Application filed September 19, 1916, Serial No. 120,997. Renewed August 10, 191?.

To all whom it may concern:

Be it known that I, GROVER 0. LONG, a citizen of the United States, residing at Lakeland, in the county of Polk, State of Florida,have invented certain new and use ful Improvements in Hydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

This invention relates to oil burners, and has particular reference to burners in which oil and steam are mixed to provide a burning fuel.

The object of the invention is to improve the construction of hydrocarbon or oil burners. In this connection,it is intended to so construct the burners that when they do require adjustment, the adjustments can be made by the simple operation of a single adjusting element. Furthermore, the device according to my construction is made entirely accessible for cleaning by the removal of a single head plate.

A further object of the invention is to construct a burner of this character in which the arrangement of parts insures a low oil consumption without waste from imperfect atomization. To this end, I have provided a burner in which the oil is vaporized, or brought to a state closely approximating vaporization, this vaporization being brought about by the use of the steam which eventually becomes mixed with the vaporized oil to form the fuel.

With the above objects in view and such other objects as may hereinafter appear, my invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a longitudinal section taken through the burner structure, certain pipe connections being shown in elevation,

Fig. 2 is a. section on line 22 of Fig. 1,

Fig. 3 is a section on line 3-3 of Fig. 1, and

Fig. 4 is a-longitudinal section of a modified form of the nozzle.

Referring more particularly to the drawings, 1 represents a cylindrical barrel which terminates at its front end in a conical head 2, and a tubular mouth piece 3. The rear end of the barrel 1 is closed by a head plate Specification of Letters Patent.

4:, which is secured to the barrel 1 preferably, by means of cap screws 5 which pass through a flange 6 formed on the rear end of the barrel. The central portion of the head plate 1 is formed into a boss 7 which is centrally apertured to receive a heating coil 8, the latter being surrounded where it passes through the boss 7 with a packing 9 held in place by a bushing 10. The stem 11 of the coil is threaded substantially throughout its length to receive the adjusting wheel. 12, the latter having an annular flange 13 upon its inner face which bears upon the face of the boss 7. Thus when it is necessary to clean the burner, removal of the face plate 4 gives complete access to the interior of the barrel 1, and when it becomes necessary to adjust the burner within the barrel, the coil can be readily positioned by means of the hand wheel 12. The coil 8 may be constructed with any suitable material such as brass or iron and is provided with a suitable number of coils, and terminates in the axially projected stem 14 which may ride longitudinally through the spider 15 secured between the walls of the barrel 1. The head or nozzle 16 which is mounted upon the forward end of the stem 14 is a frusto-conical shell having its rear face 17 centrally apertured and bossecl so as to be threaded upon the stem 14:, and having its forward end positioned so as to partially close the inner end of the tubular mouth 3 with its transverse web or face 18. The periphery of the nozzle 16, near the largest circumference thereof is provided with an annular series of openings 19 through which the oil or vaporized oil escapes at right angles to the direction of the stem 14. Thread ed into the tubular mouth 3 is the nozzle pipe 20 of the burner, which may be of any suitable length to meet the requirements of the particular furnace in which the burner is being used, but which is seldom less than twenty-four inches in length. The forward end of the nozzle pipe is fitted with a nozzle 21 of any required type.

' The pipe 22 is the oil supply pipe and is connected to the rear end of the stem 11 by means of a union 23, which is of such character as to permit the adjustment of the coil. A valve 2 1 controls the supply of oil to the coil 8. A. steam pipe 25 enters the barrel 1 through the wall of the latter near the rear end of the burner, and a bypass 26 from the pipe 25 to the oil pipe 22 provides for the removal of sediment from the coil 8 and the nozzle 16.

From the foregoing, it will be evident that I have constructed an extremely simple and practical burner which embodies the principles of vaporizing and atomizing fuel. The construction is such that a very high degree of temperature is attainable, and by reason of the preliminary vaporizing of the fuel, no'particles of oil emerge from the burner to incrust the boiler sheet or tubes and there is practically no soot or carbon.

In the form shown in Fig. 4, the coil is dispensed with, this form of burner be ing sometimes employed where superheated steam is accessible. Instead of the coil 8, a

continuous stem 8 is carried in the boss 7 and the spider l5, and the action of the super-heated steam upon the oil in the stem 8 vaporizes it almost completely before it passes out of the nozzle 16, and the action of the. steam on the remaining liquid causes its atomization before it reaches the nozzle 21.

What I claim as my invention is 1. A hydrocarbon burner, comprising in combination, a cylindrical barrel terminating in a conical head, an oil coil mounted in said barrel, a nozzle on the forward end of said coil, a nozzle on said barrel and a steam inlet for the barrel, said nozzle on the coil forming with said conical head a restricted passage, and having openings for ejecting vaporized oil against said conical head across the path of the steam passing to the nozzle of the barrel. 7

2. A hydrocarbon burner, comprising in combination, a cylindrical barrel terminating in a conical head, an oil coil mounted in said barrel, a nozzle on the forward end of said coil, said nozzle being positioned in fitted and slightly spaced relation within the conical barrel head, means for permitting ture, in the presence of two witnesses.
