Specication of Letters Patent.

pplication led July 27, 1917. Serial No. 183,120.

To all whom itrmay concern:

.- Be itknown that I -others skilled in the art to which it apper- ,tains to make and to u'sejhe same, reference 4being had to the accompanying drawings, which illustrate the preferred rm of the invention, though it is to be understood that the invention is not limited to the, exact details of construction shown and de scribed, as it is obvious'that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:`

l,Figure 1 'is a longitudinal section taken `tlon' with-furnaces such as are employed for .vv- .-ft'he heattreatment or reduction of metals.

ltis a purpose to provide a low pressure air line which formsfa conduit opening at one end into the furnace interior, and to install in such conduitan atomizer in proximity to the conduit outlet. The atomizer will preferably be mounted on a standard which passes through and is rigidly secured to the wall of the conduit.

' Such standard contains a passage for hydrocarbon fuel,'wh1ch passage 1s 1n communication with a fuel discharge port in the atomizer. A supply line,` through which a fluid fuel is fed under pressure, is connected to the tubular atomizer standard outside the low pressure air supply conduit.

i Enteringl the low pressure air supply conduit in a different direction than the liquid fuel line, is another conduit for fluid that is under high pressure and is to be used for atomizing purposes. This high pressure line is connected to the atomizer, which has a blast port from which the high pressure Huid issues to disperse and atomize the liquid fuel. v The fuel s thus spra ed through the air in the low pressure air ine and with it is carried into the furnace in a proper combustible mixture. There is an arrangement of the fuel and discharge blast ports which results in an improved hydrocarbon spray, and a valve is employed that controls both ports, such valve being adapted to clear the fuel port of accidental obstructions.

Other novel features not specifically enumerated, but becoming manifest hereinafter, are, of course, to be regarded as coming within the scope of thepresent invention.

Referring now to the drawings, A represents in dot and dash lines a wall of any suitable furnace through an aperture in which projects the relatively large low pressure air line or conduit 1. Projecting Patented Feb.. 12, 191%.

interiorly and exteriorly through an apertured'boss 2 in the under side of the horizontal portion of conduit 1, is an atomizer standard 3. Said standard intermediate its length is provided with a iiange 4 adapted to rest on the upper surface of conduit boss 2 and its upper and lower portions are screw-threaded. A nut 5 is threaded onto the lowe'r portion of atomizer standard 3 to bear against the lower face of conduit boss 2, whereby said atomizer standard 3 is rigidly clamped to the wall of conduit 1. A pipe line 6 for oil or other hydrocarbon fue] is also threaded onto the lower end of atomizer standard 3' below nut 5.

Screwed or otherwise secured to the upper end of atomizer standard 3, is an atomizer generally indicated at 7 Said atomizer comprises a fuel receiving portion 8 and a portion 9 angularly disposed thereto and projecting rearwardly from the furnace, a

high pressure Huid line 10 being threaded into or otherwise connected to portion 9.

Atomizer portion 8 contains a pocket 11 y respectively. y The fuel discharge 'port inclines to one side as it progresses upwardly toward the mouth of blast port 14, whereby the liquid fuel, which is fed through port 12 under pressure, travels to a certaindegrec in opposition to the direction of the blast issuing from port 14. Such blast, which comes from high pressure line 10, will preferably be air, though it may be steam. Becauseof the predetermined opposition of the liquid fuel to the air blast,such fuel will be more harshly impinged against by the air blast and consequently dispersed into a finer and more greatly expanded spray. rl`hus the air which under low pressure travels through conduit l into the furnace interior, will be more perfectly impregnated with the hydrocarbon fuel, improving the combustion.

It is also to be noted that the upper horizontal part of atomizer portion 8 contains a Haring depression or passageway 15 which is directed toward the outlet of conduit 1 which enters furnace A. Such depression or passageway 15 is below. blast port 14, so that in instances where there is extremely high pressure in pipe 10, the blast which issuesI from port 14 will not choke off the su ply of oil through port 12.

ortion 9 of the atomizer is provided with an inclined face having the same angular disposition as that offfuel discharge port 12, which face forms a guideway 16 for a blade 17,'which constitutes a slide valve. Screws 18 are threaded into the portion 9 of the atomizer 7 and are spaced to be located on opposite sides of the slide valve 17. Such screws and the guideway 16 cooperate to definitely control the path of movement of slide valve 17 as lit is raised or lowered in response to an upward and downward movement of a valve stem. 19 to which siidevalve 17 is secured by countersunkrivets 20, or other I suitable means. Valve stem 19 passes through-an aperture in the thickened portion of the top wall of conduit l, its upper end being longitudinally slidable in a valve stern holder 21.

The bottom portion of valve stem holder 21 is provided with a plate-like formation 22 which is secured by tap bolts 23, or in any other suitable way, to the boss formed by the thickened portion of the upper wall of conduit 1, such plate-like formation closing conduit 1 where valve stem 19 passes through it.

yThe inclined substantially cylindrical portion of valve stem holder 21 is externally threaded to receive a valve-operating handwheel 24, the lower portion of which is formed to constitute a traveling nut thread-` ed onto the upper portion of'valve stem holder 21. Valve stem 19 is reduced in its upper portion and passes through top wall of handwheel 24. upon which rests a washer 25 that surrounds the reduced portion of valve stem 19 and is retained by a suitable pin 26 passing through the upper part of valve stem 19. U

When it is desired to carburet the air 1n low pressure air conduit 1, and supply' 1t as fuel to the furnace interior, handwheel` 24 is rotated to travel upwardly on the upper threaded portion of valve stem holderl 21. As it so travels, it raises valve stem 19,

Should the air blast from pipe 10 issuing 'i from port 14 be excessive, the liquid fuel n will not be prevented from issuing y and being atomized from port l2, but will pas through passageway 15. The; blast fofc may be regulated, however, by turning handwheel 24 to cause` valve stern 19 to lower slide vvalve 17 to partly close blast port 14,l and in this Way the mixture.' of air and atomized fuel can be regulated as desired.

Should foreign matter pass up through the liquid fuel line 6 and partially clog the fuel disclflargeA port 12, the slide valve 17, acting as a blade, may be further projected downwardly through the operation of handwheel 24 to pass through and clear port 12 of any obstruction. I

When it is desired to dispense with the use of the furnace, this. same operation will cause slide valve 17 to close both'the oilv discharge port 12 andthe air blast port 14.

Such excess of liquid fuel as may be out- 14. In this way, the oil is thinned out in .s

a non-resistive manner and-the air blast is ,applied to 1t. throughout its entire width resulting in vla further refinement of the mist-like dispersion of the fuel.

A low pressure air blast is supplied to' the conduit/f1 from any suitable source, as, 'i

for example. afan (not shown).
