fruit may roll into the various compartments. The bin should be 

 large enough to contain stock for a day's run ; dimensions of 20 by 8 

 feet with a height of 6 feet will permit this, yet give sufficient room 

 for placing the grader above it. 



A very simple device serves to deliver fruit automatically from 

 the bin to the paring machines. Each compartment of the* bin is 

 provided with a false flooring inclined from all sides of the compart- 

 ment to the center, thus forming a flattened hopper. From the center 

 of each hopper a wooden chute 10 inches square passes through the 

 floor, runs with a downward inclination of 1 or 2 inches per foot of 

 length across the ceiling of the first-floor workroom to a point above 

 the paring table, and descends vertically to end in a box placed 

 beside the paring machine. A sliding door near the lower end of 

 the chute enables the operator of the machine to fill the box as it 

 becomes empty. If desired, the main chute may be divided, so as to

supply two or more machines from one compartment. As the chutes 

 are near the ceiling and over the worktable, they are out of the way. 

 This arrangement has the obvious advantages that there need be no 

 stoppage of machines because the supply of fruit is exhausted, the 

 workroom is not obstructed by boxes of fruit waiting to be worked 

 up, and the time of two or more men which would otherwise be spent 

 in getting fruit ready for paring and distributing it by hand to the 

 paring table is saved. The only expenditure of power is that neces- 

 sary for running the elevator and grader. The entire arrangement 

 is made clear by Figure 8. 



The worktable. — The table at which the peeling and trimming are 

 done is located in the first-floor workroom in the position indicated 

 in Figure 4. It is placed 6 feet from the wall separating the work- 

 room from the furnace rooms, thus giving ample room for passage 

 behind it without interference with those working at the table. In a 

 4-kiln plant the table should be 54 feet long, thus allowing 4^ feet
