MULTIPLE BAKERS OVEN.
Specification of Letters Patent.
Patented May 11, 1920.
substitute for application serial Noi 148,555, filed February 14, l1917. This application med Maron 3,
` 1919. Serial No. 280,384.
To allpwhom it may concern .W Be it known that I, OTTO WUNDRAOK, a citizen of the United States, residing at Maywood, 'in the county of Cook and State of Illinois, have invented new and useful Improvements in Multiple Bakers Ovens,-
was limited to its predetermined estimatedy capacity, and if it were desired to increase this capacity the oven had to be torn down and rebuilt, or additional independent ovens installed.
The object of my invention is to build amultiple bakers oven of several correspond-- ing oven-units, each of which is complete in itself and yet can have another unit or units added thereto in alinement to increase the capacity and expedite the work thereofl as desired. A further object is to accomplish a saving of fuel when the oven has two or more units by allowing the furnace in one unit to die out and utilize the heat generated in the other units to heat the entire oven structure. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.
In the drawings:
Figure 1 is a longitudinal vertical section of a single unit of my improved multiple bakers oventaken on dotted line l, l, Fig. 3.
Fig. 2 is a similar section of several of said units assembled into one continuous oven, drawn to a smaller scale.
Fig. 3 is a transverse vertical section taken on dotted line 3 3, Fig. 1.
Referring to the drawings, A represents the front-wall of the front unit of my improved bakers oven; B, B, the side-walls thereof; C the roof, andD the rear end wall of the same. This front oven unit is built on a suitable foundation and is partially surrounded by a suitable areaway and is heated by two ,transversely arranged furnaces; one, a, is built partly below the plane of the foundation of the oven just back of the frontwall, and the other, I), is built in about the same level in about the same relative position, to the rear end-wall D of the same. Furnace ,a is generally used to assist in raising the temperature to obtain thedesired heat to start the oven, and it `is customary just as soon as the rear furnace is operating satisfactorily and the temperature of the oven is high enough to let the front furnace die out. At the left hand end -of these furnaces (which terminate about midway between the side-Walls of the oven) their side-walls and a-rches terminate and dischargeY into the longitudinally disposed heat-chamber E, which latter is arched over by a suitable arch c, and the heated'products of combustion discharge therefrom through a verticalvalve controlled flue d into an ante-chamber e located over the entrance of the bakingchamber of the oven right back of the front- .vvall thereof.
. The roof of this ante-chamber is `provided with a suitable opening up through which the products of combustion candischarge into the horizontal chimney-flue that extends immediately above the roof of the oven and leads direct to the chimney (not shown). This opening is closed by a plate-valve F that has a suitable rod extending longitudinally therefrom out through the front-wall and terminates in a suitable handle that can be grasped to operate the valve whenever desired. This antechamber; when valve F is closed, discharges rearwardly into a series of longitudinal tubes G that extend through the upper portion of'and practically form the ceiling of the baking-chamber H, and the rear ends of these tubes discharge into dischargechamber g. Chamber g has an opening in its ceiling by means of which said chamber can communicate directly with flue f that leads to the chimney, and a horizontal platevalve 7L which is movable transversely, closes or controls the area of this opening.l
Front-wall A of the oven is provided with a transversely arranged series of longitudinally extending openings therein that aline with tubes Gr and thefront ends of these openings are closed by 'suitable covers z' by removing which access can be had to said is closed by a suitable cover 7c. At a suitable point betweenl its ends, passage I has a vertically disposed transverse plate-valve .K therein which is reciprocable transversely to control the opening of said passage.
The baking-chamber H extends from one end to the other of the oven-units, and it is open at both ends, and between this bakingchamber and heating-chamber E there is a longitudinally disposed reheating-chamber J which extends the entire length of. the oven-unit just. above arch c and'is open at both endsf Both the baking-chamber and the reheatingfch'amber of the front unit have tracks m, n, respectively, the-ends of which when said unit is alone used extend out of the open ends of the baking-chamber and reheating-chamber a short distance. A suitably constructed traveling hearth (Which, together with conjunctive devices, is made the subject-matter of an application for Letters Patent of the United States filed March 15, 1919, Serial No. 282,898) is'supported on these tracks as it travels rearwardly through the baking-chamber and returns forwardly through the reheatingchamber. Thel ends of this endless hearth pass around suitable sprocket-wheels M, N,
respectively, which latter areA inclosed with- I in rectangular shaped housings O, P, in order to prevent the escape of the heat. The details of construction of these housings are immaterial in so far as myinvention is concerned.
