page_text: LETTERS PATENT to Charles Henry Robinson, John Fryer, and Abraham
Dyson, all of Oldham, in the County of Lancaster, Mechanics, for the
Invention of "CERTAIN IMPROVEMENTS IN APPARATUS CALLED 'GINS,' FOR
PROVISIONAL SPECIFICATION left by the said Charles Henry Robinson,

We, CHARLES HENRY ROBINSON, JOHN FRYER, and ABRAHAM DYSON, all of
Oldham, in the County of Lancaster, Mechanics, do hereby declare the
nature of the said Invention for "CERTAIN IMPROVEMENTS IN APPARATUS
CALLED 'GINS' FOR CLEANING SEED COTTON." Lo be as follows:-
Our Invention relates to that part of the cotton "gins" called the stripping
roller, and is usually covered with leather and grooved spirally around its
periphery.
The improvements consist in the employment, application, and use of mill-
board, brown paper, pasteboard. or other paper-like material as a substituic
for the said leather covering. which materials are to be cut into the forms of
discs and packed on a shaft side by side and tightened up by nuts at each end.
the edge of the paper thus coming into contact with the cotton, which retains
the fibres of the cotton and cleans it better than leather.

as we, the said Charles Henry Robinson. John Fryer. and Abraham Dyson,
our executors, administrators, and assigns, should at any time agree with,
and no others. from time to time and at all times thereafter during the

vend, within the United Kingdom of Great Britain and Ireland. the Channel
Islands, and Isle of Man, an Invention for " 'CERTAIN IMPROVEMENTS IN APPA
RATUS CALLED GINS' FOR CLEANING SEED COTTON," upon the condition
(amongst others) that we, the said Charles Henry Roinson. John Fryer,
and Abraham Dyson. our executors or administrators. by an instrument in
writing under our. or two of our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed. and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Fryer and Abraham Dyson, do
hereby declare the nature of the said Invention, and in what manner the same
is to be performed. to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say):--
Our Invention relates to that part of cotton "gins" called the stripping
roller, and is usually covered with leather and grooved spirally around its
periphery.
The improvements consist in the employment, application, and use of mill-
board, brown paper, pasteboard, or other paper-like material as a substitute
for the said leather covering. which materials are to be cut into the forms of
discs, softened by steaming or soaking, and packed on a shaft side by side at

page_text: right angles to or diagonally to the shaft, and tightened up by nuts at each
end, after which the surface is turned up and grooved, the edge of the
paper thus coming into contact with the cotton. which retains the fibres of the
cotton and cleans it better than leather.
In order that the Invention may be better understood and explained in
detail. we have hereunto attached a Sheet of Drawings made upon a scale of
about three inches to the foot.
Fig. represents a front view of the spirally grooved roller, which may be
made of discs of millboard. pasteboard, or other paper-like material, or of
discs of felting or cocoa-nut fibre compressed. and either combined with paper
or not; Fig. 2 is an end view of the same shewing the form of perforated
disc employed.
In Fig. 1, a, a. is the shaft, on which the discs b, b. are placed side by side.
and are tightened or pressed together by the nuis c. c. which are prevented
from slackening by the lock nuts d, d.
Having now described the nature of the said Invention, together with
the method of carrying the same into practical effect. we wish it to be distinctly
understood that we claim the employment and use of the aforesaid materials.
either alone or combined, as a substitute for leather stripping rollers employed
in cotton gins, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, we, the said John Fryer and Abraham Dyson. have
hereunto set our hands and seals, this Sixteenth day of March, in the
year of our Lord One thousand eight hundred and sixty-five.
