Abstract: A sprinkler head comprises a tubular body having a first threaded end to be connected to a water line and having a second end that defines an outlet enclosed by a cap. A thermally responsive element, such as a glass bulb or heat fusible element, is engaged with the cap to maintain the cap in a closed position. The body is provided with a pair of generally parallel circumferential grooves. The bottom of one of the grooves adjacent the threaded end has a polygonal cross section to receive a wrench to enable the sprinkler head to be threadedly attached to a water line, while the other of the grooves receives the base portion of a wire-form protective guard that encloses the thermally responsive element.

Abstract: A sprinkler head including a frame or body having an opening to be connected to a water line. The body also includes a pair of arms which are joined together at a junction. A cap encloses the opening and a releasable mechanism, such as a frangible glass bulb, is connected between the junction and cap. When the sprinkler head is exposed to an elevated temperature, the glass bulb will fracture releasing the cap to permit water to be discharged from the opening. The sprinkler head includes an ejection mechanism which prevents the cap from hanging up on the arms. The ejection mechanism has a base connected to a projection on the upstream side of the cap and a skirt extends longitudinally from the base and terminates in a thin edge facing upstream.

Abstract: An improved concealed sprinkler head assembly that incorporates a standard pendant-type sprinkler head includes a frame having an outlet that is connected to a water line and a valve cap that encloses the outlet and is held in the closed position by a releasable lever mechanism which includes a fusible metal. The assembly also includes a pre-assembled cover plate unit that consists of a disc having a central opening that is slid upwardly over the frame of the sprinkler head. The cover plate unit also includes a tubular sleeve having a pair of opposed notches which receive projections on the periphery of the disc. A decorative cover plate is secured through a fusible metal, such as solder, to the lower edge of the sleeve, and a coil spring, in a compressed condition, interconnects the upper end of the sleeve with the disc.

Abstract: A partially concealed fast response sprinkler head having a body defining an inlet to be connected to a water line and having an outlet normally enclosed by a valve cap. The upper ends of a pair of lever members are supported on an internal shoulder in the body. Each lever member is generally semicircular in cross section and the lower ends of the lever members taper inwardly and define a central passage. The valve cap is provided with a threaded bore which receives a screw and the head of the screw engages a retaining bar, the ends of which bear against the upper ends of the respective lever members at a location spaced inwardly from the engagement of the lever members with the body, so that the force of the retaining bar against the lever members will tend to pivot the lower ends of the lever members outwardly away from each other.

Abstract: A fast response sprinkler head. The sprinkler head includes a frame having a base portion connected to a source of water under pressure and a pair of arms extended outwardly from the base and are connected at a junction. A cap normally encloses the outlet in the base and a lever assembly, which extends between the junction and the cap, holds the cap in the closed position. The lever assembly includes a pair of lever members, with one of the lever members being biased in a direction away from the other lever member. A fusible link assembly interconnects the lever members and includes a pair of thin metal sheets that are joined together by a layer of fusible metal or solder. Each sheet is formed with a recess in one side edge and the recesses face each other to define an opening which receives the lever member. The corners of each sheet are bent generally normal to the sheet to provide fins or tabs.

Abstract: An improved recessed sprinkler head including a frame having a base portion with an outlet to be connected to a source of water under pressure. The frame also includes a pair of curved arms which extend outwardly from the base portion and are connected together at a junction. The outlet is normally enclosed by a cap which is retained in position by a releasable mechanism that includes an element arranged to release when the sprinkler head is exposed to a predetermined elevated temperature. A disc-like support member having a central aperture of sufficient size to receive the arms of the frame is slipped upwardly over the frame after the sprinkler head is connected to the water line, and the support member includes a pair of opposed flexible resilient tabs that are adapted to engage an abutment on the base portion of the frame. An annular sleeve is positioned outwardly of the frame, and the lower end of the sleeve defines a decorative ring.

Abstract: An improved sprinkler head for an automatic fire extinguishing system. The sprinkler head comprises a frame having a discharge orifice and a deflector spaced from the orifice. A cap normally encloses the discharge orifice and is held in place by a lever assembly. The lever assembly includes a lever having a pair of spaced side flanges and a tube extends between the flanges. Located within the central portion of the tube is a fusible element and balls are positioned in the ends of the tube on either side of the fusible element and engaged with sockets in the respective flanges. In the event the element is subjected to an elevated temperature, it will melt causing the balls to move inwardly of the tube and thereby releasing the lever assembly to open the discharge orifice.

Abstract: A liquid flow indicator for use in an automatic sprinkler system. The indicator is adapted to be attached to a water line and includes a non-metallic vane retainer or support which is mounted within an opening in the water line. A flexible one-piece plastic vane is pivoted to the retainer and has a generally circular body portion which is disposed transversely within the pipe. If the water line is opened downstream of the indicator, the flow of water within the line will pivot the vane, causing a magnet in the upper end of the vane to move into proximity with a sensor to complete an electrical circuit and generate a signal indicating that the water line has been opened. The retainer is formed with a pair of aligned recesses which are sealed apart by a central wall and the upper head of the vane which contains the magnet, is located in one recess, while the sensor is in the other recess.
