Application filed October 22, 1919. Serial No. 333,734.

To alwkomitmay concem:

Be it known that I, ARCHIBALD W, GRIF- FIN, a citizen of the United States, and a resident of Holland, in 'the county of Lucas andl State of Ohio, have invented a certain new and useful Gasoline Vaporizer; and I declarethefollowing to be a full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usek the same, reference being had tothe accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification., f f

My invention .has for its object to provide a means for vaporizing gasoline to be used as a highspeed or low speed nozzle in a carburetor, or as a vaporizer or a priming nozzle Vto be used only at the starting of agasoline engine or vas a -vaporizing device for an auxiliary nozzle to be placed intermediate the carburetor and the engine, that' is, to be placed in the path of the vaporized or the semi-vaporized gases that pass from the carburetor into the engine. When used as ,an auxiliary nozzle or as a priming nozzle it may be placed in the4 manifold or it mayk be placed beside the nozzle of the carburetor. When usedl asia high speed' or low speed nozzle, it is placed in a carburetor either besideanother nozzle in the carburetor or it may be used in of a, carburetor.

The invention particularly has for'its,'ob-

ject to provide a means for heating the gasoline before it leaves, the nozzle or of heating not only the gasoline before it leaves the nozzle but also for heating the vaporized or the semi-vaporized gasoline that passes through the manifold. y

The invention may be contained in structures of diii'erent forms and to illustrate the practical application I have selected two or three modified forms of constructions ycon-A tainin the invention and shall describe them iereinafter. `The constructions f selected are illustratedin the accompanying drawings.

Figure I illustrates 'one form of nozzle and, particularly one form of the connection of the heating device with an external circuit. Fig. 2 illustrates a second form of nozzle and its connection with an external circuit. Fi 3 .is .a-vthird form of nozzle which may be used for heating not only the gasoline contained place of the ordinary nozzle c within the nozzle but also for heating the vaporized or semi-vacr1zedgasoliney that passes by the nozzle. 1g. 4 illustrates a fourth modification of the constructions illustrated'in the other figures. It illustrates a nozzle that may be used 1n a carburetor or that may be located 1n the manifold or in a part thereof.

Referring tothe figures lindicates'a part of the manifold or a part connected to the manifold. It illustrates in a conventional way a gasket that necting the manifold sired.

-The nozzlefis provided with an insulating tube 2.y The 'tube 2 may be made of insulating ber or it may be formed of porcelaln. One end of the insulating tube l2 is located in a threaded bushing 3 which'may be screwed into the gasket l. It contains' a resistance wire 4 that may be. made in the form of a spiral which abutsl at its lower end. against the bushing 3. The spiral 4 is slightly compressed when the cap 5 is placed on the upper end of the bushing 2. This causes the spiral 4 tol complete an electric circuit with the cap 5f and the bushing 3. By this arrangement gasoline may be brought directly in Contact with an electrically heated wire which operates instantly to change the gasoline into gas that may be with the engine, if demaybe used for conf' into the engine or mixed with the air in the'y passageways and cylinders of the engine to produce-an explosive mixture. Thus I have. produced by my invention a means for readily starting a car in ,any kind of weather. f

vvA .pipe 6 may be connected with the bushing 3A and also with the source of gasoline supply, while the cap 5 may be provided with the passageways 7 that communicate with the interior of the tube 2. By this arrangement the gasoline ,may be drawn from' the source of supply and through any suitable regulating valve into thepassageway leading to the engine, such as into the manifold ofthe engine. l The gasoline will be drawn from the source of z suppl by the suction produced in the engine. en the 50 form of The circuit whereby the spiral 4 may be heated by an electric currentlnay be Vconipleted through avrod 8 that extends into the passageway leading from the carburetor to the manifold. The: rod 8 lmay extend through the manifold wall either from the top or the side of the manifoldf in order to make contact with the cap `7. In the-form of thel invention shown in Fig. Y1, the rod 8 extends through an insulating bushing 9 which is threaded into the gasket 1. The upper end of the rod 8 forms a binding post, it being provided with a thumb nut 10 and insulating washer 29 whereby connection may be made with a suitable wire 11. The'current passes through the wire 11, the rod 8, the capV 7 and the spiral 4 which is groundedat the pointof its contact with the bushing 3. y

