LIQUID-HYDROCARBON GENERATOR.

Application filed July 5, 1913.

T0 all whom t muy concern:

Be it known that 1, SIMEON l?. Pinnen, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful improvements in Liquid-Hydrocarbon Generators, of which the following is a specification.

My invention relates to improvements in generators for generating gas from heavy hydro-carbon liquids, kerosene, its object being particularly to provide a construction in which heavy hydro-carbon liquid, such as kerosene, are generated with the same effectiveness as the lighter liquids, such as gasolene, are generated in the ordinary constructions.

ln carrying out my invention l employ, as shown, a double generator, heated in operation bv a sub-flame, the hydro-carbon liquid being vaporized before passing into the generators. I also preferably employ means for pulverizing the contained hard carbon to fine particles to prevent blocking of the passages, together' with other coperating features for bringing about the complete generating of the gas and maintaining a constant flame of maximum etliciency.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

ln the accompanying drawings forming part of this specification, Figure 1 is a side elevation of a street lamp, broken away, and fitted with my invention; Fig. 2 is a vertical section of my improved generator; Fig. 3 is a top view of the same; Fig. 4 is a section on line mof Fig. 2; Fig. 5 is a section on line y-g/ of Fig. 2; Fig. 6 is a section on line e-e of Fig. 2; Fig. 7 is a detail of the end of the valve needle; and Fig. S is a sectional view through the needle valve orifice plug.

Referring to the drawings, A. represents the generator casing of a burner embodying my features of invention. rThe Generator is formedwith a central mixing tube 2. i A plug 3 is inset in the bottom of the tube 2 and is formed with a jet orifice 4, a needle valve 5 having screw threaded support in the bottom of the burner to extend into said oriiice, as shown in Fig. 2.

ylhe mixing tube is open at its lower end to the outer air, and is connected with a source of fuel supply through the medium Specification of Letters Patent.

of the following parts: 7 represents an inlet tube for the hydro-carbon, a vaporizing chamber 8 being shown supported upon the rllhe chamber 8 is filled with movable parts 9, as shot, for the purpose hereinafter more particularly pointed out. The chamber 8 at its upper end 10 is adapted to be detachably connected with the inlet port 11 of the generator chamber 12, said chamber extending around a portion of the mixing tube 2. rEhe generating cham ber 12 is connected by a downwardly and laterally extending conduit 13 with a second generating chamber 14 extending around the lower end of the mixing tube, the lower generating chamber 14 at its lower side being connected by a conduit 15 with the jet orifice 4. The

chambers

12 and 14 constitute spaced generators extending around the central mixing tube 2. The

generators

12 and 14, as shown, are preferably iilled with movable parts, as the shot 16. lThe casing A is shown constructed with an open top tube 17 extending upwardly outside of the mixing tube 2, a plurality of sub-llame openings 18 being formed through the wall or casing between the upper end of the mixing tube and the outer' upwardly projecting tube 17. The mixing tube 2 is formed with an upwardly extending portion 19.

1n carrying out my invention lf provide a gallery 20 fitted, as shown, over the outer tube 17, the gallery having a downwardly concaved top and being formed in said top with a central opening 21 of less diameter than the mixing tube, z'. e. the tube 2 and its extension 19. A suitable mantle 22 may be l'itted over the gallery, as shown, any well known form of support, as the support 23, being employed. The support 23 includes a screening 29 standing above the gallery and supporting a central plate 30 standing above the opening 21. v

ln the drawings, I show my generator arranged in connection with an ordinary street lamp, the generator being supported from the supply pipe 24 leading downwardly from the supply chamber 25 arranged within the framework of the lamp 26. The lamp 26 may be of any well known construction.

My invention is designed particularly for eliciently utilizing hydro-carbon liquids as kerosene in sub-flame generators, thus saving the heavier expense of using lighter hydrocarbons as gasolene.

1n use, the burner,l including the gener ator chambers 12iand 14, areiir'st -thoroughly heated as by a torch. While thus heated communication withv the source 01":

uelsupplyl is established, as by means of fthe hand valve 27. The hydro-carbon liquids pass fromV the inletpipe into the vapor- Y izer Sjwherein itf is vaporized, the vapor .passing therefrom into the upper generating cl1amber12. Y As shown in Fig.A 2, the outlet opening for the `vaporizer stands in the v upperg'endthereof, allowing the heavy impurities in .the oil to settle. The fuel is,

partly gasiied in the upperi generatingY 'Y lchamber `12 and passesfthrough the Qconduit "to thelower generating chamber 1 4, whereinV the gasification is completed.

` From the-lower chamber 14 the gas passes through the conduit 15' and oriice 4 to the mixing. tube 2. Y In Vthe mixing tube the gas is mixed with .the air which is drawn in through'the side openings 28 inthe lower u end of the mixing tube, the mixed air and 'gas passing Athrough the upper end of the mixingtube against the top of the gallery and through the central opening inthe gal-V v3.0 downwardly between the top of the mix- Y ing tube and the outer tube 17 passing 18 toform the sub-flames.

through the sub-flame 'openings 18, being ignited asthey passthrough the openings As indicated in Fig. 2, the sub-'llames strike against the top of the lower generatingchamber 14 and are dellected back against the upper generating chamber 12, ,thus thoroughly heating Vboth generatingfchambers Vto bringabout the doubley generation necessary in carrying'out my invention. doublegenerator with the inclosedV top gallery and the upwardly extending mixing tube the sub-'flame is producedV at a point particularly close to the needleA without igniting the gas entering the mixing tube fromV the needle orifice. The lower generator` chamber, as illustrated in Fig, 2, contitutes a partition between the sub-flame and needle orifice. A w f The sub-flame, inaddition to heating the double generator, heatsl the vaporizing chamber 8V and kthe contained balls 9 as well as the Aballs within the generating chamber. The balls9 and the balls 16 within the generating4 chambers are kept in aV state of agitation by the boiling Vof the .hydro-carbon and generating of the gas, pulverizing anyl hard carbon preventing blocking of the passages.

A portion of the" By the combination of the utilized forthose purposes. I secure by the features of construction shown a generator in which heavy and relatively cheap hydrocarbon liquids, as kerosene, may be as elliciently used as the higher priced lighter carbon liquids as gasolene.

`and mixing tube, a generator chamber surrounding tlie lower end of the gallery, a connected generator chamber surrounding the lower end of the mixing tube below said orifices whereby to deflect the sub-flame from saidorices upwardly against the op posed generator chamber, said lower generator connecting with a main jet orifice opening into the lower end of said mixing tube.

2; A burner of the class described comprising a central mixing tube, a gallery surrounding the upper end of said mixing tube and having an opening registering with the open top of said tube, the wall connecting the lower end of said gallery and mixing tube being formed with downwardly directed sub-flame orifices, a generator chamber surrounding the lower end of said gallery, a connected generator chamber surrounding said mixing tube below said subflame orilices whereby the sub-fiames will strike against the lower generator and be deflected against the upper generator, the lower end of said mixing tube having lateral openings to the outer air and said lower generator being connected with a main jet oriiice alining with the bottom of said mixing tube below said lateral openings.

3. A burner of the class described comprising a central mixing tube, a gallery surrounding the upper portion of said mixing tube and spaced therefrom, said burner being formed with downwardly directed subflame orices intermediate of the gallery and mixing tube, a generator chamber surrounding the lower end of the gallery, and an outwardly directed portion surrounding the lower end of the mixing tube below said orifices whereby to deiect the sub-flame from said orilices upwardly against the opposedy generator chamber, said generator chamber connecting with a main jet orifice openinginto thellower end of said mixing tube. y
