Appliances for Flushing the Basins of Water Closets with Refuse
Liquids.
1, WILLIAM RAMSBOTTOM of Oak Hill Cottage, Manchester, Road, Accrington, in
the County of Lancaster, Builder, do hereby declare the nature of this invention
to be as follows:-
It is mainly intended to meet, in a convenient way, some of the conditions imposed
by local Authorities in relation to the disposal of waste waters which have been used
for domestic purposes; and to minimise the amount of attention requisite to the
efficient flushing of closets by means of such waste waters.
For the first reception of the refuse liquids I propose to use a cistern of suitable
capacity say from 5 gallons upwards which may be placed in any convenient
situation but which would usually be found outside the dwelling-house or premises
where the liquids are produced, and beneath the point at which they are discharged
from the premises. The cistern is to be fitted with a siphon, which I prefer should
be of the double cylinder or annular kind, with its inner tube or long limb projecting
through the bottom of the cistern, and dipping into a vessel so contrived as to
retain, after every discharge of the cistern, sufficient fluid to trap and "seal" the
siphon, and thereby to maintain an automatic, intermittent action in the arrangement.
The contents of the cistern are, at each voidance, to be led to the closet-basin or trunk
which is to be flushed.

Appliances for Flushing the Basins of Water-closets with Refuse
Liquids.
I, WILLIAM RAMSBOTTOM, of Oak Hill Cottage, Manchester Road in the Borough
of Accrington and County of Lancaster, Builder, 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 as set forth in my provisional specification, is mainly intended for
the effective and convenient flushing of water closets with waste waters which have
already been used for domestic purposes. The means I employ are fully described
herein, and are illustrated by the accompanying sheet of drawings, where, in the
several views, corresponding parts are indicated by similar letters of reference.
Figure 1 is a sectional elevation. Fig. 2 is a plan of the same in section on A. B.
Fig. 3 is an elevation in section, Figs. 4 and 5 are sectional elevations of similar parts
in planes at right angles to each other.
For the first reception of the refuse liquids 1 use a cistern (a) which may be placed
in any convenient position but which would usually be found outside the dwelling house
or premises where the liquids are produced, and beneath the point at which they are
discharged from the premises. The cistern may be made of fire-clay, which I find to
be suitable for the purpose, but other materials may be used. Its form and dimensions
too may be varied to meet special conditions. It is provided with an outlet siphon,
which I prefer should be of the double cylinder or annular kind with an inner tube (b)
and an outer covering-cylinder (c) having its upper end closed. The outer cylinder
may either rest solidly on the bottom of the cistern as shewn in Fig. 3,-suitable
openings being provided at its base for the free entrance of the liquids to be discharged

page_text: through it or, as I find to be advantageous and conducive to prompt action, it may
be supported clear of the bottom of the cistern, and may be allowed to swing freely
about a cross-bar or the edge of a web (d) resting on the inner tube as shewn in
Fig. 1.
The inner tube or long limb of the siphon projects through the bottom of the
cistern and dips into a lower vessel (e) so contrived as to retain after every discharge,
sufficient liquid to trap and seal the siphon.
It is essential to the satisfactory working of my combination that the emptying
of the cistern should occur only at intervals when it holds a quantity of liquid sufficient
to give an effective flush; and, in order that a siphon of the kind herein described
may have an action regularly intermittent it has been found necessary that air should
have access to its interior until the contents of the cistern have reached the proper
level, when the air-inlet must be closed. This I provide for in two ways. One method
is shewn in Fig. 1, where (f) is the entrance to an air passage terminating in a hole
at its upper end sufficiently small to be closed by the liquid itself when it begins
to flow over the edge of the long limb of the siphon. In the alternative method,
shewn in Figs. 4 and 5, air is admitted by a tube (9), passing through the covering
cylinder, and having a small hole at its lower end. The tube nearly reaches the angle
of a lipped notch (h) formed at the upper end of the long limb (b). In both cases it
is to be assumed, that when the siphon begins to operate, a current of liquid is passing
more than sufficient to seal the small air holes.
At each discharge, the contents of the cistern are led by ordinary means to the
vessel of the closet which is to be flushed.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The appliance of a cistern having an outlet siphon acting intermittently, sub-
stantially as described herein, for flushing the basins of water closets with refuse
liquids.
2. The methods of influencing the action of the siphon by the admission of air in the
two ways substantially as described.
3. The use of a cross bar or web (d) or their equivalent, for suspending the outer
cylinder, substantially as described.
