There are provided is designed. at diametrically opposite points on said burner 95 With the foregoing and other objects in view a pair of upstanding pins or lugs 13, which are which will appear as the description proceeds, the adapted to cooperate with a pair of recesses 14 invention consists in certain novel and improved provided in the under side of the stem 11 for features of construction, arrangement and comsecurely holding the attachment in place on the bination of parts hereinafter more fully deburner. The attachment may be made of any 100 scribed, illustrated in the accompanying drawsuitable material, such as iron or the like, which ing and particularly pointed out in the appended material is adapted to retain the heat for a conclaims, it being understood that various changes siderable period of time after the supply of gas in the form, size, shape and minor details of the has been shut off.

As shown more accompanying drawing a preferred embodiment clearly in Figure 3 of the drawing, the project- 1 ing portions 15 of the hood are also curved as shown at 16, so that the meeting edges of the outer and inner curved surfaces of the hood portion 12 will come to a distinct point to form a sharp edge as shown at 15 in Figure 3, whereby the dropping of liquid onto said outer curved surface of the hood 12 will result in said liquid dropping off said hood at the edges 15, which will be beyond the escape-orifices.

By reason of the curved inner surface 16 of the hood, the possibility of liquid traveling along said surface and down the stem 11 will be practically avoided. By reason of the above construction it will be apparent that should any liquid be spilled onto the hood 12, the same will roll off the side portions thereof without coming into contact with the escape-orifices to cause the extinguishing of the flame issuing therefrom.

A further feature of this construction is that it will not be possible for a gust of wind or the like to cause the extinguishing of the flame. The reason for this is if this gust of wind should strike the burner on one side thereof, it will be noted that it will only be possible to extinguish the flame issuing from the orifices disposed on the side from which the wind is coming, and it will not reach those orifices disposed on theinside of the burner, or on the outside of the remote side of the burner. For that reason there will always be a sufllcient number of orifices still left burning so as to prevent the extinguishing of the entire flame issuing from the burner.

It will thus be noted that I have provided a simple and inexpensive device, which may be readily disposed in place on a gas burner, and when so disposed it will not only prevent the extinguishing of the flame by reason of any spilled liquid onto the burner, or by any gusts of wind directed against the burnenbut will also act as a heat retainer for a considerable period of time after the shutting ad of the gas supply.

It is believed that my invention, its mode of construction and assembly, and many of its advantages should be readily understood from the foregoing without further description, and it will be manifest that while a preferred embodiment of the invention has been shown and described, for illustrative purposes, the structural details are, nevertheless, capable of wide variation within the purview of my invention as defined in the appended claims.

What I claim and desire to secure by Letters Patent of the United States is:

l. A gas burner having in combination a supply tube, and an annular gas receiving chamber, said chamber being formed within a ring, the upper portion of which is contracted and is provided with inner and outer concentric lines of orifices arranged just below the uppermost edge of said ring, and an attachment disposed on the upper edge of said ring being of substantially T-shaped cross section, the stem portion of said attachment resting on the upper edge of said ring and the hood portion of said attachment projecting over both of said inner and outer lines of orifices, the projecting sides of said hood portion terminating in sharp edges.

2. A gas burner having in combination a supply tube and an annular gas receiving chamber, said chamber being formed within a ring, which ring is provided at its upper portion with inner and outer lines of escape orifices arranged just below the uppermost edge of said ring, and a member of substantially T-shaped cross section disposed on said upper edge of said ring, means for detachably securing said member in place on said ring, the upper portion of said member having side edges thereof projecting over the said lines of orifices, the underside of said projecting portions being curved.
