Specification of Letters Patent.

Patented Apr. 18, 1911.

Application filed May 22, 1908. Serial N 0. 434,355.

To all whom it may concern:

1% it known that I, FRANK L. GooDRIoH, a citizen of the United States, and a resident of Belvidere, in the county of Boone and State of Illinois, have invented certain new and useful Improvements in Ovens for Gas- Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a novel portable baking or roasting oven for gas stoves or tables, and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings :Figure 1 is a front elevation of a gas stove or table provided with an oven made in accordance with my invention. Fig. 2 is a top plan view of the oven. Fig. 3 is a horizontal section thereof. Fig. 4 is a vertical section of the oven, showing the stove in end elevation. Fig. 5 is a horizontal section, taken on line 55 of Fig. 4. Fig. 6 is a detail illustrating one construction for joining the oven frame to the oven base and for fixing the top plate of the base in position. Fig. 7 is a horizontal sect-ion of the parts shown in Fig. 6. Figs. 8 and 9 are views similar to Fig. 6 illustrating modifications. Figs. 10 and 11 are horizontal sections, respectively, of the constructions shown in Figs. 8 and 9.

The gas stove herein shown comprises a horizontal, rectangular frame or table 15 supported on legs 16 and provided with burners 17 of any preferred form located beneath the horizontal frame or table 15.

20 designates, as a whole, my improved oven and 21 designates an oven base which is removably mounted on the stove or table 15 and upon which the oven proper is removably supported. The said oven base is open at its lower side and rests at the lower margins of its walls on the top of the table 15 and incloses the usual supporting ribs 24. of said table on which are supported the articles to be heated when the stove is used without the oven. The oven frame proper may be made as an integral casting, and consists of a back wall 25, upper and lower rectangular frame members 26, 27, respectively, and upright posts 28, 29 joining the upper and lower rectangular frames; the posts 28 being located at the front of the oven and part of said base or the posts 29 being located at the rear of the I oven and made integral with the sides of the back wall, which latter is also integral with the rear members of the upper and lower frame members 26 and 27, respectively. The front and sides of the oven consist of swinging doors 30, 31, respectively, the latter of which are hinged by hinges 32, 32 to the rear posts 29, and the former of which is hinged by hinges 33 to one of the front posts 28. The top of the oven base comprises an inverted pyramidal plate 3 which is located at the upper side of said base 21 and may constitute an integral be detachably secured thereto. The top wall of the oven consists principally of a sheet glass panel 35 which is mounted in the upper rectangular frame member of the oven in the manner shown in Fig. 4 and which will be hereinafter described. The said top plate of the base is joined at its corners by arms 36 to the corners of the base 21 and is made of less horizontal dimensions than the like dimensions of the base, thereby providing spaces 37 between the margins of the top plate and said base to permit the heated air to pass upwardly from the base to the oven. The lower, rectangular frame member 27, of the oven is seated over the upper open side of the base 21 and rests on an exterior horizontal ledge 38 extending laterally from and made integral with the walls of said base. The lower margin of the lower frame member of the oven is turned inwardly to form a horizontal supporting flange 39 which rests on said ledge 38 and bears at its inner n1argin against an upwardly extending rim 4-0 of the base which rises above said ledge 38, lvgvhereby said oven is held centrally on the ase.

As shown in Figs. 5, 8 and 10, the connecting arms 36 of the base top plate are made integral with said top plate and also integral with the walls of the base. In the construction shown in Figs. 6, 7, 9 and 11, the said arms 36 are made integral with said top plate but are detachably connected with lugs 41 extending inwardly from the corners of the walls of the base by means of screw bolts 42. The said oven frame may rest upon and be held in place on said base by its own weight, being unattached thereto, as indicated in Figs. 5, 9 and 11. If desired, the oven may be attached to said base by means of a bolt 43 extending through the ledge 38 and through the horizontal flange 39 of the oven frame, as shown in Figs. 8 and 10. In a generally similar manner the oven may be attached to the base by lugs 45 (Figs. (3 and 7 which extend inwardly from the oven or upper margin of the base walls and over the lugs 41, and may be attached to said latter lugs by the same bolts 42 which connect-thearms 36 of the base top plate with said lugs 41.

