PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Rubber Soled Foot Wear.
I, CHARLES LEANDER HIGGINS, of No. 178 Inspector Street, in the City of
Montreal, in the District of Montreal and Province of Quebec, Dominion of
Canada, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of foot wear having an upper of leather, felt
or other textile material, and a rubber sole portion; the object being to secure a
stronger and more permanent connection between the sole and the upper, as well as
to render same less liable to leakage.
The invention consists in the method of attaching the rubber sole to the upper,
and in the construction of the complete article.
To the unlasted vamp or upper of any foot covering such as a boot or shoe
whether of leather, felt or other textile fabric I attach, preferably by stitching in a
zig-zag fashion a connecting strip preferably of which is known to rubber foot
wear manufacturers' as "frictioned stock" the strip passing completely around the
vamp, and being sewn only at its upper edge to the vamp at any desirable height
or distance from the lower edge thereof, but otherwise free from same.
After the strip has been attached the upper is lasted and its lower edge secured
to the leather or other insole in the ordinary way, the strip of frictioned stock
remaining free and untouched.
Following the lasting together of the upper and insole of the boot I cover with
cement, the outside surface of the insole and the portions of the upper attached
thereto, taking the precaution, if necessary, to roughen to some extent, the portions
of the upper receiving the cement in order to ensure its better adherence, and it is
also weil to even up any hollows by scrap filling, strips etc.
After the necessary surface is well covered with cement, as mentioned, I apply a
rubber insole and last the lower edge of the strip to such rubber insole with
cement.
I then apply (securing it by cement) an outer cover or finishing strip, .the upper
edge of which is practically flush with or slightly above that of the connecting
strip, while the lower edge extends inward somewhat beyond the edge of the sole.
Thus far it will be seen that the rubber insole and strip of frictioned stock go to
form what I term an intermediate water-proof retaining section or layer, to which
the thick outer rubber sole and heel can be securely affixed with a much greater
certainty of adhering than if attached directly to the leather insole since the
rubber insole being overlapped by the frictioned stock and this latter stitched to
the upper, it is practically impossible for such rubber insole to become disconnected
from the upper even should it fail to adhere to the leather insole and consequently
the permanent connection of the outer rubber sole is ensured.
Should it be desired however to dispense with the rubber insole the outer sole in
lighter grades of foot wear can be attached directly to the connecting strip.
The outer sole and heel are secured in the usual way by cementing under
pressure, the rubber portion of the article, varnished and the complete boot finally
placed in the usual vulcanizer to vulcanize the rubber portions.
I might also point out that the outer finishing strip while serving to cover up the
stitching and so improve the appearance of the article as well as to protect such

page_text: strtening also sets in conjunction with the intermediate rubber retaining section
to prevent any possibility of leakage, a fault not uncommon in all forms of
foot wear.
A light form of shoe such as a tennis shoe might be made with simply the
outsole, vamp and the connecting strip sewn to such vamp, any suitable sock lining
or slip-sole being if desired inserted.

