To llwhom't may concern:

Be it hnown that ll, BENJAMIN lE. lli/lneyoi-iAM, Va citizen of the lUnited States, resid-` ing at Lorain, in the county of Lorain and State of Uhio, have invented certain new and useful Improvements in Uvens, of which the following is a specication, reference being had therein to the accompanying drawing. l

This invention relates tov improvements in ovens, and more. particularly to an improved oven construction in which thevheating element is a gas burner. My improved oven is designed tor use in domestic science schools, where the-use to which it is put makes it desirable to have a number ol small ovens operatingat the same l -i time, each individual oven being used by one oitithe pupils. v

'ln my improved construction each of the individual ovens is contained in the one umain oven and'all of the ovens 'are in communication. llhe heat in the oven will be controlled by a regulator, such as is de scribed in my Patent No. 1,334,776 ot March 23rd, 1920, or a rthe' regulator will be placed in the large oven and will control and regulate the' heat tor the several smaller ovens therein.

'lo maintain an even temperature in an oven ot such large proportions where the heat is provided by a single burner and regulated by a sin le tuel controhthere must be a tree circulation ot heat. 'l`he tuel ventilation must beproperly located and'ot the right proportion, and the regulator is a very important taeter as it controls the fuel supbld ply iii such a manner as not to cause excessive heat currents in certain parts oit the oven, which would malte 4uneven temperatures unless 'the tire is properly controlled by the regulator.

- '.l`o accomplish these ends and improved results, ll have constructed my oven, burner and regulator in a manner hereinatter described.

Ylhe primary object ot my invention is to provide a main oven. which contains a plurality ot smaller supplemental ovens, wherein the heatcan be regulated and controlled to a desired temperature.. v

V

rlhe main 4oven is preterably oblong in shape, although the shape may be altered as desired, and consists oit the bottom l, the end walls a and 3the hack t, the tront ti and the top 6. The to bottoni, trent and sidesare preferably o' dat-sheet metal. as shown, and are spot welded as at 7, or othern wise suitably fastened in the trame',y which ismade preterably oit channel iron,- and t C, the heat and individual ovensand the oven-'traine (E, a

which sup corner uprights 8, which are elongated to form legs carrying the foot members 9, rt the oven above the floor 10. As clear y appears in Figs-2, 3 and 4 of the drawings, the oven is provided with an lnner supplemental back 11, which extends the entire height -of the oven and' ,forms a H ue 12, having an open bottom 13 and an opening 14, through the top 6 of the oven .intopthe iue collar 15.

` drawings, the front plate '5 of the oven is provided with a plurality ofoven openings 17, and it is into these openings that the supplemental ovens or racks are placed.

Thev racks B consists of the horizontal frame members 18, preferably of angle iron, which carry at their outer ends the doorframe 19. The door-frame 19 is spot welded, as .at 20, or otherwise fastened to the rack members 18, and the outer faces 21 of the door frame extend outwardly to overlap the vfront 5 of the oven, as at 22, and are bolted as at 23, or otherwise suitably fastened to-the front 5 of the oven. lThe bolts 23 holding vthe door-frame 19 to the front of the oven are the only supports for the oven rack B, and the horizontal members 18 of the racks B are held in alignment and there properly positioned by means .of the bands 24. The oven rack B is further provided with the horizontal. U- shaped grill supports 25, for receiving the oven grills 26, which slide in and out upon these grill supports.

The face 21 of the door-frame 19 is provided with the outstanding lugs 27 having openings 28 which receive and support in hinged relation the doors 30, by means of `pins 29 and the lugs 31, which are. carried by the door. The supplementaloven doors 30 are provided with the usual handles or knobs 32 and the doors with the glass 30*l to allow vision into the oven.

As clearl appears in the drawings, the main oven carries six of the supplemental oven racks B, the oven racks beingposi-l tioned two deep across the oven and comprise three tiers. It will, of course, be readily understood that the number of supplev mental ovens can be varied to meet the desired use.

