COOKING STOVE.

Application filed December 9, 1926. Serial No. 153,496.

oven door, also having a cast metal frame, is

arranged to seat.

One object of the present invention is to eliminate the cast front frame for the oven,

so as to reduce the cost of manufacture.

Prior structures have also been objectionable in that the seams and joints between the usual oven section and the oven door frame have a tendency to catch and accumulate dirt, and the same is true of the hinged mounting of the oven door upon the frame. It is therefore another object of this invention to provide'an improved stove construction in which the joints incident to the mounting of the oven door frame on the stove are substantially eliminated, and in which the hinges for pivotally supporting the door are entirely concealed when the door is closed.

A general object is to provide an improved stove construction in which a cheap, simple and sturdy construction coupled with a neat appearance and an easily cleaned structure are salient features.

Other objects and advantages will become apparent in the description and from the drawings, in which I Figure 1 is a front elevation of a stove showing the preferred form of this invention.

Figs. 2 and 3 are fragmentary side elevations showing the door in closed and open positions, Fig. 2 bein partially broken away to show the preferred hingeconstruction.

Fig. 4 is a section taken on a line 1-41 of Fig. 1.

For the purpose of disclosure I have chosen to portray the preferred form of the invention as embodied in a gas cook stove comprising a base or oven section 5 and a top 6 mounted on the base as by brackets 7 from each upper corner thereof, said base being supported from the floor by suitable legs 8.

The oven comprises generally a pair of side walls 9, a rear wall 10, a top 11 and a bottom 12 of sheet metal construction. In attaining the objects of this invention I have provided an oven door frame integral with the oven by turning the front edges of the sheet metal side walls 9 and the top 11 inwardly at substantially right angles to'provide frame flanges 13 and 14. If desired the edges of the frame thus formed may be turned inwardly pro- ,viding a strengthening flange 15.

A front plate 16 preferably formed of cast metal is rigidly secured across the lower portion ofthe base 5 to provide a'false base generally designated as 17. The upper edge of the plate 16 is preferably curled inwardly and downwardly to provide a rounded upper surface '(Figs. 2 and 3). A false bottom 18 is secured within the oven substantially flush with the upper rounded edge of the front plate 16.

A door, having any suitable construction, such as a cast door frame 19 and a panel plate .20 therein, is arranged normally to rest upon the rounded upper edge of the front plate 16. The sizeand design of the door is such that the door, when closed, entirely conceals the oven opening and frame. A suitable handle 31 may be secured upon the upper edge of said oor.

A pair of bent arms or levers 22 each having a recess '23 in the under side thereof are rigidly secured on the lower part of the door frame 19 near the ends thereof in such manner that when the door is in normal closed position on the stove the lever will extend inwardly and downwardly of the base. On each side of the oven both the side frame flanges 13 and the false bottom 18 are slotted,

as at 24, to permit swinging movement of the levers theret-hrough when the door is mounted. The lower ends of these slots, it will be observed, are closed by the front plate.

When the door is swung open, the bottom of the door moves away from the supporting edge of the plate 16, the recesses 23 on the levers 22 bearing on the rounded edge of the plate as a fulcrum thereby supporting the door. Heads 25 suitably positioned on the levers 22 are arranged to contact the frame members 13 at the horizontal or open position of the door and hold the door against further movement in that direction. These heads also are adapted to interengage with the curledupper edge of the front plate in the closed position of the door, and since the slots through which the levers extend are closed at their lower ends by the front plate, it will be seen that the fastening in place of the front the stove at any position of the door. In the present instance this means comprises a resilient member such as the helical spring 26 anchored to a pin 27 or the like, secured upon the inner side of the front plate 16. A flexible member, such as a chain 28, passes around a guide pulley 29 suitably mounted beneath the false bottom at a point underlying one of the levers 22, and is connected at one end to the spring 26 and at the other end to one of the hinge levers 22. Thus a counterbalance is provided acting against the weight of the door during opening and closing and exerting an eflective downward pull at both positions to hold the door firmly seated upon the plate 16.

It will be readily seen that a construction of a stove has been provided in which the front frame is formed of sheet metal integrally with the oven, thus reducing the cost of manfacture and eliminating the joints usually incident to the interfitting door and oven frame construction.

ll claim as my invention:

1. A stove comprising, in combination, a cooking top, a base section formed of sheet metal to provide top, bottom, side and rear walls with inturned flanges at the forward edges of the side and top walls defining a frame, brackets at the front and rear corners of the base section and secured thereto to support the top, a front plate extending across the lower portion of the base section, said plate being formed of cast metal and shaped to provide a rounded upper edge, a false bottom in said base section substantially in the plane of'the upper edge of said plate, and a door having a pair of supporting arms upon its inner side adapted to turn upon the upper edge of said plate, said door being of a width substantially equal to the width of the oven section, and said front plate being of a thickness at its upper edge substantially equal to the thickness of the door.

2. A stove comprising, in combination, a cooking top, a base section formed of sheet metal to provide top, bottom, side and rear 7 walls with inturned flanges at the forward edges of the side and top walls defining a frame, a front plate extending across the lower portion of the base section, said plate being formed of cast metal and shaped to provide a rounded upper edge, a false bottom in said base section substantially in the plane of the upper edge of said plate, and a door hinged upon said front plate and arranged to overlap the sheet metal oven frame.
