Messrs. Burn Brothers also manufacture a fixed spray, [Fig. 114], called the Burn and Brown’s Patent “Whirl” Spray. The special feature of this is that it consists of an inverted conical spreader, provided with vanes revolving on a spindle. The sewage, as it leaves the nozzle, impinges upon the face of the cone, causing it to revolve rapidly and spread the sewage in the form of fine drops. Owing to the special construction of the serrated edges of the cone, the sewage is well distributed over the whole area covered by the spray.
