PA-5139-0-VC-USA "VACUUM CLEANER NOZZLE WITH DOUBLE BRUSH" ABSTRACT OF THE DISCLOSURE A vacuum cleaner nozzle having a front suction inlet and a suction passage. A first brush is rotatably mounted to the nozzle at the suction inlet, and a second brush is rotatably mounted to the nozzle adjacent the first brush at the suction inlet. A first transfer passage ex- tends from the suction inlet adjacent the first brush for passing material dislodged by the first brush to the suction passage. A second transfer passage extends from the suction inlet adjacent the second brush for transferring material from the second brush to the second transfer passage. In one form, the brushes are rotated by separate drive means, and in another form, one of the brushes is rota-ted by drive means and is coupled to the other brush for rotation thereof. The brushes, in the illustrated embodiment, rotate in oppo- site directions so that a brush is brushing relative to the movement of the vacuum cleaner and either of opposite directions of movement thereof. The transfer passages are arranged to open generally tangentially to the brushes for improved transfer of material thereinto. Portions of the walls of the structure are disposed to strip from the brushes material clinging to the periphery thereof at the entrance to the transfer passages.
