Claim 8

An air cleaner having in combination a housing comprised of a plate member partially convolute in form, said plate member forming an outer wall of said housing and having a portion thereof forming an inner wall spaced from an adjacent portion of said outer wall forming therebetween an inlet into said housing, a screen overlying said inlet, said housing having an outlet spaced from said inlet, an inner wall member disposed inwardly of an outer wall portion of said housing spaced therefrom to form a duct of narrow radial width therewith, said duct having an inlet spaced from said inlet of said housing and having an outlet communicating with said outlet of said housing, a top wall of said duct declining from said inlet toward said outlet of said duct, an upright member within said housing disposed in an axially off center position in said housing providing a passage of increasing volume substantially thereabout from said inlet of said housing in the direction of said outlet of said housing, said upright member having a vent therein, and a passage in said upright member communicating with said vent.

Claim 9

An air cleaner having in combination a housing comprised of a plate member partially convolute in form, said plate member forming an outer wall of said housing and having a portion thereof forming an inner wall spaced from an adjacent portion of said outer wall forming therebetween an inlet into said housing, a screen overlying said inlet, said housing having an outlet spaced from said inlet, an inner wall member disposed inwardly of an outer wall portion of said housing spaced therefrom to form a duct of narrow radial width therewith, said duct having an inlet spaced from said inlet of said housing and having an outlet communicating with said outlet of said housing, a top wall of said duct declining from said inlet toward said outlet of said duct, an upright member within said housing disposed in an axially off center position in said housing providing a passage of increasing volume substantially thereabout from said inlet of said housing in the direction of said outlet of said housing, said upright member having a vent therein, and a passage in said upright member communicating with said vent.

Claim 10

The structure set forth in claim 6, wherein said housing has a bottom wall defining a helical path from said inlet of said housing about said upright member to said outlet of said housing.

Claim 11

The structure set forth in claim 6, wherein said upright member has a passage thereabout extending from said inlet into said housing to said outlet from said housing, a wall defines the outlet end of said passage adjacent said outlet of said housing, and said last mentioned wall has an outlet therein adjacent the bottom thereof communicating with said outlet from said housing.

Claim 12

The structure set forth in claim 8, including a discharge means carried by said housing communicating with said outlet from said housing.

Claim 13

The structure set forth in claim 6, wherein said inlet end of said duct is spaced from said inlet of said housing and said outlet end of said duct engages said outlet of said housing.

Claim 14

An air cleaner having in combination a cylindrical housing formed with an outer wall, an inner wall spaced from said outer wall forming a duct of narrow radial width within said housing, said duct decreasing in height from an inlet end toward an outlet end thereof and having an overlying top wall, an inlet into said housing tangential thereto and having communication with the adjacent inlet end of said duct, an upright member within said housing disposed in an axially off center position with respect thereto in the direction of said inlet and with respect to said duct partially thereabout, said upright member having a vent therein, and a passage in said upright member communicating with said vent.

Claim 15

An air cleaner having in combination a cylindrical housing formed with an outer wall, an inner wall spaced from said outer wall forming a duct of narrow radial width within said housing, said duct decreasing in height from an inlet end toward an outlet end thereof and having an overlying top wall, an inlet into said housing tangential thereto and having communication with the adjacent inlet end of said duct, an upright member within said housing disposed in an axially off center position with respect thereto in the direction of said inlet and with respect to said duct partially thereabout, said upright member having a vent therein, and a passage in said upright member communicating with said vent.
