AN APPLIANCE FOR VENTILATING BOOTS AND OTHER FOOT-COVERINGS
Year: 1885

page_text: I, HERBERT JOHN HADDAN of 67 Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said invention for AN APPLIANCE FOR
VENTILATING BOOTS AND OTHER FOOT-COVERINGS, a communication to me from
abroad by Ernst Jesch, Manufacturer, of Leipzig, in the Kingdom of Saxony, to be
as follows:-
The chief purpose of the present invention is to afford ventilation to the sole of
the foot, and provide it with a comfortable, elastic bed.
By means of such ventilation, the perspiration from the feet of sick persons is
diminished, and this evil is, therefore, mitigated.
The contrivance may be described as follows: It consists of a perforated inner
sole or welt, below which is placed the so-called ventilating-sole made of solid
gutta-percha and separated from the welt by small studs of soft gutta-percha.
When the foot is placed on the ground, these studs are compressed, which not
only secures an easy elastic step, but also produces the action of a pump, so that
the air is sucked in and driven out alternately through a channel in the heel of the
boot and a hollow ventilating spur.
The air absorbs the moisture which gathers under the welt, and so the feet are
kept completely dry.
The ventilating spur which is perforated, can be replaced by a solid spur in
damp weather.
As will be readily understood, then; by alternately raising and setting down the
foot, an uninterrupted circulation of the air is produced, and, at the same time, an
easy, springy step is ensured by the elastic nature of the ventilating sole.

page_text: I, HERBERT JOHN HADDAN, of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declaro the nature of this invention, a communication to me
from abroad by Ernst Jesch, Manufacturer, of Leipzig, in the Kingdom of Saxony,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The purpose of the present invention, which is illustrated in the accompanying
drawing Figs. 1 to 4, is to afford ventilation to the soles of the feet and to provide
them at the same time with a comfortable, elastic bed.
.
By means of this ventilation the perspiration from the feet of sick persons is
diminished, and thus the evil is considerably mitigated.
In the accompanying drawing Fig. 1 represents a longitudinal section of a shoe
embodying the present invention, Fig. 2 shows the sole and Figs. 3 and 4 are
s-ctional details.
It will be seen that there is a perforated inner sole or welt b, below which is
placed the so-called ventilating-sole g made of solid gutta-percha and provided with
small gutta-percha studs p which separate this ventilating sole from the welt.
When the foot is put down on the ground, the elastic studs p are compressed,
which ensures an easy elastic step and at the saine time produces the action of a
.pump.
The air is thus sucked in and driven out through the channel c in the heel of
the boot and the hollow ventilating spur a.
The air absorbs the moisture, which gathers under the welt and so keeps the foot
perfectly dry.
The ventilating spur a, which is perforated, can be replaced in damp weather by
a solid spur d, Fig. 4.
It will be readily understood, that, by alternately raising and setting down the
foot, an uninterrupted circulation of air is kept up, and an easy elastic step
secured by the elastic nature of the ventilating sole g.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is
1.) A contrivance for the ventilation of boots and other foot-coverings, comprising
an inner sole or welt b, and a ventilating sole g provided with elastic studs p placed
between the two soles, and an air conduit connecting the space, between the soles
with the atmosphere, substantially as described.
2.) The combination of inner sole b and ventilating sole g, kept apart by elastic
studs, with a heel having an air conduit c communicating with the space between
the soles, and a hollow spur a adapted to admit air to the said conduct c, substan-
tially as described.
