We, LEONIDAS NICHOLAS THIERRY, and THOMAS ERNEST PENROSE, of
34 Poultry, London, E.C., Bootmakers, do hereby declare the nature of this
invention to be as follows:-
This invention is designed to supply a boot or foot covering for the use of
persons whose occupation obliges them to walk over heated floors or near furnaces
or amid sparks, or who are in danger of treading on cinders or fragments of heated
iron and the like.
It consists of utilising woven or felted asbestos, either alone or mixed with other
suitable material, and used either externally or partly so, or internally, or both, or
as an envelope or wrapper, or in any other convenient way, as a foot covering or
protection for the feet against the evils resulting from exposure to heat or contact
with heated substances.

We, LEONIDAS NICHOLAS THIERRY and THOMAS ERNEST PENROSE of
34 Poultry, London E.C., Bootmakers 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 is designed to supply a protective boot or foot covering for the
use of persons whose occupation obliges them to walk over heated floors, or near
furnaces, or amid sparks, or who are in danger of treading on cinders or fragments
of heated iron and the like.
It consists of utilising woven or felted asbestos, either alone or combined or
mixed with other suitable material, and used either externally or partly so, or
internally, or both, or as an envelope or wrapper, or in any other convenient way,
as a foot covering or protection for the feet against the evils resulting from exposure
to heat or contact with heated substances.
Our invention can be employed practically in the following four ways, or in any
combination of these, namely
1. As a layer of the asbestos material interposed between the insole and outsole
of the boot or shoe. This layer is by preference carried right through to the back
of the heel, and may be either one undivided piece, or formed of two or more parts,
and joined or connected in some suitable way.
2. The asbestos may be used as an outside layer on the surface of the leather
sole, or of the sole and heel. In this case it may be formed as an ordinary com-
pressed mill-board, or mixed with some suitable uninflamable composition. To
prevent its being rapidly disintegrated by friction in wear, it may be covered with
DQ27

page_text: a mesh of woven wire or fire-proofed cord. It may also be used as a loose sole or
clog, and fastened by laces ties or straps.
3. Another mode of employing it is as a partial or entire lining for the inside.
This is not so desirable a plan when the heat to be encountered is considerable,
since it affords no protection to the leather of which the boot is composed, but it
may be useful in special cases.
4. The asbestos woven or felted, with or without some textile material fireproofed
in any well known way, or combined with some suitable composition, may be
employed as a cover or exterior envelope for the upper part of the boot or shoe, or
as a layer between the leather "upper" and the usual lining. This cover and layer
may be partial or entire as preferred.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The employment of asbestos either woven or felted, either alone or combined
with some suitable composition or other material, as a lining, layer loose sole or
cover partial or entire, in the construction or protection of boots and shoes as
herein described and set forth.
