Improvements in the Manufacture of India-rubber Socks for Boots
and Shoes.
I, JAMES STANSFIELD, of Wellington Terrace, Todmorden, in the County of
York, Asphalte Manufacturer, do hereby declare the nature of this invention to
be as follows:-
It relates to socks, or insoles, of boots and shoes, which are made with spaces and
perforations between the bottom of the insole and the boot for the free circulation
of air, and has for its object the more ready and cheaper making of the same.
To accomplish this, I use three metal plates, one of which is provided with a
suitable mould, or matrix, on each of its sides, for forming the lower side of a sock
or insole. The rubber is placed upon each side of this plate in a soft state, and the
two plain plates placed over the rubber upon each side, and compressed together
by screns or other suitable devices, so as to force the rubber into the moulds.
The socks or insoles are then vulcanized, and covered with cloth or other suitable
material in the usual manner.
Dated this 18th day of May 1895.

Improvements in the Manufacture of India-rubber Socks for Boots
and Shoes.
I, JAMES STANSFIELD, of Wellington Terrace, Todmorden, in the County of
York, Asphalte Manufacturer, 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:-
It relates to socks or insoles of boots and shoes, which are made with spaces
and perforations between the bottom of the insole and the boot for the free
circulation of air, and has for its object the more ready and cheaper making of the
same.
I accomplish this by using three metal plates, one of which is provided with a
suitable mould or matrix for forming the lower side of a sock or insole on each of
its sides.
These moulds or matrixes are fitted with a suitable spike or punch wherever it
is desired to make a perforation in the sock.
The rubber is placed upon each side of this plate in a soft state and two metal
plain plates (which are suitably perforated to allow the passage of the spikes or
punches) placed over the rubber on each side and compressed together by
screws or other suitable devices so as to force the rubber into the moulds.
The socks or insoles are then vulcanized and covered with cloth or other suitable
material in the usual manner.

page_text: Referring to the drawings sent berewith,
Fig. 1 is a longitudinal section of the three plates described and Fig. 2 a plan of
one side of the central plate.
In these figs. a indicates the central plate, upon which are spikes or punches b
which pass into corresponding holes in plain plates c and d. The three plates are
accurately placed together by means of guide pins e e.
Fig. 3 shows a longitudinal section of a pair of plates, consisting of a plate f with
a mould or matrix on one side only and one plain plate 9. These find convenient
for use when steam chests are used in the vulcanizing process. They are also
fitted with spikes or punches as shown in the treble plate and are shown in the
drawing with the rubber sock h compressed between them.
The spikes or punches b may in some cases be attached to the plain plates c, d or g
and holes perforated in the mould a or if more convenient.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is:
--
The combined apparatus, substantially as described and shown hereinbefore and
in the accompanying drawing, for the purpose set forth.
