Description
ELOF NELSON, OF OAK CREEK, COLORADO.
BAKERS' FURNACE.
Specification of Letters Patent.
Patented Jan. 21, 1919.
Application filed June 13, 1918. Serial No. 239,859.
To all whom it may concern:
' Be it known that I, ELOF NELSON, a citizen of the United States, residing at Oak Creek, in the county, of Routt and State of Colorado, have invented certain new and useful Improvements in Bakers Furnaces, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to bakers furnaces,
and has for its primary object to provide a bakers furnace with a double chambered baking oven, and means for effecting an equal distribution of the heat from the furnace to the oven chambers when both chambers are being used. It is another important object of my invention to provide means for radiating and controllin the heated air so that the baking cham ers of the oven will be heated throughout their areas to a substantially uniform temperature.
The invention also has for an additional object to provide a bakers furnace as above characterized which will be exceedingly strong and durable in its construction, and in theuse of which highly satisfactory results may be obtained in the baking of bread, pastries and like products.
With the above and other objects in view the invention consists in the improved construction, combination and arrangement of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate corresponding parts throughout the several views, and wherein Figure 1 is a vertical sectional view through a bakers furnace and oven constructed in accordance with the preferred embodiment of the invention;
Fig. 2 is a transverse section taken on the line 22 of Fig 1; and
Fig. 3 is a similar section taken on the line 3-3 of Fig; 1.
Referring in detail to the drawing, 5 designates the front wall of the furnace, 6 the rear wall thereof, 7 the top wall, and 8 the base wall. These furnace walls may be of any desired construction and if preferred may be suitably reinforced and insulated in any approved manner.
A fire box 9 is centrally disposed between the side Walls of the furnace structure, and
at its front end communicates with a trans vertical passage or flue 12 in the rear wall 6 of the furnace structure.
Spaced floors or decks 13 are suitably mounted and secured within the upper portion of the furnace and extend the full length and width thereof, said floors separating the interior of the furnace into upper and lower baking chambers 14 and 15 respectively. The top Wall of the fire box 9 extends substantially the entire length of the furnace and between said wall and the lower floor or deck 13, a horizontal metal wall 16 is arranged and suitably supported upon the side and end walls of the furnace. Between the top of the fire box and the wall 16, a partition wall of masonry indicated at 17 is disposed, said wall separating the smoke passages or chambers 11 from each other. The space between the horizontal metal wall 16 and the floor 13 of the lower baking chamber 15 constitutes a hot air chamber 18. At the rear end of the furnace structure between the wall 16 andthe floor 13, a bridge wall 19 is disposed and is provided with a plurality of ports or openings 20 communicating with a vertical flue 21 which is disposed within the smoke flue 12. This flue extends upwardly along the rear wall 22 of the'oven proper. The top wall 23 of the oven is spaced from the top wall 7 of the furnace structure to provide a longitudinally extending passage 24 over the oven which is in communication with the smoke flue 12.- At its forward end the passage 24 communi. cates with the smoke stack 25, through the ports or openings 27 in a bridge wall 26. Preferably, suitable braces or stays 28 are arranged at intervals between the top wall of the furnace and the top wall 23 of the oven, and similar braces 29 are also varranged between the horizontal wall 16and the floor plate 13 of the lower oven chame ber 15.
A feed door 30 for the fire box 9 is arranged in the rear wall 6 of the furnace structure, and suitable doors 31 are also mounted in the front wall of the furnace to afford access to the respective oven chambers. These doors are equipped with suitable air inlet valves. I may also provide 1 25 This plate is provided with a suitable operating rod indicated at 3 1 extending forwardly at one side of the hood 33.
The side walls 35 of the furnace structure are formed with the passages 36 therein,
' which are, in communication at their lower ends of the hot air chamber 18. These passages extend substantially the entire length of the furnace walls and upwardly to a point substantially midway between the floor 13 of the baking chamber 14 and the top wall of the furnace. At this point the furnace wallsare provided with ports or openings 37 to afford communication between -the respective chambers 36 and the baking cham her 145.. An additional series of ports or openings. 38 are also provided in each side wall of the furnace and afford communica tion between the chambers 36 and the other baking chamber 15.. A. damper plate 39, and 40 is, provided for each of the. ports 37 and 38 respectively. These damper plates, are mounted, for sliding movement in suitable guides 41v to each of the series of damper plates a rod 42 and 43 respectively is securedsaid rods at one of their ends being movable through, the front wall of the furnaqe structure and provided with suitable, hand holds. whereby they may be conveniently operated. The rear wall 22 of the ovenv proper is also provided with two. series of, ports, or open-ings ld and 45 respectively communicating with the respective ovenchambers 14: and 15 to admit the heated air I from the flue 21 intov the rear ends. of these chambers. These, two series of openings as well as the longitudinally extending series of openings 37 and 3.8 are preferably arranged in different vertical planes alternately with respect o ea h other,
From th above description, it will be readily understood that the heat and prodnets of combustion from; the. fire box 9, passng re r ardly through the chambers 11, causes the metal wal1 16 to, become very highly heated, the wall of the flue, 21 being ke-Wi heated in the upward passage of the products of combustion to the flue 24:, The heated, air radiates. through the. chamber 18, andv upwardly into the. chambers. 36 in the, side. walls. of the. furnace structure. If" both oven chambers are bein v used, the 013611859011 opens" both. series of dampers 39 and 4H1 through. the medium of the rods 42 and. easo'thatthe. hot air will be admitted in uniform volume into the two oven chambers at spaced points throughout the length thereof. This will result in the heating of these oven chambers to a substantially uniform temperature. While I have not herein illustrated damper plates for the openings 4A and 45 in the rear wall of the oven, it will be understood that if desired such damper plates may be provided. By means of my improved furnace structure,,it will be seen that the full heat, value of the smoke and products ofcombustionis utilized in the heating of the, oven chambers, while at the same, time all possibility of the smoke or gas, finding its way into the'baking chams0 bers of the. oven is obviated. The; h ating of these chambers can also be regulated and the chambers heated to the requisite degree, by the proper adjustment of the sliding damper plates.
From the foregoin description taken in connection with the, accompanying drawing, the construction, manner of operation and several advantages ofiny improved bakers furnace will be clearly and, fully understood. The invention provides a relatively simple and very substantial construction. for high capacity bakers ovens which'may be installed at relatively small cost and in the operation of which considerable economy may be realized in the consumption of'fuel. While. I have referred to but twobaking chambers, it is manifest of course, that a greater number of such chambers might, be employed as desired by an obvious extension 1 or duplication of the structure described. Theimproved furnace. is also, susceptible of a great many other modifications, in the form,
proportion and relative arrangement; of its several parts and it is therefore tobeunderw stood that I reserve the privilege of adopts ing all such legitimate changes as. may be fairly embodied within the spiritjand scope of the invention as claimed.
I claim V 1. In a furnace of the character described, a furnace stru ctu1'e.,, fire box extending substantially the entirelength thereof, a double chambered oven abovethe firebox andfa hot air chamber immediately below the oven, said furnace structure having spaced longitudinally extending passages communicating with the forward end of thefire bo Ytoconvey the smoke and productsfof combustion in contact with the wall of thehot air cham her to an outlet, and meansfor independently controlling the admission of; hothail, from said chamber into the respectivelovenchambers. i a r i p 2.
