REPORT OF JUDGES 



ON 



PUMPS AND HYDRAULIC APPARATUS. 



To the Board of Ifanagei'S : 



Gentlemen. — The undersigned, judges of Group 2, Department 5, 

 submit the following as their full report : 



Direct- Acting Steam Pumps. 



In this division there were three competitors, to wit. : 



No. 566 Steam Pump, Knowles & Sibley, Warren, Mass. 



E'o. 729 Steam Pump, C. B. Hardick, Brooklyn, New York. 



No. 755 Steam Pump, Geo. F. Blake, New York City. 



These pumps are all of the class technically called direct-acting 

 steam pumps, in which the use of a crank and eccentric are entirely 

 dispensed with, the piston and plunger being attached to the one rod, 

 and the motion of the steam valves taken from the action of the 

 same. 



At the Thirty-seventh Annual Exhibition of the American Insti- 

 tute, held in 1867, a practical test, by experienced gentlemen, was 

 given to two, among others, of the pumps upon which we are now 

 called to decide, to wit, the Hardick or Niagara pump and the 

 Knowles pump. Inasmuch as the judges made a test at that time 

 they were obliged to abide by such test and give their decision accord- 

 ing to the facts developed. 



In arriving at our conclusion, in the present case, we have not dis- 

 regarded that test, but, on the contrary have given it full and careful 

 consideration, and in view of it, and the further facts before us, our 

 finding must necessarily be different from that of the judges at the 

 said exhibition of 1867. 



"We desired to have a practical test this year, and especially so 

 because a new direct-acting pump, at least one new to us, was in the 

 list for competition, namely, the Blake pump. But we found tliat, 

 in view of the lateness of the time at which we entered upon our
