PROVISIONAL SPECIFICATION.
Improvements relating to the Application of Socks or Insoles to
Boots and Shoes.
I, TIMOTHY GREEN DOUGLAS, Castle Mills, Fountainbridge, Edinburgh, India
Rubber Manufacturer, do hereby declare the nature of this invention to be as
follows:-
These improvements relate to the use of insoles made of thin cork or wood; they
are coated on one, the under, side with a strong cement by which to hold them
tightly to the boot or shoe thereby preventing the rapid deterioration and wear and
frequent discomfort experienced when they are put in loosely either alone or
combined with cloth by sewing and otherwise. Such insoles are peculiarly
suitable for india rubber shoes with cloth uppers the cork or wooden insoles
imparting a greater coolness than felt and such like insoles, and in the construction
of these and similar shoes or boots subjected to heat in the process, the india rubber
solution employed in making up such articles is peculiarly well suited for applying
to these cork or wood insoles as it is vulcanized along with the shoes or boots and
such insoles can be applied to or used in the construction of these articles in the
same way and as conveniently as insoles of leather felt or other materials. This
solution, a well known article with rubber manufacturers, may be conveniently
applied to such insoles by a brush, and although it is the most convenient cement
to employ, permitting such insoles to be applied while the boot or shoe is being
constructed any other sufficiently adhesive and flexible cement will answer the
purpose and if it be liable to injury by or during the process of construction of the
boot or shoe it may be used afterwards and either hot or cold according to its
composition and properties.

I, TIMOTHY GREEN DOUGLAS, of Castle Mills, Fountainbridge, Edinburgh,

what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A boot or shoe having an insole of cork or thin wood secured in its place by
cement.
2. In the manufacture of boots and shoes with india rubber soles and cork or
wood insoles, fixing the insole to the sole by means of india rubber cement and
afterwards exposing both together to heat by which vulcanization is effected.
