Abstract: An elongated film strip is cleaned by two pairs of rotary brushes with soft bristles contacting opposite sides of the film strip traveling between the two pairs of brushes. Each pair of brushes is placed at an angle to the direction of film travel for brushing dirt particles away from the center of the film. The top pair of brushes and the bottom pair of brushes are arranged so that one brush in each pair brushes the particles from the central region of the film toward one edge of the film, while the other brush on the same side of the film brushes particles away from the central region of the film toward the other edge of the film. The brushes avoid contact with perforations on the edge of the film which would result in particles lodged in the perforations being brushed toward the central region of the film. A separately electrically conductive vacuum tube contacts each brush after the brush contacts the film.

Abstract: Vacuum cleaner attachments which have a V-shaped cleaning head and are particularly suited for cleaning in corners and crevices and along the edges of surfaces. Vertically biased and rotatable brushes and other disturbers can be provided to promote the dislodgement of foreign substances from the surface being cleaned; and the attachment can be constructed to operate in a first mode in which suction is concentrated in the nose of the attachment, causing it to emulate a conventional crevice tool. In a second mode of operation, the suction is distributed along the legs or wings of the attachment so that it functions in a manner akin to that of a dusting brush or floor cleaning attachment. An optional control and a detent arrangement allow more sophisticated versions of the attachment to be operated in a selected one of the foregoing modes or in a third mode in which the attachment alternates between the two first-mentioned modes of operation as it is pushed away from and pulled toward the operator.

Abstract: Vacuum cleaner attachments which have a V-shaped cleaning head and are particularly suited for cleaning in corners and crevices and along the edges of surfaces. Vertically biased and rotatable brushes and other disturbers can be provided to promote the dislodgement of foreign substances from the surface being cleaned. A preferred universal-type connection between the cleaning head and a vacuum fitting attached thereto facilitate the manipulation of the attachment and allow pressure to be brought to bear on the nose of the cleaning head, thereby promoting the dislodgement of foreign substances from the surface being cleaned.

Abstract: The disclosed spray-vacuum tool has a partitioned housing with two adjacent open faces, and defines adjacent liquid and vacuum chambers each open to both open housing faces. A pair of squeegees project beyond the open housing faces from opposite housing sides paralleling the partition, and each squeegee is angled across a sharp angle corresponding to the corner angle. A pair of end guides also project beyond the open housing faces from the other interconnecting housing sides, and the squeegee ends are butted flush against the end guides. Each end guide has a flat edge to be fitted flush against one of the respective surfaces to be cleaned, and the squeegees then are flexed then against the surfaces to be cleaned. This communicates the chambers together in the region adjacent the surfaces to be cleaned, but isolates this region from the tool exterior.

The apparatus comprises an elongate suction nozzle having a suction inlet and a longitudinal edge which comprises a scraping tool. In use, under-pressure in the suction nozzle is used to press the scraping tool against the surface and simultaneously remove liquid from the surface being scraped.

Abstract: Wall-floor edge cleaning ability in a vacuum cleaner is improved by a disk brush positioned rim with its bristles capable of floor contact and the hard, unyielding parts entirely contained in a gap in a bumper guard affixed to an exterior side wall of the housing. A stub shaft, loosely penetrating an aperture in the said housing side wall, is rigidly affixed at one extremity to the hub of the disk brush and at the other extremity axially to a free, unfettered end of a revolvable brush roll, the said brush roll horizontally supported within the nozzle area between the housing side walls. The disk brush is consequently revolvable with the brush roll. The disk brush may join the stub shaft end on a slightly oblique plane to assure better agitation of a carpet nap and direct penetration of a wall-floor edge by the rim bristles. To facilitate assembly and replacement of worn parts, the members are removably joined.

Abstract: An agitator roll for a floor care appliance or the like is disclosed having short, angled beater bars. The agitator may be of foamed plastic.

Abstract: Apparatus for cleaning a carpet using a cleaning fluid and a reciprocating head member that contacts the carpet. The cleaning fluid is applied to the carpet through a slot in the reciprocating head member. The head member further includes scrubbing means and vacuum means that are reciprocated with the cleaning fluid slot. The drive means for the reciprocating head member moves the head member back and forth along the same path at a rate of about 125 to about 585 cycles per minute. The slot for the cleaning fluid is fixedly spaced from the inlet to the vacuum means and the head member is reciprocated a distance greater than the spacing between the slot and the inlet to the vacuum means. The drive means in this embodiment is part of a body member whose mass is sufficiently greater than that of the head member so that when the drive means reciprocates the head member at a high rate, the distance moved by the head member is greater than the distance moved by the body member.
