""
PROVISIONAL SPECIFICATION left by the said Samuel Smily at the
Office of the Commissioners of Patents, with his Petition, on the
7th December 1874.
I, SAMUEL SMILY, of Upper Clapton, in the County of Middlesex,
do hereby declare the nature of the said Invention for “AN IMPROVED
METHOD OF STAMPING OR PRESSING DESIGNS ON METALS, AND IN THE DIES FOR
THAT PURPOSE," to be as follows :—
This Invention consists in stamping or pressing designs on metals by
means of hydraulic pressure instead of by percussion as heretofore, also
in the construction of the dies to accomplish the above object and to
render them less costly than at present,

page_text: In order to carry out this Invention I propose to construct the dies as
follows (for the handle of a spoon for example):-The designs required
are cut or cast on steel or other suitable metal in the usual way, but
instead of having a box dic it is simply composed of two plates of steel
or other suitable metal, having the required design cut or cast on each;
and on the top of the said plates or dies (and coming in contact with
that surface which has not the design upon it) I place layers of different
metals, such as malleable cast iron, cast iron, and brass, the said plates
rendering the dies less liable to fracture than heretofore. The said die
plates are provided with holes for pins to pass through, or are kept in
position by other suitable means. I then press the plates and dies by
hydraulic pressure in order to stamp the handle aforesaid.
Metals stamped or pressed as above will be more durable, being
rendered harder than those stamped or struck by the present method.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Smily in the Great Seal Patent Office
on the 7th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
SMILY, of Upper Clapton, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of December, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Samuel Smily, Her special licence,
that I, the said Samuel Smily, my executors, administrators,. and
assigns, or such others as I, the said Samuel Smily, 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, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
METHOD OF STAMPING OR PRESSING DESIGNS ON METALS, AND IN THE DIES FOR THAT-
PURPOSE," upon the condition (amongst others) that I, the said Samuel
Smily, my executors or administrators, by an instrument in writing.

page_text: 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 Samuel Smily, 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 :—
This Invention consists in stamping or pressing designs on metals by.
means of hydraulic pressure instead of by percussion as heretofore, also
in the construction of the dies to accomplish the above object and to
render them less costly than at present.
In order to carry out this Invention I propose to construct the dies as
follows (for the handle of a spoon for example) :-The designs required
are cut, cast, or pressed on steel or other suitable metal in the usual way,.
but instead of having a box die it is simply composed of two plates of
steel or other suitable metal having the required design cut or cast on
each; and on the top of the said plates or dies (and coming in contact
with that surface which has not the design upon it) I place layers of
different metals, such as malleable cast iron, cast iron, and brass, the
said plates rendering the dies less liable to fracture than heretofore.
The said dies are provided with holes for pins to pass through, or
are kept in position by other suitable means. I then press the plates
and dies by hydraulic pressure in order to stamp the handle afore-
said.
Metals stamped or pressed as above will be more durable, being
rendered harder than those stamped or struck by the present method.
And in order to explain my said Invention more fully I now proceed
to describe the means by which it may be carried into practical effect,
reference being had to the illustrative Sheet of Drawing accompanying
these Presents, and to the numeral figures and letters of reference
marked thereon, respectively as follows:-

page_text: sponding holes a³, by means of which the dies are held together in
position. B, B³, are layers or plates of malleable cast iron, cast iron,
brass, or other suitable metal; C, C', are also layers or covers of
metal.
Figure 2 shews the dies, layers, and covers together.
Figures 3 and 4 are side views and plans of different methods of
holding the dies in position, such for example as by means of half balls
with corresponding sockets, Figure 3, or V projections with grooves,
Figure 4, or other suitable means. The plates and dies are placed under
an hydraulic press in order to stamp the article placed between them.
Having now described and set forth the nature and object of my said
Invention for "An Improved Method of Stamping or Pressing Designs
on Metals, and in the Dies for that Purpose," I would remark in con-
clusion that I hereby declare my Invention to consist in, and I claim,
the improved method of stamping or pressing designs on metals, and the
dies for that purpose, substantially as described and represented.
In witness whereof, I, the said Samuel Smily, have hereunto set
my hand and seal, this Third day of June, in the year of our
Lord One thousand eight hundred and seventy-five.
Signed in my presence on
the 3rd June 1875.
W. H. BURRELL.
