 a good one. We have not yet seen it tested. 



agitators. 



Agitators are of either (i) the mechanical or (2) the jet type. 

 The former have the greater variety of forms, the wider use and 

 in most cases the greater efficiency. 



Mechanical agitators are of the dasher type or of the whirling 

 paddle type. In barrel outfits the dasher type is most frequently used 

 but with large tanks the whirling paddle type prevails. 



Dasher agitators. — The dasher forms work up and down or side- 

 ways or both ways. Those which work up and down are used in 

 the larger number of barrel outfits. They are attached to the pump 

 handle and operate in close proximity to the end of the suction pipe. 

 An objection to them is that they do not keep the liquid equally well 

 mixed throughout the barrel. Of this type are Goulds' Standard, 

 Spramotor (Fig. 27), Hardie (Fig. 26), Defender (Fig. 22) and 

 Myers' barrel agitator. 



Similar in principle and attachment are some of the dasher forms 

 which work sideways. These are Goulds' Fruitall, Pomona (Fig. 

 25) and Savelot, the Field Force Pump Co.'s barrel agitator (Fig. 

 21), and the agitators used in some of the horizontal half-round 

 tanks. 



Up and down and sideways actions are combined in the Eclipse 

 (Fig. 23) and Deming agitators. The Eclipse agitator is a brass 

 spoon-like paddle. The Deming (Fig. 20) is simply three separate 

 paddles actuated by a common rod, one paddle working up and down 

 and the other two sideways. Among the dasher agitators this last 

 class is the most efficient. 



Whirling paddle agitators. — One form of the whirling paddle type 

 is illustrated by the independent revolving agitator (Fig. 15), which 

 was devised bv Mr. C. K. Scoon of Geneva, and first brought to the
