IMPROVEMENTS IN GAS STOVES FOR HEATING PURPOSES
Year: 1881

page_text: LETTERS PATENT to Thomas Fletcher, F.C.S., of Warrington, in the County
of Lancaster, for an Invention of "IMPROVEMENTS IN GAS STOVES FOR
HEATING PURPOSES."
PROVISIONAL SPECIFICATION left by the said Thomas Fletcher at the Office
of the Commissioners of Patents on the 6th October 1881.
THOMAS FLETCHER, F.C.S., of Warrington, in the County of Lancaster.
"IMPROVEMENTS IN GAS STOVES FOR HEATING PURPOSES."
This Invention refers to a combination of one or more visible illuminating
flames of gas with a series of tubes or passages which are open at both ends and
so arranged that the heat from the gas flames is communicated to such tubes or
passages and thus induce currents of air to pass through them and in so doing to
become heated.
The outsides of these tubes may be wholly or partially polished and thus
act as reflecting surfaces to the gas flames which burn in front of them but not
in contact.
In some cases, where it is desirable to draw the air from the outside, I arrange
the tubes or passages to be in communication with a closed chamber which receives
its supply of air from the outside.
I thus construct a gas heating stove in which I utilise not only the radiant
heat of visible illuminative flames of gas, assisted by reflecting surfaces, but by
means of the combination with the tubes or passages inducing currents of air to
pass through them and to become heated as aforesaid, I cause the atmosphere of a
room to pass or circulato through the stove and so to become rapidly heated and
kept up to the desired temperaturo.

"IMPROVEMENTS IN GAS STOVES FOR HEATING PURPOSES."
This Invention refers to a combination of one or more visible illuminating
flames of gas with a series of tubes or passages which are open at both ends and so
arranged that the heat from the gas flames is communicated to such tubes or passages
and thus induce currents of air to pass through them and in so doing become
heated. The outsides of these tubes may be wholly or partially polished and thus
act as reflecting surfaces to the gas flames which burn underneath or in front of
them but not in contact.
In some cases where it is desirable to draw the air from the outside I arrange
the tubes or passages to be in communication with a closed chamber which receives
its supply of air from the outside. I thus construct a gas heating stove in which
I utilise not only the direct radiant heat of visible illuminating flames of gas,
assisted by reflecting surfaces or not, as desired, but by means of the combination
with the tubes or passages, inducing currents of air to pass through them and to
become heated as aforesaid, I cause a current of air to pass or circulate
through the stove and so to become rapidly heated and kept up to the desired
temperature.
Having thus particularly described the nature of my said Invention, together
with the best methods with which I am acquainted for carrying the same into
practical effect, I wish it to be understood that what I claim as my Invention and
desire to secure by Letters Patent is,-
The combination of one or more visible illuminating flames of gas with a series
of tubes or passages in the construction of a gas heating stove substantially as
hereinbefore described.
In witness whereof, I, the said Thomas Fletcher, have hereunto set my hand
and seal, this Eleventh day of March, in the year of our Lord One thousand
