The top direct opposition to each other in the bottom and marginal edge of the front and side walls are top walls respectively. bent at right angles to provide a rest for the Another object of the present invention is a table top 22 which is secured thereto by clips 37 means for directing all air drawn from the at to the front wall and by bolt and nut (not shown) mosphere over heating coils before circulatin to the side walls. The table top is provided with in the oven chamber proper. an upwardly extending back portion 39.
Another object is to provide in a range a drawer slidably mounted within the range 20 are a and an improved sliding arrangement therefor. plurality of drawers 40 which slide outwardly The invention itself, however, both as to its through openings 42 formed in the front wall 32. o a a n d it m d f p a t Each of the drawers is mounted on respective ugether with additional objects and advantages thereof, will best be understood from the following description of specific embodiments when read in conjunction with the accompanying drawings, in which:
Fig. 1 is a front elevational view of a range with parts broken away and embodying the present invention;
Fig, 2 is a cross sectional view taken along line 2-2 of Fig. 1;
Fig. 3 is a fragmentary cross sectional view taken along line 33 of Fig. 2;
Fig. 4 is a cross sectional view taken along line 44 of Fig. 1;
Fig. 5 is a cross sectional view taken along line 55 of Fig. 1;
Fig. 6 is a view with parts broken away and parts shown in section taken along line 6--6 of Fig. 5;
aioaee tical partitioned wall 16 and a horizontally ex tending partitioned Wall TI. The partitioned walls I6 and TI extend fromfront to rear wall of the range. An L-shaped member 19 is secured to the partitioned wall ll upon which is adapted to partially rest the oven liner 62. 1
The liner B2 is assembled into the rangeby insertion through the front wall opening l2. It is secured by bolts 95 having hooked ends 92 engaging over an edge of the rear Wall 5'! of the liner. The edge extends over the hollowed portion formed in the making of the shelf supports to permit engagement of the hooks over the overlapping edge. The opposite end of the bolts extend through the rear wall 34 for threading of a nut 93 to draw or pull the liner inwardly until the flange HI binds against the front wall 32. Preceding the binding of flange 79 against the front wall the section IIlI of gasket W9 is inserted to be clampingly held therebetween. The gasket is adapted to seal against the face of door II2 to prevent air entering into the oven chamber. The gasket is preferably formed in one length to extend peripherally to the door opening I82 immediately adjacent the top, and immediately adjacent the sides. The ends of the gasket are inserted into openings I63 in the front Wall to prevent fraying or unravelling of the end edges.
The gasket comprises cords M4 and i535 bound together in parallel relation by tape I86 whose ends are stitched together intermediate thecords I04 and I85 by thread 01. The cords I64 and WE are preferably formed of asbestoa'or Fiber- 1 glas, though other suitable high temperature insulation material may be used. The tape is preferably woven from Fiberglas, though it likewise may be formed of other suitable high temperature heat resisting material, or of 'ma- 5 terial to produce equal results which has been treated, or been suitably coated, to withstand high temperatures. The gasket after fabrication may if desired be suitably coated with high temperature heat resisting paint, ename1 or the like.
The cord I05 of the gasket is smaller in diameter to the cord IM to serve as the locking bead Illl when it is inserted between the flange l8 and front wall 32. The bead section I84 is adapted to extend peripherally adjacent the edge of v the flange Iii to seal against thedoor H2.
Oven door I I2 closing the opening IE2 is swingably mounted on pins H4 bearinged in lugs II B which project beyond the face of the front wall 32. The lugs H6 extend through openings in the front wall being attached to brackets ll! affixed to rear side of the front wall.
inserted the bottom edge of the inner door pan. The pans are then secured together adjacent the top by a Z-shaped bracket I26 which is secured to the outer pan by screws passing therethrough in securing the door handle I30 to the bracket. Screws I3I secure the inner pan to the bracket.
Recesses are formed in the door into which project the lugs IIB. Pivot pins II4 bearinged in the lugs II6 are secured to the inner pan by screws I34 which project through slots I35 formed in the inner pan to permit sliding adjustment of pin. Slots I3'I are cut in the bottom edge oflthe outer pan to permit access to the screws I34.
A gasket 0r seal I39 similar in construction -to described gasket I00 extends along the inner face of the door immediately adjacent its bottom edge. The gasket is secured by inserting the tail or looking bead section It)! between the flange I26 and the inner pan I26. The gasket is adapted to seal against the flange l9 imme diately adjacent the bottom of the opening Ifii. The gasket I39 sealing against the oven flange along the bottom of the door opening and the gasket I86 sealing against the face of the door along the other three sides, forms an air-tight seal around the door preventing air entering into the oven chamber or heated air in the oven escaping about the periphery of the door.
