the pirn O, fo that as the yarn is let off from the reel N, 

 it is regularly winded up on the pirn O, fo as to be fit for 

 being put into the loom for weaving. It is fcarcely necelTary 

 to obferve, that this yarn may be winded at pleafure, either 

 upon bobbins having ends to each, or pirns fit to be put into 

 the weavers fhuttle, as fuits the purpoie intended to be made 

 of it. 



Thus, by a very fimple apparatus, the yarn may be at one 

 operation, and at very trifling expence, untwifted to any de- 

 gree that flial! be thought proper; reeled, fo as to alcertain 

 its quantity precifeJy, and done up again upon pirns, or bob- 

 bins, fit for either warp or woof, -vVithout being ever touched 

 by the hand, or taken from the reel in form of fcains, an ope- 

 ration (the making up into (kains) that, with Hack yarn, is al- 

 ways produdlive of mifchief. 



This little apparatus is fo plain and fimple, that the above 

 dtfcription will be altogether fufficient, and give a complete 

 idea of its principle. To give a perfedt notion of fome leffer 

 particulars, would require many words, which would only 

 tend to embarrafs readers, without a great number of plates ; 

 among thefe particulars are — the contrivance for lifting out 

 the bobbins F F at pleafure. 



The fame for taking cut and putting In the pirns H H K, 

 and for putting the thread, without breaking it, through the 

 hole in the middle of the checks that hold the axie of thefe 

 pirns. 



The fame for taking out the>bobbins III at pleafjre. 

 ' Alfo a contrivance for laying the yarn upon the reel K, fo 

 as to prevent one thread from ever finking through among the 

 reft, fo as to be entangled, or to have the end loft, flaould it 

 break, as well as to prevent it from rifing into heaps upon 

 the reel ; and a fimilar contrivance for laying it regulaily up- 

 on the pirns, or bobbins O O, as it is winded upon them ; and 

 laftly, the apparatus, that has been before but flightly mention- 

 ed, for communicating the neceffary motion to the pirns by 

 means of the (heevcs PP. 



A diftindl notion of thefe particulars could be beft convey- 

 ed to manufafturers, by having a machine of this fort actually 

 made, and exhibited to them in a working ftate, fiom which 

 as a model others could eafily be made.
