584 ANNUAL REPORT OF THE Off. Doc. 



even if you use the straight nozzle; that is by using this bent crook, 

 attaching this crook and (hen ])utting the nozzle onto the crook. 

 You get the same eU'ect. 1 want to show you now another nozzle. 

 Most of you have had the expeiience of holding a heavy spray rod 

 and a heavy brass nozzle at the })oint out at the end and have real- 

 ized 3'ou wished you had something lighter, and that brought forth 

 one that is made of aluminum. As a matter of fact, the importance 

 of that aluminum is not as great in my mind as anthei- point. Those 

 of you who have done very much spraying know this, that in spray- 

 ing up high, you not only have the weight of the rod bearing down 

 on your hand, but you have the reaction or the back pressure of that 

 immense force that is going to force that out, but when spraying 

 down you have just the opposite. You know you can hold a ten- 

 foot rod in one hand like that, when spraying down because there is 

 sufficient back pressure there to balance the weight of that rod, and 

 you can hold it with one hand when spraying in that direction. 

 When you turn it, you have the other way, not only the weight of 

 the rod, but the back i^ressure pulling it down. There is another 

 matter w^hich I think is very important in the matter of appliance. 

 In the days when you were satisfied with 85 or 100 pounds pressure, 

 hose attachments were not important, because the pressure was not 

 sufficiently great, and you could hold that hose upon the spindle 

 very easil}^ with the ordinary garden hose clamps. The important 

 thing was to have a sufficiently long attachment, but now we have 

 been using 200 pounds or more of spray, and you get it in the eye 

 or down the neck Avhen this thing breaks loose some day, and it will 

 simply enforce upon you more clearly than 1 can the importance of 

 having everything tight. 



Answering the demand of the fruit growers, many of our best 

 manufacturers of spraying machinery have manufactured something 

 which is a big improvement, I think, over the common garden hose 

 clamps. It is made of two cast brass clamps with two good, heavy 

 screws to hold them together. Now, with a long nip})le, with any- 

 thing as long as that entering the hose, you see you have the full 

 length for clamping, and this is something all ought to have. 



Question: Doesn't that have to be made with a special coupling? 



ME. BASSETT: Yes, the coupling has a shoulder. Those are cer- 

 tainly, I consider, one of the most important things. 



Another thing which any of you who hold the nozzle and hold 

 the spray will ajjpreciate, is one of these drip guards, a rubber at- 

 tachment which you slide on your bamboo pole, for the purpose of 

 catching any drip. There ought not to be any drip, birt lots of things 

 occur that ought not to orcur. and sometimes you will get some drip 

 from the attachment. One of the advantages of these nozzles lies 

 in the fact that they have a large capacity, do not often clog, be- 

 cause the hole is quite good size, and they certainly answer the pur- 

 pose better than anything else that I know of. The advantage in 

 this aluminum one is not alone in its being aluminum. The wearing 

 parts are steel. The disc is backed by a rubber gasket, but the in- 

 terior part is hard rubber. This part which causes the whirling 

 motion is on the same plan as a turbine water wheel. The im])ortance 

 of that is not only its lightness, Avhich I think is exaggerated, be- 

 cause, as I say, the reaction of the pressure will readily lift it, but
