The topeplate 7 is substantially rectanguhit in form having a-Fdepending flange:18 at its edges. Usua llyr in applian-ces o f this type two burners areprovided, and herein II?

Otherwise; the itopl plate foams a closed upper Wall for the burner chamber or housing.

The end plates 9' are): rigidly secured at their. upper edges to the underside of top plate -7 'nearfthe'opposite ends thereof. The" means for, thus securing' these parts together preferably; comprise] outwardly projecting biturcated-.- lugs 2() adapted to engage ati theirfree ends 1 the underside 1 of; the a top:

This facilitates the assembling of the parts since it renders it-unnecessary to hold the nut by means of a tool while the bolt is being turned.

The means thus provided for fastening the end plates to the top plate has been found to be exceedingly effectual, serving rigidly to hold the parts in proper relation.

The means for effecting the interengagement between the front and rear plates and 11, the top plate ,7, and the end plates 9, so as to hold said front and rear plates in position between the end plates, will now be described,

Projecting from the underside of the top plate near the front and rear thereof is a series of lugs for holding the front and

rear plates

10 and 11 against lateral movement. -The lugs 25 are staggered so that the alternate lugs bear against opposite sides of the front and rear plates when the latter are pressed against the top plate. The vertical ends of each front plate 10 or rear plate 11 are wedged between an inwardly extending flange 26 on each end plate 9 and a curved shoulder 22 formed on the outer side of the lug 22. It will be remembered that the lugs 22 project from the end plate 9 and assist in securing the latter to the top plate 7. Thus, in the present instance, the upper end and the vertical edges of the front and

rear plates

10 and 11 are held between two opposed surfaces, an outer surface formed by the flange 26 and the outermost lugs 25, and an inner surface formed by the innermost lugs 25 and the shoulder 22.

The lower edge of the front plate is supported in sockets 27 formed upon the inner sides of the end plates 9 as continuations of the flanges 26 (Fig. 3) and the lower edges of'the rear plate 11 are supported upon horizontal ledges 28 and between vertical flanges 29 on said ledges and the flange 26, said ledges and flanges being formed upon the inner side of each of the plates 9. Preferably the front and rear plates are constructed of sheet metal of relatively light guage, the lower edge of the front plate being beaded so as to enclose a reinforcing rod 10*, and the lower edge of the rear plate being provided with an inturned flange 30 adapted to engage in the socket provided by the ledges 28 and the

flanges

26 and 29.

To receive the drip pan 12 the front plate 10 terminates at short distance above the lower edges of the end plates 9, and the latter are provided at a spaced interval below the sockets 27 with horizontal ledges 31 forming supports upon which the drip pan may slide. The flange 29 atthe rear edges of the plates 9 constitutes stops for limiting the rearward or inward movement 0f the drip pan (Fig. 3). For supporting the appliance in slightly elevated position, the end plates are provided with feet 32 formed integral therewith.

The gas burners 13 may be of any suitable or preferred construction, adapted to engage with the supporting rod 141-. The opposite ends of the latter are entered in sockets 33 formed upon the inner sides of the end plates a short distance below their centers.

The gas manifold 15 is in the form of a pipe closed at one end and open at its opposite end so as to be adapted for connection with a suitable source of gas supply. The brackets-16 for supporting this pipe may be of any preferred construction, being herein shown as formed of sheet metal and sesured at their upper rear ends to the underside of the top plate near its forward edge.

To this end each of said brackets is provided In order to receive the forward end por- 7 tion of the burner 13, and also provide for the admission of air to the burner chamber, the front plate 10 is provided with apertures 37.

It will be observed that-the construction which I have provided is extremely simple,

enabling the construction of the parts at a relatively low cost as well as their rapid assembling. By the provision of a chamber or housing for the burners, the efliciency of the appliance 15 increased through the con-.

centration of the heat upon the cooking utensils supported upon the grids. over, the enclosed chamber for the burners renders it possible to use the hot plate outof-doors where the ordinary construction is incapable of use because of excessive drafts. Finally, the appearance of the appliance is improved by reason of the fact that the housing serves to conceal the unsightly burners from view.

I claim as my invention:

1. A hot plate comprising a rigid top frame provided with one or more grid openings, a pair of rigid. end plates, means for detachably securing the end plates to the under side of the top plate at opposite ends of the latter, said end plates constituting cured t0 the top plate, said rear plate and More-- the two end plates coacting with the top plate to provide a burner chamber.

2. A hot plate comprising, in combination, a rigid top frame provided with one or more grid openings, a pair of rigid end frames bolted to the under side of the top frame at opposite ends thereof and constituting supports for the top frame, and front and rear plates interposed between said end frames beneath the top frame and interengaging with said frames so as to be held in position by the end frames when the latter are secured to the top frame.

3. A hot plate comprising, in combination, a rigid top frame provided with one or more grid openings, a pair of rigid end frames bolted to the under side of the top frame at opposite ends thereof and constituting supports for the top frame, front and rear plates interposed between said end frames beneath the top frame and interengaging with said frames so as to be held in position by the end frames when the latter are secured to the top frame, and a drip pan supported at its opposite ends by said end frames for sliding movement in a front to rear direction, the front plate having its lower end terminating above said drip pan to permit such sliding movement of the latter.

In testimony whereof, I have hereunto afiixed my signature.
