MEMOIR OF DANIEL TREADWELL. 



The hemp, having been formed into a rpving by the machine just described, 



may now be passed into the spinning-machine, called a " Gypsey.

" As it enters the machine, it lies on a hatchel similar to that already described, where 

 every fibre is free to move in the direction of its length, without carrying any other fibres witl 

 it, whenever a proper force is applied for the purpose. The instruments by which this force is 

 applied are a pair of rollers, which are moved with a constant velocity. Provision is made in 

 the machine that, whenever the number of fibres between the rollers is too small to form a 

 yarn of the required size, the hatchel containing the roving shall advance and present a new 

 supply of fibres to the drawing rollers. This advance is made with a greater or less velocity,

corresponding in some degree with the quantity of the supply required. When, by the supply 

 thus given, the yarn has become of the required size, the hatchel ceases to advance, and 

 further, if the supply has become too great, a small hatchel or comb is made to pass into the 

 roving between the drawing-rollers and the hatchcl-belt, and thus some of the fibres are broken 

 off, and the advance of any loose 



fibres, that were drawn along by others in contact 



with 



them, is interrupted.

is made to rise from the roving, which may then be advanced as shall be required for the 

 supply of the rollers."
