America.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 28th September 1875.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare
the nature of the said Invention for " IMPROVEMENTS IN HEATING APparatus
FOR DOMESTIC AND SIMILAR PURPOSES," a communication, to be as follows:-
This Invention relates to improvements in the class of heaters which
are denominated "French fire logs." These heaters have been con-
structed of terra cotta or clay ware, and have their faces or front sides

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lako in the Great Seal Patent
Office on the 25th March 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-cighth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert
Lake, 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 "IMPROVEMENTS IN HEATING APPARATUS FOR DOMESTIC AND
SIMILAR PURPOSES," a communication to me from abroad by Albert Hale
Mershon, of Philadelphia, Pennsylvania, United States of America,
upon the condition (amongst others) that I, the said William Robert
Lake, my exccutors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and causo
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 Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statomont, reference being had to the accompanying
Drawing forming a part of this Specification:-
This Invention relates to improvements in the class of heaters
which are sometimes donominated "French firo logs." These heaters

page_text: have been constructed of terra cotta or clay ware, and have their faces
or front sides perforated and formed to resemble logs of wood, with
applied splints of asbestos, which become incandescent when in use, so
that when inflammable material is turned into the heaters and ignited at
thic perforations numerous jets are produced which combine in such a
manner as to present the appearance of a wood fire, and the result is a
serviceable, cheerful, and ventilating fire. Now while this idea is
extremely practical and useful the material of which the logs are con-
structed is such that the logs are exceedingly fragile, consume much
material in manufacture, and are thus expensive, require careful
handling, crack with the heat, and do not retain heat, all of which are
serious objections.
This Invention is designed to remedy the aforesaid defects, and con-
sists in forming a heater of a metallic body constructed with a facc
extending from the highest point, which is at or about the back in a
sloping or curved form, so as to present a heating surface on the front
or on the sloping part facing the apartment, and having numerous per-
forations, through which the inflammable material escapes, so that when
ignited it unites or combines and produces a powerful and cheerful fire,
and said faco is formed with curved or angular corrugations, or both, to
increase the heating surface and present an ornamental and attractive
appearance in imitation of a fire of wood, coal, or other fuel.
The said Invention fi
fax nuoducing hot water
consists in combining with the heater

page_text: on the front or on the sloping part facing the apartment in which the
heater is located. This face has numerous perforations C, which afford
means for directing the inflammable material from the body to said face,
where it will be consumed, and said perforations or jets will be made in
various portions of the face, so that when the inflammable material is
ignited it will in burning form a broad flame, thus producing a powerful
heat, which will be retained in the body owing to the nature of the material
of which it is composed, and then thrown into the apartment in a large
volume and to a great distance. Since every part of the body becomes
heated combustion of the inflammable material will be assisted,
inasmuch as the said material is warmed before it escapes at the
into A

page_text: Having thus fully described the said Invention as communicated to
mo by my foreign correspondent, and the manner of performing the
samc, I wish it understood that I claim,—
First. The heater constructed of a metallic body, having a face,
sloping or curved, in connection with perforations and corrugations in
said face, to form a heating surface on the front or toward the apart-
ment, as above set forth and for the purpose specified.
Second. In combination with the said heater the apparatus for
producing hot water and steam, as above set forth.
In witness whereof I, tho said William Robert Lake, have here- 1
unto set my hand and seal, this Twenty-fifth day of March,
in the year of our Lord Onc thousand eight hundred and
seventy-six.
