arm H should be reinforced by a babbitted bushing to prevent wear. 

 The short arm M is attached at the lower end to the same collar as 

 H, and the other end rests on the wheel nut N, running 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 M 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 

 Z as a pivot. It is essential that the center of the bolt /f 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 sizo to tum 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, Z7) 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 dehvered 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
