PROVISIONAL SPECIFICATION.
Appliance for Stretching and Cupping the Leather of Boots for the
Relief of Corns and Bunions.
I, CHARLES JAMES ENGLAND, of 1, Clyde Park, Redland, Bristol, Gentleman, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an appliance whereby to enable the pressure of the boot
upon a corn or bunion to be relieved by the local stretching and cupping of the
leather at the part immediately covering the corn or bunion, the object being to
provide a tool capable of being easily manipulated by the wearer of the boot
whenever required.
The invention consists of a convex die and concave matrix adapted to produce
the cupped form desired and mounted at the extremities of the limbs of a rigid
U-shaped frame of such length as to admit of the introduction of the die within
the boot and the placing of the die within and of the matrix in exact opposition
thereto without the boot exactly in position corresponding to the point of pressure
to be relieved, the matrix being mounted on a screw spindle provided with a
handle for turning it, the spindle screwing through a corresponding socket in the
limb of the frame, so that when the die and matrix are placed in position within
and without the boot and are screwed up tightly together the leather and lining
of the boot will be pressed into such a concave convex form between the die anu
matrix that the direct pressure on the corn or bunion will be relieved and trans-
ferred to the surrounding healthy portion of the foot.
In order to facilitate the exact location of the die within the boot before screw-
ing up the matrix the die may be formed with a central projecting point whereby
to enable the location of the die to be ascertained by the sense of touch through
the leather of the boot.
The die and matrix are removably mounted on the frame and screw spindle
respectively, so as to enable them to be readily replaced by others of a shape suited
to the configuration and location of the part to be cupped, and the operation may
be repeated without injury to the leather as may be necessary to preserve the
cupped form, until by the long continued relief of pressure on the afflicted part
the corn dies away by natural action.
Appliance for Stretching and Cupping the Leather of Boots for the
Relief of Corns and Bunions.
I, CHARLES JAMES ENGLAND, formerly of 1, Clyde Park, and now of 101, Hamp-
ton Road, Redland, Bristol, Gentleman; 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:
-
My invention relates to an appliance whereby to enable the pressure of the
boot upon a corn or bunion to be relieved by the local stretching and cupping of
the leather of the boot upper at the part immediately covering the corn or bunion,
[Price 8d 1

page_text: the object being to provide a tool capable of being easily manipulated by the wearer
of the boot whenever required.
The accompanying drawing forming part of this specification shews a perspec-
tive view of the appliance forming the subject of my invention, in which a convex
die a and a concave or annular matrix adapted to produce the cupped form
desired are mounted opposite to one another at the extremities of the limbs of a
rigid U-shaped frame c of such length as to admit of the die a being placed within,
and the matrix b in exact opposition thereto, without the boot in position corre-
sponding to the point of pressure to be relieved wherever such point may be
situated. The matrix b. is mounted on a screw spindle a provided with a handle e
for turning it, the spindle d screwing through a corresponding socket in the limb
of the frame e so that when the die and matrix are placed in position respectively
within and without the boot and are screwed up tightly together by turning the
handle e, the leather and lining of the boot upper will be locally stretched and
brought to a concavo-convex form whereby, it will be raised from off the surface
of the foot at the required spot, thus relieving the corn or bunion of pressure.
In order to facilitate the exact location of the instrument before screwing up
the matrix, the die a may be formed with a central projecting point f whereby
to enable the location of the die to be ascertained by the sense of touch through
the leather of the boot, the required spot having been previously marked with
chalk outside the boot. The point also serves to prevent the instrument from
slipping whilst the screw is being turned.
The matrix h may be cup-shaped but is preferably annular as shewn so as to
afford a view of the spot to be cupped; the ring which is of a diameter to pass
over the dome-shaped die a, being connected to the screw spindle d by means of
a bridge-piece g spanning the ring. In either case the spindle d is shouldered
so as, when screwed up, to bear externally upon the cup or bridge-piece g, the
end of the spindle passing through and turning freely in a hole in the apex of the
cup or bridge-piece so that the matrix when in contact with the boot upper is not
caused to rotate with the spindle. A pin and washer h or equivalent device on
of the matrix when the
the end of the spindle ensures the retraction
the
direction and
the
spindle is rotated in
also permits of
matrix being removed when required. The die a is attached to the frame c by
means of the screw i so as to be easily removable, both die and matrix being
thus capable of being readily replaced by others of a shape suited to the configura-
tion and location of the part of the boot to be cupped or to the varying thickness
and flexibility of the leather and lining. The operation on the boot may be
repeated without injury to the leather as often as may be necessary to preserve the
cupped form, until by the continued relief of pressure on the part affected the corn
is permitted to die away by natural action.
reverse
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
An appliance for enabling the pressure of the boot on a corn or bunion to be
relieved, consisting of a convex die and a concave or annular matrix both mounted
on a frame whereby they may be applied respectively inside and outside the boot
in a position corresponding to that part of the boot upper to be acted on, and means
for pressing and clamping the boot upper between the die and matrix so as to
locally stretch and cup the leather, substantially as specified.
