Improvements in Flushing Cisterns.
1, JOB DEELEY of Phoenix Works Holloway Head in the City of Birmingham,
Plumber's Brass Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that type of flushing cisterns, in which a bell, and stand-
pipe remain stationary, with a plunger working around the stand-pipe, and within the
interior of the bell, which surrounds the stand-pipe, other than at its extreme lower end.
The object of my present invention, is to simplify the construction of, and to
render more efficient in use, the said cisterns, which is an improvement upon Letters
Patent dated the 28th day of October 1881 No. 4725, of which I was the sole
licensee.
The stand-pipe, whose upper and pierced end stands above the top of the cistern,
is made stationary with the flush-box, whose bottom surrounding the said stand pipe,
is sunken. or made into a shallow well, of a little larger diameter than the lip or
lower end of the bell, as herein-after described.
The bell, whose inside crown part is affixed to the top of the stand-pipe, is of
greater diameter at the lower part than at the upper part; and within the said lower
part, a plunger with an excentrically disposed rod, works.
The lower part of the bell is of such greater diameter than the upper part, that the
plunger rod works through the top or crown part of the enlarged part, and is there
connected by a link to the inner end of a lever, fulcrumed to a bracket made on the
top side end of the flush-box or cistern casing; so that by the pulling down of the
said lever, the plunger which surrounds the standpipe, and works within the enlarged
lower part of the bell, is raised, and the water above it, elevated to the top of the
standpipe, which thereby gives the starting to the flush, which removes the air, and
creates a partial vacuum in the down pipe; so that the inside pressure not being
counter-balanced by that of the outside, the water in the cistern is forced up the
interior of the beli down the stand-pipe, and from thence to the closet.
It will be understood that in making the bell of two diameters, the displacement of
liquid in the larger one, will rise to a greater corresponding height in the smaller
one.
The outer diameter of the shallow recess in the bottom of the cistern, has inclined
inner-sided snugs, placed at intermediate distances apart, and upon the inclines of
which, the lip of the bell comes, and when forced home by a screw, through crown of
bell and stand-pipe, the said bell is adjusted centrally with water-spaces between lip
and recess outer circumference.
By setting the mouth of the bell lower, or on a level with the bottom of the
cistern, all water is perfectly drained from the said bottom.
The inlet nose of the ball-cock, is directed to near the bottom of the cistern, then
slightly outwardly.
The cistern is a perfect water-waste preventer, as the exit holes in the stand-pipe,
are higher than the top of the cistern.
Dated this First day of March 1889.

Improvements in Flushing Cisterns.
I. JOB DEELEY, of Phoenix Works, Holloway Head, in the City of Birmingham,
Plumbers Brass Founder 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 :—
This invention relates to that type of flushing cisterns, in which the bell, and stand-
pipe remain stationary, with a plunger working around the said standpipe, and within
the interior of the bell, which surrounds the stand-pipe, other than at its extreme
lower end.
The object of my present invention, is to simplify the construction of, and to
render more efficient in use, the said cisterns, which is an improvement upon Letters
Patent dated the 28th day of October 1881 No. 4725 of which I was the sole
licensee.
The stand-pipe whose upper and pierced end stands above the top of the cistern'is
made stationary, with the flush-box, whose bottom surrounding the said stand-pipe, is
sunken or made into a shallow well, of a little larger diameter than the tip or lower
end of the bell, as hereinafter described.
The bell, whose inside crown part is affixed to the top of the stand-pipe, is of
greater diameter at the lower part, than at the upper part; and within the said lower
part, a iplunger with an excentrically disposed rod, works.
The lower part of the bell, is of such greater diameter than the upper part, that the
plunger rod works through the top, or crown part of the enlarged part, and is there
connected by a link to the inner end of a lever, fulcrumed to a bracket made on the
top side end of the flush box or cistern casing; so that by the pulling down of the
said lever, the plunger which surrounds the standpipe, and works within the enlarged
lower part of the bell, is raised, and the water above it, elevated to the top of the
stand-pipe, which thereby gives the starting to the flush, which removes the air and
creates a partial vacuum in the down pipe; so that the inside pressure not being
counterbalanced by that of the outside, the water in the cistern is forced up the
interior of the bell, down the stand pipe and from thence to the closet.
It will be understood, that in making the bell of two diameters, the displacement
of liquid in the larger one, will rise to a greater corresponding height in the smaller
one.
The outer diameter of the shallow recess in the bottom of the cistern, has inclined
inner sided snugs, placed at intermediate distances apart, and upon the inclines of
which, the lip of the bell comes, and when forced home by a screw, through crown of
bell and stand pipe, the said bell is adjusted centrally, with with water spaces between
lip and recess outer circumference.
By setting the mouth of the bell lower, or on a. level with the bottom of the
cistern, all water is perfectly drained from the said bottom.
The inlet nose of the ball-cock, is directed to near the bottom of the cistern, then
slightly outwardly.
The cistern is a perfect water-waste preventer, as the exit holes in the stand-pipe
are higher than the top of the cistern.
Figure 1 of the accompanying drawings represents in longitudinal vertical section,
a syphon flushing, cistern, and water waste preventer, constructed and arranged
according to my said invention. The said cistern, consists essentially of a fixed bell,
(contracted at its upper part.) wherein a movable piston, operated by a lever, works
around the stand-pipe; 50 that by the turning of the said lever, by a pull, the piston
is raised, and water elevated to the inside crown of the bell, which then flows down
the stand-pipe, and thereby starts the flushing.
Figure 2 represents a like-sectional view as figure 1, but with the piston raised, and
the cistern flushing.
Figure 3 is a transverse vertical section of the said figure 1, taken upon the dotted

page_text: The pulling of the lever f, by the pull j, raises the forked ends f³, and with it the
piston c, which raises the water-in-the-interior-of-the-bell, above the height of the
opening in the stand-pipe, when the said water passes down the interior of
the stand-pipe, and displaces the air within it, and the inside crown of the bell,
thereby creating a vacuum, or a partial vacuum, and starts the flushing until the
water within the flush box has been emptied.
In the modification figure 6 a is the flush box, b the stand-pipe, e is a fixed bell, of
two diameters, c is a piston, raised by a single piston rod d, passed through a hole or
gland e, made within the shoulder e, formed at the junction of the contracted upper
part, with expanded lower part.
The lip of the bell has a snug es, depending below it, and adapted to come against
fixed snugs a³, disposed within the shallow-well at, at the bottom of the cistern; so
that on the connecting of the bell to the stand pipe, it is prevented from turning.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
First: In a piston worked syphon flushing cistern, making a fixed bell of two
diameters viz. the upper part of a less diameter, than the lower part, substantially
as described and set forth.
:
Secondly The combination with an interiorly working and movable piston, and
open top stand pipe, of a fixed bell of two diameters, as described, and set forth.
ThirdlyWorking or passing the piston rod or rods through the shoulder att he
junction of the said two diameters, as set forth, whereby a water joint is produced.
Fourthly The combination with a stand-pipe and fixed bell, of a guide and
stop g. g² substantially as set forth in figures 1, 2, and 3.

page_text: The construction and arrangement of the parts of flushing cisterns, and
the piston picking-up means, as described and set forth in the several figures of the
drawings.
Dated this 29th day of November 1889.
