Report on the Trials of Implements at Taunton. 677 
The angle of the driving-gear of the shaking-board, g, and the forks c, is so 
, fixed that the board is lowered at the time the forks make a grab forward, 
and is raised as they come back, so that the forks return under cover. 
Let it be imagined that the hopper is filled and the machinery at work. 
When the forks c protrude through the board g as it lowers itself, they take 
hold of a portion of the feed and carry it down to the drum, the bent-irons 
J J (Figs. 46 and 47) guiding it properly to the drum. The board G then rises, 
and the crop is held by the fixed forks 1 1, while the moving forks c return 
under cover of the shaking-board to make a fresh grab. They make about 
200 grabs per minute.
