High efficiency snow thrower

A material throwing machine, comprising:

• a housing having a partially cylindrical rear surface and an open front;
• an auger member comprising a cylindrical member rotatably mounted within said housing extending across said open front of said housing and
• a strip affixed to said cylindrical member to project radially from an outer surface of said cylindrical member and having opposite segments extending in from each of opposite ends of said cylindrical member in opposite handed helical windings about said cylindrical member, said strip segments rotating in close proximity to said cylindrical rear surface of said housing, an impeller pocket joined to said strip segments intermediate the ends of said cylindrical member whereat said opposite handed helical in segments meet, said impeller pocket configured to receive material advanced along said cylindrical member inwardly to said impeller pocket, and slinging material radially outwardly by rotation of said impeller pocket by rotation of said cylindrical member;
• a deflector shield mounted to said housing at the center thereof shielding said impeller pocket and having a radius inside face within which said impeller pocket rotates which is also confined by said cylindrical rear surface of said housing;
• a discharge chute located directly above said impeller pocket to receive snow;
• a rotary drive rotating said cylindrical member at a sufficiently high rate to cause material fed into said impeller pocket to be discharged from said machine by being slung from said impeller pocket directed upwardly therefrom.
