Patent number: 10195473Abstract: A dry sprinkler for a fire protection system. The preferred dry sprinkler has a metallic disc annulus positionable within a passageway to skew a central axis of a face of the metallic disc annulus with respect to a longitudinal axis of the dry sprinkler so that an expected minimum flow rate based on a rated discharge coefficient is provided. The dry sprinkler operates to provide an expected flow rate over a range of start pressures. The expected flow rate is based on a K-factor rating. The dry sprinkler provides an acceptable level of fluid flow rate from the expected flow rate based on the K-factor for a range of start pressures.Type: GrantFiled: March 15, 2017Date of Patent: February 5, 2019Assignee: Tyco Fire Products LPInventors: Manuel R. Silva, Jr., Thomas E. Archibald, James W. Mears, Donald B. Pounder, Yoram Ringer

Patent number: 9233266Abstract: An upright ESFR sprinkler includes a generally tubular body, at least one frame arm, a closure assembly, an unactuated heat responsive trigger assembly and a deflector assembly with a K-factor greater than 14, and preferably 16.8. The passageway extends between inlet and outlet openings. The closure assembly is positioned proximate the outlet so as to occlude the passageway with a Belleville seal. An ejection spring is coupled to the closure assembly. The heat responsive trigger assembly has a Response Time Index of 40 meter1/2-second1/2 (m1/2sec1/2) or less. The deflector assembly includes a nosepiece and a plate like redirecting member. The plate like redirecting member faces the outlet and is coupled to the at least one frame arm and spaced from the outlet opening. The plate shaped member includes a first generally planar portion, a conical second portion, and a third portion extending from the conical second portion.Type: GrantFiled: August 20, 2013Date of Patent: January 12, 2016Assignee: Tyco Fire Products LPInventors: Donald B.

Patent number: 5865256Abstract: A pendent-type fire protection sprinkler with a body defining an orifice and outlet for flow of fluid, and a deflector positioned coaxial with the outlet for impingement of fluid flow thereupon. The deflector has one or a combination of features for improved performance. For example, the deflector may have a frusto-conically shaped recess within a central area facing the sprinkler outlet, the recess defined by a surface slanted at a predetermined acute angle to the horizontal, with a plurality of holes or slots defined by the slanted surface, the recess being surrounded by an essentially flat outer area perpendicular to the sprinkler outlet axis. The deflector may have a bump, or other irregularity, on the sprinkler deflector inside surface opposed to the sprinkler outlet on each of the opposite tines in a plane perpendicular to a plane of the sprinkler frame arms. The deflector may have openings at about 45.degree.Type: GrantFiled: September 25, 1996Date of Patent: February 2, 1999Assignee: Grinnell CorporationInventor: Donald B. Pounder

Patent number: 5862994Abstract: An upright-type fire protection sprinkler with a body defining an orifice and outlet for flow of fluid, and a deflector positioned coaxial with the outlet for impingement of fluid flow thereupon, has one or a combination of the following features for improved performance. The deflector may have an inner surface with a recessed central area, and a recessed redirecting area about the central area at a predetermined acute angle and axial offset thereto. The deflector has tines with inner surfaces inclined towards the outlet, at least a first set of tines disposed in planes at about 45.degree. to a first plane of sprinkler frame arms, the surfaces of the first set of tines being inclined at an angle relatively more outward from the axis than the angle of inner surfaces of adjacent tines.Type: GrantFiled: June 25, 1996Date of Patent: January 26, 1999Assignee: Grinnell CorporationInventors: Donald B.

Patent number: 5152344Abstract: A fire protection sprinkler including a frame having an outlet opening for fire extinguishing fluid and spaced apart frame arms extending from the outlet opening to provide a support at a location spaced from the outlet opening, a sealing member covering the opening, a thermally responsive member connected between the sealing member and the support to seal off the opening during normal temperature conditions and to release the sealing member during abnornally high temperature conditions, an adapter member attached to the frame, one or more pins that are supported by the adapter member, and a deflector that is slidably mounted with respect to the adapter member via the pin or pins. Also disclosed is a clip that retains the deflector in the retracted position in a releasable fashion.Type: GrantFiled: March 25, 1991Date of Patent: October 6, 1992Assignee: Grinnell CorporationInventors: Michael A.

Patent number: 4580729Abstract: A fire protection sprinkler head which can reduce or substantially eliminate frame shadow effects that produce non-uniformity in spray pattern. The head is of the known type having a base with a throat through which fire retardant fluid flows and two or more frame arms which extend outwardly from the base and joint in an arch-form to support, in the path of fluid discharged from the throat, a central boss which deflects the fluid outwardly.Type: GrantFiled: January 22, 1985Date of Patent: April 8, 1986Assignee: Grinnell Fire Protection Systems Co., Inc.Inventor: Donald B.
