forming continuations of the slots in the tube
on which they are mounted, and are held to-
gether in this position by a narrow band driven
onto each end, so that when necessary these
bands may be driven back and the brushes
removed to be cleaned or renewed.
During the operation of ginning, while the
lint,passes from the rollers b to the brush-cyl-
inders d, and thence to the comb e, it is sub-
jected to a continuous and powerful blast issu-
ing from the slots between the brushes, which
removes all the motes and other impurities
from the fiber, and discharges them through
the wire grating q in their rear, so that when
the lint is blown from the comb e into.the re-
ceiver it is thoroughly cleaned as well as
ginned. The blast for these purposes is ob-
tained from a fan, o, or other suitable device
erected in a convenient position contiguous to
the machine, and is conducted to the several
parts through flexible or other tubes, p p'.
The advantages of this gin over all others
are, first, in the regularity of the feed. The ma-
terial being kept up to the rollers by a blast
of air is more regularly supplied than it, could-
possibly be by hand, in which manner it is
often pushed in in matted masses, whereas in
this the'fiber of the cotton, being the lightest,
is'first blown to the rollers, and by them drawn
through, leaving the seed behind, instead of
mashing and grinding a considerable portion
of it. Secondly, in the continual cleansing of
the rollers by the revolving brushes working
against them to prevent the accumulation of
any oily or gumriy extract from the cotton
bolls or seed, and in the regular and perfectmanner in which the cotton is taken by the
brush-rollers when drawn from the seed; and,
thirdly, in the perfect manner in which it is
freed from motes and other impurities by the
blast from the brush-rollers, thus performing
the operations of ginning and cleaning by the
same machine at one and the same time.
Having thus fully described my machine,
whatI claim therein as new, and desire to se-
cure by Letters Patent, is-
1. The method of feeding the cotton -bolls
to the rollers b by means of a blast issuing from
a. slotted or perforated tube or its equivalent,
substantially as herein set forth.
2. I do not claim creating a blast of air to
issue from the periphery of the brush-cylin-
ders by means of Wings within them by their
own velocity, but I claim the arrangement of
the two cylindrical brushes d, in combination
with the rollers b,when the former are so con-
structed that a blast from an independent
source may be forced through slots or perfora-
tions in their peripheries, substantially as and
for the purposes set forth.
3. The copmb e, in combination with the blast-
pipe z for gathering-the lint off the upper
brush-roller and discharging it into its recep-
tacle in the manner set forth.
In testimony whereof I have hereunto set
my hand, before two subscribing witnesses,
this 26th day of March, A. D. 1859.
