Water temperature control device

A faucet wherein the maximum amount to which the faucet can be opened is settable by a user, comprising:

• a face plate having a sleeve portion, said sleeve portion having first and second open ends, a longitudinal axis, and a hollow interior, said face plate being capable of fitting over a valve having a valve stem so as to allow the valve stem to pass through said first open end and be housed substantially within said hollow interior of said sleeve portion;
• a knob having a top portion and a bottom portion, said bottom portion having a cavity receiving a portion of said sleeve portion proximate said second open end, said knob further having a threaded sleeve provided within said cavity, said threaded sleeve passing through said second open end and being positioned within said sleeve portion;
• a fastener passing substantially centrally through said knob and engageable with the valve stem;
• first and second setscrews each having a longitudinal axis and each passing through said knob so as to penetrate into said cavity and so as to have a portion thereof be positioned within said cavity, said longitudinal axes of said first and second setscrews passing between said threaded sleeve and said sleeve portion;
• and
• a stop collar matingly engaging said threaded sleeve, whereby turning said knob causes said stop collar to move along said threaded sleeve and said knob is substantially prevented from turning once said stop collar contacts one of said first and second setscrews.
