Abstract

Abstract A suction cleaner nozzle having a power driven rotary brush mounted on the nozzle aligned with the nozzle inlet opening and a shag rug attachment mounted on adjustable nozzle supporting wheels. A motor is mounted on the nozzle and is connected to the brush by a belt for power driving the brush. The nozzle has a pair of front and rear wheels for roller supporting the nozzle when being used without the shag rug attachment. The front wheels are journaled on the ends of a pivotally mounted lever which is engaged by an eccentric cam for varying the nozzle inlet opening and brush height above a surface being cleaned. The shag rug attachment has a pair of spaced skid-like runners extending laterally of the nozzle inlet opening and a rake pivotally mounted at the front end of the runners. A pair of spring clips is mounted on the runners and detachably connect the shag rug attachment to the nozzle front wheels, whereby adjustment of the wheels by the lever varies the distance that the shag rug attachment is spaced below the nozzle inlet opening.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 141 words
In a suction cleaner nozzle of the wand-type in which a power driven brush is rotatably mounted in a nozzle housing adjacent a nozzle mouth formed in the housing bottom wall and in which the housing is supported on at least a pair of axially aligned adjustably mounted wheels movable with respect to the housing bottom wall adjacent the nozzle mouth; the combination of a shag rug cleaning attachment having a generally rectangular frame including spaced runners, a rake member journaled for pivotal movement on the runners at one end thereof, spring clip means on each runner intermediate its ends detachably engaged with the wheels, and means detachably loosely movably mounting the other runner ends on the housing bottom wall; whereby adjustment of the aligned wheels varies the location of the runners and rake member with respect to the nozzle mouth.
Claim 2
Dependent Claim 141 words
In a suction cleaner nozzle of the wand-type in which a power driven brush is rotatably mounted in a nozzle housing adjacent a nozzle mouth formed in the housing bottom wall and in which the housing is supported on at least a pair of axially aligned adjustably mounted wheels movable with respect to the housing bottom wall adjacent the nozzle mouth; the combination of a shag rug cleaning attachment having a generally rectangular frame including spaced runners, a rake member journaled for pivotal movement on the runners at one end thereof, spring clip means on each runner intermediate its ends detachably engaged with the wheels, and means detachably loosely movably mounting the other runner ends on the housing bottom wall; whereby adjustment of the aligned wheels varies the location of the runners and rake member with respect to the nozzle mouth.
Claim 3
Dependent Claim 49 words
In the construction defined in claim 1, the nozzle mouth being located in the housing bottom wall adjacent the front end of the housing, the rake member being located in front of the front end of the housing, and the pair of wheels being located behind the nozzle mouth.
Claim 4
Dependent Claim 37 words
In the construction defined in claim 1, the brush extending parallel with the rake member and the aligned wheels, and the axis of rotation of the brush being located intermediate the rake member and pair of wheels.
Claim 5
Dependent Claim 53 words
In the construction defined in claim 1, a pair of spaced aligned slots formed in the housing bottom wall adjacent to and rearwardly of the nozzle mouth, said pair of axially aligned wheels being movable through said slots, and the spring clip means extending through said slots when detachably engaged with the wheels.
Claim 6
Dependent Claim 51 words
In the construction defined in claim 1, each runner having an upturned front end, a frame cross bar member connecting the upturned runner front ends and located forwardly of the nozzle housing, bracket means mounted on the upturned front runner ends, and the rake member being journaled in said bracket means.
Claim 7
Dependent Claim 124 words
In the construction defined in claim 1, the means detachably mounting the other runner ends on the housing bottom wall including, a curved member formed with a slot at the terminal portion of said other end of each runner, the housing bottom wall having an opening formed therein behind each wheel of the pair of wheels, post means within the housing adjacent each opening, and the slotted ends of the curved terminal runner portions being inserted through said openings and loosely engaged with said post means when the shag rug attachment is detachably mounted on the nozzle; whereby the loose engAgement permits varying of the location of the runners and rake member with respect to the nozzle mouth upon adjustment of the aligned wheels.
Claim 8
Dependent Claim 252 words
In a suction cleaner nozzle of the type in which a power driven brush is rotatably mounted in a nozzle housing adjacent a nozzle mouth formed in the housing bottom wall and in which the housing is supported on at least a pair of axially aligned adjustably mounted wheels movable with respect to the housing bottom wall adjacent the nozzle mouth; the combination of a shag rug cleaning attachment having a generally rectangular frame including spaced runners, a rake member journaled for pivotal movement on the runners at one end thereof, spring clip means on each runner intermediate its ends detachably engaged with the wheels, a pair of spaced aligned slots formed in the housing bottom wall adjacent to and rearwardly of the nozzle mouth, the pair of axially aligned wheels being movable through said slots for adjustment, the spring clip means extending through said slots and detachably engaged with the wheels, a curved member formed with a slot at the terminal portion of the other end of each runner, the housing bottom wall having an opening formed therein behind each wheel receiving slot, post means within the housing adjacent each opening, and the slotted ends of the curved terminal runner portions being inserted through said openings and loosely engaged with said post means when the shag rug attachment is detachably mounted on the nozzle; whereby the loose engagement permits varying of the location of the runners and rake member with respect to the nozzle mouth upon adjustment of the aligned wheels.
Claim 9
Dependent Claim 252 words
In a suction cleaner nozzle of the type in which a power driven brush is rotatably mounted in a nozzle housing adjacent a nozzle mouth formed in the housing bottom wall and in which the housing is supported on at least a pair of axially aligned adjustably mounted wheels movable with respect to the housing bottom wall adjacent the nozzle mouth; the combination of a shag rug cleaning attachment having a generally rectangular frame including spaced runners, a rake member journaled for pivotal movement on the runners at one end thereof, spring clip means on each runner intermediate its ends detachably engaged with the wheels, a pair of spaced aligned slots formed in the housing bottom wall adjacent to and rearwardly of the nozzle mouth, the pair of axially aligned wheels being movable through said slots for adjustment, the spring clip means extending through said slots and detachably engaged with the wheels, a curved member formed with a slot at the terminal portion of the other end of each runner, the housing bottom wall having an opening formed therein behind each wheel receiving slot, post means within the housing adjacent each opening, and the slotted ends of the curved terminal runner portions being inserted through said openings and loosely engaged with said post means when the shag rug attachment is detachably mounted on the nozzle; whereby the loose engagement permits varying of the location of the runners and rake member with respect to the nozzle mouth upon adjustment of the aligned wheels.
