Abstract
Abstract A rug and upholstery cleaning apparatus comprising a nozzle embodying a pair of chambers separated by a baffle elevated to provide a passage therebelow, one chamber comprising a suction chamber and the other a cleaning chamber having a jet directing a stream of cleaning fluid to the area of said passage and angled to penetrate and sweep through the pile of the material being cleaned to the depth of the soil therein, the combined action of suction chamber and pressure of the stream of cleaning fluid causing the pile to tend to become erect and aligned, and the suction in a simultaneous action with the injection of cleaning fluid causes the cleaning fluid to have a sweeping action through the pile and the suction withdraws the cleaning fluid with the soil therein to the extent that whereby what is substantially dampness remains in the pile.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
In connection with a rug and upholstery material cleaning apparatus, a nozzle structure comprising a housing having a peripheral portion overlying a surface portion to be cleaned of said material, a cleaning chamber and a suction chamber within said housing, means separating said chambers positioned to provide communication therebetween at said surface portion to be cleaned, outlet jets carried in said cleaning chamber ejecting cleaning fluid at such an angle as to pass through said material at said surface portion to be cleaned, said cleaning fluid being directed to sweep through and align said surface portion, air ports into said cleaning chamber, the suction of said suction chamber simultaneous with the ejection of said cleaning fluid and incoming stream of air from said air ports raising said surface portion to be cleaned and withdrawing said cleaning fluid from and drawing said air stream through said raised surface portion in a continuous cleaning action whereby said cleaning fluid and said air stress are under constant movement in being withdrawn and discharged by said suction leaving substantially only dampness in said surface portion as a residue.
Claim 2
Dependent Claim
184 words
In connection with a rug and upholstery material cleaning apparatus, a nozzle structure comprising a housing having a peripheral portion overlying a surface portion to be cleaned of said material, a cleaning chamber and a suction chamber within said housing, means separating said chambers positioned to provide communication therebetween at said surface portion to be cleaned, outlet jets carried in said cleaning chamber ejecting cleaning fluid at such an angle as to pass through said material at said surface portion to be cleaned, said cleaning fluid being directed to sweep through and align said surface portion, air ports into said cleaning chamber, the suction of said suction chamber simultaneous with the ejection of said cleaning fluid and incoming stream of air from said air ports raising said surface portion to be cleaned and withdrawing said cleaning fluid from and drawing said air stream through said raised surface portion in a continuous cleaning action whereby said cleaning fluid and said air stress are under constant movement in being withdrawn and discharged by said suction leaving substantially only dampness in said surface portion as a residue.
Claim 3
Dependent Claim
40 words
The structure of claim 1, wherein said cleaning chamber includes a manifold, said jets being mounted onto said manifold in spaced relation, an inlet into said manifold, and a supply line to said inlet from a supply of cleaning fluid.
Claim 4
Dependent Claim
20 words
The structure of claim 1, wherein said peripheral portion is rectangular in plan defining therein a pair of elongated slots.
Claim 5
Dependent Claim
40 words
The structure of claim 1, wherein said peripheral portion is rectangular in plan defining therein a pair of slots, and said separating means comprises a wall having a raised bottom for a passage between said cleaning and said suction chambers.
Claim 6
Dependent Claim
188 words
In connection with rug cleaning apparatus, a nozzle structure comprising a housing having a peripheral portion engaging a surface portion of the pile of said rug to be cleaned, a cleaning chamber and a suction chamber within said housing, a wall separating said chambers, a raised bottom of said wall providing passage thereunder for communication between said chambers, the suction of said suction chamber drawing upon said pile at said first mentioned surface portion of said pile raising the same to upright position, jets carried in said chamber ejecting cleaning fluid, means connecting said jets to a supply of cleaning fluid, air ports allowing air flow into said cleaning chamber, a stream of air flow assisted cleaning fluid directed to said surface portion of said pile by said jets and engaging and aligning said pile in sweeping therethrough, said suction of said suction chamber withdrawing said cleaning fluid and the soil therein from said surface portion of said pile simultaneously with the movement of said air and cleaning fluid sweeping through said pile whereby substantially the only residue of said cleaning fluid is a dampness of said pile.
Claim 7
Dependent Claim
188 words
In connection with rug cleaning apparatus, a nozzle structure comprising a housing having a peripheral portion engaging a surface portion of the pile of said rug to be cleaned, a cleaning chamber and a suction chamber within said housing, a wall separating said chambers, a raised bottom of said wall providing passage thereunder for communication between said chambers, the suction of said suction chamber drawing upon said pile at said first mentioned surface portion of said pile raising the same to upright position, jets carried in said chamber ejecting cleaning fluid, means connecting said jets to a supply of cleaning fluid, air ports allowing air flow into said cleaning chamber, a stream of air flow assisted cleaning fluid directed to said surface portion of said pile by said jets and engaging and aligning said pile in sweeping therethrough, said suction of said suction chamber withdrawing said cleaning fluid and the soil therein from said surface portion of said pile simultaneously with the movement of said air and cleaning fluid sweeping through said pile whereby substantially the only residue of said cleaning fluid is a dampness of said pile.
Claim 8
Dependent Claim
35 words
The structure of claim 5, wherein said angle of said cleaning fluid being such as to direct the passage of said cleaning fluid through said pile and over the underlying base portion of said rug.
Claim 9
Dependent Claim
171 words
In connection with an upholstery material cleaning apparatus, a nozzle structure comprising a housing having a peripheral portion engaging a surface portion of material to be cleaned, a cleaning chamber and a suction chamber within said housing, means separating said chambers, providing between said chambers a passage passing over said surface portion of said material, the suction of said suction chamber drawing upon and raising said surface portion of said material, air inlet ports into said cleaning chamber, a jet carried in said cleaning chamber, means connecting said jet to a supply of cleaning fluid, a stream of cleaning fluid ejected by said jet combined with air through said ports being particularly directed at such a shallow angle as to sweep through said raised portion of said material, said suction simultaneous with the sweeping action of said air and cleaning fluid causes a continuous movement of said cleaning fluid in withdrawing the same and the soil therein from said material, whereby substantially the only residue is the dampness of said material.
Claim 10
Dependent Claim
171 words
In connection with an upholstery material cleaning apparatus, a nozzle structure comprising a housing having a peripheral portion engaging a surface portion of material to be cleaned, a cleaning chamber and a suction chamber within said housing, means separating said chambers, providing between said chambers a passage passing over said surface portion of said material, the suction of said suction chamber drawing upon and raising said surface portion of said material, air inlet ports into said cleaning chamber, a jet carried in said cleaning chamber, means connecting said jet to a supply of cleaning fluid, a stream of cleaning fluid ejected by said jet combined with air through said ports being particularly directed at such a shallow angle as to sweep through said raised portion of said material, said suction simultaneous with the sweeping action of said air and cleaning fluid causes a continuous movement of said cleaning fluid in withdrawing the same and the soil therein from said material, whereby substantially the only residue is the dampness of said material.
