IMPROVEMENTS IN CISTERNS FOR WATER CLOSETS, URINALS AND THE LIKE
Year: 1884

page_text: I FELIX CLEWETT BIDDISCOMBE (of Manchester in the County of Lancaster
Plumber do hereby declare the nature of said Invention for IMPROVEMENTS IN
CISTERNS FOR WATER CLOSETS, URINALS AND THE LIKE, to be as follows:-
My invention relates to cisterns which contain a supply of water for flushing
water closets, urinals, and the like and the object of my Invention is to improve
and simplify the construction of such cisterns so as to obtain a more thorough
"flush," to dispense with flushing valves and at the same time to prevent waste
of water,
"
In performing my Invention I divide the cistern into two compartments by
means of a suitable partition or division. Water is supplied in the usual manner.
to the first of these compartments through the ordinary ball tap and flows through
a small hole in the partition near the bottom of the cistern into the second
compartment, the first compartment is fitted with an overflow pipe as usual:
the closet flush pipe is connected to the long end of a syphon, the short end
of which passes through the side of the cistern preferably about two inches
from the top and is carried down the inside at one end of the second compart-
ment in the opposite and preferably the larger end of the second compartment
I fit a plunger secured to a bent pivoted lever connected at one end to the "wire
pull" from the closet and having a counterpoising weight at the other end which
keeps the plunger out of the water until the pivoted lever is depressed by the
wire pull.
When the pivoted lever is pulled down the plunger is depressed and the level of
the water in the second compartment is thereby raised sufficiently to charge the
syphon and so flush the closet and the flushing continues until the level of the
water in the second compartment has fallen below the short end of the syphon.
A fresh supply of water will flow through the small hole from the first
compartiment and gradually fill again the second compartiment.
The plunger will have been raised by the counterpoise to its normal position
above the level of the water as soon as the pull is taken off.
When an after flush is desired a second syphon of smaller diameter than the
first is employed, the long end being in connection with the long end of the first
syphon and the short end being carried down the inside of the second compartment
a little lower than the short end of the first syphon.

page_text: I FELIX CLEWETT BIDDISCOMBE, of Manchester, in the County of Lancaster,
Plumber, do hereby declare the nature of said Invention for IMPROVEMENTS IN
CISTERNS FOR WATERCLOSETS, URINALS, AND THE LIKE, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to cisterns which contain a supply of water for flushing
waterclosets, urinals, and the like, and the object of my Invention is to improve
and simplify the construction of such cisterns so as to obtain a more thorough
flush," to dispense with flushing valves, and at the same time to prevent waste of
water.
In performing my Invention I divide the cistern into two compartments by
means of a suitable partition or division. Water is supplied in the usual manner
to the first of these compartments through the ordinary ball tap, and flows through
a small hole in the partition near the bottom of the cistern into the second
compartment, the first compartment is fitted with an overflow pipe as usual; the
closet flush pipe is connected to the long end of a syphon, the short end of which
passes through the side of the cistern preferably about two inches from the top and
is carried down the inside at one end of the second compartiment; in the opposite
and preferably the larger end of the second compartment I fit a plunger secured to
a bent pivoted lever connected at one end to the "wire pull" from the closet and
having a counterpoising weight at the other end which keeps the plunger out of
the water, until the pivoted lever is depressed by the wire pull.
When the pivoted lever is pulled down the plunger is depressed and the level
of the water in the second compartment is thereby raised sufficiently to charge the
syphon and so flush the closet, and the flushing continues until the level of the
water in the second compartment has fallen below the short end of the syphon.
A fresh supply of water will flow through the small hole from the first
compartment and gradually fill again the second compartment.
The plunger will have been raised by the counterpoise to its normal position
above the level of the water, as soon as the pull is taken off.
When an after flush is desired a second syphon of smaller diameter than the
first is employed, the long end being in connection with the long end of the first
syphon, and the short end being carried down the inside of the second compartment,
a little lower than the short end of the first syphon.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Fig. 1 is a plan and Fig. 2 a side view partly in section, on the line A B Fig. 1 of
a cistern for flushing waterclosets and the like to which my improvements are
applied. Fig. 3 is a detached view in section of the arrangement for supplying an
after flush of water to the same.
Similar letters refer to similar parts throughout the several views.
In these views, a is the cistern with a partition b; is the stand pipe secured to
the bottom of the cistern and projecting upward into a tube b' which may be
formed with the partition b to isolate the pipe c from the upper part of the cistern';
a dome or cylinder d is passed from above down the tube b' over the stand pipe c;
this dome has secured to its top a screwed spindle d' on which is an adjustable
washer d, that rests on the tube b¹ and supports the cylinder at the desired
height in the cistern; a hollow plunger fis connected loosely to a weighted lever g
pivoted at g' to the cistern; the "wire pull is attached to a lever at y' secured to
the lever g the plunger fis surrounded by a tube b³ formed with the partition b
and it slides on the spindle f'.

page_text: The water supply c is opened and closed by the ball c¹ and tap c², the ball lies
in the recess of the partition b which has a small hole b' through it; h is the
overflow pipe.
The action is as follows:-Fig. 2 of the drawings represents the different parts
in the position they occupy when the cistern is empty; on water being admitted
through the tap c² to the upper part of the cistern it runs off the partition_b,
through the hole b' and fills the lower part of the cistern, as the water rises the
ball c floats and closes the tap c² when the water is about one inch below
the overflow pipe ; the top of the stand pipe c is about half an inch above the
overflow h.
When it is desired to flush the closet, the "wire pull" is drawn down at g² and
the lever g in descending forces the plunger finto the tube 6 and lower part of
the cistern thus displacing a quantity of water which passes upward into the
space between the cylinder d and the stand pipe c; as soon as water begins to run
over and into the pipe c, a syphon is formed and water will flow through c until
the water in the cistern falls to the level of the lower part of the cylinder d;
after the flush has taken place the ball c¹ falls and water begins to fill the cistern
again.
In order to regulate the quantity of water for each flush, I employ a screwed
spindle secured to the top of the cylinder d; on this spindle is a large washer d²
which rests upon the top of the tube b' by screwing the washer & toward the top
of the spindle, the cylinder d rests nearer the bottom of the cistern and consequently
a larger quantity of water will be "syphoned" into the stand pipe when the
wire pull" is drawn.
"
In order to provide for an after flush of water I employ a double pipe or tube l,
which passes over the stand pipe and under the cylinder d; the larger end of this
double tube stands in the water at a lower level than the cylinder & and the inner
end must be lower than the other in order to form a syphon.
After the flush of water has passed to the stand pipe c a small quantity of water
will continue to run through the pipe into the pipe c until the water in the
cistern falls to the level of the outer ends of the pipe and so make an after flush,
the quantity of which depends on the level of the pipe k below the cylinder d.
I do not limit myself to the exact details herein stated as they may be varied or
modified without departing from the nature of my said Invention.
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―
1. The combination of parts forming the improved apparatus for flushing
waterclosets, urinals and the like, substantially in the manner shown and
described.
2. In a cistern for flushing waterclosets and the like the use and application
of the plunger f substantially in the manner and for the purpose shown and
described.
3. The combination of parts for giving an after flush to waterclosets and the
like as described and as illustrated by Fig. 3.
