18 BULLETIX 399, U. S. DEPARTMENT OF AGEICULTUEE. 
arm H should be reinforced by a babbitted bushing to prevent wear. 
The short arm 31 is attached at the lower end to the same collar as 
H, and the other end rests on the wheel nut X rumiing on the rod 
which is secured at the upper end of the arm H. By means of this 
wheel nut the outer end of the arm 31 can be raised and lowered. 
The feed table is supported by an iron arm attached underneath 
and forming a brace to hold the parts of the frame in position. 
This arm is carried up to the level of the top of the table and bent 
at right angles to extend in the same plane as the top of the table. 
At K this arm is secured by a bolt to the arm M and is then bent 
upward at right angles, forming the lever 0. At the top this lever 
receives the iron rod and rests against the wheel nut P. By means 
of this wheel nut the incline of the table is changed, moving on the bolt 
K as a pivot. It is essential that the center of the bolt iT should be 
in the same plane as the surface of the 
drum and so arranged that the inside edge 
of the slides forming the top of the table 
should be about three-eighths of an inch 
from the drum. 
The shaft of the drum should be fur- 
nished with a pulley of 8-inch face, of the 
proper diameter to drive the drum at 600 
revolutions per minute. The feed screw is 
furnished with a large sprocket wheel and 
driven by a small sprocket on the drum 
fig. lo.-cross section of the shaft, of the proper size to turn the feed 
screw at 150 revolutions per minute. 
The peel receptacle. — Underneath the drum is a trough made of 
tin or galvanized iron to receive the finely divided peel. This trough 
extends nearly to the floor and toward the front of the machine to a 
vertical line from the outer edge of the feed table. The back of the 
trough extends upward to the top of the frame and to it are attached 
removable covers which entirely inclose the drum and feed screw. 
These can easily be removed for cleaning and for removing the peel 
which adheres to them. 
OPERATING THE MACHINE. 
The fruit to be peeled is placed in a large box (figs. 6, 7, and 9, T), 
the bottom of which is a few inches higher than the top of the drum 
at the lower end. From this box a narrow spout (fig. 9, T) extends 
to the edge of the feed table. The fruit rolls into this spout and is 
fed by hand, one at a time, between the two lower flights of the feed 
screw (see fig. 9), one being delivered at each revolution of the feed 
screw. The fruit is carried along by this screw in contact with the 
drum, which removes the peel by grating. As soon as the fruit
