DETROIT, MICHIGAN BAKE OVEN j l Application filed April 22, 1929. Serial No. 356,967.
My invention relates to a new and useful improvement in a bake oven and has for its object theprovision of an oven with a maximum capacity and a minimum fire space or combustion chamber.'
It is another object of the present invention to provide abake oven of asingle furnace type or of a type having a single fire box of suflicient capacity to accomplish what 1s ordinarily accomplished by the` one furnace type of bake oven having a double set of fire boxes.
It is another object of the present invention to provide a bake oven of this class inwhich a minimum grate surface will be required, a saving of fuel effected and a minimum amount of time and labor required for ring.
Another obj ect of the invention is the provision of a bake oven of this class in which the loss of heat on account of radiation through'the walls may be reduced to a minimum.
Another object of the invention is the provision of an oven of large capacityhaving a 2,5 single damper mechanism.
Another object of the invention is the provision of a bake oven of the one furnace tunnel construction whereby the temperature of the oven may be raised to the proper degrec in a minimum amount of time and whereby the heating effects desired through the operation of the dampers may be accomplished most quickly.
Other objects will appear hereinafter.
The invention consists in the combination and arrangement of parts hereinafter described and claimed.
The invention will be best understood by 40 reference to the accompanying drawings which form a part of this specification and in which,
18 andthe inner'portion of the side wall-13 emerge into the passage 39, these gases havj are preferably formed from brick. Ala-yer 00 16 of Y'insulation is positioned between the outer walls and the inner wall 17- which is .also formed from brick. Projectingrearwardly from the front wall are bridge walls `or baffles 18'and'19 which, extend parallel 65 andinspaced relation to the forwardly eX- Atendingbridge walls or bafiles 20 whichproject inwardly fromthe rear wall 12`and serve to form thevfiie boX. A passage 21 is formed between` the bridge walls -19 and 20 and a 7o passage 22 is formed between the bridge wall 19`Hand theinner wall of the side Wall 14. A
The baiiiing of the gases and 'directing of the same into the passages indicated and through thepipe as located, permits the construction of the furnace inV such a manner that a single firing boX will suflice.` 'I he 'damper regulation also accomplishes a qulck variation of temperature in the oven.
n AIn the modified form shown in Figs. 7 andV A8 a baffle wall 50 is mountedto project upwardly from the base, this baffle wall cooperating with the' bridge wall 49 which is located at opposite sides of the grate 28 which is accessible through the doorsv 26 and 27. The
Vflue in this form of construction is at the lowlpassage 52 into theV outlet flue 53. The re- Vmaining, features of the structure as dethi's modified form and the advantages sought Y vfor in the preferred form are obtained in the f' modified form but for simplicity of structure and a maximum economy in operation, I pre fer to use the structure shown in the modified scribed for the preferred form are present in form.
IVhile I have illustrated and described the preferred fo-rm of my invention, I do not wish to limit myself tothe precise details of structure shown but desire to avail myself of such variations and modifications as come within the scope of the appended claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: Y y Y Y In a bake oven, a furnace construction, comprising: side walls, a front and rear wall, a topa-nd a bottom; a grate located at substantially the medial line of said structure adjacent its bottom and accessible through the j allel spaced relation and parallel to the side walls, said bridge walls terminating rear-v wardly of said front wall; baffle walls projecting inwardly from said front wall and extending between said bridge walls and the side walls; an oven compartment positioned above said furnace construction; aplurality of tubes projected through said oven compartment Vadjacent the upper side thereof and terminating with their ends in spaced relation to said fro-nt and rear walls7 the front ends of said tubes communicating through a passage with the space between vsaid side 'walls and said baffle'walls, and the rear end of lsaid tubes communicating throughl a passage with a chamber extending above said oven compartment, said chamber communivcating adjacent its forward side with'an outlet flue, the rear ends of' said tubes being 'ele vated relatively to the basefof said last mentioned passage; va deflectingmember projecting slightly inwardly of said iue at one end; andV a damper for opening and closing said enc. y
i In testimonyk whereofl I have Vsigned the foregoing specification.
