HENRY W. GRABER, OF DALLAS, TEXAS.
COTTON-SEED CONVEYER.
SPECIFICATION forming part of Letters Patent No. 603,185, dated April 26, 1898.
Application filed August 19, 1897. Serial No. 648,813, (No model.)To all whom it may concern:
Be it known that I, HENRY W. GRABER, a
citizen of the United States, residing at pal-
las, in the county of Dallas and State of Texas,
5 have invented new and useful Improvements
in Cotton-Seed-Conveyer Systems, of which
the following is a specification.
It is the object of this invention to improve
the cotton-seed-conveyer system described
io and claimed in Letters Patent No. 584,634,
granted to me June 15, 1897, wherein provi-
sion was made for the removal of cotton-seed
from gins or linters by the exclusive and un-
impeded action of an air-blast through the
15 exhaust-flue of the fan that is ordinarily em-
ployed in connection with the usual elevator
for conducting cotton into the gin-feeders.
Prior to the invention described in my said
former patent it had been proposed to remove
2o cotton-seed from a gin plant by means of an
air - blast mechanism designed to blow the
seed through a horizontal flue having its top
connected with seed-chutes leading from the
gins, and in order to prevent the air-blast
25 from passing up into the chutes it has been
customary to provide gates or valves attached
to the top of the flue by hinges or otherwise,
so that when in operation the valves will be
raised by the blast of air to an angle sufficient
30 to prevent the air-current from entering a
seed-chute. This plan has been shown to be
very objectionable in practice, because it ob-
structs a free and full operation of the air-
blast, and as it is practicable to only partially
35 raise these gates or valves in order that room
may be afforded for the seed to pass over them
into the flue they unavoidably cause an ob-
struction to the free flow of air through the
flue, besides greatly diminishing the cross-
40 sectional area of the exhaust-flue, which pro-
portionately diminishes the capacity of the
fan in supplying the seed-cotton to the gins,
thereby deranging the entire working of the
gin plant and interfering with the high per-
45 fection now required in the handling of seed-
cotton and removal of cotton-seed.
By the invention embraced in my said for-
mer patent there was provided a valveless
seed-conveying flue or pipe having its top
5o arched or curved longitudinally at suitable
intervals, and each curve or arch was located
immediately in rear of the point of connec-tion between a seed-chute and the said seed-
conveyer flue in such manner as to divert the
air-current away from the outlet of the seed- 55
chute, and thus cause a suction in said chute
to draw the cotton-seed forcibly into the seed-
conveyer flue.
My present invention is designed to im-
prove the valveless and longitudinally-arched 6o
seed-conveyer flue to more effectually obviate
obstruction and back pressure, and thereby
greatly facilitate removal of cotton-seed from
the seed hoppers and chutes and incidentally
increase the economy, capacity, and efficiency 65
of the gin plant.
To these ends and for the purpose of avoid-
ing various difficulties incident to a thorough
removal of cotton-seed from gins or linters
by means usually employed my invention con- 70
sists in features of construction and novel
combinations of parts in an apparatus for re-
moving cotton-seed from gins or linters, as
hereinafter more particularly described and
claimed. 75
In the annexed drawings, Figurelisapartly-
sectional elevation illustrating my invention
as applied to a battery of gins or linters.
Figs. 2 and 3 illustrate modifications of the
seed-conveyer blast-flue in longitudinal sec- 8o
tion.
In the drawings the reference-numeral 1
designates a cotton gin or linter. The inven-
tion may be applied to a battery of gins, as
shown, or to one gin only. Beneath each gin 85
or linter is a seed-hopper 2, having its outlet
through a seed-chute 3, leading into a blast
flue or pipe 4, that is connected with the ex-
haust of a fan 5, the suction of which is em-
ployed to draw the seed-cotton into the usual 90
elevator-flue 6 from the seed-cotton house or
from a wagon, as may be most convenient.
This elevator-flue 6 may communicate with
the gins 1 through ducts 7 and feeders 8, as
usual. 95
The gin, the fan, and the elevator-flue may
be of any suitable or ordinary construction
and need not be particularly described, as
they form, of course, no part of my invention,
except in combination with the improved zo
construction of valveless and longitudinally-
arched seed-conveyer flue, through which re-
moval of cotton-seed from the gins or linters
I and seed-hoppers is thoroughly effected by
