is fitted to tie outer side of tie fan to close
in the spaces between the blades thereof and
provide a break for the air as it rushes into
the fan-casing through the inlet 6 thereof, and
thereby insure an easy discharge of the air
through the discharge-opening 8 and prevent
undue friction within the fan-casing by hold-
ing the air between the blades of the fan until
discharged out through the opening 8.
In the operation of the apparatus the rapid
revolution of the rotary fan creates a suction
within the pipe 1 and draws the cotton from a
point of supply through such pipe into the
separating-box 2. As the cotton is drawn
within the separating-box 2 the same impacts
itself against the conical separating-screen 17,
while the air passes through said screen and
into and out of the fan-casing, and at this
point it will be noted that the disk 1S at the
apex of the separating-screen prevents any of
the cotton from lodging on said apex of the
screen and clinging thereto. The cotton which
impacts itself on the separating-screen 17 is
thrown off of said screen by centrifugal force
against the sides of the separating-box 2, and
falls of its own weight through the discharge-
chute 3 and into the distributor 4, which then
distributes the cotton to the several gins em-
ployed in connection with the apparatus. As
already stated, the air which passes through
the separating-screen into the fan-casing is
caught by the blades of the fan and held
within the fan by the shield-plate 19 until it
reaches the point where it follows the curva-
ture of the air-deflecting portion 9 of the shell
of the fan-casing, and by following the lines
of said deflecting portion 9 of the fan-casing
the air meets the least possible resistance to
the free discharge thereof out of the dis-
charge-opening S, and therefore creates no
material back pressure on the fan, as will be
readily understood by those skilled in the art.
Changes in the form, proportion, and the
minor details of construction may be resorted
to without departing from the principle or
sacrificing any of the advantages of this in-
vention.
Having thus described the invention, what
is claimed, and desired to be secured by Let-
ters Patent, is-
1. In a cotton elevator and distributer, the
combination with a suction supply-pipe, and
a distributer; of a separating-box connected
with said supply-pipe and said distributer,
and provided in one side with an air-discharge
opening, a suitable suction-fan connection
with said air-discharge opening, a rotary sepa-
rating-screen arranged wholly within the sep-arating-box at one side of said air-discharge
opening with its axis of rotation in lineal 60
alinement with the portion of the supply-pipe
opening into the separating-box, whereby the
screen will be disposed in a position for re-
lieving itself of the cotton by centrifugal force,
and means for rotating said screen, substan- 65
tially as described.
2. In a cotton-handling apparatus, a sepa-
rating-box having suitable air-suction con-
nections therewith and provided at the bot-
tom with a cotton-discharge opening, a rotary 70
conical separating-screen arranged-within the
separating-box with its axis of rotation dis-
posed in line with the cotton-inlet, and means
for rotating said screen, substantially as de-
scribed. 75
3. In a cotton elevator and distributer, the
combination with a suction supply-pipe, and
a distributer; of a separating-box connected
with the supply-pipe and said distributer and
provided in one side with a fan inlet-opening, 80
a fan-casing mounted at one side of said box
over said opening, a suction-fan rotating in
said casing with its shaft in line with the sup-
ply-pipe connection with the separating-box,
a rotary separating-screen mounted on the 85
fan-shaft so as to have its axis of rotation dis-
posed in line with the cotton-inlet and ar-
ranged to work wholly within the separating-
box at the side of the fan inlet-opening op-
posite the location of the fan, and means for 90
rotating said screen, substantially as set forth.
4. In a cotton elevator and distributer, the
combination with a suction supply-pipe and
a distributer; of a separating-box connected
with said pipe and said distributer and pro- 95
vided in one side with a fan inlet-opening, a
fan-casing mounted at one side of said box
over said inlet-opening, a horizontal fan-shaft
arranged centrally within the fan-casing and
projecting through said inlet - opening into ioc
said separating-box, a rotary fan mounted on
the shaft within the fan-casing and provided
at its outer side with a circular shield-plate,
a conical separating-screen mounted on the
inner projecting end of the fan-shaft and io
within the separating-box, and a concaved
shield-disk fitted on the inner extremity of
the fan-shaft at the apex of said screen, sub-
stantially as set forth.
In testimony that I claim the foregoing as I Ic
my own I have hereto affixed my signature in
the presence of two witnesses.
