THOMAb' W. PHILLIPS, JR, OF BUTLER, PENNSYLVANIA.

FUEL-BURNER.

SPECIFICATION forming part of Letters Patent No. 794,5e5, dated July 11, 1905.

Application filed April 14:. 1905. Serial No. 255,593.

To all whomit ntay concern.-

Be it known that I, THoMAs W. PHILLIPS, J r., a citizen of the United States of America, residing at Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Fuel- Burncrs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in fuel-burners; and the object of the present invention is to provide a burner by the aid of which the fuel may be economically used and to provide novel means for thoroughly mixing and commingling the fuel with air to increase the combustion.

The invention aims to provide means for artificially mixing air with a fuel, such as gas, and a novel form of burner is employed for ejecting the fuel into the mixing-chamber or air-tube at any desired angle to the axes or radii of the mixing-chamber or air-tube.

My invention aims to further provide a novel form of burner which will be inexpensive to manufacture, strong and durable, and highly efficient for the purpose for which it is used.

With the above and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts which will be hereinafter more fully described and then specifically pointed out in the claims, and, referring to the drawings ac-- companying this application, like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 isa side elevation of my improved fuel-burner. Fig. 2 isavertial sectional view of the same. Fig. 3 is a transverse sectional View taken on the line a w of Fig. 2. Fig. 4 is a fragmentary sectional view taken on the line 1/ y of Fig. 2, and Fig. 5 is an enlarged fragmentary sectional View of a portion of the burner.

To put my invention into practice, I construct the burner of a tubular body 1, preferably formed of one piece of metal by casting. The body 1 is provided longitudinally of its length with a central bore 2, serving functionally as an air-inlet to my improved fuel-burner. Formed in the body portion 1 and surrounding the bore 2 is an annular gascompartment 3, having an inlet 4:, said inlet being formed by providing the body 1 with a boss 5, having a screw -threaded aperture formed therein adapted to receive a suitable gas-supply pipe. (Not shown.) The body portion 1, diametrically opposite the gas-inlet l, is provided with a boss 6, havingascrewthreaded aperture 7 formed therein, in which a screw-threaded plug 8 is secured. The aperture 7 is provided, whereby the interior of the annular gas-compartment can be readily cleansed at any desired time. In forming the body 1 I provide the one end of the body with an annular beveled edge or face 9, the formation of said annular beveled edge providing a similar surface upon the interior of the annular gas-compartment 3 at one end thereof. The beveled edge or face 9 is provided with a plurality of circumferentially-arranged openings 10, the respective rows of openings 11 and 12 being staggeredly arranged. Each opening formed inthe beveled edge or face 9 is made tangential to, the axes or radii of the central bore 2, as illustrated in Fig. 3 of the drawings. In order that the direction of the openings 10 can be readily understood, I have illustrated in Figs. 4 and 5 of the drawings enlarged detail fragmentary sectional views of the beveled edge or surface 9. In connection with these figures it will be observed that the apertures are drilled upon a plane at right angles to the beveled edge or surface 9 and tangential to the axes or radii of the bore 2. The body 1, upon its end corresponding to the beveled edge or face 9, is provided with a peripheral enlargement 14, having threaded apertures 15 formed therein. Attached to the end of the body 1 is a threaded collar 16, said collar having a pierced flange 17, through which screw-bolts 18 pass and engage in the threaded apertures 15.

The reference-numeral 19 designates a cylindrical body, which serves functionally as a mixing chamber, and this body is screwthreaded upon its one end, as indicated at 20, whereby it can be secured in the collar 16, adjacent to the beveled edge or face 9 of the body 1.

When gas is admitted to the body 1 through the opening 4, the gas passes around the annular compartment 3, and when the pressure or intensity of the gas is suflicient it is ejected through the openings 10 of the body 1. The direction at which the openings are drilled causes the gas to be ejected in a spiral form, the gas adhering closely at first to the sides of the body or mixing-chamber 19, then gradually circulating toward the center of the mixing-chamber, where it encounters air entering the burner through the bore 2. A draft or suction is created by the passage of the gas into the mixing-chamber and air is drawn into the mixing-chamber rapidly, effecting a perfect mixing and commingling of the gas and air prior to its ignition, and consequently increasing the efficiency of the burner.

The particular feature to which I desire to call attention resides in the simplicity of the burner-body and the peculiar formation of the one end thereof, which assists materially in the mixing and commingling of the fuel and air admitted to the burner.

It is obvious that the fuel-burner is susceptible to various changes without departing from the general spirit and scope of the invention.

What I claim, and desireto secure. by Letters Patent, is'

1. A burner of the type described comprising a body having an annular gas-receiving compartment in its walls, with inclined faces at one end of said chamber, and having openings extending through said inclined faces and tangential to the axes or radii of the body, the said body having an annular port leading to the gas-receiving chamber, a collar secured to one end of the said body, and a mixingtube connected to said collar, substantially as described.

2. In a fuel-burner a hollow body having double walls forming a space between them constituting a gas-receiving chamber and an inlet-port to said gas receiving chamber, the inner wall of said body being at an obtuse angle at one end, and having openings extending therefrom tangential to the axes or radii of the body, acollar bolted onto the end of said body and a mixing-tube securing said collar, substantially as described.

In testimony whereof I afiix my signature in the presence of two witnesses.
