THE GENESEE FAEMER. 



^^ 



internal gearing of the powers themselves, it becomes neces- 

 sary to take that difference into our calculations, -which we 

 find as follows: The cylindi-r when attached to Emery's 

 power, revolves 9.15 times per each foot of platform— with 

 Badger's, it revolve<ir.l5 to each foot— and Westinghouse's 

 revolutions 10.67 times. Thus showing that Badger's pow- 

 er geared 27 per cent slower than Emery's, and 48 per cent, 

 slower than Westinghouse's, and should produce results 

 bearing a relative proportion of increase over them. 

 Emery's, therefore, as compared with Badger's should 



house's, should have produced 2,061 revolutions, while he 

 did more by about 9 per cent. 



These minutes are copied from the report, but the deduc- 

 tions are not. They are themselves, self-evident, notwith- 

 Btanding the report to the contrary, which reads : 



"From the foregoing table, (alluding to velocities and 

 distances) it is obvious Badger's power works with the least 

 friction, or that gravity gives to bis machine a greater 

 amount of useful power than to either of tlie others on trial 

 being 3 per cent, more than Emery's, and 55 per cent, more 

 than Westinghouse's." 

 It further says : 



" Badger's power is well made, and in this respect de- 

 serves much credit ; yet in this excellence it is exceeded by 

 Emery's." . 



•' Badger's is a rack and pinion power, the legs being 

 connected by strong iron links, and the rack though straight, 

 is provided with teeth increasing in depth as they approach 

 the exterior edges of the plates into which it is divided ; 

 and each plate is perforated in the center, to accommodate 

 the convexity of the pinion while passing over it. This 

 perforation weakens the pieces, and increase their liability 

 to fracture. A rubbing action seems to be inevitable, caus- 

 ing rapid wear." 



Justice to the Emery power in this last experiment re- 

 quires the statement of the fact, that it was made at Utica 

 some two months subsequent to the Geneva trial, and not 

 with the understanding with the competitors, that it was to 

 be made a part of the report; and while this power was 

 transported from Geneva to Albany, and back to Utica by 

 railroad, it became filled in all its gearings with coal and 

 cinders from the locomotive, being on an open car. It be- 

 came necessary to take its every part to pieces, and was 

 cleaned as well as could be done under the circumstances 

 — while both the others were different powers than used at 

 Geneva— one being brought by wagon, with great care, to 

 Utica, and the other in a box car by railroad. This is nam- 

 ed to show the cause of the relative difference in the trials 

 of friction at the two places. This fact was made known at 

 the time to the committee, but it is not noticed by them. 



The One-horse Powers, which were transported in tight 

 cars, suffered no inconvenience from coal and dust, and the 

 results were as follows : 



Emery's, with two men, travelled 104 feet, and produced 

 950 revolutions per minute. 



Badger's, with two men, travelled 87^^ feet, and produc- 

 ed 630 revolutions per minute. 



According to the gearing, as before. Badger's should have 

 produced about 1,2.'50 revolutions to have equ.alk-d Emery's 

 — Irat came nearly 50 per cent, short of this stan<lard. 



Where has the report, as published, noticed this discrep- 

 ancy in the One-horse Powers? No where. It simply 

 gives the number of revolutions, without a comment. Is it 

 such a report as the statistics justify, or is it not? 



Another experiment was made with each set of powers 

 connected with threshers as in use, and six men placed on 

 the several platforms, weighing 925 lbs., and the velocity 

 allowed to equ.ilizo the power or weight on the platform, 

 and this velocity noted for one minute, as follow.s— (rather 

 an ambiguous method of reporting, to say nothing of tho 

 errors) : 



Badger's power, 150 revolutions of wheel, 10 in. of plat- 

 form to each revolution =197 ft. gaining perpendicular of 

 44.32 ft., for 282 lbs., while it should read- 

 Badger's power, 1.50 rev., 10 in. each for platform=125 ft, 



equal to raising 925 lbs. 28.11 ft. perpendicular besides its 



own friction. 

 Emery's power, 140 rev., 10,';; in. each for platform,=207 ft. 



equal to raising 925 lbs. 46.56 ft. perpendicular, besides its 



own friction. 

 Westinghouse's 256 rev., 7?^ in. each for platform, =152 fl., 



equal' to raising 925 lbs. 34.19 ft. perpendicular, besides its 



own friction. 



If this shows anythirtg, it is that the Emery power and 

 thresher combined, runs much more easUy than either of the 

 others. 



Another experiment was, to place two men upon the 

 platforms of the Two-horso Powers without threshers or 

 steelyards, and allow the velocity and power (232 lbs. on 

 platform) to equalize each other, and note the distance Ira- 

 velled— with the lollowing result : 



"Badger's power 218 rev., 10 in. each,=286 ft. of platform, 

 perpendicular elevation of 45.69 ft, for 52.25 lbs. 



Supposing the 286 ft. to be correct, (which should be 190 

 ft.) the elevation would be 64.68 ft. — while it should read 

 thu.s — 



Thus showing conclusively the great difference in the 

 friction of the powers themselves, as also with threshers at- 

 tached, is in favor of the Emery power. 



The next experiment is that of threshing grain with hor- 

 ses weighing 2,200 lbs., placed upon the several platforms, 

 and a quantity of grain, 100 sheaves, weighed off to each 

 competitor. 



The travel of the horses, the time occupied, the weight of 

 grain obtained, the velocity of the cylinders during the 

 threshing of the grain, the number of men required, &c. 



From this table we obtained tho following deductions, 

 which will show tho relative cost of threshing with the end- 

 less chain powers with great accuracy, as the experiment 

 was tried with every circunistanco alike with each, and in 

 a manner where there was no possibility of favoriteisin nor 

 deception — as tho whole work was done by tho gravity 

 alone, and each machine ne^v, amd horses not before used 

 on any power.
