COMPLETE SPECIFICATION.
A New or Improved Solepiece for Boots or Shoes.
I, GUSTAV KEMNITZ, of 28A Prenslauerstrasse, Berlin, in the Empire of Germany,
Shoemaker, do hereby declare the uature 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:-
The object of the present invention is an elastic layer or sole piece for shoes, which
in the absence of any pressure thereon curves upward through the action of a spring
or springs but which, upon a step being taken by the wearer of the shoe, is stretched in a
horizontal direction, and not only prevents shocks to the wearer when walking,
practising gymnastics or engaging in any kind of sport, but tends to prevent flat-
footedness and secure a constantly good fit of the shoe.
In the accompanying drawings, the new inlaid piece or sole is illustrated as
follows:-
Figure 1 is a plan view of the sole-piece.
Figure 2 is a side view of the sole-piece in the curved position.
Figure 3 is a side view of the sole-piece in the straightened position.
Figure 4 is a section through the lower part of a shoe fitted with my sole-piece.
Figure 5 is a sectional plan view of said shoe.
Figure 6 is a section through the lower part of a shoe, showing the sole-piece in its
curved position.
A metallic solepiece a curved and corresponding in shape to the sole proper of the
shoe, and provided with openings b for the purpose of ventilation and to ensure light-
ness, is held in the curved position by ineaus of the spring-c. The springs care
attached at one end to the plate d and at the other end to the sole-piece a.
The plate d is secured to the toe end of the sole-piece a by means of the rivet g.
Hence when the foot of the wearer is not exerting pressure upon the sole-piece a the
springs c exerting their force at the points g and h of the sole piece a cause it to tend
to buckle in the manner shown in Figure 6.
Upon the foot of the wearer exerting pressure on the sole-piece a the springs care
extended and the sole-piece a then takes up the position shown in Figure 4.
The inlaid piece or sole a is placed between the welt and the sole proper fand
upon a step being taken by the wearer of the shoe, stretches under resistance of the
spring c to the position shown in Figure 3.
In Figures 4. 5. and 6 the springs c are illustrated in position in the shoe. They
are attached as aforesaid at their forward ends to the plate d, shown in dotted lines in
Figure 5, and are placed between the sole proper fand the inner sole e, shown in
Figure 4.
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
An elastic layer or inlaid sole for shoes, consisting of a metallic sole-piece provided

page_text: with a spring or springs the action of which is to unintain the said sole-piece in a
curved position substantially as set forth.
