IMPROVEMENTS IN STAMPING ON FLATTED PROAL
Year: 1866

page_text: LETTERS PATENT to Michel Spiquel, of No. 164, Rue St. Honoré, and
Eugène Henry Florange, of No. 106, Rue Vieille du Temple, and of 82,
Boulevard Sébastopol, all in Paris, in the Empire of France, Gold and
Silver Smiths for the Invention of "IMPROVEMENTS IN STAMPING ON FLATTED
PROVISIONAL SPECIFICATION left by the said Michel Spiquel and
Eugène Henry Florange at the Office of the Commissioners of Patents,
with their Petition, on the 23rd April 1866.
We, MICHEL SPIQUEL, of No. 164, Rue St. Honoré, and EUGÈNE HENRY
FLORANGE, of No. 106, Rue Vieille du Temple, and of 82, Boulevard
Sébastopol, all in Paris, in the Empire of France, Gold and Silver Smiths,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
STAMPING ON FLATTED OR UNPLATTED METALS," to be as follows:-
The object of the present Invention is to facilitate the production of designs
of various forms by means of moulds or dies, the requisite force or stamping
power being obtained by the aid of the hydraulic press, thus doing away with
the necessity of employing the usual balance or swing press and hammer, and
other means at present in use, which render the operations tedious and
costly.
On the metal table fixed on the piston of the press we place a mould
having a number of devices sunk thereon, or we make use of a metal box

page_text: or frame, in which we place as many moulds as we require, and varying in
form and design if desired, whether for forks, spoons, jewelry, bronze, or
military ornaments or fittings. These moulds are fixed in the box by any
ordinary means, such as screws passing through each side of the box, and thus
pressing or holding them firmly together. Fixed to the head of the press is
another box containing the corresponding moulds or dies, which are also
secured in a similar manner. The piston of the press on which the lower set
rests is then raised by means of pumps in the usual way, a plate of metal
having been previously placed on the moulds, they are then subjected to a
sufficient amount of pressure against the upper set to produce the required
impression.
When the manometer in connection with the press indicates the necessary
amount of pressure, the discharge cock is opened to allow the descent of the
piston so as to withdraw the stamped metal; the cock is then again closed
and a similar operation is repeated with another sheet of metal. All that is
required on withdrawing the stamped metal is to separate each article by
means of a cutting tool made to correspond with the article or design stamped
or moulded.
By this simple method a saving of labour equal to eighty per cent. is gained
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Michel Spiquel and Eugène Henry Florange in the Great
Seal Patent Office on the 22nd October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MICHEL
SPIQUEL, of 164, Rue St. Honoré, and EUGÈNE HENRY FLORANGE, of No. 106,
Rue du Vieille du Temple, and of 82, Boulevard Sébastopol, all in Paris, in
the Empire of France, Gold and Silver Smiths, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Michel Spiquel and Eugène Henry Florange, Her special licence that
we, the said Michel Spiquel and Eugene Henry Florange, our executors,
administrators, and assigns, or such others as we, the said Michel Spiquel and
Eugène Henry Florange, our executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times

page_text: 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 STAMPING ON FLATTED OR UNPLATTED METALS," upon the condition (amongst
others) that we, the said Michel Spiquel and Eugène Henry Florange, our
executors or administrators, by an instrument in writing under 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 per-
formed, 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 Michel Spiquel and Eugène Henry
Florange, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and accompanying Drawings, that is
to say :-
The object of the present Invention is to facilitate the production of designs
of various forms by means of moulds or dies, the requisite force or stamping
power being obtained by the aid of the hydraulic press, thus doing away with
the necessity of employing the usual balance or swing press and hammer; and
other means as at present in use, which render the operation tedious and
costly.
On the metal table fixed on the piston of the press we place a mould
having a number of devices marked thereon, or we make use of a metal box or
frame, in which we place as many moulds as we require, and varying in form.
or design as desired, whether for spoons, or forks, jewelry, bronze, or military
ornaments or fittings, or for hardware articles. These moulds are fixed in.
the box by any ordinary meaus, such as screws passing through each side of
the box, and thus pressing or holding them firmly together. Fixed to the
head of the press is another box containing the corresponding moulds, which
are also secured in a similar manner. The piston of the press on which the
lower set rests is then raised by means of pumps in the usual way, a sheet of
metal having been previously placed on the moulds, they are then subjected to
a sufficient amount of pressure against the upper set to produce the required
impression.
When the manometer in connection with the press indicates the necessary
amount of pressure, the discharge cock is opened to allow the descent of the
piston sufficiently low to withdraw the stamped metal, the cock is then again
closed and a similar operation is repeated with another sheet of metal.. All

page_text: that is required on withdrawing the stamped metal is to separate each article
by means of a cutting tool made to correspond with the article or design
stamped or moulded.
By this simple method a saving of labour equal to 80 per cent. is gained
over the old system, and the articles thus manufactured have all the finish of
the best workmanship.

