to circiiilate throughout the room. Children.

or others, who may be near by, may become asphyxiated before they are aware ofthe danger.

It is one of the objects of this invention to obviate this hazard, and to provide. a

burner protector which will permit the burn-.

er to function in its normal manner, and which will at the same time render it impossible for the flame to be accidentally extinguished.

It isa further object of this invention to provide a burner protector which permits suiiicient air to circulate between the top of the burner and the protector to allow the flame to burn properly.

It is a further object of this invention to provide a burner protector which is simple in construction, inexpensive to manufacture, and well adapted for the purpose described.

With the above and other objects in View, the invention consists of the improved burn.- er protector and all its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing, in which the same reference characters designate the same parts in all of the views:

Fig. 1 is a top View of the protector in I attachment with a burner, part of the burner beingbroken away;

Fig. 2 is a sectional view taken, on line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1;

Fig. 4: is a fragmentary view of the burner and protector showing an end view of one of the burner wings; and

Fig. 5 is a sectional view through one of the wings of the burner showing a modified form of protector in attachment therewith.

Referring to the drawing, the numeral 8 designates a burner of a standard type which is formed with a central body portion 9 having an opening 10 therein, and having a plurality of wings 11 extending radially outwardly. The top of the burner has aplurallty of perforations 12 for the discharge ofthegas. i i Q The improved protector 13 comprises a sheet of metal of the same shape as the top of the burner, having downwardly bent edges 14 which overlap the. edges of the burner. The central portion of the protector has an opening 15 to correspond with the opening'lO in the burner. The edges of the opening 15 are also downwardly flanged.

as at 16. The opening 15 in is somewhat smaller than the the burner to provide a space enter.

All of the downwardly flanged edge portions are corrugated as at 18. These corrugat'ions permit air to enterunderneath the protector, and also permit an outlet for the flames from the burner. The edge corrugations extend slightly over the top of the b11II1Gl,'S0 that the protector will reston the corrugations and will not. fit tightly on the top of the burner, but will leave a small space 19 as shown in Fig. 8.

the 1 protector opening 10 in 17 for air to .The upper surface of the protector is,

formed with radially extending corrugations 20 which extend from theopening 15 to the outer edges. These corrugations are above the perforations 12 of the burner and allow a supply of air to enter from the center opening 15. 8

In the. the edge corrugations 18 extend considerably further over the edges, and the protector is supported by these corrugations and held in a raised position. The top of the protector is formed with an inverted cupshaped portion 21 which leaves a large space 22 between the top of the burner and the protector. By having this large space, it

is unnecessary to have the corrugations 20 used in the principal form.

It is to be understood that the particular shape of the protector may be varied to fit burners of difl'erent types and shapes, the main features of the invention residing in the provision of a protector which will properly cover the burner and still allow ample air to enter to permit the burner to function properly.

To use the device, it is placed on the burner as indicated, and the gas is turned on. The latter will emanate from the sides modified form Shawn in Fig. 5,

through side corrugations, and may be ignited with the cover in place. The flames will rise from all of the edges of the protector and will be divided up and spread out so as to render it very eflicient for cooking. The flames will of course be burning underneath the protector also, so that if a liquid boils over it will not reach these inner flames and hence cannot extinguish the burner.

Furthermore, if a food such as a cereal boils over, the protector will prevent clogging of the burner perforations.

From the foregoing description it may be seen that the improved burner protector is very simple in construction and is well adapted for the purpose described.

W hat I claim is:

1. The combination with a burner having fuel outlet perforations therein of a protector therefor comprising a sheet of material covering said perforations so as to protect flames issuing therefrom being extinguished by overflowing material and having portions spaced from said perforations, and having downwardly flanged corrugated edges overlapping the edges of the burner, providing spaces through which air may enter to the spaces above the fuel perforations to maintain the burner in ignited condition.

2. The combination with a burner having fuel outlet perforations therein of a protector therefor comprising a sheet of material covering said perforations so as to pro-,

tect flames issuing therefrom from being extinguished by overflowing material and having portions spaced from said perforations, and having downwardly flanged vertically corrugated edges overlapping the edges of the burner, providing spaces through which air may enter to the spaces above the fuel perforations to maintain the burner in ignited condition.

3. The combination with a star-shaped burner having fuel outlet perforations therein of a protector therefor comprising a starshaped sheet of material covering said top and having portions spaced therefrom.

a. The combination with a burner having fuel outlet perforations therein of a protector therefor comprising a sheet of material of substantially the same shape as the top of the burner covering said top so as to protect flames issuing therefrom from being extinguished by overflowing material and having portions spaced from said top, and having downwardly flanged corrugated edges overlapping the edges of the burner, providing spaces through which air may enter to the spaces above the burner top to maintain the burner in ignited condition.

5. The combination with a burner having fuel outlet perforations therein and having a central opening, of a. protector therefor comprising a sheet of material of substantially the same shape as the top of the burner, and having a central opening of smaller diameter than the central opening of the burner, said sheet of material covering the top of the burner so as to protect flames issuing therefrom from being extinguished by overflowing material and having portions spaced from said top and having downwardly flanged corru gated edge portions overlapping the edges of the burner provid-' ing spaces through which air may enter to the spaces above the burner to maintain the burner in ignited condition.

6. A burner protector comprising a sheet of material of substantially the same shape as a burner adapted to completely cover the burner to protect flames issuing therefrom from being extinguished by overflowing material, and having downwardly flangech corrugated edge portions and upwardlyraised top portions to permit air to enter between the top of the burner and the protector to maintain the burner in ignited condition.

In testimony whereof I aiiix my signature.
