Improvements in the Manufacture of Boots and Shoes.
1, THOMAS SMITH, 11 Villa Road, Nottingham, Boot and Shoe Manufacturer do
hereby declare the nature of this invention to be as follows:-
In the heel of each boot or shoe I form a cavity extending from the top piece and
lower lift to the insole, the cavity is supplied with air through a number of brass
tubes let in the heel below the insole, the tubes at the side and back of the heel have
their outer ends flush or nearly so with the outside, their inner ends within the cavity
are each provided with a valve which prevents the return of the air, the remaining
tubes are open at each end, the front end of each terminating in a helically coiled
spring lying between the sole and insole, above which is a layer of felt or equivalent
material which with the insole is perforated throughout in the part not covered by
the welt and portion of the heel, the cavity in the heel is provided with a strong
open coiled spring which supports the heel of the wearer, the weight of the heel
slightly presses downward the insole at the heel, which when in use forces the
air from the cavity, through the open ended tubes and springs, to and through
the perforations in the insole thereby securing a perfect ventilation in each boot
or shoe.

page_text: I, THOMAS SMITH 11 Villa Road Nottingham Boot and Shoe Manufacturer 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:
and springs hereafter referred to.
Figure 2 shows an underside view of the sole and portion of the heel having a
cavity containing a spring and two tubes each provided with a valve.
Figure 3 is a sectional view of the sole and portion of the heel.
Figures 4 show edge views of a top piece G and lower lift G².
Figure 5 shows a side view of a boot or shoe provided with my improvements when
in a finished state.
In the heel of each boot or shoe I form a cavity A extending from the top piece
and lower lift to the insole (see Figures 1 and 3) the cavity is supplied with air
through a number of brass tubes B two only are shown in the drawings" let in the
heel below the insole, the tubes have their outer ends flush or nearly so with the out-
side of the heel, their inner ends within the cavity are each provided with a weighted
valve B which prevents the return of the air to the outside.
The remaining tubes C are open at each end, the front end of each terminating in
a helically coiled spring C lying between the sole D and insole E, above the sole
between it and the insole is a layer of felt, cork or equivalent material F which with
the insole is perforated by perforations F throughout in the parts not covered by the
welt and portion of the heel.
The cavity in the heel is provided with a strong open coiled spring G below the
insole which supports the heel of the wearer, after the insertion of the spring in
the heel a top piece G and lower lift G2 is secured in position, and the sole and heel
are finished in the usual way, presenting the appearance shown in side view at
Figure 5.
Boots and shoes provided with the above improvements when in use have the insole
of the heel slightly pressed downwards by the weight of the wearer each time the
heel is brought to the ground forcing the air from the cavity through the open ended
tubes and springs to and through the perforations in the insole thereby securing a
perfect ventilation in each boot or shoe.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is
For forming a cavity A in the heel of each boot or shoe and inserting an open
coiled spring G therein, providing each heel with two or more tubes B each having
a weighted valve B' within the cavity, and placing open ended tubes C, and springs C
between the perforated insole F and the sole D to assist in forming a ventilated boot
or shoe substantially as described and illustrated in the Drawings annexed.
