Report on Miscellaneous Implements at Shrewsbury, ^"c. 11 
Along the bottom of the feeding-trongh is an endless band (a) fonned of 
pitch chain, with wrought-iron cross-bars forming the web. This endless 
band travels roimd a pitch wheel (d) close to and at the same level as the 
bottom feed-roller (f), and when in motion is very similar to the travelling 
feed in other machines. 
The upper feed roll (e) is carried in a movable casting, which casting also 
cames a pair of pitch chain wheels (c); these wheels drive an apron (b> 
which is mclined backwards from the feed-rolls to the top of the feeding- 
trongh, and extends to such a distance that the feed-rolls cannot be reachai 
by a man's hand.
