PROVISIONAL SPECIFICATION.
Improvements in Corset Stiffeners and Busks.
I, AUGUST BÜNGER, of Wilhelmsthal, near Lennep in the German Empire
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in corset stiffeners or busks especially in
the closing stiffeners and it has for its object to provide such stiffeners with means
which make them infrangible but allow them to be exceedingly clastical, so that
the danger of wounding a lady by a damaged stiffener is perfectly avoided; and
my invention consists in the features and details hereinafter described.
The mauner in which I carry my invention into effect is shown on the
accompanying drawing on which:
Figure 1 is a front elevation of the closing stiffeners ;
Figure 2 a vertical section through one of the same;
Figure 3 a back view from Figure 1.
In making my invention or improvements in corset closing stiffeners I make the
stiffeners A and B either in the spoon form shown in the drawings or in any other
suitable form with pins c and loops d by which one stiffener engages the other.
Now a little below the middle I provide cach blank with two plate springs e which
I fix to the same by rivetting them at their contrary ends to the blanks whilst the
other ends are left free. The springs come thus to lay upon each other, they are
guided by an ear for other suitable means which allow the motion of the springs
upon each other when the stiffener is bent. The springs being made of best steel
cause that the closing stiffeners which are made as well known also of steel always
come back in their former position after being bent so that no damaging of them
can take place, because the pressure being else taken up by the stiffener alone is
now distributed to the stiffener aud the two springs each of them has therefore
to persist a pressure of one third only. The springs may be attached either
directly to the stiffener or they may be fixed upon the stuff with which the stiffeners
are fitted.

I AUGUST BÜNGER of Wilhelmsthal near Lennep, in the German Empire,
Manufacturer do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:--
This invention relates to an improvement in the manner of applying or arranging

page_text: auxiliary springs to corset stiffeners and busks and consists in combining, with the
busk two plates or flat springs, the one end of which being rivetted or otherwise
fastened to the busk so that said springs lay upon each other being guided in this
position by an ear or loop or other suitable means which allows the two auxiliary
springs to play on the said busk.
In order to a clear understanding of my invention, as well as to enable others,
skilled in this art of manufacture, to make and use the same, I will proceed to
give a full description thereof, as illustrated in the drawings, filed with my
Provisional Specification, of which:
Figure 1 is a front elevation of the busk;
Figure 2 a vertical section through one of the same;
Figure 3 a back view from Figure 1.
In making my invention or improvements in corset closing stiffeners or busks
I make the busks A and B either in the spoon form shown in the drawings or in
any other suitable form. Such busks are provided with connection means
consisting of pins e and loops d by which one busk engages the other.
с
e are the two auxiliary springs applied to each stiffener. They are made from
sheet steel or other suitable material, and punched at one end, so as to be rivetted
to the principal steel or busk A and B respectively, which as may be best seen
from Figure 1 carry the auxiliary springs from behind.
i
As the said springs are nearly of same length, they are so arranged that one
spring takes position on the other and lap the same nearly on its whole length, it
may thus play on his companion or together with the same on the principal steel,
when the latter is bent.
To prevent a play of said springs sideways they are guided by an ear for other
suitable means which are fastened to the main busk.
The most excellent effect which is gained by my invention is that the steel is
strengthened at the point where it is most exposed to break. The steel gains by
the two auxiliary springs an increased elasticity which aids materially in retaining
it in proper form. It will be less charged because the pressure being else taken
up by the steel alone is now distributed to the stiffener and the two auxiliary
springs, each of these three parts has therefore to persist a pressure of one third
only.
The springs may be affixed to the busk either directly on the metal or upon the
stuff with which the stiffener are fitted.
Having now particularly described the nature of my said invention and in what
manner the same is to be performed, I declare that what I claim is:
In corset stiffeners or busks, combining with each principal spring, two
auxiliary springs (e) the extreme end of each rigidly secured to the principal
spring, the other end of the said auxiliary springs lap each other nearly their
whole length, the springs being guided in this position on the principal busk by
an ear (or other suitable means for the purpose as set forth and hereinbefore
described.
