Nozzle, Revolving Cellar
Nozzle, Revolving Cellar : Consists of a female round-thread or male instantaneous coupling carrying a semi-spherical metal casting which is able to revolve on it freely in a plane at right angles to the coupling. Fitted to this casting are four 5 mm (3/16 in. nozzles at right angles to the hose. Two diametrically opposite nozzles throw jets in the plane of revolution whilst, of the other two, one is turned slightly upward and the other slightly downwards. As water passes through the branch under pressure the semi-circular casting revolves, throwing out a curtain of water in all directions
