Uct. 15, 1929. E. KOSANEK ELECTRIC VAPORIZING ATTACHMENT Filed April 5, 1928 Enoeutoz [570/ fibsaimd Magnum Patented Oct. 15, 1929 UNITED STATES PATENT OFFICE ELECTRIC VAPORIZING ATTACHMENT Application filed April 5,

This invention relates to vaporizing devices and more particularly to electrical heating devices for vaporizing fuels for use in internal combustion engines.

As is well known, for eflicient operation of internal combustion engines, it is desirable that the fuel be completely vaporized before it enters the combustion chambers.

It is an object of this invention to provide an attachment which may be readily applied for use in connection with standard carburetors on internal combustion engines.

It is a further object of the invention to provide an electrical heating device for preheating and vaporizing the fuel before it enters the combustion chambers and which may be placed in operation from a remote point.

These and other objects are attained by the novel construction, combination and arrangement of parts, hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure, and in which Figure 1 is a side view of a carbureting de vice having my improvement applied thereto.

Figure 2 is a plan view showing one form of the electrical heating attachment.

Figure 3 is a side view of the device shown in Figure 2.

Figure 4 is a plan view of another form of the electrical heating attachment.

Figure 5 is a diagram showing the electrical connections employed.

Referring to the drawings, a carbureting device is shown at 7 and 8 provided with a crank 9 for controlling a butterfly valve of the usual type. The electrical heating attachment 10 made of suitable metal is positioned between flange 12 of the carbureting device and flange 11 of the intake pipe and, as shown in Figure 2, suitable elongated apertures 13 are provided so that the device 10 may be adjustably positioned relative to the flanges and securely held thereto by means of the bolts 14.

As shown in Figure 2, the heating attachment comprising an oval shaped body, has a central aperture corresponding to the internal diameter of the intake pipe. A pair of electrodes 16 pass through the body 10 and Serial No. 267,558.

are insulated therefrom by the bushings 17 made from suitable insulating material. Secured to the inner ends of the electrodes 16 by means of nuts 19 is a resistance heating coil 18, and one electrode is grounded, while the other electrode is connected to a Switch 20 and thence to the battery 21. The switch 20 may be positioned upon the dash board of an automobile or any other desired point.

In Figure 4 the attachment shown is similar to that described in Figure 2 with the exception that the heating element comprises a crimped wire 18 of high resistance instead of the heating coil 18.

In operation, when it is desired to start the internal combustion engine, the switch 20 is closed and the usual starting operations are performed. The heating of the fuel obviously will facilitate the starting of the engine and offers an especially desirable feature in cold weather. The electrical heating attachment is superior to other heating devices such as the use of the exhaust gases for preheating the fuel in the intake manifold. Vith the electrical heating attachment there is no danger of excessive heating and untimely explosions.

The foregoing disclosure is to be regarded as descriptive and illustrative onl and not as restrictive or limitative of the lnvention,

of which obviously an embodiment may be 1 constructed including many modifications without departing from the general scope herein indicated and denoted in the appendcd claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

A fuel vaporizing device for internal combustion engines comprising a generally ovalshaped fiat metal body adapted to be secured between the carburetor and the intake manifold of a combustion engine, said body being provided with a central intake opening therethrough for the passage of fuel to the intake manifold, apair of converging elec-- trodes transversely passing through the body and extending into the central opening, means for insulating said electrodes from the body, a crimpe-d wire having high electrical resistance attached to the electrodes and positioned in said central opening so that the intake fuel Will pass thereover, and elongated apertures in said body to enable. it to be adjustably positioned between the flanges of the carburetor and intake manifold.

In Witness whereof I have affixed my signature.

ERNEST KOSANEK.
