PROVISIONAL SPECIFICATION left by the said Richard Davison at the
Office of the Commissioners of Patents on the 5th April 1876.
RICHARD DAVISON, of Driffield, in the County of York, Secretary to the Driffield

MACHINERY OR APPARATUS TO BE EMPLOYED IN CLEANING COTTON SEED."
The Invention has for its object improvements in machinery or apparatus to be
employed in cleaning cotton seed, and separating therefrom the cotton fibre, dust,
and other extraneous matter before pressing it into cake for cattle food. For
this purpose I employ a series of drums or barrels (preferably three) placed one
above another in or nearly in a horizontal direction. Each of these drums or
barrels is provided with a central shaft or axis, on which are arranged a series of
steel blades set at a small angle thereon. Each drum or barrel at the outlet end
thereof is connected to trunks or passages, which communicate with an ordinary
exhaust fan. The upper drum or barrel is provided at or near one end thereof
with a hopper into which the cotton seed is fed, and at the lower end of each trunk
or passage is a box or receiver in which any sced accidentally drawn away by the
exhaust is received..
The action of the machinery or apparatus is as follows:-The cotton seed to be
cleaned is fed through the hopper into the uppermost drum or barrel where it is
acted upon by the revolving blades, and gradually conducted to the other or outlet
end of the drum or barrel, it thence falls by a shoot into one end of the next drum
or barrel, and in doing so the exhaust acts to draw off the fibre, dust, and other
extraneous matter therefrom, into the trunks or passages communicating with the
fan or exhaust apparatus. The cotton seed in the second drum or barrel is then
treated in a similar manner to that described with respect to the first drum or

page_text: barrel, and so on, until it is discharged from the third or last drum or barrel
completely cleaned.
barrel, and so on, until it is discharged from the third or last drum or barrel
completely cleaned.
The dust, cotton, and other extraneous matter is taken away by the exhaust into

by the said Richard Davison in the Great Seal Patent Office on the 2nd October
1876.

MACHINERY OR APPARATUS TO BE EMPLOYED IN CLEANING COTTON SEED."
The Invention has for its object improvements in machinery or apparatus to be
employed in cleaning cotton seed and separating therefrom the cotton fibre, dust,
and other extraneous matter before pressing it into cake for cattle food. For this
purpose I employ a series of drums or barrels (preferably three) placed one above
another in or nearly in a horizontal direction. Each of these drums or barrels is
provided with a central shaft or axis, on which are arranged a series of steel blades
set at a small angle thereon. Each drum or barrel at the outlet end thereof is
connected to trunks or passages which communicate with an ordinary exhaust
fan. The upper drum or barrel is provided at or near one end thereof with a
hopper, into which the cotton seed is fed; and at the lower end of each trunk or
passage is a box or receiver in which any seed accidentally drawn away by the
exhaust is received. The dust, cotton, and other extraneous matter, is taken away
by the exhaust into a separate place.
And in order that my said Invention may be more clearly understood and
readily carried into effect I will proceed, aided by the accompanying Drawings,
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section on the line A, B, of Figure 3; Figure 2 is a front
elevation; and Figure 3 is a plan of machinery or apparatus to be employed in
cleaning cotton seed constructed according to my Invention; and Figure 4 is a
longitudinal section through one of the drums or barrels.
a, b, c, represent three drums or barrels placed in horizontal positions one above
another; each of these drums or barrels is provided with a central shaft or axis d,
on which are arranged a series of steel blades, set at a small angle thereon, and
extending to near the inner peripheries of the drums or barrels. Each of these
shafts or axes & has fixed on one end thereof a drum or pulley d², by which it
receives motion by straps or bands from any suitable motive power. The upper
drum or barrel a is provided at or near one end thereof with a hopper a¹, into
which the cotton seed is fed; and at the other end such drum or barrel is con-
nected with a trunk or passage e, as is also the drum or barrel c. The drum or
barrel is connected at one end to a trunk or passage f, and these trunks or
passages e, f, are both connected with an exhaust fan fixed on the axis g in the
chamber driven by a strap or band passing around the pulley g². The steel
blades of each of the drums or barrels b, c, are set at the contrary angle to those
in the drum or barrel immediately above it, and the drum or barrel a is provided
with a shoot a² to direct the cotton seed from the left hand end thereof into a
passage communicating with the drum or barrel b; and this latter has at its
right hand end a shoot b to direct the cotton seed into a passage c¹ communicating
with the drun or barrel c, which latter is provided with a shoot c² to discharge
the cotton seed therefrom on to a guide or shoot h, whence the cleaned cotton seed
is conducted to any suitable receptable. At the lower end of each trunk or

page_text: passage e, f, is a box or receiver c¹, f, in which any seed accidentally drawn away
by the exhaust is received.
The action of the machinery or apparatus is as follows:-The cotton seed to be
cleaned is fed through the hopper al into the drum or barrel a, where it is acted
upon by the revolving blades d' therein and gradually conducted by the action of
such blades to the other or outlet end of such drum or barrel a; it thence falls by
n shoot a into one end of the drum or barrel b, and in doing so the exhaust acts
to draw off the fibre, dust, and other extraneous matter separated therefrom by the
blades into the trunk or passage e communicating with the fan or exhaust
apparatus. The cotton seed in the drum or barrel is then treated in a similar
manner to that described with respect to the drum or barrel a, whence it is con-
ducted by a shoot b to the drum or barrel c; and after it has been acted upon by
the steel blades in such drum or barrel c it is discharged therefrom by a shoot c²
completely cleaned.
The dust, cotton, and other extraneous matter, is taken away by the exhaust
and discharged by the spout g³ into a separate place.
Having thus described the nature of my said Invention, and the mode in which
I carry the same into effect, I would have it understood that I do not claim the
various parts separately considered, but what I do claim is, the peculiar arrange-
ment and combination of machinery or apparatus to be employed in cleaning cotton
sced, substantially as herein shown and described.
In witness whereof, I, the said Richard Davison, have hereunto set my hand
and scal, this Twenty-ninth day of September in the year of our Lord One
thousand eight hundred and seventy-six.
