Improvements in and connected with Slop Water Closets.
We, JAMES DUCKETT AND SON LIMITED of Mitre Sanitary Works, Burnley,
in the County of Lancaster, JAMES DUCKETT of Woodleigh, Burnley aforesaid,
Sanitary Ware Manufacturer, and ARTHUR ASHWORTH 77, Albion Street,
Burnley aforesaid, Clerk, do hereby declare the nature of this invention to be as
follows:-
:-
The first part of our invention relates to slop water closets. Just under the seat,
we make the back of the earthenware pedestal (or pan) of "OG
shape in
horizontal section, instead of concave as heretofore. The convex part of the "OG"
is in the centre, and protrudes considerably, while the other portion of the pan in
the immediate proximity is concave. Excreta is much less likely to adhere to this
convex surface than to one that is either straight or concave. The depth of
this "OG" portion may be from nine to twelve inches, measuring downwards from
the underside of seat. From this part the remainder of the back of the "pan
recedes considerably, so as to be protected from fouling, even though the excreta
falls obliquely.
"
We also provide a ventilating appliance, the pipes and chanuels of which are
made of ample area, and so placed as also to convey the rain water from roof of
closet to the back of the pan to assist in cleansing it.
In carrying out this portion of our invention we fix an ordinary rain water pipe,
about three inches diameter more or less, to the back wall of the closet, preferably
to the outer face of wall. We fix a perforated cover at the head to keep out
leaves et cetera. One or two bends connect these pipes with a horizontal channel

channel is provided with a number of V or other suitably shaped openings, of such
size as to be together not less than the sectional area of the rain pipe, and placed
very near each other, so as to cause the water to flow in a broad stream, through
them and down the back of the pedestal or pan.
"
The seat has a hinged flap cover to render the ventilating appliances effective.
Another method of treating the pedestal or pan so as to prevent fouling
consists in fixing into a prepared recess, sheet glass or highly glazed porcelain in
place of the said "O G." This glass or porcelain in horizontal section may be
either straight curved or corrugated, and either vertical or sloping.
If excreta adheres at all to this exceptionally smooth surface, it can readily be
removed as it is very near the seat.

journals for supporting automatic tilting tanks, and consists in so constructing and
arranging them that they will not only answer their purpose as bearings, but will
also serve the additional purpose of buffers, the usual rubber buffers with their
auxiliary attachments being dispensed with altogether.
The steps or journals may be in the shape of a metal plate, bolted to the two
respective sides of the tipper box or receptacle. These have formed or cast on
their inner surfaces, a kind of recessed groove, pocket or socket, which serves the
double purpose of a journal or bearing for the axle of the tipper, and also as a
buffer or stop-piece to impede the motion of the tipper. This is effected in the
following novel manner :-
We construct the axle of the tipper as follows:-Upon a flat plate, which we
bolt to each outer side of tipper, we form a projection or stud, the lower end of
which rests upon the said step or journal.
The studs or axles are round on their under surface to fit into the recess or
socket of the steps above described, but they are formed on their upper surface
with a kind of lug or projection, which may perform the important function of
arresting the motion of the tipper, by falling into the recessed socket or groove,
but in other respects permit the tipper to work freely until so arrested.
projecting portion of the studs stands vertical when the tipper is in its normal
position, but when it tilts the studs turn with the tipper bringing the projection or
lug in an inclined position, when it comes flat against the side of recess in socket or
groove.

Instead of forming the bearing or socket with a recess as described, a suitable
stop-piece may be provided, against which the projection on the stud or plate comes
with the motion of the tipper in tilting.

Improvements in and connected with Slop Water Closets.
We JAMES DUCKETT AND SON LIMITED of Mitre Sanitary Works, Burnley,
in the County of Lancaster, JAMES DUCKETT of Woodleigh, Burnley aforesaid,
Sanitary Ware Manufacturer, and ARTHUR ASHWORTH, 77, Albion Street,
Burnley aforesaid, Clerk, do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The first part of our invention relates to slop water closets. Just under the seat
we make the back of the earthenware pedestal (or pan) of "OG" shape in
horizontal section, instead of concave as heretofore. The convex part of the "OG"
is in the centre, and protrudes considerably, while the other portion of the pan in
the immediate proximity is concave. The excreta is much less likely to adhere to
this convex surface than to one that is either straight or concave. The depth of
this "OG" portion may be from nine to twelve inches measuring downwards from
the underside of seat. From this part the remainder of the back of the pan
recedes considerably, so as to be protected from fouling, even though the excreta
falls obliquely.
We also provide a ventilating appliance, the pipes and channels of which are
made of ample area, and so placed as to convey the rain water from roof of closet
to the back of the pan to assist in cleansing it.
In carrying out this portion of our invention, we fix a surface or rain water pipe

page_text: about three inches diameter more or less, to the back wall of the closet, preferably
to the outer face of wall. We fix a perforated cover at the head to keep out
leaves et cetera. One or two bends connect this pipe with a horizontal channel

