below the usual seed-board, so that the seed
discharged by the gin will fall into the open-
ing at the top of the hopper and pass thence
to the chute 3, which diverges from the bot-
5 tom of the hopper at an inclination as great
as possible and in the direction of the air-blast
from the exhaust of the fan. While the seed-
chute 3 is thus inclined, it retains, however,
sufficient fall to allow the cotton-seed to slide
io freely down to the blast-flue 4 by gravity.
It will be observed that the lower end or
outlet of the seed-chute 3 connects with the
blast-flue 4 at such an angle as to prevent the
air current or blast from turning up into said
15 chute.
The blast-flue 4 has a cross-sectional area
not less than that of the fan-exhaust and is
extended parallel with and below the gin-
stand, preferably under the floor 9, which will
20 then be provided with openings for passage
of the seed-chutes. One end of the blast-
flue 4 is connected with the exhaust of the
seed-cotton-elevator fan 5 or any other suit-
able fan or blower, and the other end of said
25 blast-flue is to be extended to the place of de-
livery for the cotton-seed.
It is highly important that the area of the
fan-exhaust should be maintained through-
out the length of the blast-flue 4 in order to
30 preserve the suction efficiency of said fan in
connection with the operation of the seed-
cotton elevator. For this reason the blast-
flue 4 is made single or undivided throughout
its entire length, with no restrictions or ob-
35 structions at any point and absolutely valve-
less. It is also very important that the air-
current throug]r the blast-flue 4 should be
prevented from rushing into the several seed-
chutes and thereby obstructing the free dis-
40 charge of the cotton-seed. In order to ac-
complish this result without the employment
of valves or gates that would reducethe cross-
sectional area of the passages for the blast
and the seed, I provide for diverting the air
45 blast or current downward and away from or
beyond the seed-chute outlet in such manner
as to effect a suction that will immediately
draw the seed into the air-blast in the direc-
tion of the air-blast movement and at the
50 same time prevent any considerable entrance
of air into the seed-chute. The means by
which I accomplish these important results
consists in arching or curving the top of the
air-blast flue 4 longitudinally at suitable in-
55 tervals, each arch or curve 10 being located
immediately in rear of the point of connec-
tion between a seed-chute and the blast-flue.
The curve or arch 10 directs the air-current
downward at the point or farther extremity
6o 11 of each arch and diverts it away from the
chute-outlet or flue-opening and beyond the
point 12 at the forward side of the chute-out-
let. Bythus diverting the air-blast from the
outlet of the forward-inclined seed-chute a
65 suction is produced in said chute in such man-
ner as to draw the cotton-seed forcibly into
the air-blast, and by reason of the seed-chutebeing so inclined as to discharge the seed in
the direction that the air-blast is moving it
is obvious that the seed will be freely pro- 70
pelled through the blast-flue without any pos-
sibility of clogging.
It will be seen that by my invention the
cotton-seed will be at once carried from the
gins or linters into the blast and thence con- 75
veyed by the air-blast to any point desired
without any obstruction or back pressure of
the fan-exhaust or any interference with the
proper working of the fan-suction in operat-
ing the cotton - elevating mechanism. The 80
invention may be readily utilized in connec-
tion with a single gin or linter or with a bat-
tery of gins or linters, as may be desired, the
operation being the same in either case.
My invention renders it possible to entirely 85
dispense with the screw conveyer or belt car-
rier and the pulleys, belting, and driving
power necessary for running these, thereby
greatly reducing expenses and entirely avoid-
ing the usual danger of closing the seed-pas- 90
sages, and by also dispensing'with valves or
gates in the air-blast flue a proper cross-sec-
tional area of said flue is maintained in cor-
respondence with the area of the fan-ex-
haust, and the efficiency of the fan is there- 95
by greatly promoted in furnishing a free and
uninterrupted suction for the seed-cotton ele-
vator, whereby the operation of ginning is
rendered more perfect and satisfactory.
Although the location of the blast-flue 4 1oo
under the floor 9, as shown, is generally most
convenient, it will be obvious that it can be
placed above the floor, if desired. The seed-
hopper 2, seed-chute 3, and blast-flue 4 can
be made of wood, sheet-iron, or any suitable o105
material, *wood being usually preferable.
The seed-chute and the blast-flue may be
made either square or circular in cross-sec-
tion and of any size desired, but a rectangu-
lar cross-section of these parts is preferable. Iio
While the drawing shows the air-blast as
coming from the left, it will be obvious that
the fan could be attached to the other end of
the blast-flue; but in that event the seed-
chutes 3 would be reversed, so as to slant to 'I5
the left and discharge the seed in the same
direction with the current or air-blast.
What I claim as my invention is-
1. In a cotton-seed-conveyer system, the
combination with a gin or linter, a fan, a 120
seed-hopper to receive the separated seed
from the gin, and a forward-inclined and
valveless seed-chute leading from said hop-
per, of an unobstructed and valveless air-
blast flue leading from the fan and connect- 125
ing with the said seed-chute to receive seed
therefrom, the said air-blast flue having its
top longitudinally arched immediately in
rear of the point where it connects with the
seed-chute and having throughout its length 130
a cross-sectional area that is nowhere less
than that of the discharge-opening from the
fan, substantially as shown and described.
2. In a cotton-seed-conveyer system, the
