616 Report on Miscellaneous Implement Awards at Derby. 
The band-frame is made of wrought-iron bars riveted to 
wrou£rht-iron rings. The feed-end or head is constructed of 
Avood, and is made like two heads screwed together, so that the 
cylinder slips over one and butts against the other, and thereby 
makes the joint secure. An iron bracket, screwed to the head, 
forms the centre-bearing for the spindle. The ring at the 
delivery end is made of cast iron, with the boss out of the 
centre, which gives the eccentric motion to the spindle. The 
cylinders are made of perforated iron, riveted together ; they are

readily slipped on to the frame, and secured to the wood head 
by screws. The iron bars of the barrel-frame act as lifters to 
the corn, and help to keep the corn in motion whilst it is in the 
barrel. The round-hole cylinders are corrugated, to further aid 
in this movement. The cleaner consists of a thin wooden rod, 
covered with a spiral wire ; it is kept in place by cords attached 
to the two ends and to the wooden frame. The cords allow great 
freedom of action to the cleaner, rendering its action very efficient, 
without much friction. The reason for corrugating the round- 
hole barrel and not the long-hole one is that the latter is much 
more difficult to clean, and requires the cleaner to touch all the 
way round ; whereas in the round-hole barrel the vibration of 
the cleaner over the uneven surface is quite sufficient.
