MEMOIR OF DANIEL TEEADWELL. 



The apparatus by which the hemp is carried in the drawing-frame and drawn to form a filament con- 

 sists principally of two steel rollers, ss, Fig. 4. The lower roller runs in gudgeons in the pillars fp, oo ; 

 the upper roller runs in gudgeons in two levers, qq, hung by pins forming fulcrums or axes iu the pillar 

 pp, Fig. 2. These levers are connected together by the curved iron bar, r, Figs. 2 and 4, so that one 

 cannot rise or fall unless the other rises or falls with it. The drawing -rollers ss are coupled by the 

 plates tt to the shafts uu, running in the pillars oo, and connected by the gear-wheel v v. x, Fig. 1, 

 is the gatherer ; this is made of plates of iron in nearly the form of an unequal four-sided pyramid, 

 with its open base towards the hatchel-points and its truncated apex opening between the drawing- 

 rollers, being so shaped as to conform to those portions of the rollers which are situated against it. 

 The top of the gatherer, y, passes off towards the bobbin-belt to receive the roving of hemp and direct it, 

 to the rollers. The top of the gatherer has several slits cut through it, so that the teeth of the comb, 8 6,

can pass through it. There is, moreover, in the gatherer a false bottom, hung by a joint at the end 



nearest the drawing-rollers and capable of being swung upwards like a trap-door. This false bottom has 



slits across it, corresponding with those through the top. In Fig. 4, a is a fast pulley on the shaft b, to 



which the power to drive the machine is applied, by means of a belt ; a r is a loose pulley on the same 



shaft, b, on which the driving-belt runs when the machine is at rest. On the end of the shaft b is the 



pinion c, which drives the wheel dd, fixed on the shaft u, which is coupled to the lower drawing- 

 roller, s.
