GAS-GENERATOR.

Specification of Letters Patent. Patented'oct, 12, 192()f Application filed November 20, 1919. Serial No. 339,486.

i To all whom il?? may concern.'

The primary object of the invention is tol provide a simple, economical, accurately adjustable element, so arranged and constructed, as to prevent back pressure of the gas and to discharge an unbroken column of gas into the burner tube, whereby perfect combustion is maintained under varying low pressure conditions of the fuel gas.

The invention therefore embodies as its essential features a fluid supply nipple having an orificed tip provided withinternal conical walls, which converge toward the discharge orifice to form a choke bore. T he tip thus formed is equipped with a plug 1ncased therein having a conically beveled end corresponding in pitch to the conical bore of the tip, whereby the tapered surfaces of said tip and plug together form a parallel conically disposed smooth fluid discharge thereat leading to the orice, which throat isadjustable by a telescoping action wlthrelation to the tip and plug to contract and expand the throat in order to adjust the fuel supply.

The invention also contemplates the adjustment of the plug member or tip, whereby the conical throat is contracted or .expanded to vary the quantity of gas supplled to the burner under all conditions both as to volume and richness.

The invention also contemplates the embodiment of a simple and economical mixing chamber in connection with the burner tube together with means for varying the air inlet ports, whereby the supply of air to the burner is controlled and admitted uniformly about the solid column of gas which is vdischarged through the mixing chamber and.

into the burner tube.

WV ith the above and other objects 1n lview which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out'in the appended clalms.

, In the accompanying drawings has been i shown a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but

the right is hereby reserved to any changes, alterations or modifications to whichl re-v course may be had that come within the scope of the claims without departing from the spirit of the invention or sacrificing the efficiency of the same.

In the accompanying drawings: f Figure 1 is a bottom plane elevation with the furnace wall in cross'section, illustrating the entire mixing apparatus and' its relation to the furnace. Y Fig. 2 is a plan view of the burner, ignition plate and the mixing tube;

Fig. 3 is a longitudinal section of the apparatus,` with the operative elements in" elevation;

Fig. 4 isa longitudinal sectional view of` the mixing tube; and, 4. p. Y

Fig. 5 is a section on line 5 5 of Fig. 2.

Referring by characters to the drawings, 10 represents the pipe line leading from the reservoir 11 adapted for the storage of oil comprising the fuel utilized. This pipe 10 Y is connected by the elbow 12 to a similar pipe 13 having its threaded end lifscrewed into an opening formed in a sleeve 15 of semi-tubular construction. A pipe 16 leads from a tank 17 and is connected to the convoluted coil section 18 by a pipe section 19 and elbows 20.

' Pipes 10 and 19 carry globe valves 2O and 21, which are operable to regulate the feed of the oil and air respectively. A pipe 22 is connected to the pipe 23 of the coil section 18, which latter is positioned below the burner element to be later more fully described. v .v

A sleeve 1 5 is formed with an'interiorly disposed annular channel 24: and a centrally located tube 25 extends outwardly from the solid portion 26 of said sleeve to a point beyond the open end thereof.v The opposite end of sleeve 15 'is formed withy a restricted threaded `shank 27 on which is screwed a cap 28. As will bel readily seen, the annular channel 24 entirely surrounds the greater part of tuber andthe pipe 22 leading from the compressed air reservoir 17 opens into said channel 24.

The solid part of 26 of sleeve 15, is providedV with an Aopening 29 communicating with the hollow interior 'of tube 25 and the oil pipe 13 has its threaded end seated` into this opening 29, so that the fuel supply enters into the tube. j

The discharge end of tube 15 is formed with a Y concaved basin 30, the center of which basin merges into a central discharge orifice' 31 which forms a truncated valve seat 32 in the lwall 33. This wall 33 forms a chamber 34 within the hollow extension 35 of the said sleeve. Anipple36 is adjustably mounted upon the outer end of sleeve 15 and is formed with a restricted and out'- wardly projecting extension 37.V The outer vend of tube 15 extends into the extension 37 i of nipple 36 and the said nipple is connected tothe convoluted burner tube 38.

