vih/woo CARBURETEE.,

and l. do declare the 'following to be a iull,

clear, and exact description oi the invention, such as will enable others skilled in the art to which it appertains to maire and use the saine.

My invention relates to improvements in carbureters and more particularly to those which areintended for mixing steam. mixed. with air with the mixture oi fuel and air drawn from tbe device by the suction caused by the engine pistons. I am aware that numerous types of carbureters have heretofore been devised for carrying out this end, but the object. of the present invention is to provide a device of this class which may be constructed easily and inexpensively and the saine time result in an extremely eiiicient means for producing' the desired result.

lilith the foregoing general object in view,

the invention resides in the novel features of construction and unique combinations of.

parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying' drawings which iorni a part of this specification and in which:

Figure l is a vertical section ci the iinproved carburetei';

Fiets.4 2, 3 and l are horizontal sections on the planes of the lines 22, 8 3 and 4 4, respectively, of Figc. 1, looking in the directions indicated by the arrows;

Fig. 5 is a vertical transverse section on the plane indicated by the line 5-5 of Fig. l; and a y Fig. 6 is a detail longitudinal sectionl siini- 'lar to the upper portion of Fig. l, but illus trating a modified form of construction.

in the drawings above briefly described, the numerals i and l designate respectively a fuel reservoir and a Water reservoir, the

two lbeing preferably, though .not necessarily, cast integrally as shown clearly in Fig. l. The inlets of the reservoirsl and 1 are provided With any appropriate type of constant level device such as the floaty controlled valves 2 and 2', and in order that either gasolene or kerosene may be fed to the reservoir l, as occasion may demand, a pair of supply tubes 3 and arc provided,

either one of which may be placed in coin-- inunicatiou with the main inlet tube by means oi: a three-way valve 6. in inost in stances ,frasolene Will be used as `the fue? in starting, and until the engine has been heat ed to such a degree as to allow kerosene to be readily employed.` When this degree of heat is obtained, however, the valve 6 is Aoperated so` that kerosene, or any other rather heavy; oil, may be supplied to the chamber l.

Air passages .'Z and 7 lead vertically .through the tvvo reservoirs l and 1 respec tively, suitable nozzles 8 and -8 'being pon sitioned in said. passagesor supplying a spray of liquid thereto'as suction is created through said passages by the action oi: the engine, it being obvious that since said noz .zles communicate respectively with the reservoirs l and l', they will supply the passage 7 with fuel, whereas the passage will be furnished with a spray of Water. The upper ends of the passages 7 and 7 de liver into a pair oitubular perforated outlet members 9 and 9 which rest upon a horizontal plate 10 which is secured over and closes the upper ends of the reservoirs, the member 9 being1 preierably of less size than the member 9 since less Water than fuel is to be handled by the device. i peripheral wall iiieinber 1l rests on th plate 10 and is suitably secured thereto, said Wall ineinberhaving a transverse parti-tion l2 which divides the space circuniscribed by said ineinber, into a pair of heating cliain-.

pipe le extending` through both'chambers' 13 and 13 and having` means at its ends for connecting,l it to the usual or any pre erred type of exhaust manifold, so that the hot gases passing through said pipe will Aperforin the heating function effectively. Around the outlet members 9 and 9, the pipe lli is provided with anv annular series oit preferably tf-shaped lieatradiating' Webs l5 between which and other oblique Webs 15,", on the sides of the pipe 14, the fuel mixture and the mixture of water` vapor' and air must pass from said outlet members, before traveling to the upper ends of the chambers 13 and lffroin which the mixtures formed dell* .are Withdrawn. `The upper side of the flat pipe 14 will also in most cases 'be provided with heat radiating Webs 16 which are preferably arranged as depicted in Fig. 2, al-

though any other suitable disposition couldv well be utilized. A. top plate 17 closes the upper ends of the chambers 13 and 13 and is rigidly secured in place in any preferred manner, said plate ,having an outlet opening 18 leading from thechainber 13, and similar opening 18 which coinmunieatesyw'ith the `ehainloer 1. A suitable dome 19 rests on I and is secured to the plate 17, Said dome ex-- 'tendintr over both openings 18 und 18 ,andiV having a short vertical disehiu-ge pipe 20 which registere with the opening 18 as shown clearly in Fig. l, said pipe being adapted for tering the outlet pipe 20, is whirled arounf to insure thorough mixing thereof with the vvolatile mixture rising through said pipe from the chamber 13.

A highspeed air inlet 23 is provided iu the dome 19 for supplying an `auxiliary quantity of air to the passage Q0 when the engine runs faster than pre-determined speed.

allowed to mingle with the mixture in the,

rThe air from the inlet 23 may be dome ll), by the provision of a eonstruetion .stichs that illuutrated in Fig. (3. or a hori 'onta'l partition 24 may he provided in ,said dome, So that the mixture will be confined beneath thispartition, whereas the air conn ing into the intake will flow between t`h`e partition and the top et' the dome, and will enter thopipe 20 through perforations spaced above the perforatious 22 above de serileed. Either construction is highly eilieient and I merely illustrate both to dis- -lose the two ways of obtaining required result.

The improved efnfbureter is installed hy emmer-ting its outlet pipe 20 ""'th the iu lake i'nanit'old Q1, and eonneeti its euh pipe 'ifi with the exhaust manifold of the engine, as will beelear from Fig. l. Either A,grasolene or oil 'will now he supplied to the reservoir l through the tuhes 3, t and 5. and the valve 6, and the constant level dei vite will. cui; oil' A'the supply at .the valve 2, when it has risen to the required level in the nozzle` 8. Similarly, water is supplied to the reservoir l 'through the inlet pipe 5', and the autmnatie regulating' means oi the valve E2 culs oil the supplu when the water level has risen to the reiuaired extent. En starting Ithe i'notov;4v oler-ie will in most he tedv to the r: e5-voir to ineure easy a vipaaeae thehot pipe 14, so that this mixture is eonverted instantaneously into a mixture oli air and Steam, which passes into the deine lt* and then enters the pipe Q0 through the perfqrations 2:2 provided for this iurposi. Since the mixtures of air and i'uel and ail' and steam enter the pipe 20 at substantially; the saine point, an eii'eetive mixing takes place, particularly in View of the tangential arrangement of the perforation 2:1. and a highly volatilized mixture is thus insured which will operate the motor to irreal, ad. vantage.

Preferably used in connection with the features above described, is the usual ehehe valve 26 for the passage 7, and a siiwiia; valve 26 for the pasiage 7. lt may he necessary to use both of these ehoifes when starting, but in most cases it will only e necessarylto operate the valve 26', in order that Water .may not vhe drawn into the intake manifold and mixed with the gaeolene, since this would cause a low grade fuel he fore heating of 'the exhaust pipe.. Ar this heating takes place, however, the eh 26 may again he opened., together with tl 1 valve 26, if the latter has been eloeed, so that the fuel, Whether the latter he gasolene or oil, will be supplied with a quantity of steam and air mixture for producing the Well known results, :auch as increasing power of the motor and minimizing ear-hen deposits.

From the foregoing, taken in connection with the accompanying drawings, it will oo 'one hat although the improved earhu l'df) ,veter is of comparatively simple and inert-- pensive eonstruetiom it `will hief u cient and durable. Sinee probably results; are obtained :from the r talle shown and described, these 'features are Jy preference employed, but l wish it understood that Within the scope et 'the vention as elaimed,'numereus minor ehanges ,1
