The feed table (figs. 6, 8, and 9, G). — The feed table consists of a 
wood or iron frame 9J inches wide, running the entire length of the 
machine under the feed screw. It should be the length of the ma- 
chine from outside to outside of the end frames. The top of the 
frame is covered with a 10-inch board, which is cut into sections as 
shown in figure 8. These sections are held in place by some sort of

feed screw but with the teeth a little smaller. 
The adjustment mechanism (fig. 6). — The feed screw E is supported 
at each end by an iron bar H, attached at the lower end to a bab- 
bitted collar a on the drum shaft and held at the other end by a ver-

The hole in the iron bar H, through which the feed-screw shaft j 
extends, should be at such a distance that when the feed screw is in 
place there will be about one-half inch clearance between the edge 
of the screw flights and the drum. In case the machine is to be used 
a great deal, the bearing for the shaft of the feed screw at / in the
