Application filed December 10, 1926.

This invention relates to gasoline vaporizers.

Objects of this invention are to provide a device which may be attached between the carburetor and the intake niani old of a gasoline engine and which is actuated by the suction of the engine in. a manner to cause the thorough homogenizing ot the mixture, and the thorough atomization and breakingup of all particles oil the liquid which may pass to this portion of the systeul.

Further objects are to provide a rotary device which is enclosed in a small casing easily attached between the carburetor and the intake manifold, and so constructed that it will insure a perfect mixing); of the air and gas, and will also bring in and mix a small additional stream oi" air withthe miseturc so that a very perfect mixture results.

Fi'irther objects :H'OIO provide a device which is extremely simple and may be cheaply produced and readily applied, and which is so constructed. that it is 't ool-proot and does not require any attention whatsoever on the part of the operator.

Further objects are to provide a device which will trap a small amount of fuel when the engine is stopped, and which will litt this fuel up and mix it with the flowing: stream ot air orinixture passing to the engine and thus aid in the easy starting of the engine.

An embodiment ot the invention is shown in the accompanying drawings in which:

Figure l is a sectional view through the device showing a portion ot the carburetor and intake manifold such view correspond-- ing to a section on the line l-l of Figure 2:,

Figure 2 is LSGCtlOi'liil view on the line 2-E3 of Figure l;

Figure 3 is a rear view (it the apparatus showint it detached "ti-om the manifold and having a portion broken away for clearness of illustration.

Referring to the drawings, it will be seen that the outlet portion of the carburetor is indicated by the reference character 1 and. that the intake manifold is indi -ated by the reference character 2. The carburetor and nntniiold are provided with attaching flanges 8 and 4; between which the device is placed.

The device comprises a front casing 5 and intake i'i'un'iilold 2.

a rear casing (i which are provided with cylindrical recesses which together form a main recess of cylindrical contour reception of the rotary inelnber hereinafter described. 'llhese two sections oi. the easier; are boltei togetherby means oi? the lower bolt 7, and by means ot the attaching: bolts 8 which pass through the flanges 3 and 41 Furtl'ier it is to be noted that the casing (3 has a slightly larger internal aperture than the casing 5, and that the casing 5 is provided with a marginal flange 9 which tits within the uerture oi the casing; 6 and has a snug; lit therewith to make an air-tight and :tueltight joint. The casing 6 is provided with an elongated. boss 10 on its rear side provided with an aperture ll through which air may be drawn, such air dischargiiiig into the casing by means of a right angle aperture 12, as shown most clearly in Figure i It is to be noted from liiigure 1 that the casing 6 is provided with an entrance aperture 13 adjacent the upper portion of the nialn aperture and pretterably this entrance aperture tapei's, as indicated. liurther the casing 5 is provided with a short, projecting tubular portion l l whiclrlits within the The rotary nieinber conun'ises a hub per tion 15 provided with a plurality o't radially arranged slanting: vanes in. The outer ends of the vanes are jo red by a peripheral band 17 to secure strength of coiistriietion.

The rotary member is carried by the eularged central. portion of a pin as indicated at 18, such pin being provided with snnilier terminal portions 19 which fit within rorrespendingapertures formed in the main casmg.

The Illitlll casing can not become dis torted or bowed inwardly to interfere with the action of the rotary member, as the part-s are rigidly braced at their periphery, and are also braced at their central portions by means of the enlarged portion 18 of the central pin.

The rotary lTlQiHliCi' reely rotates upon the pin a sufiicient amount of lubricant beinn carried by the gasoline.

In the operation of the device, the ltlifk ture passes through the opening" 13 and through the tubular portion 14 into the intake inanifoht This causes very rapid rotor the that the fuel is thoroughly and completely vaporized, and that a substantially perfect mixture results.

It is to be noted that the rotary member is extremely light and travels at an enormous rate of speed with consequent thorough mixing of the parts of the flowing stream.

In addition to this, a small stream of fresh air is drawn through the openings 11 and 12 to an intermediate portion of the rotary member, and this air is thrown outwardly by the rotary member and thoroughly mixed with the flowing stream.

In actual tests conducted with this apparatus, it has been found that it may be interposed between the usual carburetor and the manifold, and that it will vastly increase the mileage per gallon of fuel.

Further, it is to be noted that the apparatus aids in the easy starting of the engine, as it will pocket any small amount of liquid fuel that may collect. Upon starting the engine the vanes churn up this fuel and mix it with the flowing stream of air or mixture, and thus insures a rich mixture passing to the engine.

It will be seen further that the device is very simple in construction and may be sold at a very small price. It is wholly foolproof and requires no thought on the part of the operator. &

Although the invention has been. described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim:

1. A gasoline vaporizer for use in connection with internal combustion engines, said vaporizer comprising a casing adapted for attachment between the carburetor and in take manifold of an engine and having a cylindrical internal cavity, a transverse pin carried by said casing centrally ol' the cavity, a rotor revolubly mounted upon said pin and having a plurality of radially slanting vanes, said casing having a pas sageway formed therctlnough and coustituting a continuation of the cavity through said carburetor and intake manifold said passageway being eccentric with reference to said cylindrical cavity, said vanes projecting part way across such aper ure.

2. A gasoline vaporizer for internal conn bustion engines comprising a casing having a vertical cylindrical cavity forn'icd therein and adapted to be clan'ipcd between the intake manifold of an internal combustion engine and the carburetor, said casing having an opening passing thercthrough and communicating with said cavity and connecting said intake manifold and said carburetor, a rotary member mounted within the vertical cavity of said casing and having a iiurality of radial angularly sct vanes, whereby the passage of the mixture through the aperture in the casing will rapidly rotate said rotary member and cause complete vaporization of the passing mixture. said cylindrical cavity being eccentric with reference to said opening and extending below said opening and stopping short of tho top of said opening.

In testimony that I claim the foregoing I have hereunto set my band at M ilwaukce, in the county of Milwaukee and State of \Visconsin.
