the front opening toward the side walls, and which is lined with lire-bricks in the usual manner. rlhe bottom of the bakingchamber A is formed with tiles of iire-clay, which are laid on a bed of sand that is supported by lire-bricks having overlapping edges. rlhe bottom of the baking-chamber is made sloping toward the front opening, and is heated by means of two separate furnaces, B B, and by two systems of heating-dues, C C, by which the baking-chamber can be quickly heated and kept at a uniform heat. The gratos of thc furnaces B B are set back from the front doors, B B', and provided with separate fire-doors b, between which and the front doors spaces b are arranged, that communicate by vertical Ilucs I)L b'L in the front brick wall with a transverse top flue, C, leading to the chimney. rilhe ilues If ventilate the spaces in front of the grates and their ashpits and carry off the heated air. and dust, so as to give less trouble to the hands running the oven.

The longitudinal ilues C C run back from the furnaces toward the rear wall of the baking-chamber A, and communicate by vertical, rear lines, O', with longitudinal return-fines O2, which are located in the crown of the baking-chamber, and supported by double T- beams that rest on a transverse iron plate, d', at the front part of the baking-chamber, and on the transverse rear wall of the same, as shown in Fig. 3.

The return-lines Cl C2 are formed of top and'bottom tiles of fire-brick, which rest, respectively, on the bases and tops of the double T-beams, and of vertical side-bricks, which cover the webs of the beams, as shown in Fig. 5. The return-lines C2 C2 form with the beams and tiles described the crown of the baking-chamber and heat the-upper part of the same.

rlhe crown of the baking-chamber A is provided in its rear part with a central opening, e, that communicates by a central flue, e', with the transverse top-line, C. The opening c is closed by a sliding damper, E, the damper-rod Eof which passes through the front wall ofthe oven, and has a handle at its outer end, so as to be conveniently operated for admitting the escape of steam and heated air from Ythe baking-chamber through the ilue c to the chimney, and relieving the baking-chamber from undue steam-pressure. The return-fines CIl CZ are open at their front ends and connected by two short vertical lues, O, with a second lateral ilue, C5, which communicates with the chimney. The vertical ilues O are provided with horizontal dampers F-and damper-rods F', which extend through the front wall and are operated from the front of the oven. By closing the dampers F F the iiregases do 'not pass through the return flues C2 O2, but through a central and side top flue, G, directly to the transverse front Hue, C5, as shown in dott-ed lines in Figs. 3 and 6. The dampers F are closed when the iire is started in the furnaces and also when the oven is thoroughly heated, so that the heat of the same is thereby regulated to the proper degree of temperature. A layer, f, of asbestus, eX- tends over the bricks that cover the returnilues C2 to the rear part of the structure, also a second layer, f, vertically through the rear wall of the baking-chamber, which layers serve to conline the heat in the baking-chamber and prevent the radiation of the same through the top and rear brick walls.

Having thus described my invention, I In testimony that I claim the foregoing as claim as new and desire to secure by Letters my invention I have signed my name in pres Patentence of two subscribing witnesses.
