Improvements in Busks for Stays and Corsets.
I JOHN JENKIN CLARKE of the firm of J. J. Clarke Son and Company of Nos. 93
and 94 Broad Street Birmingham in the County of Warwick Manufacturers do hereby
declare the naturo of this Invention to be as follows:-
-
My invention has reference principally to three fold busks for stays and corsets
that is busks composed of three thin superposed pieces of steel the inner pieces of
steel being of less length and of the same or less with than the principal or outer
busk. The use of the inner pieces of steel is to strengthen the outer or principal busk
and to prevent the overbending or breaking of the latter. The thin inner pieces of
steel are capable of a slight sliding longitudinal motion to accomodate them to the
change of figure of the busk.
I make the principal or front part of the three fold busk in the ordinary way and I
connect the sliding piece of steel working on its inner face in the ordinary way that
is the broad part of the second busk or piece of steel is riveted to the broad part of
the principal or outer busk but the narrow end of the inner busk is not connected
rigidly to the outer busk but is connected by a neck or contraction working in a loop
closed upon the outer part of the busk so that the former may have a slight longi-
tudinal motion on the latter. The second inner sliding part of the busk is riveted to
the broad end of the first sliding part. The said second sliding part is of less length
than the first sliding part and its free end is made into a tongue that is the metal is
reduced in width at that end and shoulders formed on either side of it where it joins
the busk. The said tongue is situated in the same plane as the piece from which it
is cut and the shoulders form stops. In the first sliding part of the busk a slit or
incision is made of a size suitable for the tongue on the second sliding part to pass
through and work in. By inserting the tongue on the narrow end of the second
sliding part of the busk through the slit or incision in the first sliding part the
greater part of the said tongue passes between the first sliding part and the outer or
principal part of the busk and bears on the said outer part. The said tongue permits
the second sliding part to have a slight longitudinal movement upon the first sliding
part without being disconnected from it the shoulders at the base of the tongue
acting as stops and limiting the motion in one direction of the second sliding part
upon the first sliding part. A three fold busk thus produced the two inner folds or
parts of the busk being capable of sliding as the busk changes its figure.
The tongue and slit arrangement for securing the second sliding part of the busk
to the first sliding part of a three fold busk may also be applied to the securing of
the first sliding part to the outer or principal part of the busk and also in a two
fold busk for securing the inner sliding part to the onter or principal part of
the busk.

Improvements in Busks for Stays and Corsets.
I JOHN JENKIN CLARKE of the firm of J. J. Clarke Son and Company of No. 93
and 94 Broad Street Birmingham in the County of Warwick Manufacturers do
hereby declare the nature of my invention and the manner in which the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My invention has reference principally to three fold busks for stays and corsets,

