the liquid, and the outlet is disgorged by simply pressing the cap 

 down on the pin. Such are the Spramotor (Spramotor Mfg. Co.) 

 and Vapor-Mist Nozzles (Field Force Pump Co.) and are disgorged 

 rather more easily than those with springs. The Vermorel type 

 makes the finest spray of the three types of nozzles and will there- 

 fore be preferred for use with oils and fungicides where a very fine 

 spray is desired. The liquid must be thoroughly strained, for they 



are easily clogged. Usually two or 

 three nozzles are attached to a Y, T, or 

 ring, for orchard or shade tree work. 



Disk Type. An evolution from the 

 latter type has recently been brought 

 out in which the chamber has been 

 made much broader and flatter, thus 

 giving a very strong rotary motion to

the liquid and breaking it into a fine spray through a large aperture, 

 so that no disgorger is required. This is known as the disk type of 

 nozzle, and was originated by the Friend Mfg. Co., but is now sold 

 by all the leading pump companies in various forms under different 

 trade names. The nozzle is light, does not catch on twigs, and the 

 large aperture prevents clogging, even of unstrained liquid, and 

 allows the passage of a large amount of liquid, one of these 

 nozzles spraying as much as two or three Vermorels. This type 

 was designed for use with power sprayers, but will give good
