Abstract:
1. A leak stopping sprinkler head, comprising: a hollow cylindrical casing, said casing having a top surface, a central aperture penetrating said top surface, a surrounding vertical wall, a threaded attachment at a lower end of said vertical wall, said threaded attachment connecting said casing to a water supply line; a sprinkler pipe, said pipe having an upper end, a lower end and having a spray nozzle disposed at said upper end and being sized to fit slidably through said central aperture; a sealing flange, said flange being disposed about an outer circumference of said sprinkler pipe at a height to limit upward travel of said sprinkler pipe to a first predetermined distance through said central aperture as water pressure from said water supply line urges said sprinkler pipe upwards, said flange bearing against an underside of said top surface of said casing; a self-closing spring operated valve, said valve being held in an open position by said sprinkler pipe disposed therethrough, said valve controlling flow of water from said water supply line into said casing and said sprinkler pipe; and wherein said valve moves to a closed position if said sprinkler pipe moves upwardly beyond said first predetermined distance due to any of breakage and removal of either of said casing and said sprinkler pipe, thereby terminating said flow of water from said water supply line; a sphere, said sphere being pivotally mounted in a spherical seat, said seat being in fluid connection with said water supply line and said casing; said sphere having a passage therethrough, said passage being sized to fit slidably about said sprinkler pipe; an elastic member, said member urging said sphere to rotate to a closing position in said spherical seat, thereby terminating said flow of water from said water supply line; and wherein said sprinkler pipe is disposed through said passage upon mounting of said sprinkler head, thereby holding said valve in an open position, said valve moving to said closing position upon removal of said sprinkler pipe from said passage due to either of breakage and removal of either of said casing and said sprinkler pipe.
