PRODUCTION OF SWEET-ORANGE OIL. 19 
comes in contact with the rapidly revolving drum it tends to spin 
rapidly in the opposite direction, but this is sufficiently retarded by 
the toothed surface of the table, which supports it, so that it is 
acted upon by the teeth of the drum. The toothed nights of the 
feed screw tend to roll the fruit forward on the table, so that the peel 
is removed in a series of spirals. The peeled fruit is delivered from 
the spout W (figs. 6 and 7). 
In adjusting the machine for work the weight which the fruit 
presents to the drum can be changed by raising or lowering the arm 
H on the standard L (fig. 6). By means of the wheel nut P, the 
table can be inclined so as to increase or decrease the angle made 
with the drum. The smaller this angle is the more tendency there 
is for the fruit to be pinched against the drum and the more severe 
the grating action. The wheel nut N raises or lowers the arm M, 
so that the table may be kept at the proper distance from the feed 
screw. 
CHANGES REQUIRED FOR THE VARIOUS CITRUS FRUITS. 
The dimensions as given are those suitable for oranges or lemons. 
If it is wished to use this machine for peeling grapefruit a feed screw 
having flights of the proper size can be constructed and installed in 
the same manner as has been described. In the case of limes, the 
screw can be made smaller and shorter.
