COMPLETE SPECIFICATION.
Improvements in Latrines.
I, MOSES JAMES ADAMS, Engineer, Park Lane, Sanitary Works, Leeds, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
My improvement consists in the special form of closet pan and its arrangement
to form a multiple closet, though the same is sometimes used singly whereas
multiple closets have been formed by using what is known as a hopper basin
placed on a junction of a longitudinal drain pipe with or without a trap immedi-
ately under the pan. Such a closet pan as I now shew has never been so used and
in the combination of the pan herein fully described with a longitudinal drain
pipe.
Without any trap intervening I am introducing an apparatus which is novel
and the special features of which render it of considerable utility. In earlier
applications I have shewn a hopper closet with wings or otherwise so formed that
the space between the closet and wall now usually left open is closed in so that
there is no space wherein dust and other undesirable matter may accumulate but
not such a combination as that now described. It will be seen on reference to the
are shewn in some cases. I
accompanying drawing that three closet pans A A
use a contracted neck as dotted line G of less diameter than the vertical opening
to drain, these closets are connected to drain pipes C C C by sockets B B B and it
will be apparent that the drain C may be laid deeper in the ground by adding a
piece of vertical pipe between the spigot of the closet and the sockets B B B. Con-
nected to the drain pipe I shew a syphon 1), this syphon draws up a certain amount
of liquid in the closets and is so constructed that its syphonic action periodically
withdraws the contents of the drain and closets discharging into it to any drain or
receiver as shewn by arrow. Instead of 1) I may use a weir or other equivalent or
I may dispense with these. I have shewn at È E Ea flushing pipe which fre-
quently I use to convey water to the flushing rim of closets by pipe F the same
pipe may also convey a supply of water to the drain itself to flush the matter from
closets and is supplied from a flushing tank syphonic or otherwise or from any
desired source closets have been thus flushed before but as before stated untrapped
closet pans so formed that there is no opening between them and the wall have not
so been applied, and this combination of my special closet and the parts named I
hold to be novel.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is:
1st The use of one or more untrapped closet pans so formed that they may fit
to wall or otherwise close in the space between closet pan and wall in combination
with the drain pipe C.
2nd The combination of a closet pan as aforesaid and the drain pipe C and a
flushing tank used to flush the same.

page_text: 3rd The use of a syphonic outlet to withdraw the contents of the closets in com-
bination with the closets described wherein they are so formed as to close in the
space usually open between closet and back wall.
4th The use of two or more closet pans as described in combination with a drain
pipe as C with syphonic outlet.
5th The use of a closet pan formed so as to close in the space usually open between
closet and wall having a contracted neck as shewn by dotted lines G the said neck
being of less diameter than the vertical connection by which the closet delivers
itself to drain.
6th The use of the arrangements shewn and described whether flushed by clean
or waste water or without flushing, or their equivalent though differing in con-
formity substantially the same.
