GAS MIXER Filed Nov. 19. 1927 Patented Dec. 31, A19129 UNITED STA TES PATENT- OFFICE WILLIAM R. BREWER, F DULUTH, MINNESOTA Gas MIXER Application filed ove-mber l the engine which inthe .instance illustrated is one of a six cylinder engine. 2 represents the carburetor spaced below the intake and connected thereto by means of a separable connection, the two parts being indicated at 2o 3 and 4 and intermediate of which is formed:

an helically shaped chamber 5. In this connection I haye shown one portion of the conv ne'ct-ion`as being formed integral with the intake'and the other portion attached to the carburetor; however these maybeseparable connections if desired. The opening into the manifold I prefer to. form slightly larger than the opening into the carburetor in which latter the ordinary butterfly valve 6 is installed.

Directly above this opening into the manil fold is formed integrally therewith, an.up standing tubular connection 7 in which are installed in any desiredmanner the spaced ball bearings 8 and 9. An axial hole is formed through the connection 7 withv the manifoldand Within this hole and the ball bearings is installed the supercharging fan, shaft 10 carrying upon its extreme lower end 4o i suction fan 11 which is preferably of propeller like construction and designed to forcibly suck wet gas from the carburetor and air through the'intake thereof when operated. Just above'this suction fan and within the opening into the manifold is a Wirev squirrel cage like mixing wheel 12 whichby rotation preventsany wet gas whatever passing into the manifold withoutbeing thoroughly agitated with the air and producinga dry gas,

within the chamber 5 the supercharging and- 19, 1927. serial No. 234,427.

Intermediate of the ball bearings 8 and 9 have Iillustrated an enlargement of the shaft 10 as at13 to act as a thrust bearing for said shaft, and the squirrel cage like agitator 12 and. suction fan`11 may be non-rotatably attached to the shaft inany'desired manner.

Now the rotation of the shaft 10 is accomplished by means of any desired form ofmotor indicated at 14, the lower end of the armature shaft of which is splined into the upper end of the shaft as indicated at 15, and

the lower end of the motor housing is provided-with. a cylindrical extensionl indicated at 16'for snugly fitting within the connection 7 and held therein as by the screw 17.

I have not illustrated the electric connection to' the motoras it is obvious that such may be of any desiredconstruction and controlled in any desired mannerv for example when used in connection with an automobile engine may be automatically operated by the.

starter switch or controlled independently y from the dash board.

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

1. In combination, a chamber installable .intermediate of the carburetor and intake manifoldv of an internal combustion engine, ashaft extending axially of and terminating within said chamber, a suction andcharging fan on said terminal of the shaft within the chamber, an open cage-like agitator on said` shaft adjacent said fan, a portion of said agitator'extending within the chamber and Ia portion'within the manifold, and means for rotating said shaft.

2. In combmatlon, amamfold, having a circular intake thel axis of which is at right angles to the longitudinal axis of the manilfold, a power shaft extending axially of and terminating within the intake, an enlarged circular chamber below the manifold and surrounding the free end of the shaft, a sucf tion and charging fan mounted upon the free end ofthe shaft within said chamber, an open cage-like agitator installed upon the shaft above the fan within the intake, part of the agitator being within the chamber and part I lwithin the manifold for the purpose described.

3. In combination, a manifold having a circular intake the axis of which is at right angles to the longitudinal axis of theimanifold, va power shaft extending axially of the intake, an enlarged circular chamber below the manifold and surrounding the free end of thev shaft, a lsuction and charging fan mounted upon the free end of the shaft Within said chamber, a spherically shaped agitator composed of a Iplurality of spaced ring like members mounted upon the shaft within the intake, part of the agitator being Within the chamber and part Within the mani# fold for the purpose described.

4. In combination, a connection intermediate of the carburetor and manifold of an internal combustion engine, said connection having a chamber therein, a rotatable shaft extending through the manifold With its free end terminating Within the chamber, a suction and pressure fan mounted upon the free end of the shaft, and open cage-like agitator carried by the shaft above the fan, a portion thereof being Within the chamber and a portion Within the manifold for the purpose described,

In testimony whereof I aiiix my signature. WILLIAM R. BREWER.
