Patent number: 7735569Abstract: A sprinkler assembly includes a sprinkler body having a base and a frame extending from the base. The base has a passage extending therethrough defining an inlet and an outlet. A deflector is mounted to the frame and spaced from the outlet, which is configured to deflect fluid flowing from the outlet in a radial pattern. A trigger assembly extends between the frame and the base and is adapted to support a plug in the outlet and release the plug when a temperature associated with a fire condition is detected. The plug is made from plastic and can include a reinforcing insert.Type: GrantFiled: June 2, 2008Date of Patent: June 15, 2010Assignee: The Viking CorporationInventor: Brian S. Green

Publication number: 20100123027Abstract: A coal nozzle assembly for a pulverized coal burner includes a diffuser. A flow conditioner also may be used with the assembly. The assembly conditions the coal/air flow before the coal/air flow is introduced to the furnace. The flow conditioner directs the coal into the diffuser where it is swirled to form a fuel rich outer ring disposed about an air rich inner portion before the fuel is delivered to the coal nozzle.Type: ApplicationFiled: November 9, 2009Publication date: May 20, 2010Inventors: Albert D.

Patent number: 7695571Abstract: A wash/rinse system for a drawer-type dishwasher includes a wash mechanism having a paddlewheel and a spray bar mounted in a washing chamber of the dishwasher. The spray bar includes at least one nozzle that is positioned so as to deliver a jet of washing fluid onto a deflector member provided on the paddlewheel. Upon impacting the deflector member, the jet of washing fluid diverges into streams of washing fluid which are sprayed onto articles positioned in the washing chamber. Preferably, the spray bar includes a plurality of nozzles which direct multiple jets of washing fluid onto a corresponding plurality of deflector members. The paddlewheel is mounted so as to create random streams of washing fluid that are sprayed into the washing chamber to combine with washing fluid emanating from a lower wash arm to clean articles in the washing chamber.Type: GrantFiled: August 9, 2006Date of Patent: April 13, 2010Assignee: Maytag CorporationInventors: Dennis J. Purtilo, Timothy P. Schwartz, Thomas J. Wuestefeld

Patent number: 7658231Abstract: A pendent type residential fire sprinkler is described. The residential fire sprinkler has a body with a K-factor of at least 6 passage coupled to a deflector assembly that distributes fluid flowing through the passage over a coverage area to perform in accordance with Underwriters Laboratory Standard 1626 (October 2003) for listing by Underwriters Laboratory Incorporated so that the body and a heat responsive trigger disposed between the passage and the deflector assembly of the sprinkler can be installed in accordance with the 2002 Edition of National Fire Protection Association Standards 13, 13D, and 13R. Various aspects of the residential fire sprinkler, including a method of protecting a residential dwelling unit are described.Type: GrantFiled: March 30, 2007Date of Patent: February 9, 2010Assignee: Tyco Fire Products LPInventors: Kenneth W. Rogers, Mark E. Fesseden, Manuel R. Silva, Jr.

Patent number: 7644877Abstract: This invention finds application in the field of liquid distributing devices, and more particularly relates to a sprinkler head device, for example for use in sprinkler systems for distributing liquids or the like. The device comprises a support body to be removably coupled to a sleeve for connection to an external liquid supply line, a convergent nozzle between the body and the sleeve, and a diverter member downstream from the nozzle for diverting flow and sprinkling fluid out. The device further includes main connection means for removably attaching the nozzle to the support body while preventing any accidental separation thereof upon mutual coupling and uncoupling of the sleeve to the body, thereby allowing fast and easy periodic replacement of the nozzle.Type: GrantFiled: May 17, 2006Date of Patent: January 12, 2010Inventor: Arno Drechsel

Patent number: RE44329Abstract: 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 is positioned proximate the outlet so as to occlude the passageway with a Bellville seal being. An ejection spring is coupled to the closure assembly. The heat responsive trigger assembly has a Response Time Index of 40 meter1/2second1/2 (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 19, 2011Date of Patent: July 2, 2013Assignee: Tyco Fire Products LPInventors: Donald B.
