UNITED STATES EDUARD A. C. PETERSEN,
OF LAKE VIEW, ILLINOIS,
BAKERS OVEN.
SPECIFICATION forming part of Letters Patent No. 400,250, dated March 26, 1889-.
' Application filed November 2'7, 1888. Serial No. 292,03 (No model.)
To all whom it may concern:
Be it known that I, EDUARD A. 0. PETER- SEN, a citizen of the United States of America, residing at Lake View, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bakers Ovens, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to the construction of bakers ovens, and more particularly to improvements on the oven described in the Letters Patent of the United States No. 363,416, granted to me on May 24, 1887.
The. object of my invention is to provide an air-flue in combination with the gas-flues of the furnace, to better regulate the. heat in the bottom of the oven, and also to connect with the oven a boiler for raising steam to be injected into the baking-chamber for producing a damp heat that will be advantageous to the bakings; and with these objects in view my invention consists of the novel'devices and combinations of devices herein after described and specifically claimed.
In the accompanying drawings, Figure 1 represents a longitudinal vertical section on line 1 1 in 2, and Fig. 2 is a vertical crosssection on line 2 2 in Fig. 1. Fig. 3 is a sectional plan on line 3 3 in Fig. 2, and Fig. 4 is a sectional plan on line 4 4: in Fig. 2.
Corresponding letters of reference in the several figures of the drawings designate like parts.
A denotes the fire-chamber, a the grate, and B the ash-pit.
b b are a series of flues, and b b are returnflues, all these flues being on the same plane parallel to each other and arranged underneath the hearth or baking-chamber, and the flues b and return-flues b communicate in the rear end through two chambers, o c. The return-flues b b communicate in the front end with vertical flues d d.
C is the hearth or baking-chamber, the bottom of which is heated from the gases passing through flues b and I); but because the heat radiated from flues Z), being much greater than the heat radiated from flues b, so much so that the bakings placed in the middle of the hearth over these flues I) would be scorched and charred, I have interposed between these flues Z) and the bottom of the hearth an air-flue, 01, divided from the flues b by an iron plate, 0, extending from the front of the oven the entire length of flues b, and in a manner that the rear end of air-flue n communicates with the chambers c c. The front end of this air-flue I provide with a sliding register, p, of any usual construction, for regulating the amount of air to be admitted for obtaining only the desired amount of heat at the bottom of the baking-chamber. The freshair thus admitted, in passing through this flue n, will absorb the heat from plate 0, so as to prevent the same from melting, and will convey the heat thus absorbed to the bot tom of the baking-chamber C, more or less, according to the quantity of air admitted, and will then enter chambers c, where the air thus heated will intermix with the gases issuing from flues Z), to produce perfect combustion of the same, and then the air and gases combined or the gases of combustion will con= tinue their course through return-flues b into vertical flues cl. The ceiling of the hearth chamber may be supported on iron T-bars, and underneath its ceiling are arranged longitudinally a series of iron pipe-flues, f and f, the flues f f communicating with the Vertical flues d d, and the return-flues ff communicating through chambers c with the flues f, and through a front vertical flue, g, with the longitudinal flues h h, that again through chambers i communicate with the return-flues h h. The flues h h lead into flue J, that forms the communicating-channel with the chimney D.
From each side of the fire-chamber A a transverse fiue, 7c, is provided with a trap-valve, Z, arranged to be operated by iron crank rods m, that are rigid with such valves and are projected through the front wall of the oven. By opening these valves Z the hot gases from the fire will follow the more direct course, and instead of first passing through the flues b b will be carried at once through flues d d to pipes f, which frequently will be desirable for small bakings that require more heat from above than from below.
F is a small boiler placed anywhere in front or rear, or, if necessary, to one side, of the oven, and communicating at top and bottom with theends of a water-circulating pipe, q, a U- bent portion of which is extended into any one flue, b or b, to be heated therein by the flowing gases, and thereby to heat the CIIGU- lating water and generate steam in such boiler F; and from the top of this boiler F a pipe, 0', is extended into the hearth or baking-chamber to exhaust the steam therein, the pipe 7* being provided with. a valve, .9, for regulating the amount of steam desired, as it may "ary with different kinds or sizes of bakin gs.
hat I claim is" 1.. In a bakers oven, direct and return gasflues below the hearth or baking-chamber and an air-flue interposed between the direct gasflues and hearth, with a register for regulating the amount of air to be admitted, substantially as and for the purpose set forth.
