page_text: LETTERS PATENT to Isaac Taylor, of Stanford Rivers, in the County of
Essex, for the Invention of "IMPROVEMENTS IN MANUFACTURING METALLIC
CYLINDERS USED IN PRINTING CALICO AND OTHER FABRICS, AND IN IMPARTING
ENGRAVINGS TO METALLIC CYLINDERS USED FOR SUCH PURPOSES.".
Sealed the 9th July 1858, and dated the 11th January 1858.
PROVISIONAL SPECIFICATION left by the said Isaac Taylor at the Office
of the Commissioners of Patents, with his Petition, on-the 11th January
1858.
I, ISAAC TAYLOR, of Stanford Rivers, in the County of Essex, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN MANUFACTURING
METALLIC CYLINDERS USED IN PRINTING CALICO AND OTHER FABRICS, AND IN.
IMPARTING ENGRAVINGS TO METALLIC CYLINDERS USED FOR. SUCH PURPOSES," to be
as follows:-
T:
The first part of my Invention consists of forming metallic cylinders used
for printing calico and other fabrics, by bending plates of copper
or other
metal in such manner as that the two abutting edges of such cylinders being
suitably held together, by solder or otherwise, at their inner parts, shall be
pressed together at the outer parts by apparatus.consisting of a strong external
containing cylinder, made by preference in two halves longitudinally, and
".

page_text: retained securely in position by a frame or outer cylinder, so that a copper
shell or metallic cylinder, enclosed in the above-named cylinder in halves, may
be pressed from the interior outwards into the said retaining cylinder, so as to
close the outer parts of the abutting edges and thus form a continuous surface.
For the purpose of applying sufficient force internally, it is preferred to
employ two mills or rollers mounted on the opposite sides of an axis, and these
being caused to rotate within the copper shell, and to advance slowly from end
to end thereof in a helical direction by means of a screw and nut and suitable
driving gear.
My Invention consists, secondly, in the means of imparting an engraving to
thin copper shells for printing calico and other fabrics, inasmuch as heretofore
has been found very difficult to put an engraving by mill and dye upon thin
metallic shells. My Invention obviates this difficulty by the following means:-
The shell which is to receive the engraving is lodged within a cylinder, similar
to the one above mentioned, and of suitable dimensions and sufficient strength;
then an engraving, whether raised or depressed upon the inner or concave
surface of a curved plate or hoop, or of several such plates or hoops, is-placed
between the said shell and the containing cylinder, the raised or the indented
work being thus brought into contact with the exterior or convex surface of
the shell. Mechanic force is then applied to the interior surface of the shell
in any convenient manner, as, for instance, by passing a steel plunger through
it lengthwise, or by means of steel mills revolving as above described, in a
helix direction through it. The metallic crust or substance of the shell is thus
driven by pressure fully home upon the raised or indented engraving, and a
perfect impression of the work is obtained upon the shell free from burgh, and
while the true cylindrical form of the shell is preserved.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Isaac Taylor in the Great Seal Patent Office on the
10th July 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAAC So
TAYLOR, of Stanford Rivers, in the County of Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of January, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto 35

me, the said Isaac Taylor, Her special licence that I, the said Isaac
Taylor, my executors, administrators, and assigns, or such others as I, the
said Isaac Taylor, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times, there
after 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
MANUFACTURING METALLIC CYLINDERS USED IN PRINTING. CALICO AND OTHER
FABRICS, AND IN IMPARTING ENGRAVINGS TO METALLIC CYLINDERS USED FOR
BUCH PURPOSES," upon the condition (amongst others) that I, the said Isaac
Taylor, my executors or administrators, by an instrument in writing under
my, 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 Isaac Taylor, 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 thereof, that is to say:-
In addition to the method of forming metallic shells as claimed by me and
described in my Specification of Patent dated June 2nd 1854, which was for
forming metallic cylinders by bending plates of copper or other metal in such
manner that the two abutting edges of such cylinders being suitably held to-.
gether by solder, or otherwise, at their inner parts, shall be pressed together at
their outer parts (where the edges of metal of the cylinder come together without
the interposition of solder) by mechanic force applied at the outer surface;
whereas my present Invention consists in the application of such force on, the
seam or joint, not only externally but also internally, and this is done as well
for completing the joint as for giving a true cylindrical form to the shell
throughout its whole surface.. For securing these purposes, I now apply force
also to the interior of the shell in the following manner:-The machine or
apparatus which I employ consists in a strong external containing cylinder,
which, for convenience in its use, is made in two halves, longitudinally, and
which are retained securely in position by a frame or outer cylinder, so that a
copper shell or metallic cylinder enclosed in the above-named cylinder in
halves may be pressed from the interior outwards into the same, so as more
completely to close the outer parts of the abutting edges, and thus to form a

page_text: continuous surface, and also to give truth of form to the shell throughout.
For the purpose of applying sufficient force internally to the shell, so as to
effect the two above-named intentions, it is preferred to employ two or three
mills or rollers mounted on the opposed sides of an axis, and these being
caused to rotate within the 'd
"copper' shell, and to advance slowly from end to
end thereof 'in a helical direction by means of a screw and nut and suitable
driving gear. Or, the same purposes may be secured by passing a steel die or
plunger through the shell from end to end, and which, in that case, might be
made to rotate or not in its passage through the shell. I would remark, that
I am aware that it is not new to force cylinders composed of sheet metal into
strong external dies or cylinders by internal pressure, I do not therefore claim
the same generally, but only as a means of forming the description of joint or
seam to cylinders such as are described in the 'Specification of my said former
Patent, that is to say, joints or seams which at the outer surface consist
simply of the abutting edges or surfaces of the metal, of which the cylinder is
composed, without the interposition of solder.
My Invention consists, secondly, in the means of imparting an engraving to
thin copper shells for printing calico' and other fabrics. Inasmuch as heretofore
it has been found very difficult to put an engraving by mill and dye upon thin
metallic shells. My Invention obviates this difficulty by the following means:-
The shell which is to receive the engraving is lodged within a cylinder similar
to the one above mentioned, and of suitable dimensions and sufficient strength;
then an engraving, whether raised or depressed upon the inner or concave
surface of a curved plate or hoop, or of several such plates or hoops, is placed
between the said shell and the containing cylinder, the raised or the indented
work being thus brought into contact with the exterior or convex surface of
the shell. Mechanic force is then applied to the interior surface of the shell
in any convenient manner, as, for instance, by passing a steel plunger through
it lengthwise, or by means of steel mills revolving as above described in a helix
direction through it. The metallic crust or "substance of the shell is thus
driven by pressure fully home upon the raised or indented engraving, and a
perfect impression of the work is obtained upon the shell free from burgh, and
while the true cylindrical form' of the shell is preserved.
T I would 'here remark, that I am aware that it has before been proposed
to employ dies or moulds to fit the outside of the cylinder to be engraved, and
to engrave the interior surfaces of such dies or moulds, and I would have it
understood that 'I make no claim thereto, and I declare that my improvements
consist in interposing between the containing strong cylinder an engraved plate

page_text: or hoop or several of such plates or hoops between the exterior of the shell
and the interior of the containing cylinder.
In witness whereof, I, the said Isaac Taylor, have hereunto set my hand
and seal, this Ninth day of July, in the year of our Lord One thousand
eight hundred and fifty-eight.
Witness,
HENRY WILLIAM CARPMAEL.
