To all whom it may concave:

Be it known that l, itucti's'tuc M. SAN- BORN, a citizenof the United States, and resident of Stanford University, nty of Santa Clara, and State of GallLtoriua have invented certain new and useful lmpsovements in Oarbureters, oi which the following is a specification.

The invention relates to devices for vaporizing liquids and particularly to carburetors which are used in connection with internal. combustion engines for vaporizing hydrocarbons.

The object of the invention. is to provide a carbureter in Which the hydrocarbon is mechanically projected into the air current.

Another object of the invention is to provide a carbureter in which the hydrocarbon is projected in a circumferential into the air current. Another object of the invention vide a carburetei' in which the i to pro l oi the hydrocarbon is positive and vet es with the vide; a carburetor which is eiiicient in opera tion which eliminates the use of the needle value.

The invention possesses other tag e ous ieatiu'es, which, with the to go lg will be set forth at length in the following descriptionwhere I shall outline in full that form of the invention selected 1F illustration in the accompanying dra' which illustrates one form. of the curtail: i" of my invention partly in section.

The carburetor consists of cumin 2, preferably cylindrical in form, having; 2:1.81'7' tures 8 in the top and bottom Wells tner-eof to allow the passage of air thvethi'ough. These apertures are arrange teimedicte between the center and pe cry of the top and bottom Walls, thereby lining solid portions at the center. Secured the can ing, or formed integral therewith is the cap 4 provided with the customary vslve for regulating the How of the air theiethrough and with a flange 5 by means of which the carburetor is attached to the manifold oi' the engine.

Arranged within the casing 2 is a :tan 3 which is rotated by the 'air current passing therethrough, the speed of the tan being proportionate to the speed of the air current. T he fan is fixed on a shaft 1 which is pro vided on its lower end with an inverted cone shaped element 8. The upper end of the shaft 7 revolves in a hearing 9 centrally ranged in the top Wall of the casing and apex of the cone bears in the bearing 12 sic-- ranged in the boss 13 which is placed centrally in the bottom of the casing. The hydrocarbon supply pipe 14: connecting the earbureter with the float chamber 15 is secured in said boss and the bearing 12 is pro-- vided with apertures 16 to permit the hydrocarbon to pass therethrough. The float chamber is arranged so that the hydrocarbon stands up in thesupply pipe to such height that the lower end or apex portion of the cone is immersed in. the liquid.

The cone is preferably formed with con cave sides flaring outward at the lease, which for convenience Will hereinafter he termed a conczve cone. The sides of the coneshaped element are spaced apart slightly from the inner edges of the boss oruppers end of the supply pipe so that the hydrocarhon may pass itapward over the face (it t cone.

As the fan and consequently the cone is revolved by the current of air, the hydro carbon is forced along the face of the cone through the medium of capillary.attractiein and centrifugal force and is projected in a line circumferential spray into the air current where it readily becomes atomized. The base of the cone being a complete Cl?" cle, the hydrocarbon is projected from all parts thereof into the air current in the form of a sheet of line spray. As the position of the valve is varied to vary the speed and. power of the engine, the speed of the air current is varied and consequently the supply of hydrocarbon thereto is varied. The

hydrocarbon is therefore, positively fedinto the air current in a line circumferential spray which readily atomizes and the amount of hydrocarhou'projectcd into air current depends upon the speed oi?- the current.

I claim:

1. In a carburetor, a fan arranged the path of and adapted to he rotated by sir current and a conical shaped member partly immersed in hydrocarbon operatively connected to said fan and adapted proiect the hydrocarbon in a circumferential s way into the air current.

2. In a carburetor, a chamber provided With apertures for the passage of air there- [ill fill? through, fan arranged in said chamber in E the path of said air and adapted to be rotated thereby, an inverted cone connected to said fan, the apex portion of said cone being adapted to be immersed in the hydro:

carbon and the base of said cone lyingfor maintaining the hydrocarbon at a con sta-nt level in said pipe, an inverted concave tated by the air current, connected to said cone.

In testimony whereof, I have hereunto set my hand at Stanford University, Califi, this 4th day of May, 1912.
