to the spindle than the best ring bobbin known to him in use, and 

 with a saving of two-fifths of the power. That it will spin 100 per 

 cent more yarn than the flyer spindle, with one-half the power com- 

 pared to the quantity in use, being tapered to the top, and there be- 

 ing no bobbins or check pins used, it maintains its balance at any 

 speed required. It is not liable to get out of order, and is much 

 more convenient to piece up the ends when broken, than the bobbin 

 frame. The Messrs. Dodges represent their entire mill as having 

 been changed from the old or common plan to the above method of 

 spinning, and from twenty-nine years practical experience with othci 

 spinning, believe it to be the best kind of spinning in use. That they 

 are daily producing more yarn from 2,320 spindles than they w^ere 

 ever able to do from about 4,600 on the old plan commonly used. 

 That they are prepared to demonstrate the facts above stated, and 

 many other advantages in this method of spinning over all others in 

 use, and ask the privilege to do so. They have exhibited a compara- 

 tive statement of production to us for nineteen successive weeks of 

 their mill from January to May, 1849, compared with the old plan 

 for the same period of time in 1847, 1848. Also a comparative 

 statement of the cost of production for the said period, which results 

 in a saving or gain in favor of the Cop spinner of 42 per cent. Thai 

 it costs one cent per spindle for tending warp frames, and one and 

 one-eighth cents for filling frames, find twelve dollars extra for doff'ers 

 per week. 



Such are the claims of the inventor This machine was in opera- 

 tion during our twenty-second Annual Fair, and sustained itself well 

 in the estimation of those competent to judge the merits of this kind 

 of machinery. It was a full size frame, exhibited to the committee 

 in full operation, spinning warp yarn on one side, and filling on the 

 other. No. 31, and running at a speed of 124 revolutions of the front 

 roll. In a word, the frame performed well, made good yarn, wound 

 a good cop, and worked with perfect precision, and in the opinion of 

 the committee justified the expectation of the inventor ; that at no 

 distant day the attention of the manufacturing community would be 

 turned to it. The committee of judges to whom it was referred, re- 

 turned the following report :