Rubber Soled Foot wear.
I, CHARLES LEANDER HIGGINS, of No. 178 Inspector Street, in the City of
Montreal, in the District of Montreal' and Province of Quebec, Dominion of
Canada, Manager, 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 that class of foot wear having an upper of leather, felt
or other textile material, and a rubber sole portion; the object being to secure a
stronger and more permanent connection between the sole and the upper, as well as
to render same less liable to leakage.
The invention consists in the method of attaching the rubber sole to the upper,
and in the construction of the complete article as hereinafter described, and
particularly pointed out in the claims, and for full comprehension thereof reference
must be had to the annexed drawings forming a part of this Specification in which
like symbols indicate corresponding parts and wherein
Figure 1 is a side elevation of a complete boot formed with leather upper and
rubber sole attached according to my invention.
Figure 2 is a transverse section of same on line Fig. 1, but drawn to a
larger scale.
Fig. 3 a perspective view of a boot vamp or upper with a strip of frictioned
stock frictioned on both sides required in carrying out my invention, attached.
To the unlasted vamp or upper of any foot covering such as a boot or shoe
whether of leather, felt or other textile fabric, (the upper a of a leather boot being
shown) attach, preferably by stitching according to the zig-zag fashion shown
at a¹ in Fig. 3, a connecting strip 6 preferably of what is known to rubber foot
wear manufacturers as "frictioned stock," and consisting of a textile fabric having
a slight coating of rubber to ensure better adhesion thereto of a sheet rubber
covering, the said strip b passing completely around the vamp and being sewn only
at its upper edge to the vamp at any desirable height or distance from the lower
edge thereof, but otherwise free from same.
After the strip has been attached the upper is lasted and its lower edge secured
to the leather or other insole c in the ordinary way, the strip of frictioned stock
remaining free and untouched.
Following the lasting together of the upper and insole of the boot I cover with
cement the outside surface of the insole and the portions of the upper attached
thereto, taking the precaution, if necessary, to roughen to some extent, the portions
of the upper receiving the cement in order to ensure its better adherence, and it is
also well to even up any hollows by scrap filling, strips &c.
After the necessary surface is well covered with cement, as mentioned, I apply a
rubber insole d and last the lower edge of the strip b to such rubber insole with
cement.

page_text: I then apply (securing it by cement) an outer covering or finishing strip e, the
upper edge of which is practically flush with or slightly above that of the
connecting strip 6 while the lower edge extends inward somewhat beyond the edge
of the sole.
Thus far it will be seen that the rubber insole and strip of frictioned stock go to
form what I term an intermediate waterproof retaining section or layer, to which
the thick outer rubber sole f and heel g can be securely affixed with a much greater
certainty of adhering than if attached directly to the leather insole since the
rubber insole being overlapped by the frictioned stock and this latter stitched to
the upper, it is practically impossible for such rubber insole to become disconnected
from the upper even should it fail to adhere to the leather insole and consequently.
the permanent connection of the outer rubber sole is ensured.
Should it be desired however to dispense with the rubber insole the outer sole in
lighter grades of foot wear can be attached directly to the connecting strip b.
The outer sole and heel are secured in the usual way by cementing under
pressure, the rubber portion of the article varnished and the complete boot finally
placed in the usual vulcanizer to vulcanize the rubber portions.
I might also point out that the outer finishing strip e while serving to cover up
the stitching a' and so improve the appearance of the article as well as to protect
such stitching also acts in conjunction with the intermediate rubber retaining
section to prevent any possibility of leakage, a fault not uncommon in all forms of
foot wear.
A light form of shoe such as a tennis shoe might be made with simply the
outsole, vamp and the connecting strip sewn to such vamp, any suitable sock lining
or slip-sole being if desired inserted.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In the manufacture of rubber soled foot wear; first attaching to the outer
surface of the unlasted vamp or upper of the boot or shoe, a connecting strip of
frictioned stock; then lasting the upper to the usual insole of the boot or shoe ;
securing an insole of rubber to the insole proper and lasting said connecting strip
to the rubber insole; applying an outer finishing strip over the connecting strip,
and finally attaching the rubber outsole.
2. In the manufacture of rubber soled foot wear, first attaching by stitching to
the outer surface of the unlasted vamp or upper of the boot or shoe, a connecting
strip of frictioned stock; then lasting the upper to the usual insole of the boot or
shoe; securing an insole of rubber to the insole proper and lasting said connecting
strip to the rubber insole; applying an outer finishing strip over the connecting
strip, and finally attaching the rubber outsole.
3. A boot or shoe having the usual upper or vamp and insole, a rubber outsole
and an intermediate waterproof connection between such outsole and the vamp,
such waterproof connection extending upward from the sole and being stitched at
its upper edge to said vamp for the purpose set forth.
4. A rubber soled boot or shoe having an intermediate waterproof retaining or
connecting strip secured to and extending upward from the sole and being stitched
at its upper edge to the vamp of the boot or shoe for the purpose set forth.
5. A boot or shoe having the usual upper or vamp and insole, a rubber outsole
and an intermediate waterproof retaining section for the purpose set forth.
Dated this 19th day of March 1895.
