Abstract
A fork type ceiling sprinkler includes a sprinkler body and a fork coupled to an outlet end of the sprinkler body. The fork has a pair of arms extending away from an outlet end of the body. Free end portions of the arms define a gap aligned with an outlet of the sprinkler body. A plug is releasably retained in the outlet by a pair of levers extending from the plug to sloping surfaces provided by bosses on the inner sides of the two fork arms. A temperature-sensitive element between the levers prevents the levers from sliding off sloping arms until the sprinkler is activated. A stamped deflector plate is supported on pins slidably mounted through the fork arms. A cup is adjustably mounted through bracket arms to the sprinkler on the outside of the fork arms that support the deflector.
