IMPROVEMENT OR IMPROVEMENTS IN METALLIC STAY Buscs
Year: 1858

page_text: LETTERS PATENT to François Frédéric Delpy, of Paris, France, Jeweller,
for the Invention of "IMPROVEMENT OR IMPROVEMENTS IN METALLIC STAY
Buscs."
Sealed the 15th February 1859, and dated the 21st August 1858.
PROVISIONAL SPECIFICATION left by the said François Frédéric Delpy
at the Office of the Commissioners of Patents, with his Petition, on the
21st August 1858.
I, FRANÇOIS FRÉDÉRIC DELPY, of Paris, France, Jeweller, do hereby declare
the nature of the said Invention for "IMPROVEMENT OR IMPROVEMENTS IN
METALLIC STAY Buscs," to be as follows:-
The Invention relates to that kind of metallic stay buses, which being com-
posed of two pieces are made to hooke with one another by means of studs
riveted on one blade and eyes riveted on the other.
This kind of fastening being in some way inconvenient and subject to get
loose, I have substituted the contrivance shewn on the annexed Drawing.
On the blade A, I fix, by riveting, eyes provided with a little tongue o, which
enters in small eyes i, i, cut through the hooks D, D, riveted on the blade B,
when the two blades are put together.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANÇOIS
FRÉDÉRIC DELPY, of Paris, France, Jeweller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of August, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said François Frédéric Delpy, Her special licence that I,
the said François Frédéric Delpy, my executors, administrators, and assigns,
or such others as I, the said François Frédéric Delpy, my executors, adminis-
trators, 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 "IMPROVEMENT OR IMPROVEMENTS IN METALLIC STAY Buscs," upon
the condition (amongst others) that I, the said François Frédéric Delpy, 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 calen-
dar months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said François Frédéric Delpy, do hereby
declare the nature of my 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 Drawings hereunto annexed,
and to the letters and figures marked thereon, that is to say:-
Buses are commonly made of two steel blades, one of them having studs,
and the other eyes rivetted on them. There has hitherto been little alteration
in the shape, disposition, distance of the said studs and eyes, and they are made
sometimes of brass, iron, or other suitable metal, and are always found incon-
venient on account of the studs projecting too much, so that the dress is caught
or torn by them, or else they give way on account of the rivetting not being
solid enough; to repair them is tedious, as the blades are sewn up tightly in
the stays.
To remedy these defects I make the buscs without such rivetted pieces, or
else I give them a different disposition. The blades are punched out entirely

page_text: from steel sheets, and the shape which I give to the eyes and hooks causes
them to hold much more firmly, and moreover, they are hooked together more
easily, and the hooks protrude very little.
These improved stay buses are shewn in the annexed Drawing. Fig. 1
shows the two blades hooked together as when worm; the blade A, A, is
punched out with eyes C, C, having small studs projecting inside; and the
blade B, B, which is shewn edgeways, Fig. 2, is punched out in a similar
manner, with small projections d, d, which are bent so as to form a kind of
hook intended to enter the eyes C, C. The hooks d, d, are also perforated,
and the small studs i, i, enter the perforations, which keeps both blades fastened
together.
My buses are almost as solid as if they were made of a single piece, besides
which they can be very easily fastened and unfastened; they do not confine
the motions of the body, the garments are not liable to be torn, and lastly, they
can be made cheaper.
From this disposition of stay buses, entirely different from those in use, it is
evident that the same principle may be applied to make them with hooks and
eyes made fast to the blades by rivetting, as is shewn in the annexed Drawing,
Figs. 3 and 4; eyes C, C, with little inside studs are rivetted on one of the
blades, the small studs enter little perforations made through the hooks d, d,
which hooks are also fastened by rivetting on the blade B, shown edge-
ways, Fig. 4. The said eyes and hooks, which may be made of any suitable
metal, project but very little above the blades; by this mode of rivetting the
hooking pieces to the blades, the eyes C being placed above the junction of
both blades allows of their being brought closer together, which cannot be
done with the blades having the hooking pieces punched out.
This system might be used to fasten dresses, and I claim therefore as my im-
provements the making of buses, as herein described, or the principle thereof.
In witness whereof, I, the said François Frédéric Delpy, have hercunto
set my hand and seal, this Eighteenth day of February, in the year
of our Lord One thousand eight hundred and fifty-nine.
