Fig. 1 is the Drawing-frame. It has a hatchel belt, c, with points and clearers npon which the rov- 

 ing lies, and a bobbin-belt, kk', like the belted roving machine, as will be seen by simple inspection, 

 page 372. It revolves in the same direction as in the roving machine, and has a binder pulley, d, to keep 

 it to a proper tension. The ends of the hatchel plates bearing the points of the hatchel rest or slide on 

 the tops of the rail f f ; the belt is kept in place by a plate, e, at the left end of the frame, a. g g are 

 plates of iron attached to the frame, called forcing plates, A tin tunnel, l, is fixed between these plates, 

 gg, for the purpose of directing the roving or sliver of hemp into the hatchel belt; this tunnel runs in 

 the direction of the dotted line between the forcing plates until it nearly meets the bobbin-belt.
