Improvements in Boots and Shoes.
I, JOHN ERNEST KENNEDY, of 666 St. Urbain Street, in the City and District of
Montreal, Province of Quebec, Canada, Advertising 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 a novel method of attaching a sole of india rubber
and the like to the lasted upper of a boot or shoe, and it consists in the novel
construction and combination of the parts hereinafter fully described and claimed.
In the accompanying drawings, forming part of this Specification, Figure 1 is
a perspective view of an outer sole constructed according to this invention ;
Figure 2 is a perspective view of the upper of my shoe, lasted and held tempor-
arily in position by a cement securing edge of the upper to the insole; Figure 3
is a cross-section through the soles.
Similar letters refer to similar parts throughout the several views.
A is an insole preferably of woven or matted material impregnated or coated
on its outer side with india rubber, but may be of any material to which an
adhesive can be applied.
B is the edge of the shoe upper previously drawn into position over a thin
coat of cement or of tissue impregnated with cement (and laid between the edges
of the upper and the insole) and held there by stitches across the sole till cement
has been set, under pressure, by heat, evaporation, etc.
C is a series of perforations through the leather of the upper (near its edges),
either in one or more rows, and exposing the outer surface of the insole through
those perforations.
D is the outer edge of the outsole which is moulded from rubber or other flexible
composition.
66
E is an elevated portion of the outsole designed to take the place of ordinary
filling " between the outer sole and the insole. This elevated portion is of
about even height with the thickness of the upper leather, and is cemented or
solidified on to the insole by vulcanizing or by any other approved method.
Fis a series of projecting teeth set in a concaved groove F and formed on
the outsole in the moulding, cemented, vulcanized or otherwise secured onto the
outsole after it has been moulded, and adjusted so as to fit into the perforations C
through the upper, and come in contact with the insole, or similar perforations
in the insole, or through a strip of material attached thereto, to which they are
vulcanized, cemented, or secured in any other approved manner.
These teeth when made fast to the insole, act as a stitch, and by means of the
concaved groove F having been held in compression, while vulcanizing or other-
wise attaching the teeth to the insole, draw the shoulder G tightly against the
apper, and bind it there.
The insole A is made of asbestos, felt, cotton, wool or other suitable material,
mpregnated or coated on its lower or outer surface with india rubber or other
ike composition, and cemented or vulcanized onto the elevated portion E of the
outsole.

page_text: It is obvious that various changes may be made in the construction and details
without departing from the spirit of my invention, such as omitting the series
of projections F and filling the' perforations C of the upper with either round
pieces of sole rubber, liquid rubber, cement etc., and then uniting the insole and
outsole by vulcanizing, cementing, etc.
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
1. The attachment of a sole to a shoe by means of teeth projecting from the
said sole, passing through perforations near the edge of the upper, and then being
vulcanized, cemented, or fused onto the insole, substantially as set forth.
2. The combination with an upper provided with a series of perforations near
its lower edges; of an insole of asbestos, cotton, wool or other suitable material,
impregnated or coated with india rubber on its outer or lower surface, and a sole
and heel of india rubber, or other suitable material having an elevated section E
adapted to be vulcanized, cemented, or fused onto the portion of the insole which
is not covered by the overlapping edge of the upper, and a series of teeth formel
or set into a concaved channel, these teeth passing through the perforations in
the upper and then the whole vulcanized, cemented or fused onto the insole,
substantially as set forth.
3. The herein described shoe composed of an insole and outsole of suitable
material amalgamated into a solid piece and binding the upper by means of teeth
between the edges of the insole and outsole, substantially as described and for
the purpose set forth.
4. The improved method of attaching a rubber sole to a rubber insole, sub-
stantially as set forth.
