I NVENTOR ATTORNEY mama UNITED STATES CARL A. PETERSON, 0F

SUPERIOR, WISCONSIN.

GAS-MIXER.

Application filed May 13,

T 0 all whom it may concern:

Be it known that I, CARL A. PETERSON, a subject of the King of Sweden, residing at Superior, in the county of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Gas- Mixers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to gas mixing devices and has special reference to such mechanism used in connection with the gas supply of an internal combustion engine which is received through a manifold or feed pipe leading from a carbureter.

The principal object of the invention is to produce a practical and effective device for assisting in the more thorough mixing and agitating of the gas as it passes through the feed pipe from the carbureter to the engine. Another object is that of simplicity of construction and durability of the device. Still other objects and advantages of the peculiar construction will appear in the further description of the invention.

I am aware that many different forms of both rotative and fixed devices have been employed for this purpose, but believe that I have discovered a peculiarly shaped mixer and associate parts that will give exceptionally good results; in fact the same has been thoroughly tested, proved to be practical and very satisfactory.

In the accompanying drawings forming part of this application and in which like reference characters indicate like parts:

Figure 1 is a top plan view of my complete mixer ready for installation intermediate of the two parts of the ordinary feed pipe adjacent the carbureter of an internal combustion engine;

Fig. 2 is a central transverse section through the assembled parts of a feed pipe having my mixer installed therein and shown in side elevation;

Fig. 3 is an elevation of the mixer taken at right angles to Fig. 2;

Fig. 4 is an elevation of the rotatable plate or blade before being shaped about its supporting sleeve; and

Fig. 5 is a perspective view of the sleeve or hollow shaft to which the blade is rigidly fixed when assembled.

1 represents a thin fiat washer or gasket which forms the main support of the mixer and is installed intermediate of the simi Specification of Letters Patent.

1920. Serial No. 381,024.

larly shaped spaced portions of the two ends of the feed pipe, when assembled, as lllustrated in Fig. 2 of the drawings. This gasket has formed in the center thereof a circular hole 2 which is equal in diameter to the interior of the feed pipe and diametrically across which and preferably integrally formed with the gasket is an upwardly arched support 3 which has fixed 1n the center thereof the pin or spindle 4 for rotatably supporting the mixer. The rotative portions of the mixer comprise preferably the elongated sleeve 5 which is slightly shorter in length than the pin 4: and held thereupon against dislodgment by a suitable collar 6, there being provided ample play intermediate of the end of the sleeve and the collar to insure ready and free rotation of the mixer.

7 represents the mixing blade which is a single piece of sheet metal, the lower end being semi-circular in form as at 8, and the upper end square or straight as at 9. In construction there are three transverse cuts 10, 11 and 12 made through the blade and spaced substantially equi-distant from the upper square end toward the lower round end. The uppermost division 13 of the plate thus cut is bent outwardly to form a semi-circular hearing about the sleeve 5, while the intermediate portion 14 is bent outwardly in the opposite direction to form a like bearing on the opposite side of the sleeve, and the lower section 15 is bent to aline with the section 13, thus forming a circular opening centrally and longitudinally of the blade for insertion of the sleeve.

There is a semi-elliptically shaped opening 16 within the plate beneath the portion 15 which permits of the free ends of the semi-circular portion 8 of the blade, which is divided or bifurcated at 18, being bent in a curved form at right angles to the flat face of the opposite end and snugly fitted against the sleeve 5, the ends of the plate thus formed extending in radially opposite directions from the sleeve as shown clearly in Fig. 3 of the drawings.

lVhen the blade is thus assembled about the sleeve 5 it is securely soldered, brazed or welded thereto to make a single unit which rotates by the energy imparted to the curved ends of the blade by the upward passage of the gas in the pipe on its way to the cylinders of the engine.

The upper portion of the blade is straight and its edges parallel with the sleeve so that when the plate is rotated by the action of the gas as heretofore stated, said upper portion will impart only centrifugal motion to the gas, while the lower portion thereof receives motion from the gas and is actuated thereby.

It will be noted that the lower ends of the plate are not spirally. twisted, but are curved outwardly on an axis transverse the axis of the sleeve.

Suitable oil holes are indicated at 19, through which suffieient lubricant is received from the gas mixture, it being known that such contains slight quantities of oil.

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

1. A gas mixer of the class described, comprising a support having a spindle securely fixed thereto, a combination propeller and fan-1ike blade rotatably carried upon the spindle, a portion of said blade on either side of the spindle being straight and parallel therewith, while the other portion is bifurcated and each half thereof curved outwardly in radially opposite directions from the spindle.

2. A gas mixer of the ClflSSnClGSCIlbGd comprising a support having a spindle securely fixed thereto, a sleeve rotatably mounted upon the spindle, a rotative blade fixed to the sleeve, the approximate half of which, adjacent the free end of the spindle, extends radially therefrom in opposite directions, and, for a distance longitudinally thereof, parallel therewith, while the bifurcated pdrtions of the opposite half are curved in opposite directions from the spindle, substantially as described.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.

vCARL A. PETERSON.
