COMPLETE SPECIFICATION.
Improvements in Closets and Flushing Apparatus.
I, MOSES JAMES ADAMS, Engineer, Sanitary Works, 72, Park Lane, Leeds, 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 improvement consists in the special form of a closet and seat and an
arrangement for flushing the same, which arrangement may also be used with
urinals in a similar manner. The object of this flushing arrangement is to
cause the flush to take place when by reason of use, the apparatus to be flushed
requires such a discharge of water to it, whereas in the automatic tanks now
commonly employed in school and other work, the discharge of the said tank
takes place at a certain rate per diem according to the feed from tap, and is
therefore altogether independent of the proper requirements of the case, and
much water is thereby consumed needlessly.
As will be seen the apparatus though forming an integral part of the present
invention may yet be applied to any single or multiple closet or to a urinal or any
other apparatus which requires to be flushed out periodically. The closet AA,
I show however, is one which formed the subject of an earlier patent, but which
in its horse shoe seat T and seat connection S has novel features, it will be seen
that I form a skirting U of the ware in which closet is made and that the opening
for flush pipe V is formed therein to secure greater strength than where the
ordinary nozzle is used. The seat I form as a horse shoe and hinge it by staples
or eye fixed in the skirting U of closet. This closet may be used either with or
without the flushing arrangement. As shewn the flush is obtained by the liquid
rising in the pipe W and strap X under closets flowing through a suitable
opening M into cylinder N. This cylindrical vessel N has an inner cylinder or
compartment O, to which is connected an air pipe L, so that when liquid enters O,
the air therein is displaced and passes up pipe L into cistern Y. This cistern
has a ball cock Z, which feeds it partly full of water, then closes off when the
float of ball cock shuts it off. Over the pipe L there is a cap K which is attached
on lever J of feed cock H. This cock has a reverse action, so that while the
lever and cap K are down, the cock is shut off, but when the air from 0 passes
up L it cannot get away, and consequently its pressure lifts cap K and the lever J,
so that water is fed into the cistern by H, and flowing over syphon F" sets up
syphonic action, the discharge of the cisterns contents then being made to closets:
then the water flowing into vessel N by passage M overflows syphon D, which
sets up its discharge, emptying the contents of the vessel N to the drain pipe E.
The closets being used again sufficient water will again flow to N, air will lift K
and the flush will be repeated and the arrangement may equally well be applied
to latrines, single closets or urinals.
In some cases where it is inconvenient to transmit air from vessel N, I allow
the water rising therein to lift a ball valve as shewn at Fig. 2 A being the ball
valve, A¹ the ball which rises and falls as the vessel N is filled or emptied; when
filled by overflow through M it rises and turns on water to cistern Y by pipe B,

page_text: the said pipe being in connection with a water supply, the vessel N is emptied by
the syphonic D as before described.
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:-
1st. The use of a vessel into which overflow liquid from closet or urinal shall
enter displacing the air therefrom, the said air acting upon a float and cock to
cause water to feed to flush tank for the purpose of discharging the same.
2nd. The use of a vessel N with inner division or compartment O, inlet M, and
withdrawing syphon D, and air pipe L for the purposes herein set forth.
3rd. The combination of the vessel N with an overflow from closet or urinal,
the air pipe L and the cistern Y, the latter having a feed supply to same
actuated by the lifting of lever and cap K by air pressure.
4th. The use of the vessel N with a ball cock as shewn at Fig. 2 and the
withdrawing syphon 1) or equivalent in combination with a closet or urinal and
a flush tank.
5th. The use of the closet shewn with skirting U the same having vertical
opening for flush pipe therein and being fitted with hinges or staples for
seat.
6th. The use of a horse shoc seat as shewn in combination with a closet the
same having a back which shall fit flush up to wall.
7th. The use of the different appliances herein shewn and described or their
equivalent, though differing in conformity, substantially the same.
Dated this 20th day of February 1899.
