To all whom t may concern.' i

Be it known that we, MANUEL R. RODRI- GUns and MARTIN J. SCHMITT, citizens of the United States of America, and residents of the borough of Brooklyn,` county of Kings, city and State of New York, `have invented a certain new and useful Can bureter; and we do hereby set forth such a full, clear, and exact description as will enable the invention to be fully understood by tho-se skilled in thepart.

This invention relates to `certain useful improvements in carbureters'to be used 1n connection with internal combustion engines in which volatile liquids, as for example, gasolene, kerosene, fuel oil or the heavier hydrocarbon oils, or other transient fluids may be volatilized or intermingled with air, so as to form a rich mixture, and preferably a rich explosive gaseous mixture, suitable for operating 'internal combustion engines.

The invention may also be utilized in order to serve as a. means for supplying air in a finely divided condition and intimately mixed with a volatile liquid, or with the vapor of a transient liquid so as to produce lelastic combustible fluid equable inquality, 'volatility and density and free from 1mpurities, suitable for use for illuminating, cooking or heating purposes if so desired.

According to our invention we employ certain means for distributing the hydrocarbon gas or other volatile fluid in .vsu'ch a manner that it will thoroughly mix with the air as it passes through a vessel from one end to the other, and more particularly to devices for mixing the air with the vapor by causing it to pass `across a charged fabric or other material or absorbent, porous or cellular structure. y

-ln its more detail nature the invention embodies certain novel features of construction, combination and arrangement of parts as herein set forth, and it has for its object the provision of an apparatus of the kind set forth forming in operation a simple `and eiiicient organization.

In order to enable the invention to be fully understood, we shall proceed to explain the saine by reference to the drawings, illustrative of embodiments of` our invention, which accompany and form a part of this specification, and in which `Figure l represents a longitudinal section of an apparatus constructed according vto our invention, Fig. la is a plan view of the same, Fig. 2 is a partial longitudinal section of another apparatus in which our invention is embodied, Fig. 2 is a transverse section of the same, Fig. 3 is a longitudinal section of another apparatus constructed according to our invention, Fig. 3a is a plan view, and F ig. 3" a transverse section of the same, Fig. 4 is a transverse section of another apparatus in which our invention is embodied, Fig. 4f* is a plan view of the same, Fig. is a longitudinal section of another apparatus constructed according to our invention, and Fig. 5 is a side elevation .and Fig. 5b an end elevation of the saine.

Like letters of reference indicate like parts in all the views.

`ln carrying out our invention in the spe- 'ciiic devices illustrated inV Fig. l, we e1nploy a preferably laterally disposed vessel preferably consisting of a casing made of any suitable material as for example, a casting made of iron or any other convenient metal or alloy, or of suitable sheet metal, which vessel `may be made integral, or preferably in sections of approximately equal size as illustrated at A, B, in Figs. l and 5, or the top portion of the vessel B may be formed so as to be detachable in order to serve as and to constitute a cover, as A, as shown in-Figs. 2, 3 and 4l, the said sections in either case being constructed and arranged to be rigidly held together in a gas tight relation.

rlhe vessel B is preferably constructed with a wall or partition E near the end thereof, whereby the vessel may be divided into two compartments or chambers C and D, although the chamber D may be located at a distance from the compartment C if so desired. y

The liquid fuel chamber D has, pref-erably, an opening 4t for the admission of the Vvolatile fluid, which chamber may be provided with means for regulating the introduction of the lliquid into the chamber 'C by any well known or suitable controlling apparatus such as is well known in the art, as for example, by the use ol a valve "7 controlled by a float 8 whereby `the carbureting fluid may be supplied to the mixing chamber 'C as fast as the consumption of the said liquid takes it out Iof the said receptacle. In Acase the liquid fuel chamber is located Vapart from `the vessel B, `the *fluid may be conveyed to the latter by means of a tube,

as 4a, extending from the vessel B, as illustrated in Fig. 5, or a pipe may be inserted in an opening formed in the casing of the mixing chamber as shown at 4b in Fig. 4.

The wall or partition E is preferably pro- .vided with means to afford communication between the chambers C and D which means may consist either of a longitudinal or horizontal slot 5 as illustrated in Figs. l, 2 and A 215er of a plurality of orifices 5a as shown in Figs. 3, 3a and 3b, which long slot 5 or orifices 5a preferably containing short wicks v5"-may be located at any convenient height l in the separating wall E.

The casing of the vessel A, B, may be of dual formation, as illustrated in Fig. l,

where the outer casing A, B, serves to prop vide a jacket for the vessel A, B, the intermediate space constituting a chamber F, through which hot gas or a hot liquid or other medium may be circulated.

The numeral 1 denotes a series of preferably solid depending baffle plates attached to the upper portion or cover A of the apparatus which ordinarily hang down to within a short distance yof the interior bottom of Athe vessel B. 2 designates a series of intermediate balile plates projecting upward from the said bottom of the vessel B which plates preferably reach nearly to the inte- .rior topA of the cover A. These plates are chamber C. The said baflie plates and ves- Vsel walls comprise a number of compartments comprising vertical portions and laterally disposed parts. The mixture contained within any one of the said compartments must pass through the fabric 3, supported by the plates l and 2, in order to reach the next forward compartment. The mixture is thus successively filtered, and, in-

. asmuch as'the fabric is not so moist at the far or exhaust end thereof as it is at the portion adjacent to the chamber D, the mixture becomes'drier as it approaches the outlet or exhaust Gr of the said chamber C.

