Abstract: A carpeting tool for a broom-type vacuum cleaner comprising a hollow rake. The hollow rake includes a plurality of spaced hollow open-ended teeth and a plurality of spaced air passage openings interposed respectively between certain of the teeth. The hollow rake further has a pair of oppositely extending lateral hollow flange portions and a nozzle integral with and intermediary of the flange portions. The flange portions have a lowermost lateral surface from which extend the hollow teeth, and in which are formed the air passage openings. A pair of spaced apart rollers are mounted between the teeth, and extend below the open ends of the teeth to support the combined weight of the tool and vacuum cleaner when the tool is attached to the vacuum cleaner for use thereof. The rollers permit the tool to ride smoothly along the carpeting without abruptly snagging the carpeting.

Abstract: A vacuum cleaner filter bag is made of a porous sheet of material which permits penetration and flow therethrough of air. The bag is generally horseshoe-shaped and has a comparably shaped internal cavity. The bag has two tubular leg portions and a tubular connecting portion between the leg portions. An air inlet opening is provided on the connecting portion for admitting a stream of air under pressure into the cavity and an opening, which permits removal of accumulated debris but which is closed during use of the bag, is also provided on the connecting portion. The air flow between the air inlet opening on the vacuum cleaner housing and the inlet opening of an exhaust motor situated within the vacuum cleaner housing generally tends to primarily penetrate or flow through a wall portion of the bag disposed between the respective inlet air openings.
