IMPROVEMENT'IN CARBURETERS.

Specification forming part of Letters Patent No. 177,210, dated May 9, 1876; application filed February 12, 1875.

To all whom it may concern Be it known that I, ISAAGIUOOK, of St. Louis, in the county of St. Louis, and State of Missouri, have invented a certain new and useful Improvement in Garbureters, of which the following is a specification:

The first part of my improvement consists in an improved form of supply apparatus or injector, to force atmospheric air, gas, or both,

into the carbureter.

The second part of my improvement consists in the construction of the operating mechanism of the injector-valve. In this the valve-stem has a radial arm, which is acted on by two spreading arms upon a head hav- -ing oscillatory movement upon the'valve stem or plug. This head has two flattened edges, upon which presses a spring to hold the head in position, whether the valve is closed or open, the sprin g also acting to carry the head around to such positions aiter it has been moved a certain distance 'by a lever connected with the rising and falling air-receiver, by whose descent the air, 8m, are forced through the carburetiug-chamber.

The third part of my improvement consists in the combination of an air-chamber or receiver, an arm projecting therefrom, a cocklever having a tilting-latch at its end, with a gasoline cook or valve. The tilting-latch allows the arm to pass down without operating the valve.

The fourth part of my invention consists in the combination of a cock-lever, tilting-latch,

slotted adjusting-plate, set-screw, and. arm,

with a gasoline-cock, for regulating the sup-- I tion of the machine. Fig. 2 is a side view of a part of the case, giving an end view of the injector by which the air is forced into the machine. Fig. 3 is a horizontal section at line X X, Fig. 2. Fig.4 is aperspective view of the gasoline supply-cock. Fig. 5 is an enlarged section of the injector at X- X, Fig. 3.

The case has a base, A, whose'interior constitutes the drip or waste chamber,A, for

the waste gasoline or surplus escaping from the carbureting-chamber. Around the top of the base is an annular water-trough, B, in which rests the lower edge of the maincase. The main or upper portion of the case has two concentric walls, 0 D, between which is an open-topped water-chamber, E, which receives the cylindrical part of the open-bottomed cover or receiver F, this arrangement forming a water-joint between the receiver and the rest of the -case, and allowing of the vertical movement of the receiver. G G are guides to the receiver, the said guides having bearing against the wall or shell 0. H is acord or chain attached to they top of the receiver and passing over pulleys I upon the frame J. At, the end of the cord H' is suspended a weight, K, which forms a partial counterbalance to the receiver, and by increasing or diminishing this weight the pressure on the current of gas within and issuing from the carbureter is regulated. L is the steam-pipe which conveys steam to the injector by which the air or gas, or both, are

forced into the machine. The injector has'a plug, M, tubular at the point, .and supplied with an adjustable screw-nozzle, N, and opposite to this nozzle is the mouth 0, of the receiving-pipe P. The axial steam-passage Q (in the plug M) communicates with the steam-pipe through a radial extension passing through the side of the plug and the case B. S is the orifice for the entrance of air, the

air passing into a cavity, T, around the 'noz-' zle N, which cavity is crossed by the steamjet by which the air is carried into the mouth O, and throught-he check-valve U, into the chamber V within the machine.- W is a pipe,

through which city-or other gas may be brought to mingle with the air in cavity T, and be carried with it into the machine.

The plug M has a passage, Y, forming communication between the pipe W 'and a pasv sage, Z, of the case, when the plug is in position to admit the steam, but said passage Y is closed simultaneously with the steam-pas of the head 0.

