CLARENCE ROBERTS, O'F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO ROBERTS & MANDER STOVE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORA- TION OF PENNSYLVANIA.

BURNER FOR- GAS STOVES AND RANGES.

Application filed September 28, 1928. Serial No. 665,361.

T 0 all whom it may concerm'.

Be it known that I, CLARENCE V. R03- ERTS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Burners for Gas Stoves and Ranges, of vwhichthe following is a specification.

My invention relates to certain improvements in burners for gas stoves and ranges.

The object of the invention is to construct the burner so that it can be located close to the edge of the stove, or range, and to provide a mixing chamber of such length that the air and gas will bemixed thoroughly before entering the burner.

In the accompanying drawings:

Fig. 1 is a plan view, partly in section, illustrating my improved gas burner;

ig. 2 is a longitudinal sectional view on tln line 22, Fig. 1;

Fig. 3 is a transverse sectional view on the line 33, Fig. 1; and

Fig. 4 is an inverted, sectional plan View of the burner.

vReferring to the drawings, 1 is the body of the burner, made in a single casting, having arms 2 radiating therefrom in the manner shown in Fig. 1. The body and arms of the burner are hollow, as shown. In the upper surface of the body and arms are a series of small perforations 3-for the escape of gas. At the center of the burner is an opening 4 for the passage of air to aid combustion. Depending from the two side arms are feet 5, in the present instance, which rest upon a suitable support and retain the burner in position.

6 designates a mixing chamber, extending from the center of the body 1 of the burner to a point beyond the front of the stove, or

range, as shown by a dotted line 7 in Fig. 0 The end of the mixing chamber is enlarged, as at 9. This enlarged portion, usulil ally, is located on the outside of the body of the stove, as shown. At the end of the chamber is a central opening 10 for agas pipe 8., which is shown by dotted lines. Around the opening are air inlet passages 11 that are closed by a valve 12, which can be turned to control the amount of air entering the mixing chamber.

Generally, the mixing chamber is connected to the front arm of the burner. When the burner is arranged close to the edge of a'stove, or range, the mixing chamber is short, consequently, the air and gas are not mixed thoroughly.

By my invention, however, the mixing chamber is extended under the burner, as shown in Fig. 4, and the inner end is bifurcated, as at 13, to pass on each side of the central opening 4. Short passages 14 form communication between 'the mixing chamber and the interior of the burner.

By this construction, the burner can be placed close to the edge of the stove, or range, yet the mixing chamber willbe of sulficient length to allow the air and gas to be mixed properly before entering the burner.

Furthermore, by separating the mixture and allowing it to enter the burner at two points, a better distribution of gas is attained.

I claim:

The combination in a gas burner, of a hollow integral casting forming a body portion having a central opening for air; perforated, hollow arms projecting radially from the body portion; a longitudinal mixing chamber extending under the burner and bifurcated at its inner end to pass on each side of the central air opening, the ends of the bifurcated portions .of the mixing chamber communicating with the hollow body .portion of the burner; and means for admitting gas and air to the mixing chamber.

CLARENCE v; ROBERTS.
