Application filed October 20. 1905- Serial No. 283,591.

To all whom it may concern.-

Be it known that I, GEORGE R. MOON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ovens, of which the following is a specification.

My invention relates to new and useful improvements in ovens.

The object of the invention is to provide within the oven a spreading or deflecting drum into which air is admit-ted from the exterior of the casing. This drum serves two purposes-that of supplying air to the urners for properly supporting combustion and preventing overheating of the lower part of the heating-compartment.

Still another feature resides in the arran ernent and construction of the parts where y the distribution of the heat products is equalized and the said products fully deprived of their heat before escaping from the oven.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, and eflicient and simple and comparatively'inexpensive to produce.

With the above and other objects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the accompanying drawings, wherein- Figure 1 is a lon itudinal vertical sectional view taken on the line a: w of Fig. .2. Fig. 2 is a transverse vertical sectional view taken on the line '31 y of Fig. 1. Fig. 3 is a horizontal cross-sectional view taken on the line aa of Fig. 1, and Fi 4 is a transverse vertical sectional view talien on the line b b of Fig. 1.

In the drawings, the numeral 1 designates the casing of the oven, which is substantially rectangular in cross-section and constructed of any suitable sheet metal. At the central portion of its to i an outlet or escape opening 2 is provided. home distance above the bottom of the oven an air-drum 3, trian uler in crossseotion, is arranged, extending ongitudinall; of the oven between the end walls thereof. The drum is secure-Iv fixed in place and at each end is provided with airinlvt l'rl'lcnings 4, which communicate and register with air-openings 5, formed in the end walls. The apex of the drum, which isdirern-d downward, is |')'l'ovidv(l with a plurality of mfwnlllgs 0, through which the mr admiIu-d by the openings 4 and 5 is ejected. Slightly below the drum and on each side of the apex thereof parallel gas-burners 7 are provided. By provision of the air-drum 3 a sufiicient quantity of air is supplied to the burners to properly support combustion, while at the same time the upwardly-inclined sides of the drum act to spread or deflect the heat products from the burners, so as to cause an equal dis tribution of the same, as will be hereinafter described. The upper side of the drum 3, which is fiat, supports and forms the bottom of a heating-compartment A, at the front of which the oven is provided with an openin 8, covered b r a suitable door or closure 9. he sides of t e compartment A are formed by vertical side or end plates 10, which extend entirely from thefront to the back of the oven and are covered by a to plate 11, extending in a like manner. The ack of the com artment is formed by a vertical plate or we 12, which extends upwardly from the drum 3, but terminates short of the under side of the top plate 11, so as to provide an inlet-opening 13. The compartment A is divided into two cells by means of a shelf or horizontal plate 14, which terminates short of the front wall of the oven, so as to rovide communication between the two cel s. Outlet-o enings 15 and 16 are provided in the end Wa s 10 of the compartment, the openings 15 being positioned near the forward end of the upper cell and the openings 16 arranged near the rear end of the lower cell. These openings provide for the escape of the products from the cells after the some have assed there thron -h. The end or side wal s 10 provide with are end or side walls of the oven-casing vertical lines B, which terminate at their u per end in a horizontal flue or chamber formed by the top plate 11 and the top oi the oven-casing, while the wall or plate 12 of the compartment A forms with the rear or back wall of the oven-casing a vertical heat-conducting line D, said flue being closed at its upper end by the plate 11, but having commul'licntion through the opening 13 with the up no cell of the compartment.

deferring to Fig. 2, it will be obvious that the heat prmlucts generated by the righthund humor 7 will be directed by the drum 3 lulu lluvertical hml-l-romlurting llnc l). ,up which they will puss through the opening 13 into the upper cell of the mnnpnrtnwm. A, while the heal products generated by the burner 7 on the left-hum! side of the drum will be duller-ted and directed by tho some as to pass up into the lower cell of t-hc com- )artment A, circulating therein and fully eating the same. The heat products passing to the rear of the lower cell will escaple throu h the opening 16 into the side Hues (see Figs. 1 and 2,) while the products at the forward end of the said lower cell will pass up around the 'frontedge of the shelf 14 into the upper oell,wherc the) willcirculote and mingle with the roducts entering through the opening 13, al the products finally passing out through the openings 15 into the vertlcul flues B,where mixing with the products from the openings 16 they will ass upward Into the horizontal fiue (J and nail escape through the opening 2.-

It will be apparent that by dehverm a greater amount of heat to the upper col of the compartment and by provision of the cold-air drum 3 at the bottom of the lower cell the compartments are equally heated and the heatso regulated that one cell receives comparatively the same amount as the other.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An oven comprising an outer casing, a drum extending from end to end of said easingand having ontlet-openin s at the bottom thereof, gas-burners arranged upon each side of said outlet-openings, and a boking-chumher located above said drum, the interior of said drum being in communication with the ntmospllllere.

oven comprising an outer casing, a drum extending from end to end of said casing, said drum beinq triangular in cross-section and forming inclined side walls, the interior of said drum being in communication with the atmosphere and with the interior of the outer casing through openings formed at the lower so '5 portion of said drum, gas-burners arrz'inged adjacent said drum upon each side of said o )enings, and a bakingchamber located a IOVt' said drum.

3. Au oven comprising an outer casing. a. drum extending lengthwise of said casing, the interior of said drum being in comn'iunication with the atmosphere and said drum having air-outlet. openings at its bottom, gas-burners arranged adjacent said outlet-openings, a baking-chamber located above said drum, means for conducting the heat from one of said gas-burners to the upper portion of the baking-chamber, means for conducting the heat from the other of said gas-burners to the lower portion of the baking-chamber, and means for permit ting the passage of heat from the upper and lower portions of the bakingchomber to the interior of the. outer easing.

4. An oven eomprisin an outer casing,

artitions located in said outer casing and Forming a bakingrhamber, said partitions comprising two sidewalls, a top wall and a rear wall which terminates short of the top wall, a deflectingdmm which forms the bottom of the oven, the interior of said drum being in communication with the atmosphereond said drum having oiroutlet openings in its lower portion, burners arranged u 101] each side of sold outlet-openings and sai deflectlug-drum being ndated to direct the products of combustion iiom one of said burners to a passage formed between the rear wall of the bakin -chamber and the outer casing and to direct 51c products of combustion from the other of said burners to the lower portion of the baking-chamber.

In testimony whereof I aliix my signature in presence of two witnesses.
