Improvements in or connected with Waste Water and other Closets.
I, WILLIAM THOMAS ALLEN, of The Skelts, Great Barr, near the City of
Birmingham, Builder, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to waste water and other closets, and has for its
objects, to prevent the blocking of the outlet of the pan, or the entrance to the
trap, by accumulated soil, paper and other matter and also to reduce the structural
height of the water closet and this I accomplish by providing the inlet to the
trap with radiating and downwardly inclined blades or webs, converging towards
the axis of the said entrance to the trap but separated at their inward ends by
a space equal to, or less than, the bore of the trap.
Thus in carrying out one form of my invention I make the entrance to the trap
of a waste water closet of a pummel or hopper shape and socketted at the mouth
to receive the lower end of the pan or basin of the closet, which may have one,
two, three or more pipe inlets or arms of any approved construction, situated at
a considerable distance from the trap entrance, so that waste or other water for
flushing purposes shall pass through the said inlets and drop vertically onto the
soil and paper lying at the bottom of the closet. The said inlet arms preferably
lead from a series of gullies or drains, and by turning round the basin, the inlets
may be presented in any desired direction and any such inlets as may not be
required may be cut off by blocking them up.
The entrance to the trap or the exit of the basin is fitted or formed integrally
with preferably vertically disposed webs, blades or vanes sloping downwards
towards the entrance to the trap bore and the matter falling upon them is broken
up or disintegrated and then gravitates down the sloping sides of the hopper
shaped pan and into the entrance of the pan. On flushing water falling
upon this disintegrated matter, the same is easily flushed away, by the water
passing under such portions of it as remain on the sloping sides of the pan and
prevents the formation of a plug or other obstruction.
If necessary, the blades may be detachable or made in sections for convenience
in fitting and I propose that the taper of the pan or at the mouth of the trap
should run to a choke of about two and a half inches, whilst the general bore of
the trap may be four inches, but when the blades are formed adjacent to the outlet
to the pan, then the neck of the pan is choked or made of a smaller diameter than
the entrance to the trap.
I also propose that the entrance of the trap shall be so flared or taper sided as
to constitute, in itself, a basin or pan made integral with a trap and which has its
top edge formed with a flange to receive a top pipe provided with suitable waste
or other flushing water inlets, instead of the said inlets being formed through the
walls of a bottom pan.

I, WILLIAM THOMAS ALLEN, of The Skilts, Great Barr, near the City of
Birmingham, Builder, do hereby declare the nature of this invention and in
what manner the same is to-be performed, to be, particularly described and așcer-
tained in and by the following statement:―
This invention has reference to waste and other water closets, and has for its
objects to prevent the blocking of the outlet of the pan, or the entrance to the
trap, by accumulated soil, paper and other matter, and also to reduce the
structural height of the water closets, and this I accomplish by providing the
bottom of the pan, or the inlet to the trap with radiating and downwardly inclined
blades or webs, converging towards the axis of the sail entrance to the trap but
separated from one another at their inward ends by a suitable space and slightly
overhang the said trap entrance.
Figure of the accompanying drawings represents a topside plan of a waste-
water closet pan constructed or formed in accordance with my invention.
Figure 2 is a longitudinal vertical section of the same upon the dotted liner,
Figure 1.
Figure is an underside plan of the said pan, which is adjustably relatively
to its trap so as to admit of the water inlet being disposed in any convenient
position, according to the location of the drain pipe or other waste water supply.
Figure is a cross section of Figure 2, upon the dotted line, showing the
shape of the inlet to the trap.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
In carrying out this form of my invention, I make the pan a, or the part of
the waste water closet structure which forms the, entrance to the trap b, of a
funnel or hopper shape and socketted or annularly recessed at the mouth a', to
receive the lower end of the pipe sections or basin of the closet, which in this
case is provided with a single water shoot or inlet arm ², passing directly through
the walls of the hopper-shaped pan, although the same may have one, two, three
or more such inlets or arms of any approved construction. The said inlet arm
(or armis) preferably lead from a gulley, or drain pipe by which the closet is sup-
plied with waste water for flushing purposes. The walls of the pan, adjacent to
the entrance of the trap b, are fitted or formed integrally with a series of radially
arranged webs, blades or vanes d. sloping downwards towards the said trap
entrance, which thus partakes of the shape shown in Figures 3 and 4 and the
matter falling upon them is, to an extent, raised from the surface of the pan
and also broken up or disintegrated and then gravitates down the sloping sides
of the hopper-shaped pan and into the entrance of the trap. On flushing water
falling upon this disintegrated matter, the same is easily flushed away by the water
passing under or coming behind such portions of it as remain on the sloping sides
of the pan, instead of falling upon the top thereof as usual, by the water thus
acting upon accumulated matter from underneath it and prevents the formation
of a plug or other obstructions and the closet is efficiently flushed and cleansed.
If necessary, the blades may be detachable or made in sections for convenience
in fitting and I propose that the taper of the pan or the mouth of the trap shall
be slightly choked, or made of smaller diameter than the said mouth by the over-
hanging or inwardly extending lower ends of the blades, and further, the general
bore of the trap may be contracted at 73, which consequently forms an automatic
syphon in the case of heavy flushes of water during storms or the like. The

page_text: entrance of the trap may be so flared or taper-sided as to constitute, in itself, a
basin or pan made integral with a trap and which has its top edge formed with
a flange to receive a top pipe provided with suitable waste or other flushing water
inlets, instead of the said inlets being formed through the walls of a bottom pan.
In the form of closet bottom pan and separate trap shown in the drawings,
the trap is considerably curved, whilst the shallow pan nests or seats itself, as it
into the said curve, so that the height of the structure is much reduced and
only slight excavations below the surface of a yard or the like are required for
the setting of the same. Further this construction of waste-water flushed closet
is particularly applicable for use in connection with shallow drainage systems, as
a twelve inch fall in the drainage pipe leading from the galley trap to the waste
inlet arm is sufficient to provide for the efficient flushing of the same. This also
admits of the gulley trap being placed close to the closet.
were,
Instead of providing the bottom of the closet with radiating blades extending
some distance up the walls thereof, I may obtain a like or nearly like result by
making the mouth of the trap of an undulatory or corrugated figure or with
inwardly directed and separated points.
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:
First In waste-water and other closets, providing the bottom of the pan, or
the walls of the closet adjacent to the entrance or inlet to the trap, with radiating
and downwardly inclined blades, webs or their equivalent, converging towards
the said inlet or entrance, substantially as and for the purpose described and set
forth.
Secondly-In waste-water and other closets, making the entrance to the trap
of a corrugated or undulatory figure and contracted relative to the bore of the
trap by overhanging and separated points, substantially as and for the purpose
as described and set forth.
Thirdly waste water or other closet, consisting of a funnel or hopper-
shaped pan, fitted to or formed integral with a trap and provided with one or
more water inlet arms, and with the walls of the same, adjacent to the entrance
to the said trap provided with a series of radiating and downwardly inclined
blades or webs converging towards the said trap entrance, substantially as
described and represented in Figures 1 to 4.
Dated this 2nd day of March 1899.
