MARGARITO CABRERA, OF SAN ANTONIO, TEXAS.
COTTON-CLEANER.Specification of Letters Patent.
Patented May 6, 1919.
Application filed July 7, 1916. Serial No. 108,011.
To all whom it may concern:
Be it known that I, MARGARiTO CABRERA,
a citizen of the Republic of. Mexico, residing
at San Antonio, in the county of Bexar and
5 State of Texas, have invented certain new
and useful Improvements in Cotton-Clean-
ers; and I do hereby declare the following to
be a full, clear, and exact description of the
invention, such as will enable others skilled
10 in the art to which it appertains to make
and use the same.
This invention relates to cotton cleaners,
and the primary object of the invention is
to provide a cotton cleaner wherein the cot-
15 ton is drawn into and through the cleaner by
air suction, which cleaner casing is provided
with a pair of hinged sections, so that the in-
terior of the cleaner may be easily and
quickly released, and also so that in case the
20 cotton within the cleaner catches fire, the
sides may be opened, allowing the rotor of
the cleaner to throw the dirty cotton out of
the cleaner, and owing to the fact that cotton
is drawn into and through the cleaner by air
25 suction, the feeding of the cotton into the
cleaner will be arrested because the opening
of the sides of the casing will break the di-
rect line of air suction.
Another object of this invention is to pro-
30 vide a cotton cleaner as specified which in-
cludes a plurality of rotary members having
radially extending webs carried thereby
which carry the cotton over foraminous
screens through which the foreign matter is
35 forced, which structure is arranged for thor-
oughly cleaning the cotton fiber without
twisting the same and further to provide agi-
tators at the end of the cleaner which will
fluff or loosen the cotton prior to and after
40 passage through the cleaner.
With the foregoing and other objects in
view this invention consists in such novel
features of construction, combination and
arrangement of parts as will be hereinafter
45 more fully described, illustrated in the ac-
companying drawings and claimed.
In describing the invention in detail ref-
erence will be had to the accompanying
drawings wherein like characters designate
50 like and corresponding parts throughout the
several views, and in which
Figure 1 is a side elevation of the im-
proved cleaner having the parts thereof
broken away,
55 Fig. 2 is a horizontal section through the
improved cleaner,Fig. 3 is an end view of the cleaner,
Fig. 4 is a vertical section through the
cleaner,
Fig. 5 is a detail perspective view of one 60
of the rotary members of the cleaner, and
Fig. 6 is a fragmentary section through
the cleaner illustrating one of the agitating
or fluffing members.
Referring more particularly to the draw- 65
ings, 1 designates the casing of the cotton
cleaner, which is substantially heart shaped.
A flue 2 is carried by the top of the casing 1
and it has valves 3 and 4 positioned therein
as clearly shown in Fig. 1 of the drawings. 70
Any suitable type of air suction device may
be connected to one end of the flue 2 for
drawing cotton inwardly into the cleaner
through the. end 5 and outwardly out of the
cleaner through the end 6. The valves 3 75
and 4 are provided for regulating or cut-
ting off the air suction.
The sections 7 and 8 of the casing 1 are
hingedly connected as shown at 9 to the flue
2, so that they may be moved outwardly for 80
permitting access to the interior of the
cleaner if it is so desired.
A plurality of supporting braces 10 are
positioned at spaced distances interiorly of
the casing 1 and they support the lower sec- 85
tions of the foraminous screens 11. The sec-
tions 7 and 8 have portions 12 of screen
attached thereto the lower edges of which
meet with the edges of the portion 11 as
clearly shown in Fig. 4 of the drawings for 90
forming a continuous foraminous lining
within the cleaner over which the cotton is
passed through the rotary action of the
rotors 14 and 15. The rotors 14 and 15 are
mounted upon shafts 16 and 17 respectively, 95
which shafts are rectangular intermediate
their ends, upon which rectangular portions
the rotors are mounted. The shafts 16 and
17 project outwardly out of the ends of the
casing and they are supported by suitable 100
bearings or pillow blocks 18. The shaft 16
has a driving pulley 19 mounted upon one
end of the same and a gear 20 mounted, upon
the other end. The gear 20 meshes with a
'gear 21 which is mounted upon the shaft 105
17 whereby the shaft 17 will be rotated by
the shaft 16 in an opposite direction to the
rotation of the shaft 16 and the rotor car-
ried thereby. The rotors 14 and 15 com-
prise cores or cylindrical hubs 23 which have 110
a plurality of ribs or radiating blades 24
attached thereto. The blades 24 are straight1,303,026.
