PROVISIONAL SPECIFICATION.
Improved Arrangement of Bath and Water Heating Apparatus.
I EDMOND MARIE CHABOCHE, of 95 Boulevard Beaumarchais, Paris in the
Republic of France do hereby declare the nature of this invention to be as
follows:-
This invention consists in a novel arrangement of water heating apparatus and
bath, which presents several important advantages over apparatus of the kind at
present in use.
In carrying out this invention, the water heater is arranged against the wall at
a suitable height, and the bath is arranged to turn up on a hinge, so as to enclose
the water heater, and be out of the way when not required for use.
The bath is provided with a special arrangement of syphon, whereby it may be
readily emptied, the said syphon being connected to a pipe at the level of the floor
in a simple manner.
The fitting up of the apparatus does not require a workman, as the pipes are
connected by the ordinary junctions.
The emptying arrangement consists of a valve in the bottom of the bath,
provided with a rod, on the top of which is a float to raise the valve, should the
water rise too high in the bath. This valve is in connection with a passage which
is formed outside the bath, and rises up nearly to the normal level of the water,
where it is counected with an overflow pipe.
The valve is usually worked by hand.
The heating apparatus will be provided with a chimney, which is arranged
so that it can be raised or otherwise manipulated, to allow the bath to close against
the wall.
Any heating apparatus may of course be employed with the bath arrangement
above described, but I prefer the following:
The apparatus consists of (1) a foyer or fire place, which may be adapted to
burn gas or any other combustible. When gas is used, a burner of the Bunsen
type is used. (2) The heating surface, which consists of a number of tubes
through which the water circulates. These tubes may form one continuous
passage, or may be arranged in groups, the water passing from the upper to the
lower. (3) Of a linen heater, which is heated by the waste gas; and (4) the
distributors.
These distributors consist of a gas-cock provided with a by-pass for lighting the
gas, and both can be operated by hand, in order to regulate and light the gas.
Also of a screw-down water-cock provided with a screw to regulate the exact
amount of water to pass, in order to obtain a specified temperature. The gas and
water cocks or regulators are connected together so that the water and the gas
shall be turned on together. A second water cock is provided, so that the
temperature of the water at the point of issue may be reduced by cold water if
necessary.
A safety apparatus is provided consisting of two diaphragm governors. One is
in connection with the water main, which raises the diaphragm and pushes up a
rod. This rod is connected with a similar rod acted upon by the diaphragm of
the other or gas governor, and if there is a pressure of water, all the pipes are
open. If, however, the water is shut off independently of the governor, the
diaphragms will drop and close the governors; thus, if there is no water, there will
be no gas, and the tubes of the heater will not become burnt.

Improved Arrangement of Bath and Water Heating Apparatus.
I EDMOND MARIE CHABOCHE, of 95 Boulevard Beaumarchais, Paris in the
Republic of France, 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 new system presents, as a whole, many important advantages over
apparatus hitherto known. The principal advantage consists in the arrangement
as a whole, by which all the necessary apparatus is carried by, or attached to, a
vertical table or slab secured to the wall, the heating apparatus and the distributing
apparatus occupying the middle of the table. The bath, suitably hinged or
pivotted, can be placed in the ordinary horizontal position for use, or in the vertical
position after use, so as to enclose the heating and distributing apparatus. In this
manner, the whole apparatus occupies the minimum of space, thus allowing for its
employment in places where the old systems would be rejected for want of room.
A second advantage is derived from the employment of an elastic syphon for
emptying the bath. This syphon, once charged, empties the whole of the water
of the bath. It is only necessary to join it by a pipe, at the level of the floor, to
any kind of discharging apparatus, thus suppressing gutters, sinks, basins, &c.
A third advantage is, that there is no necessity to employ a special workman to
put the apparatus in position, since it is sufficient to connect the pipes by
junctions.
To render more clear the explanations which will now follow, I have represented,
by way of example, in the drawings annexed, my new system of bath arrangement,
that is to say :-
Fig. 1 is a view shewing the bath in its vertical or raised position, Fig. 2
representing it in a horizontal position;
Fig. 3 is a front view, with the bath horizontal;
Fig. 4 represents the safety apparatus ;
Fig. 5 is a detail of the gas burner;
Fig. 6 is a gauge tap;
Fig. 7 is a detail of the gas tap.
The bath, of copper, zinc, or other material has a form which may be varied.
At the foot of the bath is placed the emptying apparatus. The normal level of the
water (not comprising the displacement of the water caused by the bather) is at N N.
V is the valve (Fig. 2), which, on rising, permits the water to run away. T is a
valve or lifting rod, and M a handle. F is a float, the office of which is to open
the valve V automatically, when the bath is about to overflow. The lifting
rod T can be maintained in a raised position by any convenient means while the
bath is emptying. The water runs out through the passage S S', and at S₁ a
flexible junction piece S" provides for the connection of the part S¹ to the pipe S",
by which the water passes before entering the syphon S i.
The elastic pipe can be replaced by any suitable junction that will fulfil the
same end. With this arrangement, the bath can be turned around the said junc-
tion at S¹. If a flexible pipe is employed, the bath, which will be carried by one
or two brackets, will turn on an axis O, being assisted in this operation by counter-
balance weights or springs.
As the heating apparatus necessarily carries, at its upper part, an escape flue
for the products of combustion, it will be necessary to divide the flue, so as to
allow of the passage of the edge of the bath, when it is turned up, as indicated at
Fig. 1. At Fig. 2 is represented a means of effecting this division.
It will be understood that any other arrangements which permit such separation
or division may be used.
G is a sleeve which slides longitudinally on the escape flue, and rests on a ferrule

