AN IMPROVEMENT IN STOVES OR APPARATUSES HEATING BY GAS:
Year: 1878

page_text: LETTERS PATENT to William Edward Gedge, of No. 11, Wellington Street,
Strand, London, in the County of Middlesex, Patent Agent, for the Invention
of "AN IMPROVEMENT IN STOVES OR APPARATUSES HEATING BY GAS:" A
communication from abroad by Louis Clément Liotard, of Paris, France.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge at
the Office of the Commissioners of Patents on the 2nd September 1878.
WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand, London, in the
County of Middlesex, Patent Agent. "AN IMPROVEMENT IN STOVES OR APPA-
RATUSES HEATING BY GAS,"
A communication from abroad by Louis Clément
Liotard, of Paris, France.
This Invention relates to the application to gas stoves or heaters for kitchen or
other use of a reservoir or boiler for water or other liquid so combined therewith
as to utilize by circular radiation the heat usually wasted in the gas heaters hitherto
employed, in which no successful attempt has been made to utilize the excess of
heat produced by apparatus heated by lighting gas, either for culinary or manu-
facturing purposes.
As will be seen on reference to the accompanying Sheet of Drawing, this problem
of the utilization of the excess of heat produced by the burners on the performance
of their ordinary work is realized by this Invention, whereby the simplest cooking
apparatus or heater may be provided with a boiler, in which any kind of liquid
may be heated by the heat which now escapes, and is lost during the cooking of
food without increasing the consumption of gas.
On the Drawing Figure 1 is an elevation of a gas stove embodying this Inven-
tion; Figure 2 is a plan of same; Figure 3, a section at A, B; and Figure 4, a
section at C, D.
a, water; b, tap; c, fire-place; d, evaporation tubo; e, circular plates, rings, or
washers.

In the Drawing Figure 1 is an elevation of a gas stove embodying this Inven-
tion; Figure 2 is a plan of same; Figuro 3, a section at A, B; and Figure 4, n
section at C, D.
a, water; b, tap; c, fire-place; d, evaporation tube; e, circular plates, rings, or
washers.
Having now described and ascertained the nature of the Invention communicated
to me as aforesaid, and in what manner the same is or may be performed, I desire
it to be understood that I do not confine myself to any particular shape of reservoir
or boiler, nor to the use of any particular material in its manufacture, and that
what I claim as the Invention secured to me by the herein-before in part recited
Letters Patent is, the utilization of the waste heat from stoves or apparatuses heating
by gas to beat a liquid of any kind, substantially as herein-before set forth, and
illustrated on the accompanying Sheet of Drawing.
In witness whereof, I, the said William Edward Gedge, have hereunto set
my hand and seal, this Twenty-eighth day of February, in the year of our
Lord One thousand eight hundred and seventy-nine.
