pcrmitft tlic spindles to revolve with 

 greatci' velocity. 



The invention of an improved me- 

 tliod of preparing and spinning the 

 materials, which he professes to ope- 

 rate upon, docs not depend so much 

 on the introduction of new parts or 

 new processes, as upon the improve- 

 ments which he has made on those 

 already in existence, and his general 

 comhiuatlon of them, by which lie is 

 enabled to produce, as hereinbefore 

 stated, the most delicate roving, or the 

 strongest yarns or threads. Mr. M. 

 lias jiroduced a new machine, or com- 

 bination of machinery, which in prac- 

 tice will be found capable of producing 

 rovings, yarns, and threads, of better 

 quality, and in greater quantities in 

 cqualtimes, than could be done before ; 

 and, likewise, by his construction 

 the spindles may be made much 

 lighter for the same work, by which 

 much less power is required for the 

 whole machine, and wliich, conse- 

 quently, constitutes a new and useful 

 invention to the public. — Repertory. 



To Joseph Clisild Daniell, of 

 Frame, Clothier ifor certain Improvc- 

 nlciits in dressiiifjf Woollen Cloths, also 

 in prepftriiiff and using Wire-Curds as 

 applica'ile to that Purpose. — July 

 17, 18IU. 



These impiovemcnls consist of tliree 

 jiriiicipb's. 



The first principle is the grinding, or 

 reducing, the extremities or ends of 

 the wires or teeth of cards, (being im- 

 plements of trade, composed of wire 

 set in leather), used for the purpose of 

 dressing tir raising the piles on woollen 

 cloths to a picked point, or reducing 

 them as tending or inclining to a 

 picked point, which is performed by 

 means of a roller fixed on an axletree. 

 The second principle is the applying, 

 or using, for the purpose of dressing 

 or raising the pile on woollen cloths, 

 in machines called gigs (used in the 

 «loathing mamifaetiire), pointed Mire- 

 cards, or cards with the extremities or 

 ends of their teeth or wires made 

 picked, and the applying or using, for 

 the said purpose of dressing or raising 

 the pile on woollen cloths, cards with 

 their extremities or ends of their teetii 

 reduced or made smaller, or tending or 

 inclining to a picked point, otherwise 

 than what is produced by grinding 

 cards on a strickle roller, or on a steel 

 roller cut on its surface like a fde, or on 

 or with a stone ; by either of which 



[April 1, 



means the ends or ext?emities of the 

 teeth of the card would be ground 

 flat, not tending or inclining to st 

 picked point, as is commonly prac- 

 tised ; also for applying, or using for 

 dressing, or raising the pile on woollen 

 cloths by hand (commonly called hand 

 dressing) such pointed wire-cards, or 

 cards with the ends or extremities of 

 their teeth reduced as before-de- 

 scribed, or using pointed wire set or 

 fixed in any other substance instead 

 of leather, as applicable to dressing or 

 raising the pile on woollen cloths by 

 hand, likewise applying or using wire- 

 cards for the purpose of dressing or 

 raising the pile on woollen cloths, 

 with their teeth or wires made of 

 greater length than the teeth or wires 

 of cards hitherto used, for the said- 

 purpose of dressing woollen cloths, 

 which gives them greater elasticity, 

 and will be found necessary when the 

 ends of the teeth or wires of cards are 

 pointed or reduced. 



The third principle is the heating 

 woollen cloths after the wool or pile is 

 raised by dressing, and before the 

 cloth is racked or dried, for the pur- 

 pose of producing a fine and more du- 

 rable lustre, closing the texture of the 

 cloth, and giving it a soft handle, 

 which he performs by winding the 

 cloth smooth and tight on a roller, 

 while it is quite wet, after it is finished 

 raising, and the wool smoothly laid on 

 Iho face ; it is then put into a furnace 

 (made of a sufficient length to admit 

 the roller with the cloth on il), and 

 completely covered with water, which 

 water is to be heated by means of afire 

 under the furnace in the usual manner. 

 I'he cloth is to remain in the furnace 

 until it is hot in every part ; it is then 

 taken out of the furnace, and suffered to 

 get cold before he takes it olf the roller, 

 when it will be fit to be dried; care 

 must be taken that the wool on the 

 face of the cloth is not rufllcd or disor- 

 dered in winding on the roller before 

 it is heated.
