page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County
of Middlesex, Engineer & Patent Agent, for the Invention of "A
HEATING APPARATUS FOR BOOTS AND SHOES, AND OTHER COVERINGS FOR THE
FEET." A communication from abroad by Messieurs Bibet, Léger, &
Faury, of 29, Boulevart St. Martin, Paris, Merchants.
Sealed the 8th June 1860, and dated the 14th December 1859.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 14th
December 1859.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer & Patent Agent, do hereby declare the nature of the said Invention
for "A HEATING APPARATUS FOR BOOTS AND SHOES, AND OTHER COVERINGS FOR
THE FEET," to be as follows:-
For this purpose a small lamp is fitted in a hollow heel of any kind of boot
or shoe, or other covering. The products of combustion circulate through
small metallic tubes arranged in between the soles and opening to the exterior,
or the products of combustion may be made to heat a metal sole placed inside
a sole of leather. The entire plate would be heated by the conductability of
the metal. The supply of air is obtained by means of openings made in the
heel. The heel is hinged or otherwise jointed for the purpose of opening and
shutting it.

by the said William Clark in the Great Seal Patent Office on the
13th June 1860.
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 Fourteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Williani Clark, Her special licence that I, the said William
Clark, 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
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Bri-
tain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"A HEATING APPARATUS FOR BOOTS AND SHOES, AND OTHER COVERINGS FOR THE
FEET," a communication from Messieurs Bibet, Léger, & Faury, of 29,
Boulevart St. Martin, Paris, Merchants, upon the condition (amongst others)
that I, the said William Clark, my executors or administrators, by an instru-
ment 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 heating apparatus for boots and shoes and other
coverings for the feet. For this purpose a small lamp is fitted in a hollow
heel of any kind of boot or shoe or other covering. The products of com-
bustion circulate through small metallic tubes arranged between the soles and
opening to the exterior, or the products of combustion may be made to heat a
metal sole placed inside a sole of leather. The entire plate would be heated
by the conductability of the metal. The supply of air is obtained by means of

page_text: openings made in the heel. The heel is hinged or otherwise jointed for the
purpose of opening and closing it.
This Invention is illustrated in the annexed Drawing, in which Fig. 1 shows
an elevation; Fig. 2, a vertical section of the lamp; Fig. 3 shows the lamp
half open; & Fig. 4 shows the metallic plate fitted in the sole. a, shoe of
any kind of leather; b, metal heel adjusted under the sole of the boot; c, sole
of the shoe; in this sole are small metallic tubes, and it is in these tubes that
the products of combustion circulate; d, thumbscrew, serving to fix the metal
heel; e, hinge connecting the metal heel of the sole to the boot or shoe;
f, opening for the passage of air necessary for combustion; g, opening for the
passage of the warm air; h, copper plate fixed to the bottom of the heel, and
kept in place by screws or pins i.
Having described Fig. 1, I will now describe Fig. 2, which shows a vertical
section of the lamp. j, portion of the lamp which fixes to the shoe; k, openings
made for sewing the hollow portion of the heel lamp; to the shoe; l, sheet of
cork covering the surface of the heel and the camber; m, plate of copper,
serving to conduct the heat; this plate is covered with Morocco leather, of
which plate the extremity forming the heel is warmed by an orifice made over
the flame; n, plate with opening, which serves to intercept the two currents
of air comprised in the spaces u & v; o, socket, serving as a stopper;
P, receptacle for oil, it is kept closed by means of the socket o; q, opening
for the introduction of air; d, button head of screw, for fixing and closing the
metallic parts of the heel; r, frame in which to place the leather terminating
the heel; s, metal plate for uniting solidly the sole to the heel by means of
screws. Fig. 3 represents simply the metal heel half open, showing the
opening by which the conducting plate is heated. In Fig. 4 is seen the
metallic plate m heated by the conductability of the metal, causing the heat to
circulate over the entire shoe, and is always constant; t, opening forming a
stop to prevent the plate m being displaced. This system of heating boots
and shoes being thus described, it will be readily understood that great
advantages are derived from it, and more especially in wet weather when the
shoe is always damp.
Having described the nature of the Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by
the berein-before in part recited Letters Patent is, the heating apparatus
applied to boots, and which communicate the heat throughout the sole,
either by means of small metal tubes made in the thickness of the sole, or
by the conductability of the metal sole, as described. Also the employment
of a combustible sole placed between two metallic soles, and burning that

page_text: sole by igniting it, and arranging a suitable draught hole at the front part
of the shoe.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Thirteenth day of June, in the year of our
Lord One thousand eight hundred and sixty.
WILLIAM CLARK. (L.S.)
