IMPROVEMENTS IN THE MANUFACTURE OF HEELS FOR BOOTS AND SHOES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We JOHN WARD JONES of 78 Ambler Road Finsbury Park in the County of
Middlesex Boot and Shoe Manufacturer and EDWARD KYNASTON BRIDGER of 37
King William Street in the City of London Solicitor do hereby declare the nature
of our Invention for "IMPROVEMENTS IN THE MANUFACTURE OF HEELS FOR BOOTS
AND SHOES" to be as follows:-
This Invention relates first to the manufacture of hollow metal heels of suitable
shape for boots and shoes from blanks of sheet iron or other metal by sinking such
metal blanks in dies of suitable form and shape by pressure in suitable presses or
by stamps as is well understood in the operation of sinking or stamping metal
blanks for other purposes. The male and female dies employed for the finishing
operation correspond in form with that of the hollow metal heel required and such
hollow metal heels have bottom plates or wearing surfaces applied or affixed thereto
in any suitable manner.
According to another part of our improvements hollow metal heels of suitable
shape for boots and shoes are made from solid blanks of iron or other comparatively
soft metal by a process or operation known as "spinning" employed in the
manufacture of metal capsules.
For our purpose a blank of suitable metal is placed in a comparatively shallow
die of the form or shape of the hollow heel to be made therein but as much larger
as the thickness of the metal walls forming the metal heel. A male die corte-
sponding in form with the interior of the metal heel is then brought down upon
the metal blank and sufficient pressure is then exerted upon it to force the metal
up the space between the inner sides or surface of the female die and the outer
edges of the blank and thus cause the metal to rise up around the outer surface of
the male die and thus form the hollow metal heel which can then be completed and
finished by having a bottom plate or wearing surface applied thereto as is well
understood in the manufacture of hollow metal heels for boots and shoes.
Another part of our improvements in the manufacture of hollow heels consists
in forming or moulding them from any suitable composition or material which
(when moulded in dies corresponding in form or shape with the hollow heel
required) will set and become sufficiently hard for being applied to a boot or shoe
...

page_text: to serve as a heel thereto which may be used either with or without a bottom plate
or wearing surface.
We are acquainted with several compositions or materials suitable for the above
purpose but we find it advantageous to employ a composition such as or similar to
that described in the Specifications of Letters Patent granted to E. C. T. Blake
dated 22nd December 1880 N° 5380 and 23rd June 1883 N° 3127 and we wish it
to be clearly understood that we make no claim to these or any other compositions
for this purpose.

King William Street in the City of London, Solicitor do hereby declare the nature
of our Invention for "IMPROVEMENTS IN THE MANUFACTURE OF HEELS FOR BOOTS

described and ascertained in and by the following statement:-

This Invention relates first to the manufacture of hollow metal heels of suitable
shape for boots and shoes from blanks of sheet iron or other metal by sinking
such metal blanks in dies of suitable form and shape by pressure in suitable presses
or by stamps as is well understood in the operation of sinking or stamping metal
blanks for other purposes. The male and female dies employed for the finishing
operation correspond in form with that of the hollow metal heel required and such
hollow metal heels have bottom plates or wearing surfaces applied or affixed thereto
in any suitable manner.
Figure 1 of the Drawings hereto annexed is a diagram showing how a piece of
sheet metal is brought by a series of successive sinkings in suitable dies to the
shape of the metal heel required and Figure 2 is a plan of a metal heel when sunk
to the proper shape in accordance with this part of our improvements.
According to another part of our improvements hollow metal heels of suitable
shape for boots and shoes are made from solid blanks of iron or other comparatively
soft metal by a process or operation known as "spinning" employed in the
manufacture of metal capsules.
For our purpose a blank of suitable metal is placed in a comparatively shallow
die of the form or shape of the hollow heel to be made therein but as much larger
as the thickness of the metal walls forming the metal heel.
A male die corresponding in form with the interior of the metal heel is then
brought down upon the metal blank and sufficient pressure is then exerted upon it
to force the metal up the space between the inner sides or surface of the female die
and the outer edges of the blank and thus cause the metal to rise up around the
outer surface of the male die and thus form the hollow metal heel which can then
be completed and finished by having a bottom plate or wearing surface applied
thereto.
Another part of our improvements in the manufacture of hollow heels consists
in forming or moulding them from any suitable composition or material which
(when moulded in dies corresponding in form or shape with the hollow heel
required) will set and become sufficiently hard for being applied to a boot or shoe
to serve as a heel thereto which may be used either with or without a bottom plate
or wearing surface.
We are acquainted with several compositions or materials suitable for the above
purpose but we find it advantageous to employ a composition such as or similar to
that described in the Specifications of Letters Patent granted to E. C. T. Blake
dated 22nd December 1880 N° 5380 and 23rd June 1883 N° 3127 and we wish it
to be clearly understood that we make no claim to these or any other compositions
for this purpose as we do not intend to limit ourselves thereto.
In carrying out this part of our improvements for forming composition heels in
accordance with our Invention we use a die and shank of special construction and
an ordinary screw or lever press as represented in Figure 3 of the Drawing which
shows a sectional view of the die and shank. A is the die which may be made of

page_text: cast iron or other suitable material this is shaped to the form of the heel and the
top part is carried up parallel. B is the shank. When a semi liquid material is
used we sometimes make the die hollow as shown with perforations to allow of the
liquid being pressed out.
The bottom of the shank is shaped to the interior of the heel and the shank is
continued up parallel to fit the die so that the composition cannot escape.
Figure 4 is a plan view of the die Figure 5 a plan of the shank Figure 6 a front
view of the shank and Figure 7 a section of pressed heel.
Having now particularly described and ascertained the nature of our Invention
and in what manner the same is to be performed we declare that what we
claim is :-
First. The improved manufacture of metal heels for boots and shoes by sinking
or stamping sheet metal in dies to the desired form substantially as hereinbefore
described and illustrated.
Second. The improved manufacture of metal heels for boots and shoes by the
operation of "spinning" by suitable dies substantially as hereinbefore described.
Third. The improved manufacture of heels for boots and shoes by forming or
moulding them in suitable dies from composition or material which will set hard
after being moulded substantially as described with reference to Figures 3, 4, 5, 6
and 7 of the Drawings hereto annexed.
