Improvements in Apparatus for Supplying Hot or Cold Water in Bath
Rooms, Lavatories, Pantries, and other places.
-
I, MICHAEL MARY BROPHY, of the Firm of James Slater & Co., 251, High
Holborn, in the County of London, Engineers, 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:—
My invention relates to apparatus for supplying hot or cold water for bath-
room, lavatory, domestic and other purposes and to that class of apparatus wherein
both the hot and cold water are delivered through a single nozzle or spout and
wherein the hot water is obtained by introducing more or less steam into the cold
water as the latter is being delivered, the object of my invention being to improve
the construction of this class of apparatus and to provide means whereby it will
be impossible for the steam to be delivered without water.
In the accompanying drawing,—
Figure 1 is a front view of my improved apparatus; and
Figure 2 is a sectional side view of the same;
Figures 3, 4, 5, 6, 7 and 8 are sections on the lines 3-3, 4-4, 5-5, 6-0, 7-7
and 8-8 respectively of Figure 2.
is the stem or standard of the apparatus which is adapted to be held in any
suitable manner, for instance, as shewn in Figure 2, (which represents my
apparatus as applied to a lavatory basin) by providing it with a flange a¹ which
rests upon the lavatory top and a collar which is tightened against the under-
side of the said top through the medium of a sleeve a (as shewn in Figures 1
and 2) the sleeve being provided and the stem being made of extra length to avoid
the inconvenience of having to tighten up the collar a² in a confined space.
b is a heater which is attached to the lower end of the said stem and has
connected to it steam and water inlet pipes c, d respectively and formed in it a
chamber e into which the water and steam which flow through the pipes c, d mix
and which I will hereinafter refer to as the mixing chamber.
f is a twin cock which is mounted upon the upper end of the stem and which
serves to control the admission of steam and water through the pipes c, d.
The said stem, heater and cock have formed in them, by partitions g, passages
as follows, namely, a passage c¹ which extends from the steam pipe c up to the
valve of the cock f and a passage which extends down from the valve h
to the chamber e into which it opens through the port el a passage which
extends from the pipe d up to the valve h¹ in the cock f and the passage which
extends down from the valve to the chamber e, into which it opens, through
the port and the passage i which extends from the top of the chamber e to
the spout j.
:
The port e has connected to it a perforated pipe & (Figures 2 and 7) around which
wire gauze or other suitably perforated material is wound or placed, this
gauze being provided for the purpose of breaking up the steam which enters
the chamber through the perforated pipe and causing it to intermingle with the
water which enters the chamber through the port e without noise.
With the arrangement hereinbefore described it will be understood that when
the valve his opened steam will flow through the steam pipe c, the passages c¹, c²,

page_text: the port e, the perforated pipe k and the wire gauze into the chamber e, and
thence, assuming there is no water in the chamber, through the passage i to the
spout j. If, on the other hand, the cock h¹ is opened water will flow from the
pipe & through the passages d¹, and the port into the chamber e and thence
through the passage i to the spout j.
The cock which is used may be of any desirable construction, in practice,
however, I find it advantageous to make use of cocks of the kind described in
the Specification filed with my application of even date with this Application
No. 12162 wherein the valves h, h¹ are operated by cams m, m¹ respectively, as
shewn in Figures 2 and 3, the said cams being upon spindles n, which are
respectively provided with the operating levers o, o¹.
In order to prevent steam from flowing through the apparatus without water I
cause the adjacent ends of the levers o, o' to overlap, as indicated at p in Figure 1,
the said ends being halved, as shewn at q in Figure 2, so that the handles, when
in their normal position, will be in the same axial line. With this arrangement
it will be obvious that the lever o for admitting steam cannot be moved without
moving the lever ol for admitting water whilst the lever o¹ of the water valve can
be moved independently of the lever o of the steam valve in order to obtain cold
water when desired.
In practice the supply of steam and water to the apparatus should be so
proportioned that when say both valves are fully open hot water will flow through
the spout cooler water being obtainable by more or less shutting off the supply
of steam.
In some cases I provide for obtaining hotter water by arranging the cam
operating the water valve in such a manner that after it has been moved to
'full open a further movement will decrease the flow of water without affecting
the supply of steam.
وو
A great feature of my apparatus is that it is extremely compact and that the
steam and water supply connections and the heater can be absolutely concealed
whilst at the same time the cocks for controlling the supply of steam and water
can be directly operated. .
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. Apparatus for supplying hot and cold water in bath-rooms, lavatorics,
pantries and other places, comprising a stem or column with a steam heater
at the lower end and controlling cocks at the upper end, suitable passages being
formed in the column for conveying the steam and water which are introduced
near the lower end of the column to the top of the said column and thence down
to the heater whence the water, either hot or cold, flows upwards in a passage
in the stem or column to the discharge spout, substantially as described.
2. In apparatus of the kind referred to in the preceding claiming clause a
steam heater consisting of a perforated pipe surrounded by wire gauze or other
suitably perforated material through which the steam has to pass to come into
contact with the water, substantially as, and for the purpose, described.
3. The manufacture and use of the improved apparatus for supplying hot or
cold water in bath-rooms, lavatories, pantries and other places, substantially as
herein before described and illustrated in the accompanying drawing.
