The use of pressure tanks instead of elevated tanks for supplying water under pressure is becoming more and more uni- 

 versal each year. The pressure tank is nothing more than a lieavy, carefully made air tight steel tank into which the water 

 Is pumped. When the tank is what is commoniy called empty, it is really full of air. Into this tank which is fuli of air water 

 is pumped and as the air cannot escape from the tank, it is gradually compressed until, when the tank is two-thirds full of 

 water, you have a back pressure from the air ecLual to that you would get from a tank elevated 100 feet. If a high-grade 

 tank like those furnished with our Invincible Outats is used and the connections properly made you will have to pump new 

 air into tank in very small quantities. The only reason for pumping air being to replace that which is absorbed by the 

 water and drawn off. To rei^lacc this air, different devices are used. Sometimes simply an air cock in the suction pipe of 

 the pump, or a Hydro-pneumatic Cylinder or a separate air compressor, which devices are listed here. The advantages of 

 a pressure tank system are its absolute reliability, its simplicity and as these tanks are either placed in a cellar or buried in 

 the ground, with the end extending into the cellar, the water is kept an even temperature, being neither very hot in Summer 

 or freezing cold in Winter; this is a big advantage in watering stock. It does away with the necessity of having' an elevated 

 tank in house which is undesirable or an elevated tank on tower outside, which is frequently unsightly and very liable to 

 freeze up in cold weather. 



THE FROFEB SIZE TANK TO SEIiECT. 



The proper size of tank depends upon the total water consumption and the method of pumping. If the pump is oper- 

 ated by electric motor where reliable current is available, a small tank will give comparatively good service. In a case of 

 this kind, we would suggest a tank with a total capacity of twice the usual daily consumption, although if an automatic 

 switch is used a tank witli a total capacity equal to the daily consumption will give good service. Where an engine is used 

 for pumping, we would suggest a tank of a total capacity of not less than twice the number of gallons used daily. In fact, 

 we consider it better to use a little larger tank than this. When you are pumping by hand, we would suggest twice as many 

 gallons capacity as the daily consumption; and, if pumping by windmill, a tank with a total capacity of from four to six 

 times as many gallons as are liable to be used daily. 



INFOBIilATIOIT BIi&ITE:. 



We would be glad to mail on application to any one interested in the installation of an InvinciMe Water Supply Outfit, 



of our special information blanks which will enable : 



gently recommend suitable equipment.

you to clearly give the information which will enable us to intelli- 



THE KIND OP PUIffiP TO SELECT AND PROPER POWER 

 TO OPERATE IT. 



While we show here two complete outfits which represent 

 installations which are very frequently made, it is impossible 

 to illustrate in the limited space available, combinations 

 which suit the requirements of every one. The depth of well, 

 the amount of water supplied by it, amount of water required 

 per day, the kind of power most convenient to use and many 

 other conditions make it necessary to give individual con- 

 sideration to each case. In order that we may properly ad- 

 vise our customers as to what thev should have, on the fol- 

 lowing pages will be found fully illustrated and described a 

 line of pumps, pumping windmills, engines and electrically 

 driven pumps which will meet all ordinary requirements. 



VERTICAIi AND HORIZONTAXi TANKS. 



Invincible tank 6 feet long and shorter are regularly fur- 

 nished tapped to set vertical. Longer tanlrs are regularly- 

 tapped horizontal. Any tanks, however, can be furnished wiHt 

 either vertical or horizontal tappings and this makes no dif- 

 ference in price of tanks. Wherever it is practicable to use a 

 horizontal tank we consider it preferable. 



The above cut shows a popular outfit where water is to be 

 pumped from shallow well, cistern or spring. Price of this 

 outfit as shown, not including piping, consisting- of 36"xl0' 

 tank, 134 H. P. Ing-eco Engine and No. 502 Bulldozer power 

 pump with air attachment, $340.00.
