PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Water by Means of Steam.
I, JAMES HORN PYLE, of 38, Elliot Street, in the County of Glasgow, North
Britain, Coppersmith, do hereby declare the nature of this invention to be as
follows, that is to say:
My said invention has for its object the constructing of water-heating apparatus
in an improved and simple manner, and so as to be conveniently applicable in con-
nection with baths and the like in steamships and in other situations where steam
is available.
My improved apparatus comprises a vertical cylindrical metal shell having within
it a helically coiled pipe through which the steam passes in a downward direction.
At the bottom of the chamber there is formed an annular space into which the
water to be heated is admitted through an inlet pipe provided with a stopcock. The top
of the annular space has a circular series of holes formed in it directly below the
bottom of the coiled pipe, to distribute the water, which flows up outside and inside
of that pipe. Within the coiled pipe there is a central vertical open-topped tube
the bottom end of which is connected to the pipe or pipes which lead the heated
water to the bath or other vessel. The water in ascending becomes heated by its
contact with the coiled pipe through which the steam passes, and overflows into the
central vertical tube. The apparatus is by preference made for the most part of
copper, but any other suitable metal may be employed.
Dated this Sixteenth day of April 1897.

Improvements in Apparatus for Heating Water by Means of Steam.
I, JAMES HORN PYLE, of 38, Elliot Street, in the County of Glasgow, North
Britain, Coppersmith, 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, that is to say: -
My said invention has for its object the construction of water-heating apparatus,
in an improved and simple manner, and so as to be conveniently applicable in
connection with baths and the like in steamships and in other situations where
steam is available.
And in order that my said invention and the manner of performing the same

page_text: may be properly understood, I hereunto append a sheet of explanatory drawings
showing my improved water-heating apparatus.
Figures, 1, and 2, of the drawings are vertical and horizontal sections of the
apparatus. In these drawings the same reference letters are used to mark the
same or like parts wherever they are repeated.
My improved apparatus comprises a vertical cylindrical metal shell, A, having
within it á helically coiled pipe, B, through which the steam passes in a downward
direction a stop valve, J, being provided for controlling the steam admission to the
pipe. At the bottom of the chamber, A, there is formed an annular space, C, into
which the water to be heated is admitted through an inlet pipe, D, provided with a
stopcock. The top plate or shell, K; of the annular space; C, has a circular series
of holès, E, forined in it, directly below the bottom of the pipe coil, B; to, distribute
the water which flows up outside and inside of that coil. Within the coil, B,
there is a central vertical open-topped tube G, the bottom end of which is con-
nected to the pipe, H, which leads the heated water to 'the bath or other vessel.
The water in ascending becomes heated by its contact with the coiled steam pipe, B,
and overflows into the central vertical tube, G. The apparatus is by preference
made for the most part of copper but any other suitable metal may be, employed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
.11. 1.- :
Apparatus for heating water by means of steam; comprising a vertical cylindrical
metal vessel having within it a helically coiled steam pipe, a vertical open-topped
tube, and an annular space, covered by a shell having a series of holes formed in
it, substantially as hereinbefore described and as shown in the accompanying
drawings.
