  • Patent number: 5537710
    Abstract: For a vacuum cleaning unit, a cleaning tool employing a rotatably driven brush and having a split manifold therein which allows a vacuum airflow to be directed to the outermost longitudinal ends of the brush without interference with a drive belt rotatably driving the brush at its approximate longitudinal midpoint. The cleaning tool includes an upper housing having a centrally disposed cut-out portion and a semi-circular portion for partially housing the brush therein. A cut-out is formed in a base portion of the upper housing. A lower housing also has a cut-out shaped identically to that of the cut-out portion of the upper housing. A front sole plate is included which is secured to the lower housing and which includes a pair of openings separated by a central portion, where the openings allow portions of the brush to protrude. Each of the upper and lower housings further have runner portions which form airflow channels through which a vacuum airflow may be generated.

  • Patent number: 5280666
    Abstract: A squeegee apparatus for a vacuum cleaner system. The apparatus includes a main body portion having an integrally formed neck portion operable to releasably connect to a wand of the vacuum cleaner system. The main body portion forms a manifold and includes a lower end portion to which a squeegee member is releasably secured. The squeegee member includes a central portion having a pair of longitudinally parallel extending bumper portions, with the bumper portions each including saw tooth-shaped surfaces. The squeegee blade also depends downwardly from the central portion and outwardly of the bumper portions. The central portion also includes first and second pluralities of ports disposed on opposite sides of the squeegee blade, with one or the other of the pluralities of ports being alternately blocked off during use as the squeegee blade flexes into abutting contact with one or the other of the bumper portions while being moved back and forth over a work surface.

  • Patent number: 4824333
    Abstract: An improved blower assembly particularly useful for liquid bath type vacuum cleaners is disclosed. The improved blower assembly features enhanced noise attenuation achieved by providing a four-stage noise reduction system featureing a serpentine airflow path at the blower assembly air inlet and outlet. The four stages of the noise reduction system are comprised of: a noise reduction stage housing, a lower stage assembly, an upper stage assembly, and a motor base, respectively. Improvements in the production assembly techniques of the blower assembly components are further provided through a modified upper stage assembly which is assembled to a motor base component by a partial turn and lock procedure so that the components become firmly locked together and accurately positioned. This production technique can be accomplished quickly without a requirement of a high degree of operator skill.

  • Patent number: 4693734
    Abstract: The present invention discloses a liquid bath vacuum cleaner having a cooling air stream separated from its cleaning air stream to improve the cooling efficiency of the vacuum cleaner. The separation of the air streams accomplished by a construction comprising a pan assembly, a baffle member detachably connected to the pan assembly, a main housing detachably connected to the baffle member, a cap assembly connected to the housing, a motor assembly mounted within the cap assembly including a drive motor, a separator for drawing cleaning air into the vacuum cleaner, and a sealing mechanism to form a cleaning air cavity or pathway through the vacuum cleaner and a separate cooling air cavity for cooling air for the drive motor.
