A Few Points on Automatic Water Supplies for Irrigation, Mining and Town Water 



Notwithstanding that a properly con- 

 structed and installed hydraulic ram has the 

 highest efficiency for converting a given 

 hydraulic power into work, in the way of 

 automatically elevating water to a height 

 considerably greater than the fall from point 



of intake to location of engine, yet, this de- 

 vice is often overlooked when considering 

 the problem of an economic and dependable 

 water supply. This is probably due to the 

 fact that the ordinary hydraulic rams pos- 

 sess certain defects in construction, which, 

 although not important in plants of small 

 capacity, are naturally increased in large en- 

 gines in proportion to their size so that 

 their construction has been heretofore 

 limited in capacity. 



The accompanying cut illustrates a Ni- 

 agara hydrokinetic engine which is es- 

 pecially designed for installing where large 

 quantities of water are desired. They will 

 take from a minimum of 400 gallons to a 

 maximum of 12,000 gallons per minute to- 

 ooerate them, and will work under a head 

 of from 18 inches to 50 feet, elevating 

 water 35 feet high for each foot fall. The 

 quantity delivered, of course, depends on 

 the difference in ratio between the number 

 of feet fall under which the engine is in- 

 stalled and elevation from it to point of 

 delivery, the maximum elevation being 800 

 feet. The working expenses are purely 

 nominal as they consist in the renewal of 

 two comparatively small rubber rings and 

 painting once every twelve or thirteen 

 months. 



If readers of Forestry and Irrigation 

 are interested in this engine, the under- 

 signed will take pleasure in sending them 

 full particulars on the subject.