During the use of the oven, as for baking, a certain amount of air must be drawn into the oven to replace that drawn off in the venting of cooking steam or vapors. To control and direct the inlet of air of room temperature into the oven in manner so as to prevent cold areas in the oven chamber there is provided a passage I46 which communicates from the drawer compartment centrally into the oven chamber. The passage is provided with a lining I42, and positioned so that it is geometrically centered in the bottom Wall 65 of the oven. Air is drawn into the drawer compartment through opening I44 in the rear wall 34, and through opening I45 formed by insetting the front portion of the base member 35 from the front Wall 32. The bottom of the drawer 43 is perforated to permit free circulation of air upwardly from the floor to the passage I40.

The door II2 comprises an inner pan I25 and an outer pan I22 between which is packed suitsecured together by hanging upwardly the bot- Positioned over the passage I40 and resting on the bottom wall of the oven is an electrical heat- A bafile I52 is set directly over the heating coil sloped to direct the air upwardly towards the side walls of the oven chamber. The baflle also permitsthe heated air to pass forwardly to and upwardly along the face of the door and rearwardly to and upwardly along the rear wall of the oven chamber. The heating coil and'bafileare centered over the inlet passage hi6 so that a distribution of heated air is directed to all portions of the chamber, inthat the air must first pass over some portion of the heating coils I5!) before passing around the baffle to enter the oven chamber proper.
Directly over the inlet passage I40 in the top Wall of the oven chamber isa vent outlet I54 communicating with a laterally directed passage The passage I56 communicates with a vertical passage flue or chimney I which is opened at both ends to the atmosphere. The top outlet is throu h the grill opening IEO in the back 39 of 'thet'able top 22 The tom edge of the outer pan (see Fig. 7'), as at.
I26, forming a pocket or channel into which 'is passage I56 enters at an. intermediate point between the inlet and outlet ofthe passageway I50 so that as the air rises in the passageway or chimn'ey I59; it tends "to draw steam or vapors from the oven chamber through the passage I56. Entering the passage I50, from the passage I56, the steam or vapor mixes with the colder column of rising air to reduce its temperature before discharging through the grill opening I60 to the atmosphere.
A second heating element IE2 is suspended from hooks I65 from the top wall 56 of the oven liner. The element I82 is used for broiling and pre-heating of the oven. The lower element I50 is used for heating of the oven during the baking process. Both elements are connected to a manually set thermostatic switch I 01 mounted on the panel 2'1.
A suitable light bulb H0 is mounted in a glass front casing secured in an opening in the rear wall Bl of the oven chamber for illuminating the chamber. A suitable switch (not shown) operable by the opening and closing of the oven door is interposed in the electrical circuit to the light bulb to provide illumination when the door is in open position.
In the present arrangement the oven chamber is uniforml heated throughout. Cold areas are eliminated as all air drawn into the oven must flow across the heating coils before passing around the baffle and entering the baking or oven chamber proper. The air inlet being centrally positioned beneath the heating coils and bafile that the distribution of air is uniform to all parts of the oven chamber. By centrally locating the vent opening in opposed relation to the inlet Opening there is a uniform withdrawal of steam and vapors from the chamber. The possibilities of steam becoming entrapped in any portion of the chamber is reduced to a minimum and reducing the possibilities of any portion of the chamber becoming overheated. By evenly withdrawing the vapors from the oven chamber a uniform humidity is obtained throughout,
In Fig. there is shown a modified form of door construction wherein I80 is the outer front panel and I82 the rear panel. Panels I80 and I82 are secured together by U-shaped channel members I36 and screws I88. The channel member I 38 includes leg I which i secured to the side wall of panel I80, preferably in the same manner as panel I20 is secured to panel I22 as disclosed in Fig. 7. Screws I88 extend through channel member I86 and flange 202 of panel I82. Screws I88 also extend through gasket I00 and lock the gasket between flange 202 and member I86. The channel member I86 and gasket extend entirely about the periphery of the door forming a seal for the oven and thus dispensing with a gasket on the cabinet proper.
While I have described the preferred form of my invention, I do not wish to limit myself to the precise detail as shown but wish to avail myself of such variations and modifications as may come within the scope of the appended claim.
I claim:
In a range having an inner and an outer casing with heat insulation therebetween, said inner casing having side, top and bottom walls for forming an oven chamber, said inner casing forming an access opening to said chamber, a movable door for closing said opening, sealing means for sealing said door to said casings about said access opening, said oven bottom wall having an air intake passage disposed centrally thereof, an electrical heating element positioned over said passage and supported adjacent the bottom wall of said oven, a bafile positioned directly over said heating element and sloping upwardly toward the side walls of the oven chamber, said heating element and bafile being centered over said inlet passage so that a distribution of heated air is directed toward and upwardly along the face of said door and side walls, said oven top wall being provided with a vent outlet disposed in the central area thereof and a horizontally disposed heating element suspended from said oven top wall and coextensive with the major portion of the central area of the top wall.
