GALVESTON, TEXAS.
COTTON-CLEANING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 547,671, dated October 8, 1895.
Application flied June 25,1895. Serial No. 564,030. (No model.)To all whom it m7ay concern:
Be it known that I, STEPHRFM D. MURRAY, a
citizen of the United States, residing at Dallas,
in the county of Dallas and State of Texas,
5 have invented new and useful Improvements
in Cotton-Cleaning Apparatus, of which the
following is a specification.
This invention relates to that class of seed-
cotton cleaners comprising a stationary foram-
co inous case or drum having an inlet-opening
in the upper side of its small end, a rotary
shaft extending centrally through the case or
drum and having a plurality of spirally-ar-
ranged beater-arms, and an air-forcing fan
r5 arranged at the large end of the foraminous
case and having a discharge-pipe for convey-
ing the cotton to the point where it is to be
deposited or discharged-as, for instance, into
gins or gin-feeders.
20 In the practical use of the former cleaners
of the character briefly referred to the cotton
is delivered to the inlet-opening in the small
end of the foraminous case or drum through
the medium of cotton-elevating mechanism,
25 and the beater-arms on the rotary shaft agi-
tate and move the cotton along the inner sur-
face of the case or drum to and through the
large end thereof, where the fan acts to drive
the cotton through the discharge-pipe to the
30 gins, the construction and operation being
such that dirt, dust, and trash are separated
from the cotton and driven through the open-
ings or perforations in the case or drum into
the cleaner-room in which the apparatus is
35 located.
In the ordinary use of cotton-cleaners as
heretofore constructed a special cleaner-room
is provided for the cleaner and a cotton con-
veyer or elevator is arranged in operative
40 connection with the cleaner to furnish a sup-
ply of cotton thereto. The great quantity of
dirt and dust discharged into the cleaner-
room is objectionable for many reasons, par-
ticularly as it presents a very bad condition
45 for the belts employed to transmit power to
the working part of the cleaner and to the
cotton conveyer or elevator.
The provision of a conveyer or elevator for
raising and delivering the seed-cotton to the
50 cleaner is a mechanical element which in-creases the cost of the apparatus, and which
it is desirable to dispense with. In many gin-
neries it is necessary to employ a number of
cleaners, located at different points in the
building, and in such cases the objections to
a cleaner-room are largely increased, in that
a separate cleaner-room is employed for each
cotton-cleaner.
The objects of my invention are to avoid
the objections hereinbefore alluded to, and to
provide a novel, simple, and effective cotton-
cleaning apparatus which entirely avoids the
provision of a special cleaner-room, and which
delivers the separated dirt and dust out of
the building through or by means of the blast
of a suction-fan, or in a condensed state by
gravity through a suitable conduit to any
suitable receptacle, from which it can be
carted or transported.
The invention also has for its object to pro-
vide new and improved means whereby the
dirt and dust are effectually separated from
the cotton and prevented from being scattered
about the building.
The invention also has for its object to pro-
vide novel means whereby a suction appara-
tus serves to carry a continuous flow or
stream of cotton from the source of supply
into the cotton-cleaner, while the work of
cleaning the cotton is performed by the ac-
tion of beater-arms, and the dirt and dust are
discharged either by the blast from a suction-
fan or in a condensed state through a suitable
conduit.
The invention also has for its object to pro-
vide means for discharging the cleaned cot-
ton from a drum arranged in a casing in which
a partial vacuum is maintained for the pur-
pose of drawing the cotton into the drum.
The invention also has for its object to pro-
vide novel means whereby a suction appara-
tus is utilized to draw cotton into a cotton-
cleaner. The cotton is cleaned ina partial
vacuum produced by the suction apparatus,
and the dirt and dust and the cotton are de-
livered by gravity from the cleaner.
To accomplish all these objects my inven-
tion involves the features of construction, the
combination or arrangement of parts, and the
principles of operation hereinafter described
