THE GENESEE FARMER.

its level ; and to supply a constant and abundant 

 stream at any desired elevation, without the liability 

 to accidents and stoppages, has prevented inquiry 

 into the construction of the Hydraulic Ram ; and 

 consequently it has remained comparatively unknown 

 and, until within a few years, but little used. 



" The annexed cut represents a vertical section of 

 the Ram. A, the 

 air chamber : B, 

 the waste valve ; 

 C, valve opening 

 into the air cham- 

 ber ; D, the feed 

 or driving pipe ; 

 E, pipe to convey 

 the water whore 

 it is desired. The 

 pipe D should be 

 30 to 50 feet long, and from 1 to 2 inches calibre ; the 

 pipe E any length desired, and about half-inch calibre. 

 Lead pipe is commonly used. The circidar figure 

 on the left represents the form of the waste valve. 

 The waste valve is made to vibrate up and down 

 thus 1 'The water passes down the driving pipe D, 

 and escapes at the waste valve B. Now, as any 

 descending body increases in velocity and force every 

 instant of its descent, the column of water descending 

 in the driving pipe, quickly attains sufficient velocity 

 and force to lift the waste valve ; but the valve in 

 rising instantly stops the passage, and the wliole 

 momentum of the water strikes against it and seeks 

 relief, which is only found at the valve C, through 

 which a quantity of water is forced into the air 

 chamber, where it is confined by the closing of the 

 valve. The momentum being thus expended, and 

 the water at rest, the valve B drops by its own gravity, 

 and is ready to start again. After repeated vibrations, 

 the air chamber becomes partly filled with water, 

 compressing within a small space the air, which, by 

 its elasticity, re-acts upon the water, and forces it up 

 the pipe E to any desired elevation or distance." 



The following engraving gives a more digtinqt 

 view of the ram, in operation. 



H, spring or brook. C, drive or supply pipe, from 

 spring to ram. G, pipe conveying water to house 

 or other point required for use. A, B, D, E, I, the 

 Ram. .T, the plank or other foundation to which the 

 Ram is secured. 



The COST must of course depend upon the distance 

 the water is carried. Lead pipe, IJ inch, can be 



procured for about 15 cts. a foot. The price of the 

 Ram of a size fit for general use, is $25. 



For the accompanying engravings we are indebted 

 to W. & B. DouQLAS, the manufacturers, through 

 their agents at this place, Rapalje &. Briggs, of 

 whom Rams can be procured, as also at most of the 

 Agricultural Warehouses in the country. 



EMERY'S CYLINDER DYNAMOMETER. 



This instrument was invented the past season by H. 

 L. Emery, of Albany, N. Y., at great expense for 

 experimenting, altering, he, he, and as now made 

 and used, it is nearest the thing for its purpose yet 

 introduced. It has been used at several trials of 

 plows the past season, as well as in experimenting, 

 and has given ejitire satisfaction to the parties inter- 

 ested. It has been exhibited at the New York State 

 Fair at Syracuse, at the American Institute at New 

 York, and at the Worcester Mechanics' Association 

 at Worcester, Mass., and by each the inventor was 

 awarded a silver medal, with the highest encomiums 

 of their several committees. We cannot give a 

 better description, than to copy that of a committee 

 of seven of the best practical mechanics, machinists 

 and manufacturers, of tlie Worcester County Mechan- 

 ics' Association, in whose report they say that " no 

 article of any importance has received a mere cursory 

 glance, or guess, at its merits ; but pains have been 

 taken to test every article according to its claims ; 

 and we present not our own opinions alone, but with 

 them the facts on which they are predicated." 



" It is intended to be used as a comparative test of 

 the power required 

 to overcome the 

 resistance of bod- , 

 ies under draft, and \ 

 more particularly 

 that of plows. — 

 The usual spring 

 scale has many 

 faults, the chief of 

 which are its vi- 

 bration, and ab- 

 sence of self-deter- cylinder dynamometer, 

 mination of the maximum of the force exerted. This 

 invention remedies these faults. It consists of a 

 strong iron cylinder about eight inches long and two 

 and a half in diameter, into which a piston is ground 

 steam tight, the piston rod passing through the stuf- 

 fing box in the cylinder head, and receiving in its 

 end the draft ring, a strap hook or ring at the other 

 end of the cylinder, to serve as the attaching or con- 

 necting link, 



"It will bo seen that if the piston be sent back to 

 the end of the cylinder, and the space filled with 

 some non-elastic fluid that no force employed for draft 

 purposes could draw the piston out, and if a small 

 opening be made through the piston, so as to make 

 a communication with both ends of the cylinder, the 

 fluid will escape under the pressure and tlie piston 

 be drawn out in a given time with a given force. 

 This is the arrangement of the Dynamometer under 

 consideration, and a more simple and correct instru- 

 ment we have never seen ; and we recommend a 

 silver medal be awarded the inventor." 



A similar report, giving it the reputation of being 

 the best thing of its kind yet seen and examined, is 

 found in each of the published transactions of the 

 State Society and American Institute, for 1849.