If desired, the tube 2 may be extended up through the gasket 1 and'contact may be made direct with the spiral 4 by means of 'a pin 12 that extends down through the tube 13 to near the outlets 14 that correspond withl the passageways 7 inthe form of construction shown in Fig. 1. The circuit connections in the form of the invention shown in Fig. 2 are substantially the same as that in the form of the invention in Fig. 1the spiral 4 being grounded at the point of its contactV with the bushing 3. y

A further modification is shown in Fig. 3 wherein the spiral 15 is placed on the outside of the insulating tube of fiber or porcelain 16. One end of the spiral 15 is connected with the ring 17 located on the upper end of the tube 16 yand the other end is connected with the ring 18 located 'on the lower end of the tube 16. When the cap is placed in position on the tube 15 it is placed in contact with the ring 17 and also when the tube 16 is inserted inits position in the bushing 3, the ring 18 makes contact -withthe bushing 3, thus the circuit is completed through the rod 8 to the ground that is made by the contact between the ring 18 and the bushing 3.

In theforms of the structures illustrated in Figs. 1, 2 and 3, the tube is inserted from lbelow1 into the supporting structure and into the passageway of the vapor or gas. V In the constructions illustrated in Figs. 1 and 3, the circuit is completed through the rod 8 which is -inserted from any suitable point into the passageway and so as to make contact with the cap 5. In the form of construction illustrated in Fig.y 2, the circuit is completed by the pin 12 which extends down to the spiral 4 through the tube. In the form of construction illustrated in Fig. 4 the tube may be made of metal and is placed in the supporting structure by attaching it from above.

The tube 19 which may be formed of metal is threaded into the wall of the manifold or into the wall of the carburetor indcated at 20. The tube provided with a channel 21 or other opening located at its lower edge which registers with the opening 22-fo`rm'ed in the wall of the carburetor or the manifold or` part of the manifold, wherebythe gasoline may enter into the tube 19. It is drawn out through the passageways 23 by a` suction Kof the engine in the manner well known, A slender insulating rod 24 having a central core 25 is supported in a threaded bushing 26. The rod 24, when the bushing 26 is placed in position in the supporting structure, extends into the tube 19. A wire 27 wound in the 'form of a spiral about the rod 24 is connected to the upper end of the core of comparatively large wire 25 and extends downto the bushing 26. The circuit i's rv'completed through the wire 11.' The wire 11 may-be clamped between the thumb nut 10 'and the lower end of the rod 24, and thus connected to the core25.

In this form of construction the gasoline enters thel passageway 22 and substantially fills the tube. 19 andY thus cornes in contact with the wire27; It will thus be heated when fan electric current passes through the wire 27. By the arrangement shown in the structures illustrated in the drawings, the

ga'solinefis heated and vaporization is assisted by Va very small current `'such as two or three amperes, by reason of the fact that the gasoline cornes in direct contact with the wire. kIn the form of structure ,illustrated in Fig. 3 the gasoline in the tube 16 is heated by the wire 15 located on the outside of the tube, and if the tube is placed in the path of the vaporized or the semi-vaporized gasoline, as from a carburetor, it is heated by direct/contact with the wire 15. Also any gasoline that may flow out of -the openings of andrdown over the tube islikewise heatedI by direct contact with the wire and immediately changed into a vapor.

The tubes 2, 16, 13 and 24 may be secured in the bushings 3 and 26 by cement or in any other suitable wayfor connecting fiber or porcelain tubes to a metal bushing. Also the pin 12 may be secured in the tube 13 by cementing them together with a suitable cement or by a suitable packing of anyrform. Also theresistance wires4, `15 and -27 may be straight wires in place of being formed in the shape of a spiral. The spiral, however, is a preferred form as it operates elastically to make contact with the parts between which it is located. This is particularly true of the structures illustrated in ply,

1,446,087 n f a gasoline through thefnozzle and connected to the source of electric current supply.
