Improvements in Apparatus to be Employed in the Cleaning of
Cotton Seeds.
We, WILLIAM ARTHUR TATTERSALL, of 8 York Place, Cleckheaton, in the
County of York, Clerk, and WILLIAM EDWARD PEARSON of 39 Brook Street,
Cleckheaton aforesaid, Mechanic, do hereby declare the nature of this invention
to be as follows:--
This invention relates to improvements in apparatus to be employed in the
cleaning of cotton seeds, the object being to remove all the adhering cotton or
floss from the seeds preparatory to the latter being crushed for the extraction of
the oil therefrom in the manufacture of oil cake for cattle. The improvements
comprise a hopper for the reception of the seed to be cleaned, the seeds pass from
the bottom of the hopper into a concave tapered dish, the latter being perforated
from the outside so as to leave projecting burr edges in the interior, which serve as
a holding surface for the seeds whilst the latter are acted upon by a taper roller
clothed with card teeth, the action being that the revolution of the card covered
roller serves to comb or card off the cotton from the seeds, the roughened interior
surface of the dish preventing too much freedom in the movement of the seeds.
The dish and taper roller are set at a slight angle or incline, so that the seeds
gradually work towards the lower and discharge end.
The top of the dish is covered with a detachable lid, which can
cleaning the interior or the roller, and a fan may be employed to
or floss from the dish as the seeds are cleaned.

We WILLIAM ARTHUR TATTERSALL of 8 York Place, Cleckheaton in the
County of York, Clerk, and WILLIAM EDWARD PEARSON of 39 Brook Street,
Cleckheaton, aforesaid, Mechanic, 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 :-

page_text: The dish and taper roller are set at a slight angle or incline, so that the seeds
gradually work towards the discharge end.
The top of the dish is covered with a detachable lid; which can be removed for
cleaning the interior or the roller, and a fan may be employed to blow the cotton
or floss from the dish as the seeds are cleaned.
Such being the nature and object of our said invention the following is a
complete description of same, reference being had to the accompanying drawings in
which-
Fig. 1 is a longitudinal sectional elevation of our improved apparatus for purpose
aforesaid.
Fig. 2 is plan view of Fig. 1 with the detachable cover removed.
Fig. 3 is end elevation of apparatus in which two cylinders are employed.
Fig. 4 is a cross section of Fig. 3.
Figs. 5 and 6 are details.
At 1 is a hopper through which the seed is fed to the concave taper dish 2 said
dish being made from strips of sheet metal perforated from the outside so as to
leave burr or rough surfaces of metal around each perforation on the inside of the
dish 2, the roughed surfaces serve as clearing surfaces and also prevent the seed
being carried round by the (preferably) tapered and card covered roller 4, or from
moving too rapidly towards the discharge end of the dish 2, the said strips of sheet
perforated metal we arrange and secure at an angle or inclined as shewn by Fig. 6
so that the action of the card on the roller and the angled strips together serves to
worm or screw the seeds gradually forward in the direction of the discharge end of
the machine. The strips are secured by screws so as to readily admit of removal
of any strips when worn and replacement by new ones if desirable. At 6 is a
detachable perforated cover over the said roller 4 which is mounted on the shaft 7
driven by pulley; 8-9 is the framework. The cotton and floss is drawn through
the perforations in the cover 6 or through the end of the apparatus by means of a
draw fan.
On Sheet 2 we have illustrated a duplicate of above apparatus constructed as
already described, the discharge end of the upper apparatus being connected by a
shoot 10 with the second or lower apparatus so as to submit the seed to a second
cleaning action of the apparatus.
The card clothing is wrapped spirally on the roller so as to work the seeds
towards the discharge end of the apparatus, and the axis 7 of the roller 4 may be
in a horizontal line or at a slight angle sloping towards the discharge end.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. In apparatus for purpose aforesaid the general construction, arrangement
and combination of parts as herein fully described and illustrated by drawings
annexed.
2. In apparatus for purpose aforesaid a revolving and (preferably) tapered card
covered roller combined with a conical perforated or roughened dish as described
and illustrated.
Dated this 20th day of June 1894.
