c. Points where the threads run across each other to 

 clean their surfaces. 



d. Spiral groove, with a pin to give the traverse 

 motion to the thread, in order to spread it over the 

 reel e; the traversing bar moving horizontally to and 

 fro, in the arc of a circle. 



/. Pulleys, which transmit by cords the rotary move- 

 ment of the cylinder d, to the reel e ; the pulley con- 

 nected with the reel being the smallest of the two. 



g. Friction lever, for tightening or slackening the 

 endless cord, in setting or stopping the winding opera- 

 tion. There is usually a series of such reels in one 

 apartment, driven by one moving power ; but each of 

 them, as shewn, can be stopped at pleasure.
