1 Claim.

This invention relates to new and useful improvements in carburetor air intake and vaporizers and has particular reference to a device for introducing the air into the carbureter, mixing this air with the volatilized gas or fuel mixture, and to further use a turbulent condition which will complete the mixture of air and gas.

A further object is toproduce a device of this character which may be employed with the ordinary carbureter or with the ordinary internal combustion engine without materially altering its construction.

A further object is to produce a device of this character which is economical to manufacture.

A still further object is to produce a device which will automatically control the amount of air which may be drawn into the device.

A still further object is to produce a device wherein heavier particles of dust and dirt will be filtered from the inrushing air.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a vertical cross-section of my device as the same would appear in use with a conventional carburetor.

Fig. 2 is a cross-sectional view taken on the line 22 of Fi 1.

Fig. 3 is an end view looking in the direction of the arrows 33 of Fig. 1.

And Fig. 4 is a cross-section taken on line 44 of Fig. 1.

In order to provide a suitable explosive mixture for an internal combustion engine it is necessary that the quantity of air be mixed with the quantity of gasoline vapor and the same delivered to the cylinders of the engine. It is important that this air be controlled as to volume and also that a mixing process take place. This mixing process is best accomplished by introducing in the line of travel a plurality of wires which break up the stream in passing before the air and gas reach the manifold.

Referring to the drawing the numeral 5 designates an ordinary carburetor connected to the gas line 6. The outlet of this carburetor is shown at 1 and connects to a standpipe 8 having a venturi 9, and a port I l communicates with the carburetor at a point below the venturi.

Above the venturi I employ the ordinary butterfly valve l2, which functions in the usual manner. A portion of the manifold is shown at I3 and is connected to the standpipe 8 by the usual flanges and bolts I4. Secured between the flanges of the standpipe 8 and the manifold I3 is a vaporizing or agitating unit comprising a plurality of bent wires l6. Connected to the lower portion of the standpipe is a horizontal section I! having a flared funnel like end l8.

Surrounding this funnel like end is a casing IQ of larger diameter than the large end of the funnel IS.

A second funnel 2| has its large end connected to the free end of the casing l9 and has its small end extending into the large end of the funnel I8. This arrangement permits the free passage of air through the ports 22 formed in the casing 19 and around the funnel H! as indicated by arrows in this figure.

A sliding tubular member 23 is telescopically carried on the casing l9 and has an inwardly projecting cup shaped portion 24 slidably mounted on a rod 26. This rod carries a spring 21 which presses against a spider 29 formed upon the cup 24 and has its opposite end bearing against a spider 3| carried in the end of the horizontal pipe l1. It will be noted that a tapered valve 32 extends into the cup 24 and is mounted upon the rod 26.

The result of this construction is that when the engine is running air will be drawn through the ports 22 and around the end of the funnel l8, thence through the venturi, thence upward through the Wires l6, where the air stream will be broken up together with the gasoline vapors mixed therewith, and an efficient explosive mixture will result. Should the combined area of the ports 22 not be great enough, then the suction of the engine will draw the telescopic member 23 against the tension of the spring 21 thus allowing air to enter the cup 24 past the valve 32, which air will follow the course of the arrows within the cup.

It will thus be seen that I have produced a device which will accomplish all the objects above set forth, and it is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes relative to the size, shape, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim:

Having thus described my invention, I claim:

A device of the character described, in combination with a carburetor, a standpipe attached to the carburetor and communicating therewith,

a manifold connected to said standpipe and communicating with an internal combustion engine, an agitating element positioned between said standpipe and said manifold, a horizontal extension connected to said standpipe, a funnel secured to said extension, a casing surrounding said funnel, ports formed in said casing, at a point adjacent to the connection of said funnel with said horizontal port extension, and a second funnel sealed to the end of said casing, having its small end projecting into said first mentioned fun-
