Improvements in connection with the Flushing of Drains, Sewers,
Water Closets, and the like.
I, 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:-.
My invention relates to means to be employed in connection with the flushing of
water courses, such as surface drains, sewers, the pipes of water closets and latrines
and the like, and consists, in the one part, in combining with a drainage suff or gully
trap, a revolving tipper or tumbler, that is, a rotating or part rotating
catch vessel located within the interior of the gully or catch pit of the
suff and under the grating, so that all waste and drained waters which
normally fall
the main drain,
intercepted and after having
accumulated into a considerable volume, are then automatically and suddenly
liberated owing to the centre of gravity of the liquid caught in the tipper and
withheld from the drain falling without the centre upon which the said tipper or
revolver is mounted ; and in another part, in means for separating or dividing a
given volume of flushing water with two, three or more quantities for the flushing of
a corresponding number of drains, gullies, latrines, closets or the like.
into
are
Thus according to the first part of my invention, I let a gully trap into the ground,
which trap is in communication with a drain having a suitable fall, and has an interior
of sufficient capacity to have mounted within it, an open-topped vessel with its.
mountings disposed a little out of the centre of gravity and with the open top coming
within a suitable distance of the grating of the drain of a yard or other surface and at
a suitable distance from the seal or bend of a trap. The shallow gully or chamber is
combined with an outlet or pipe and the whole is preferably of the figure of a P trap
but to this I do not limit myself, as the dip or seal, with the outlet, may be made
separate from the body or chamber wherein the catch flusher is mounted.
The neck of the P-outlet is socketted into a drain which may fall towards the catch
pit of a water closet or to the pipe of a latrine or to the P trap in connection with a
closet or latrine, from which water flows to the main culvert or sewer.
The closets or latrines may be in series or ranges, or they may be flushed
independently, or each closet may have a separate gully trap and flusher.
By this aforesaid part of my improvements, all sanitary requirements as to the
proper flushing of closets and drains are fulfilled or carried out by the use of water
from surface drainage without any additional cost for water supply and a powerful
flush of water is discharged in a single volume at a very shallow depth, as the drains
need only be removed but a very short distance from the surface and shallow water.
closets can be employed.
If necessary, the gratings of the gullys may have leads for conducting the water to
the tipper, or the tipper chambers may be a distance from the gratings or the
revolvers or tippers may be fitted within supplementary chambers below the gully
chambers.
In carrying out one form of the second part of my invention, in connection with
the Bushing of a pair of branch pipes or latrines or the like, I provide the bottom of a

page_text: gully or the chamber wherein the revolver works (which chamber may be built
up in any convenient way) with a conoidal or wedge-shaped swell, projection or
rise, with the apex coming central, so that when the revolver or tipper is
rotated, the falling volume of water is split or divided into two portions, which
respectively fall into and pass down the two passages or channels, each of which
is preferably made in the form of a P bend or P trap. This splitting of the
volume of water thrown over by the revolver is a great advantage in flushing
two or more drains at one time by one flush of water, which may be either
collected from surface drainage or supplied from a dripping tap or other source.
The bottom of the gully or other chamber wherein the revolver is located may
be made in segments or built up from brickwork and may be separate
from the top pipe, and the top pipe or shell may fit socket-wise into the walls
surrounding the base of the water-splitter or divider.
When four channels are to be flushed at one operation then the lower part or
bottom of the chamber, which forms the commencement of the channels, is formed
into the figure of a four-sided pyramid, with the apex coming at the top and
with the sloping sides falling away to the respective entrances to the said
channels, which may lead to gullies, traps, closets or the like requiring to be
flushed.
I wish it to be understood that I do not confine myself to the exact figure of
the dividing means herein described, as two, three or more holes, entrances or
pipes leading to flushing channels, or like expedients, may be employed with the
same effect.
As another form of this part of my improvements, I provide the bottom of the
chamber wherein the revolver or tipping vessel is located, with a shunt which is
alternatively moved from one to another of a series of channels by the action of the
falling water. Thus the bottom of the chamber may have fitted within it, a hanging
or jointed plate with foot-boards upon the opposite sides leading respectively to
channels to be flushed, so that in the case of a double channel, the flush, on dropping
upon one side falls upon the foot board or inclined side and presses it back to the
other side, so that the next tip is passed down the other side which is open, and so on
alternatively flushing first one and then the other of the passages.
Instead of employing a shunt which swing with top and bottom parts above and
below the joint, which come alternatively against stops, I may employ a rotary shunt,
mounted either horizontally or vertically, and having part helices or vanes arranged
so that the falling water shall cause passages within it to be intermittently and
consecutively in front of a series of different channels leading to different closets or
the like which are thus flushed in turn.
Improvements in connection with the Flushing of Drains, Sewers,
Water Closets, and the like.
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 :-
My invention relates to means to be employed in connection with the flushing of

