'FREERICK F. WIESE, OF ST. LOUIS, IVIISSOUR.

GASEOUS-FUEL MLK-ER.

Application filed July `9,

To all l207mm it may concern.' Y f Be it known that I, FREDERICK F. lVIEsn, a citizen of the United States, and resident of St. Louis, Missouri,have invented certain new and useful Improvements in a Gaseous-Fuel Mixer, of which the following is a specification.

This invention relates to improvements in a gaseous fuel mixer for internal combustion eng'ines and has for its object a. mixing means of a rotatable nature placed in the manifold at the entrance of the intake of the engine block. The mix-ing means comprising a rotating member axially mounted 3 in a sleeveand a mixing element to be placed in rotation by the suction created by the manipulation of the pistons.

A further object of my invention is to construct a simple device composed preferably of a ring in which is axially mounted a three winged rotating member constructed of gauze or reticulated material, the wings being so positioned as to prevent and overcome a. dead center, one of said wings being at all times in a position to be placed in operation by the suction of the engine.

Figure l is a side elevation of an internal combustion engine showing the application of my invention in the manifold.

Figure 2 is a detailed edge view of my improved mixer.

Figure 3 is a side view of the same.

Figure 4 is a vertical, central, sectional view of the same. y

Figure 5 is a horizontal sectional view taken on the line 5-5 of Figure 4.

Figure 6 is a detailed perspective view of my improved mixer.

Figure 7 is a detailed perspective view of one of the wings made use of in carrying out my invention.

Figure 8 is an enlarged detailed horizontal sectional view of the rotating member.

Figure 9 is an enlarged detailed horizontal section of a portion of one of the wings showing the structure and position of the same.

Figure 10 is a horizontal sectional view of a portion of the engine block and manifold attached thereto with my improved mixer attached and placed in position.

block to the carburetor which is attached to the end, 14.

The manifold is attached in the usual well known manner to the engine block so that its intake ends, l5, register correctly with the intake port, 16, in the engine block and through which the gases are directed to the proper cylinders. In the intake end, l5, of the manifold is placed my improved mixer which consists of a Vring or rim, 17 constructed of a size to snugly fit into the manifold intake as that shown in Figure 10. In this rim, 17, is placed a rotating mixing member, 18, consisting of three members, 19', the same when placed and fitted 'together virtually forms a propeller, each wing being arranged at an angle of l20degrees, thereby equally balancing the same. These three members are formed with a peripheral channeled rim, 20, in which is firmly clamped a sheet of gauze or reticulated material, 21, with the center portion of the rim andimaterial bent out forming a support, 22, which i fits snugly over a shaft or supporting axil, 23. This shaft or axil is provided at its bottom end with a needle point, 24, which fits into a corresponding seat, 25, thus forming what is termed a pivot point journal. The upper end, 26, of the shaft or axil is supported in the bore, 27, formed in the rim, 17.

The members which constitute the wings of the rotating mixing member are supported in any desirable well known manner to the supporting shaft and the outer edge orr periphery of the adjoining wings are firmly connected together by brazing, welding, or soldering, which is found to be the best method for rigidity and durability.

By the position of the wings ofthe rotating member, it provides an equal balance in the same and one or more of the wings are at all times in such position as to cause the same to rotate during suction and pulsation of the operating pistons.

On account of this structure the gas which is sucked into the manifold from the carburetor is thoroughly whipped as it passes from the manifold into the intake, thus thoroughly mixing the gas, which it has been found by practical experience, the gasoline from which the gas is created is comprised of per cent coal oil, 2O per cent water, and 15 per cent gas. This proportion when passing through the rapidly rotating mixing member is mixed up and divided into each IUS 4cylinder a uniform mixture Which produces a better' eiect and causes the engine to operate more freely and evenly and more mileage is obtained from a gallon of gasoline than when the mixture is permitted to enter the intakes direct from the carburetor Without the application of my improved mixer.

These devices are placed in the manifold at each intake port so that each cylinder is provided With the equal amount and same mixed gases. V

Having fully described my invention, what l claim is:

l. A gaseous fuel mixer comprising a rim, an equally balanced threewiirg` mixing device axially supported in the rim, the same to be inserted at the intake port of the engine block, substantially as specified.

2. A mixer of the character described comprising` a rim, a rotating member axially mounted therein, said rotating member composed of three sections located at equal distances apart and equally balanced, and each section provided With gauze, substantially as specified.

3. A. device of the character described comprising` a rim, a pivot shaft supported in said rim, three Wings Yradiating` from said shaft and equally balanced thereon, said Wings comprising` a peripheral rim in which is supported a strip of reticulated material and through which the gases must )ass in its travel from the manifold to the cy inders of the engine, said wings and shaft placed in rapid rotation by the pulsation of the operating engine, substantially as specified.

4. A device of the character described comprising a rim, a three Winged propeller, a pivot shaft supporting the propeller, each Wing of the propeller composed of a peripheral rim to Which is secured a strip of gauze, each Wingbeing so connected as to make a double Wall of gauze through which the gases must pass in order to enter into the engine chamber, said device When assembled being' placed in the mouth of the intake port of the engine block substantially as specied.

In testimony whereof l have signed my name to this specification in presence of two subscribing Witnesses.
