Abstract
Abstract Structure for converting a powered brush vacuum cleaner selectively to define a powder carpet cleaning apparatus. The conversion structure includes a shroud received within the nozzle. In one form, the shroud is movably mounted within the nozzle for selective disposition in a retracted position, permitting use of the nozzle in the normal vacuum cleaning manner, and in an operative position blocking the entrance to the suction passage for permitting the unit to be used as powder carpet cleaner. The shroud defines a smooth inner surface surrounding a portion of the brush for effectively preventing clogging of the space about the brush during the carpet cleaning operation. An opening is provided in the nozzle wall for access to the movable shroud in effecting manipulation thereof between the retracted and operative positions. In another form, the shroud is fixedly mounted within the nozzle and a closure is removably installed for closing the entrance to the suction passage when it is desired to use the unit as a carpet cleaner. In the illustrated embodiment, the closure includes a tongue received in a socket portion of the shroud in the installed arrangement. Provisions are made for accommodating bridging elements extending across the nozzle opening when necessary.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
247 words
In a vacuum cleaner apparatus including a nozzle, a wand opening at one end to within said nozzle for moving the nozzle over a floor surface to be cleaned, said wand being adapted to conduct to a canister having suction creating means and first power supply means dirt picked up by the nozzle as a result of suction applied to said nozzle through said wand by the canister suction means, a powered brush rotatably carried by the nozzle, end power transmitting means carried by the wand and adapted to be removably connected to the canister first power supply means for causing selective operation of the powered brush and adapted to be connected through said first power supply means to a power source when suction is applied to the nozzle, improved means for selectively preventing transfer of dirt to said wand from said nozzle while concurrently permitting energization of said powered brush by said power transmitting means to effect a working of powder cleaner lying on said floor against the floor surface by said brush, said improved means comprising: a shroud; means for mounting said shroud movably within said nozzle to extend partially about said brush and block said wand one end; and second power supply means removably mounted to said wand adjacent the end of the wand opposite said one end in electrically connected association with said power transmitting means for operating said powered brush from a power source when said wand is disconnected from the canister.
