BARNEY H. SPENGLER, OF LOS ANGELES, CALIFORNIA.

STEAM-INJECTOR OIL-BURNER.

Specification of Letters Patent.

Patented Mai'. 14, 1916.

Application filed June 18, 1914. Serial No. 845,916.

To all whom it may con cern Be it known that I, BARNEY H. SPENGLER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Steam- Injector Gil-Burners;y and I do hereby de- Clare 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, particularly to an oil burner in conjunction with a water leg and has for its object the provision of a novel oil burner in which means is provided whereby water is converted into steam by the burner, the steam being utilized for injection into the burner nozzle to produce a blast.

An important object is the provision of a burner of this character in which the blast runs parallel with the water leg, whereby the direct force of the blast will not be concentrated at too limited an area upon the water leg thereby increasing the length of life of the water leg.

Another important object is the provision of a burner of this character in which the head of the water vaporizer and the water leg are formed integral, thereby eliminating screw threaded connections or joints and providing a construction which will be subject to only the minimum of deterioration caused by expansion andcontraction.

An additional object is the provision of an oil burner of this character which will be simple, inexpensive in manufacture, efficient and durable in use and a general improvement of the art.

With these and other objects and advantages in view, the invention consists in the novel construction, arrangement and combination of parts as will be hereinafter more fully described and claimed, and illustrated in the accompanving drawing, in which,

Figure 1 is a side elevation of mv burner, Fig. 2 is a top plan view thereof, Fig. 3 is a vertical sectional view, and Fig. 4 is a cross sectional view.

Referring more particularly to the drawing the numeral 5 designates the side wall of the casing of my novel burner which is in the form of an annular shell closed at one end by a head 6 and closed at the other end by a head 7 having a water leg 8 formed integrally thereon. The heads 6 and 7 are securely clamped upon the shell 5 by longitudinally extending bolts 9 provided with nuts 10. The shell is adapted to contain water which should be preferably maintained at the level indicated at 11. 1n order that the height of the water may be kept constant, 1 provide a block 12 extending through the head 6 at its lower portion and provided with a valve seat 13 upon its outer end and also provided with three longitudinally extending openings 14 and 15, the openings 11 being disposed oppositely and on each side of the central opening 15.

pipe 16 is threaded upon the outer end of the block 12 and has its outer end closed by a cap 17. A water inlet pipe 18 communi- Cates with the pipe 16. A valve stem 19 extends through the opening 15 in the block 12 and has secured upon its outer end a valve 2O which is adapted to seat and unseat upon the valve seat 13. rFhe valve rod 19 extends into the shell 5 and is connected at its end to the short arm 21 of a bell crank lever 22 pivoted as at 23 upon a rigid bracket 24 and carrying upon its long arm 25 a hollow ball or float 26. Vhen the water within the casing falls below the level indicated at 11 the arm v21 will be moved toward the head 6 and the valve 20 will be unseatecl, thus allowing water to flow through the openings 14: in the block 12 and into the casing. TvVhen the water reaches the level 11 the upward movement of the fioat 26 and arm 25 will close the valve 2O and prevent the entrance of more water.

In order that the water may be heated. 1 provide blast burners indicated as a whole by the numeral 27 and comprising pipes 28 Communicating with the shell 5 at its top, extending longitudinally of the shell upon its exterior and terminating to the sides of and below the water leg 8. Oil feed pipes 29 extend from any Suitable fuel reservoir (not shown) and have their ends extending into the pipes 27 as shown at 30.

The operation of the device is as follows: Heat is first applied to the device by any desired means such as for instance a pan disposed below the device and containing a small amount of burning oil. or by means of a blow torch or the like. Oil vapor passing from the burner members 27 is lighted, whereupon the water contained within the shell 5 and water leg Z3 will be heated. After the water has been heating for some time, steam will be generated within the shell and will pass out under pressure through the pipes 28. As the steam under pressure passes out of the burner members Q7 with the oil vapor, a powerful and effective blast will be obtained, whereby the water within the shell will be rapidly heated' and will produce the proper degree of pressure for maintaining` the maximum eiiiciency of the burner. The water leg 8 extends directly into a furnace fire box as will he understood. It will beV noted that the water leg' 8 is adapted to extend directly into a furnace and that its diameter is such that a portion of the len' will be above the normal water level in the casing 5. Bv this construction it will be obvious that the water leg is substantially half filled with water and that the steam generated therein readily returns to the casing'.

It will be readily understood that I reserve the right to make various changes in the form. construction and arrangement of parts without departing from the spirit of the invention cr limiting the scope of the subjoined claim.

I-Iaving` claim:

In a steam generator, the combination of a casing having removable heads,l means, for feeding` water to said casing, a float operatthus described my invention, I

ed valve for controlling the ilow of water- In testimrny whereof I aliix my signatureg in the presence of two witnesses.
