James Regulating Tank A 



For Cups Types 4 and 5 



(PATENT APPLIED FOR) 



It keeps the water constantly at the right level in the drinking cups. Takes up very 

 little room. It is sensitive to the slightest outflow of water from the drmking cups, 

 marvelously quick m feedmg more water when the level of water in cups is lowered ever 

 so little, and m shuttmg off water when cups are filled. 



With the James regulating tank on the job, your cows are assured a full supply 

 of water, day and night, even though all may be drinking at the same time. It will feed 

 all the water the pipe will carry, or a drop at a time, just as the cows drinking water 

 from the cups may require. 



The greatest obstacle to the success of drinking cup systems heretofore has been the 

 lack of a satisfactory regulating tank — one that is trouble proof and that would maintain 

 a constant supply of water in the cups. 



The James regulatmg tank is wonderfully efficient, its great success being due to an 

 ingenious self-balancing valve which accommodates itself to varying water pressure, working 

 with the same certainty and uniformity on two pounds water pressure as it does on 

 fifty pounds. 



With your regulating tank so located that its water level is the same as the level 

 desired in the drinking cups, neither cups nor regulating tank can overflow. 



It requires such small space that it may be located under a stall partition, if desired, 

 as shown on page 1 74, either at the end or in the center of a row of stalls. It will 

 not interfere at all with the comfort of the cow. 



Drinking Cups for Pressure System 



James Drinking Cup Type 3 



(PATENT APPLIED FOR) 



The cup IS Simple, consisting merely of the smooth surface cast iron cup, with non- 

 rusting trouble-proof inlet valve, and controlling lever (by pressing which with her nose 

 the cow opens the valve while drinking.) 



The valve is kept closed not only by the pressure of the water but also by a coiled 

 spring (of non-rusting spring brass), and there is no chance for water to flow back from 

 one bowl to another. This prevents any possibility of spread of disease. 



Easy to Clean 



The cup is easily removed from the stall post, by simply tripping the supporting lever. 

 The water may then bs dumped out of the cup, valve lever lifted out and the cup 

 cleansed or sterilized. It is just as simple a matter to replace the cup. The illustrations 

 on pages 1 70 and I 76 make very clear the construction of the cup, its simplicity and 

 the ease of removing from the stall post and cleaning. 



Installation 



The upright pipe connecting the cup and the feed pipe is shipped with supporting 

 lever and valve attached, making installation very simple. 



The pressure system requires only one size pipe and fittings, %-inch throughout. This 

 pipe fits neatly against the floor and curb entirely out of the way. Or it may be so 

 installed as to feed from above.
