Year: 1864

page_text: LETTERS PATENT to Richard Kay, of Heywood, in the County of Lan-
caster, Cotton Spinner, John Manock, of the same Place, Manager, and
George Dakin, of the same Place, Roller Coverer, for the Invention of
"IMPROVEMENTS IN A CERTAIN DESCRIPTION OF ROLLERS' EMPLOYED IN APPA-
RATUS FOR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER FIBROUS
SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Richard Kay, John
Manock, and George Dakin, at the Office of the Commissioners of
Patents, with their Petition, on the 2nd August 1864.
We, RICHARD KAY, of Heywood, in the County of Lancaster, Cotton
Spinner, JOHN MANOCK, of the same Place, Manager, and GEORGE DAKIN, of
the same Place, Roller Coverer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN A CERTAIN DESCRIPTION OF 'ROLLERS' EMPLOYED
IN APPARATUS FOR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER
FIBROUS SUBSTANCES," to be as follows:-
Our Invention relates particularly to that description of rollers employed in
spinning called "drawing rollers," between which the fibres are drawn out or
lengthened, and which are sometimes composed of lead covered with leather.
The Invention consists in coating or covering these "rollers" with an exterior

page_text: surface of copper, either by the process of electrotyping, or by soldering the
cylinder of copper on the roller, or by other equivalent means, whereby the
usual covering of the leather is dispensed with, and a more regular and true
surface is maintained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Kay, John Manock, and George Dakin, in the
Great Seal Patent Office on the 1st February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RICHARD
KAY, of Heywood, in the County of Lancaster, Cotton Spinner, JOHN MANOCK,
of the same Place, Manager, and GEORGE DAKIN, of the same Place, Roller
Coverer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of August, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Richard Kay, John Manock, and George Dakin, Her special license
that we, the said Richard Kay, John Manock, and George Dakin, our execu-
tors, administrators, and assigns, or such others as we, the said Richard Kay,
John Manock, and George Dakin, 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 term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN A CERTAIN DESCRIPTION OF ROLLERS' EMPLOYED IN APPARATUS
FOR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that we, the said Richard Kay, John
Manock, and George Dakin, our executors or administrators, by an instru-
ment in writing under our, or one 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 I, the said Richard Kay, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-

page_text: Our Invention relates particularly to that description of rollers employed in
spinning called "drawing rollers," between which the fibres are drawn out or
lengthened, and which are sometimes composed of lead covered with leather.
The Invention consists in coating or covering these "rollers with an
exterior surface of copper, either by the process of electrotyping, or by soldering
the cylinder of copper on the roller, or by other equivalent means, whereby
the usual covering of leather is dispensed with, and a more regular and true
surface is maintained.
The internal roller is first cast or otherwise formed and turned to a true
surface; the shafts or pins thereof are then coated with varnish or other
protection, and the roller is then placed in a solution of sulphate of copper,
and attached to a battery, and is electrotyped in the ordinary manner, and
when the coating is sufficiently thick the roller is removed, and the surface
turned up in a lathe.
We would here remark that since the filing of the Provisional Specification
for our said Invention we have ascertained that the means of soldering the
copper cylinder on to the roller as therein described is not so novel or original
nor of such utility as we then considered it to be, and we therefore hereby
disclaim that portion of the Invention.
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 coating or covering rollers used in machinery for
spinning cotton, and composed of lead (or other heavy metal) with copper
by means of the process of electrotyping, as herein-before described and
set forth.
In witness whereof, I, the said Richard Kay, have hereunto set my
hand and seal, this Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-five.
RICHARD KAY. (L.B.)
