Nixon's Climax nozzle is excellent for spraying clear liquids, but its 

 use demands considerable power in the pumps. 



Fig. 1. — Nixon's Climax Nozzle.— This is made in three sizes, differing in size of jet and "no." of 

 the gauze used to cover the top. 



The Vermorel modification of the eddy chamber or cyclone nozzle is 

 a most excellent pattern for both clear and pasty or thick liquids. The 

 degorger combined with it renders the spraying of the latter possible. 



Fig. 2. — The Vermorel Nozzle with Lance. — The hose is attached to the lance at H. C, stop-cock, 

 d, exposed end of the degorger ; at the other end of the degorger is a pin which may be made to pass 

 through the opening of the nozzle, clearing it when clogged. The degorger is pushed in by the rod R, 

 sliding through the fixed bearings b, b, b. The force of liquids under pressure will bring it back into 

 position.
