Specification of Letters Patent.

Application filed November 16, 1918. Serial No. 262,889.

- To all whom it may concern:

Be it known that 1, WILLIAM P. BOYLE, a citizen of the United States of America, and resident of Chicopee, in the county of Hampden and State of Mass, have invented certain new and useful Improvements in Combination-Burners, of which the following is a full, clear, and exact description.

This invention relates to improvements in combination burners for use in burning oil or gas or both simultaneously, and one of the leading objects of the invention is the provision of a burner, wherein the gas nozzle can be detached from the air nozzle or adjusted thereon, so as to regulate the flow of gas.

Another object of the invention is the provision of a burner wherein the parts can be quickly separated.

With the above and other objects in view the invention relates to certain improvements, constructions, and combinations of pa its,

' clearly described in the following specification, and fully illustrated in the accompanying drawings, in .which: i

Figure 1 is a longitudinal sectional view of my improved burner.

Fig. 2 is a front elevation thereof. Referring to the accompanying drawings illustrating the practical embodiment of my invention 5 designates the body of the burner,

which is formed with the oil inlet 6, internally threaded to receive a feed tube or pipe,

and said body 5 is also formed with an air inlet 7, which is considerably larger in diameter than the oil inlet 6. The oil inlet 6 is separated from the air inlet 7 by means of a partition or wall 8-, which is formed with a small oil assage 9, closed by the end of the needle va ve 10. v

The needle valve 10 is threaded through a nut 12, which is threaded in the boss 13, formed on the body 5. A gland 14 is mounted on the stem of'the needle valve 10 to prevent leakage, and the outer end of thisv stem carries a suitable handle 15, whereby the valve may be suitably adjusted.

An oil pipe 11 is threaded in the division wall or partition 8, so that the bore of said oil pipe will be axially alined with the oil passage 9; A pipe or tube 16 is threaded in the opening 5' of the body 5 so as to provide a relatively large air passage 16 around the oil pipe 11. The forward end of the tube or pipe 16 is formed with a frusto-conical mouth 16". A burner tip 17 is threaded on the forward end of the oil pipe 11, and is .stream to the flame.

face of the tube 16, so as to maintain the needle passage 17 in true concentric relation to the bore of the tube 16. The mouth 16 of the tube 16 is concentrically spaced from the burner tip- 17 so as to provide an annular space 18 which surrounds the jet forming opening 17 I In order to render the burner useful for burning natural gas or any other gas, I mount a tube nozzle 19 on the tube or pipe 16, and this nozzle 19 is formed with an internal shoulder 19 which is threaded on the external threads 16 of the air tube l6, and provides a relatively large annular passage 20, formed in the air tube 16. The forward end of the nozzle 19 is formed frusto" conical and maybe moved upward or outward from the frusto-conical tip of the air tube, so as to var the gas stream flowing through the space tween the nozzle 19 and the air tube or pipe 16. Gas is admitted to the passage 20 by means of a gas inlet 21, which projects from one side of the body of the nozzle 19, and is shown tobeinternally threaded to receive a gas feed pipe.

When it is desired to clean the various parts all that is necessary is to unscrew the I nozzle 19, from thetube 16,.and then unscrew the tube 16from the body 5, thus clearing the burner tip 17, and permitting the removal of the burner tip.

Throughout the natural gas belt region the supply of gas is not suflicient in the winter to supply the needs of industrial establishments and households, and the law requires that the' supply be first provided to householders. This results in the industrial places substituting oil. These concerns naturally desire that oil be used with the same burners employed for using gas.

The great majority if not all concerns using oil burners desire at some time or other ized when converted into a gas burner or gas and oil burner and that the air supply be constant and automatically controlled by the flow of oil or gas and that the temperature of the furnace be not lowered by surplus air so as to require an excessive combustion of 011. v I

In the manufacture of combmed 011 and gas burners it is important that a minimum amount of metal be employed to limit the amount'of radiation of heat and to permit of the economical manufacture of the burners and their compact mounting.

Having described my invention I claim The combination with a burner body consisting of a casing provided with an oil inlet and an independent air inlet and a partition separating said inlets from each other and provided with an opening therein, means for closing said opening, an oil: pipe secured at one end to the partition to receive oil through the opening thereof, a burner tip on said -oil pipe, said casing being provided with a single outlet formed with internal screw threads, an air pipe threaded in said outlet and projecting from said casing and neeaeea' having a conically reduced outer end surrounding said burner tip, and a T-shaped cap having an internal shoulder threaded on said air p1pe and providing a concentric air space around said air pipe, said T having an gas supply, said T being detachable from said air pipe to permit the use of the elements remaining as a complete oil burner, and serving whenconnected to said air pipe as a means for providing a combined gas and oil burner or a as burner alone.
