Year: 1862

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the
County of Middlesex, Engineer and Patent Agent, for the Invention
of "IMPROVEMENTS IN THE MEANS OF APPLYING HEAT TO THE FEET IN BOOTS,
SHOES, AND OTHERWISE, PART OF WHICH IMPROVEMENTS IS APPLICABLE TO OTHER
HEATING PURPOSES."-A communication from abroad by Jean Marie
Bibet, Emile Léger, and Antoine Faury, all of 29, Boulevart St. Martin,
Paris.
Sealed the 16th June 1868, and dated the 24th December 1862.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 24th
December 1862.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MEANS OF APPLYING HEAT TO THE FEET IN
BOOTS, SHOES, AND OTHERWISE, PART OF WHICH IMPROVEMENTS IS APPLICABLE TO
OTHER HEATING PURPOSES," to be as follows:-
Various methods have been employed for warming the feet, which are how-
ever defective, and do not answer the purpose required.
This Invention relates to an improved apparatus of simple construction to
be applied to the heel of a boot or shoe for the purpose of warming the foot
without danger of burning it. It consists of a hollow metal hcel with a false

page_text: bottom, which is hinged to a metal sole piece, and serving to contain the
charcoal used for transmitting warmth to the foot. The combustion of the
charcoal when once lighted is maintained by the admission of cold air, which
will distribute the heat throughout the boot or shoe. I apply a metal gauze to
neutralize the effect of too strong a flame, which would be apt to burn the
foot. The lump of charcoal is maintained in position by means of a spring,
the parts are held closed by means of a spring, button, or pin, which also serves
for throwing off mud, or a spur may be substituted for the pin above men-
tioned.
Fig. 1 of the annexed Drawing represents a central vertical section of this
improved heating apparatus; and Fig. 2, a plan of same.
a, heel, with double-bottom hinged to the sole piece bat c; d, air inlet
orifices made in the periphery and under part of heel a in order. to produce
combustion of the charcoal f, which is termed carbon paste, and is moulded in
the form of a horse-shoe, this charcoal is placed in heel a on the wire gauze g,
being secured therein by another gauze covering h, acted on by a spring i, on
which the heel bears; j, screw button for securing the heel closed, which also
serves to throw off mud. The metal sole piece or camber 6 is pierced with
holes in order to fix it to the leather sole of the boot or shoe; m, metal
stiffening of a piece with the sole piece b, and furnished with holes n for
securing it to the leather stiffening piece.
The Invention consists of the improved heating apparatus for the heels of
boots and shoes as above described, and also in the application of the carbon
paste herein described for heating foot warmers, plates, kettles, and all articles
other than ordinary fire-grates.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the 22nd
June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of December, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Clark, Her special licence that I, the said William Clark,

page_text: my executors, administrators, and assigns, or such others as I, the said
William Clark, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "İM-
PROVEMENTS IN THE MEANS OF APPLYING HEAT TO THE FEET IN BOOTS AND SHOES,
AND OTHERWISE, PART OF WHICH IMPROVEMENTS IS APPLICABLE TO OTHER HEATING
PURPOSES," a com". to me from abroad by Jean Marie Bibet Emile Léger
and Antoine Faury, all of 29, Boulevart St. Martin, Paris, upon the condition
(amongst others) that I, the said William Clark, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
. NOW KNOW YE, that I, the said William Clark, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention relates to an improved apparatus to be applied to the heels
of all kinds of boots and shoes for the purpose of heating or warming the-feet,
as also to the combustible employed for such purpose.
Various methods have been employed for warming the feet, which are
however defective, and do not answer the purpose required.
This Invention relates to an improved apparatus of simple construction to
be applied to the heel of a boot or shoe for the purpose of warming the feet
without danger of burning it. It consists of a hollow metal heel with a false
bottom, which is hinged to a metal sole piece, and serves to contain the char-
coal used for transmitting warmth to the foot. The combustion of the charcoal
when once lighted is maintained by the admission of cold air, which dis-
tributes the heat throughout the boot or shoe. I apply a metal gauze to
neutralize the effect of too strong a flame, which would be apt to burn the
foot. The lump of charcoal is maintained in position by means of a spring, the
parts are also fixed by means of a spring, button, or pin, which serves for
throwing off mud, or a spur may be substituted for the pin above mentioned.
Fig. 1 of the annexed Drawings represent a central vertical section of this
improved heating apparatus; and Fig. 2, a plan of the same.

page_text: a, heel, with double bottom hinged to the sole piece b at c; d, air inlet
orifices made in the periphery and under part of heel a, in order to produce
combustion of the charcoal f, which is termed carbon paste, and is moulded in
the form of a horse-shoe, this charcoal is placed in heel a on the wire gauze g,
being secured thereon by another gauze covering h, acted on by a spring i, on
which the heel bears; j, screw button for fixing the heel, which also serves
to throw off the mud. The metal sole piece or camber 6 is pierced with
holes in order to fix it to the leather sole of the boot or shoe; m, metal
stiffening forming a part of sole piece b, and furnished with holes n for securing
it to the leather stiffening piece.
Having described the nature of this Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be protected
by the herein-before in part recited Letters Patent is, the arrangement and
construction of the improved heating apparatus for the heels of boots and shoes
as above described and represented in the Drawing annexed; also the appli-
cation of the carbon paste herein described for heating foot warmers, plates,
kettles, and all articles other than ordinary fire-places all as herein described.
In witness whereof, I, the said William Clark, have hereunto set my]
hand and seal, this Twenty-second day of June, in the year of our
Lord One thousand eight hundred and sixty-three.
Witness,
JAMES DAISH,
58, Chancery Lane,
