IMPROVEMENTS IN BUSKS
Year: 1877

page_text: LETTERS PATENT to Jean Pascal J'Albert, of No. 19, Cours de Vincennes, Paris,
and Jean Felix Fénon, of No. 19, Cours de Vincennes, Paris, Busk Manu-
facturers, for the Invention of "IMPROVEMENTS IN BUSKS."
Sealed the 22nd January 1878, and dated the 7th August 1877.
PROVISIONAL SPECIFICATION left by the said Jean Pascal Jalbert and Jean
Felix Fénon at the Office of the Commissioners of Patents on the 7th August
1877.
JEAN PASCAL J'ALBERT, of No. 19, Cours de Vincennes, Paris, and JEAN FELIX
FENON, of No. 19, Cours de Vincennes, Paris, Busk Manufacturers. "IMPROVEMENTS
IN BUSKS."
Our Invention has reference to an improved mode of construction of metallic
busks for corsets, and consists in strengthening the main busk by a second super-
posed blade of same thickness, which is attached to the former at its upper extremity
by means of one or more rivets, and at its lower extremity by means of a slot and
pin, so that at this extremity one blade can slide on the other, whilst the two
remain constantly in contact, as well whilst they remain straight as when bent.

the said Jean Pascal Jalbert and Jean Felix Fénon in the Great Seal Patent
Office on the 6th February 1878.
JEAN PASCAL, JALBERT, of No. 19, Cours de Vincennes, Paris, and JEAN FELIX
FÉNON, of No. 19, Cours de Vincennes, Paris, Busk Manufacturers. "IMPROVEMENTS
IN BUSKS."
Our Invention has reference to an improved mode of construction of metallic
busks for corsets, and consists in strengthening the main busk by a second super-
posed blade of same thickness, which is attached to the former at its upper extremity
by means of one or more rivets, and at its lower extremity by means of a slot and
pin, so that at this extremity one blade can slide on the other whilst the two remain
constantly in contact, as well whilst they remain straight as when bent, and in this
manner the usual rupture of the leather, skin, or other material surrounding the busks
is avoided when said busk is bent.
And in order that our Invention may be properly understood and easily carried
into practice, we will describe it conjointly with the eight Figures of the accom-
panying Drawing, in which,-
Figure 1 is a front elevation of our improved busk; Figure 2, a side elevation of
the same; Figure 3, a back elevation, idem; Figure 4, a plan in section through A, A,
Figure 1.
Figure 5, a separate view of the connecting pin employed conjointly with the slide,
as shown in Figure 1.
Figure 6, a modification of Figure 1, which consists in substituting the pin shown
in Figure 8 to that shown in Figure 5; Figure 7, a plan in section of the above
modification through B, B, Figure 6; and Figure 8, a separate view of the connecting
pin shown in Figures 6 and 7.
In these Figures A, A, are the main blades forming the busk, and B, B, are the
secondary blades of about the same strength as A, A, united to the latter at their
upper ends by means of rivets C, C, or other suitable means, and at their lower
ends by means of slots and pins D, D, thus allowing the blades B, B, to slide
upon those A, A, and remain constantly in contact with the same when the busk is
bent.
Figure 6 shows a modification of Figure 1, which consists in substituting to the
long headed connecting pin D, shown in Figure 1, a round headed pin D¹, as shown
in Figures 7 and 8.
By this mode of construction we render both the blades A, A, and B, B, composing
our busks, completely unbreakable on account of the rivets being adapted at the
upper end only, and not in the middle and other places, as is generally the case in
these kinds of busks, and by the fact of the suppression of these rivets in the middle
of these blades, the secondary blades or busks B, B, follow exactly the curve which
the main blades A, A, describe when they are bent. The result of this arrangement
is that the two superposed blades are constantly maintained in contact with each
other, and the leather or other suitable material with which they are covered is not
susceptible of being deteriorated or split, with which defects the ordinary kind of
busks actually in use are justly reproached.
We claim as our Invention the construction of busks for stays or corsets of two
blades of metal or other appropriate substance superposed, being attached one to the
other at one point only, preferable at the top, with a connecting pin or bolt at
the bottom of one of these blades, sliding in a slot made in the corresponding
part of the other, in such a manner that upon bending, both blades follow exactly

page_text: the same course and remain nevertheless constantly in contact on their entire
surface.
In witness whereof, we, the said Jean Pascal Jalbert and Jean Felix Fénon,
have hereunto set our hands and seals, this Second day of February, in the
year of our Lord One thousand eight hundred and seventy-eight.