The fabric 3, which may be made of cotl ton material or may consist of wicking or of any suitable absorbent porous or cellular structure, is preferably constructed and arranged so as to run in a sinuous manner between tlie baffle plates, which are ordinarily arranged so as to form a series of short lateral and relatively longer vertical passages of relatively large and small sectional areas,

the said fabric preferably being so held as j thevcompartment C. The wicks 5" are preferably employed in instances where slots 5 are used, in which cases it would not be practicable to extend the fabric 3 through the same. Such devices are ordinarily employed Y where the mass of carbureting liquid is supplied under considerable pressure and volume. In cases where liquid feed controlling means is employed in the chamber D, the orifices or slot in the wall E may be free so vas to give free access of the liquid to the fabric.

It will be noted that the vessel, baille kplates and porous material spaced therefrom are constructed and arranged to respectively form the alternate and inclined walls of a series of adjacent compartments each projecting beyond the median plane of the vessel.

The air to be carbureted enters the vessel through the opening Gr and flows through the vessel A. B. Owing to the relatively small channels or passages between the ends ofthe baiie plates and the casing the air current or jets become mixed with the vapor rising from the saturated fabric, and as the air, which is preferably forced through the vessel by means of a suitable fan blower, is thrown against successive layers of the charged absorbent material and the resisting baiiie plates, the circuitous passage of the air from the inlet pipe G to the outlet or service pipe G causes it to become thoroughly charged with the hydrocarbon vapor thereby forming a rich mixture suitable for illuminating, heating and power purposes.

It is noted that in our carbureter the liquid is not allowed to run along the entire bottom of the same without hindrance in the customary manner, as in suoli cases, where the entire apparatus is flooded, the absorbent material becomes thoroughly soaked and saturated equally well throughout its entire length, under which conditions it is impossible to prevent Small globules of the volatile hydrocarbon liquid from leaving the final or last carbureting chamber with the saturated vapor. In* order to prevent this,

the hydrocarbon liquid is fed solely into` or allowed to enter the first compartment of the carbureter alone. In the carbureter of this invention the absorbent material is only designed to be positively charged with the hydrocarbon liquid in the first chamber thereof. The air entering this compartment, and while under pressure, and taking the tcrtuous passage around and through the sinuous absorbent material located in the several compartments, will absorb enough of the hydrocarbon in the lirst chamber alone to become perfectly saturated. One of the main objects of this invention is to have the wicking or other absorbent material which is located in the last few chambers (and which is dryer than the forward part thereof) filter the charged air by absorbing such small globules of liquid as may be free or in suspension and which are ordinarily sprayed through a carbureter by the pressure of the air, so that there will be nothing left but a dry, highly inflammable mixture leaving the last compartment. To this end, as stated, the carbureting liquid is only allowed to enter one, i. e. the first, chamber,

where the absorbent material takes up enough hydrocarbon liquid by capillary attraction to meisten it, and the air passing through this moist wicking is carbureted, and after passing through successive dryer portions of the said absorbent material of the' respective compartments, leaves the carbureter in a dry state containing absolutely no globules of gasolene, benzin, or other liquid hydrocarbon. The said wicks, as 5b, are inserted in order to prevent the too free passage of the liquid through the inlet orifice, as 5, in cases where it is preferred to introduce the fluid by capillary action. This particular method is designed to be employed in cases where so rich a mixture is not desired, and also in connection with explosive engines where the cylinders are of small diameter. By the adoption of this invention, the passage of small globules of hydrocarbon liquids from the outlet of the carbureter into the explosion chamber of the engine is prevented, which dry vapor thereby produces an explosion that is practically an absolute combustion, causing practically no odor or smoke, as there is suificient oxygen present to completely oxidize all the carbon and hydrogen existing in combination in the hydrocarbon carbureting liquid, the resulting gases of combustion becoming practically odorless and smokeless, forming C()2 and H2O in vapor form which are both colorless and odorless. According to the ordinary methods usedl in mixing, or spraying the hydrocarbon and air into the explosion chamber, small globules of the liquid are carried by suspension into the said chamber, which causes a superabundance of hydrogen and carbon to; be present, and the oxidation of the carbon and hydrogen being incomplete, free carbon is liberated, and smoke and gases are emitted from the exhaust.

Copies of this patent may be obtained for It will be observed that the fabric is kept in a continuously charged condition, so that the area of the volatile liquid, is enlarged as much as possible before the air comes in contact with it although the woven material is not thoroughly saturated throughout its entire length, and by the peculiar construction and arrangement of the tortuous passages within the vessel the hydrocarbon vapor and air are kept in a state of contact and agitation by striking against the successive baille plates until the complete mixture of the two is effected.

The number of the baille plates may be proportioned to the quality of the oil or other volatile liquid employed.

The air may, if preferred, be drawn through the apparatus by suction, as, for example, in cases where the device is used in connection with an internal combustion engine.

Inasmuch as some portions or features of our invention may manifestly be used without all of the others, and as obvious modilications will occur to persons skilled in the art, and as our invention may be embodied in widely varying forms, we wish it to be understood that we do not desire to be limited to the exact details of construction shown and described.

What we claim as our invention is In a carbureter, the combination with a casing, of imperforate plates or partitions forming a tortuous passage for the air, said passage comprising a number of portions positioned at an angle tothe longitudinal axis of the casing and connecting longitudinally disposed parts, and a unitary porous material to pass successively through the various portions of the said passage, the said plates, casing and porous material being constructed and arranged to respectively form the walls of a series of adjacent communieating compartments, each projecting beyond the median plane of the casing, and means to charge the first chamber only with hydrocarbon fluid, said unitary porous material serving as the sole means of conducting the liquid from the first chamber to the others.

Tn testimony of the foregoing specification we do hereby sign the same in the borough of Brooklyn, city of New York, county of Kings, and State of New York, this 1st day of Dec., 1911.
