676 Report on the Trials of Implements at Taunton. 
Fig. 45. — Section of Messrs. TasJcer and Sons' Comhined Guard am 
Feeder, No. 707. 
It may also be useful to give an illustration of No. 3656, by 
Robey and Co., as a clever and ingenious attachment. The 
Judges considered that it worked well ; and it will be seen by 
the Table facing page 671, that less power was expended when 
in work with the feeder than without it ; but they did not 
consider it combined the essentials of a guard. 
Bdbey and Co.'s Self-feeder, No. 3656. — This feeder is a clevei* arrangement, 
which commanded the particular attention of the Judges, and, as will be seen 
])y the Table, worked very satislactorily as regards power; but it had small 
claims as a guard. It may be explained by the accompanying illustrations. 
A is the drum, B the concave of the threshing-machine, c c (Figs. 46 and 47) 
represent the fork-sliaft and forks receiving a motion backwards and forwards 
from a crank-pin, r>, on one arm of the shoe-pulley E ; o is a shaking-board, 
on which is placed the crop to be threshed. This board has a motion up 
and down, which it gets from an eccentric, ii h (Figs. 4Gand 47), on either end 
(if the shoe-shaft. The amount of motion which may be given to the shaking- 
board and forks can be regulated at will. A row of fixed forks,- i, are 
placed on a fixed board, to prevent the feed going into the drum Aister than 
required.
