GAS BURNER Filed July 30, 1934 INVENTOR EM/L 01 501v ATTORNEY Patented June 2, 1936 UNITED STATES PATENT OFFIQE 1 Claim.

My invention relates to gas burners and more directly to the shape of the burner and the place and direction of some of its jet holes.

Burners used in the household gas stoves have flat or nearly flat tops with vertical jet holes so that the flame burns upward. The flat tops of the burner and the vertical jet openings insure no protection for the gas and flame and permit the easy entrance of liquids and semi-solid particles into the jet openings. Thusa strong gust of wind or an overflow of liquid or semi-solid material can easily extinguish the gas flame and cause asphyxiation.

An object of my invention is to construct a burner which will afford protection for some of its jet holes so that although the vertical upward jet hole flames are temporarily blown out or the holes stufied, key jet hole flames will remain lit and will in turn relight the flames extinguished.

A further object is to construct a burner with key jet hole flames some of which are always protected against a gust of wind irrespective of the direction from which the gust of wind comes.

Another object of. my invention is to construct in the usual manner of gas burner construction a simple inexpensive burner of a joined casting or of two castings joined together which will contain in itself and as part of the castings protected jet holes.

In order to accomplish these objects, I construct a burner with some openings protected by overhanging parts, the protected openings directed so that the flame from them intersects the projected direction of the openings of some of the unprotected holes.

Further and more specific objects, features and advantages will more clearly appear from the detailed description given below taken in connection with the accompanying sheet of drawings which form a part of this specification.

Figure 1 is a plan view of a star shaped burner with my invention incorporated; Fig. 2 is a section along the line 22 of Fig. 1. In the drawing I0 is a star shaped gas burner having the four hollow arms II at right angles to each other, a center portion I2, an inlet pipe [3 for supplying gas and the jet holes 14 through which the gas passes and where it is ignited. The jet holes are the customary small vertical openings for supplying small amounts of gas for the jet flames. These holes are spaced apart and in rows l5 of which there may be as many as desired along the top [6 of the arms.

In order to provide protected jet holes the end of each of the arms is provided with the upward extended part I! having the overhanging or forward bent part I 8 extending over the part [9 and protecting it from above. The part I9 is further sheltered by its curved extending sides 20. In

one part I9 is also protected against a gust of wind by its back part 2|. In the part l9 are the protected jet holes 22 which extend horizontally or slightly downward towards their exit so as to prevent the entrance of any liquid which may tend to extinguish the flame. The jet holes 22 in the part [9 are above the jet holes [4 and on a prolongation of the lines of jet holes I5, and there is at least one or more jet holes 22 at the end of each line [5. In this way the flames in the protected jet holes 22 are protected from being extinguished by liquids and wind and so remain continuously lit and because of their direction will relight the flames in the unguarded jet holes l4, and as the jet holes M are close together the heat of the flame in one of the holes I can relight the flame in the hole beside it.

The burner shown in the drawing is cast in an upper and a lower part and welded together, thus giving a strong burner with less possibility of leaks than if the burner had been constructed of separate parts and screwed together or in any other fashion. The simplicity of the castings of the burner with the protected parts as shown and described does not add materially to the difficulty of construction yet provides a sturdy burner with little possibility of leaks and with the desired protected jet holes.

While I have described my improvements in great detail and with respect to preferred forms thereof, I do not desire to be limited to such details and forms since many changes and modifications may be made and the invention embodied in widely different forms without departing from the spirit and scope thereof in its .broader aspects. forms and embodiments coming within the language or scope of the appended claim.

I claim:

A gas burner having intersecting hollow arms through which gas can pass, the upper surface of the arms being provided with openings through which the gas can escape, hollow end pieces of said arms extending above and toward the center of the burner, said end pieces having side extending projections one on each side of said end r Hence I desire to cover all modifications,
