Year: 1859

page_text: LETTERS PATENT to James Hill Hume, of Broughty Ferry, in the County
of Forfar, North Britain, Baker, for the Invention of "IMPROVEMENTS IN
WARMING APPARATUS FOR THE FEET."
Sealed the 19th July 1859, and dated the 21st January 1859.
PROVISIONAL SPECIFICATION left by the said James Hill Hume at
the Office of the Commissioners of Patents, with his Petition, on the
21st January 1859.
I, JAMES HILL HUME, of Broughty Ferry, in the County of Forfar, North
Britain, Baker, do hereby declare the nature of the said Invention of
"IMPROVEMENTS IN WARMING APPARATUS FOR THE FEET," to be as follows, that
is to say:-
This Invention relates to the arrangement and construction of a simple
portable apparatus capable of being worn on or attached to the feet, so as to
warm them when travelling, and in other circumstances. The apparatus
consists of a metal case or shallow chamber attached to the sole of the boot or
shoe, and having one of its sides capable of being opened and closed with a
spring fastener. This metal chamber has fitted within it a sole, piece of brick,
fire-clay, or other available material, which when inserted in its place for use,

page_text: is heated. This apparatus or "foot comforter" is so formed as to be an exact
fit to the sole of the boot or shoe to which it is attached, so as to resemble a
double sole; it is attached by means of an elastic toe-piece and a similar piece
for the heel, both being attached to the heater case.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Hill Hume in the Great Seal Patent Office on the
20th July 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HILL HUME, of Broughty Ferry, in the County of Forfor, North Britain,
Baker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of January, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Hill Hume, Her special licence that I, the said James
Hill Hume, my executors, administrators, and assigns, or such others as
I, the said James Hill Hume, my executors, administrators, and assigns;
should at any time agree with, and no others, from time to tiine 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
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN WARMING APPARATUS FOR THE FEET," upon the condition
(amongst others) that I, the said James Hill Hume, 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 Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said James Hill Hume, do hereby declare
the nature of my said 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 the arrangement and construction of a simplė
portable apparatus capable of being worn upon or attached to the feet, so as to

page_text: warm them when travelling, and in other circumstances.
The apparatus
consists of a metal case or shallow chamber to be attached beneath the sole of
the boot or shoe, and having one of its sides capable of being opened and
closed. This metal chamber has fitted within it a sole piece of brick, fire-clay,
or other available material, which is inserted in its place for use in a heated
state. This apparatus or "foot comforter" is formed so as to fit the sole of
the boot or shoe to which it is to be attached, and to resemble a double sole;
it is attached by means of an elastic or other toe-piece and a similar piece for
the heel, both pieces being attached to the heater case.
The manner in which my said Invention may be carried into effect, will be
clearly understood on reference to the accompanying Sheet of Drawings,
Fig. 1 of which represents a longitudinal section through the central line of a
foot-warmer constructed according thereto; Fig. 2, a plan or view of the same
from above; and Fig. 3, a transverse section thereof. a represents a shallow
case or chamber, constructed of tin or other suitable material, formed to fit the
sole of a boot or shoe, and containing the fire-clay or other sole or heater b,
resting upon the felt or other non-conducting lining c interposed between it
and the bottom of the case a. The upper side or plate d of the chamber a is
loose (so as to be capable of being removed to allow the introduction of the
fire-clay or other sole or heater 6), and is perforated for the purpose of thereby
allowing the more ready passage of heat upward to the foot. e and f are
respectively a toe and heel piece, formed of elastic or flexible material for the
purpose of holding the warmer upon the boot or shoe, to which the whole is
made thoroughly secure by the strap and buckle g, h, or otherwise, as may be
found convenient. The heel part i of the warmer is attached to the other
portion thereof by a hingej or other joint.
"
For the greater convenience of heating the fire-clay or other "heater soles
used in connection with my Invention, I should suggest the employment of a
small portable apparatus similar to that shown at Figs. 4 and 5, the first of
which Figures represents a longitudinal vertical section, and the latter a plan
(having the top part or plate removed) of a box or case k, formed in two
portions capable of sliding one into the other, so as thereby, when not in use,
to occupy little more than half the space occupied by them when drawn out,
as shewn. The two portions of the case are divided horizontally by a shelf or
diaphragm of wire gauze, upon which the fire-clay soles are placed, and are
then heated for use by means of a spirit lamp m, placed beneath the
diaphragm.
Having now described the nature of my said Invention, and in what

page_text: manner the same may be performed, I would have it distinctly understood
that I do not limit myself to the precise details represented, but that I claim
as of my Invention, the general construction of the apparatus for warming the
feet; as herein described.
In witness whereof, I, the said James Hill Hume, have hereto set 5
my hand and seal, this Eighteenth day of July, in the year of our
Lord One thousand eight hundred and fifty-nine.
JAMES HILL (L.S.) HUME.
