Vacuum nozzle for carpeted stair treads and risers

Claim 2

A nozzle for cleaning a carpeted stair tread and riser comprising a hollow cylindrical body having a hollow extension in one end for connection to a source of suction, said body having an elongated port in its wall extending from the other end thereof and adjusted to lie against a surface having matter to be removed by said suction, and valve means cooperating with said body for selectively restricting the axial length of the passageway through said port to the width of a stair tread or a stair riser, said valve means comprising a hollow cylindrical sleeve member which conforms in size and shape to the inner wall of said body and being selectively rotatably mounted therein with a friction fit.

Claim 3

A nozzle according to claim 1 wherein said hollow extension is directed at an angle to said cylindrical body in the plane thereof and forms a handle therefor simulating a pistol grip.

Claim 4

A nozzle for cleaning a carpeted stair tread and riser comprising a hollow cylindrical body having a hollow extension in one end for connection to a source of suction, said body having an elongated port in its wall extending from the other end thereof and adjusted to lie against a surface having matter to be removed by said suction, and valve means cooperating with said body member for selectively restricting the length of the passageway through said port to the width of a stair tread or a stair riser, said valve means comprising a hollow cylindrical sleeve member which conforms in size and shape to the inner wall of said body and is rotatably mounted therewith with a friction fit wherein the wall of said sleeve member is provided with a plurality of slots extending axially from the outer end thereof and which are angularly spaced, said slots being of different lengths, one of said slots corresponding to the length of a stair riser and another of said slots corresponding to the width of a stair tread.

Claim 5

A nozzle for cleaning a carpeted stair tread and riser comprising a hollow cylindrical body having a hollow extension in one end for connection to a source of suction, said body having an elongated port in its wall extending from the other end thereof and adjusted to lie against a surface having matter to be removed by said suction, and valve means cooperating with said body member for selectively restricting the length of the passageway through said port to the width of a stair tread or a stair riser, said valve means comprising a hollow cylindrical sleeve member which conforms in size and shape to the inner wall of said body and is rotatably mounted therewith with a friction fit wherein the wall of said sleeve member is provided with a plurality of slots extending axially from the outer end thereof and which are angularly spaced, said slots being of different lengths, one of said slots corresponding to the length of a stair riser and another of said slots corresponding to the width of a stair tread.

Claim 6

A nozzle according to claim 3 including a closure cap secured to the outer end of the cylindrical sleeve member, said cap providing a handle for moving said valve to locate a selected slot in registration with said port in the cylindrical body member.

Claim 7

A nozzle according to claim 4 wherein said cap is provided with a radially extending slot at its peripheral edge for applying suction to the corner formed by a stair tread and riser.

Claim 8

A nozzle according to claim 4 including a liquid jet spray nozzle secured to the exterior wall of said body member having means for connecting it to a source of cleaning liquid for applying said liquid to the carpet to be cleaned.

Claim 9

A nozzle according to claim 6 including a manually operated valve secured to the outer wall of the cylindrical body for controlling flow of cleaning fluid to said spray nozzle.
