The tail flour as it falls, is guided into the elevator to
ascend with the meal, and that a proper quantity may be
elevated, there is a regulating board R, set under the
superfine cloths, on a joint x, so that it will turn towards
the head or tail of the reel, and send more or less into the
elevator, as may be required.
There may be a piece of coarse cloth, or wire, put on
the tails of the superfine teels, that will let all pass through
except the bran which falls out at the tail, and a part of
which is guided into the elevator with the tail flour, to
assist the bolting in warm weather; the quantity is regu-
lated by a small board r, set on a joint under the ends of
the reels. Beans may be used to keep the cloths open,
and still be returned into the elevator to ascend asain.
What passes through the coarse cloth or wire, and the
remainder of the bran, are guided into the reel S, to be
bolted.
