page_text: Date of Application, 13th Nov., 1899-Accepted, 23rd Dec., 1899
We, JAMES DIXON COOPER, of 49, McCaul Street, in the City of Toronto, in the
County of York, in the Province of Ontario, Canada, and MARY HALE, also of
49, McCaul Street, in the City of Toronto, in the County of York, in the Province
of Ontario, Canada, 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:-
-
Our invention relates to improvements in slipper soles more particularly
adapted for bedroom slippers, and the object of the invention is to devise a strong
durable sole in which the upper may be connected thereto very securely, durable
and cheaply, and it consists essentially of a slipper sole made of one thickness
of leather having a channel or slit cut around the edge from the inside and
extending into proximity with the upper corner, and a row of stitching extending
through the bottom of the channel and this portion of the sole to the apex or
upper corner of the edge of the sole, as hereinafter more particularly explained.
Fig. 1, is a perspective view of a slipper sole adapted particularly to receive
a knitted or crocheted fabric upper.
Fig. 2, is a perspective view of a portion of the sole showing the way the
channel is cut and turned out in order to make the stitching.
-
Fig. 3, is a cross section showing at one side the flap, of the channel turned
down and the channel open and at the opposite side the channel cemented and the
stitching in place.
Fig. 4, is an enlarged alternative form showing the upper connected to the
stitching.
Fig. 5, is a detail of a still further alternative form of leather sole.
In the drawings, like letters of reference indicate corresponding parts in each
figure.
A is the main body of the sole. The sole A, on reference to Figs. 1, 2, and 3,
is provided with a channel a, cut from the inside towards the upper apex or
corner of the edge of the sole, a flap a¹, being formed in the process of cutting,
which is done by any suitable machine adapted for this purpose. The sole is
then stitched from the channel and up to the upper apex or corner a², of the edge,
which is preferably bevelled off at a³, as shown.
The stitching C, extends or projects outwardly from the corner and by a series
of stitches extending around the upper corner to the edge of the sole a series
of loops are necessarily formed whereby the knitted or crocheted fabric may he
secured in position. Of course it is not necessary that the upper should be a
knitted or crocheted fabric but any other suitable material might be with facility
connected to the stitching, as shown.
In Fig. 4, we show an upper B, attached by the stitching C, to the upper
corner of the edge of the sole. The lower edge of the upper, however, extends
into a right angular groove a, cut in the corner instead of the bevelled portion
referred to in the former figures.
In Fig. 5, we show the channel cut from the inside at the top down and along

page_text: towards the upper corner or edge of the sole, the stitching C, being secured in
position and projecting from the upper corner as hereinbefore described.
In all of the forms, it will be noticed that it is adapted to have the channel extend
into proximity with the upper corner of the edge of the sole and to always cut
the channel from the inside towards the corner instead of as is usual in the
manufacture of shoes cutting the channel from the outside to the inside at the
Eottom of the sole.
It will of course be understood that the flaps a', in every instance are cemented
down in position and that the bottom surface of the sole is thereby strong and
will last quite a length of time.
Heretofore slipper soles of this class have been frequently made of card board
and covered with thin leather and having a cord stitched into the leather where
it is turned around the upper corner of the edge of the sole. There are various
makes in which this sole is employed in varied forms but necessarily the life
of such a sole seeing that the leather is just a thin cover is but short.
By our construction of sole it will be readily understood that the sole being
of leather throughout and the stitching being secured in the manner as herein-
before described the life of the sole particularly as in the preferred form as shown
in the first three figures is lengthened to a maximum extent.
The form of stitch we use in the manufacture of our sole is preferably chain
stitch and it will be understood that once the flap of the channel is cemented down
in position the inner end of the flap pinches upon the stitching so that when
the sole has become worn and one or more stitches give, it necessarily follows
that the remaining stitches will not give but be held in place by the inner end
of the flap of the channel.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. A sole for slippers comprising a solid layer of leather having a channel cut
from the inside towards the upper apex or corner, the flap of the channel being
cemented down in position, and a row of stitching extending from the inside of
the channel to the upper corner of the edge of the sole, as and for the purpose
specified.
2. A sole for slippers comprising a layer of leather properly shaped and having
the upper corner of the edge cut away around the entire sole, a channel cut from
the inside towards the upper apex or corner, the flap of the channel being
cemented down in position, and a row of stitching extending from the inside of
the channel to the upper corner of the edge of the sole, as and for the purpose
specified.
Dated this 13th day of November 1899.
