Application -fi1ed. July 5,

My invention consists in new and useful improvements in gas burners of the type adapted to be used in boilers, industrial furnaces and the like, and has for its object to provide a burner simple and durable in construction, easy to install, arid safe and venien-t to operate. v

Another object of my invention is to provide a burner economical in fuel consumption,

and one which, due to my particular arrangement, will not pulsate, blow out nor back tire.

A still further object of my invention is the quick and thorough mixing of air and gas at a point close to, but not in the burner.

\Vith the above and other objects in view which will appear as the description proceeds, my inventionv consists in the novel features herein set" forth, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

Referring to the drawings, in which numerals of like character designate similar parts throughout the several views,

Fig. 1 is a perspective view in side elevation, showing the assembled burner,

Fig. 2 is an end view vof the same,

Fig. 3 is atransverse section of the burner,

Fig. 4 is a detail sectional view showing the air control operating means, and

Fig. 5 is a sectional view taken vertically through the central portion of the burner.

In the drawings, 1 represents an air tube or cylinder, open at each end, and preferably composed of cast iron. VVithinthe tube 1, and near one end thereof, I provide a transversely extending yoke 2, supporting centrally thereof a cylindrical collar 3, .apertured to receive a set screw 4 for the urpo'se hereinafter set forth.

The collar 8 is apertured and threaded to receive an adj usting'and locking screw 9, which, for convenience, extends beyond the circum ference of said disk 7 and cylinder 1, being bent over to form a handleat its free end.

The use and operation of my improved gas burner are as follows;

Aren't 'oF 'IcE. i

Assuming that the parts of the burner are assembled and the device mounted in thewall of a furnace or the like, and the outer end of the pipe 5 connected to a source of gas supply, the disk 7 is adjusted on the pipe 5 to the desired position, to allow the proper volume of air to be sucked into the tube or cylinder 1 at the intake end, and the screw 9 isthen tightened to secure the disk 7 in place. It will thus be seen that as the gas is discharged from the aperturesin thegas distributor 6, it will be thoroughly mixed with the air sucked into the cylinder 1 through the space between said cylinder and the disk 7, and due to the angularly disposed apertures in saiddistributor 6, "said mixture will take place at a point close to, but not inthe cylinder 1,,whereby backfiring is prevented if the flame is turned low,

and the flame cannot be jerked out due to sudden changes in either draft or gas pres- 7 sure.

' From the foregoing, it is believed. that my invention may be clearly understood by those skilled in the art, without further description,

iirbeing borne in mind that numerous'change's may be made in the details of construction,

without departing from the spirit of the in vention as set forth in the following claims.

VVhatI claim and desire to secure .by Letters Patent iszj 1. a 1. A gas burner, comprising a cylindrical air tube, open at both ends, a gas supply pipe extending longitudinally through the center thereof, a gas distributor on one; end of said pipe,'and within said tube, having a plurality of converging jets, theother end of said pipe projecting outwardly beyond said tube, and a means 'slida-bleon said ipe' adjacent said tube,

for controllingthe in notion of air into the N tube.

21A 7 gas barrier as claimed in claim 1, wherein said gas distributor is provided with a plurality'of .gas apertures arranged in con- I centric circles and at an angle to the face of the distributor each of said apertures converging toward the adjacent aperture'in the same circle, whereby the streams of gas from the adjacent converging apertures, and the the streams of gas from the laterally adj acent air sucked through said tube between said apertures, and the air sucked through said apertures", impinge at a point exterior of said tube between said apertures, impinge at pre- 10 tube. a determined points exteriorof said tube.

5 3. A gas burner as claimed in claim 1, In testimony whereof I afiix my signature.

wherein said gas distributor is provided with g a plurality of gas apertures so arranged that JOHN 'S. ZINK.
