PROVISIONAL SPECIFICATION.
An Improved Construction of Boots or Shoes.
I, KARL FERDINAND JEKELI of Vienna V Herthergasse 25, Chemist, do hereby
declare the nature of this invention to be as follows:-
My invention relates to the construction of a boot or shoe in such a manner as
to provide for free movement of the foot, lightness of its covering and ventilation.
For this purpose, I prepare in the first instance a sock or stocking of elastic
material, which may be fabric knitted or woven in a manner giving elasticity,
and I stretch this on a suitable last. I coat it with solution such as that of
caoutchouc, gutta percha or the like, of more or less thickness as may be desired,
which I vulcanise. I employ the sock or stocking thus treated as the upper of
the boot or shoe attaching to it the sole and heel, back heel stiffener and elastic
sides or fastenings of any known kind. In order to ventilate it, I cut several
longitudinal grooves along the underside of the inner sole with holes at intervals
passing through that sole and through the fabric under the foot, and I continue these
grooves to mouths at the heel so as to communicate there with the outer air, or I
make their mouths communicate with small vertical tubes provided in the rear part
of the boot or shoe and leading up to the top of that part.

1, KARL FERDINAND JEKELI of Vienna V Herthergasse 25, Chemist, 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 an improved construction of boots and shoes in which
the upper is formed of a knitted, crocheted or woven elastic fabric, felt or paper,
which fabrics are coated with caoutchouc or guttapercha or mixtures thereof and
which, by impressing or cementing thereon, various designs such as binding or
seams, fronts, caps, eyelet holes, hooks &c. are made to assume the appearance of
ordinary boots and shoes.
The uppers thus prepared are firmly united to a leather sole by cementing with
caoutchouc solution and subsequent vulcanising, and are thereby made to form a
complete waterproof boot or shoe for out of door wear, which entirely replace the
ordinary goloshes.
It will be evident that soles of caoutchouc or guttapercha can also be used, and
that these three kinds of soles instead of being cemented to the uppers, can be.
secured thereto in the ordinary manner by sewing or pegging.
In addition, this new construction of boot or shoe, is provided with a ventilating
device for enabling the feet to perspire freely.
The uppers constructed as above described fit accurately to the shape of the foot,

page_text: without exerting any undue pressure on tender parts, and they are therefore
particularly suited for tender or suffering feet.
The mode of manufacture of such foot coverings is as follows:
The fabric forming the foundation of the upper is stretched over a last on
which has been previously fixed a roughened leather sole coated with a solution of
one of the above mentioned waterproofing substances, and the whole thus forms a
stocking-like covering; or an actual stocking may be used for this purpose.
This covering is then coated repeatedly with the said solution until the coating
has the desired thickness, or thin sheets of caoutchouc, gutta-percha, or mixtures of
these, may be cemented or sewn on to the foundation, instead of coating this as
described.
To the fabric thus prepared, which replaces the ordinary leather upper, the
previously roughened sole of leather, caoutchouc or guttapercha coated with the
above named solutions, is secured by cementing, sewing or pegging.
To the upper is then imparted the appearance of an ordinary boot or shoe by
impressing or cementing thereon designs such as binding, seams, front cap, eyelet
holes, hooks &c., and it is then subjected to the ordinary vulcanising process, after
which the foot covering is finished off in any known manner.
The arrangement for providing ventilation to such foot coverings is shewn on
the accompanying drawings: Fig. 1 shews a longitudinal section, Fig. 2 a cross
section, Fig. 3 a sectional plan of a boot having such ventilating device applied
thereto.
The inner sole a has one or more chaunels formed in it, which open to the
outside at the heel piece or at any other convenient point. These chanuels a' com-
municate through openings a with the inside of the boot; the channels may also
be extended up the back of the boot, as at b.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. Boots and shoes having an upper consisting of a knitted, woven, or crocheted
elastic fabric, felt, or paper which is coated with caoutchouc or guttapercha, or
mixtures of these substances which may be coloured, or the said fabric may have
secured thereto sheets of caoutchouc or paper coated with caoutchouc, substantially
as described.
2. The combination with an upper such as is referred to in the first claim, of a
leather sole and heel to form boots or shoes for outdoor wear, the leather sole
being cemented to the upper by a caontchouc solution, and firmly secured thereto
by subsequent vulcanisation, substantially as described.
3. The combination with an upper such as is referred to in the first claim, of a
leather sole and heel secured thereto in the usual manner by sewing or pegging,
substantially as described.
4. The combination with an upper such as is referred to in the first claim of a
sole of caoutchouc secured thereto by cementing, sewing or pegging, substantially
as described.
5. In the construction of boots and shoes such as is referred to in the 2nd, 3rd
and 4th claims providing means for ventilation consisting of channels a¹ formed
between the soles a, which channels open on the one hand to the outer air and on
the other hand communicate by openings a² with the interior of the boot or shoe,
substantially as described.
