A rotary-brush device comprising a downwardly open flat housing closed at its bottom by a cover threaded into this housing and defining a chamber in which a disk having edge-fixed vanes is received. The disk is propelled by a water jet trained on the vanes from a nipple formed on the housing and directed to the flat chamber receiving the disk. The disk is connected to a hollow shaft which rides in a recess formed in the top of this housing and in a bore of the cover, a threaded lower end of the hollow shaft carrying a rotary brush. A hollow shaft has an opening communicating with the chamber. The upper wall of the housing is provided with a passage communicating with a compartment above this wall closed by a threaded cap and receiving a liquid detergent which is to be mixed with the water.
The invention provides a water-driven brush in the form of a hand-held unit having a water inlet that can be connected to a sink faucet to provide a power source for a rotary brush that can be used for scrubbing plates or pots in the sink. A portion of the water is deflected onto the brush to facilitate the operation and the major water discharge through a main outlet can be used for rinsing the plates or pots.
A brush is disclosed having an elongated hollow handle and an integrally-secured casing. The casing has a shaft to which is rotatably secured a paddle wheel. The latter has a bottom surface to which are secured a plurality of bristles. The handle contains a water feed pipe which terminates in a nozzle inside the casing adapted to direct the water stream onto the paddle wheel. A liquid soap-dispensing means is provided in the shaft.
The water turbine provided by the present invention comprises a rotor which forms a rotor blade on one end and is bored with an exhaust liquid channel on the center of the axis to open to the center of the rotor blade, an inner casing which is bored with a nozzle on the circumference thereof and which supports said rotor in a manner to surround the rotor blade of the rotor and an outer casing having a liquid inlet port which defines a pressure chamber with the inner casing, and can be made so compact as to be held in a hand. The brush head for the pipe cleaning device which utilizes the water turbine as a driving source is so constructed that a brush is formed on an end of the rotor of the water turbine wherein the dirt or scale adhered to the inner surface of a pipe are peeled off with a rapidly revolving brush and then washed away with the pressurized liquid which has been used for revolving the water turbine.
A water operated rotatable scrubbing brush device which generates considerable scrubbing torque, without the use of gearing or diverting the majority of the water driving the device away from the brush and out of the device. The device has a two-way water flow valve that permits the operator to select between a rotatable scrubbing brush mode, wherein liquid cleaning solution will also be dispensed to the scrubbing brush, and a rinse mode, wherein clean rinse water, without cleaning solution, will be dispensed without driving the scrubbing brush, to rinse off the item being scrubbed.
A vehicle washing device includes an elongated tubular member having a first end and a second end. A coupler is fluidly coupled to the first end for coupling with a water supply hose. A housing includes a top wall and a peripheral wall. The second end of the tubular member is attached to the top wall of the housing and is fluidly coupled to a plurality of nozzles mounted in the housing. A plurality of spindles is rotatably mounted in the housing. Each of the spindles has a central portion and a pair of lateral portions. A plurality of paddles is attached to each one of the central portions. The central portions are positioned such that the spindles are rotated when jets of water from the nozzles strike the paddles. A plurality of bristles is attached to each one of the lateral portions of the spindles.
