  • Patent number: 6746059
    Abstract: A latch assembly for a removable dirt separation system is disclosed. The latch assembly includes an actuator having an latch opening defined therethrough pivotally mounted to a lid of the dirt separation system. The latch assembly further includes a latch positioned beneath the actuator and having a latching surface which is operable to engage a catch on a vacuum cleaner housing. A latching surface of the latch extends through the latch opening. Moving the actuator in a first direction causes the actuator to disengage the latching surface of the latch from the catch and place the latch assembly in a disengaged position. Moving the latch in the first direction causes the latching surface of the latch to pass through a latch opening defined in the actuator to place the latch assembly in a return position. A method of operating a latch assembly is also disclosed.

  • Patent number: 5652996
    Abstract: A hand held cleaner is provided with a swiveling nozzle that moves from a position perpendicular to the cleaner body to a position of axial alignment with it. A series of stops are mounted on the swiveling nozzle and cleaner body to limit nozzle swing to these two positions. A reciprocable latch is mounted with the nozzle to engage, selectively, in one of a pair of latching apertures in the cleaner body to lockingly maintain the swiveling nozzle of its stopped positions. The agitator and agitator belt are offset from what would be considered their normal centered relationship to accommodate the swiveling action of the hand held cleaner nozzle.
