BURNER DEVICE Filed Sept. 15, 1950 ATTORNEY C. Hohensf g lg Patented Dot. 4, 1932 STAT BURNER nnvron.

. Application filed. September 15, 1930. ,Serial I- .e. ;E 2,113.

This invention relates to a burner, the general object of the invention being to provide a manifold with jets connected therewith and arranged at an angle so that the flames are projected against the walls of a fire box in which the device is placed.

Another object of the invention is to make each jet with converging air passages merging into the nozzle, with the gas nozzle arranged between the ends of the air passages and extending into the chamber formed by the converging passages so that the gas is thoroughly mixed with the air and the mixture escapes from the nozzle with great velocity.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of one of the jets.

Figure 2 is a sectional View through the jet.

Figure 3 is a plan view of the complete ,device.

Figure 4: is a section 011 line 4& of Figure 3.

In the drawing, the manifold is shown at A and the jets or burners at B. These jets extend upwardly and outwardly from the manifold, preferably at a 45 angle. The manifold is connected with the supply pipe 1 and its side portions are connected to the end 49 which is connected with the supply pipe by reducing elbows 2 so as to increase the gas pressure in the side and other end member of the manifold. The burners are connected with the Te 3 which form portions of the manifold, preferably by a nipple 4 which is threaded into the T and into a socket 5 formed in the gas nozzle 6. This nozzle is threaded into the bottom part of the body of the burner which is formed with the convergent wings 7 having the openings 8 at their lower ends and the gas nozzle 6 is located between the wings so that the openings 8 are arranged at opposite sides of the gas nozzle. The convergent wings form a chamher 9 and the upper end of the body forms an outlet nozzle 10 so that the air and gas mixed in the chamber 9 will pass from the nozzle. Due to the small bore of the nozzle 6, the gas enters the mixing chamber at a very high velocity, which creates a vacuum and thus the air is drawn through the openings 8 into the chamber 9, where it mixes with the gas. The atmospheric pressure, tending tov prevent the formation of a vacuum in the chamber 9, ins creases the velocity of the gas. The outlet end of the nozzle 10 is restricted, as shown at 11, and substantially semi-circular slots 12 are formed at opposite sides of the nozzle and provide inlets for air which aids the combustion. 70

The small size of the pipes used in the construction of the manifold permits the burner to be placed at the extreme bottom of the fire box, thereby increasing .the radiation surface area and the form of the manifold allows the burners B to be set at a angle, thereby spreading and bathing the fire by coming in contact with the fire box walls and covering more area than if the burners were set vertically. Due to the ar rangement of the double air ports, the proper area of the ports and the 45 angle of the ports with the gas nozzle at the center, the and air meet at a common center and form cross currents, thus making a highly combustible fuel, thereby increasing the temperature of the fire to a very high degree. By ging the semi-circular auxiliary air ports 12 close to the end of the burner nozzle, the as mixture passing the ports under pressure tenols to create a vacuum and draws in more air, thereby increasing the efficiency of the burner.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts,

let

provided that such changes fall within the scope of the appended claim.

What I claim is A burner of the class described comprising a hollow body formed with a vertical tubular portion and downwardly diverging tubular laterals with lower open ends, said body being further formed with an internally threaded center opening between the laterals in confronting relation to the'vertical tubular portion, and a nozzle adjustably engaged in the opening and having a contracted tip for extension into the body.

In testimony whereof I aflix my signature.

FREDERICK G. HOHENSTEIN.
