PROVISIONAL SPECIFICATION.
Improvements in Stay Busks.
JAMES BRACKENBURY DAVIS 147 Stockwell Park Road Brixton London S.W.
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to render the busks of corsets or stays unbreakable,
whilst retaining perfect elasticity and pliability.
The invention consists of the application of springs made of layers of the best
steel, to the front of the busk only at the bend or waist. The springs are pivotted
in the centre in such a manner as to allow free play or action so that when busk is
bent or doubled, the pressure is taken up by the springs, which give strength at the
required point & prevent fracture.
The springs applied in this method do not act upon the whole length of the busk,
but only at the centre where the bending occurs, & there is no undue stiffness or
pressure upon the top of busk, and no appreciable increase in weight or thickness.
After bending the busk always regains its natural shape.
Dated this 28th day of May 1894.

London S.W. Mechanical Engineer 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:-
The object of my invention is to render the busks of corsets unbreakable, to
cause them to keep their proper shape and to increase theirʻpliability, without
adding appreciably to the weight or thickness.
In carrying out my invention I apply to the front of the busks at the waist, a
series of two or more thin plates of the best tempered steel in graduated lengths
and widths, pivotted at the centre-thus forming a perfect spring which acts in such
a manner that when outward bending takes place the spring comes into play &
prevents any acute bending or fracture of the busks. It also causes the busk after
bending to return to its original shape.
By applying my springs at the waist only the busks are not stiffened throughout
the whole length-that part only being acted upon where fracture is liable to
occur, thus leaving perfect pliability & elasticity and in fact increasing the same.
In order that my invention may be better understood I will proceed to explain
the same in connection with the accompanying sheet of drawings in which
Fig. 1 represents the springs as applied to the front at the waist of busk.
Fig. 2 represents side view of busks with springs in section.
These illustrate the springs applied to spoon shaped busks but I apply my
method also to straight or parallel busks of any kind.

page_text: Having now particularly described & ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what I
claim is:
The application of steel springs to the part of busks where bending or fracture
occurs in such a manner as to prevent breaking, preserve the shape, & give
increased flexibility without adding appreciably to weight or thickness.
