PLANS FOR AUTOMATIC SPRAY APPLICATOR 



Most materials are indicated in diagrams. The 

 wind shield may be of plastic -coated screen wire 

 (as in working model) or other suitable material, 

 including burlap, canvas, or sheet iron. 



Sprayers used in working model are Cornelius . 

 (Any similar sprayer that delivers about 1/30 

 ounce per stroke may be substituted.) Intake line 



of Cornelius sprayer should be bent as shown on 

 page 8 to allow small check valve to fvinction. The 

 copper tubing from gallon spray container should 

 be soldered directly to sprayer intake line. Other 

 metal or oil -resistant plastic ( Tygon ) tubing may 

 be substituted for copper. With Z. & W. sprayer, 

 no tubing is needed, but gaxden-hose fitting should 

 be soldered near bottom of can as shown on page 8.
