Abstract

Abstract A suds-making device is attachable to the air-discharge port of an upright vacuum sweeper. A shampooing unit is easily attachable to the front of the vacuum sweeper in place of its easily removed suction-nozzle and rotating-brush unit. The shampooing unit has its own rotatable brush, similarly belt-driven by the sweeper motor, and also has a forwardly positioned transversely elongated tray to receive the applied and then scraper-blade-removed suds. The suds-making device and the shampooing unit (both of known construction) are interconnected by a detachable flexible hose. Importantly, the sudser end of the hose has attachable thereto, or molded thereon, a friction-held slip-on cap for closing the outlet port of the sudser, to stop suds flow. This cap arrangement serves two purposes: (1) preventing loss or misplacement of a separate closure cap, and (2) fastening the sudser end of the hose so that the hose need not be completely removed to prevent its flopping around during suds pick-up subsequent to suds application.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 127 words
In an upright vacuum sweeper converted into a rug-type shampooer (1) by having its rotary-brush-type suction-nozzle replaced by a shampooer unit, (2) by having its dust bag replaced by a suds-maker operatively connected to the air-discharge port of said sweeper and including a suds-discharge nipple, and (3) by having a flexible hose interconnecting said suds-maker and said shampooer unit, the suds-maker end of said flexible hose having a frictionally coupling resilient sleeve easily removably engageable over said nipple, the improvement comprising: a suds-flow-stopping cap engageable over and frictionally retainable on said nipple, said cap being attached to said sleeve, whereby loss or replacement of said cap is prevented and whereby the suds-maker end of said hose can by said cap be fastened against flopping during shampooing motions.
Claim 2
Dependent Claim 127 words
In an upright vacuum sweeper converted into a rug-type shampooer (1) by having its rotary-brush-type suction-nozzle replaced by a shampooer unit, (2) by having its dust bag replaced by a suds-maker operatively connected to the air-discharge port of said sweeper and including a suds-discharge nipple, and (3) by having a flexible hose interconnecting said suds-maker and said shampooer unit, the suds-maker end of said flexible hose having a frictionally coupling resilient sleeve easily removably engageable over said nipple, the improvement comprising: a suds-flow-stopping cap engageable over and frictionally retainable on said nipple, said cap being attached to said sleeve, whereby loss or replacement of said cap is prevented and whereby the suds-maker end of said hose can by said cap be fastened against flopping during shampooing motions.
Claim 3
Dependent Claim 13 words
Structure according to claim 1, said sleeve and said cap being integrally formed.
Claim 4
Dependent Claim 13 words
Structure according to claim 2, the integral formation being by unitary simultaneous molding.
Claim 5
Dependent Claim 18 words
Structure according to claim 1, said cap including means for easily detachably connecting said cap to said sleeve.
Claim 6
Dependent Claim 20 words
Structure according to claim 4, said means being resilient and integral with said cap and embracingly engageable with said sleeve.
Claim 7
Dependent Claim 21 words
Structure according to claim 4, said means being a resilient band fixed to said cap and grippingly slidable onto said sleeve.
Claim 8
Dependent Claim 14 words
Structure according to claim 6, said resilient band being integrally molded with said cap.
