SAFETY PLATE TO PREVENT GAS BURNERS FROM BEING EXTINGUISHED Filed May 20, 1952 INVENTOR.

Patented Oct. 31, 1933 PATENT OFFICE SAFETY PLATE TO PREVENT GAS 'BURNERS FROM BEING EXTINGUISHED Henry Gersh, Bronx, N. Y. Application May 20, 1932. Serial No. 612,407

6 Claims. (01. 126-214) This invention relates to improvements in means for protecting the burners of gas stoves from the overflow of boiling pots and cooking vessels, and its leading object is to provide a safety protecting plate which can be placed over a gas burner, and which will allow the heated air to flow upwardly, and cause the water which boils over to drain away from the flame jet openings of the gas burner.

Another object of the invention is the provision of a safety protecting plate for gas burners, which will concentratethe flow of the water discharged from a cooking vessel when it boils over, toward the center of the gas burner and por- 15. tions of its radial wings, so as to direct the drainage away from the jet openings of the gas burner, so as to prevent the water from the boiling cooking vessel from extinguishing the burner-flame. t

A still further object of the invention is to provide a top plate for gasstoves, which will provide complete safety against the accidental extinguishing of the burner flames by the water which boils over from cooking vessels, and which can be placed in position by any housewife 01' other person.

With the above and other objects in view the invention consists in certain new and useful combinations, constructions, and arrangements of parts, clearly described in the following speciflcation, and fully illustrated in the accompanying drawing, in which:- 7

Fig. 1 is a plan view of the improved safety plate.

Fig. 2 is a transverse sectional view thereof, taken on line A of Fig. 1, looking in the direction of the arrow,

Fig. 3 is a plan View of a stove plate embodying a plurality of sections each having the pro- 40 tective features.

Referring to the accompanying drawing illustrating the practical construction of the invention 5 designates a circular plate, which may be constructed of stamped sheet metal, or cast in one piece from suitable heat resisting metal. When made from sheet metal the plate is preferably formed with a U-shaped rolled edge portion 6, which presents an upstanding marginal flow limiting rim, and an annular depending skirt 6a, which is wider than the marginal flow limiting rim 7.

The plate is slightly dished from this marginal flow limiting rim '7 toward the center thereof, and the center is formed with a depending tubular outlet 8, which is designed to receive the overflow water discharged by the cooking vessel, which is placed overthe plate and within the marginal rim 7. 1

The plate is formed with radial openings or slots 9, spaced circumferentially from each other, and the marginal edges of these radial openings are provided with upstanding flanges 9a, of slightly less height than the marginal rim 7. The openings are shown triangular in form, but any other desirable shape may be used.

outwardly of the radial openings'and their flanges arcuate vessel supporting flanges or beaded portions 10 are formed, the opposing ends 'of which are spaced apart to allow nor- '(0 mally open drain channels 10a, to permit the overflow water to flow between the flanges 9a and discharge through the central outlet tube 8, and to discharge over the gas burner, at a point safely remote from the jet openings of the burner, from which the gas flames are fed. The radial imperforate portions 9" are designed to register at the radial flanges of a standard gas burner, which are thereby protected from filling up from the drippings of grease or carbon particles deposited from the bottom of pots or other cooking vessels, while the radial openings 9 are designed to register with the spaces between the radial flanges of a standard gas burner, thus permitting a free circulation of heated air from the gas burner under the pot. The central openingoutlet 8 is adapted to register with the central opening of a standard gas burner and thereby centers the safety plate with reference to the gas burner.

The upstanding circumferential flanges 10 support the pot upon the flanges 9a, so that the heated air flowing over the gas burner can flow through the openings 9 and through the channels 10a to discharge outwardly of the sides of the pot as indicated in Fig. 2. 'By this construction the safety device provides for ample circulation of the heated air and at the same time afiords a centralized drainage of any overflow from the pot, while at the same time maintaining lOO a separate path for the flow of the heated air at any time during an overflowing movement. This effect develops from the fact that the overflowing water will drain on the inclined surface of the plate and the heated air can discharge above 105 the surface of the water through the openings 9 and the channels 10a.

In Fig. 3 I show a stove plate or covering 11, which is formed with three integral safety protecting plates, 12, 13, and 14, each embodying l10 the principles of construction shown in Figs. 1 and 2.

This combined stove plate and burner protecting device may be attached to gas stoves at the factories where they are made, or may be attached by the individual user. The combined stove plate and burner protecting device may be constructed with two, three, four or more protecting plates in any arrangement desired to match the burner assembly of a gas stove.

In the use of the safety plate a slight overflow will drain through the channels or passages 10a into the central outlet 8, while a greater overflow will pass over the flanges 9a into the openings 9, and discharge over the gas burner,. away from the jet openings thereof.

The openings 9 may be arranged according to any desired plan, to match the radial. dis-.7

position of the flanges of any particular gas burner, so thatthe said openings 9 will be opposite the space between adjacent burner flanges, while the imperforate portions 9' be tween said openings 9 will lie opposite the flanges of the gas burner.

The cover top 11 is also formed with arcuate openings 15, located outwardly of the safety portions thereof, and adjacent thereto, to permit the heated air to flow upwardly, so that fresh air will flow toward the burners and efficient heating of anycooking vessels disposed on the improved stove cover or top will result.

Having described my invention I claim:-

1. A safety plate for gas burners consisting of a plate adapted to cover a gas burner and provided with an inclined draining surface surrounded by a flow limiting element and discharging into a drain outlet and provided with radial openings spaced to; register with the spaces between the flanges of thegas burner.

2. A safety plate for gas burners consisting of a plate adapted to cover a gas burner and provided with a central discharge outlet and a draining surface extending outwardly thereof and formed with a flow limiting rim, the plate being provided with flow discharge means located outwardly of the central outlet and further provided with radial openings arranged to register with the spaces between the flanges of a standard radial flanged gas burner.

3. A safety plate for gas burners consisting of a plate forming a covering for a gas burner and provided with an upstanding flow limiting rim within which a cooking vessel may be disposed and also provided with means for supporting the bottom of the cooking vessel above the upper surface of the plate, the plate being formed with a drain outlet and having an inclination from the rim toward the drain outlet, whereby overflow water discharged by a cooking vessel will drain from the plate through the outlet thereof and further provided with openings arranged in such radial relation to each other to register with the spaces between the radial flanges of a standard gas burner.

4. A safety plate for gas burners consisting of a plate formed with an upstanding annular flow limiting rim and a depending tubular drain outlet located centrally of the rim, said depending outlet being adapted to fit into the central opening of a gas burner the plate being formed with openings located between the rim and the drain outlet and the marginal edges of said openings being formed with upstanding flanges.

5. A safety plate for gas burners consisting of a plate having an annular upstanding flow limiting rim and a drain outlet, the surface of the plate being inclined from the rim toward the outlet, the plate being formed with radial openings spaced circumferentially from each other and the marginal edges of the openings being formed with upstanding flanges of less height than the rim whereby heated air may flow through the radial openings and discharge outwardly of a pot supported on the upstanding flanges or Water overflowing from such pot may drain between the flanges into the outlet.

6. A safety cover top for gas stoves consisting of aplate adapted to cover the top of a gas stove having'a plurality of gas burners in approximately the same horizontal plane, the plate being formed with safety portions for each gas burner, eachsafety portion having an upstanding flow limiting rim within which a cooking vessel may be placed, the surface of each safety portion within said rim being inclined for drainl age, each safety portion being formed with a depending outlet to discharge overflow water away from the jet openings of the gas burner,
