We, JAMES MILLER, Mason, of 4 Seamour Street, and CHARLES CAMERON,
Plumber, of 219 Cambridge Street, both places in Glasgow, in the County of
Lanark, North Britain, do hereby declare the nature of our said invention for
"IMPROVEMENTS IN OR CONNECTED WITH WASH HOUSE BINS OR BOXES AND IN
FLUSHING DRAINS," to be as follows, that is to say :-.
Our said Invention has. for its object to utilise the water used in wash houses for
effectually flushing drains connected with dwelling houses and other buildings.
For this purpose we place beneath or in connection with each washing bin or set
of washing bins or boxes such as are usually employed in wash houses connected
with dwelling houses, one or more tanks which will hold several times the contents
of such bin or bins; and in a convenient part of such tank or tanks or in connection
therewith we fit a siphon communicating with the drain pipe. The siphon is placed
with its highest part a little lower than the top of the tank, and so that the water
in the tank does not cover it until the tank is nearly full. With this arrangement
the used water discharged from the washing bin or bins does not pass directly into
the drain pipe, but the successive portions are received into and accumulate in the
tank or tanks until there is sufficient to cover the top of the siphon. Every time
the tank or tanks become filled the water begins to pass off by the siphon and as
the entering leg of the siphon dips down nearly to the bottom of the tank or tanks,
when once the water begins to pass off its discharge continues until the tank or
tanks become nearly emptied. In this way instead of only comparatively small
quantities of water passing into the drain pipe without much flushing action, there
will be fewer discharges into the drain pipe, but each of such discharges will consist
of a large quantity of water and will have an efficient flushing action. Also, besides
the mere flushing action the large quantity of water thus passed at once into the
drain pipe will produce a sucking action which will tend to down fresh air into
the drain pipe and into the various branch waste pipes and soil pipes connected
with it, whilst preventing the passage of sewer gases into such waste pipes and soil
pipes.
The tanks may be made of any suitable material but we prefer to make them of
earthenware.

We, JAMES MILLER, Mason, of 4 Seamour Street, and CHARLES CAMERON,
Plumber, of 219 Cambridge Street, both places in Glasgow, in the County of
Lanark, North Britain, 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 :-
Our said Invention has for its object to utilise the water used in wash houses for
effectually flushing drains connected with dwelling houses and other buildings.
For this purpose we place beneath or in connection with each washing bin or set
of washing bins or boxes such as are usually employed in wash houses connected
with dwelling houses, one or more tanks which will hold several times the contents
of such bin or bins ; and in a convenient part of such tank or tanks or in connection
therewith we fit a siphon communicating with the drain pipe. With this arrange-
ment the used water discharged from the washing bin or bius does not pass directly
into the drain pipe, but the successive portions are received into and accumulate in
the tank or tanks until there is sufficient to cover the top of the siphon. Every
time the tank or tanks become filled the water begins to pass off by the siphon, and
as the entering leg of the siphon dips down nearly to the bottom of the tank or
tanks, when once the water begins to pass off its discharge continues until the tank
or tanks become nearly emptied. In this way, instead of only comparatively small
quantities of water passing into the drain pipe without much flushing action, there
will be few discharges into the drain pipe, but each of such discharges will consist
of a large quantity of water and will have an efficient flushing action. Also besides
the mere flushing action, the large quantity of water thus passed at once into the
drain pipe will produce a sucking action which will tend to draw down fresh air
into the drain pipe and into the various branch waste pipes and soil pipes connected
with it, whilst preventing the passage of sewer gases into such waste pipes and soil
pipes.
The tanks may be made of any suitable material but we prefer to make them of
earthenware.
And in order that our said Invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing apparatus as constructed with our
improvements.
Figures, 1, and 2, on the accompanying sheet of drawings are vertical sections as
at right angles to each other of a wash house as provided with our drain flushing
apparatus. Figure, 3, is a horizontal section corresponding to figures, 1, and 2.
Figures, 4, is a plan of the pair of washing bins or boxes with which the wash house
is fitted, and figures, 5, and 6, are vertical sections as at right angles to each other
corresponding to figure, 4, these figures, 4, 5, and 6, being drawn to an enlarged
scale. In figures, 1, to 6, an ordinary simple siphon is shown, but in figures, 7, 8,
and 9, we show a compound siphon which we sometimes use, figure, 7, being
a horizontal section as at the line, A-A, in figures, 8, and 9, whilst figures, 8,
and 9, are vertical sections as at the lines, B-B, and C-C, respectively in figure, 7.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.

page_text: In the wash house shown in figures, 1, 2, and 3, there are two bins, 10, and under
each there is a tank or box, 11, of a size suitable for receiving several portions of
used water froin the bins, 10, the water passing from the bins down into the tanks
through short discharge pipes, 12, provided with the usual valves. The two
tanks, 11, are connected by a pipe, 13, so that one siphon, 14, 15, serves for leading
off the water from both tanks to the drain pipe, 16. The tanks, 11, are closed by
covers, 17, which are cemented so as to be watertight, and the top bend, 18, of the
siphon is placed just above the cover in order that when the tanks are full, all the
additional water required to start the running of the siphon will be only as much
as will about fill the top, 18, of the siphon, instead of having to fill the entire area
of the tanks to a depth equal to that of the siphon top, 18. As it is desirable that
as soon as the siphon commences to run the water from the tanks will pass off by
it as freely as possible, the ascending leg, 14, the top bend, 18, and the descending
leg, 15, are all made of the full bore of the drain pipe, 16; and whilst with such
proportions the water might overflow slowly without starting the siphonal action if
comparatively small quantities of water are added to the tanks, the probability of
such action taking place is considerably diminished by applying the close covers, 17,
to the tanks in the manner described.
The compound siphon shown in figures, 7, 8, and 9, is also designed to promote
the starting of the siphonal action on the addition of only a small quantity of water
to the tanks when they are full. This compound siphon is to some extent of
a common form, the ascending space being formed round the descending leg, 15, by
a larger pipe, 19, with a closed upper end. The upper part of the space is divided
by nearly radial partitions so as in effect to form four separate but combined
siphons; and the upper part of the descending leg, 15, is made conical and with
inlets, 20, 21, 22, for the several branches in different positions. The smallest
inlet, 20, at the top communicates with its ascending branch by a top bend, 23,
which is smaller and lower than the top parts of the other branches. The next
inlet, 21, communicates with a branch of about double the area of the smallest, and
the two remaining inlets, 22, which are lowest and equal and opposite to each other,
communicate with branches which are together of about double the area of the
second branch. When the tanks are full, only as much additional water will be
required for starting the siphon as will about fill the sinall top bend, 23, because as
soon as the water runs by the small inlet, 20, into the top of the descending leg, 15,
it will draw the air in succession out of the top parts of the other siphon branches
and cause them all to act siphonally and then the water flowing will quite fill the
bore of the drain pipe.
Pipes, 24, are provided for the escape of the air from the tanks, 11, when filling
and for its entrance when they are emptying, such pipes being by preference led to
the outside of the house as shown.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
Utilising the water used in wash houses, for flushing drains and thereby drawing
fresh air into waste and soil pipes connected to such drains, by means of tanks for
the reception of the used water and its accumulation to a certain extent such tanks
being provided with siphons arranged to empty them at once when full substantially
as hereinbefore described.
