UNITED STATES ALIVIUS T. CAB/IVES, OF KANSAS CITY, IVIISSOURI.

FLUIID-FUEL BURNER.

Application filed December 8, 1923. Serial No. 679,415.

To all whom it may concern:

Be it known that I, ALMUs T. GARNES, a citizen of the United 3 States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Fluid-Fuel Burners; and I do hereby declare the fol lowing 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

This invention relates to fluid fuel burners, and has for its object to provide such an apparatus with means whereby the quantity of fuel supply may be regulated.

The features of my invention consist in the improvements in the jet mechanism of the burner apparatus, comprising openings in the tip of the jet which can be controlled by means of a thimble secured on said tip by means of screw threads so that by turning said thimble in one direction some of said openings will be opened, and in the reverse direction they will be closed.

These and other features of my invention will be hereinafter described and pointed out, and are illustrated in the following drawings in which:

Figure 1. is a side elevation of a fluid fuel burner provided with jet mechanism of my invention.

Figure 2, is a plan View of my improved jet mechanism removed from the burner apparatus on the line 22 in Fig. 1.

Figure 3, is an enlarged central section of the same on the line 3-3 in F in. 2.

Figure 4., is a fragmentary view of a portion of the apparatus.

In these drawings AA indicates a fluid fuel burner of usual and ordinary construction and operation, consisting of a hollow ring A, and a tray A in which the ring A is supported by a stem at, shown by broken lines, to the lower end of which the first supply pipe A is connected in the usual manner.

The ring A is provided with a threaded opening at its highest point above the inlet pipe A into which is screwed a jet tube B, which is provided with a conical tip B at its lower end. At the apex of this tip B is a small jet opening I), and through the inclined side of the tip B are placed a plu rality of small openings 6. Around the lower portion of this .jet tube B are screw threads B upon which is placed a thimble C, the internal opening in which is provided with threads which engage the threads B on the jet tube B. The chamber in this thimble is provided with a conical shaped wall which fits the conical tip B of the jet tube B, so that when the thimble C is screwed up to its limit the holes 6 in the tip B will be closed, as shown in Fig. 8. This thimble C is provided with a radial flange C having a series of holes therethrough adapted to receive the end D of a rod D, which extends to and is pivoted upon one arm of a bell crank lever, E, by means of which the flange C and thimble G can be rotated. The thimble C is provided with an opening 0 which registers with the opening 6, in the apex of the tip B, of the jet tube. Upon the upper end of the thimble C is secured a gland ring F by means of screw threads f in which is placed fire-proof packing 7, see Fig. 3, to prevent the leakage of oil. To yieldingly maintain the thimble 0 closed against the conical tip of the jet tube B, I provide a spring E so that when the chain E is released the spring E will operate to shut off the flow of fuel through the holes I) in the tip B of the jet tube B. The lever E and spring E are secured to the outside of the furnace (not shown) by means of a bracket E in which the burner is installed, the rod D and fuel supply pipe A passing through the walls of the furnace.

In operation, fuel is supplied to the ring A through the supply pipe A and flows outward through the hole 6 in the tip of the jet tube B where it is ignited. Should the fuel be liquid and therefore not ignite readily, it will be received in the tray A where it will ignite and in burning will heat the ring A and boil the liquid in the ring A and thereby generate gas in the upper part of the ring A, which will flow out of the jet tube, and ignite in the usual manner. In

case. more fuel is required the chain E is A sufiiciently heated to volatilize the liquid fluid in the ring.

Having thus fullv described 111 invention and the operation thereof so that others can utilize the same, What I desire to secure by LettersPatent is:

In a fluid fuel burner, a iet tube, a conical point on said tube having a jet opening in the apex of said point and a plurality oi jet openings in the conical surface thereofl an internally screw threaded thimble having a conically shaped shoulder therein coinciding with the conical point on said tube and adapted to control the jet openings in the conical surface of said tube. means to rotate said thimb'le, external threads on said thinnble, a gasket on said tube and seated on the upper end of said thimble and an internally threaded stufiing-box ring screwed on said thimble adapted to compress said gasket.

In testimony whereof l'afiix my signature.

ALMUS T. CARNES.
