Iм- PROVEMENTS IN THE MANUFACTURE OF LEATHERN ACCOUTREMENTS
Year: 1862

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County
of Middlesex, Engineer and Patent Agent, for the Invention of "Iм-
PROVEMENTS IN THE MANUFACTURE OF LEATHERN ACCOUTREMENTS." -A
communication from abroad by Messrs. Adolphe Blanc and Jean Frédéric
Auguste Marty, both of 29, Boulevart St. Martin, Paris.
Sealed the 3rd October 1862, and dated the 11th April 1862.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 11th
April 1862.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF LEATHERN ACCOUTREMENTS," to be
as follows:
This Invention relates to the employment of metal fastenings for uniting
leather, such as for military or civil accoutrements, in place of the threads of
vegetable material hitherto used for sewing the different parts together. The
fastenings 1 employ may consist of screws or rivets of copper, iron, or other
metal.
The feature of the Invention consists in the new application of metal
fastenings, such as screws or rivets (which are well known as employed for
various other useful purposes) for the manufacture of military and other
accoutrements. This may bo effected with great facility. Thus, in uniting

page_text: the parts with screws, I first arrange the articles in the same way as if they
were to be sewn, either on a wood support covered with strong sheet iron, or
on a mandril or cast-iron form, according to the shape of the articles; they
are then placed in a machine ordinarily used for screwing the parts of boots
and shoes together. The screws are formed of wire screw-threaded to a
certain extent, according to the amount of work to be effected; these pene-
trate the two pieces of leather to be united until they come in contact with
the iron support or mandril, the impulse given by the machine being sufficient
to rivet the end; the wire screw may then be cut off by the shears, and the
operation repeated according to the number of screws to be put into the
article; when complete it is only necessary to smoothen with a hammer or
file any roughness left by the shears. When employing rivets, the parts to
be united have holes previously punched in them of a size according to the
diameter of the rivets made use of. The rivets when applied for the above
purposes should be turned in a lathe, be highly polished, and of a slightly
conical form. After the rivets have been introduced into the holes made for
their reception I apply a head of the same metal to each, on which is rivetted
the projecting part of the rivet, either with a hammer or by a single blow of
a striker of sufficient power. I may employ either of the above methods
of fastening for all kinds of military or other accoutrements, such as for
railway equipments, belts, cartridge boxes, sword or bayonet scabbards or
sheaths, leggings, cases for military standards, and other similar purposes;
either method ensures the same solidity and durability.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Offie on the 9th
October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent; send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of April, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Clark, Her special licence that I, the said William Clark, my exe-
cutors, administrators, and assigns, or such others as I, the said William Clark,
my executors, administrators, and assigns, should at any time agree with, and

page_text: 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 "IMPROVEMENTS IN THE MANU-
PACTURE OF LEATHERN ACCOUTREMENTS," a com" to me from abroad by Messrs.
Adolphe Blanc and Jean Frédéric Auguste Marty, both of 29, Boulevart St.
Martin, Paris, upon the condition (amongst others) that I, the said William
Clark, my executors or administrators, by an instrument in writing 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 William Clark, 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, .
reference being had to the Sheet of Drawings hereunto annexed, and to the
letters and figures marked thereon (that is to say):
This Invention relates to the employment of metal fastenings for uniting
leather, such as for military or civil accoutrements, in place of the threads of
vegetable material hitherto used for sewing the different parts together. The
fastenings 1 employ may consist of screws or rivets of copper, iron, or other
metal.
The feature of the Invention consists in the new application of metal
fastenings, such as screws or rivets, which are well known as employed for
various other useful purposes, for the manufacture of military and other
accoutrements. This may be effected with great facility; thus, in uniting the
parts with screws, I first arrange the articles in the same way as if they
were to be sewn either on a wood support covered with strong sheet iron, or
on a mandril or cast-iron form, according to whether the articles are flat or
concave; they are then placed in a machine ordinarily used for screwing the
parts of boots and shoes together, represented at Fig. 1. Tho screws are
formed of wire screw-threaded to a certain extent, according to the amount of
work to be effected; these penetrate the two pieces of leather to be united
until they come in contact with the iron support or mandril, the impulse
given by the machine being sufficient to rivet the end; the wire screw may then
be cut off by the shears, and the operation repeated according to the number of
screws to be put into the article. When complete it is only necessary to
smoothen any rougliness left by the shears with a hammer or file. When

page_text: employing rivets the parts to be united have holes previously punched in them
of a size according to the diameter of the rivets made use of. The rivets
when applied for the above purposes should be turned in a lathe, be highly
polished, and of a slightly conical form, as at Fig. 2. After the rivets have
been introduced into the holes, made for their reception, I apply a head of the
same metal, seen at Fig. 3, to each, on which is rivetted the projecting part
of the rivet, either with a hammer or by a single blow of the striker of suffi-
cient power. I may employ either of the above methods of fastening for all
kinds of military or other accoutrements, such as for railway companies'
equipments, belts, cartridge boxes, sword or bayonet scabbards or sheaths,
leggings, cases for military standards, and other similar purposes, either of
which methods ensures the same solidity and durability.
Having described the nature of this Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be protected
by the herein-before in part recited Letters Patent is, the new application of
screws or rivets for the entirely novel purposes described.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Eighth day of October, in the year of our Lord
One thousand eight hundred and sixty-two.
