DAVID H. GREESON, OF BOWIE, TEXAS.
Specification of Letters Patent.
Patented Oct. 26, 1909.
Application filed May 31, 1906, Serial No. 319,639. Renewed March 20, 1909. Serial No. 484,802.
To all whom it may concern:
Be it known that I, DAvm H. GamsoN, a
citizen of the United States, residing at
Bowie, in the county of Montague and State
of Texas, have invented a new and useful
Cotton-Seed Conveyer, of which the follow-
ing is a specification.
This invention has relation to cotton seed
conveyers and it consists in the novel con-
struction and arrangement of its parts as
hereinafter shown and described.
The object of the invention is to provide
a means for discharging cotton seed from
one or a battery of cotton gins.
The invention consists primarily of a flue
which is located below the gins and into
which the same discharge. The said flue is
provided with a straight flat bottom and in
its top with valves of special construction
D and arrangement to control the introduction
of seed into the flue and at the same time to
regulate and properly direct a blast of air
that passes through the flue and constitutes
the seed conveying medium, a suitable means
5 being provided for supplying such blast of
In the accompanying drawing, the figure
is a longitudinal sectional view of a flue ap-
plied to the cotton gins.
30 The flue 1 is located below the gins 2, 2,
the discharge from the said gins entering
the top of the said flue at the points 3. The
fan casing 4 is attached to one end of the
flue 1 and is provided with the rotating fan
35 5 which is .adapted to force a blast of air
through the said flue 1. To one side of each
of the openings 3 is.located a valve 5a which
is adapted to slide in an inclined direction
with relation to the straight bottom 6 of the
40 said flue. The lower end of said valve 5a
is at all times farther away from the fan 5
than the upper end thereof. Said valve at
its lower end is rounded as at 7, said rounded
portion extending transversely across the
45 valve and the extreme end of the said valve
terminates in the edge 8 which is in the same
plane as the under surface of the valve. The
said valve 5a is adapted to be adjusted in
order to regulate the blast of air from the
50 fan 5 through the flue 1 and the edge 8 at
the lower end of the valve is so positioned
in order that the blast of air in passing
under the lower end of the valve 5a is
crowded or forced against the straight or
55 flat bottom 6 of the flue 1, the object of this
construction being that the blast when so
treated will not have a tendency to seek an
outlet from the flue 1 by passing up through
the gin 2.
The flow of seed from the gin 2 is regu- 60
lated by the valve 9 which is adapted to be
adjusted in the top and sides of the flue 1 so
that its lower edge may be moved away from
or brought close to the upper face of the
valve 5a. The said valve 9 is also pitched at 65
an incline to the longitudinal axis of the
flue I and its straight bottom 6. It is ob-
vious that the blast of air in passing through
the flue will carry the cotton seed to any de-
sired or determined point or receptacle with 70
which the said flue may be connected. The
said valves 5a, 5a have a tendency to confine
the blast of air against the straight bottom
6 of the flue 1 and thus the seed conveying
means passes through the lower portion of 75
the flue 1 and as the bottom 6 thereof is
straight, no obstruction is offered.
The essential features of the invention re-
side in the combination of the straight bot-
tom of the flue with the peculiar blast con- 80
trolling valve and its relative position to the
Another feature resides in the longitu-
dinally adjustable wind valve 5a in combi-
nation with the longitudinally adjustable 85
seed valve 9 arranged in the specific manner
as shown and described. By such arrange-
ment the valve 9 may be adjusted with re-
lation to the valve 5a so as to permit the seed
to flow into the flue 1 in a fine stream. Also 90
the seed is introduced into the said flue be-
hind the draft and runs down along the
valve 5a in the general inclination of the
blast of air and commingles with the blast at
the lower end of the said valve 5. Thus 95
the seed is given the general direction of the
blast prior to its introduction into the same
and after the quantity of flow of the seed is
regulated the quantity of the blast may be
regulated by adjusting the valve 5a without 100
altering the quantity of flow of the seed.
Having thus described my invention, what
I claim as new and desire to secure by Let-
ters Patent is:-
A pneumatic conveyer comprising a flue 105
having a flat bottom and an opening in its
top, means for forcing a blast of air through
the flue, a chute arranged above the flue,
synclinal sliding valves constituting the bot-
tom of the chute and passing through the. 110
opening in the flue and coperating with
each other in retaining seed, one of the valves
Here’s what’s next.
