Year: 1853

page_text: LETTERS PATENT to Henry Blatin, of 30, Rue Bonaparte, Paris,
France, Gentleman, and 4, South Street, Finsbury, London, for
Sealed the 20th December 1853, and dated the 20th June 1853.
PROVISIONAL SPECIFICATION left by the said Henry Blatin at
the Office of the Commissioners of Patents, with his Petition,
on the 20th June 1853.
I, HENRY BLATIN, of 30, Rue Bonaparte, Paris, France, Gentleman,
and 4, South Street, Finsbury, London, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN BUCKLES" to be as follows:
My Invention consists in the peculiar arrangement of the tongue of
buckles, which I cause to turn back to facilitate its withdrawal from
the leather strap in which it is engaged.
The turning back of the tongue is effected by hinging it on a cranked
axle capable of moving in the frame of the buckle, and acted upon by
a small lever or arm fixed to it. A stud is fixed to keep the lever at
rest.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Blatin in the Great Seal Patent Office,
on the 20th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
HENRY BLATIN, of 30, Rue Bonaparte, Paris, France, Gentleman, and
4, South Street, Finsbury, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of June, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Blatin, Her special license
that I, the said Henry Blatin, my executors, administrators, and
assigns, or such others as I, the said Henry Blatin, 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 "IMPROVEMENTS IN
BUCKLES," upon the condition (amongst others) that I, the said
Henry Blatin, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, 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 Henry Blatin, 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 thereof, reference being had to the Drawing
hereto annexed, and to the figures and letters marked thereon, that
is to say:
My Invention consists in a new method of constructing buckles, by
which the strap is fastened and released without any effort upon the
strap itself.

page_text: The tongue of the buckle receives a movement of ascent or descent,
which causes it to engage or disengage the strap; these motions are
produced by a cranked axis A, forming the shoulder of the buckle
The extremities of the axis B, B', pass through the arms C, C, of the
buckle. A lever D, set on one end, gives motion to the axis A, and
to the crank E, on which the tongue is hinged. If the lever D, be
lowered from its stopping point G, it will compel the excentric to act
on the tongue, and force its point to recede from the notch H, on the
strap. This movement causes the tongue to release the strap with
facility, in spite of the strain exerted and the tension or thickness of
the strap.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I wish it to be understood
that I do not confine myself to the precise details of construction. But
what I claim is, the peculiar construction of buckles, by which the
tongue is made to fix and release the strap by means of a cranked axis
and lever, as herein-before described and referred to in reference to
the annexed Drawing.
In witness whereof, I, the said Henry Blatin, have hereunto set
my hand and seal, this Seventeenth day of December, One
thousand eight hundred and fifty-three.
Witness,
HY GILBEE.
H. BLATIN. (L.S.)
