CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF ROLLERS OR CYLINDERS TO BE EMPLOYED FOR PRINTING CALICO AND OTHER SURRACES" PROVISIONAL SPECIFICATION
Year: 1857

page_text: LETTERS PATENT to John Davies Mucklow, of Blackford Bridge, in the
County of Lancaster, Calico Printer, for the Invention of "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE OF ROLLERS OR CYLINDERS TO BE
EMPLOYED FOR PRINTING CALICO AND OTHER SURRACES"
PROVISIONAL SPECIFICATION left by the said John Davies Mucklow at
the Office of the Commissioners of Patents, with his Petition, on the
11th May 1857:
I, JOHN DAVIES MUCKLOW, of Blackford Bridge, in the County of Lancaster,
Calico Printer, do hereby declare the nature of my said Invention for "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE OF ROLLERS OR CYLINDERS TO BE EMPLOYED FOR
PRINTING CALICO AND OTHER SURFACES," to be as follows:-
My Invention relates to the manufacture of such rollers or cylinders which
have hitherto been generally made entirely of copper, and consists in so
manufacturing the rollers or cylinders, that the large quantity of this metal,
and consequent value of such rollers or cylinders, may be considerably
reduced.
I manufacture or construct the printing roller or cylinder of iron, which
may either be made hollow, and used upon a mandril in the printing machine
(as copper rollers now are), or may, if preferred, be made solid throughout,
and used without the mandril, and without being restricted to any peculiar
state of the metal, whether it be called wrought, cast, malleable, or otherwise.
Upon the surface of this iron cylinder I engrave or otherwise produce the
pattern or design to be printed, and afterwards coat or cover the engraved
surface of the roller or cylinder with nickel, copper, or any other suitable
metal or mixture of metals, in order to prevent any oxydation or deleterious

page_text: effect of acids or other causes occurring in the process of printing. This
coating or covering must necessarily be thin in substance, and is intended only
as it were as a varnish or coating to protect the engraved surface of the
printing cylinder or roller. The coating or covering is effected by the deposi-
tion of the finer metals upon the iron roller or cylinder by the well-known
process of "electrotyping" by means of galvanic or voltaic electricity.
Although I have above stated iron to be the base or body of the roller I
do not limit myself to that metal, as I mean to employ any inferior metal that
will have sufficient texture, surface, and durability for engraving upon and
printing from, and the same with the coating or covering electrotyped there-
upon but at present I prefer nickel or copper.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Davies Mucklow in the Great Seal Patent Office on the
11th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DAVIES MUCKLOW, of Blackford Bridge, in the County of Lancaster, Calico
Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Davies Mucklow, Her especial license that I, the said John Davies
Mucklow, my executors, administrators, and assigns, or such others as I, the
said John Davies Mucklow, my 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,
uise, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE OF ROLLERS OR CYLINDERS TO BE EMPLOYED
FOR: PRINTING CALICO AND OTHER SURFACES," upon the condition, amongst
others, that I, the said John Davies Mucklow, by an instrument in writing
under my hand and seal, 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..

page_text: NOW KNOW YE, that I, the said John Davies Mucklow, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, that is to say:―
My Invention relates to the manufacture of such rollers or cylinders which
have hitherto been generally made entirely of copper, and consists in so
manufacturing the rollers or cylinders, that the large quantity of this metal,
and consequent value of such rollers or cylinders, may be considerably
reduced.
I manufacture or construct the printing roller or cylinder of iron or of
alloys, which may either be made hollow, and used upon a mandril in the
printing machine (as copper rollers now are), or may, if preferred, be made
solid throughout, and used without the mandril, and without being restricted
to any peculiar state of the metal, whether it be called wrought, cast,
malleable, or otherwise. Upon the surface of this iron or composition cylinder
I engrave or otherwise produce the pattern or design to be printed, and after-
wards coat or cover the engraved and entire surface of the roller or cylinder
with nickel, copper, brass, or any other suitable metal or mixture of metals,
in order to prevent any oxydation or deleterious effect of acids or other
causes occurring in the process of printing. This coating or covering must
necessarily be thin in substance, and is intended only as it were as a varuish
or coating to protect the engraved or other surface of the printing cylinder or
roller. The coating or covering is effected by the deposition of the finer
metals upon the iron or composition rollers or cylinders by the well-known
process of "electrotyping" by means of galvanic or voltaic electricity.
Although I have above stated iron to be the base or body of the roller I
do not limit myself to that metal, as I mean to employ any inferior metal or
alloy that will have sufficient texture, surface, and durability for engraving.
upon and printing from, and the same with the coating or covering electro-
typed thereupon; but I prefer nickel, copper, or brass.
In witness whereof, I, the said John Davies Mucklow, have hereunto set
my hand and seal, this Ninth day of November, in the year of our
Lord One thousand eight hundred and fifty-seven.
JOHN DAVIES MUCKLOW. (L.S.)
