ENGINE-FUEL varonrznn.

Application filed May 22, 1923. Serial No. emcee.

This invention relates to' internal combustion engines and has among its ob3ects to volatilize the fuel which condenses wh 1le passing from the Carburetor to the engine 111- take.

Further objects and advantages of the pres-- ent invention will be apparent from the "fol-.

lowing description, reference being had to the accompanying drawing whereln a pret I I 1n combination with a conduit through WhlCll ferred embodiment of the presentinvention is clearly shown. v The figure of the drawing is a sectional view showing a form of the presentmvention.

In the drawing, a carburetor 20 is connected by a pipe 21 and the neck 22 ofa va orizer 23 with the ,engineintake manifol 24.

Pipe 21 is, provided with holes 25 leading into the vaporizer 23.

A separate'heating chamber surroundlng the exterior of the vaporizer 23, which is provided with heat conducting fins 26, is provided by a jacket/27 having an intake 28 adapted to beconnected with the engine exhaustmanifold, and an outlet 29 for connection with a mufller. Jacket 27 is attached to vaporizer 23 by screws 30, and to pipe 21 by screws 31.

a The vaporizer provides a' relatively sharp annular portion or baflie 32 for diverting the condensed liquid fuel, which creeps upwardly along theinterior surface of. pipe 21 during the operation of the engine into the vaporizer 23. Here, the fuel will be vaporized due to heat transmitted by the fins 26 and walls of the vaporizer from the heating chamber 27. The vaporized fuel will enter the pipe 21 through the holes 25 due-to engine suction,

to the stream columniof fuel through the openings 25. i

lVhile the form of embodiment of the invention as described constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the.

scope of the claims which follow.

What I claim is as follows: 1. In a device of the-class described and a fuel mixture may flow to an internal combustion engine, a heatin chamber; a vaporizing chamber arrang betweensaid conduit and said heating chamber whereby the outer wall only of said chamber is heated, and the upper end of which vaporizing chamber is in permanently open communication with said conduit; and means'located adjacent the upper end of and extending into said vaporizing chamber for deflecting a portion thereof from the eriphery of the streamof fuel mixture flow ng along said conduit into said vaporizing chamber; said conduit 'having holes in its will whereby and through which the lower endof said vaporizing cham ber is laced in communication with the interior 0 said conduit. i v 1 2. In a device of the class described and in combination with a conduit through which a fuel mixture may flow to an internal combustion engine, a vaporizing chamber surrounding said conduit; and a heating chamher surrounding said vaporizing chamber;

said conduit having an opening adjacent and leading into the upper end of said vaporizing chamber, and another opening through which the lower end of said vaporizing chamber is placed in communication with the inte-' rior of said conduit; and a baflie plate ex-, tending into said conduit adjacent said first mentioned opening to thereby'defiect a part.

of the fuel mixture from the'periphery of the stream of fuel mixture flowing through said conduit into said va orizing chamber.

3. In a device of t e class described and in combination with a conduit through which a fuel mixture may flow to an internal combustion engine, a vaporizing chamber sur-.

roundin said conduit; a heating chamber said conduit into said vaporizing chamber; surrounding said vaporizin chamber; an anand a series of openings located adjacent the 10 nular passage adjacent an leading into the other end of said vaporizing chamber and end of saidvaponzing chamber the nearer the whereby-the interior thereof is laced in c'om- TS engine; an annular bafile plate arranged admunication with the interior 0 said conduit. 4 jacent said passage and extending into said In testimony whereofI hereto afli'x my sigconduit to thereby deflect fuel mixture from nature. 1 v
