Abstract
Abstract A tool for cleaning and straightening the elongated pile of a shag rug which comprises an assembly of elongated resilient members mounted adjacent the air intake opening of a vacuum cleaner nozzle which have limited pivotal movement about an axis generally parallel to the longitudinal axis of the air intake opening of the vacuum cleaner nozzle with the lower end of each member being maintained in resilient engagement with the elongated pile of the shag rug to effect straightening the pile when the nozzle is moved in contact with the shag rug.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
248 words
A tool for a rug having elongated nap comprising; an assembly of spaced elongated resilient finger members adapted to be operatively associated with a cleaner nozzle, said resilient finger members normally extending outwardly and downwardly relative to the lower surface of said nozzle along substantially the length of said nozzle, each of said resilient finger members being pivotally movable in a plane generally perpendicular to the plane of the lower surface of said nozzle about an axis lying in a plane substantially parallel to said plane with the upwardly pivotal movement of each said finger member being limited, the outer end portions of said finger members being flexed outwardly away from said nozzle a distance greater than normal with the end of each said finger member being maintained in resilient engagement with said rug to effect straightening of said elongated nap when said nozzle is moved in one longitudinal direction along said rug, and said finger members being pivotally movable downwardly and inwardly toward said nozzle until said outer end portions thereof extend in a plane generally parallel to the plane of the lower surface of said nozzle with the said ends of said finger members being maintained out of resilient engagement with the surface of said rug when said nozzle is moved in the opposite longitudinal direction along said rug; whereby the elongated nap of said rug is arranged in substantially one longitudinal direction when said nozzle is moved reciprocably longitudinally over the surface of said rug.
Claim 2
Dependent Claim
248 words
A tool for a rug having elongated nap comprising; an assembly of spaced elongated resilient finger members adapted to be operatively associated with a cleaner nozzle, said resilient finger members normally extending outwardly and downwardly relative to the lower surface of said nozzle along substantially the length of said nozzle, each of said resilient finger members being pivotally movable in a plane generally perpendicular to the plane of the lower surface of said nozzle about an axis lying in a plane substantially parallel to said plane with the upwardly pivotal movement of each said finger member being limited, the outer end portions of said finger members being flexed outwardly away from said nozzle a distance greater than normal with the end of each said finger member being maintained in resilient engagement with said rug to effect straightening of said elongated nap when said nozzle is moved in one longitudinal direction along said rug, and said finger members being pivotally movable downwardly and inwardly toward said nozzle until said outer end portions thereof extend in a plane generally parallel to the plane of the lower surface of said nozzle with the said ends of said finger members being maintained out of resilient engagement with the surface of said rug when said nozzle is moved in the opposite longitudinal direction along said rug; whereby the elongated nap of said rug is arranged in substantially one longitudinal direction when said nozzle is moved reciprocably longitudinally over the surface of said rug.
Claim 3
Dependent Claim
17 words
A tool as in claim 1, wherein each said finger member is mounted for independent pivotal movement.
Claim 4
Dependent Claim
43 words
A tool as in claim 1, wherein each of said finger member has an abutment surface for engaging a surface of said nozzle which limits upwardly pivotal movement of said finger members and maintains said finger members in resilient engagement with said rug.
Claim 5
Dependent Claim
25 words
A tool as in claim 1, wherein a plurality of said finger members are pivotally mounted on an axle member detachably supported on said nozzle.
Claim 6
Dependent Claim
22 words
A tool as in claim 4, wherein said axle member is supported by spaced spring means which resiliently detachably engage said nozzle.
Claim 7
Dependent Claim
94 words
A tool as in claim 5, wherein said spring means comprises a support section adjacent the opposite ends of said axle member which extends below the plane of said lower surface of said nozzle when said spring means is operatively mounted on said nozzle with said Support section slidably supporting said nozzle on said rug with a transverse edge of said nozzle which is proximate to said finger members being elevated above the surface of said rug a greater distance than the transverse edge of said nozzle which is spaced from said finger members.
