COTTON. SPINNING 



It will now be perceived, that these parts being all adjusted to accommodate the 

 taking up movement* to the twisting or spinning of any particular quality of yarn 

 intended to be produced, any variations between the velocities of the spinning and 

 taking up, which another quality of yarn may require, can easily be effected by merely 

 changing the pinion v for one with a different number of teeth, which will cause the 



wheel m, and the pulley box k, to drive the bobbins faster or slower, as would bo 

 required in winding-on fine or coarse yarn, the speed of the twisting or spinning being 

 the same. 



The bobbin and fly frame as thus detailed is now no longer constructed ; but it 

 seemed desirable, if not necessary, to describe with some minuteness a machine which