steam-cock, as the case 4 observed that while'the receiver is engaged movement the steam-cock is at rest, said cock is onlyturned as the receiver is ar- 'riving at 1ts extreme upper and lower positions. i i

sage through the cock. Upon the outer *side of the plug is an arm, a, by which it is turned, 1 throughthe medium of twoarms, b b, upon a collar or head turning freely on the plugshank, but held in either of the two' positions by a spring, (I, resting against flat edges 6 e plugshank. The head 0 is turned bythe following means: 9 is a leverfulcrumed on the 'plugshank, upon which (like the head 0) it turns freely. The outer end ot this lever'is connected by a rod, h, to the lifting-top 'or receiver F, so as""to "rise and fall with it, and as, it islnoved up and down, when near the extremes of oscillation, it comes in contact with the cross-pinsf, and turns the head 0 a distance suificie'ntto carry thevpoint e past the plane of the spring d, sothat thepressure of the spring will carryaround the hea'd c-the rest of thedistance'tofully close or open-the may be. It willbe in making the greater part of its (vertical) and" that The-mingled air and steam (eithenwith or "withou'tan admixturefof gas) enter the annular upper partlof the chamber V in a tangential direction, (so asto give a rotary movement to the contents of thechamhefl) and lpa ssupwardthroughthe annular, space between the wall D'and the Y wall 13 of the interiorcase, and so intothe'rcceiverF, which is raisedby the pressure, to make room forthe incoming gases," until, on the receiver arriving at its upper position, (as indicated in dotted lines in Fig. 1,) the stea'm-cockofthe injector 'is closed, and no more gases en ter the receiver until its contentshave passed through the carbureting cham ber and subsided to near its lowestposition,and the The receiver the receiver has injector-cock is again opened. on descending forces the air, &c., through the Thecarbureting-chamber q surrounds all the ducts" j and m. The sides t of the interior caseformtheouter sides of't'he carbureting chamber, and thetop r of the said case the top of said chamber. The central'part of the top 7* is formed of a removable cover,'r,fitting with an air-tight joint, to prevent the escape of carbureted gases removable cover is to allow access to the carbureting-chamber for the introduction or reinto the receiver. This At 'theends of1tbe 'ar'ms b b1 are cross-pins j, which :i mpinge against the. arm a when the head 0 is turned uponthe lever 2 upon the plate 4 moval of the fibrous or capillary'tmaterial placed in such chamber for saturation with gasoline. sis a pan to receive the gasoline flowing into it from the supply-pipe; and this 'pa'n'an'd the upper part of the carburetin g-chamber q in proximity to it I prefer to fill with cotton-waste, or some such substance which will readilypbecome saturated with the liquid, and convey it outward over the Whole upper part ofthe chamber, from whence it percolates through the sponge, sawdust, or'other suitableporous or fibrous substance with. which the carbureting-cha-mber q. is chiefly filled. The air on-gas(or the'mixture of the two,-as the case may he) passes up through the saturated material in chamber q and down through pipe t into the chamber u, from which 1 it (or they) passesout through theipipe o ito the gasburners.

The @gasoline orypetroleum entersthe machine throughapipe, to, leading fromi-a reservoir sufiiciently elevated to. givethetrequisite pressure to cause theflow ofgasoline into the machine against the in terior pressure therein. The flow of the gasoline.: is regulated by; a cock or valve, 3 opened,.each time the receiver rises, by a projecting arm, 3,.of the receiver coming in contact with the tilting finger or latch 1 at the'cndof the valve-lever 2. (The lever 2 is pivoted on the (plug-shank lot the cock y, and is secured to a plate, yhthatisattached rigidly tosaid,plug. ly is asct-screw, screwing intolthe lever 2and passinglthrough a slotyy, in the plate y.

. As the receiver descends the armf3 comes in contact with the top of th e outerg end of the tilting-finger 1, and, lifting up theh'eavierv inner end, passes, WlfllOLllij moving, the lever 2, and after the a passage 1 of the: arm 3 the finger 1 drops back into theposition shown in Figs. 1 and 4. The pipe to extends downward from the cock 2, then horizontally into the machine, and through the duct m, and its mouth to dis charges into the pans, where' thegasoline is absorbed by theporous waste) in the pan, and by such material :conducted outward to saturate the fibrous or porous material with wh ch-all of the cham ber q, beneath the level. ofthelpa-n, is filled. This latter material may consist of sponge,

sawdust, or any other materiaLcalculatedto upward vertically material (say cottonsustain the.hydrocarbom and to allowthe easy ascent of thera-irp'and to (give out the vaportothe air.

