Abstract: A liquid dispenser. The liquid dispenser includes a pump chamber connected to a storage chamber through a first passage. A valve body extends through the first passage and controls the liquid flow around the valve body and between the pump chamber and the storage chamber. The valve body provides a second internal connecting passage between the pump chamber and the storage chamber and an additional valve located within the valve body controls the flow of liquid between the pump chamber and storage chamber through the second internal connecting passage.

Abstract: A cleaning system utilizing a hollow bodied, disposable dispensing capsule or package comprising a storage chamber and integral dispensing chamber made of a plastic material. The package is connected to the system handle via a conical protrusion on the package closure. An orifice separating the two chambers is provided with a movable, inlet clapper valve, the dispensing chamber outlet orifice being normally closed by a spring urged valve. Deformation of the elastic walls of the bellows shaped dispensing chamber dispenses a discrete amount of liquid to the system handle without relying on gravity. Compression of the dispensing chamber reduces the volume thereof, closes the inlet clapper valve, and opens the outlet valve to dispense the product. The conically shaped storage chamber provides for ready pumping and evacuation of cleaning fluid therefrom, the flexible walls collapsing inward as a result of the vacuum created by the decompression of the dispensing chamber.

Abstract: A safety lock mechanism for a cleaning wand. A three position slide switch alternately engages a pivotal trigger and/or a pivotal door on the end of the wand handle opposite the cleaning head. In the first position, the trigger is locked and the door openable. In the second position, the trigger and door are both locked. In the third position, the handle door is locked but the trigger is operable. Controlled engagement of the trigger and/or door with the slide switch prohibits unwanted loss or discharge of cleaning fluid.

Abstract: A cleaning system (60) includes an elongate handle (61) having a surface cleaning means (65) disposed at one end of the handle and a cleaning fluid cartridge means (64) disposed at the other end of the handle. The cleaning system further includes a means for pumping (66) the cleaning fluid from the fluid cartridge means to the surface cleaning means, and the pump means (66) is associated with the cleaning fluid cartridge means.

Abstract: A cleaning fluid cartridge, adapted for use with a cleaning system having a handle and a cleaning brush attached thereto, wherein a flexible bag contains the cleaning fluid, and a check valve is sealingly disposed within an opening in the flexible bag.

Abstract: An apparatus for dispensing liquid with a specialized refill including a flexible reservoir and mesh screen is disclosed. The apparatus includes a housing; a flexible reservoir for storing the liquid; disposed within the housing; a flexible tubular member connected to the reservoir for selectively dispensing the liquid from the reservoir; and, a flexible mesh screen disposed within said reservoir. The flexible mesh screen produces a plurality of flow channels between the reservoir material and the output orifice of the reservoir to enable said liquid to continuously empty into said tubular member. In a preferred embodiment, the screen is a square screen with a side dimension at least equal to the diameter of the output orifice at the bottom of the reservoir and is fabricated from a plastic coated fiberglass material.

Abstract: A toggle-type power regulator is adapted to shunt or open a power control circuit at opposite limit positions and has infinitely variable power control at all intermediate positions between the limit positions. A potentiometer incorporated in the control circuit comprises a pair of arcuate tracks of resistive and conductive material positioned on opposite faces of the control circuit substrate. Variable voltage output is achieved as the tracks are engaged or wiped by the opposed resilient contactors of a caliper which is connected for movement by the toggle. The regulator includes a one-piece dual blade switch assembly through which the toggle is yieldably held in the intermediate positions at which reduced power is supplied to the load.
