ELEcTnIoHEATINo ATTACHMENT FOR cansunn'rons.

Application filed March 13, 1920. Serial No. 365,410.

To all whom. it may concern:

Be it known thatwe, JOHN E. GODMAN and JOSEPH M. GARE, citizens of the United States, and residents of Lafayette, county of Tippecanoe, and State of Indiana, have invented a'certain newand useful Electric Heating "Attachin'ent .for Carburetors; and

we do hereby declare that the following is a full, clear and exact description thereof, reference being had to the accompanying drawings, inwhich like numerals refer to like partsf The chief ob'ect of this invention is to provide the car uretor or the intake manifold of an internal combustion engine with an improved heating element for assisting the,- evaporationfo'f' the hydrocarbon fuel atomized and carb'urized by the usual carburetor. v

The mainfeature of the invention consists in oonstructin the improved heating element of suitable materials and operating the same from the battery of the motor vehic-leor the Iikef,of which the engine is a part.

Another feature of the invention consists in positioning the electrical heating means adjacent the walls of the fuel intake passageway such that the efficiency of the fuel suppl is not impaired.

A fiirther feature of the invention is that the heating means may be supplied to the carburetor flange and inserted therein after recessi the same.

The ull nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Fig. 1 is an elevation view of the invention showing the same applied to an internal combustion engine. Fig. 2 is an enlarged plan view of the heating element with a portion broken away to show other parts in detail. Fig. 3 is a central sectional view taken on line 33 of Fig. 2.

In Fig. 1 there is shown an internal coinbustion engine provided with the usual exhaust manifoldll, intake manifold 12, and carburetor 13. The invention in this figure is shown positioned between the ends of the intakemanifold and the carburetor and secured thereto by suitable means, such as the bolts 14 and the like.

The improved heating element comprises a body portion 15, substantially elliptical in form. Said body portion near the extremities of the major axis is provided'with a' plurality of openings 1,6 adapted'to receive the bolts 14 for securing said heating element to the carburetor or the intake manifold, or both as desired. The body portion 15 is provided with a central circular opening 17 exter din tlierethrough. Communicating with sai circularopening and concentric therewith is an annularsemi-circular groove 18. Positioned'within said grooveisa semiannular shield 19 which serves to direct'the heat centrally and away from-the-body portion 15, as well as electrically insulate the individual coils 20 of the substantially annular, helical, electric heat" coil 21: The heating coil 21is 'ovid with terminal posts 22, said posts lieing suitably insulated from each otherand the body portion 15 by means of the insulating plate 23 'and'insulating bushings 24, substantially as shown. Suitable nuts 25 secure the circuitwires to the heating element. r F

The electrical circuit is herein shown comprising the usual storage 'battery 26, a switch 27, suitably positioned on the cowl, or dash, the ammeter 28, and the ground connection 29. Insulated wires connect the battery, switch, ammeter and heating element in series, as shown, and said heating element will be energized when the switch 27 is operated to close the circuit through the battery.

As shown clearly in Fig. 2, the carburized mixture will pass u wardly through the exposed portions of the annular, helical heating coil and be heated to further vaporize the hydrocarbon fuel. In Fig. 1 the-heating element is shown positioned between the adjacent receiving end of the intake manifold and the discharging end of the carburetor. Said heating element, however, may be positioned in the flanges of either the intake manifold or the discharge portion of the carburetor. The heating element also may be positioned upon the intake manifold and upon the discharge portion of the carburetor such thatthe heating coils 21 will be in contact with either of said parts, as desired, instead of in direct contact with the carburized mixture. 'When not in direct contact with the carburized mixture, it will, of course, be understood that suitable electrical insulating material must be interposed between the metallic intake or carburetor and thehea.ting,. x )i ls.- The. preferred, most. ecuopening thereth rough for the passa e of fuel no "cal ind easily mountedi'operuting posi-gi to he engine, an annular electri'czil heating tion is that shown in Fig. 1, wherein the ciement surrounding snicl central openin" heating coils 21 are directly exposed to the and secured to the inner wall thereof, sai sfiiisuigfcarbfirize'd-'inixture'nndthe hizting -element beinginrrunged to= extend-fepartially 40 element is interposed between theadjacent into said opening and leave a central free k end of the intake manifold and the discln i'gpassage thciethrongh.
