PROVISIONAL SPECIFICATION..
Improved Apparatus for Heating Water:
I THOMAS BRADFORD of the Crescent Iron Works Salford in the County of
Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
This invention is designed principally for public baths and steam laundries but
it may also be applied to other similar purposes where a supply of steam is
available..
The object of the invention is to utilize the steam for the purpose of heating
the water or other liquid on its passage from the cold water cistern or other source
of supply to the vessel or place where it is to be used.
The invention, consists of a simple apparatus to be applied to the water supply pipe
and is in, the form of a bollow vessel or chamber having three outlets, one at each end
opposite to each other, and one at or near the centre, and at or near right angles to
the others.
The central.inlet is connected by a pipe to the cold water supply, and one of the
end inlets, is connected by a pipe to the boiler or steam supply.
This pipe will be smaller in diameter than the water supply pipe and it is furnished
with a coned nozzle or, jet which terminates in the interior of the chamber or vessel
about opposite to the centre of the cold water supply pipe.
Both the cold water supply pipe and the steam pipe will be provided with suitable
stop valves or taps.
At the opposite end to the steam inlet (and preferably in a direct line with it) is
the outlet for the hot water which is provided with a pipe leading to the vessel or
place where it.is to be used.
It, will be evident that if the cold water supply valve valve or tap only is opened
cold water will be supplied through the outlet, but by turning, on. the steam jet also
more or less, the steam will mingle with the water as it passes through the chamber,
and heat the water to a greater or less degree, according to the quantity of steam
admitted to mingle.with the water, and. thus by means of my improved apparatus
hot water can be obtained. from a. cold water supply by simply utilizing a jet of
steam.

Improved Apparatus for Heating Water.
1 Thomas BRADFORD of the Crescent Iron Works Salford in the County of
Lancaster Engineer do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention is designed principally for public baths and steam laundries, but
it may also be applied to other similar purposes where a supply of steam is
available.
The object of my said invention is to utilize the steam for the purpose of heating
the water or other liquid on its passage from the cold water cistern or other source
of supply to the vessel or place where it is to be used.

page_text: The nature of my said invention and the manner in which the same is to be per-
formed or carried into practical effect will be readily understood on reference to the
drawing hereunto annexed and the following explanation thereof.
The drawing represents a vertical section taken through about the centre of the
apparatus.
The invention consists of a simple appliance to be connected to the water supply
pipe and is in the form of a hollow vessel or chamber a having three orifices b c and d
one at each end opposite to each other as at b, d, and one at or near the centre as at c,
and at or near right angles to the others.
The central inlet c is connected by a pipe to the cold water supply and one of the
end inlets is connected by a pipe to the boiler or steam supply.
This pipe will be smaller in diameter than the cold water supply pipe and it is
furnished with a coned nozzle or jet e which terminates in the interior of the
vessel or chamber a about opposite to the centre of the cold water supply
pipe c.
Both the cold water supply pipe and the steam pipe will be provided with
suitable stop valves or taps.
At the opposite end to the steam inlet 6 (and preferably in a direct line with it) is
the outlet for the hot water which is provided with a pipe leading to the vessel
or place where it is to be used.
a,
and
It will be evident that if only the cold water supply valve or tap is opened cold
'water will be supplied through the outlet d but by turning on the steam jet also more
or less, the steam will mingle with the water as it passes through the chamber
heat the water to a greater or less degree, according to the quantity of steam admitted
to mingle with the water and thus by means of my improved apparatus hot water
can be obtained from a cold water supply by simply utilizing a jet of steam.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The improved apparatus substantially as hereinbefore described and illustrated by
the drawing annexed for heating water by means of a jet of steam introduced into
the supply pipe between the cold water supply and the hot water outlet.
Dated this 18th day of February 1890.
