Abstract
In the representative embodiments described in the specification, a concealed horizontal sidewall sprinkler has a sprinkler body adapted to be connected to a source of fire extinguishing liquid. A cover support is mounted substantially concentrically to the sprinkler body and has a threaded cylindrical wall extending away from the source of fire extinguishing liquid. The threaded cylindrical wall engages a sleeve which at one end has a slotted cylindrical portion with helically arranged projections to be received in the threads of the threaded cylindrical wall of the cover support. The other end of the sleeve has a flange with a plurality of tabs extending away from the cylindrical portion. A cover is attached by solder to the tabs extending from the flange of the sleeve. The cover also has four slots and is spaced from the flange of the sleeve by the tabs forming an annular gap. Two springs affixed to the flange are interposed between the flange and the cover for urging the cover away from the sleeve when the solder fuses at elevated temperatures. The cover can be frustoconical in shape and the centerline of each slot in the cover can extend substantially in a plane with the axis of the frustoconically shaped cover.