Fig. 1 is a bydraulic press, one-tenth the size we make use of; a is the
capital or head of the press; b, the cylinder or lower part thereof; c, the
piston moving therein; d, d, d, are square columns connecting the cylinder
to the capital; e, e, e, e, e, e, e, e, are the caps to the columns for bearing the
strain of the pressure; f,f,f,f, are caps securing the columns to the head of
the press a, as well as to the cylinder b, by being bolted thereto; g is an iron
box containing the lower or sunken set of moulds; h is the metal table or top
to the piston c, on which the box is placed; i is the box containing the
orresponding or raised set of moulds, and is fixed to the head of the press by
any convenient means; j, Fig. 1, is the sheet of metal to be treated; k, k, k, k,
are adjusting screws, serving to press the moulds together and thus secure
them in the box; 1 is the pipe communicating with the pumps for forcing up
the piston. Fig. 2 represents the press with the piston lowered after having
completed an operation. In order to facilitate the stamping process the metal
intended to be employed may be first passed between two cylinders, see Fig. 3,
having the various objects to be produced sunk and raised on the respective
cylinders which in one single turn will give to the metal the thickness required
fr the various articles as shown, Fig. 5. In Fig. 3 a is the cylinder having
the design raised thereon; and b is the cylinder in which the same is sunk;
c is the sheet of metal passing between the two. Fig. 4 is a side view of
Fig. 8, a and b being the cylinders, and c the sheet of metal, which is
shown in Fig. 5, as having undergone this operation. Fig. 6 represents two
moulds, one, a, raised, and the other, b, sunk, as in Fig. 3, the difference being
that they are not cylindrical as represented in that Figure, the same result is
obtained from this as from the cylinders represented in Fig. 3. Fig. 7 shows
the box ready to receive the moulds. a, a, a, a, are the adjusting screws for
fixing the moulds. Fig. 8 the same furnished with 'moulds, a, b, c, d, e, f,
g, h, i, j, ready for use; Fig. 9, the same, having the moulds a, e, and h
removed; Figs. 10 and 11 and 12 are the moulds a, e, and h; Figs. 13, 14,
and 15, and lettered k, l, and m, may take the places vacated by the moulds
a, e, and h; Fig. 16, shows these moulds arranged in the vacant spaces caused
by the removal of those marked a, e, and h, thus it will be seen that the
moulds may be changed about as desired; Fig. 17 is a plate of metal having

page_text: undergone one single pressure from the press, and bearing the impress of the
moulds a, b, c, d, e, f, g, h, i, and j; Fig. 18 is the upper portion of the
cutting tool for separating the forks stamped, and Fig. 19 is the lower part
of the same; Fig. 20 is a plan of the same; Figs. 21 and 22 are articles cut
from the sheet (Fig. 17) by the tool; Fig. 23 represents the remaining portion
of the metal after the pieces a, b, c, d, e, f, g, h, i, and j have been cut out;
Fig. 24 is the upper part of a cutting tool for separating the spoons, and
Fig 25 is the lower part thereof; Fig. 26 is a plan of the same; Figs. 27
and 28 are spoons cut from the metal sheet; Fig. 29 is the same box con-
taining moulds of various designs for ornaments of different kinds; Fig. 30 is
the corresponding box.
By the above description it will be seen that we can stamp any kind of
device or devices at the same time.
The boxes are made in wrought iron, and the moulds and cutting tools in
tempered steel.
Having thus described our Invention, what we claim and desire to secure
by Letters Patent is, the mode of stamping various articles of any desired
form in metal, as herein-before described and illustrated by the accompanying
Drawings.
In witness whereof, we, the said Michel Spiquel and Eugène Henry
Florange, have hereunto set our hands and seals, this Thirty-first
day of July, in the year of our Lord One thousand eight hundred and
sixty-six.
