Abstract: An automatic spray nozzle for use in a fire extinguishing system includes an apertured body member, a closure cap, a frame supporting a novel deflector, and a cylindrical ferrule positioned below the novel deflector and spaced with respect thereto. A strut holds the closure cap and a lever bearing against the strut is releasably retained by a transversely disposed fusible element engaging spaced apertured arms on the strut. The combination of the cylindrical ferrule and the novel deflector including a conical portion provides a water distribution pattern which is much more uniform than the spray patterns produced by the prior art devices.
