IMPROVEMENTS IN OR ADDITIONS TO FLUSHING CISTERNS
Year: 1885

page_text: I, JOB DEELEY of Fordrough Street, Birmingham in the County of Warwick,
Manufacturer do hereby declare the nature of said invention for "IMPROVEMENTS
IN OR ADDITIONS TO FLUSHING CISTERNS," to be as follows:-
Flushing Cisterns of the ordinary construction are so arranged, that no provision
is made for holding back a portion of the flush, in order to seal the joint, or to
allow a stratum of water to lie at the bottom of a pan or basin of a Watercloset
or other sanitary trap-Thus in pneumatic or syphon flushers, the water passes
with such velocity into the pan of a Closet, that the impetus thus acquired, leaves
no water in the pan, but is passed away down the outlet-It is desirable and
necessary to obtain a powerful flush in order that the soil in the pan shall be
completely removed, while at the same time holding back a portion of the water
which is left in the pan.
Now my invention consists in so arranging pneumatic or other flushers (particularly
the former) for water closets and the like, that an after-flush is obtained; that is,
a portion of the flush is held back until the main flush is over, when the said after
flush is allowed to slowly dribble or pass into the pan of the closet, and there rest.
I will describe my invention in connection with a "Deeley" or pneumatic
syphon flusher.
The down pipe leading to the delivery pipe is surrounded or encircled by an
annular jacket or casing which forms a chamber, wherein the after flush is stored-
This annular storage chamber is open at top, and closed at bottom, and extends
from the bottom of the down pipe to near the inside top of the bell-The said.
closed bottom is provided with a small hole which passes from the chamber into
the inside of the down pipe which leads to the delivery pipe.
On flushing, the water from the flush box passes up the inside of the bell, which
surrounds the storage chamber, through the aperture or apertures in the top of the
down pipe, and over the open top of the storage chamber, filling the said chamber
with water to constitute the after flush.
The main flush after thus having passed precipitously into the pan of the closet,
passes onward to the drain, without leaving sufficient water in the pan to form the
necessary seal or trap-The water now from the storage chamber slowly dribbles
through the small hole leading into the down pipe and from thence the water
passes to the pan, where it lies to form the seal.

page_text: The jacket which comes inside the bell and surrounds the downpipe, may surround
the bell, instead of the downpipe; the water contained therein passing through a
pipe into the down pipe.
When I employ no reserve or after flush chamber, I make a small hole a little
above the lip of the bell, to admit air in order to stop the pneumatic action of the
flusher at a particular time; that is, at a time when the major portion of the water
in the flush box has been withdrawn. Thus on flushing a pan, the water is forced
precipitously by the pressure of the atmosphere, through the syphon arrangement,
until the water in the cistern is lowered to the hole in the side of the bell, when
air is admitted to the inside of the bell which instantly reduces the flush by
partially destroying the pneumatic action, thus allowing what water remains in
the cistern, to flow slowly down the downpipe to the pan of the closet..
My invention is applicable to cisterns with both movable and fixed bells and to
.certain other forms of cisterns which are well known.

page_text: I JOB DEELEY of Fordrough Street Birmingham in the County of Warwick,
Manufacturer, do hereby declare the nature of said invention for "IMPROVEMENTS
IN OR ADDITIONS TO FLUSHING CISTERNS," and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Flushing cisterns of the ordinary construction are so arranged, that no provision
is made for holding back a portion of the flush, in order to seal the joint, or to
allow a stratum of water to lie at the bottom of a pan or basin of a water-closet
or other sanitary trap. Thus in pneumatic or syphon flushers, the water passes
with such velocity into the pan of a closet, that the impetus thus acquired, leaves
no water in the pan, but is passed away down the outlet. It is desirable and
necessary to obtain a powerful flush, in order that the soil in the pan shall be
completely removed while at the same time holding back a portion of the water
which is left in the pan.
Now my invention consists in so arranging pneumatic or other flushers (par-
ticularly the former) for water closets and the like, that an after flush is obtained;
that is, a portion of the flush is held back until the main flush is over, when
the said after flush is allowed to slowly dribble or pass into the pan of the closet,
and there rest.
I will describe my invention in connection with a "Deeley" or pneumatic syphon
flusher,
The down pipe leading to the delivery pipe is surrounded or encircled by an
annular jacket or casing which forms a chamber, wherein the after flush is stored.
This annular storage chamber is open at top, and closed at bottom, and extends
from the bottom of the down pipe to near the inside top of the bell. The said
closed bottom is provided with a small hole which passes from the chamber into
the inside of the down pipe which leads to the delivery pipe.
On flushing, the water from the flush box passes up the inside of the bell, which
surrounds the storage chamber, through the aperture or apertures in the top of the
down pipe, and over the open top of the storage chamber, filling the said chamber
with water to constitute the after flush.
The main flush after thus having passed precipitously into the pan of the closet,
passes onward to the drain, without leaving sufficient water in the pan to form the
necessary seal or trap. The water now from the storage chamber slowly dribbles
through the small hole leading into the down pipe and from thence the water
passes to the pan, where it lies to form the seat.
The jacket which comes inside the bell and surrounds the down pipe, may
surround the bell, instead of the down pipe; the water contained therein passing
through a pipe into the down pipe.
When I employ no reserve or after flush chamber, I make a small hole a little
above the lip of the bell, to admit air in order to stop the pneumatic action of the

