page_text: LETTERS PATENT to John Bartlett of Mess" Strode and Cos Works,
Osnaburgh Street Regent's Park in the County of Middlesex for an
Invention of "A NEW OR IMPROVED GAS STOVE FOR HEATING WATER FOR
BATHS AND OTHER LIKE PURPOSES,"
PROVISIONAL SPECIFICATION left by the said John Bartlett at the Office
of the Commissioners of Patents on the 7th November 1882.
JOHN BARTLETT of Messrs Strode and C" Works, Osnaburgh Street Regent's
Park in the County of Middlesex "A NEW OR IMPROVED GAS STOVE FOR
HEATING WATER FOR BATHS AND OTHER LIKE PURPOSES"
My invention relates to a compact and simple construction of gas stove for
heating water such as may be required for a bath or like purpose. The body of
the stove, preferably of cylindrical form has a double casing, the annular space
between the inner and outer shells being filled in with material that is a bad
conductor of heat. In the lower part of the casing is fixed a circular grid of gas
jets, and a little way above it is fixed a horizontal pipe coil, or it may be a hollow
grid or set of pipe rings connected together by cross branches. From this coil, grid
or set of rings a number of helically twisted tubes ascend to a shallow receptacle
near the top of the stove, which receptacle is made of a form convex upwards and
has through it a number of holes. From the upper part of the stove above the
receptacle there is a lateral passage to a flue, and from the upper part of the
convexity of the receptacle a pipe leads to the exterior of the stove. The grid of
gas jets at the bottom of the stove has a pipe for gas supply, and the pipe coil,
grid or set of rings above has a pipe for water supply, both pipes being provided
with cocks which are connected together, so that the gas and water are turned on
and off simultaneously. Attached to the common axis of the gas and water.cocks
is a bent branch gas pipe. The jet from this pipe is in the first place lighted
outside the stove, and then on turning the cocks so as to supply the gas and water,
the jet end of the branch pipe is made by the movement of the cocks to pass
through a lateral hole into the interior of the stove where it kindles the gas jets

page_text: issuing from the grid. The hot products of combustion from these jets ascend the
stove and heat the helical tubes, finally passing through the holes in the receptacle
and away to the flue. Meanwhile the water ascending the helical tubes to the
receptacle becomes heated, and is discharged hot by the pipe from the upper part
of the receptacle. When sufficient hot water is thus obtained the cocks are turned !
shutting off the supplies of gas and water and withdrawing the kindling jet from
the interior of the stove. This jet may be supplied by a by-pass from the gas
service, so that it can be left lighted ready for use when the gas and water are
turned off.

My Invention. relates to a compact and simple construction of gas stove for
heating water such as may be required for a bath or like purpose. Fig. 1 is a
vertical section and Fig. 2 a side view of a stove according to my invention. The
body of the stove A, preferably of cylindrical form, has a double casing, the annular
space between the inner and outer shells being filled in with material B that is a
bad conductor of heat. In the lower part of the casing is fixed a circular grid C
of gas jets, and a little way above it is fixed a horizontal pipe coil D, or it may be
a hollow grid or set of pipe rings connected together by cross branches. From this
coil, grid or set of rings a number of helically twisted tubes ascend to a shallow
receptacle near the top of the stove, which receptacle is made of a form convex
upwards and has through it a number of holes. From the upper part of the stove
above the receptacle there-is a lateral passage G to a flue, and from the upper part
of the convexity of the receptacle a pipe leads to the exterior of the stove. The
grid of gas jets C at the bottom of the stove has a pipe I for gas supply, and the
pipe coil, grid or set of rings above has a pipe J for water supply, both pipes being
provided with cocks K and L which are connected together, so that the gas and
water are turned on and off simultaneously. Attached to the common axis of the
gas and water cocks is a bent branch gas pipe M. The jet from this pipe is in the
first place lighted outside the stove, and then on turning the cocks so as to supply
the gas and water, the jet end of the branch pipe is made by the movement of the
cocks to pass through a lateral hole N into the interior of the stove where it
kindles the gas jets issuing from the grid C. The hot products of combustion from
these jets ascend the stove and heat the helical tubes E, finally passing through the
holes in the receptacle F and away to the flue G. Meanwhile the water ascending

the pipe H from the upper part of the receptacle. When sufficient hot water is
thus obtained the cocks K and L are turned, shutting off the supplies of gas and

water and withdrawing the kindling jet M from the interior of the stove.
may be supplied by a by-pass from the gas service, so that it can be left lighted
ready for use when the gas and water are turned off The casing B instead of
being filled with non-conducting material may be a water casing communicating
below with the coil D and above with the receptacle F, or may have a water casing
within it as shown.
Having thus described the nature of my invention and in what manner the saino
is to be performed, I claim:
The herein described construction of gas stove for heating water.
In Witness whereof I the said Jolin Bartlett have hereunto set iny hand
and seal this fifth day of May in the year of our Lord One thousand
eight hundred and eighty three
