PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cleaning Cotton Seeds.
We, EDWARD SHEARDOWN and JOHN CHARLES BARKER of No. 44 High Street
Hull, in the County of Hull, Seed Crushers, do hereby declare the nature of this
invention to be as follows:-
In our Specification No. 18,011 of 1888 we have described means of cleaning
cotton seeds from dirt and fibre by passing them through a series of machines. Our
present invention relates to further apparatus whereby the seeds after being cleared
from dirt and fibre can be still more effectually cleaned and polished. The machine
for this purpose consists of a cylinder or barrel which may be of wood having
fastened on it a number of longitudinal strips of leather or equivalent material the
free edge of each strip overlapping the fixed edge of the strip next behind it. This
barrel is caused to revolve within a casing consisting of segment strips of metal file
cut or otherwise roughened alternating with strips of wire gauze. The seeds are fed
into the annular space between the barrel and the casing at one end of the machine
and travel along this space subject to a rolling and rubbing action which has the
effect of thoroughly cleaning and polishing them. In order to cause the seeds to
travel longitudinally, the machine is inclined downwards from the free end, and the
strips are fixed somewhat helically on the barrel. In order to remove the fibres and
small particles rubbed off the seeds, the machine is placed within a case subject to the
draught of an exhaust fan.

Improvements in Apparatus for Cleaning Cotton Seeds.
We, EDWARD SHEARDOWN, and JOHN CHARLES BARKER, of No. 44 High Street
Hull, in the County of Hull, Seed Crushers, 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 :-
In our specification No. 18011 of 1888 we have described means of cleaning cotton
seeds from dirt and fibre by passing them through a series of machines. Our present
invention relates to further apparatus whereby the seeds after being cleared from diri
and fibre can be still more effectually cleaned and polished. The machine for this
purpose consists of a cylinder or barrel which may be of wood having fastened on it
a number of longitudinal strips of leather or equivalent material, the free edge of
each strip overlapping the fixed edge of the strip next behind it. This barrel is caused
to revolve within a casing consisting of segment strips of metal file cut or otherwise
roughened, alternating with strips of wire gauze. The seeds are fed into the annular
space between the barrel and the casing at one end of the machine and travel along
this space subject to a rolling and rubbing action which has the effect of thoroughly
cleaning and polishing them. In order to cause the seeds to travel longitudinally, the
machine is inclined downwards from the feed end, and the strips are fixed somewhat
helically on the barrel. In order to remove the fibres and small particles rubbed
off the seeds, the machine is placed within a case subject to the draught of an
exhaust fan.
Fig. 1 of the accompanying drawings is a longitudinal section and Fig. 2 is a
transverse section of apparatus according to our invention. A is the barrel having
fixed on it longitudinal strips a of leather or like material, these strips being of such
D

page_text: depth and so inclined to the radius that the free edge of each overlaps the fixed edge
of the next strip behind it, and each being helically inclined to the axis. B is the
cylindrical casing having its circumference made up of sets of segments of metal
internally file cut or otherwise roughened, and alternating with them segments of
wire gauze.
We prefer to roughen the segments on both sides so that when one
side is worn they may be inverted. The casing B has at the one end on its upper
side the feed opening C, and at its other end on its lower side the discharge opening D.
The whole is enclosed within the case E, having from it a passage e governed by a
valve leading to an exhaust fan, and a door e¹ by which the matter deposited in the
case can from time to time be removed. The barrel A is fixed on a shaft F which is
caused to revolve by any convenient, motor. The seeds introduced at C are carried
round by the revolution of the barrel and caused to travel to the outlet D whence
they issue cleaned and polished by the rubbing and rolling action, while the fibres and
small particles rubbed off are drawn by the exhaust through the meshes of the
gauze.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manuer the same is to be performed we declare that what we
claim is :-
Apparatus for cleaning and polishing cotton seeds consisting of a barrel carrying
strips of leather or equivalent material made to revolve within a cylindrical casing the
periphery of which consists of segments of roughened metal alternating with segments
of wire gauze, substantially as described.
