306 Hydraulics for Farmers. [June, 



Ellsworth's Syphon Ram. 



This apparatus, invented by Eiastus W. Ellsworth, Esq., of 

 East Windsor Hill, Conn., is intended for elevating water from 

 springs, wells, and other sources, wherever sufficient fall of water 

 can be obtained in their vicinity, for the operation of a syphon. 

 In principle, it consists of a combination of the syphon with a 

 machine long known as the hydraulic ram; but is different in its 

 construction and mode of operation, from similar combinations 

 which have heretofore been attempted, and proved of little value 

 for practical use. It has now been operated a sufficient length of 

 lime to place its durability and utility beyond conjecture, and to 

 give it at least a tolerably fair title to the rank of a useful ma- 

 chine. 



One of these machines was put in operation by L. B. Arm- 

 strong, last fall, at the house of Mr. G. Harvey, at vSandy-Hill, 

 Washington county, the operation of which is described in a letter 

 to me, as follows: 



Dear Sir, — I comply with your request, made at the time I Avas 

 at the American, in September last, to inform you of the result of 

 my trial of Ellsworth's self-acting pump. I did not receive the 

 pump until some time about the first of October. The setting up 

 occupied about ten days: and when things were all right, off she 

 went, and has not stopped since; and what is more, it has not re- 

 quired a moment's attention from that time. The elevation over- 

 come is thirty-eight feet; the fall fifteen feet, of the longest leg 

 of the syphon. The amount delivered is half a gallon per minute, 

 about one-sixth of the water used. There are some little altera- 

 tions needed in the leather of the valves, which will add much to 

 (he effect of the syphon. But as the weather was cold av hen I put 

 up the apparatus, I did not seek to make the machine do its work; 

 and, considering certainty of operation through winter, without 

 stopping, more desirable than a large per cent of water raised, I 

 did not like to strain the pipes with the full power of the ma- 

 chine, as the quantity raised is more than is needed. For sixty- 

 seven sturdy knocks per minute, each one something like the blow 

 of a heavy mallet in the hand of a stalwart carpenter, " is a cau- 

 tion" io put down none but strong and sound pipes." 



L. B. Armstrong.