page_text: water courses such as surface drains, sewers, the pipes of water closets and latrines
and the like, and consists in the one part in combining with a drainage suff or
gulley trap, a revolving tipper or tumbler, that is, a rotating or part rotating catch-
vessel located within the interior of the gulley or catch pit of the suff and under the
grating so that all waste and drained waters which normally fall into the main drain,
are intercepted and after having accumulated into a considerable volume, are then
automatically and suddenly discharged or liberated owing to the centre of gravity
of the liquid caught and accumulated in the tipper and withheld from the drain
falling without the centre upon which the said tipper or revolver is mounted; and in
another part, in means for separating or dividing a given volume of flushing water
into two, three or more quantities for the flushing of a corresponding number of
drains, gullies latrines, closets or the like.
Figure 1 of the accompanying drawings represents a gulley trap provided with
means for flushing a water closet or the like, and constructed and arranged according
to this part of my invention.
Thus, the gulley trap or catch pit a, which is let into the ground, is in communi-
cation with the drain having a suitable fall, and has an interior of sufficient capacity
to have mounted within it, an open top vessel b, with its pivot mountings b¹, which
rest in bearings a², in the sides of the trap, disposed a little out of the centre of
gravity and with the open top 62 coming within a suitable distance of the hinged or
other grating or grid c, of the drain of a yard or other surface and at a suitable
distance from the seal or bend of a trap. The gulley or chamber is combined with
an outlet or pipe, a' leading to the drain, and the whole is preferably of the figure of
a P trap but to this I do not limit myself, as the dip or seal, with the outlet, may be
made separate from the body or chamber wherein the catch flusher is mounted.
The neck of the P-outlet is socketted into a drain which may fall towards the
catch pit of a water closet or to the pipe of a latrine or to the P trap in connection
with a closet or latrine, from which water flows to the main culvert or sewer.
The closets or latrines may be in series or ranges, or they may be flushed
independently, or each closet may have a separate gulley trap and flusher.
By this aforesaid part of my improvements, all sanitary requirements as to the
proper flushing of closets and drains are fulfilled or carried out by the use of water
from surface drainage without any additional cost for water supply and a powerful
flush of water is discharged in a single volume at a very shallow depth, as the drains
need only be removed but a very short distance from the surface and shallow water
closets can be employed.
If necessary, the gratings of the gulleys may have leads for conducting the water
to the tipper, or the tipper chambers may be a distance from the gratings or the
revolvers or tippers may be fitted within supplementary chambers below the gulley
chambers.
Figure 2 represents in vertical section, another form of automatic waste-water
flushing gulley trap, provided with a revolving tipper and also with means for split-
ting or dividing the volume of flushing water discharged from the flusher into two
parts for flushing two separate closets or drains, as according to one form of the second
part of my invention.
Figure 3 is vertical section of Figure 2 upon the dotted line x, and
Figure 4 is a horizontal section of the trap upon the dotted line A, Figure 3, show-
ing in plan the formation of the bottom of the trap for dividing the volume of flushing
water into two bodies.
The same letters of reference indicate corresponding parts in Figures 2, 3,
and 4.
In carrying out this form of the second part of my invention, as represented in
the said Figures 2, 3 and 4, in connection with the flushing of a pair of branch pipes,
water closets, latrines or the like, I provide the bottom a², of a gulley or the
chamber a, wherein the revolver b, works (which chamber may be built up in any
convenient way) with a conoidal or wedge-shaped swell, projection or rise a', with
the apex as coming central, so that when the revolver or tipper is rotated, the

page_text: discharged volume of water falls upon the said wedge-shaped rise and is thereby split
or divided into two portions, which respectively fall into and pass down the two
passages or channels a¹, a¹, each of which may be made in the form of a P bend or
P trap. This splitting of the volume of water thrown over by the revolver is a great
advantage in flushing two or more drains at one time by one flush of water, which
may be either collected from surface drainage or supplied from a dripping tap or
other source.
The bottom of the gulley or other chamber wherein the revolver is located may
be made in segments or built up from brickwork and may be separate from the top
pipe, and the top-pipe or shell may fit socket-wise into the walls surrounding the base
of the water splitter or divider.
Figure 5 represents a vertical section of another form of this part of my invention,
adapted to divide a falling volume of water into four practically equal parts for
simultaneously Alushing four independent or separate drains, branch pipes or closets.
Figure 6 represents a horizontal section of Figure upon the dotted line B,
showing the formation of the bottom of the gulley.
Thus the bottom 2, of the trap a, which forms the commencement of the four
channels or passages a³, a, a, a, to be simultaneously flushed, is formed into the
figure of a four sided pyramid b, with the apex b', coming at the top and with the
eloping sides 68, 64, 65, 6, falling away respectively to the separated entrances of
the said channels, which may lead to traps, closets, or the like requiring to be
flushed: 6 is the revolving flusher.
I wish it to be understood that I do not confine myself to the exact position and
figure of the dividing means herein described, as where the body of flushing water
does not drop upon the splitter vertically but passes more or less down a horizontal
channel, then it may be made to impinge upon a wedge-shaped extension
extensions interposed between two or more drains or other passages.
or
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: The combination with a drainage suff or gulley trap, of a revolving flusher
or tipper, that is, a rotating or part-rotating catcli-vessel located within the interior
of the gulley or catch pit of the suff and under the grating thereof, so that all waste
and drain water which would otherwise fall into the main drain, are intercepted by
the catch vessel, and after accumulating to a considerable volume, are then auto-
matically and suddenly discharged into the drain, passage or the like to be flushed,
substantialy as described and set forth.
Secondly Dividing a volume of flushing water into two or more parts for
simultaneously flushing two or more drains, passages, or the like by means of a
"splitter", consisting of a wedge-shaped, conical, pyramidal or like projection or
extension or projections, fitted, located or coming within the path of the said volume
of water substantially as described and set forth.
Thirdly Providing at the bottom of a gulley trap, drainage, suff or like chamber,
a divider or splitter, consisting of a wedge or pyramidal shaped formation with the
apex presented uppermost, so as to divide or split a falling volume of water into two
or more parts for flushing a corresponding number of drains, passages and the like,
substantially as described and set forth.