channel is provided with a number of V or other suitably shaped openings, of such
size as to be together not less than the sectional area of the rain pipe, and placed
very near each other, so as to cause the water to flow in a broad stream through
them, and down the back of the pedestal or pan.
The seat has a hinged flap cover to render the ventilating appliances effective.
Another method of treating the pedestal or pan so as to prevent fouling consists
in fixing into a prepared recess, sheet glass or highly glazed porcelain in place of
the said "OG." This glass or porcelain in horizontal section may be either
straight, curved, or corrugated, and either vertical or sloping.
If excreta adheres at all to this exceptionally smooth surface, it can readily be
removed as it is very near the seat.
The next portion of our invention relates to certain improvements in the steps
and axles for supporting automatic tilting tanks, and consists in so constructing and
arranging them that they will not only answer their purpose as bearings, but will
also serve the additional purpose of buffers the usual rubber buffers with their
auxiliary attachments being dispensed with altogether.
The steps and axles may be in the shape of metal plates bolted to the two respective
sides of the tipper and tipper box or receptacle. The steps have formed or cast
on their inner surfaces, a kind of recessed groove, pocket or socket which serves
the double purpose of a bearing for the axle of the tipper, and also as a buffer or
stop-piece to impede the motion of the tipper. This is effected in the following
novel manner :-
We construct the axle of the tipper as follows:-Upon a flat plate which we
bolt to each outer side of the tipper, we form a projection or stud the lower end of
which rests upon the said step.
The studs or axles are round on their under surface to fit into the recess or
socket of the steps above described, but they are formed on their upper surface
with a kind of lug or projection, which may perform the important function of
arresting the motion of the tipper, by falling into the recessed socket or groove,
but in other respects permit the tipper to work freely until so arrested. The
projecting portion of the studs stands vertically when the tipper is in its normal
position, but when it tilts, the studs turn with the tipper bringing the projection or
lug in an inclined position, when it comes flat against the side of the recess in
socket or groove.
Instead of forming the bearing or socket with a recess as described, a suitable
stop piece may be provided, against which the projection on the stud or plate
comes with the motion of the tipper in tilting.
In the accompanying drawings, Figs. 1 and 2 are elevation and plan respectively,
representing the first part of our invention, which consists in making the back of
the earthenware pedestal or pan of "OG" shape in horizontal section, instead of
concave as heretofore. As seen in Fig. 2, the convex portion A of the "OG" is
in the centre, and protrudes considerably as shewn, while the remaining portion of
the pan in the immediate proximity is concave. The object of constructing the
back of the pedestal in this manner is to prevent, as much as possible, excreta
adhering thereto. The pedestal extends in this shape to the depth of about nine to
twelve inches, when the remainder of the back of the pan or pedestal as shewn at B
recedes considerably, so as to be protected from fouling.
In Fig. 1 is also shewn a ventilating appliance of ample area to permit of free
ventilation of the closet pan, and at the same time so placed as to convey the rain
water from the roof of closet to the back of the pan to assist in cleansing it.
C is the ventilating pipe, which may be an ordinary rain water pipe three inches
or so in diameter fixed preferably to the outer face of the wall of the closet, and
covered at its head with a perforated cover to keep out the dirt. This pipe

page_text: communicates with a horizontal channel D formed at the back of the pedestal or
pan. The channel is provided with a number of V shaped openings E, as seen in
Fig. 6, which may be together of the same sectional area as the pipe, and are in
close proximity to each other, in order to distribute the water in a broad stream
down the back of the pedestal or pan. W is the seat and X the floor of closet.
In another arrangement to prevent fouling, as seen in Fig. 3, we fix in a prepared
recess at the back of the pan a sheet of glass F or a highly glazed piece of
porcelain or similar material. The said piece of glass or porcelain F, instead of
being straight as shewn, may be curved or corrugated, and either vertical or sloping.
Excreta, should it adhere at all to this exceptionally smooth surface, may be
readily removed therefrom, as it is very near the seat.
Figs. 4 and 5 represent the next part of our invention, which relate to the steps
and axles of automatic tilting tanks. Referring to Fig. 4, G is the tipper fitted
with our improved combined axle and buffer stop piece, which consists of a metal
plate H bolted to the tipper and cast with the axle J, formed with a lug or
projection K, which stands vertically when the tipper is in its normal position. In
Fig. 5 is represented the step or plate L which is fitted on to each side of the tipper
box (for convenience not shewn on the drawings) and formed or cast on its inner
surface is a kind of recessed groove, pocket, or socket M, which serves the double
purpose of a bearing for the axle of the tipper, and also as a buffer or stop piece to
impede the motion of the tipper. For greater clearness the axle J provided with
lug or projection K (when in its normal position) is shewn devoid of the plate H,
by which it is fixed to the side of the tipper. Plate H is however shewn in dotted
lines, illustrating how, when the tipper tilts, the lug or projection K falls into the
recess or pocket M, whereby it is arrested, and it is also checked in its return
movement by the straight side of the projection K coming against the vertical
face N of the grooved recess M.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved construction and arrangement of closet pedestal or pan
with "OG" section and with back portion thereof receding considerably as at B,
substantially as described and illustrated in Figs. 1 and 2 for the purpose set
forth.
2. The improved ventilating appliance as applied to waste water closets in
combination with √ shaped openings E, and means of collecting rain water from
roof of closet, and distributing the same in a stream down the back of pedestal or
pan substantially as described and illustrated in Figs. 1 and 2.
3. The application of sheet glass or highly glazed porcelain to the back of
closet pedestal or pan, substantially as described and illustrated in Fig. 3 for the
purpose described.
4. The improved construction of steps of tipper boxes and axles of tippers, in
combination with novel means for arresting the motion of the tipper in either
direction, substantially as described and illustrated in Figs. and 5.
5. The lug or projection K on axle J arranged to work in grooved recess M of
step L, substantially as specified for the purpose set forth.
