IMPROVEMENTS IN OVERFLOWS of valve CLOSETS
Year: 1882

page_text: LETTERS PATENT to Henry Conolly of Hampstead Road in the County of
Middlesex and Adolphe Emil Hubert of Chelsea in the County of Middlesex
for an Invention of IMPROVEMENTS IN OVERFLOWS of valve CLOSETS.
PROVISIONAL SPECIFICATION left by the said Henry Conolly and Adolphe
Emil Hubert at tho Office of the Commissioners of Patents on the 30th June
1882.
HENRY CONOLLY of Hampstead Road in the county of Middlesex and ADOLPHE
EMIL HUBERT of Chelsea in the county of Middlesex.
IMPROVEMENTS IN
OVERFLOWS OF VALVE CLOSETS
The object of our invention is to provide an overflow to valve closets which shall
have the following advantages. It must always be sealed while there is any water
in the basin. It cannot be stopped up or choked, and the water therein is always
completely changed whenever the closet is used. It can also be made very cheaply.
To carry out this object we make, preferably in the same piece with the basin of
the closet, a pipe on the outside thereof, which communicates with, and opens into,
the interior of the basin near the bottom of the same. This pipe rises on. the
outside of the basin to the height we wish the water to stand inside the same;
and is then bent over and carried down to the discharge pipe of the closet. The
continuation of the overflow pipe between the bend thereof and the dis-charge pipe
may be made in a separate piece of lead or other material. Thus the water does
not overflow until it has reached the level of the bend, which ensures there always
being sufficient water in the basin to seal the overflow. The mouth of the overflow
pipe into the bottom of the basin may also be smaller than the pipe itself, and the
area of the bend may be made still larger. The overflow therefore cannot be
stopped up or choked; and if any material is washed into it, when the valve at
the bottom of the basin is opened, all such material is drawn down the pipe back
into the basin to be dis-charged through the valve.

IMPROVEMENTS IN
OVERFLOWS OF VALVE CLOSETS
The object of our invention is to provide an overflow to all kinds of valve closets
which shall have the following advantages. It must always be sealed and it
cannot be syphoned. It cannot be stopped up or choked and the water therein is
always changed whenever the closet is used.
In order to explain our invention and the method whereby we carry out the
aforesaid object we refer to the accompanying drawing.
Figure 1 is a vertical section of the basin of a valve closet fitted with one form of
our overflow. A is the basin of the closet. We make, preferably in the same piece
with this basin a pipe B on the outside thereof which pipe communicates with
and opens into the interior of the said basin at the bottom of the same through the
mouth.C which may either be entirely open as shewn in Figure 4 or may consist
of numerous perforations or preferably may consist of perforations combined with
a long slot at the bottom thereof as shown in Figure 5. This pipe B rises on the
outside of the basin to the height at which we wish the water to stand in the same
and is then bent over as at Ď and carried down to the discharge pipe E of the
closet. The continuation of this overflow pipe B between the bend D and the
discharge pipe E is preferably made as shown in the Drawing of a separate piece F
of lead or other material. Thus the water does not overflow from the basin of the
closet until it has reached the level of the bend D which ensures there being
always enough water in the said basin to seal the overflow pipe. The smallest
part of the said pipe B is the mouth O thereof and the sectional area of the said
pipe B increases gradually up to the bend D of the same. The overflow therefore
cannot be stopped up or choked and syphonic action is avoided while if any
material is washed up into the pipe all such material is drawn down the same back
into the basin when the valve at the bottom of the basin is opened and is discharged
through the said valve.
Figure 2 is a vertical section of the basin of a valve closet in which the overflow
pipe is not carried quite down to the bottom of the basin, as shewn in Figure 1.
In this case we prefer to form on the inside of the basin round the mouth of the
overflow pipe B, a cup or lip G to catch the water of the after flush and ensure
there being a seal on the overflow at all times. This cup or lip G may be formed
as shown in Figure 6 and is made in the same piece with the basin A. In this
manner the mouth C of the overflow pipe B with its cup or lip G can be placed at
any level in the basin that we may deem expedient.
In this case also the mouth
of the pipe is its smallest part, and the said pipe increases gradually up to the bend
thereof as hereinbefore explained to prevent any syphonic action and to secure the
overflow from being stopped up or choked.
Figure 3 is an elevation of a basin shewing another method of forming the bend
of the overflow hereinbefore described. In this method instead of making the bend
turn outwards from the basin as shewn in Figures 1 and 2 we bend the pipe over
on the outside of the basin and against or in juxtaposition to the same as shown.
This method takes up less space and renders it easier and cheaper to form the
basin and the overflow pipe and is suitable in some cases.
The action of this
overflow is the same as hereinbefore described,

page_text: Having thus particularly described and clearly explained our invention and the
manner in which the same is to be performed we claim as our invention which is
protected by the hereinbefore in part recited Letters Patent the improved overflows
of valve closets substantially as herein before described and declared and shewn in
the accompanying Drawing
In witness whereof I the said Henry Conolly on my own behalf and on
behalf of the said Adolphe Emil Hubert have hereunto set my hand and
seal this thirtieth day of December in the year of our Lord one thousand
eight hundred and eighty two.
HENRY CONOLLY. (LS)
