drum, -with cover, as shown in the ilhistration. These can be carried 

 by a man and boy, wheeled in a barrow, or drawn through the orchard 

 or vineyard on a newly designed sledge of light draught. 



Its action is the " perfection of simplicity," being almost automatic. 

 Two or three movements of the lever fills the outer cylinder with highly 

 compressed air, which drives out a full head of spray for a minute and 

 a half. This allows the user sufficient time to effectually spray a large 

 tree. 



A boy of 8 years of age can keep up a full and continuous pressure 

 as well as a man. 



They are fitted with an universal joint which prevents kinking of 

 the hose pipe. 



When desired, they are made with a delivery hose, on either side, so 

 that two rows of trees may be sprayed at the same time. 



It is so constructed that it cannot get out of order or be easily 

 damaged. 



Fitted with a " Knowlesly Triune " patent nozzle, it is at all times 

 available as a powerful portable fire-engine capable of throwing a strong 

 jet of water a distance of fully 40 feet. 



It is, without doubt, the best spraying pump yet introduced. 



Price : £7 7s.

The Knowlesly Patent " Triune " Sprat Nozzle. 



This nozzle will prove a boon and blessing to fruit-growers. Should 

 the Knowlesly nozzle choke, which is seldom the case, it can with ease 

 be cleared in a quarter of a minute. 



The No. 1 throws three distinct sprays and jet. 1st, by removing 

 the cup from the inside; 2nd, by removing both cup and cap; 3rd, by 

 using both cup and cap. 



The No. 2 double spray nozzle will commend itself to all who use 

 spray pumps, as it adapts itself to the user's varied requirements. 



It can be used either as a single or double sprayer, as each nozzle 

 " shuts off " when turned downwards, yet sprays at any angle, and 

 will throw as much " Scotch mist " as can be utilized. 



Frice: Single 5s.; double 10s. Screwed to fit |in. pipe.