Bel-ow the bottom tier of the supplemental ovens B, is the burner space 33, in ,which the burner C extends across the back, sides and the front of the oven with the exception of the small space 34, where the ends 35 and 36 of the burner are in separated relation. The burner C is provided with burner openings 37, these burner openings `being only .in the front and side portions of the burner, as shown` in Figure 3 of the drawings.'

' Supported on the front corner uprights or legs 8 of the oven A, by means of the brackets 38,- or in some other suitable manner, is'the gas supplyconduit 39, which is in communication with a gas supply (not shown) and midway the length of the gas supply conduit 39 is avalve coupling 40 carrying the usual valve controlling handle 41. Connected to and supported above the valve coupling 40 is the heat and fuel regulator D. In communication with the lower portion of the heatand fuel regulator D is an air-mixer 42, which in turn is 1n coinmunication with the gas ipe 43, which is in communication with tieV gas burner C, through the medium of the T-joint 44 or lsome other connection.

The upper end of the heat and fuel regulator D carries the inwardly extending thermostatic tube 45, which is in a position be` tween the vertical tiers of supplemental oven members B, as clearly appears in the drawings. The heat and fuel regulator D carries a regulator wheel 46 for seating the thermostatic fuel and heat regulator to the desired adjustment for regulating the heat to the desired degree. I am not describing the mechanism of the( regulator D in particular, as this mechanism is covered by several patents granted to me, one of which is Patent No. 1,334,776, of March 23rd, 1920, and this thermostatic control could be constructed along the lines of any tliermostatic control as known in the art.

Although I have described the burner C as a continuous burner encircling the. bottom of the stove, with the exception of the small space 34, it will be readily understood that the burner could be constructed in two Ushaped pieces, one end of the U-sliaped pieces being connected by the T-joint 44, and the other end of the pieces being separated by the space 34.

' The front 5 of the oven is provided with two observation openings 47, for observing the burner, and thesejopenings are covered by the doors 48'pivoted as. at 49.

As heretofore pointed out, to maintain an even temperature in an oven of such large proportions, with one burner and one fuel control,.there must be a free circulation of heat and', therefore, the flue ventilation must be properly located and of the right proportion.

I To provide for this air circulation, I have first, as has been described, constructed the supplemental oven frames B of open construction and entirely supported from the front of the oven. To support the supplemental ovens from the oven walls or back would tend to obstruct' the free passage of air in the main oven. In the bottom l of Gill ntf-insee ythe main oven l have provided the air openings 16 which are below the oven burner C .throughout all of its portion which is provided with the burner openings 37. rlbe flue 12 of the oven has a free passage of air throughout its length, due to its open bottom 13`and its top opening 14, into the ue collar 15. To provide circulation of air and heat from the main oven into the oven flue, l have provided a series of openings 50, and these openings are graduated as to numbers, as clearly appears in Fig. 6, and are in separated parallel relation.

The oven grills 26, vwhich slide in the supplemental ovens B as described, provide a means forisupporting the food which will be put into the supplemental ovens for cooking. ll have further provided two perforated plates 51, which will be supported and carried by the two lower supplemental ovens B, just above the oven burner C, as shown in Fig'. 2 of the drawings. rllhese perforated plates 51 are used for the purpose of causing an even distribution of heat. The heat travels to a. certain extent through these preforated plates, but the greater part of the heat will rise upwardly through the space 52 at the edges of the plates and the supplemental oven racks B.

From the foregoing it will be seen that ll have provided an oven in which there is a plurality of supplemental ovens or oven 'racks for individual or sepa-rate use, in which the heatl lis provided by a single burner, the burner supplied by a single airmixer and the heat and fuel controlled by a single automatic regulator,

rllthough .l have not described in particular the heat regulator l), it will be understood that the regulator will be constructed in such a manner that when the regulator wheel 46 thereof is set at a predetermined temperature, the regulator l) will maintain thisl temperature in the main oven l by controlling the gas feed to the oven burner C.
