page_text: Improvements in, or Additions to, Water Closets.
1, WILLIAM THOMAS ALLEN, of "The Skelts," Great Barr, near the City of
Birmingham, Sanitary Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to water closets, and has for its object, to provide means
for effecting a more efficient flushing of the interior walls of the pan and throat
and exit of the conical bottom.
In carrying out my invention, the improved closet consists of a coned or other
pan, with the lower or throat end fitting socket-wise within the mouth of a D or
other trap, whilst the upper end is fitted socketwise with a cylinder or pipe having
the usual seat at the top, the junction of the said pipe and pan preferably coming
below the ground level.
Directed into the middle of one side of the coned pan is the contracted outlet
or pipe leading from a gulley, chamber or passage, containing within it, a revolv-
ing flusher, also coming below the ground level, whilst facing the outlet of the
flushing chamber is a water-splitter consisting of a wedge shaped protruberance
or projection, coming forwards into the pan and adapted to divide the stream of
water issuing from the chamber and direct a greater part of the same upwards and
around the walls of the pan and pipe and efficiently flush the same.
Thus assuming that the gulley or chamber containing the flushing revolver is
below the ground level, and that surface drainage is caught within it, and that
when full the centre of gravity is brought forward from the centre of rotation,
then it revolves and empties the water precipitously into the chamber, when it
rushes down the inclined pipe into the pan striking the offside splitter in its path,
and then rebounds and is in part or wholly projected upwards and the upper part
of the pan and the lower part of the closet efficiently flushed. The lower part of
the pan below the split, may also at the same time be flushed, independently of
the head of water which falls after rebounding.
The splitter preferably consists of a projecting wedge-shaped horizontal lug
made integral with the pan, but the same may if necessary be in the form of an
attachment and I wish it to be understood that I do not limit myself to the shape
of the splitter or rebounder, so long as the same causes the water directed within
its path to run up the interior of the walls of the pan or closet and effectually
cleanse them.

page_text: I, WILLIAM THOMAS ALLEN, of "The Skelts," Great Barr, near the City of
Birmingham, Sanitary Engineer, 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:-
This invention relates to water closets, particularly to closets in which there is
little or no fall for the flushing water and has for its object, to provide means for
effecting a more efficient flushing of the interior walls of the pan and throat and
exit of the conical bottom.
Figure 1 of the accompanying drawings represents a section of a water closet,
adapted to be flushed by water derived from surface drainage, slops and other
waste, and embodying my improvements.
Figure 2 represents, upon an enlarged scale, a side elevation of the conical pan
or bottom part of the closet basin.
Figure 3 is a front elevation of the said pan and
Figure 4 is a vertical section of the same upon the dotted line a, Figure 3.
Figure 5 is a topside plan of the bottom pan.
Figure 6 is a cross section upon the dotted line a¹ Figure 5,
And Figure 7 is a cross section of Figure 3 upon the dotted line ².
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
According to my invention, the improved closet consists of a coned or other
bottom pan b, whose lower or throat end 61, fits socket-wise within the mouth c¹,
of a P or other trap c, whilst the upper end 62, is fitted socketwise with a cylinder,
basin or pipe a, having the usual seat, at the top, the junction of the said pipe and
pan preferably coming below the ground level as indicated in Figure 1.
Directed into the middle of one side of the coned pan at 63, is a contracted outlet
or pipe a¹, leading from a gulley, chamber or passage d, containing within it a
revolving flusher, ³, also coming below the ground level, and into which waste
or other water from drains, sinks and the like falls either from a pipe such as d,
or directly through a drain whilst facing the outlet of the flushing chamber and
coming on the opposite wall of the pan is a water-splitter or distributor consisting
of a wedge-shaped or wedge-sectioned protuberance or projection e, coming for-
wards into the pan and adapted to divide or split the impinging stream of water
issuing from the flusher chamber, and to direct a greater part of the same up-
wards and around the walls of the pan and pipe and thereby efficiently flush and
cleanse the walls of the closet, as well as getting rid of the excreta or other matter
in the pan.
Thus, assuming that the flushing revolver or tipper located in the chamber below
the ground level has been filled by surface drainage or by waste or town water
caught within it, and that when full the centre of gravity has been brought for-
ward from the centre of rotation, then the tipping vessel revolves and empties the
water contained within it precipitously into the chamber, from whence it rushes
into the pan, strikes the splitter lying within its path, and then rebounds and is
in part or wholly projected upwards, whereby the upper part of the closet and the
lower pan of the closet are efficiently flushed. The lower part of the pan below
the splitter, may also at the same time be flushed, independently by the head of
water which falls back into the said pan after rebounding.
The splitter preferably consists of a projecting wedge-shaped vertical lug made
integral with the pan, but the same may, if necessary, be in the form of an attach-

page_text: ment, and I wish it to be understood that the before described splitter may be
applied to different forms of closets than the particular form represented and alsc
to closets in which the pan and pipe or basin of the closet are combined or in one
element and either part and parcel or not of the trap.
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:-
In water closets, providing the walls of the pan, opposite to the flushing-water
inlet, with a water-splitter or distributor consisting of a wedge-section lug or web,
taper rib or equivalent protuberance, against which the stream of flushing water
impinges or strikes and is thereby divided and partly projected upwards, sub-
stantially as and for the purpose as described and set forth.
