MIXER.

Specification of Letters Iatent.

. Patented July 22, 1919.

Application filed February 18, 1919. Serial No, 277,738.

To all whom it may concern:

7 Be it known that I, JOHN H. DENNER,

citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Mixers for Internal-Combustion Engines, of which the following is a specification.

My invention is an improvement in mixers for internal combustion engines, and has for its object to provide a device of the character specified adapted to be arranged between the carburetor and the engine in the intake manifold to thoroughly break up and revaporize the charge drawn toward the engine from the carbureter, and to insure the more perfect combustionand increased power with the same amount of fuel.

In the drawings:

Figure 1 is a sectional view of the connection between the carbureter and the intake manifold, with a carburetor in lowered position;

Fig. 2 is a similar view with a carbureter arranged in elevated position;

Fig. 3 is a perspective view of the mixer detached Fig. 4 is a front view of the coil;

Fig. 5 is a perspective view of the shaft;

Fig. 6 is a perspective view of a modified construction of coil.

The present embodiment of the invention is shown arranged within the intake mani fold 1 which connects the carbureter 2 with the combustion chamber of the engine 3.

The improvement comprises a gasket at corresponding in shape to that gasket which is arranged between the abutting flangeof the intake manifold and the engine, for sealing the oint at this point, the said gasket being adapted to replace the usual washer. This gasket 4: has a bar 5 extending diametrically of the opening in the same,

washer 10 which may be also of wire or of any other suitable material, and the coil is wound spirally, all of the coils of the spiral lying in a plane perpendicular to the shaft.

By means of the ring 10, which may be formed from the material of the coil or may be separate, the coil is connected to the reduced end 8 of the shaft, the ring 10 being slipped over the reduced end, which is engaged by a keeper pin 11 to hold the parts in place. This coil will be vibrated by the current of air caused by the suction of the engine, as it draws in a charge of fuel, and the vibration will thoroughly break up the fuel and thoroughly mix it with the air, asiurilng the complete revaporization of the The vapor passes on into the engine and because of its thoroughly revaporized and mixed condition there will be complete combustion and increased power on the same amount of fuel. The coil 9 is of sutficient external diameter to approximately fill the bore of the intake, that is, to extend from wall to wall thereof and all of the charge that is passed into the engine must pass through the spirals of the coil, being thus thoroughly broken up and intermixed with the air. The very rapid vibration of the coil due to the passage of the air carrying the fuel will thoroughly break up the heavy weight gases from the carburetor, making them easier to ignite and insuring quicker combustion.

In Fig. 6 is shown a modified construction wherein the shaft 12, which is connected at one end to the bar 13 of the gasket 14, has at the other end a long reduced portion 15. A coil 16 is mounted on this reduced portion adjacent to the shoulder formed between the reduced portion of the body of the'shaft and the sleeve or arbor l7 encircling the reduced portion beyond the coil.

A second coil 18 is arranged at the end of the arbor on the reduced portion and all of the parts are held in place by a cross pin as shown. This construction is especially adapted for a certain type of engine. The device is easily applied to existing cars, either of the low down carbureter type where the feed is by gravity, or the high up type, where the feed is by pressure. As shown in Fig. 2, the gasket 4: is arranged between the carburetor nipple and the ined to be arranged at the axis of the manifold, a spirally Wound coil connected with the shaft and extending between the same 10 and the Wall of the manifold and with its turns lying in the same plane and in a plane perpendlcular to the shaft, said 0011 belng' of a diameter corresponding approximately to that of the cross section of the manifold, for the purpose specified.
