Abstract
A hand-held tool with a rotary pumice or suitable synthetic grinding wheel is connected by means of a flexible drive cable to a remote water turbine contained in a floating housing and is used to remove calcium deposits from decorative tile around a periphery of a swimming pool. The outlet of the water turbine is connected to one end of a suction hose, the other end of which is connected to a suction inlet of an electric pump/filter unit, causing water to be drawn from the swimming pool through the turbine. In an alternate embodiment of the invention, the remote turbine is placed in a lavatory sink. Water from a faucet is forced through the turbine, causing rotation of the drive cable, so that the hand tool can be used to clean calcium deposits from bathroom facilities.
Claims9
Apparatus for removing mineral deposits from interior surfaces of water-containing vessels, said apparatus comprising in combination:
- (a) a hand-held tool having a rotary drive shaft;
- (b) a grinding wheel attached to said drive shaft;
- (c) a relatively long flexible drive cable assembly having a non-rotary housing and a coaxial rotary cable core element, said drive cable assembly having a first end and a second end, said first end being connected to said hand tool, said cable core element being operatively coupled to said drive shaft to translate rotation of said cable core element to said drive shaft;
- (d) a remote water-powered turbine connected to said second end of said drive cable assembly, said turbine including a rotor operatively coupled to said cable core element to translate rotation of said rotor to said cable core element, said turbine having first and second ports through which water is forced to cause said rotor to rotate, said turbine being supported in a housing that is buoyant to allow a user of said hand tool to easily pull said turbine along as said user deploys said hand tool to grind mineral deposits off of the interior surfaces of said swimming pool;
- and
- (e) means for forcing water to flow through said first and second ports to effect rotation of said rotor.
