Fire break device

A fire break device connectable to a source of pressurized water and suitable for use adjacent the exterior of structures, said fire break device comprising:

• a) a rigid conduit member having a fluid passageway therein in connection between a first and second end opening, and at least one discharge orifice in fluid communication with said fluid passageway, said first end opening including means for connection with a source of pressurized fluid;
• b) a first blocking valve installed within said fluid passageway in a manner to block the passage of fluid through said second end opening when said first blocking valve is in a closed position and to allow the passage of fluid through said second end opening when said blocking valve is in an open position;
• c) a base member including a planar member and a connecting member, said planar member having a first and second surface, said second surface being substantially planar and adapted for contact with a substantially flat surface, said connecting member being substantially rectangular shaped and having a first and second end, said first end being connected to said first surface, said second end being connected to said rigid conduit member at a location and in a manner such that said discharge orifice is oriented away;
• and
• d) a diffuser connected to said rigid conduit member and positioned in relationship with said discharge orifice in a manner such that said diffuser contacts and diffuses a portion of a fluid stream discharged from said discharge orifice, said diffuser being hollow and frustrum shaped and including a first substantially rectangular shaped opening and a second opening having a smaller area than said first opening and a substantially circular perimeter, said second opening being positioned over and surrounding said discharge orifice.
