Improvements relating to Machinery or Apparatus for Removing
Fibre from Cotton Seed.
I, RICHARD SILCOCK, of Thornton Hall, Poulton-le-Fylde, in the County of
Lancaster, Seed Crusher and Manure Manufacturer, do hereby declare the nature
of this invention to be as follows:-
This invention has reference to improvements relating to machinery or apparatus
for removing fibre from cotton seed. In the class of machinery or apparatus to
which my invention more particularly relates emery or corundum surfaced dises are
arranged at intervals from each other on a common shaft the said discs being
rotated at a
high speed within a box or casing the fibre on the cotton seed being
removed by being rubbed or ground off by contact with the revolving discs.
Various methods have been adopted for holding up or pressing the cotton seed
against the revolving discs but in all such arrangements of apparatus heretofore
known to me it is found that whilst the fibre gets rubbed off around the body part of.
the seed small tufts of the fibre remain on each end of the seed. Now according to
my invention instead of leaving the sides of the discs plain or flat as has heretofore
been the practice I form grooves or channels in the sides of the said discs. The
outer or larger diameter of grooves I prefer to be concentric with and the inner
grooves slightly eccentric to the axis of the disc. The said grooves may be of
various forins in cross section but preferably the outer side of the outer groove is
made parallel with the axis of the disc whilst the inner side of the said groove
gradually slopes up inwardly. Other grooves may also be in the form of rectangular
grooves (oblong in cross section) having two square sides facing each other. Or
the grooves may be semi-circular or otherwise curved in cross section. The object
of the said grooves is that the seed in contact with the sides of the revolving discs
may in addition to being rolled or spun lengthwise against the flat or plain portion
of the discs be caused to spin end wise against the sides or edges of the grooves so.
that the small tufts of fibre hereinbefore referred to may be rubbed off.

Improvements relating to Machinery or Apparatus for Removing
Fibre from Cotton Seed.
1, RICHARD SILCOCK, of Thornton Hall, Poulton-le-Fylde, in the County of
Lancaster, Seed Crusher and Manure Manufacturer, 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 improvements relating to machinery or apparatus.
for removing fibre from cotton seed. In the class of machinery or apparatus to.

page_text: which my invention more particularly relates emery or corundum surfaced dises are
arranged at intervals from each other on a common shaft the said discs being rotated
at a high speed within a box or casing the fibre on the cotton seed being removed
by being rubbed or ground off by contact with the revolving discs. Various methods
have been adopted for holding up or pressing the cotton seed against the revolving
discs but in all such arrangements of apparatus heretofore known to me it is found
that whilst the fibre gets rubbed off around the body part of the seed small tufts of
the fibre remain on each end of the seed. Now according to my invention instead
of leaving the sides of the discs plain or flat as has beretofore been the practice
I form grooves or channels in the sides of the said discs. The outer or larger
diameter of grooves I prefer to be concentric with and the inner grooves slightly
eccentric to the axis of the disc. The said grooves may be of various forms in
cross section but preferably the outer side of the outer groove is made parallel with
the axis of the disc whilst the inner side of the said groove gradually slopes up
inwardly. Other grooves may also be in the form of rectangular grooves (oblong
in cross section) having two square sides facing each other. Or the grooves may
be semi-circular or otherwise curved in cross section. The object of the said
grooves is that the seed in contact with the sides of the revolving discs may in
addition to being rolled or spun lengthwise against the flat or plain portion of the
discs be caused to spin endwise against the sides or edges of the grooves so that the
small tufts of fibre herein before referred to may be rubbed off.
In the accompanying drawings
Fig. 1 is a side view and Fig. 2 a cross section of a disc of the kind hereinabove
referred to in which the grooves a a are eccentric and the groove b concentric
to the axis of the disc.
Figs. 3, 4, and 5 illustrate in section-drawn to a larger scale-the shapes of
some of the grooves I preferably employ Fig. 3 showing that in which the outer
side c of the groove is made parallel with the axis of the disc the inner side d
gradually sloping up inwardly that is to say towards the centre of the said disc.
Fig. 4 shows a rectangular groove with inside rounded corners and Fig. 5 a groove
having a rounded bottom and curved sides.
Fig. 6 shows a modification of the disposition of the grooves on the side of the
disc the grooves e e being curved tangentially.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
In machinery or apparatus for removing fibre from cotton seed the use or
employment of discs having grooves on the sides thereof substantially as hercin-
above described and shown in the drawings.
