Year: 1861

page_text: LETTERS PATENT to Pierre Emile Chassang, of No. 9, Rue du Conser-
vatoire, Paris, in the Empire of France, Banker, for the Invention of
"AN IMPROVED BUCKLE."-A communication from Simon Ghidiglia, a
Borson vocident at No 1 Rue des Fontaines Panic aforesaid
PROVISIONAL SPECIFICATION left by the said Pierre Emile Chassang
at the Office of the Commissioners of Patents, with his Petition, on the
8th January 1861.
I, PIERRE EMILE CHASSANG, of No. 9, Rue du Conservatoire, Paris, in the
Empire of France, Banker, do hereby declare the nature of the said Invention
for "AN IMPROVED BUCKLE," to be as follows:-
I construct a buckle plate with a slit or elongated hole at one end, to which
is attached one of the straps or bands, or one end of the strap or band, to be
united; at the back of the buckle plate is a moveable bar or frame hinged to
the buckle plate by two projections or otherwise. This bar enters a recess in
the buckle plate, which may be made by bending or stamping the same if of
sheet metal. The second strap or the loose end of the single strap is passed
from the back between the moveable bar and the buckle plate, and returned
upon itself; when this loose end is pulled, the pressure on the bar is slackened,
and the strap or straps may be drawn tighter together. On releasing the loose
end the strain on the tight part draws the bar into the recess, and so
compresses the strap and prevents it from slipping.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PIERRE
EMILE CHASSANG, of No. 9, Rue du Conservatoire, Paris, in the Empire of
France, Banker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of January, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Pierre Emile Chassang, Her special licence that I, the said Pierre.
Emile Chassang, my executors, administrators, and assigns, or such others
as I, the said Pierre Emile Chassang, 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 Inven-
tion for "AN IMPROVED BUCKLE," a communication from Simon Ghidiglia, a
person resident at No. 4, Rue des Fontaines, Paris, aforesaid, upon the
condition (amongst others) that I, the said Pierre Emile Chassang, 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 Pierre Emile Chassang, 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 accompanying Drawing,
that is to say:-
I construct a buckle plate with a slit or elongated hole at one end, to which
is attached one of the straps or bands, or one end of the strap or band to be
united; at the back of the buckle plate is a moveable bar or frame binged to
the buckle plate by two projections, or otherwise. This bar enters a recess in
the buckle plate, which may be made by bending or stamping the same if of
sheet metal. The second strap or the loose end of the single strap is passed
from the back between the moveable bar and the buckle plate and returned

page_text: upon itself; when this loose end is pulled, the pressure on the bar is slackened,
and the strap or straps may be drawn tighter together. On releasing the loose
end, the strain on the tight part draws the bar into the recess, and so con-
presses the strap and prevents it from slipping.
Figure 1 on the accompanying Drawing shews a front view of my improved
buckle; Figure 2 shews a back view of the same; Figure 3 shews a back
view of the buckle with the band or strap attached; Figure 4 shews an end
view of the same; and Figure 5 shews a detached view of the bar or frame.
The same letters indicate the same parts in all the Figures.
A is the buckle plate; a is the slit through which is passed the end of the
band or strap B, Figure 3, which is attached round the bar b; c, c, are small
projections on this bar which bite into the band B and prevent it from being
pushed together along the bar; d, d, are projections formed on or fixed in any
convenient manner to the buckle plate A and serving as pivots, upon which
hinges the moveable bar or frame C; e is a recess formed in the back of the
buckle plate, into which the moveable bar or frame C fits. The moveable bar
or frame C being raised to the position as indicated by dotted lines C',
Figure 4, the loose end of the strap or band B' is passed round the same, so as
to come between it and the back of the buckle plate. A strain on the strap
then causes the moveable bar or frame C to be pressed into the recess e,
whereby the loose end B¹ of the strap or band becomes nipped between the
moveable bar C and the buckle plate A, and is thus prevented from slipping.
By pulling the loose end B¹ of the strap, the moveable bar C is brought out of
the recess e, and the strap may be tightened.
Having now described the nature of my Invention, and in what manner
the same is to be performed, I wish it to be understood that I do not limit
myself to the exact contour of the buckle as shewn in the accompanying
Drawing, as this may be greatly varied without departing from the principle
of my Invention; but what I claim is, the improved construction of a buckle
for securing straps or bands as herein-before described.
In witness whereof, I, the said Pierre Emile Chassang, have hereunto
set my hand and seal, this Third day of July, in the year of our
Lord Oue thousand eight hundred and sixty-one.
PIERRE EMILE CHASSANG. (L.S.)
