Exhaust supercharger

Claim 2

An exhaust supercharger apparatus intended for mounting to the exhaust pipes and air cleaner and water pump of a conventional internal combusion vehicle engine, the apparatus comprising, in combination: an air cooled muffler having an inlet pipe adapted to be connected to the exhaust pipes of said engine, and an outlet pipe; a sound reducing muffler having an inlet port and an outlet port; an exhaust pipe adapted to connect said outlet pipe of said air cooled muffler to said inlet port of said sound reducing muffler; a water cooled muffler having an inlet pipe and an outlet pipe; an exhaust pipe adapted to connect said outlet port of said sound reducing muffler to said inlet pipe of said water cooled muffler; a vapor trap having an inlet and an outlet; a pipe adapted to connect said outlet pipe of said water cooled muffler to said inlet of said vapor trap; an air-exhaust mixing chamber including means for mixing fresh air with exhaust gasses, said chamber having an inlet and an outlet; a pipe connecting said outlet of said vapor trap to said inlet of said air-exhaust mixing chamber; an elongated cylindrically shaped filter having an inlet and an outlet; a pipe adapted to connect said outlet of said air-exhaust mixing chamber to said inlet of said filter; a pipe adapted to connect said outlet of said filter to an inlet tube of said air cleaner of said engine; a water reservoir having an inlet port and an outlet port; a water jacket formed integrally with said water cooled muffler and having an inlet and an outlet; and water carrying tube means interconnecting said water reservoir to said water cooled muffler and to said water pump for maintaining water flowing through said water jacket.

Claim 3

The exhaust supercharger apparatus as set forth in claim 1 wherein said water cooled muffler comprises an inner muffler of a rectangular cross-sectional configuration extending completely between said inlet pipe and said outlet pipe; a watertight jacket completely surrounding the exterior surface of said inner muffler and spaced outwardly therefrom; a watertight compartment defined intermediate the interior of said jacket and the exterior of said inner muffler; an inlet port and an outlet port affixed to opposite ends of said water jacket and connected respectively to said water inlet pipe and said water outlet pipe for ingress and egress of water through said watertight compartment for cooling said inner muffler; and a multitude of longitudinally spaced apart outwardly transversely extending cooling fins affixed to said water jacket to assist in the cooling of said water jacket.

Claim 4

The exhaust supercharger apparatus as set forth in claim 2 wherein said air-exhaust mixing chamber is characterized by: a cylindrical vertically extending housing having cylindrical side walls, a flat bottom surface, and an open top surface; a chamber defined interiorly of said wall surfaces above said bottom surfaces and opening out of said top surface; a flat disc shaped member having vertical veins extending radially outwardly from the periphery thereof disposed inwardly of said compartment concentric therewith to define a veined impeller member; an opening centrally of said housing bottom surface in communication with said compartment; an electric motor mounted to the exterior of said bottom surface concentric therewith and having a shaft extending vertically upwardly therefrom passing through said bottom surface central opening and affixed to said veined impeller member to effect the rotation thereof in said compartment; a circular disc-shaped cover member adapted to restingly fit on said compartment top surface to close said compartment; a ring shaped seal member interposed intermediate the top edge of said housing side wall surfaces and said cover member for sealing said compartment in an airtight manner; a clamp ring member adapted to pass over the peripheral edges of said cover member and engage a top edge portion of said housing completely about the side walls thereof for removably lockingly retaining said cover member and said seal ring to said housing to close said compartment; a horizontally disposed hollow open ended ram tube member having an oblong cross-sectional configuration and having an inlet end and an outlet end, said ram tube extending radially outwardly from the side wall of said housing with said outlet end in communication with said housing compartment for introducing fresh air thereinto; said outlet from said chamber consisting of a cylindrically shaped outlet pipe having one end affixed to an opening in the side wall of said housing spaced about ninety degrees circumferally from said ram tube with said pipe extending radially outwardly therefrom in a horizontal disposition; a diverter plate member affixed to an interior of the housing side wall projecting angularly into said chamber, the diverter plate being of a generally L-shaped configuration having the base thereof extending vertically and affixed to the interior of the chamber side walls in a position adjacent said outlet opening and on a side of said outlet opening spaced furthest from said ram tube, the leg portion of said diverter plate extending outwardly into the path of said outlet opening in the general direction of said ram tube; said inlet to said chamber consisting of an opening in the side wall of the housing spaced equal distance circumferally from said outlet pipe and said ram tube on the opposite side of said veined impeller member; a box-like hollow receptacle affixed to the exterior of said housing side walls completely surrounding said inlet opening and extending radially outwardly therefrom and having an inlet port; a cylindrical pipe having one end affixed to said receptacle inlet port with the opposite end extending radially outwardly therefrom relative to said chamber housing; a pair of baffle plate members extending parallel to each other into said receptacle compartment with said baffle plates being spaced from each other and with one baffle plate extending at least partially in front of said housing inlet opening and with the other baffle plate extending at least partially in front of said receptacle inlet port so as to baffle incoming exhaust gasses to reduce the pressure thereof.
