Improvements in Machinery for Cleaning Cotton Seed.
I, JAMES BIBBY, of Bixteth Street, Liverpool, in the County of Lancaster,
Oil-refiner, do hereby declare the nature of this invention to be as follows:-
This invention has reference to machinery for removing the short fibre or lint
which adheres to most cotton seeds after the bulk of cotton has been removed, that
is to say, the seed, in the condition it is imported into this country; and my
invention has for its object to provide certain improvements hereinafter specified,
connected with such machinery.
According to one part of this invention, a special mode of feeding cotton seal
cleaning machinery consisting mainly of a horizontally disposed cylinder and an
inner revolving barrel, having an annular space between them, in which the seed is
operated upon and cleaned in passing from one end to the other (as for instance,
the machine set forth in the Specification of my application for Patent No. 21372
of 1893), is provided. Under the present invention, in order to keep the annular
space between the barrel and the cylinder filled with seed (this being, I find, very
desirable), there is provided in connection with the feeding part or ineans of the
machine, means of forcing under pressure the seeds into such annular space, by
which not only will the tendency of the seed, which ordinarily exists under such
circumstances, not to enter such space, is overcome, but it is forced forward along
such space against same, and at the same time keeping it full of seed. A convenient
and effective forcing means for charging the seeds under pressure into the annular
space consists of a short pitched screw or worm, mounted on the axle of the
rotating barrel, the seed being fed from a hopper into the space between the first
thread or threads of the worin or screw, and then carried on through another or
others and discharged therefrom into the said annular space.
According to another part of this invention, in a cotton seed cleaning machine
of the kind above referred to, wherein emery or analogous material is used as a
lining to the outer cylinder as a means of holding the seed against the rotative
action of the barrel, and also acting upon it, such emery or material is arranged
and held in longitudinal strips on the inner side of metal cylinder, or part of a
cylinder, between division bars of metal forming part of or on said cylinder,
thereby dividing the emery or like lining up into a number of parts, and so
restricting damage or breakage of the lining to the part or parts at which it
commences, and preventing its spread or continuation to other parts. The emery
is held by dovetail formation of the spaces formed between the different division
bars on the cylinder, or part of the cylinder. The emery is applied to the cylinder
in a plastic condition, and then dried.
A convenient construction of the barrel above described, in the case of its
application to a machine as set forth in the Specification of my former application
for Patent above referred to, the cylinder may be conveniently made up of three
parts, an upper semi-cylinder, and a quarter of a cylinder below, the other quarter
being bars through which the removed cotton is discharged.

page_text: I, JAMES BIBBY, of Bixteth Street, Liverpool, in the County of Lancaster,
Oil-refiner, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has reference to machinery for removing the short fibre or lint
which adheres to most cotton seeds after the bulk of cotton has been removed, that
is to say, the seed, in the condition it is imported into this country; and my
invention has for its object to provide certain improvements hereinafter specified,
connected with such machinery.
According to one part of this invention, a special mode of feeding cotton seed
cleaning machinery consisting, mainly, of a horizontally disposed cylinder and an
inner revolving barrel, having an annular space between them, in which the seed is
operated upon and cleaned in passing from one end to the other, (as for instance,
the machine set forth in the Specification of my application for Patent No. 21372
of 1893), is provided. Under the present invention, in order to keep the annular
space between the barrel and the cylinder filled with seed (this being, I find, very
desirable), there is provided in connection with the feeding part or means of the
machine, means of forcing under pressure the seeds into such annular space, by
which, not only will the tendency of the seed, which ordinarily exists under such
circumstances, not to enter such space. be overcome, but it is forced forward along
such space against same, and at the same time keeping it full of seed. A convenient
and effective forcing means for charging the seeds under pressure into the annular
space consists of a short pitched screw or worm, mounted on the axle of the
rotating barrel, the seed being fed from a hopper into the space between the first
thread or threads of the worm or screw, and then carried on through another or
others and discharged therefrom into the said annular space.
