CARBURETER.

SPECIFICATION forming part of Letters Patent No. 622,489, dated April 4, 1.899. Application filed J'uly 19, 1897. Serial No. 645,132. (No model.)l

To all whom t may concern/.-

Be it known that I, Lnonmns L. KELLY, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Oarbureting Apparatus, of which the following is a specification.

My invention relates to an apparatus for the manufacture of illuminatinggas from volatile oils, and is especially adapted to carbureters which employ numerous pipes connected together in series, which contain the oil and through which the air or lgas to be carbureted is also passed to commingle with the oil.

My invention consists in a certain novel construction and arrangement of tubes and intermediate chambers in connection with a superposed oil and gas holder, in certain novel means for supplying` oil to the said pipes and for delivering therefrom gas to the said reservoir, in certain novel means for commingling more thoroughly the oil and gas in the pipe con necting said intermediate chambers, and in a certain novel construction, combination, and arrangement of parts connected with the air-pipe of the carbureter for regulating the supply of air ,'thereto in proportion to the amount of gas generated and the number of burners to be supplied, the combination and.,

arrangements of parts being si1nple,`inexpen sive, and effective for the purpose stated.

In the accompanying drawings, which will illustrate my invention, Figure 1 is an elevation of my improved apparatus with a part of the casing of the carbureter broken away to more clearly show the construction thereof; Fig. 2, an enlarged detail, partly in section, of the air-regulator; Fig. 3, an enlarged section lof the air-regulating valve; Fig.4,an enlarged section detail of the air retarding and distributing air-pipe section; Fig. 5, aplan View of the air-distributing disk; Fig. 6, a plan view of the air-retarding disk of the said airpipe section, and Fig. 7 a transverse section of the cap and base of two radiator-chambers connected together.

The apparatus consists, essentially, in an air-reservoir 1, an air-pump 2, and a carbureter 3, suitably connected together by pipesections, the entire apparatus being adapted to be secured to any suitable base or iioor and easily coupled together or taken apart for repairs or for removalfrom one place to another.

The air-pump 2 is preferably and in the construction shown driven by a hot-air or gas engine 4, having a base 5 and a waterjacket 6, the air-pumps being connected by a pipe 7 to the air-reservoir 1 and the waterjacket 6 being connected by pipes 9 and 10, leading, respectively, to the lower and upper end of the water-jacket 6 and to a water-box 11, which latter is connected by a pipe '12, leading to the foot, and bya pipe 13, leading to the upper part of the outer jacket or cylinder of the carburetor. The carbureter is thus kept supplied withl a continuously-circulating body of water heated to a suitable degree by the gas or hot-air engine without additional expense or by a lamp 11a, placed below the water-box.

The carbureter-cylinder 3 contains a 'snitable number of sections 14a 14h le?, coupled together in series, each section being connected by a separate pipe 15a 151 15C with a pipe-section 8b, which leads 4from the air-reservoir, the said pipes 15 15b 15c being pro vided with stop-cocks 15e 15f 15g, respectively, to control the admission of air to the several radiator-sections.

The supply-pipe 15C connects directly with the base of the section 14C in this instance, and the pipe 15b connects with the cap of the said section 14, the air being thus delivered above the pipes of the section 14 in this instance, and the.pipe 15a connects with the cap of the said section 14", the air being thus delivered above the pipes of the section 14:1 and distributed more equally to the lower end of the pipes of the said section than would be the caseV were the air-pipe connection made directly to the base of said section. The sections let ltb 14C each consist of base-castings 14d, caps 14e, and tubes laf, connected together by screwthreads,the cap of each chamber being connected to the base of the adjacent chamber by an opening lag of suitable size. Theuppermost section 14 has a central pipe 1-7, which passes up through the bot` tom .of an oil-supply tank and gas-reservoir 18, connected at its upper end by a flange 1Sa with the underside of the cover of the carbureter. One or more small apertures 17 a in said pipe allow the oil to pass from the rcs- ICO of the pipe 17 opens freely to the space above the oil in the reservoir 18, and a gas-supply pipe 19 leads from the said reservoir to the burners. The pipe 17 prevents the air from acting upon the entire body of oil, thus preserving the quality of the oil until it enters the carbureter proper. The tubes 14f of the sections are each fitted at their lower ends with a retarding and distributing air-pipe section 20, which consists of a short metal tube having an exterior thread 20a, adapted to iit a corresponding inner th readof the said tubes'lif and provided with a retarding-disk 20h, provided with severalholes through which the air under pressure can pass, but in limited quantities, and is thereby retarded and admitted to an intermediate chamber 2Oc of the pipe-section 20, vthe upper end of said section and chamber being provided with an air-distributing disk 20d, having numerous small holes 20e therein through which the air must pass before it can reach the oil within the tubes laf, the disks 20b and 20d being preferably connected by a central stem 20f,