page_text: or socket when the bath is down. If it is desired to raise the bath to a vertical
position, the sleeve G is raised by means of the lever Land the rod P. A collar B
(or bracket) secured to the table or slab supports and guides the upper part of the
flue.
The bath, when in its vertical position, covers in the whole of the heating
apparatus, which may be of any desired system, as before mentioned.
I will now describe an arrangement of heating apparatus which I prefer to
employ; it is divisible into 4 parts, viz. :-(1) the furnace, (II) the heating sur-
face; (III) the drying stove; (IV) the distributing apparatus.
(I). The furnace burns illuminating gas, but may be arranged to burn any other
combustible, as may be desired, either liquid, solid, or gaseous. The gas enters by
a distributing tap a, and passes into a general passage d, which divides into 4
distinct passages d', d², d³, d. Each passage feeds a certain number of burners of
conical form (see enlarged detached view Fig. 5), surmounted by a chimney d*,
which receives at its lower part the gas and air, which mix in it, combustion
taking place at the upper part, like a Bunsen burner.
(II). This surface of the heater S C is composed of horizontal tubes of thin
copper or other metal fixed at each extremity in the tube plates p p. On the tube
plates are fixed plates q 9, which, by means of baffle plates, force the water to enter
one or more tubes at a time, and not to leave, except after having run through the
whole of the tubes, either singly or in groups. The water enters cold at one end,
and leaves hot at the other. The quicker the water passes, the less it will be
heated.
(III). The drying stove for linen is arranged above the heating surface; it is
heated by the waste heat of the gases of combustion. It may be made of any
material, and lined with pottery or earthenware, glazed.
(IV). The distributors are:-(a) A gas tap a for the general supply (Fig. 7) of
the burners. This tap is locked by the action of the by-pass tap, which serves as a
lighter. This by-pass tap consists of a socket or barrel a¹ attached to the side of
the gas pipe, and containing a plug a², carrying at its upper part a handle a³ and
hollow rod a', serving as a conduit for the gas of the lighter. Between the plug a
and the handle a³ is a tap a³ to shut off the by-pass gas supply. When the
apparatus is not in use, the end of the lighter a is in front and the plug locked, the
large tap a being itself locked by the projecting lug a carried by the small tap a³.
The action consists, 1st, in opening the small tap a, and lighting the lighter a.
This unlocks the plug a², which can be turned by the handle a³; the plug puts the
lighter in place, and, in consequence of this movement, the large tap a is left free.-
(b) A quarter-turn water-gauge cock on the pipe L, provided with a pressure
valve, carries, at its upper part, a gauging screw and a locking nut ³. The
screw has for its object to allow only such a quantity of water to pass, as can be
readily brought to a high temperature of, say, from 60 to 90° centigrade. The
water tap and the gas tap a are enabled to act at the same time by the addition of
the two arms * a*, attached to a connecting rod, (see Fig. 3), so that when the gas
cock a is opened, the water tap 1 will be opened to an equal amount.-(c) a second
water tap m permits of increasing, by hand, the supply of water, in order to
diminish the temperature at the outlet. These two water taps / and m are con-
nected, on the one part, to the general water supply from the main, and on the
other, to the pipe L, which conducts the water to the surface of the heater S C.
From this heating surface, the water runs into the bath by rr'. The safety
apparatus S S¹, Fig. 4, will now be explained. It is composed of two chambers.
Each chamber is divided internally into two parts by an elastic diaphragm. The
chamber a of the first apparatus, is put in communication with the water of the
main which is under pressure. The diaphragm subjected to such pressure of water
expands against the wall p, and carries with it, in its movement, the rod t. The
rod t¹, which is connected with the rod t, follows this movement, and raises with it
the elastic diaphragm of the second receptacle or chamber 6**.
The gas, before arriving at the large tap a, passes through the chamber 6** of

page_text: this receptacle. In the position shown, it will pass freely. On the contrary, if the
water has not sufficient pressure, that is to say, if, independently of the apparatus,
the water is stopped, the arrangement of rods t t' will fall by its own weight or by a
spring, and, in that way, cut off, by the aid of the movable diaphragm, the com-
munication of gas through the chamber 6**. Thus, if there is no water, there is no
gas, or, on the contrary, both water and gas. This apparatus prevents the heating
of the tubes when there is no water, an operation which is dangerous to the
preservation of the apparatus.
It will be evident that any suitable arrangement of apparatus for applying a
douche may be added if desired.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of parts consisting of a vertical table which carries, at its
middle, the heating apparatus and its accessories, as well as the supports for the
bath which permit the change of position of the bath from the horizontal to
the vertical position, counterweights or springs being provided to assist this
movement.
2. A heating apparatus consisting of the gas furnace, the heating surface per-
mitting the instantaneous heating of the water by its circulation in the tubes, or in
the groups of tubes, with or without the drying stove placed above the heating
surface.
.
3. The arrangement of the taps and distributing apparatus, as well as the means
for automatically cutting off the gas, as above described.
4. The combination with the improved arrangement of bath, of any kind of
apparatus for applying a douche.
