PROVISIONAL SPECIFICATION.
Improvements in and connected with Baths.
I, JOHN SHANKS, of the Tubal Works, Barrhead, in the County of Renfrew,
North Britain, Sanitary Engineer, do hereby declare the nature of this Invention
to be as follows, that is to say:-
My said Invention comprises improved heating apparatus and improved dis-
charge apparatus for baths.
The improved heating apparatus is designed for use in cases in which steam is
available. A tube is arranged immediately under the bottom of the bath, along
the middle or at any other convenient part, this tube communicating with the
interior of the bath by two openings one or both of which serve as discharge outlet
or outlets to the bath. One end of the tube communicates with the discharge
passage in which there may be any suitable known arrangement of discharge plug
or valve. The other end of the tube has connected to it a steam supply pipe, and
in one modification the steam pipe extends a suitable distance within the tube and
has an open end through which the steam issues. The steam thus issuing heats
the water and at the same time causes it to circulate through the bath and tube so
as to speedily produce a uniform temperature. In another modification the steam
does not mix with the water, the steam pipe within the tube being enclosed in a
larger pipe with a closed end, and provided with an outlet for water due to
condensation.
The improved discharge apparatus which may be combined with the heating
apparatus hereinbefore described or fitted to any bath consists of a siphon the
short leg of which is made with a shallow trap bend at its lower end whilst its
upper end is at about the overflow level. The long leg is preferably made with a
bulb-like enlargement at its lower part. For starting the siphonal discharge
action a small nozzle directed upwards is inserted at the bottom of the short leg,
and steam or water under pressure is supplied to it through a stop valve, so as by
the jet action to cause an upward flow in the short leg.

COMPLETE SPECIFICATION.
Improvements in and connected with Baths.
I, JOHN SHANKS, of the Tubal Works, Barrhead, in the County of Renfrew,
North Britain, Sanitary 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, that is to say:-
My said Invention comprises improved heating apparatus and improved dis-
charge apparatus for baths.

page_text: The improved heating apparatus is designed for use in cases in which steam
is available. A tube is arranged to communicate at two points with the interior
of the bath. This tube has connected to it a steam supply pipe with an open end
through which the steam issues thus heating the water and causing it to circulate.
Or the steam pipe within the tube may be enclosed in a larger pipe with a
closed end.
The improved discharge apparatus consists of ja, siphon the short leg of which is
made with a shallow trap, bend at its lower end. For starting the siphonal dis-
charge action a small nozzle directed 'upwards is inserted at the bottom of the
short leg, and steam, or water under pressure, is supplied to it so as by the jet
action to cause an upward flow' in the short-leg
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and showing several modifications of my improvements.
Figures, 1, and 2, on the drawings are longitudinal vertical sections showing
two modifications of a bath provided with my improved lieating apparatus.
Figures, 3, and 4, are perspective views showing two modifications of details of
the heating apparatus, and Figure, 5, is a longitudinal vertical section showing a
bath provided with my improved discharge apparatus combined with the modifica-
tion of heating apparatus shown in Figure,. 1.. In these drawings. the same
reference letters are used to mark the same or like parts wherever they. are
repeated.

The improved heating apparatus is designed for use in cases in which steam is
available. As shown in Figure, 1, a tube, A, is arranged immediately under the
bottom of the bath, B, along the middle, (or it might be at any other convenient
part) this tube, A, communicating with the interior of the bath, B, by two
openings, C, D, which serve as discharge outlets to the bath. One end of the
tube, A, communicates with the discharge passage, E in which is shown a well
known form of discharge plug or valve, G. The other end of the tube, A, has
connected to it a steam supply pipe; II, which extends a suitable distance within
the tube and has an open end through which the steam issues. The steam thus
issuing heats the water and at the same time causes it to circulate through the
bath, B, and tube, A, so as to speedily produce a uniform temperature in the water
in the bath..
"
In the modification shown in Figure, 2, the steam does not mix with the water,
the steam pipe, If; within the tube, A, being enclosed in a larger pipe, J,
with a
closed end, and provided with an outlet, K, for water due to condensation.
The modification shown in Figures, 3 and 4 correspond respectively to the
modifications shown in Figures, 1, and 2, except that one end of the tube, A, is
not connected with the discharge passage, E, a separate outlet (not shown) froín
the bath being provided in these modifications!
The improved discharge apparatus is shown in Figure, 5, as combined with the
heating apparatus hereinbefore described with reference to Figure, 1, or it may be
fitted to any bath;, and consists of a siphon the short leg, L, of which is made with
a shallow trap bend, M, at its lower end whilst its upper end is at about the over-
flow level. The long leg, N, is preferably made with a bulb-like enlargement, P,
at its lower part. For starting the siphonal discharge action a small nozzle, Q,
directed upwards is inserted at the bottom of the short leg, L, and steam or water
under pressure is supplied to it through a stop valve, R., so as by the jet action to
cause an upward flow in the short leg.b
וי
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: ;
་། '
1. In heating apparatus for baths arranging a tube so as to communicate with
the interior of the bath by two openings and having projecting into it a-steam

page_text: supply pipe which may be open-ended or enclosed in a larger pipe with a closed
end substantially as and for the purposes hereinbefore described.
2. In discharge apparatus for baths providing a siphon the short leg of which is
made with a trap bend at its bottom and has inserted into it a nozzle directed
upwards to which steam, or water under pressure is supplied substantially as and
for the purpose hereinbefore described and as shown in Figure, 5, of the accom-
panying drawing.
