PROVISIONAL SPECIFICATION.
Improvements in Boots and similar Foot Coverings.
I, LOUIS ECKHARDT, Manufacturer, of Homburg / Höhe, Germany, do hereby
declare the nature of this invention to be as follows:
My invention relates more particularly to the means for ventilating the soles of
boots and shoes, and for obtaining a certain degree of elasticity.
The insole as well as the outer sole or main sole, is provided with holes placed out
of line, in such a manner that the holes in the insole will not coincide with those in
the outer sole; and vice versa.
Between the outer and the inner sole passages are formed, by inserting into the
openings of the main sole india rubber plugs, provided at the top with flat square
heads, and the heads of adjoining plugs may be connected, so as to form continuous
strips. These heads or strips are thus situated between the two soles, and form air
passages which communicate with the holes of the insole and allow air to enter the
interior of the boot.
The plugs situated in the holes of the main sole prevent the india rubber heads
from shifting, and according as the same are made longer or shorter, they project
more or less below the main sole, so as to render the tread elastic and sure.
At certain places near the edge, the main sole and the insole are connected with
each other by seams, pegs, nails or screws; but so as to leave lateral openings which
allow the external air to enter, and the inner air to escape and which may be protected
against snow or water by a porous but waterproof tape or band, laid round the edge
of the sole and secured thereto by suitable means. In the case of winter boots, the
lateral openings may be omitted or permanently closed.
The heel may be ventilated and rendered elastic in the same inanner as the sole.

COMPLETE SPECIFICATION.
Improvements in Boots and similar Foot Coverings.
I, LOUIS ECKHARDT, Manufacturer, of Homburg / Höhe, Germany, 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:-
My invention relates more particularly to the means for ventilating the soles of
boots and shoes, and for obtaining a certain degree of elasticity.
The insole, as well as the outer or main sole, is provided with holes placed out of
line, in such a manner, that the holes in the insole will not coincide with those in the
outer sole; and vice versa.
Between the outer and the inner sole passages are formed, by inserting into the
openings of the main sole india rnbber plugs, provided at the top with flat square
heads, and the heads of adjoining plugs may be connected, so as to form continuous
strips. These heads or strips are thus situated between the two soles; they keep the
sanie apart from each other and form air passages which communicate with the holes
of the insole and allow air to entor the interior of the boot.
The plugs situated in the holes of the main sole prevent the india rubber heads
from shifting, and according as the same are made longer or shorter, they project
more or less below the main sole, so as to render the tread clastic and sure.

page_text: At certain places near the edge, the main sole and the insole are connected with
each other by seams, pegs, nails or screws; but so as to leave lateral openings
which allow the external air to enter, and the inner air to escape and which may be
protected against snow or water by a porous but waterproof tape or band, laid round
the edge of the sole and secured thereto by suitable means. In the case of winter
boots, the lateral openings may he omitted or permanently closed.
The heel may be ventilated and rendered elastic in the same manner as the sole.
In the accompanying drawings,
Fig. 1 represents a complete shoe embodying my invention,
Fig. 2 represents the perforated mainsole and Fig. 3 tho insole likewise provided
with perforations:
Fig. 4 represents an india rubber plug of the kind described ;
Fig. 5 is a partial section of the "mainsole and insole showing a series of plugs
and of perforations, on a large scale.
Fig. 6 is a plan after removal of the insole, corresponding to Fig. 5.
Fig. 7 shows several india rubber plugs connected with each other, so as to form
a strip.
In these figures A. represents the mainsole, B the insole, a the heads of the plugs.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, 1 declare, that 1 claim
A boot (or similar foot covering) having a perforated insole, a perforated main-sole
the holes of which are out of line with those of the insole, and india rubber plugs
passing through the said holes of the mainsole, the said indiarubher plugs being
provided with beads a adapted to form between the two soles air passages which
communicate with the interior of the boot through the holes of the insole and (if
desired) with the atmosphere through openings left between the two soles at the edges
thereof, substantially as described.
