PROVISIONAL SPECIFICATION.
Improvements in and connected with the Manufacture and Repairing
of Coverings for the Feet.
I, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of
Chester, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the production of a cement and method of using the
same in the manufacture or repairing of coverings for the feet.
The said cement I form by dissolving pure rubber and gutta-percha in about
equal proportions separately by adding thereto a small quantity of bi-sulphide of
carbon which will be absorbed by the said rubber and gutta-percha and then
liquifying each to its desired consistency by adding thereto spirits of petroleum
benzoine or naphtha. To the said mixture I may also add a small quantity of
gum-mastic or gum-copal mixed with rosin. The ingredients described are then
all mixed together and a small quantity of sulphur and red lead or litharge added.
The cement thus formed drys very quickly and is adapted for uniting together
the various parts of coverings for the feet in the manufacture or the repairing.
For lasting and some other purposes connected with the manufacture and the
repairing of coverings for the feet I may dispense with the said gutta-percha
solution and red lead or litharge and mix with the rubber solution in equal pro-
portions gum rosin dissolved in spirits of petroleum or benzoine which mixture
forms a cement which sets slowly, remains sticky or tacky for a long time and is
thus specially adapted for lasting purposes.
Either of the cements described, preferably the former, may also be used to form
puffs" for the toes of the covering and in lieu of side linings, by covering suitably
shaped pieces of fabric therewith.
In lasting coverings for the feet the cement is applied around the edge of the
insole by means of a brush and when using a stiff upper also around its edge.
After the upper has been pulled over either by hand or machine the said cement
unites the insole and upper quickly and securely together, thus dispensing with
tacks. The outer sole is then secured to the upper by roughening the underside
of the sole and the upper around the edge, then coating it thickly with the said
cement and allowing each coating to partly dry. The two coated parts are then
heated and pressed together whilst being hot, which causes the cement thereon te
partly vulcanize and thus unite the said parts securely together.
In the manufacture of boots or shoes in which the edge of the upper is turned
outwards and secured upon the sole I coat the under-side of the turned out part
of the upper with the cement described, preferably the former, before stitching it
to the sole which thoroughly unites the same together and prevents the edge of the
upper curling up in wear.
In the manufacture of Lawn-tennis and the like boots and shoes I form the
raised or channelled wearing surface, by using leather as a sole and blocking the

page_text: same between male and female dies shaped to produce the desired form of raised
surface.
The cavities or depressions thus formed in the underside of the sole I fill up with
gutta-percha which serves to retain the said raised surface in shape, after which
I unite the sole with the upper with the cement and in the manner as hereinbefore 5
described.

Improvements in and connected with the Manufacture and Repairing
of Coverings for the Feet.
I, THOMAS GARE, of 25, Booth Street, Edgeley, Stockport, in the County of
Chester, Engineer, 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:-
This invention relates to the production of a cement and method of using the
same in the manufacture or repairing of coverings for the feet.
In carrying out my invention I form the said cement by semi-dissolving pure
rubber and gutta-percha in about equal proportions separately, by adding thereto
a small quantity of bi-sulphide of carbon which will be absorbed by the said rubber
and gutta-percha and then liquifying each to its desired consistency by adding
thereto spirits of petroleum, benzoine or naphtha. To the said mixture I may
also add a small quantity of gum-mastic, or gum-copal mixed with rosin. The
ingredients described are then all mixed together and a small quantity of sulphur
and red lead, or litharge may be added. The cement thus formed drys very quickly
and is adapted for uniting together the various parts of coverings for the feet in
the manufacture or the repairing.
For lasting and some other purposes connected with the manufacture and the
repairing of coverings for the feet I may dispense with the said gutta-percha solu-
tion and red lead or litharge and mix with the rubber solution in equal proportions
gum rosin dissolved in spirits of petroleum, benzoine or naphtha which mixture
forms a cement which sets slowly, remains sticky or tacky for a long time and is
thus specially adapted for lasting purposes.
Either of the cements described, preferably the former, may also be used to form
"puffs" for the toes of the covering and in lieu of side linings, by covering suitably
shaped pieces of fabric therewith.
In lasting coverings for the feet the cement is applied around the edge of the
insole by means of a brush and when using a stiff upper also around its edge.
After the upper has been pulled over either by hand or machine the said cement
unites the insole and upper quickly and securely together, thus dispensing with
tacks. The outer sole is then secured to the upper by roughening the underside
of the sole and the upper round the edge, then coating it thickly with the said
cement and allowing each coating to partly dry. The two coated parts are then
heated and pressed together whilst being hot, which causes the cement thereon
to partly vulcanize and thus unite the said parts securely together.
In the manufacture of boots or shoes, such as "Veldt schoens," in which the
edge of the upper is turned outwards and secured upon the sole, I coat the under-
side of the turned out part of the upper with one of the cements described,

page_text: preferably the former, before stitching it to the sole, which thoroughly unites the
same together and prevents the edge of the upper curling up in wear.
In the manufacture of Lawn-tennis and the like boots and shoes I form the
raised or channelled wearing surface, by using leather as a sole and blocking the
same between male and female dies shaped to produce the desired form of raised
surface.
The cavities or depressions thus formed in the inner side of the sole after having
been coated with any of the described cements, I fill up with gutta-percha which
serves to retain the said raised surface in shape, after which I unite the sole with
the upper with the cement and in the manner as hereinbefore described.
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 "In or connected with the manufacture and repairing of coverings for
the feet":-
1st. A cement having for its basis pure rubber, sulphur and gum rosin, the said
rubber being semi-dissolved by bi-sulphide of carbon and said rubber and gum
rosin liquified to the desired consistency by spirits of petroleum, benzoine or
naphtha, all substantially as set forth.
2nd. In a cement having for its basis the ingredients specified in the preceding
claim, the addition of gutta-percha and red lead, or litharge, the said gutta-percha
being semi-dissolved by bi-sulphide of carbon and the mixture liquified by
petroleum, benzoine or naphtha, all substantially as set forth.
3rd. In a cement having for its basis the ingredients specified in the preceding
claim, the addition of gum-mastic, or gum-copal with rosin, all substantially as
set forth.
4th. The use of the cement, specified in the preceding claims, for coating suitably
shaped pieces of fabric adapted to form "puffs" or side pieces for coverings for the
feet, all substantially as set forth.
5th. The blocking of leather soles by means of male and female dies to produce
a raised surface and filling up the cavities with gutta-percha, all substantially as
set forth.
6th. The method of using the cement, specified in Claims 1, 2 & 3, substantially
as and for the manner hereinbefore set forth.
