Concealed sprinkler assembly
 A concealed, flush mounted sprinkler is disclosed which comprises a slidable deflector which, in the event of fire, is extended to an operating position by means of a compressed spring. The nozzle, a thermally responsive element, and the deflector of the sprinkler reside within a receptacle having an outer cover against which the deflector is continuously pressured by means of the spring. The cover is attached to the receptacle by means of a fusible eutectic alloy, and as the alloy begins to soften and become elastic during a fire, the compressed spring aids detachment of the cover from the receptacle while simultaneously sliding the deflector to an operating position beyond the ceiling or sidewall in which the sprinkler is mounted.
