page_text: TTERS PATENT to John Smith, of 8, Upper Fountain Place, City
Road, in the County of Middlesex, William Henry Smith, likewise
of 8, Upper Fountain Place, City Road, in the County of Middle-
sex, and Alexander Williams, of 15, Seething Lane, Great Tower
Street, in the City of London, Manufacturers, for the Invention of
"CERTAIN IMPROVEMENTS IN METALLIC PLATES, AND IN PRODUCING
DEVICES OR ORNAMENTAL PATTERNS THEREON, AND IN THE APPARATUS
AND MACHINERY TO BE USED FOR SUCH PURPOSES."
Sealed the 1st September 1853, and dated the 2d March 1853.
O PROVISIONAL SPECIFICATION left by the said John Smith, William
Henry Smith, and Alexander Williams at the Office of the Com-
missioners of Patents, with their Petition, on the 2d March 1853.
We, JOHN SMITH, WILLIAM HENRY SMITH, and ALEXANDER WILLIAMS,
do hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS IN METALLIC PLATES, AND IN PRODUCING DEVICES OR ORNAMENTAL
PATTERNS THEREON, AND IN THE APPARATUS AND MACHINERY TO BE USED
POR SUCH PURPOSES," to be as follows, viz. :-

page_text: This Invention consists in embossing or impressing in a continuous
manner on the surfaces of metallic plates any desired device, pattern,
or ornament by means of metallic rollers impressed, chased, or engraved,
when in a soft state, with the required pattern, device, or ornament, in
reverso of what is intended to be produced on the plate, and afterwards
hardened.
The plates are passed between two rollers, the one having the pattern
thereon, and the other being a plain pressure roller; but in order to
bring the plate out flat it is passed through flatting rollers after passing
through the rollers aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Smith, William Henry Smith, and Alexan-
der Williams, in the Great Seal Patent Office, on the 1st Septem-
ber 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc,
JOHN SMITH, of 8, Upper Fountain Place, City Road, in the County of
Middlesex, WILLIAM HENRY SMITH, likewise of 8, Upper Fountain
Place, City Road, in County of Middlesex, and ALEXANDER WILLIAMS,
of 15, Seething Lane, Great Tower Street, in the City of London,
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of March, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said John Smith, William Henry Smith, and
Alexander Williams, our executors, administrators, and assigns, Ier
special licence that we, the said John Smith, William Henry Smith,
and Alexander Williams, our executors, administrators, and assigns,
or such others as we, the said John Smith, William Henry Smith,
and Alexander Williams, our executors, administrators, and assigns,
should at any time agree with, and no others, from time to timo
and at all times thereafter during the term therein expressed, should

page_text: 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 "CERTAIN IMPROVEMENTS IN ME-
TALLIC PLATES, AND IN PRODUCING DEVICES AND ORNAMENTAL PATTERNS
THEREON, AND IN THE APPARATUS AND MACHINERY TO BE USED FOR SUCH
PURPOSES," upon the condition (amongst others) that we, the said
John Smith, William Henry Smith, and Alexander Williams, by an
instrument in writing under our hands and seals, or the hand and scal
of one of us, 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 Smith, William Henry
Smith, and Alexander Williams, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
thereof, that is to say:
Our Invention consists in and has reference to improvements in
metallic plates, especially tin plates and plates of similar hardness, by
giving superior surfaces thereto, and by producing devices or ornamental
patterns thereon, and in the apparatus and machinery used for such
purposes in regard to the specialties in the construction thereof, in
order to subserve these objects. We can obtain a superior surface, as
hereafter stated; and we can produce devices or ornamental patterns by
embossing or impressing in a continuous manner on the surfaces of
metallic plates any desired device, pattern, or ornament by means of
steel or steel-surface rollers impressed, chased, or engraved, when in a
soft state, with the required device, pattern, or ornament (in reverse of
what is intended to be produced on the plate), and afterwards hardened.
The plates are to be passed through two rollers, one having the
pattern thereon, and the other being a pressure or counter roller; and
when it is required to bring the plate out flat it must be passed through
ordinary bending or flattening rollers, which may, if desired, be attached
to the first-named rollers.
To enable the practical man to construct and prepare the rollers first

page_text: named it will be sufficient to state that they may be of the general form
and structure usually adopted for rolling metals as now practised; the
size and form being governed, of course, by the circunstances of the
case; and, like those for paper embossing, they will be first formed in
soft metal, and then embossed, engraved, or impressed by any convenient
method, and then hardened.
In this Invention the pressure or counter roller is not to be of
hardened metal, but is to be a soft metal roller; for instance, a soft
wrought-iron roller; as a hard metal roller would present too unyielding
a pressure to the plate under operation, and thus render it difficult to
produce the impression required thereon.
The two rollers, the hard or impression roller, and tho soft or counter
roller, are to be connected and geared together so as to form a pair of
rolls, as adopted with rollers for rolling metals, and motion communi-
cated in the same manner; and the bending or flattening rollers may be
of any ordinary kind.
Having now described the nature of our said Invention, and in what
manner the same is to be performed, we further declare that we claim
in respect thereto the improvements in metallic plates, especially tin
plates, and in producing devices or ornamental patterns thereon by the
use and adoption of the improvements in the apparatus and machinery
to be used for those purposes, as herein-before set forth and described.
In witness whereof, we, the said John Smith, William Henry
Smith, and Alexander Williams, have hereunto set our hands
and seals this Twenty-ninth day of August, in the year of our
Lord One thousand eight hundred and fifty-three.