page_text: that is, busks composed of three thin superposed pieces of steel the inner pieces of
steel being of less length and of the same or less width than the principal or outer
Lusk. The use of the inner pieces of steel is to strengthen the outer or principal
busk and to prevent the overbending or breaking of the latter. The thin inner
pieces of steel are capable of' a slight sliding longitudinal motion, to accommodate
them to the change of figure of the busk.
I make the principal or front part of the three fold busk in the ordinary way and
I connect the sliding piece of steel working on its inner face in the ordinary way:
that is the broad part of the second busk or piece of steel is riveted to the broad
part of the principal or outer busk but the narrow end of the inner busk is not
connected rigidly to the outer busk but is connected by a neck or contraction
working in a loop closed upon the outer part of the busk so that the former may
have a slight longitudinal motion on the latter. The second inner sliding part of
the busk is riveted to the broad end of the first sliding part. The said second
sliding part is of less length than the first sliding part and its free end is made into
a tongue: that is, the metal is reduced in width at that end and shoulders formed
on either side of it where it joins the busk. The said tongue is situated in the
same plane as the piece from which it is cut and the shoulders form. stops. In
the first sliding part of the busk a slit or incision is made of a size suitable for the
tongue on the second sliding part to pass through and work in. By inserting the
tongue on the narrow end of the second sliding part of the busk through the slit or
incision in the first sliding part the greater part of the said tongue passes between
the first sliding part and the outer or principal part and bears on the said outer
part. The said tongue permits the second sliding part to have a slight longitudinal
movement upon the first sliding part without being disconnected from it, the shoulders
at the base of the tongue acting as stops and limiting the motion in one direction of
the second sliding part upon the first sliding part. A three fold busk is thus produced
the two inner folds or parts of the busk being capable of sliding as the busk changes
its figure.
The tongue and slit arrangement for securing the second sliding part of the busk
to the first sliding part of a three fold busk may also be applied to the securing
of the first sliding part to the outer or principal part of the busk and also in a two
fold busk for securing the inner sliding part to the outer or principal part of
the busk.
Figure 1 of the accompanying Drawings represents in back elevations and
Figure 2 in edge view a three fold busk for stays and corsets made according to
my invention Figure 3 represents a portion of the same drawn to a larger scale.
a is the principal or front part of the busk; b is the first sliding part situated on
the inner face of the part a and c is the second sliding part situated on the inner face
of the part b. The first sliding part is connected at its broad end to the principal
part a by the rivet at d and the narrow end of the said sliding part bis connected to
the principal part a by a neck e working in a loop upon the back of the part.a.
By this means the sliding part is capable of a slight longitudinal movement on the
part a. The second sliding part c is riveted to the first sliding part by the rivet d
and the free end of the second sliding part c is made into a tongue g which is passed
through a slit or incision in a shoulder i made in the first sliding part b. When.
the tongue g of the second sliding part c is passed through the slit h in the first
sliding part b, the said tongue for the most part is situated between the first sliding
part band the outer part a. The said tongue g permits the second sliding part e to
have a slight longitudinal movement upon the other sliding part 6 without being
disconnected from it the shoulders kk at the base of the tongue g acting as stops
and limiting the motion in one direction of the sliding part e upon the sliding
part b.
b
By the arrangement or combination of parts described and represented the inner
folds or parts bc of the three fold busk are capable of sliding as the busk changes its
figure when in use.
Figure 1 represents the tongue and slit arrangement applied to a two fold busk a

page_text: is
being the principal or outer part of the busk and 6 the sliding part on its back;
the tongue on the sliding part 6 passed' through a slit hat the shoulder on the
principal part a so as to permit of the longitudinal movement of the part b on the
part a as the busk changes its figure.
Figure 5 represents the tongue and slit arrangement applied to a three fold busk.
The three parts of the busk are marked respectively a b and c; g² is the tongue of the
first sliding part b passed through a slit in the principal or outer part a and g³ is
the tongue of the second sliding part c passed through a slit h³, in the first sliding
part b. The two sliding parts b, c are thus made capable of a slight longitudinal
movement as the busk changes its figure without being disconnected from the
respective parts to which they are secured.
Figure 6 represents in back elevation an edge view and Figure 7 a portion of the
same drawn to a larger scale, a modified three fold busk made according to my
invention. In this modification the first sliding part 6 is riveted to the principal or
outer part a at d but its upper end is free and is capable of longitudinal movement
between the outer part a and the second sliding part c.
The second sliding part c is
in this modification riveted at d to the two parts a and b but its upper end is
connected to the outer part a by the neck e working in the loop f on the back of
the outer part a.
Or in place of the connection for the part c represented in the
Drawing the tongue and slit arrangement herein before described and represented may
be employed.
Any of the ordinary or other fastenings may be used with busks made according
to my invention.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in busks for stays and corsets" :-
First-Connecting the second sliding part of a three fold steel busk to the first
sliding part by the tongue and slit arrangement herein before described and represented
in Figures 1, 2 and 3 of the accompanying Drawings.
Secondly-Connecting the back sliding part of a two fold steel busk to the front
or principal part by the tongue and slit arrangement herein before described and
represented in Figure 4 of the accompanying Drawings.
Thirdly-Connecting the first sliding part of a three fold steel busk to the
principal or front part and the second sliding part to the first sliding part by the
tongue and slit arrangements herein before described and represented in Figure 5 of
the accompanying Drawings.
Lastly: The arrangement of the parts of a three fold steel busk in which the free
end of the first sliding part is unconnected with the other parts and is situated and
has a slight longitudinal movement between the front or principal part and the
second sliding part the latter being so connected to the front or principal part that it
is capable of sliding thereon as herein before described and illustrated in Figures 6
and 7 of the accompanying Drawings.
