BURNER OR PREHEATING TORCH.

Application filed October 19, 1921, Serial No. 508,799. Renewed October 11, 1924.

To all whom it may concern.

Be it known that I, lVALLIs Anxnn Mo- Cox, J12, a citizen of the United States, and a resident of McCoy, in the county of Atascosa and State of Texas, have invented certain new and useful Improvements in Burners or Preheating Torches, of which the following is a specification.

The present invention relates to an improvement in burners or preheating torches, and has for its object to provide a device of this character which efliciently generates its own fuel gas from kerosene or similar hydrocarbons; which provides for a complete and uniform mixture of the gas and air; which is readily controlled; and which is simple and durable in construction, reliable and eflective in operation and easy and inexpensive to manufacture.

Other objects and advantages of the invention reside in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which Figure 1 is a view in longitudinal section, illustrating the preferred embodiment of the invention; I

Figure 2 is a view in elevation with the jacket removed;

Figure 3 is a view in transverse section;

Figure 4 is a plan view;

Figure 5 is a detail view in longitudinal section'of the burner; and

-Figure 6 is a similar view in transverse section. 1

Referring to the drawings wherein for the'sake of illustration is shown the preferred embodiment of the, invention the numeral 10 designates generally a enerator or retort preferably constructe of a single piece of pipe and comprising a series of spaced, parallel and

coaxial convolutions

11, 12, 13, 14 and 15, and U-shaped connections 16, 17, 18 and 19. The connection 16 affords communication between the convolutions 11 and 12, the connection 17 between

convolutions

12 and 13, the connection 18 between

convolutions

13 and 14 and the connection 19 between

convolutions

14 and 15. The eonvolutions are not complete circles and the ga s thereof are alined and through these alin gaps the pipe which makes up ;the retort is extended to provide an outlet 20 from the generator. The connections 16 and 18 bear on one side of the outlet pipe 20 and the connections 17 and 19 bear on the opposite side thereof and are staggered with respect-to the connections 16 and 18, thereby strengthening and organizing the generator.

An inlet pipe 21 for the kerosene or other fuel is connected with the convolution 11 of the generator coil and is looped, as at 22, to provide a handle.

A jacket 23' is provided for the generator coil and is secured thereon by clamp bands 24 and bolts and nuts 25.

To the outlet pipe 20 of the generator coil, a burner pipe 26 is connected bya reducing coupling 27 The upper end of the burner pipe is provided with a goose-neck or return bend 28 to which the burner designated generally at 30 is connected. 7

The burner 30 comprises a body portion 31 having its upper end tapped, as at 32, whereby it may be threadedly connected with the goose-neck 28 and having the periphery of its upper end of polygonal form to facilitateturning. The threadedopening 32 communicates with a minute axial bore 33 which communicates with an axially extending cylindrical chamber 34 by means of a flaring conical passage 35. A circumferential series of radially extending air inlet openings 36 lead from the peri hery of the burner into the chamber 34. ring valve 37 is seated in an annular recess 38. which intersects the air inlet openings 36 and includes a plurality of imperforate segments 37 and a plurality of openings 37". The

segments 37 when alined with the openings,

36 cover and close the same and the openings 37 may be brought into full or partial registry with the air inlet openings whereby the inlet of air may be controlled and regulated. The ring valve 37 is split and the ends thereof are extended outwardly to form apertured cars 38 with which a stove bolt 39 or the like is associated so that the ring valve can be clamped in adjusted position.

In operation, the fuel, such as kerosene or other similar h drocarbon, is supplied under pressure to t e generating coil or retort through the inlet pipe 21. In the re-s:

tort the fuel is vaporized or gasified and in this state passes into the burner pipe 26 and goose-neck 28. As the fuel is supplied under pressure the gas thus generated issues in a jet from the minute axial bore or jet opening 33 into the chamber. Inv the 2a engaged by the U-shape chamber 34 it entrains the air and forms a burner from the generating coil, this being re'adily carried out by ad usting or varying the length of the goose-neck 28.

The burner 'can-be advantageously utilized for any purpose. where a large flame 1 is required such as preheating for welding purposes and for I claim: 1. In a burner, a generator constructed of a single piece of pipe and comprising pear burning for stock.
