page_text: LETTERS PATENT to Théodore Ramspacher, Civil Engineer, and Chris-
tophe Frédéric Schmidt, Tailor, of 2, Rue Ste Appoline, Paris, France,
for the Invention of " PREPARING WIRE GAUZE TO RENDER IT APPLICABLE
TO VARIOUS PURPOSES."
Sealed the 17th July 1860, and dated the 25th January 1860.
PROVISIONAL SPECIFICATION left by the said Théodore Ramspacher and
Christophe Frédéric Schmidt, at the Office of the Commissioners of
Patents, with their Petition, on the 25th January 1860.
We, THEODORE RAMSPACHER, Civil Engineer, and CHRISTOPHE FREDERIC
SCHMIDT, Tailor, of 2, Rue Ste Appoliue, Paris, France, do hereby declare
the nature of the said Invention for "PREPARING WIRE GAUZE TO RENDER IT
APPLICABLE TO VARIOUS PURPOSES," to be as follows, that is to say :-
Our Invention consists in covering metallic gauze or tissues either with
metals by means of galvanization, or with gummy substances, such as
caoutchouc, gutta percha, marine glue, linseed oil, resin, tar, and other
matters or substances. The metallic tissues thus prepared are afterwards
united to pieces of cloth, leather, or other textile fabrics, so as to give them
greater strength, while they retain their lightness, and are rendered water-
proof. This new material may be employed for manufacturing bands,
cuirasses, soles for boots and shoes, shakos, helmets, articles of furniture,
[Price 8d.]

pipes, washers for steam engines, and generally for the uses to which metallic
tissues thus prepared may be employed with advantage
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Théodore Ramspacher and Christophe Frédéric Schmidt, iu
the Great Seal Patent Office on the 24th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THEODORE
RAMSPACHER, Civil Engineer, and CHRISTOPHE FREDERIC SCHMIDT, Tailor, of
2, Rue Sainte Appoline, Paris, (France,) send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of January, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Théodore Ramspacher and Christophe Frédéric Schmidt, Her special
licence that we, the said Théodore Ramspacher and Christophe Frédéric
Schmidt, our executors, administrators, and assigns, or such others as we, the
said Théodore Ramspacher and Christophe Frédéric Schmidt, our executors,
administrators, or 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 of "PREPARING WIRE GAUZE TO RENDER IT
APPLICABLE TO VARIOUS PURPOSES," upon the condition (amongst others) that
we, the said Théodore Ramspacher aud Christophe Frédéric Schmidt, 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
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 Théodore Ramspacher and Christophe
Frédéric Schmidt, do hereby declare the nature of the 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:-
Our Invention consists in filling the meshes of metallic gauze either with
gummy or metallic substances, or partly with gummy and partly with metallic

page_text: substances.
The metallic gauze thus treated is afterwards covered with
leather or other suitable fabric, and is rendered applicable for the manufacture
of straps or bands, cuirasses, soles of boots and shoes, shakos, helmets, articles
of furniture, carpets, the roofs of houses and other buildings, shop window
shutters, camp and other bedsteads, girths (sangles, hammocks), pipes, cables,
screens, vases, tents, reins, traces, gutters, straps for guns, sacks, belts, the
tops of epaulettes, drapery and decorations for theatres, fire buckets and
washers for steam engines, and other articles for the manufacture of which
metallic gauze thus prepared is susceptible of being usefully applied.
We fill the meshes of the wire gauze with metallic substances, either by
immersing the metallic gauze cut to the required shape in molten metal, or by
the employment of the galvanic battery. By this means the meshes will be
completely or only partially closed, thus forming a metallic plate; the weft
wires being, as it were, soldered to the warp wires, and if a pressure be
applied, on any part of this wire fabric it will no longer be supported merely
by the wires to which it is applied, but will be distributed over all the wires.
For most applications we close or we finish the closing of the meshes with
gummy substances, such as india-rubber, gutta percha, marine glue, linseed
oil, fish glue, resins, tar, either alone or mixed together, or with other sub-
stances. These substances are employed hot, or in a state of solution. We
introduce the metallic gauze into the said solution, and afterwards withdraw it
and apply the leather or other suitable fabric thereto, which we fix thereon by
passing them through the rollers of a rolling machine, or under a press.
We employ various forms of metallic gauze when intended for the manu-
facture of straps and bands and other like articles, which are first coated with
a gummy substance, and then covered with leather or other suitable fabric,
viz. We employ, firstly, ordinary wire gauze; secondly, metallic gauze
without weft, that is to say, composed merely of longitudinal wires; thirdly,
metallic gauze, the meshes of which are in part filled with metallic sub-
stances; fourthly, metallic gauze, with its weft made of a vegetable or animal
substance.
The metallic gauze to be, employed for the manufacture of straps should
have its weft separated, and the warp threads or wires close together; the
separation ofthe weft causes the warp threads to be much less obstructed, and
there is less risk of disordering them at the parts where they are in contact
with the weft. The warp threads thus placed two by two form small lozenges
lengthened out, which are filled with a gummy substance, and form as many
small springs, which give to the band or strap the required elasticity. The
metallic gauze to be employed for the manufacture of straps are wove in the

page_text: form of girths. On each side several threads are passed into the same tooth
of the comb, and by this means we obtain a kind of selvage, which gives great
strength to the strap.
Several superposed thicknesses of wire gauze are employed for cuirasses and
other applications. The metallic.cloth for the manufacture of screens or for
furniture fittings are gilt or silvered. Silvered designs may be made on a gilt
ground, and vicè versà.
Having now described the nature of our said Invention, and the manner of
carrying the same into effect, we wish it to be understood that we do not
confine ourselves to the precise details herein-before laid down. What we
claim is;
First, the covering or filling the meshes of metallic gauze with metallic or
gummy substances, and afterwards uniting it to pieces or bands of leather,
india-rubber, or other suitable fabric to render it applicable to various useful
purposes, as herein-before described.
Secondly, the covering or filling the meshes of metallic gauze partly with.
metallic and partly with gummy substances, as herein before described.
Thirdly, the employment of metallic gauze, with open meshes, united to
leather or other suitable fabric coated with a gummy substance, for the
manufacture of straps and other useful articles, as herein-before described.
Fourthly, the employment of metallic gauze, without weft, applied to
leather or other suitable fabric by means of a gummy substance, for the
manufacture of straps and other useful articles, as herein-before described.
Fifthly, the employment of wire gauze, with a weft composed of a vegetable
or animal thread, covered with gum and leather, for the manufacture of straps,
as herein-before described.
In witness whereof, we, the said Théodore Ramspacher and Christophe
Frédéric Schmidt, have hereto set our hands and seals, this Twentieth
day of July, in the year of our Lord One thousand eight hundred
and sixty.
RAMSPACHER.