page_text: flusher at a particular time; that is, at a time when the major portion of the
water in the flush box has been withdrawn. Thus on flushing a pan, the water is
forced precipitously by the pressure of the atmosphere, through the syphon arrange-
ment, until the water in the cistern is lowered to the hole in the side of the bell,
when air is admitted to the inside of the bell which instantly reduces the flush by
partially destroying the pneumatic action, thus allowing what water remains in
the cistern, to flow slowly down the down pipe to the pan of the closet.
My invention is applicable to cisterns with both movable and fixed bells and to
certain other forms of cisterns which are well known.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which the same is to be performed.
Figure 1 represents partly in vertical section, combined bell and downpipe of a
pneumatic or syphon flusher, provided with an after flush or storage chamber,
constructed according to my invention. Figure 2 is a complete section of the same,
and figure 3 is a part section and part elevation, showing the downpipe in elevation
with the after flush store chamber and bell in section. Figure 4 is a plan and part
section of the underside of figure 1 on the dotted lines A. B.
:
The same letters of reference indicate corresponding parts in the several figures
of the Drawing.
a is the down pipe leading to the delivery pipe passing to the closet, and which
said downpipe is surrounded or encircled by an annular jacket or casing b wherein.
the after flush, or a quantity of water to form the seal in the pan of a closet is
stored. This annular storage chamber is open at top, and extends near to the
inside top of the bell c; while the lower closed part thereof is connected, to a
shoulder at a³, near the flush holes at the mouth or valve entrance of the down-
pipe. The said closed bottom of the after flush or store chamber is provided with
a small hole d which passes from the chamber into the inside of the downpipe
which leads to the delivery pipe. The downpipe and bell are connected together
by the screw e, so that on the bell being picked up by its trunnion arms, the bell,
downpipe and after flush chamber are raised together.
On flushing, the combined bell and downpipe or after flush arrangement is raised
in the usual way by means of the trunnion arms, so as to allow the lower or necked
portion a of the downpipe a to be raised from the valve seat, wherein it rests and
seats itself; water then flows momentarily through the openings a¹ so as to cause
the initial flush for creating a rarification of the air in the downpipe, thus causing
the water in the cistern to rise up the inside of the bell through the holes a³ in the
downpipe, over the open top of the after flush storage chamber, and filling the said
chamber with a portion of the water constituting the flush.
The main flush after having passed precipitously up the inside of the bell, through
the openings in the top of the downpipe, and down the downpipe and delivery
pipes into the pan of the closet, then passes onwards to the outlet or drain pipe,
without as a rule leaving sufficient water in the pan or closet to form either the
necessary seal or trap, or to leave the necessary water that should be left in the
bottom of a pan. The water from the storage chamber b now slowly passes or
dribbles through the small hole d, and from thence passes to the pan or basin of
the closet to form the necessary seal, or water accumulation, according to the
character of the closet used.
Figure 5 represents a modification of my invention in which the after flush
chamber instead of surrounding the downpipe is made to surround the inside of
the bell, and the after flush water contained therein passes from the said jacket or
after flush store chamber through a pipe leading from the said chamber to the
inside of the downpipe.
a is the downpipe; b is the after flush store chamber, c is the bell and d is a pipe
leading from the store chamber to the inside of the downpipe, so that on water
passing up the inside of the bell, or rather the jacket or chamber inside the bell,
fills the chamber with water which is slowly given out through the pipe d.

page_text: 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
First. Combining with, and surrounding the downpipe or downpipes of flushing
cisterns, (whether the bell, be fixed or movable) an after-flush chamber or vessel,
in the form of an outer jacket or casing, wherein water is kept back and stored up
from the main flush, and which said water afterwards allowed to slowly flow or
pass therefrom, through a small hole leading into the downpipe, and situated at or
near the closed bottom of the chamber, substantially as described and illustrated
in figures 1, 2, 3 and 4 of the accompanying Drawing.
Secondly. Forming or making within the inside of the bell or between a combined
bell and downpipe an after flush chamber or vessel, wherein water is stored and
allowed to be slowly given out through a hole or pipe leading into the downpipe,
after the main flush bas passed away, substantially as described and set forth in
figure 5.
