BERNARD MEYER, OF PHILADELPHIA, PENNSYLVANIA.

BAKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 783,215, dated February 21, 1905.

Application filed J une ll,

To all whom, '1125 may concern:

Be it known that LBERNARD MEYER, a citi- Zen of the United States, residing' in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful 1mprovement in Bake-Ovens, of which the following is a specification.

My invention consists of a bake-oven 'in which provision is made for heating the floor, the roof or arch, the interior of the bakingchamber, and both sides of said chamber, provision being' also made for cutting off certain courses of heating when so desired, as will be hereinafter described, the novel features being' pointed out in theclaims.

Figure l represents a vertical section of a bake-oven embodying my invention on line a' Fig'. 2. Fig. 2 represents a partial plan view and partial horizontal section thereof. Fig. 3 represents a vertical section on line y y, Fig. l. Fig. 4l represents a vertical section on line .e 2, Fig. l. Fig. 5 represents a horizontal section on line a ct, Fig. 1.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the body of the oven, and B the furnace thereof.

' C designates the hearth of the oven,between which and the floor D of the baking-chamber E is the Hue F, the upper Wall or ceiling' of which is composed of a series of arches,whereby the products of combustion or heat admitted into said iiue E impinges successively against the several scallops or arches, thus effectively heating the same, the effect of which is communicated to the iioor of the chamber E, it being seen that the furnace B is in communication with said ue E, as most clearly shown in Fig. 1.

Gr designates avertically -extending tube which passes through the iioor of the oven and communicates with the flue F, said tube being connectedwith the pipe H,which is located in the chamber E, and passes around one side of the oven, the back, and the other side thereof, and its terminal .l is in communication with the chimney or stack K.

At one end of the body, in the present case the left-hand end thereof, is the vertical iiue L, whose lower end is in communication with 1904. Serial No. 212,103.

- the rear of the flue E, the upper end of which is in communication with the horizontallyextending flue M, which passes diagonally over the arch or roof of the chamber E and has its terminal connected with the pipe P, the latter opening into the iiue or stack K, it being' noticed that one end of a horizontally-extending flue Q opens into said pipe P, said flue Q and pipe being in the right-hand side of the body, it being noticed that one end of said iue Q is connected with the vertical flue R, the lower end of the latter being in communication with the flue F, whereby the products of combustion from the latter' may be admitted intov the flues R and Q, it being noticed that the flue Q at its terminal communicates with the iiue P, and thus is in communication with the chimney or stack K. Connected with the terminal of the Hue M is the damper S, and connected with the flue P is the damper T.

The operation is as follows: The products of combustion leave the furnace B and enter the flue E in the direction of the arrows l, thus heating the ceiling or roof of said flue, the effect of which is transmitted to the floor of the chamber E, whereby said floor is in a highly.- heated condition. The products of combustion enter the pipe H and traverse the same along one side of the chamber E, the back, and the other side thereof Within the chamber E, as indicated by the arrows 2, thus effectively heating said chamber, the products of combustion then entering the chimney or stack K. Should it be desired to heat, say, the left-hand side of the chamber E, the damper S is opened, whereby the products of cornbustion rise in the flue L, and thus heat the adjacent portion of the body A, (see arrows 3,) the products of combustion then entering the pipe M, which passes over the roof or arch of the chamber E, (see arrows 4,) thus heating said roof or arch, the effect of which is communicated to the top or upper portion of said chamber. When the products of combustion leave the iiue M, they enter the iiue P, and so reach the chimney or stack, the damper T having also been opened. Should it be desired to heat the right-hand side of the chamber E, the damper S may be closed,where- IOO by some of the products of combustion enter the Hues R and Q, as shown by the arrows 5 and 6, thus heating the corresponding portion of the body A, the products of combustion then reaching the chimney or stack through the Hue P, (see arrow 7,) the Hues M and Q, being confluent at the Hue P. If desired, both dainpers S and T may be opened, whereby the products of combustion entering the Hues M and Q, are conHuent at the Hue P, and so reach the chimney or stack, as per arrow 7, it being evident that by these means an oven may be effectively heated from within, from below, above, and at its opposite sides all at one time, or some of the courses may be cut oH, this being accomplished by suitably opening and closing the relative dampers.

Various changes may be made in the details of construction shown with out departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. An oven having a Hue leading from the furnace below the Hoor of the baking-chamber, vertical Hues common to said furnace-Hue at opposite corners thereof, a pipe extending' from one of said vertical Hues around the sides and back of the oven within said bakingchamber, a top Hue above the roof of the balzing-chamber communicating with the other vertical Hue, anl exit-pipe with which said top Hue is in communication, an auxiliary vertical Hue leading from the furnace-Hue and a horizontally-extending Hue extending from said auxiliary yvertical Hue and beingconHuent with said exit-pipe.

2. An oven having a Hue leading from the furnace below the Hoor of the baking-chamber, vertical Hues common to said furnace-Hue at opposite corners thereof, a pipe extending from one of said vertical Hues around the sides and back of the oven within said baking-chamber, a. top horizontal Hue above the roof of i the baking-chamber communicating with the other vertical Hue, an exit-pipe with which said top Hue is in communication, an auxiliary vertically-extending Hue leading from the furnace-Hue, a horizontally-extending Hue extending from the auxiliary vertical Hue and being conHuent with said exit-pipe and dampers in different members of the conHuent Hue and pipe.

3. An oven having a Hue leading from the furnace below the Hoor of the baking-chamber, vertical Hues common to said furnace-Hue at opposite ends thereof, a pipe extending from one of said vertical Hues around the sides and back of the oven within said baking-chamber, a Hue above the roof of the said chamber communicating with the other vertical Hue and extending diagonally therefrom, an exit-pipe with which the diagonal Hue is in communication, an auxiliary vertically-extending Hue leading from the furnace-Hue, and a horizontally-extending Hue extending from said auxiliary vertical Hue and being conHuent with said exit-pipe.

4. An oven having a Hue leading from the furnace below t-he Hoor of the baking-chamber, vertical Hues common to said'furnace-Hue at opposite ends thereof, a pipe extending from one of said vertical Hues around the sides and back of the oven within said baking-chamber, a horizontal Hue above the roof of the said chamber communicating with the other vertical Hue and extending diagonally therefrom, an exit-pipe with which the diagonal Hue is in communication, an auxiliary vertically-extending Hue leading rfrom the furnace-Hue, a horizontally-extending Hue extending from said auxiliary Vertical Hue and being conHuent with said exit-pipe, and dampers in different members of the conHuent Hue and pipe.
