MONTIEVILLE M. EDWARDS, OF ABBOTT, TEXAS.
COTTON-SEED SEPARATOR.No. 871,115.
Specification of Letters Patent.
Application filed September 15, 1906. Serial No, 334,731.Patented Nov. 19, 1907.
To all whom it may concern:
Be it known that I, MONTIEVILLE M. ED-
WARDS,a citizen of the United States, resid-
ing at Abbott, in the county of Hill and
5 State of Texas, have invented a new and use-
ful Cotton-Seed Separator, of which the fol-
lowing is a specification.
The invention relates to a cotton seed sepa-
rator.
10 . The object of the present invention is to
improve the construction of sifting machines,
and to provide a simple, inexpensive and ef-
ficient machine adapted for sifting and sepa-
rating cotton seed to enable the large and
15 small seed to be sold or otherwise disposed of
separately, whereby the value of the seed is
greatly enhanced.
A further object of the invention is to pro-
vide a cotton seed sifting machine, adapted
20 to be operated by the wind, and capable of
being readily moved from one place to an-
other, so as to be operated in doors by hand
or other power, when the weather is not suit-
able for operating the machine out doors.
25 With these and other objects in view, the
invention consists in the construction and
novel combination of parts hereinafter fully
described, illustrated in the accompanying
drawing, and pointed out in the claims here-
30 to appended; it being understood that vari-
ous changes in the form, proportion, size and
minor details of construction, within the
scope of the claims, may be resorted to with-
out departing from the spirit or sacrificing
35 any of the advantages of the invention.
In the drawing :-Figure 1 is a perspective
view of a cotton seed separator, constructed
in accordance with this invention. Fig. 2 is
a longitudinal sectional view of the same.
40 Fig. 3 is a plan view of the sifter. Fig. 4 is
an end view of the same.
Like numerals of reference designate cor-
responding parts in all the figures of the
drawing.
45 1 designates a vibratory sifter of oblong
form, composed of side and end walls and a
bottom or sieve 2, which is preferably con-
structed of suitable sheet metal, and which
is provided. at opposite sides of the median
50 line with.transversely disposed parallel open-
ings 3. The openings 3, which are oblong,
are of a size to permit the small cotton seed to
pass through the sieve, which is adapted to
retain the large cotton seed within the sifter.
55 These narrow slots or openings 3 extend sub-stantially across the side portions of the
sieve, but terminate short of the median line
and the side walls of the sieve, and they form
intervening transverse slats 2 and longitu-
dinally disposed central and side connecting 60
portions 3"1 and 4a, which have their upper
f aces arranged in the same plane to enable
the sifter to present a smooth upper face to
the material, so as not to interfere with the
free passage of the same over the sieve. The 65
sides and end wall may be constructed of any
suitable material, and the sifter is provided
at its rear end with an end gate 4, connected
at the top by hinges 5 with a transverse end
bar or section 6 and provided at its lower 70
edge with a suitable catch or latch 7, having a
spring actuated bolt for engaging a keeper 8
of a transverse bottom bar or piece 9, whereby
the end gate is locked in its closed position.
When the end gate is unlatched, it is auto- 75
matically opened by means of a coiled spring
10, arranged on the exterior of the sifter and
connected with the end gate and with the up-
per transverse bar or section 6.1 he coiled
spring 10 is placed under tension by closing 80
the end gate, and it automatically s wings the
latter upwardly when the saie is free to
move. The gate is opened to enable the
sifted seed either to run out or to be shaken
out by the vibration of the sifter. 85
The sifter is suspended within a frame 11
by means of front side links 12 and a cen-
trally arranged rear link 13, and it is vibrated
by a crank shaft 14. The frame 11 is pro-
vided with top and bottom siole bars 15 and 90
16 and it has intermediate and end posts or
uprights 17, 18, and 19, which are secured to
the side bars, and which are connected by
suitable cross bars or pieces. The interme-
diate posts or uprights 17 and the end posts 95
or uprights 19 are extended above the top
side bars 15 to form supports for the osci 1-
latory links 12 and 13. - The links 12 prefer-
ably consist of leather straps, provided with
upper and lower snap hooks 20 and 21, which 100
are linked into suitable eyes of the posts or
uprights 17 and the sides of the sifter. The
end posts or uprights 19 are connected at
their upper terminals by a top transverse
bar 22, provided with a central slot 23, in 105
which is arranged a plate or member 24.
The link 13, which is preferably constructed
of metal, is provided at- its ends with eyes,
which are linked into an eye 25 of the plate
or member 24 and an eye 26 of the rear end 110