A needle stem 39 extends through Vopenings 40 and 41, in the cap 28 and shank 27 and into the hollow interior of the tube 25 of said sleeve 15.

The inner end of theneedle stem 39 carries a restricted shank portion 42 to which is secured the valve head 43 which "cooperates with the seat -32 in extension V34 of the sleeve. V'Ihe needle Vstem isthreaded at 44 at which point it engages an interior portion of the sleeveV 15. Likewise the outerv wardly andoutwardly with respect to said sleeve and tube 15, and to seat and unseat the valve Vhead 43 from seat 32. In this manner the flow of fuel oil passing through VtubeV 15 and into the extension through the restricted opening 33 is-regulated. f

The mixing of the air with Vthe fuel oil is eifected in the following manner:

' A hollow cylindrical casing member 47 is connected to the restricted portion 37 of nipple 36 and is formed with a closed outer end 48 which latter is formed with angularly disposed openings 49 and: a central opening. The restricted portion of nipple 36extends`through,the central opening of the casing member 47. j v

` The casing member 47, comprises the mixf ing chamber of the device and the relatively thin stream of fuel oil passes through the nipple 36 and'mixes with the heated air undercompression, just beyond the restricted portionV or extension 35 of the tube 25 and` for thoroughly breaking up the molecules j of air and fuel to provide a rich gaseous mixture, I pass the fuel vapors through a The air under compression is passedVV through the pipe coils v18 located directly under the burner 38 and .is consequently heated thereby, Vs'o that when it is delivered for? admixture with the fuel vapor its caloric intensity and value is greatly augmented and consequently the maximum degree of' commlngling of the air and gas molecules is effected.

An ignition plate 51 is connected to the casing member47 just below the burner 38 and justprior to igniting the gaseous mixture a quantity of gasolene' or free oil is placed upon the plate 51 and ignited, which action heats the air in coils 18.

For providing for an auxiliary air admission to the mixing chamber, 'I mount a mov able cap 52 ony one end of the casing memberl 47 and said ca 52 regulates the air openings 49.V Shou d -a greater supply of air be requiredl inthe mixing chamber, thisA cap 52 maybe adjusted to bring the openings 53 therein, in registration with the openings 49 ofsaid casing, to cut off the auxiliary" air supply, itwould only bevnecessary to adjust the cap 52 i to cover the casing openings 49.V f

y While in this speclcation the compressed air is employed it is understood'that if d`e` suitable gas may be' sired steam or other used. Y

Having' thus fully described my: invention, what I claim as new and desire to secure by Letters Patent is 1. A gas generator, comprising a-burner, a mixing chamber connected to said burner, a nipple adjustably mounted on said cham ber, a hot air supply pipe connected to said nipple, a gasolene or oil supply pipe formed interiorly of said gasolene pipe, a shaft extending long'itudinally within said gasolene pipe and having threaded engagement with I the rear portion of said gasolene and air pipe casing, a vtruncated conical valve head secured to said shaft for regulating the flow of gasolene or oil to the mixingv chamber, said nipple being adapted for'adjustment to regulate the hot air supplyl to the mixing chamber, an auxiliary yairsupply member mounted on said lmixing* chamber, a double truncated screen member disposed within said mixing chamber for breaking up the molecules ofV airv and gasolene introduced therein, and means whereby the air is heated prior to same entering the mixing chamber.

2. A gas generator comprising a burner, a mixing chamber connected to said burner, a nipple adjustably mounted on said chamber, a gasolene supply pipe, a hot air supply pipe connected to said nipple, a fuel supply pipe formed interiorly of said gasolcne supply pipe, a shaft extending longitudinally within said gasolene pipe and having threaded engagement with the rear portion of the said gasolene and air pipe casing, a truncated conical valve head secured to said shaft for regulating the flow of gasolene or oil to the mixing chamber, said nipple being adapted for adjustment to regulate the hot air supply to the mixing chamber, and an auxiliary air supply member mounted on said mixing chamber and means within the mixing chamber for breaking up the molecules of air and gasolene introduced therein, and means whereby the air is heated prior to its entrance to the mixin chamber.
