Improvements in Revolving Plates or Pads for the Soles and Heels of
Boots and Shoes.
I GEORGE WOOD, of 4 Croft Street, Burnley, in the County of Lancaster,
Mining Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to make a false heel or heel pad of indiarubber,
leather, guttapercha, or combination of such substances which is affixed to the
ordinary heel of a boot or shoe, so as to prevent the original heel from becoming
worn down, and it is so affixed as described in the following specification, that it
can be revolved or turned round, so as to present a fresh portion of the pad for wear;
when the pad or false heel is partially worn.
In carrying out my invention, I make a disc of any suitable metal, for instance
brass or iron, and this metal disc is made of any size, so as to be adaptable for the
various sizes of the heels of boots and shoes. This metal disc has a hole in its
centre, and its face is punched or cut in the following unique manner that is
to say:-
-
I stamp, punch, or cut in the metal disc a number of slits preferably in the
shape of the letter V but may be of any suitable shape. The V pieces are not cut
directly from the plate but are held thereto by their third side, and are then struck
through the disc forming flat spikes or projections on the outer face of the metal
plate.
I now make or mould a piece of indiarubber, circular in shape, but with a much
larger hole in the centre than that in the metal disc before mentioned.
On the outer face of this indiarubber disc I make certain grooves or incisions
in shape to correspond with the projecting spikes, as previously described in the
metal disc.
I now take the rubber disc and place it on the projections of the metal plate,
these projections or spikes protruding through the incisions made in the rubber.
These spikes are now hammered down or clenched on to the rubber, and they
fill exactly the grooves shaped as above to receive them in the rubber, so that the
rubber stands proud of them, that is, the spikes are clenched down, so that they
are below the surface of the rubber disc. The rubber disc is now fastened to the
metal disc.
To affix the pad to the leather of the boot heel, I take a suitable spike, screw,
or nail. Placing the metal plate against the leather of the boot heel, I insert the
spike or nail in the centre hole of the metal disc and tighten it up.
The rubber thus presents itself for wear, and being ciroular in shape, when one
part of it has become worn on relaxing the centre screw or nail, it can be turned
round, to present another surface for wear.
The rubber may be fastened to the metal plate by bolts or studs, and the metal

page_text: plate although preferably circular in shape can be made in the shape of a cross or
any other form.
My invention is equally applicable to the soles as to the heels of boots and shoes.

Improvements in Revolving Plates or Pads for the Soles and Heels of
Boots and Shoes.
I GEORGE WOOD of 4, Croft Street, Burnley in the County of Lancaster,
Mining Engineer, do hereby declare the nature of my said 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 make a false heel or heel pad of indiarubber,
leather, guttapercha or combination of such substances which is affixed to the
ordinary heel of a boot or shoe, so as to prevent the original heel from becoming
worn down and it is so affixed as described in the following specification, so that it
can be revolved or turned round, so as to present a fresh portion of the pad for
wear; when the pad or false heel is partially worn.
In carrying out my invention, I make a disc of any suitable metal, for instance
brass or iron, and this metal disc is made of any size, so as to be adaptable for the
various sizes of the heels of boots and shoes. This metal disc has a hole in its
centre, and its face is punched or cut in the following unique manner, that is
to say:-
I stamp punch or cut in the metal disc a number of slits preferably in the shape
of the letter V, but may be of any suitable shape. The V pieces are not cut
directly from the plate but are held thereto by their third side, and are then struck
through the disc forming flat spikes or projections on the outer face of the metal
piate.
I now make or mould a piece of indiarubber, circular in shape but with a much
larger hole in the centre than that in the metal disc before mentioned.
On the outer face of this indiarubber disc, I make certain grooves or incisions
in shape to correspond with the projecting spikes, as previously described in the
metal disc.
I now take the rubber disc and place it on the projections of the metal plate,
these projections or spikes protruding through the incisions made in the rubber.
These spikes are now hammered down or clenched onto the rubber, and they
fill exactly the grooves shaped as above to receive them in the rubber, so that the
rubber stands proud of them, that is, the spikes are clenched down, so that they
are below the surface of the rubber disc. The rubber disc is now fastened to the
metal disc.
To affix the pad to the leather of the boot heel, I take a suitable spike, screw or
sil. Placing the metal plate against the leather of the boot heel, I insert the
spike or nail in the centre hole of the metal disc and tighten it up.
The rubber thus presents itself for wear, and being circulat in shape, when one
part of it has become worn on relaxing the central screw or nail, it can be turned
round to present another surface for wear.
The rubber may be fastened to the metal plate by bolts or studs, and the metal
plate although preferably circular in shape can be made in the shape of a cross or
any other form.

page_text: My invention is equally applicable to the soles as to the heels of boots and shoes.
For the purpose of illustrating my invention, I have hereunto attached the
accompanying drawings:-
Fig. 1 is a plan of the metal plate, or disc, and Fig. 2 an elevation of the same.
A is the central hole, by which the metal disc is fixed to the boot heel. BB BB are
the V or other suitably formed slits made in the disc. The V shaped pieces are
not cut directly from the plate, but are held by their third side, which is left
intact, and are struck through the disc forming flat spikes or projections on the
outer face of the metal plate. This will be readily understood by reference to
Fig. 2, in which CCC are the V shaped pieces, which are struck up after the
slitting of the metal plate has been effected.
I now take or mould a pad or piece of indiarubber or some such substance D,
shewn in Fig. 3, and with a larger central hole than that in the metal disc above
described. This rubber pad is formed or pierced with certain slits E, and under-
sunk grooves or incisions F to correspond with the projecting spikes as previously
described in the metal disc. The spikes C are pushed through the slits E in the
rubber pad, and are then clenched down in the undersunk grooves or incisions F,
so that they are below the surface of the rubber disc.
Fig. 4 will clearly illustrate this part of my invention, and the means of attach-
ment to the boot heel.
The spikes C are clamped down in the undersunk grooves F, so as to come below
the surface of the rubber pad. The screw, nail or spike G secures the metal plate
to the boot heel, by its central hole A. When a portion of the pad becomes worn,
a fresh surface may be presented for wear, either by untightening the screw G,
and revolving the rubber pad, or leaving the latter sufficiently slack to permit the
pad to revolve with the motion of the foot in walking.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The improved arrangement and construction of revolving heel plates or pads
for the soles and heels of boots and shoes, substantially as shewn and described.
2. The method of securing the rubber pad to the metal plate, substantially as
shewn and described.
Dated this 19th day of August 1897.
