Abstract:
A screen and a stationary screw propeller are arranged in round chambers between the carburetor and intake manifold of an internal combustion engine of an automobile, for example, to substantially increase the efficiency and gasoline mileage thereof.

Description:
BACKGROUND OF THE INVENTION 
     Heaters and vaporizers have been proposed for use in carburetors to improve the efficiency thereof, but most are complicated, and require special tools to make, as well as to install. Also, such proposals fail, due to the nature of the apparatus causing the formation of solids on the internal equipment that is exposed to heat and the gasoline-air mixture. 
     The main object of this invention is to provide a gasoline miser that is simple and inexpensive to make and install in existing internal combustion engines, as well as one that is self-cleaning and not subject to fouling in use. 
     SUMMARY OF THE INVENTION 
     A heavy metal fine screen and a stationary screw propeller are provided in round holes between the carburetor outlet and intake manifold of an auto engine to first break up into super fine particles, the air-gasoline mixture leaving the carburetor, and then swirl the resulting super fine air borne particles of gasoline downwardly and outwardly into the intake manifold inlet chamber of the engine. Thus, the gasoline is fully vaporized and mixed in the air stream, providing a mixture that is highly combustible and efficient in the engine. The engine life is increased, mileage is increased, and pollution decreased. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is an exploded view in perspective of a gasoline miser embodying the invention, with parts shown of a carburetor and intake manifold; and 
     FIG. 2 is a view in vertical cross-section of the miser in place. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in the drawings, a bottom section 10 of the miser 12 is mounted on a gasket 14 on the top of intake manifold 16 of an internal combustion engine 18 having a carburetor 20. The manifold 16 is provided with threaded sockets 22, 22 on either side of a central inlet chamber 24, leading to the inside of the manifold 18. The bottom section 10 is hollow except for ribs 26 and 28 which support a cylinder 30 having a cross support 32 for a bolt 34 from which is suspended a stationary screw propeller 36 having a plurality of blades 38, in the round chamber 24. The ribs 28 are provided with slots 40 having knockout tabs 42 in one side of the bottom thereof for aid in aligning the various gaskets with screw bolts 44, 44 which hold the parts together. 
     A heavy metal fine screen 46 is mounted on the bottom section 10, having slots 48, 48 matching slots 40, 40 in the section 10. A rim gasket 50 is disposed between the screen 46 and a top section 52 of substantial thickness having a central hole 54 and slots 56, 56 provided with upper knockout tabs 58. A gasket 60 having slots 62, 62 and a central hole 64, is clamped between the bottom of carburetor 20 and the top of section 52, so that the outlet 66 of the carburetor 20 matches the holes 64 and 54 of the gasket 60 and top section 52. The parts of the miser 12 shown in FIG. 1, are clamped together, FIG. 2, between the bottom of carburetor 20 and top of intake manifold 16 by the screw bolts 44, 44 which are threaded to the sockets 22, 22. 
     In operation, the fine screen 46 breaks up into super fine particles, the gasoline in the air-gasoline fuel mixture leaving carburetor 20 outlet 66, and then is swirled outwardly into the manifold inlet chamber 24, by the stationary screw propeller 36 blades 38, completing vaporization of the gasoline in such fuel mixture. 
     Greater combustion in the engine 18, of the fuel mixture is thus achieved, along with much better mileage, as much as 75%; less pollution; and an increase in the engine life. The device is easy to install, since it fits between the carburetor and manifold; and is safe in use. While the invention is shown with a single barrel type of carburetor, it can be adapted for 2 and 4 barrel carburetors as well. 
     The screen is composed of a bronze wire mesh, but may be made of metal wire coated or plated with a catalytic agent such as platinum. Where the case warrants, platinum itself may be used.