The side and front doors 30 and 31, 31, respectively, each consist of'a complete surroundingmetal frame,'having top and bottom members 55, 55 and side members 56, 57, and atdepressed panel of sheet glass 58, which latter constitutes the principal portionuofthe door. Thesaidglass panels of the doors and also the top wall are attached attheir margins to the door frames and upper. frame member, respectively, by yielding connections which permit differential expansion of the glass-and metal without injury to the former. panels-to the door frames and the top frame member ofthe oven to produce the resultis herein shown asmade as follows :-The said glass panels fit at their margins in rabbets 59, formed on the inner marginal portions ofthe members of the frames. in which they are h eld,.-and said panels are made of less dimensions than the rabbeted portion-s of. the

also provided at their free marginswith.

latches-66a which extend endwise therefrom forengagement with notched lugs 67 formed on or fixed to the door frame or .post, and by which said doors are held closed. The said oven .is provided interiorly with a plurality of horizontal shelves 68,- 68 which aresupported attheir side margins on ledges G9, 69.- formed onthe inner sides of the front andv rear posts 28 and 29, respectively, said shelves being adapted to be inserted into the oven through the front openingl thereof when the .front door. 30 is open. The front wall of the base21 is provided with an openingz'ZO, .closedby a door 71, through which.

may be inserted a taper or torchto light the burner or burners beneath the base.

The exterior surface of the Walls; of the. oven are coated with a heavy coat of enamel.

72to give the same a neat and attractive appearance, and also to prevent the oven be- The attachment of the glass.-

coming greasy and grimy. The enamel employed 18 of a v1treouscharacter which is applied in a plastic state and is fixed by ,heat,and produces a surface which is smooth .and exceedingly hard. The inner surfaces of the metal parts of the oven walls may, for a l1ke reason, be covered with a coat of like enamel 7 An oven made in accordance with my invention presents a very neat and attractive appearance andmay be kept in a sanitary condition at the expense-of little time and labor. The provision of the. two side and front swingingdoors isadvantageous, inasmuchas this construction affords easy-"and ready access to all parts of the oven for the purpose of inserting or removing articles therefrom and enables the interior of the oven :to. be fully exposed for the purpose-of cleaning and ventilatingthe same: Furthermore, the provision of thethree: doors,--.whiclf permits access. to -the oven fronrithree sides thereof, enables said oven"loca-* tions where; convenient. access. could not be had toan ovenhaving-a single door, as, .for instance, in locations where 2 access: may 1 be cut off from one or more sides of the oven by an adj acent wall, articletof furniture or.

thelike. The use ofglasspa-nels in the doors and the top wall; isadvantageous inasmuch as it permits theoperationof the oven to be fully observed while the :ovenis, closed, thus avoiding the necessity of admittingcoolair or drafts to the event when; the. contents thereof are tobe. inspected. Moreover, the use .of the glass panels applied as described adds greatly to the. attractiveness of'the.

oven- The base -21 may be formedatthe. lower margins of itswalls to. fit over. and inclose differentstyles ori types .of ga's.stovesor. tablesin connection with which the oven? is to be used, and will beeformed at its-upper side. to receive and support oven= frames which roughly 7 adhere to general standards of diniensionsand shapes ofovens. That isto say, the sa1d base-21-constitutes a connection that may adapt vstandardovensofithe.

character. described to gas stoves or tables varying somewhat in their dimensionsand contour.. Thus, for different designs of .gas; stoves, various designs.- of the base 21 may beiemployed to support ovens of standard sizes and shapes.

Structural changes may be made i without departure from the, spirit .of myinvention and I do notwishto be limitedto tails except as hereinafter. made the. subjectof specific claims.

Iclaim as my invention 1. A- portable oven for gas stoves. and tables provided. with abase adapted torest on and be. supported .by agas stove: or. table, said 'ov-en-comprisinga frame consisting, of aback wall, upper and lower horizontal, open as frame members, and corner posts connecting f on the side walls of the base and arranged to said upper and. lower frame members, the I provide between its margins and said walls lower frame member being detachably fitted of the base spaces for the passage of heated to said base and the top wall of the oven be I air from the base to the oven, said oven ing supported by the upper frame member, being provided in its wall with an opening, and front and side swinging doors hinged to and a swinging door for closing said opensaid posts to constitute the side and front ing. walls of the oven.
