To all whom it may concern:

Be it known that WILLIAM WHEELER, a citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings and State of New York, has invented certain new and useful Improvements in Electrical Fuel-Vaporizers, of which the following is a specification.

i This invention relates to means for va orizing liquid fuel for use in internal-com ustion motors, and it comprehends means enabling'ele'ctrical current, in conjunction with a resistor element, to furnish thede sired liquid fuel, in its passage to the manifolr or engine intake, may be raised in temperature and'gasified. In practising my invention I have 'plaoedthe resistor in the passe e between the carburetor and the engine, w ereby the'mixture of fuel and air 26 which issues from the carbureter is. caused totraverse a heat'passage, in order that in such transit the fuel and air may become thoroughly mixed through the action of heat in volatilizing the fuel. The fuel conductingdevice, which may also support the resistor, may be divided up into a number of'small ducts, each containing a resistor strand or length, in orde that the volume of mingled fuel and air passing throu h each of these ducts may be relatively snia l, to permit a more thorough the passing ffnel charge by is heat generated.' Alsoby means of a rheostat or other devices for varyin the amperage, I am enabled to regulate t e degree of heatgenerated in the resistor, and thus to govern the developed temperature according to. the requirements.

Preheating means for hydrocarbon mixtures, while well known in gas engine practice, have hitherto been limited toservlce in jacketing the carburetor, or the pipe leading therefrom to the engine, and have not been capable of communicating heat from within the volume of mixture in what me be termed the critical point of its flow, which is just before the fuel enters the engine, to revent a fall in temperature in the trave of the fuel from the carburetor to the engine.

By preheating means such as are comprised in my invention, gasolene may be rendered more serviceable than otherwlse, and heavier hydrocarlmus, such as kerosene and alcohol, may be enerated into gas and also thoroughlyblen ed with their attendnetration of ant quotas of air, to thus enter the cylinder as an efficient explosive mixture.

Other features and advantages of my said invention will hereinafter appear.

In the drawing:

'Figure 1 is a sectional view showing a.

portion'of an engine manifold, in connection with a carbureter, and illustrating a form of my improved electrical vaporizer;

and Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.

In the exam le of m invention shown in the drawing, liet 1 in icate a conventional form of a carburoteryand 2 a portion of piping or passage, which may represent a pipe leading directly to the engine intake, or may form a part of an engine manifold. Within the passage 2 I have shown a form of vaporizing device 3, represented-as the frustum of a cone, which tapers in the direction of the engine intake, and whose base is pr0- vided with a flange 4 that is seated between the respective flanges 5 'andfi of passage 2 and carburetor 1, being secured thereto as by bolts 7. In this or other suitable manner the vaporizer may be localized in operative relation with the carburetor to gasify the mixture flowing to the engine.

he vaporizer 3 is shown as provided with a series of lengthwise arranged a ertures 8 which serve the purpose of clivi ing up the mixture into a number of small columns, said lengthwise apertures also having a series of laterally or radially communicating orifices which extend therefrom to the outer surface of the vaporizertoward the inner or. tapering end thereof. Thus the mixture, which is changed to a gaseous state in the vaporizer, issues both from the lengthwise apertures and from the lateral orifices as gas'in its passage to the engine. The lateral orifices serve the purpose of providing a more free flow of the formed gas, whose efllux is expedited in this manner.

- The conical form of the vaporizer, in co 0 oration with the cylindrical form-shown thepassage 2, affords an increasing area and fro through the series of said apertures, and its terminals secured in binding posts 10 where it is included in an electrical circuit 11, having a source of electrical energy 12.

The resistor strands or lengths within the apertures 8 are suitably insulated from each other, as by constituting the vaporizer device of material which is a non-conductor of electricity. Said resistor strands or lengths, which lie within the series of apertures 8, obviously must not fill said apertures, because clearance is required within the apertures for the passage of the fuel.

Variation of temperature generated in the vaporizer is desirable and may depend in degree upon the temperature of the atmosphere or the character of the fuel in use, and I therefore provide current regulating means such as a rheostat 13, whereb the heat to be generated may be control ed.

I have found in practice that by heating the resistor to incandescence, and presenting its strands or lengths to contact with the fuel passing through the vaporizer device, said fuel, which may have left the carbureter in atomized condition, become vaporized and thoroughly blended with the air in which it is suspended; the device servin in fact as a combined mixingphamberan va orizer.

ariations'may be resorted to within the spirit and scope of my said invention, and

parts thereof used without others.

2. A vaporizing device to be located .within the manifold of an internal combustion engine, and spaced therefrom, said device having a series of lengthwise apertures for fuel flow, each surrounded with insulating material, a continuous resistor threaded back and forth through said apertures, and an electrical circuit therefor, whereby the temperature of the passing fuel may be raised.

3. A conical vaporizing device to be located within the intake manifold of an internal combustion engine, and spaced therefrom, said device having a series of length Wise insulated apertures for fuel flow, and a series of radial orifices arranged toward the tapcrin portion of said device, a resistor threa ed back and forth through said lengthwise apertures, and an electrical eir cuit therefor, whereby the temperature of the passing'fuel may be raised.