Any superabundance of gasoline drips through the bottom of the chamber q, and

passes through the pipe 4,.to the chamber u,

and down throughthevpipe 5 tothe trapti,

having holes 7 above the level of the lower end of the pipe 5, so asto shut off communication between the air in the waste-chamber A and the chamber V. The bottom of the chamber u, owing to the heat of the mingled steam and air entering the chamber V beneath it, is considerably heated and causes the evaporization of gasolinefalling or dripping upon it, and the said vapor will be carried outwith the carbureted air passing through the pipe (with the necessary steam) forced in by the injector, or with gas alone-in either casethe orifice through which the other fluid enters bein g closed-or both gas and air may be used.

.The pressure on the receiver may be regulated so as to force the gas through the burners at any desired pressure, and of this feature I propose to avail myself by using burners with an induction-opening for atmospheric air, which is drawn in by the current of gas passing through the burner, and mingles therewith so as to render the light more brilliant by the thorough mixing of the gas and air before ignition. To accomplish this to satisfaction, the pressure of the gas has to be up to a certain point. This application of the described burner would render it unnecessary that atmospheric air should be injected into the carbureter, as the city gas alone might be passed therethrough, and the air mingled at the burner, and there would be no explosive mixture in the machine. But, as with my carbureter there is no possibility of a burning substance being accidentally brought in communication with the interior, the described feature of absolute safety is not perhaps of much importance. The forcing of the air in by steam renders any form of mechanical blower unnecessary, but in addition to this negative advantage there is a great positive advantage in that the interior of the carbureter is heated, much increasing its efficiency, and rendering itoperative in cold situations in winter, where, without this provision, it could not work.

To heat the carbureter throughout, but

especially the carbureting-chamber q, I make the heated air to pass up all around the sidest' of the said chamber, and then downward through the ducts j, passing through the annular carbureting-chamber, and, after passing upward through the pipe I, downward through the pipe or duct m, extending through the center of the chamber. The carbureting-chamber q might be heated by allowing the heated air and steam to pass directly into it; but this would be objectionable, because the air should be freed from moisture before entering the carbureting-chamber,and this end is accomplished by causing the air to follow the devious course described and shown, in which it loses heat, and the moisture is condensed, the latent heat of the steam being given out to the air and surrounding metallic surfaces.

The condensed moisture in the annular chamber, between the wallsD and t, and that in the receiver F, except that running down the sides of the latter, finds its way into the trough B, forming the water-joint between the base Aand the upper part of the case, and the water escapes from the trough B through overflow-spout B.

The carbureted air is heated before leavingthe carbureter or machine by passingthrough the heated chamber u, this chamber being made hot by the heated air and steam in the chamber V beneath it.

I claim as my invention- 1. The supply apparatus or injector, consisting of the case B, provided with steam, air,

and gas supply orifices and passage T, and the plug M,-having passage Y, substantially as and for the purpose set forth.

2. The combination of the plug M, arm a, fork b b, spring at, lever g, rod h, and receiver! F, all operating substantially as set forth.

3. The combination of the receiver F, arm 3, cock-lever 2, having tilting-latch 1, with the gasoline-cock as and for the purpose set forth.

4. The combination of the cock-lever 2, tilting-latch 1, slotted adjusting-plate 1 screw 3 and arm 3, with the gasoline-cock y, as and for the purpose set forth.

5. The base, A having a closed top and water-joint, B, having an overflow-pipe, B, 'or its equivalent,in combination with the shell 0 of the upper or main part of the machine, forming an air-tight joint through which the water of condensation escapes, substantially as set forth. a
