page_text: Date of Application, 21st Nov., 1899-Accepted, 17th Mar., 1900 ***
I, JULIUS SIKORSZKY, of Miskolcz, in the Kingdom of Hungary, Shoemaker, do
hereby declare the nature of my said invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the fol-
lowing statement:-
-
The object of the present invention is to provide boots and shoes with spring
mounted or elastic soles, without however impairing their safety for walking
purposes.
In order to render the present specification easily intelligible reference is had
to the accompanying drawings in which similar letters of reference denote similar
parts throughout the several views:-
Fig. 1 is a view of the sole seen from underneath the under sole being partly
removed to show the arrangement of the springs. Fig. 2 is a view of the heel
seen from underneath, Fig. 3 is a sectional elevation of a boot Fig. 4 a rear end
elevation of the spring arrangement within the heel and Fig. 5 a side elevation
of an overshoe.
The sole is rendered elastic by means of small coiled springs ee mounted between
the plates or leathers d and c, the whole being inserted beneath the inner sole a
and the lower sole and the plates c and d being shaped in plan view to corre-
spond with the shape of the sole a.
The heel is made hollow and is provided with a plate g formed with a forward
hook and attached to the underneath surface of the upper or inner sole, a
plate falso being provided formed with a forward hook and mounted on the
bottom part of the hollow heel. Between these two plates y and f a spring i
is provided the ends of which are attached one to each of the said plates. This
spring has its bend at the rear part of the heel and its arms, extend forwardly in
the direction of the length of the shoe, so that the tendency of the spring will
always be to raise the inner sole in the direction of motion of the person wearing
the boots or shoes. The plates f and g may be attached to the interior of the
hollow heel piece by means of rivets as indicated at h or by any other suitable
means. In Figure 5 an overshoe is illustrated having the elastic inner sole a¹
consisting of the plates c and d with interposed springs ee, the said elastic sole
being mounted on the under sole b, which is attached to the hollow heel as illus-
trated, the said heel piece being constructed in the same manner as that described
with reference to Fig. 3. The heel is provided with a cap having an instep
strap m, whilst the sole b is provided with a second strap n and a third forward
strap p with toe strap r.
This class of overshoes may be easily put on and taken off and, not occupying
much room may be carried about with the person and worn when necessary.
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:-
1: In a boot or shoe the combination of an elastic sole consisting of upper and

page_text: lower plates or leathers d and c and interposed springs ee and an elastic heel,
consisting of a hollow heel piece having upper and lower plates 9 and f connected
by means of a bent spring interposed between them substantially as described.
2: The elastic sole and heel as covered by Claim 1 in combination with an
overshoe, in which the under sole b is connected to the hollow heel piece and is
provided with the elastic sole at the forward part, the said sole and heel parts
being provided with straps m, n, and p and toe strap r as specified.
