IMPROVEMENTS IN WATER CLOSETS
Year: 1884

page_text: We STEPHEN SMITH PHILLIPS and HENRY FREDERICK GREEN both of 10 Baker
Street, Portman Square in the county of Middlesex Sanitary Engineers do hereby
declare the nature of our said Invention for IMPROVEMENTS IN WATER CLOSETS to be
as follows:-'
Our invention relates to water closets and has for its object the construction of
the basin and the trap thereof in one piece and in such a manner as to combine
the advantages of what are known as the wash out system and the valve systemn
of construction while at the same time as we retain in the basin a comparatively
large amount of water when the valve is opened the discharge of all matter in the
basin is rendered extremely certain of accomplishment the more so as the bend of
the trap is comparatively at a low level. Our method of construction also provides
for the easy and efficient inspection of the pipe or drain or sewer into which
the trap leads and also of the valve and other parts of the basin or of the trap
thereof.
To carry out this object we construct our basin and the trap thereof in one piece
and preferably of glazed or other earthenware and the side of the basin towards nud
next to the trap is vertical or thereabouts while the opposite side is brought down
in an inclined direction thereto and the outlet from the basin is formed at the
bottom of the vertical side from which outlet rises the trap. The lower part of the
bend of this trap is a little above the level of the top of the outlet or thereabouts
and on this bend and round the walls of the trap is formed a suitable seating for a
valve preferably somewhat inclined downwards towards the end of the trap and
above this seating against the side of the basin is hinged a duly weighted valve
which will shut against the weight of the water on the seating and retain the water
in the basin. The trap beyond the valve is bent downwards and the end thereof
is duly fitted to be attached to the pipe or drain or sewer. A passage is made in
the vertical side of the basin which preferably opens into the trap just below the
valve and extends upwards to the level at which we desire the water to stand in
the basin where it opens into the upper part of the bend of the trap above and
outside the valve which upper part of the bend is extended upwards therefor and .

in the top of this upper part of the bend is formed a cap or inspection door which
can be removed for purposes of inspection of the trap or of the valve therein or of
the pipe or drain or sewer to which the trap is attached or connected.
Thus when the valve is closed the water fills the basin up to the level of the
top of the passage in the vertical side thereof when the overflow falls into the
trap above and outside the valve and when the valve is opened there is a clear
'course for the water contained in the basin to pass over the bend of the trap into
the pipe or drain or sewer as is the case in what are known as the wash out basins
and all matter contained in the basin is certainly and effectively removed.

page_text: We STEPHEN SMITH PHILLIPS and HENRY FREDERICK GREEN both of 10 Baker
Street Portman Square in the county of Middlesex Sanitary Engineers do hereby
declare the nature of our said invention for IMPROVEMENTS IN WATER CLOSETS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :--
C
Our invention relates to water closets and has for its object the construction of
the basin and the trap thereof in one piece and in such a manner as to combine
the advantages of what are known as the wash out system and the valve system
of construction while at the same time as we retain or can retain in the basin a
comparatively large amount of water when the valve is opened the discharge of all
matter in and from the basin is rendered extremely certain of accomplishment the
more so as the bend of the trap is at a comparatively low level. Our method of
construction also provides for the easy and efficient inspection of the pipe or drain
or sewer into which the trap leads and also of the valve and other parts of the
basin and of the trap thereof.
In order to explain our invention and in what manner the same is to be performed
we refer to the accompanying drawing in which we have shewn one and what we
consider to be a preferable form and style of this our improved water closet.
Figure 1 is a vertical section of the water closet. Figure 2 is an horizontal
section of the same taken at a. b. in Figure 1.
In this our improved water closet the basin A and the trap B thereof are made
in one piece and preferably of glazed or other earthenware and the side C of the
said basin A towards and next to the said trap B is preferably vertical or
thereabouts while the opposite side D is brought down in an inclined direction
thereto and the outlet E from the said basin A is formed at the bottom of the said
side C from which outlet E rises the said trap B. The lower part F of the bend of
this trap B is a little above the level of the top of the outlet E so that the lower
edge of the side C forms a dip by the which the said trap B is always seated and
on the said lower part F of the bend thereof and round the walls of the said trap B
is formed a suitable seating G for a valve which seating G is preferably somewhat
inclined downwards toward the end K of the said trap B as shown in the drawing
and above the said seating G and against the said side C of the basin A is hinged
a suitable valve H so duly weighted as to shut on the seating G against the weight
of the water and retain the said water in the said basin A. The trap B beyond
the valve His bent downwards and the end K thereof is fitted to be attached or
connected to the pipe or drain or sewer in any usual or convenient or suitable
manner as may be desirable in each case. A passage M is made in the side C of the
basin A which passage M opens at its lower end preferably by a curve as shewn in
the drawing into the trap B just below the valve H and the said passage M extends
upwards in the said side C to the level at which we desire the water to stand in
the said basin A where and at which level the said passage M opens into the upper
part N of the bend of the said trap B above and outside of the said valve H which

page_text: upper part N of the bend is enlarged and extended upwards therefor and in the
top of the said upper part N of the bend is formed an aperture which can be tightly
closed by the usual cap or door P and when required for purposes of the inspection
or cleaning of the said trap B. or of the said valve H therein or of the pipe or drain
or sewer to which the said trap B is attached or connected the said cap or door P
can be removed and thereby the aperture be opened and thus all the parts aforesaid
of the water closet are easily and efficiently exposed to treatment or otherwise as.
is desired.
Thus when the valve H is closed as shewn in the drawing the water fills the
basin A up to that level at which the passage M opens into the enlarged and
extended upper part N of the trap B and the overflow if any falls into the said
trap B above and outside the said valve H but when the said valve H is opened
there is a clear course for the water contained in the said basin A to pass over the
bend of the said trap B into the pipe or drain or sewer as is the case in what are
known as the wash out basins and all matter contained in the said basin A is
certainly and effectively removed while. at the same time as is aforesaid the said
trap B will always be seated by the water retained in the bottom of the said
basin A.
As is herein before stated we consider that the form and style of the water closet
as shewn in the drawing and also the various shapes and proportions and sizes
of the several parts thereof as so shewn are extremely suitable and convenient for
carrying out our objects as hereinbefore declared but at the same time we may vary
all or some of these details aforesaid without departing from this our invention as
may be necessary having regard to the particular requirements of each separate
case.
°
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
1. The improved water closet substantially as hereinbefore described and set forth
and shewn in the accompanying drawing.
2. In a water closet the combination of the basin the trap the valve and the
overflow passage substantially as and for the purposes herein before described and
declared.
