MEMOIR OF DANIEL TEEADWELL. 



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

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



" As it enters the machine, it lies ou a hatchcl similar to that already described, where 

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

 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 siiall 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 

 rovina- between the drawing-rollers and the hatchel-belt, and thus some of the fibres arc broken 

 off, and the advance of any loose fibres, that were drawn along by others in contact with 

 them, is interrupted. When by this means the yarn has become of the proper size, the comb 

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

 supply of the rollers." 



A full description of this machine, with the parts figured in detail, will be found 

 in Appendix I.
