or upper portion of the seedbox, while the
other one directly opens into the outlet-pipe
17, which carries off the sand, leaf-trash, and
other objectionable matter that may have been
5 separated from the cotton - seed during the
traverse of the mass containing the latter along
the screen or sieve 14.
The air - blast traveling along the pipe 8
toward the cleaning mechanism carries with
1o it the mass containing the seed, &c., and de-
livers the mass against the upper end of the
screen or sieve 14, such mass being presented
in a proper condition to the screen by a
spreader, as 18, which, it will be perceived, is
15 situated within what might be considered the
seed-chamber of the casing 13, the other cham-
ber being conveniently considered as the dust-
chamber. The spreader 18 consists of an im-
perforate ribbed plate mounted for oscilla-
20 tion at about the junction of the blast-pipe 8
and the upper side of the casing 13 and having
a weighted arm 19, which rests against a pin 20,
placed in one of a series of perforations ex-
tending in a curved direction along the fixed
25 segment 21. In this way the space separating
the lip of the spreader 18 and the screen 14 can
be adjusted to suit different conditions, while at
the same time the spreader is adapted for yield-
ing movement, so that it can recede slightly
30 in case of obstruction in the space mentioned,
whereby the proper action of the machine will
not be affected. Thespreader 18 being imper-
forate, there is no possibility of dust sifting
through the same and into the seed-chamber
35 of the casing at the entering end of the latter.
Initially, therefore, the blast of air and the
mass of material strike against the upper por-
tion of the screen or sieve 14, the air of course
directing the mass against said screen and be-
40 ing of sufficient intensity to initially drive
through the mass dust, sand, and the like
which may be in such mass. At the same
time the blast causes the mass to traverse the
screen. In other words, it gives it a feeding
45 or advancing motion, such motion, of course,
being assisted by gravity, so that the mass
will pass in contact with the screen or sieve,
the air being effective for expelling from the
mass practically all foreign matter that may
5o not have been separated therefrom upon the
initial entrance of the mass into the casing 13
during the contact of such mass with the
screen.
I provide means for securing the positive
55 adherence of the mass to the screen or sieve
14 during its travel therealong. Upon the
inside of the casing 13 and in the seed-cham-
ber thereof I mount the plates 22, which are
angularly disposed with respect to the inter-
6o mediate portion of the screen or sieve 14, and
which plates are normally fixed. These plates
serve to hold the mass against the screen 14
after such mass leaves the spreader 18, so as
to facilitate the separation of the foreign mat-
65 ter therefrom.To suit different conditions, the plates 22
are adjustable, and the adjusting means in
each case is denoted in a general way by 23
and is of a familiar form, consisting of a seg-
ment having means for holding the arms upon 70
the two oscillatory plates in desired positions.
The screen 14 is of arcuate form, as pre-
viously stated, whereby the lower terminal
portion thereof presents, in effect, a pocket
in which the cotton-seed prior to its entrance 75
into the box 4 can momentarily lodge to per-
mit any foreign matter that may not have
been separated therefrom to sift through the
screen and pass into the dust-outlet tube or
pipe 17. This retardation of the seed is of 8o
very brief duration, but is sufficient in prac-
tice to remove all particles of objectionable
matter from the seed before the latter enters
the box 15.
The discharge -opening of the box 15 is 85
shown as provided with two doors, the lower
edges of which close automatically against
each other by means of weighted levers, as
25, connected by means of segmental rods or
links, as 26, with the respective doors. The 90
weights carried by the two levers are of
course adjustable in order to regulate the effi-
ciency thereof, or the same result can be ob-
tained by adjusting the fulcrums of the le-
vers, which are shown as secured by means of 95
an adjustable connection between said levers
and their cooperating rods or links 26.
The seed of course drops from the sieve 14
into the upper side of the box 15, onto the nor-
mally closed doors 24, and when the weight 100
of the seed in the box is sufficient to overcome
the weights of the two levers the seed auto-
matically forces open the two doors or flaps
25 to fall into a suitable receptacle, following
which the doors are automatically closed 105
through the intervention of said weighted
levers.
As previously indicated, I have shown one
simple organization involving my improve-
ments; but I do not wish to limit myself to 11a
the disclosure thus made, for many variations
as to several features of the invention may be
adopted within the scope of my claims.
Having thus described my invention, what
I claim as new, and desire to secure by Letters 115
Patent, is-
1. In an apparatus of the class described, the
combination of an arcuate casing, a seedbox
connected with the casing, automatic means
for closing the delivery end of said seedbox, 120
an arcuate screen in the casing, separating the
same into dust and seed chambers, the lower
end of the seed-chamber opening directly into
the upper end of the seedbox, an air-blast pipe
for delivering air and a mass containing cotton- 125
seed into theupper open end of said casing and
against the screen, an adjustably -supported
spreader located at the entering end of the
casing and serving to spread the material on
its entrance thereinto, and a plurality of angu- 130
