Patent number: 6554077Abstract: The sprinkler arrangements described in the specification include a sprinkler body with an axial passage and an axially movable assembly movable between a sealing position and an open position and including a Belleville washer engageable with a shoulder in the sprinkler body to seal the axial passage in the sealing position and a deflector to distribute water emerging from the passage when the movable assembly is in the open position. A locking assembly which is separable from the sprinkler body normally retains the axially movable assembly in the sealing position and is releasable by a temperature sensitive apparatus at an elevated temperature to permit the movable assembly to move to the open position. In one embodiment the axially movable member has a central post which is slidably guided by a tripod at the outer end of the axial passage.Type: GrantFiled: April 12, 2001Date of Patent: April 29, 2003Assignee: The Reliable Automatic Sprinkler Co., Inc.Inventor: George S.

Patent number: 6450266Abstract: In the typical embodiments described in the specification, a sprinkler arrangement for protecting stored documents has a sprinkler body with an orifice providing a K factor in the range from about 1.1 to about 2.7, a pair of frame arms terminating in a boss from which a glass bulb supports a cap in position to seal the orifice in the passage, and a pair of closely spaced substantially planar deflector members having a peripheral edge spacing in a range from about 0.01 inch to about 0.60 inch. The deflector member closer to the axial passage has a plurality of slots permitting some water to pass into the space between the deflector members where it generates a very fine droplet mist and some water to be distributed outwardly in the form of fine droplets to carry the mist away from the sprinkler. A recess formed in the surface of the second deflector member facing the first deflector member provides a cavity which promotes atomization and generates turbulence.Type: GrantFiled: January 24, 2001Date of Patent: September 17, 2002Assignee: The Reliable Automatic Sprinkler Co., Inc.Inventor: Oliver S.

Patent number: 6068057Abstract: In the dry pipe sprinkler valve arrangement disclosed in the specification, a dry pipe sprinkler line is normally supplied with air at a pressure in a range from about 5 psi to about 20 psi and is connected through a check valve, a dry pipe valve and a manual control valve to a water supply line. The dry pipe valve has a clapper which is normally retained in the closed position by a latch member. An actuating valve having a diaphragm which receives air pressure from the sprinkler line on one side and engages an orifice to which water from the water supply is applied on the other side permits the latch member to release the clapper when the air pressure falls as a result of opening of a sprinkler in the sprinkler line. When the system is being reset after operation the latch is either automatically movable or manually movable by an external handle to restore the clapper to its seated position without requiring opening of the dry pipe valve housing.Type: GrantFiled: March 18, 1999Date of Patent: May 30, 2000Assignee: Reliable Automatic Sprinkler Co., Inc.Inventor: John A.