The rearwall of the oven just above the plane of furnace b is provided with a longitudinal passage Q, which is providedwith a transversely movable valve-plate R, and has its rear end closed by a suitable cover g. When it is desired to enlarge and increase the capacity of this front oven-unit, the
rear-wall of the same is utilized as the frontwall of the added rear oven-unit, -which latter, as shown in Fig. 2 of the drawings, is constructed so as to provide a rearwardly extending continuation 4' of the chimneyflue f. The roof 5 of this-added oven-unit is in the same plane as roof C ofthe front unit and arches over the baking-chamber 6, which latter corresponds to and is a continuation of baking-chamber H of the. for wardmost unit and extends through its own rear-wall 7. This rear unit also has areheating-chamber 8 which corresponds with and forms a continuation of reheatingchamber J of the front oven-unit, and it also extends through its rear-wall 7 and is open at its rear end. This rear oven-unit is also provided with a heat-chamber 9 which receives the heated products-of combustion from a transversely disposed furnace 10 adjacent rear-Wall 7 thereof, which is built in the same level as furnaces a and I) of the forward oven-unit and corresponds in construction thereto.
When passage Q is closed by valve R the products of combustion from heat-chamber 9 dischar es into a vertical valve-controlled lue 12, t e lower end of which is o enl t0 chamber 9 immediately to the rear o rearwall D of the front oven-unit. This vertical flue extends up through the side-wall of the rear unit of the oven and discharges 'at its upper end into a transversely disposed ante-chamber` 13, the dimensions of which,
preferably, correspond to chamber to which latter it is. connected by passa e I. The top of this ante-chamber 13 is c osed by a transversely movable valve 14v that corresponds in `construction to valve h of receiving-chamber g, and chamber 13 is connected by a series of longitudinally7 disposed4 tubes 15 correspondingto 'tubes g) to a discharge-chamber 16 built in the furnace structure above the dischar e end of baking-chamber 6. Discharge-c amber 16 discharges into flue 4 immediately in front of rear-wall 7 of the rear oven-unit, and this discharge is controlled by a horizontally disposed laterally movable plate-valve 17 that corresponds in construction and. operation to late-,valve 14.
en it is desired to operate the multiple bakersoven shown in Fig. 2l of the drawings, furnaces a, b and 10 are started, and at first the products of^ combustionjfrom furnace a discharge into verticalflu'e d in the side-Wall op osite the entrance to fui'- nace a, and ldiscli j the oppositely located lower end of a vertical valve-controlled flue S, which latter extends through the same side-wall in which flue d is made, and discharges into one endy of exit-chamber g, and the products of com,- bustion from furnace 10' dlscharge into the lower end of a vertically disposed valvecontrolled flue 18 which is made in the same side-wall as lues e and S and `from thence into one end of the transverse exit-chamber 16.
After the oven has'A become suiciently heated, valves K and R are opened and flues S, 12 and 18 are closed by plate-valves similar to that in flue d, but not shown in the drawings, and valves F, It and 14 are closed and valve 17 opened, whereupon the heated products of combustion from furnaces 10 and?) will flow forward through heatingchambers 9 and E up through flue d into ante-chamber F and from thence rearwardly through tubes G- that heat the baking-oven of the front oven-unit and rearwardly through chambers'g and 13, and tubes 15.
arge from furnace b -into chimney. After the oven has become suficiently heated, furnace a is permitted to die out, and the heat from furnaces b and 10 are depended upon to obtain the necessary temperature for the baking and reheating chambers of the oven. In very warm weather furnace b may also be permitted to die out and the heat from furnace 10 can be relied upon to provide the necessary heat for the oven.
From the construction of my improved multiple oven, as hereinbefore described and as illustrated in the drawingsit will be apparent that valves K and R can Abe closed and valve h opened and the front oven-unit be operated. without the rear oven-unit, or, if desired, the front oven-unit could be cutout by closing valves K and R and the rear unit be operated. It is also apparent that, if desired, a third oven-unit could be added to the oven structure in the same manner as vthe rear unit, hereinbefore described and as illustrated in the drawings. By increasing the length -`of the oven by the additional oven-units it is possible for a baker to first build the forvvard-unit and rely upon it for his output until he is financially able to add a secondy oven-unit thereto, and so on, for the longer the oven the more bakery goods can be baked with a relatively greater'economy in time and fuel than could possibly being chambers that return forward through said reheating-chamber.
