Nozzles. The pump should be fitted with the kind of nozzle 

 best adapted to the work to be done. Generally speaking, the disk 



type, which breaks the liquid 

 into a very line mist and pro- 

 duces a short-distance, cone- 

 shaped spray, gives the best 

 results. 



Spray nozzles may be di- 

 vided, according to the shape 

 of the spray, into hollow-cone, 

 solid-cone, solid-stream, and 

 flat or fan-shaped nozzles ; but 

 for practical purposes it is bet- 

 ter to classify them according 

 to their construction as disk, 

 Vermorel, modified Yermorel,

self-cleaner, cap, Bordeaux, cyclone, and solid-stream nozzles. 



Different types of nozzles are suited to different kinds of work, 

 and as their efficiency sometimes depends upon the pressure, care 

 must be taken not to select a 

 nozzle which will be unsuited 

 to the machine with which it 

 is to be used. Some nozzles 

 are of very large capacity and 

 should not be used with pumps 

 whose capacity per minute is 

 less than that of the nozzle. 

 The disk nozzles, as compared 

 with most of the Vermorel 

 or self-cleaner types, have a 

 greater capacity, are more com- 

 pact, lighter in weight, less 

 liable to clog, and do not 

 have any projecting parts to 

 catch onto limbs and make 

 trouble. Although disk nozzles have been on the market for only 

 a few years, they are rapidly superseding the older and more 

 common types.