According to another part of this invention, in a cotton sred cleaning machine
of the kind above referred to, wherein cmery, or analogous material, is used as a
lining to the outer cylinder as a means of holding the seed against the rotative
action of the barrel, and also acting upon it, such emery or material is arranged
and held in longitudinal strips on the inner side of metal cylinder, or part of a
cylinder, between division bars of metal forming part of or on said cylinder,
thereby dividing the emery, or like lining, up into a number of parts, and so
restricting damage or breakage of the lining to the part or parts at which it
commences, and preventing its spread or continuation to other parts. The emery
is held by dovetail formation of the spaces formed between the different division
bars on the cylinder, or part of the cylinder. The emery is applied to the cylinder
in a plastic condition, and then dried.
As a convenient construction of the barrel above described, in the case of its
application to a machine as set forth in the Specification of my former application
for Patent above referred to, the cylinder may be conveniently made up of three
parts, an upper semi-cylinder, and a quarter of a cylinder below, the other quarter
being bars through which the removed cotton is discharged.
In the drawings illustrating the invention, the nature of which is above described,
Figure 1 is a longitudinal sectional elevation, and Figure 2 is a cross section of n
machine provided with the present improvements.
Referring to these drawings, A designates generally the outer case or cylinder
of the machine, while B is the inner rotating barrel or drum. a is the lining of
the cylinder A, which is of emery, corundum, or the like, and is held in position as
hereafter described. The surface of the barrel B is preferably also of similar
material, and may be made in the manner set forth in the Specification of my said

page_text: former Patent.
is the hopper or shoot down which the seeds to be cleaned are
led into the machine; and is the outlet conduit. e is the screw or worin in the
inlet end of the machine, by which the seed is forced through the annular space
between the outer barrel and the drum, one part being of a true screw form, and
the part being an armed device on the end of the screw e, the arms of which are
inclined. is a similar arined device at the outlet end of the drum, which assists
in discharging the cleaned seed.
ان
It will be seen that the worm or screw e is placed on the shaft of the drum B,
and directly under the feeding or inlet shoot c, and is of less diameter than the
drum B, the outer cylinder A at this end where the screw comes, being diminished
in diameter, so as to be filled or nearly filled by the screw or worm.
In action, the outlet d being placed practically at the top of the outer cylinder A,
the annular space between the cylinder and rotating barrel will be kept full of seed,
this being necessary to obtain efficient results. The seed thus passes through
the machine in an annular stream, and to get the seeds to pass properly through
the machine, and at the desired rate, it is found necessary that they must be forced
into the annular space and through it, and by the arrangement and combination of
the means of forcing described and shewn, the desired artificial feeding of the seeds
into the said annular space, and its propulsion through it against the resistance, is
accomplished.
As regards the construction of the outer cylinder A, this is made up of three
parts, an upper semi-cylindrical half a', a quarter of a cylinder a³, and a third
quarter of a cylinder a³. The parts a' a² are conveniently made of cast iron,
longitudinal ribs at being formed on the interior, which form dovetail channels on
the interior of the casing; and these dovetail channels are filled with emery
corundum or similar abrasive material. By this construction the emery, or the
like, if or when it becomes cracked or broken at any part, the crack or break is
limited to the strip at the point where the said break takes place, viz. in one of the
channels. The formation of the channels also key the emery in position on the
cylinder. The portion a simply consists of bars or grids, the bars of which are
circumferentially disposed, and through which, saws used for removing the removed
fibre are placed and work, as in my former machine described under my aforesaid
Specification.
As in my said former machine, the cleaning of the seeds, that is the removal of
their adhering fibre, is effected by emery or the like in the rotating barrel B, in
conjunction with the emery or like surface of the outer cylinder A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A machine for cleaning cotton seed adapted to have the seed passed in an
annular stream along an annular space through it, and acted upon by an inner
rotating barrel on the inside of said annular stream, and having forcing and pro-
pelling means in connection with said barrel, arranged and operating substantially
as and for the purposes herein set forth.
2. In machinery for cleaning cotton seed, wherein a rotating barrel and an outer
cylinder are employed, the construction of the outer cylinder of an outer casing
having longitudinal ribs on the inner side thereof, forming dovetail channels, said
channels being filled with emery or like abrasive material; substantially as for the
purposes set forth.
3. The cotton seed cleaning machine having its parts arranged, combined, and
adapted to operate, particularly as set forth with reference to and shewn in the
drawings.
