lutions per minute ; b shows 12 spikes, riveted into each roller in four rows, 
at an angle of 45°. c c are two rows of fixed iron spikes, 9 iu each row, 
screwed into iron rails on the back of a loose frame F, adjustable in slots, 
so as to vary the room when required. The rollers are driven by gearing, 
shown in Fig. 44, by a strap from the shaker-spindles ; from the end of the 
top-roller spindle a bevelled-wheel drives a bevelled-pinion and connecting- 
rod, giving motion to the knife k (Fig. 44), making eighty strokes per 
minute. It will be seen that the feed-board h is tilting, so that when pressed 
down and the hood is closed, there is an opening at the front to allow for 
sweeping down any loose com into the feeders. The knife k effectually cuts 
the bands of the sheaves.
