Snow thrower auger with replaceable paddle

Claim 2

A snow thrower auger, comprising a cylindrical base portion, spiraled flights extending on said base portion for moving snow axially along said base portion to discharge location on said base portion, a paddle extending radially outwardly on said base portion at said discharge location for engaging the snow and impelling it away from said auger, said paddle being a discrete piece distinct from and removably secured relative to the remainder of said auger and being replaceable in said auger separate from said remainder of said auger, releasable fastening means connecting said paddle with said base portion, said cylindrical base portion having a continuous and closed cylindrical surface defining a hollow interior, end pieces on the opposite ends of said cylindrical base portion for covering said ends, said base portion having an opening extending through said surface for insertion of said fastening means into said hollow interior, and said paddle including a foot portion extending along said surface and completely over said opening for covering said opening.

Claim 3

The subject matter of claim 1, wherein said auger, including said paddle, is a polyethylene plastic, and said paddle is flexible in the plane of rotation of said auger for deflecting under impact with a solid object.

Claim 4

The subject matter of claim 1, wherein said base portion has two openings spaced apart on said surface in the circumferential direction of said surface, and said paddle has two foot portions with each respectively extending over said two openings.

Claim 5

The subject matter of claim 3, wherein said paddle includes a double-walLed upstanding portion intermediate said two foot portions and extending radially outwardly on said base portion, said paddle being one continuous piece extending continuously through one of said foot portions and through said double-walled portion and through the other of said foot portions.

Claim 6

The subject matter of claim 1, wherein two of said flights extend from opposite ends of said base portion to a spaced-apart relationship at the middle of the length of said base portion, said paddle being located in the space between said two flights and being of a length to substantially span said space.

Claim 7

A snow thrower auger, comprising a cylindrical base portion, spiraled flights extending on said base portion for moving snow axially along said base portion to discharge location on said base portion, a paddle extending radially outwardly on said base portion at said discharge location for engaging the snow and impelling it away from said auger, said paddle being a discrete piece distinct from and removably secured relative to the remainder of said auger and being replaceable in said auger separate from said remainder of said auger, releasable fastening means connecting said paddle with said base portion, said cylindrical base portion being two semicircular halves disposed together on a plane extending longitudinally of said cylindrical base portion to form one cylinder, said paddle being disposed on said plane and having an intermediate portion extending along said plane and having two foot portions on opposite sides of said intermediate portion and in contact with respective ones of said halves, and said fastening means being on both of said two foot portions.

Claim 8

A snow thrower auger, comprising a cylindrical base portion, spiraled flights extending on said base portion for moving snow axially along said base portion to discharge location on said base portion, a paddle extending radially outwardly on said base portion at said discharge location for engaging the snow and impelling it away from said auger, said paddle being a discrete piece distinct from and removably secured relative to the remainder of said auger and being replaceable in said auger separate from said remainder of said auger, releasable fastening means connecting said paddle with said base portion, said cylindrical base portion being two semicircular halves disposed together on a plane extending longitudinally of said cylindrical base portion to form one cylinder, said paddle being disposed on said plane and having an intermediate portion extending along said plane and having two foot portions on opposite sides of said intermediate portion and in contact with respective ones of said halves, and said fastening means being on both of said two foot portions.

Claim 9

The subject matter of claim 6, wherein said auger, including said paddle, is a polyethylene plastic, and said paddle is flexible in the plane of rotation of said auger for deflecting under impact with a solid object.

Claim 10

The subject matter of claim 6, wherein said paddle includes a double-walled upstanding portion intermediate said two foot portions and extending radially outwardly on said base portion, said paddle being one continuous piece extending continuously through one of said foot portions and through said double-walled portion and through the other of said foot portions.

Claim 11

The subject matter of claim 6, wherein two of said flights extend from opposite ends of said base portion to a spaced-apart relationship at the middle of the length of said base portion, the opposite ends of said two flights are disposed on diametrically opposite sides of said cylindrical base portion and adjacent said plane, said paddle being located in the space between said two flights and being of a length to substantially span said space.

Claim 12

The subject matter of claim 6, wherein said cylindrical base portion has a continuous and closed cylindrical surface defining a hollow interior, end pieces on the opposite ends of said cylindrical base portion for covering said ends, said base portion having an opening extending through said surface for insertion of said fastening means into said hollow interior, and said paddle foot portions extending along said surface and completely over said opening for covering said opening.

Claim 13

The subject matter of claim 6, wherein said base portion has two openings spaced apart on said surface in the circumferential direction of said surface, and said paddle foot portions each respectively extend over said two openings.
