IMPROVEMENTS IN GAS APPARATUS FOR HEATING WATER OR OTHER LIQUIDS
Year: 1877

page_text: LETTERS PATENT to William Puckett, of Marlborough Street, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN GAS APPARATUS
FOR HEATING WATER OR OTHER LIQUIDS."
Sealed the 30th November 1877, and dated the 23rd June 1877.
PROVISIONAL SPECIFICATION left by the said William Puckett at the Office
of the Commissioners of Patents on the 23rd June 1877.
WILLIAM PUCKETT, of Marlborough Street, in the County of Middlesex.
"IMPROVEMENTS IN GAS APPARATUS FOR HEATING WATER OR OTHER LIQUIDS."
This Invention has for its object the construction of an apparatus for the more
economical and convenient heating of water in baths or for heating other liquids,
and for other purposes, by submerging a number of gas burners contained within a
suitable case,
than is at present generally employed.
The apparatus consists of either a flat, cylindrical, rectangular, or other suitably
shaped metallic case containing a number of tubes. Of whatever form the case may
be, the tubes, which are open at both ends, are fixed either horizontally or inclined.
There may also be additional tubes fixed above those just mentioned, either
parallel thereto or at right angles to the same. Within the case is a shallow
atmospheric air and gas burner provided with a number of holes proportionate in
size to the quantity of gas to be consumed within a given time.
The burner is connected to a vertical tube having one or more slots cut in it,
the tube being furnished with a sleeve, which may be drawn up or pushed down,
so as to close or open the slots which admit air, and thus produce the proper
mixture.
The gas is admitted by a pipe connected to an ordinary fitting, and descends to a
distance corresponding to the slots in the tube before mentioned, which, together
with the gas pipe, is enclosed in an outer tube that rises above the level of the water
or other liquid to be heated. Within this tube a lighted taper or match may be
introduced whenever it is desired to light the gas.

page_text: In the top of the case is fixed one or more outlets, which rise above the surface of
the liquid, and from which the products of combustion may escape.
The apparatus may also be furnished with a handle for the more convenient
lifting of it.
Whatever form the case assumes it will be necessary to have the apparatus
weighted, so as to ensure its remaining submerged when placed in the water.
The action is as follows:-The sleeve is pulled up, so as to close the slots, the
apparatus placed in the water and the gas then lighted; the sleeve is now thrust
down so as to open the slots, and allow of a mixture being formed and consumed at
the burner. The heat imparted causes a circulation of water through the tubes,
the hot water ascending through the top of each tube, while the cooler water rushes
in at the bottom and supplies its place. Thus a continuous circulation of water is
produced until the water has attained the required temperature, when the sleeve
inay be drawn up, the gas shut off, and the apparatus removed from the liquid.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Puckett in the Great Seal Patent Office on the 14th December
1877.

PROVEMENTS IN GAS APPARATUS FOR HEATING WATER OR OTHER LIQUIDS."
This Invention has for its object the construction of an apparatus for the more
economical and convenient heating of water in baths or for heating other liquids,
and for other purposes, by submerging a gas burner enclosed within a suitable case,
than is at present generally employed.
The apparatus consists of a rectangular shaped metallic case containing a number
of tubes, which are open at both ends, fixed in an inclined position, also a shaft at
each end to admit air in the bottom of the apparatus to assist combustion, also a shaft at
the top for the escape of the products of combustion, these three shafts rising above
the level of the water or other liquid to be heated. Within the case is a shallow
atmospheric air and gas burner provided with a number of holes proportionate in
size to the quantity of gas to be consumed, the bottom of the burner forming the
bottom of the apparatus.
The burner is connected to a vertical tube having two slots cut in it, the tube
being furnished with a sleeve, which may be drawn up or pushed down, so as to
close or open the slots which admit air, and thus produce the proper mixture.
The gas is admitted by a pipe connected to an ordinary fitting, and descends to
a distance corresponding to the slots in the tube before mentioned, which together
with the gas pipe is enclosed in a shaft that rises above the level of the water,
similar to the air shafts before mentioned.
The apparatus for convenience can be inade in any form or size.
Whatever form the case assumes, it will be necessary to have the apparatus
weighted, so as to ensure its remaining submerged when placed in the water.
The action is as follows:-The sleeve is pulled up, so as to close the slots, the appa-
ratus placed in the water, and the gas then lighted by putting a lighted paper or match
down the air shaft adjoining the gas shaft; the sleeve is now pushed down, so as to
open the slots and allow of a mixture being formed and consumed at the burner. The
heat imparted causes a circulation of water through the tubes, the hot water ascending

page_text: through the top of each tube, while the cooler rushes in at the bottom and supplies
its places. Thus a continuous circulation of water is produced until the water has
attained the required temperature, when the sleeve may be drawn up, the gas shut
off, and the apparatus removed from the liquid.
In witness, I, the said William Puckett, have hereunto set my hand and seal,
this Fourteenth day of December, in the year of our Lord One thousand
eight hundred and seventy-seven.
