  • Patent number: 5887313
    Abstract: An upright wet extractor includes a base assembly, a manipulative handle pivotally attached to the base assembly, and a motor driven agitator brush. A cleaning solution dispensing tank is removably attached to the handle assembly by a pivotable latch member. In a floor cleaning mode, cleaning solution is selectively supplied by gravity from an outlet of the dispensing tank to a floor cleaning spray nozzle through a supply tube which is controlled by a pinch valve. In an attachment hose cleaning mode, cleaning solution is selectively supplied by a motor driven pump from the dispensing tank to an attachment hose spray nozzle which is controlled by a trigger valve. A valve is provided in the outlet of said dispensing tank. The valve has a stem moveable between a closed position sealing the outlet and an open position providing fluid communication between the dispensing tank and the nozzle.

  • Patent number: 4017937
    Abstract: A hose coupling for detachably connecting one end of a cleaning tool hose to the suction inlet of a suction cleaner. The coupling includes a female coupling portion comprising a pair of circumferentially spaced, diametrically arranged flange portions on the margin of the suction inlet, and a male coupling portion comprising diametrically-spaced lug means on the end of the hose. The lug means are axially shiftable through recesses in the flange portions when the end of the hose is positioned for initial insertion into the inlet. After initial insertion, the end of the hose is rotated through a predetermined number of degrees to a locked, operative position in the inlet. A spring biased detent holds the end of the hose in its locked operative position, and a manually actuated push-button permits a user to disengage the detent from a receiving notch in one of the flange portions so that the end of the hose can be rotated to its initial insertion position and then withdrawn axially from the suction inlet.
