PROVISIONAL SPECIFICATION.
Improvements in Latrines or Multiple Closets.
We, HENRY STEPHENSON and FRED STEPHENSON, of Huncoat Fire Clay
Works, near Accrington, in the County of Lancaster, Sanitary Ware Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
This invention is designed to improve the arrangement of the connecting pipes
from pan to pan of latrines or multiple closets with the object of obtaining a better
flush of the respective closets, also for preventing soil sticking to the sides of the
pane or such pipes, and moreover to ascertain what particular closet has been
blocked up, should this be the case by any large article or solid matter becoming
lodged in the pans or pipes, which has hitherto been difficult to determine.
In carrying our invention into effect, we form the connecting pipes, which lend
from one pan of a closet to another, with two or more ridges or flanges, one at the
bottom, and the other at the top, on the interior surface of such pipes, and at such
distance from the socket or spigot ends thereof, as may be found desirable. These
flanges conform to a segment of the circle or ourvature of the pipes, so as to have
a twofold object, namely:-
Firstly, the bottom flange is intended to dam up the water in the closet basin or
pan (which may be formed flat as usual) to prevent the excreta becoming baked
thereon, and
Secondly, the top flange is designed in conjunction with the lower flange to
interrupt large articles from passing through the pipes from pan to pan.
The flanges are preferably made to slope or incline away from the closet pan in
their immediate proximity towards the trap, so as to facilitate the flush. The
pipes may be provided with a covered junction for ready access in caso of blockage
or obstruction. Instead of the segmental flange at the top and bottom as described,
one only may be used at the bottom, or in some instances, the flanges may be.
continued completely around the inner circumference of the pipes, so as to form a
complete circle or annular flango.
The inlet to each pan is slightly higher than the bottom of pan to get a better
fall in the range of closets, and the whole system of latrines and connecting pipes
we prefer to fall or alope gradually from the flushing end to the trap. In other
arrangements, the closets have been set level from end to end, but by our
arrangement, it will be seen that not only is the flush considerably increased in
force, but also that the closet pans and a portion of the connecting pipes have
ufficient water in them to prevent the excreta baking on them, and at the same
ime prevent large articles from passing from closet to closet.

We, HENRY STEPHENSON and FRED STEPHENSON, of Huncoat Fire Clay
Works, near Acorington, in the County of Lancaster, Sanitary Ware Manu-
facturers, do hereby declare the nature of this invention and in what mauuer the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention is designed to improve the arrangement of the connecting pipes
from pan to pan of latrines or multiple closets with the object of obtaining a better
flash of the respective closets, also for preventing soil sticking to the sides of the
pan or such pipes, and moreover to ascertain what particular closet has been
blocked up, should this be the case by any large article or solid matter becoming
lodged in the pan or pipes, which has hitherto been difficult to determine.
In carrying our invention into effect, we form the connecting pipes, which lead
from one pan of a closet to another with one two or more ridges or flanges, one at
the bottom, and another at the top, on the interior surface of such pipes and at such
distance from the socket or spigot end theroof as may be found desirablo. These
flanges conform to a segment of the circle or curvature of the pipes, so as to have a
twofold object, namely,
Firstly, the bottom ridge or flange is intended to dam up the water in the closet
basin or pan (which may be formed flat as usual) to prevent the excreta becoming
baked thereon, and
Secondly, the top ridge or flange is designed in conjunction with the lower ridge
or flange to interrupt large articles from passing through the pipes from pan to pan.
The ridges or flanges are preferably made to slope or incline away from the closet
pan in their immediate proximity towards the trap, so as to facilitate the flush.
The pipes may be provided with a covered junction for ready access in case of
blockage or obstruction.
Instead of the segmental ridges or flanges at the top and bottom as described,
one only may be used at the bottom, or in some instances, the ridge or flange may
be continued completely around the inner circumference of the pipes, so as to form
a complete circle or annular ridge or flange. The inlet to each pan is slightly
higher than the bottom of pan to get a better fall in the range of closet, and the
whole system of latrines and connecting pipes, we prefer to fall or slope gradually
from the flushing rim to the trap.
In other arrangements, the closets have been set level from ond to end, but by
our arrangement it will be seen that not only is the flush considerably increased in
force but also that the closet pans and a portion of the connecting pipes have
sufficient water in them to prevent the excreta baking on them, and at the same
time prevent large articles from passing from closet to closet.
In the accompanying drawings,
Fig. 1 represents an arrangement of two multiple closet or latrine basins and
pipe connections constructed in accordance with our invention.
A A are the two closet basins or pans connected together by connecting pipe B,
which is formed with two ridges or flanges C and D on its interior surface, and at
any desirable distanco from the socket or spigot end of such pipe, but preferably
the lower one is placed near the socket, and the other a short distance therefrom.
These ridges or flanges formed to a segment of the curvature of the pipes serve a
twofold purpose, as will be readily scen. Not only does the bottom flange D dam
up the water contained in the closet basin or pan as shewn, and thereby prevents
excreta becoming baked thereon but the top flange or ridge in conjunction with the

page_text: lower flange is so formed as to prevent large articles from passing through the
pipe or pipes from pan to pan. We profer the flanges or ridges to slope gradually
away from the pan A, so as to improve the flush. The covered junction E is
provided for ready access in case there be any blockage.
Similarly the outlet junction F leading into trap G is also provided with a lid
or cover H. The said junction is also formed with an inclined ridge or flange J to
dam up the water in pan A.
Fig. 2 is an end view of the connecting pipe B showing clearly the depth of the
ridges or flanges C and D.
Figs. 3 and 4 represent a similar system or range of closet basins and connections,
but with the latter provided with only a bottom ridge or flange L to serve the
same purpose as the ridge or flange D described above. It is also provided with a
covered junction W for access.
Figs. 5 and 6 are longitudinal section and end elevation respectively of a
connecting pipe M having a flange or ridge O formed completely around the inner
circumference of the pipe as shewn, iustond of only partially. In this arrangement
the pipe will answer its purpose if fit to the pan in any position.
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 construction of connecting pipes or junctions, consisting of
ridges or flauges as for example C and D formed on the inner circumference of
such pipes to not only dam up.the water contained in closet pan or basin A in
immediate proximity, but also to prevent large articles from passing through the
pipe or pipes, substantially as described and shewn in Figs. 1 and 2.
2. In combination with the said ridges or flanges, the means for gaining access
to them, consisting of covered junction E, substantially as described and
illustrated.
3. The improved construction of connecting pipe or pipes of latrines or multiple
closets consisting of a bottom flange L, substantially as described and illustrated
in Figs. 3 and 4 for the purpose set forth, and also covered junction Win
combination with the same.
4. The modification illustrated in Figs. 5 and 6 consisting of ridge or flango O
formed completely around the circumference of connecting pipe or pipes of latrines
or multiple closets, substantially as described and illustrated.
