PROVISIONAL SPECIFICATION.
An Improved Apparatus for Heating the Water in Baths and
the like.
I WILLIAM HARKER of 7 East Street, Drypool, Hull in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to make a simple construction of apparatus for
placing in baths and the like for the purpose of heating the water without the
necessity of employing a hot water cistern.
I construct my invention as follows:--I employ a heating chamber either round,
square or any suitable shape and made of any suitable metal or material, this
chamber is provided with a burner also of any suitable shape running round or
through it, as desired, inside, this burner projects outside the heating chamber
where it has a threaded or rough end to which an ordinary rubber tube is fitted, the
other end of such tube being fixed to an ordinary gas bracket or the like.
Through the heating chamber I pass or form suitable tubes for the water to
circulate through, any suitable number of these tubes may be vertical through the
chamber, and some of them may be diagonal or set at any desired angle, the water
circulates through these tubes and becomes heated.
To the outside of the heating chamber I attach two funnels, one of these funnels
allows of air being admitted into the chamber for the purpose of burning with the
gas and thus helping combustion, the second funnel is employed for the purpose of
carrying off any fumes resulting from the burning of gas within such heating
chamber. Between these two funnels I employ a stay which also serves as a
handle for lifting the heater by. A hole having an air and water tight cap
formed in the heater to allow of a lighted taper or the like being inserte to light
the gas inside.

may weight the heater by attaching two pieces of wire or the like bent inward
at the bottoin, on the projections thus formed by bending 1 slide a flat weight of
auy suitable metal, this weight also forming a stand for the apparatus to rest
upon.
The action is as follows:- -When the water is required to be heated, the tube is
affixed to the burner and the gas lighted inside the heater, the watertight cap is
screwed on and the heater is then placed in the bath into which a suitable quantity
of water has been run, the heater being weighted for the purpose of keeping it
below the water, the water then circulates through the tubes in the heater, and
around it, becoming quickly heated, air being admitted through one of the funnels
to help combustion, and the fumes escaping through the second funnel which may
be continued to an outer wall if desired for the purpose of carrying off such
fumes.
When the water is sufficiently hot the heater
first being turned off.

DESCRIPTION OF DRAWINGS.
Fig. 1. shews an elevation of round or conical apparatus for heating bath water
or the like.
Fig. 2. is a plan of Fig. 1.
Fig. 3. shews front elevation of oblong heater.
Fig. 4. shews end elevation of Fig. 3.
Fig. 5. is plan of Fig. 3.
Fig. 6. shews baffle plate attached to tube of burner.
I construct my invention as follows:-In Figs. 1 and 2, 1 employ a heating
chamber A either round square or of any suitable shape, and made of any suitable
metal or material, this chamber is provided with a burner B, also of any suitable
shape, running round or through it as desired, inside, this burner projects outside
the heating chamber where it has a threaded or rough end to which an ordinary
rubber tube C is fitted, the other end of such tube being fixed to an ordinary gas
bracket or the like.
Through the heating chamber pass or form suitable tubes D for the water
to circulate through, any suitable number of these tubes may be vertical, through
the chamber, and some of them may be diagonal or set at any desired angle, the
water circulates through these tubes and becomes heated.
To the outside of the heating chamber A 1 attach two funnels, one of these
funnels E allows of air being admitted into the chamber for the purpose of burning
with the gas and thus helping combustion, the second funnel is employed for the
purpose of carrying off any fumes resulting from the burning of the gas within such
heating chamber. Between these two funnels I employ a stay G which also serves
as a handle for lifting the heater by.
A hole having an air and watertight cap II is formed in the heater to allow of a
lighted taper or the like being inserted to light the gas inside.
I may weight the henter by attaching two pieces of wire or the like bent
inward on the bottom, on the projections thus formed by bending, I slide a flat
weight of any suitable metal, this weight also forming a stand for the apparatus to
rest upon.
I construct the square or oblong heaters, see Figs. 3. 4. and 5, preferably with
two burners B 13 inside, with a forked pipe connected to each burner, two
funnels E. E. being employed, one for each burner, a branch of gas pipe running
down each funnel, T joint connects the two branches, and the indiarubber tube C
is fitted to the said T joint; also for carrying off any fumes I may employ two
funnels F preferably one over each burner. 1 may also employ a funnel in front
of the heater for admitting air to the chamber A. for combustion purposes, the
funnels E. E. being for the same purpose.
On the tubes of the burners B B, I attach baffle plates B B (see Fig. 6,) one
to ench tube, these baffle plates are soldered or otherwise fixed in the holes in
which the funnels E. E. fit and are for the purpose of allowing air in the tubes

page_text: to pass to the burner, the plates being cut away at the bottom, the air passes
through the hole thus formed, and into the recesses on the underside of the burner
tubes where it passes direct to the burner, it there mixes with the gas and is burut
up thus helping combustion, it also prevents the flame burning back into the burner
tube.
In place of employing a hole with watertight cap I may employ a small lighting
tube H on the top of the chamber A down which a lighted taper or the like is
passed when lighting the gas.
I preferably employ handles G', G, see Figs. 3. 4 and 5. in place of the stay G
shown on the circular heater in Figs. 1 and 2.
The action is as follows:-
-
When the water in the bath is required to be heated,
the tube C is affixed to the burner B and the gas lighted inside the heater which is
then placed inside the bath or the like into which a suitable quantity of water has
been run, or placed the water then circulates through the tubes in the heater and
round it, becoming quickly heated, air being admitted through the funnel or
funnels E. E. to help combustion, the fumes escape through the funnels F. F.
which may be continued to an outer wall or other convenient position for the
purpose of carrying off such fumes.
When the water is sufficiently hot the heater is taken out of the bath or the like,
the gas being first turned off.
The funnels are made sufficiently high for their tops to be above the water when
in usc.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
"
An apparatus for heating bath water and the like, consisting of a heating
chamber A fitted with burner or burners B, gas admitting pipe or tube C, circulating
tubes D, funnels E, E, and J, funnels F, F, for carrying off fumes, baffle plates B³,
and lighting funnel H, substantially as shown and described.