as shown in detail in Figs. 4, 5, and 6. The

` air under pressure is first retarded by the disk 2Ob and then iilling the intermediate chamber 2OC is caused to enter equally over the entire area of .the disk 20d and pass up through the oil within the tubes 141 to commingle completely and thoroughly therewith, the double perforated disks serving to check and prevent the air from puffing up into the tubes laf in jets which would leak up the sides of the tube and follow along the same to the gas-holder without sufficiently commingling with the oil to be properly carbureted.v 1

A check-valve 21 in the pipe 7, leading to the air-reservoir, prevents the air from passing back to the air-pump from the carbureter, and a similar check-valve 22 at the discharge end of the pipe 8a prevents the gas from flowing back to the air-reservoir after it has been ca rbureted. A stop-valve 8d in said pipe also serves to completely cut oit or regulate the discharge of air from the reservoir tothe carbureter, and an oscillatory regulator-valve 23 in the air-pipe 8n is cont-rolled in a novel vmanner by aV valve-regulating device, which will quickly shutoff the air under pressure from the reservoir to the carbureter Whenever the gas-holder within the same is properly charged and the lights are supplied therefrom at the proper andv predetermined pressure. This adjustment is effected with great accuracyv and with quick responsive action to the variability of pressure within the gas-holder by means of my improved valve-regulatin g mechanism, which consists in a cup 24, secured by a pipe-joint 24JL to the air-supply pipe 8, to the rim-flange of which is secured a exible diaphragm 24h by means of a ring 24, screwed or riveted thereto, the air passing through the joint 24Ca and pressing beneath the extended arca of the diaphragm. A rolling plate 25, se-

ervoir 18 down to the sections. The upper end I cured adjustably to a sleeve 26 by means of a stem 27 and nut 28, rests upon the top surface of the diaphragm 24", and a lever 29, pivotally supported at 30 upon a bracket 3l, secured to the pipe 8, is connected at its short arm with the crank-arm 28'L1 'of the air-regulating valve 23, a'weight 32, adjustably secured upon the longer arm of said lever, serving to nicely adjust the degree of opening of said valve and serving to quickly open and close the same with a very slight movement of the diaphragm and a corresponding slight variation of the pressure of air beneath the same. The jointed connection between the end of the lever 29 and crank-arm of the valve is sufficiently loose to allow the short arm of the lever to vibrate the crank with the greatest precision and rapidity to secure an accurate and sensitive responsive action of said airregulating valve at all times. The weight 32 may be adjusted to suit the quantity of air admitted, and thus adapt the carbureter to properly supply any required number of burners at any determined degree of pressure. The richness of thegas is regulated by opening any one of the cocks lf 15g, thus passing the air through any required number of sections. The temperature of the oil is raised to the degree best suited for completely decarbureting it by means of the water surrounding the sections, which is kept warm and in circulation within the carbureter-casing by means of pipes leading to the water-jacket around th'e hot-air or gas pump, which compress the air in the air-reservoir, thus providing in one apparatus easily set up or transported a complete gas-generating machine.

4The oil thus treated may be of the refuse or or When no engine is employed in connection with the apparatus, the water may be heated in any preferred manner, as by a burner or by any suitable heating device placed under a water-box connected to the Water-jacket of the carbureter. v

I claim as my invention and desire to secure by Letters Patent- 1. In a gas-machine, a carbureter comprising an oute`11 shell or casing, a series of oil circulating and commingling sections placed one above the other, each section consisting of numerous pipes secured at their ends to chambers, each chamber having an aperture communicating with the aperture of the adjacent chamber, the topl chamber of one of said sections being secured to the bottom chamber of the adjacent section in combination with a superposed oil and gas holder and a compressed-air reservoir connected with the bottom chamber of the pipe-sections of the said carbureter substantially as described.

2. A carbureter for gas-machines comprising a casing, a plurality of pipe-sections contained therein, connected one with the other in series, a superposed oil and gas holding reservoir, anda pipe secured to the bottom of said reservoir provided with perforations at its lower end to receive the oil and open at a retarding-disk provided with an opening or openings and located at the lower end thereof, a secondary distributing-disk provided with numerous openings therein at the upper end thereof, and a stem connecting` said disks, the latter being suitably placed to provide an intermediate air and oil commingling chamber, substantially as described.

In testimony that I claim the foregoing as -my invention I have signed my name in the presence of two subscribing witnesses.
