Improved Odourless Closets.
We, JOHN FRANCIS LIERNUR and WILLIAM PETER LIERNUR, both of
Monument Chambers, London, E.C., Sanitary Engineers, do heroby declare the
nature of this invention to be as follows:-
This invention relates to improvements in closets or receptacles for fecal matter,
and has for its object the provision of a closet or receptacle. of such a forin and
shape, as shall do away with the necessity of flushing with water, and at the same
time provide an apparatus that shall be free from smell, or like objections common
to the ordinary closet pan.
In order to carry out this invention we provide a pan or receptaclo of a
particular shape, made of any suitable material, but preferably of cast iron. This
Baid pan is of the ordinary round or oval shape and size at the top, with a slight
taper for a short distance downward. At the base of this taper the pan is
enlarged, so as to form a short flange at an angle of 45° or thereabouts, from the
bottom of which the walls of the pan are continued downward in a tapering form
till the pan terminates in a pipe of the same diameter as, or near to, that of the
soil pipe.
A second receptacle is provided, to receive the upper pan or receptacle, which
consists of a closed shaped vessel of similar material to the upper pan,
terminating at one end with a downward pipe, branching into or forming part of
the soil pipe, and at the other end having a short length of pipe dipping into the
dished part of the receptacle from the upper surface into which the bottom part
or pipe of the upper pan or receptacle aforesaid is fixed. This lower or second
receptacle is made narrow, being only equal in width to the diameter of the pipes
belonging to it.
It is provided with a moveable lid or cap in the upper surface for the purpose of
getting at and removing any accidental obstruction should it be required, and also
with a small branch pipe at the opposite end to the soil pipo and adjacent to the
inlet branch, which may be connected with the waste pipe from the house sinks or
any other waste water pipe, should it be so desired, so that the waste water in
passing through to the soil pipe, may be utilised for flushing purposes.
The principle on which this invention has been devised is as follows:-The
effluvia arising from the fecal matter being denser than the atmosphere does not
rise beyond a certain approximate height above the surface thereof, and the lower
part of the pan is made of sufficient length to secure its being always below the
enlarged flanged portion of the sides hereinbefore described.
The pan is made of euch a shape that the excrement falls direct into the dished'
part of the bottom receptacle. The junction of the shaped vessel with the
vertical soil pipe branch forms a syphon, the overflow of which is above the
bottom of the inlet branch. It is well known that fecal matter is of the greater
part, of a liquid or semi liquid nature, and the bottom receptacle being no wider
than the inlet pipe, it readily flows away over the syphon into the soil pipe, and
the small quantity, which remaining forms.a seal provonts the escape of any foul
gases from the soil pipe.

page_text: We, JOHN FRANOIS LIERNUR and WILLIAM PETER LIERNUR both of
Monument Chambers, London, E.C., Sanitary Engineers, do hereby declaro 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 improvements in closets or receptacles for fecal inatter,
and has for its object the provision of a closet or receptacle, of such a form and
shape as shall do away with the necessity of flushing with water, and at the same time
provide an apparatus that shall be free from smell, or like objections cominon to
the ordinary closet pan.
In order to carry out this invention we provide a pan or receptacle of a
particular shape, made of any suitable material, but preferably of cast iron. This
said pan is of the ordinary round or oval shape and size at the top, with a slight
tapor for a short distance downward. At the base of this taper the pan is
enlarged, so as to form a short flange at an angle of 45° or thereabouts, from the
bottom of which the walls of the pau are continued downward in a tapering form
till the pan terminates in a pipe of the same diameter as, or near to, that of the
soil pipe.
A second receptacle is provided, to receive the upper pan or receptacle, which
consists of a closed shaped vessel of similar material to the upper pan,
terminating at one end with a downward pipe, branching into or forming part of
the soil pipe, and at the other end having a short length of pipe dipping into the
dished part of the receptacle from the upper surface into which the bottom part or
pipe of the upper pan or receptacle aforesaid is fixed. This lower or second
receptacle is made narrow, being ouly equal in width to the diameter of the pipes
belonging to it.
It is provided with a moveable lid or cap on the upper surface for the purpose
of getting at and removing any accidental obstruction should it be required, and
also with a small branch pipe at the opposite end to the soil pipe and adjacent to
the inlet branch, which may be connected with the waste pipe from the house sinks
or any other waste water pipe, should it be so desired, so that the waste water in
passing through to the soil pipe, may be utilised for Hushing purposes.
The principle on which this invention has been devised is as follows:-The
effluvia arising from the fecal matter being deuser than the atmosphore does not
rise beyond a certain approximate hoight above the surface thereof, and the lower
part of the pan is made of sufficient length to secure its being always below the
enlarged flanged portion of the sides hereinbefore described.
The pan is mude of such a shape that the excrement falls direct into the dished
part of the bottom receptacle. The junction of the shaped vossel with the
vertical soil pipe branch forms a syphon, the overflow of which is above the bottom
of the inlet branch. It is well known that fecal matter is of the greater part of a
liquid or semi liquid nature, and the bottom receptacle being no wider than the
inlet pipe, it readily flows away over the syphon into the soil pipe, and the same
quantity, which remaining forms a seal, prevents the escape of any foul gases from
the soil pipe.
In order that our invention may be readily understood, reference is made to the.
accompanying drawings in which
Fig. 1 represents a longitudinal scation of the improved closet pan or receptacle,
Fig. 2 being a plan, and Fig. 3 an end view of the same partly in section. Figs. 4
and 5 are sectional plans of the bottom portion of said pan.
In these views A is the upper part of the pan, having at a convenient position in

page_text: its length an enlarged portion A', forming a short flange at an angle of 45° or
thereabouts. From the bottom of this enlarged portion the walls of the pan are
continued downward in a tapering form in the manner shown in the drawing, till
this said upper part of the closet pan terminates in the pipe E.
The lower part of the closet pan is of the sectional shape shown in Fig. 1,
having a narrow width and flat sides B. One end of this lower pan terminates in
a short downward pipe C, provided with a socket S and spigot S', for connecting
to the soil pipe. The other end is provided with a short socket pipe D, the lower
end of which is made long enough to reach below the syphon overflow neck of the
pan at G. This short socket pipe receives the lower end E of the upper pan A,
and when fixed is made a perfectly air tight joint. T is a small branch pipe for
connecting the waste pipe from the house sinks, or any other waste pipe, and which
may or may not be used for flushing purposes as may be convenient.
is a moveable lid or cap at the top of the lower pan, for the purpose of getting
at and removing any accidental obstruction in the closet pan.
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. In closets or receptacles for fecal matter, the provision of an upper and lower
pan or receptacle each of a special shape, said upper pan having an enlarged
angular or conical portion at a convenient part of its walls, and terminating in its
lower part in a pipe, and said lower pan being provided with a short branch to
form a termination of the lower portion of the upper pan, a vertical portion for
connecting the pan to the soil pipe of the house or premises, a small pipe for
connecting to a waste water pipe, and covers for the said pan, substantially as and
for the purpose herein set forth aud described and illustrated by the accompanying
drawings.
