COMPLETE SPECIFICATION.
Improvements in Boots and Shoes.
We, HANS THOMANN, of 24, Sulzbacherstrasse, Nuremberg, in the Empire of
Germany, Shoemaker, ALBERT EITEL, of 49, Rahm, Nuremberg, aforesaid, Lock-
smith, and FRIEDRICH PROEGER, of 50, Bucherstrasse, Nuremberg, aforesaid,
Merchant, 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:-
This invention relates to improvements in boots, shoes, and the like, the
object being to provide the heel of the shoe with a firebox or heated chamber,
and the sole with flues so that the foot is made and kept warm.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the annexed drawings,
in which :-
Fig. 1 is a sectional view of an improved shoe as seen from the underside.
Fig. 2 is a side view of the boot the lower part being shewn in section.
According to this invention the heel of the shoe is hollow and contains a fire-
box 1 closed by a lid 2 and having on its back a little tube 3 allowing the
entrance of air to the fuel in the said box. The sole also is hollow and encloses
a flue 4 projecting from the fire box to near the toe of the shoe and forming
with the side walls or solid edges of the shoe two passage ways or flues 5, 5 for
the passage of the heated gases from the toe back again to the heel of the boot or
shoe.
Several small blocks 6 of a non-conducting material are placed in the hollow
sole and around the said flue so as to distribute the heated gases and also to bear
the inner sole 7 which extends over the lid 2 and on which insole the foot of
the wearer rests.
When the
The heel is provided with an opening 8 for the escape of gas.
shoe is to be warmed, fuel in a burning state or slowly being consumed by fire
is placed in the box 1 which is then closed by the lid 2 covered with the inner
sole 7.
The heated gases pass from the fuel 4 to the toe of the shoe and thence back
through the hollow sole to the heel and escape through the opening 8. In its
way the heated gas is diverted by the blocks 6 and distributed over all parts
of the sole in order to warm the whole foot.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
-
(1) In coverings for the feet a hollow heel constituting a firebox 1 closed by
a lid 2 and having a tube 3 for the entrance of air to the fuel and an opening 8
for the escape of gas, all in combination as and for the purpose herein described
and substantially as illustrated by the annexed drawings.
(2) In coverings for the feet a hollow sole connecting a firebox or heating
chamber in the heel with the toe of the boot or shoe and passage ways or flues 5°
