1, WALTER WHEELER trading as John Wheeler and Son, of Railway
Foundry, Langley, near Birmingham, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to water-waste-preventing siphon cisterns, which are
generally used in connection with water closets and urinals or the like.
The object of this invention is to provide a cistern which will operate more
readily than those.commonly in use.
Within a cistern of suitable shape 1 fit an oval chamber, which is open at the
top and has several holes in the bottom, one placed centrally within the chamber
wherein to fix a standpipe which when fixed projects through the bottom of the
said cistern which is bored to receive it. The projecting. part is screwed for the
purpose hereinafter described.
The other holes are arranged in convenient positions for the purpose hereinafter
described. The standpipe has a flange or collar upon same, larger in diameter
than the hole in the said chamber, so that when the standpipe is secured by a nut
being traversed along the said screwed part of same until it bears against the
underside of the cistero, the standpipe and the oval chamber are firmly fixed
together.
The said oval chamber is arranged so that there is a space between the inside of
the cistern and the bottom of the oval chamber.
Upon the inside of this chamber, and covering the standpipe, I then place a
dome, which is shaped suitably at the top, and left open at the botton, which part
is exactly the same shape as the chamber and within which it can be freely moved
up and down by means of a lever which is fitted to same by lugs or other convenient
attachments.
This lever is provided with a fulcrum by shaping the sides of the cistern to
receive arms which project from same.
The cistern is filled through a ball tap arranged within same.
By depressing the lever the dome is raised nearly to the top of the oval chamber,
and a vacuum is set up, by this action, within the dome, and the contents of the
cistern siphons out, down the standpipe and through an outlet pipe attached to
same. The said holes in the bottom of the oval chamber allow the free egress of
the water from the cistern into the dome.
My invention is capable of numerous modes of application without departing
from the principle thereof.
Dated this 20th day of August. 1896.

page_text: I, WALTER WHEELER, of Railway Foundry, Langley, near Birmingham,
Engineer, do hereby declare the nature of this invention and in what manuer the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to water waste preventing siphon cisterns, which are
generally used in connection with water closets, urinals & the like. The object
of this invention is to provide a cistern which will operate more readily than those
commonly in use.
Within a cistern of suitable shape, I fit an oval chamber which is open at the
top, and has several holes in the bottom one placed centrally within the chamber
wherein to fix a standpipe, which, when fitted, projects through the bottom of the
said cistern, which is bored to receive it, and is screwed in that part for the
purpose hereinafter described.
The other holes are arranged in convenient positions for the purposes hereinafter
described.
This standpipe has a flange or collar upon same, larger in diameter than the hole
in the said chamber, so that when the standpipe is secured by a nut being traversed
along the said screwed part of same, until it bears against the underside of the
cistern, the standpipe and the oval chamber are firmly fixed together.
The said oval chamber is arranged so that there is a space between the inside of
the cistern and the bottom of the oval chamber.
Upon the inside of this chamber, and covering the standpipe, I then place a
dome, which is shaped suitably at the top, and left open.at the bottom, which part
is exactly the same shape as the chamber and within which it can be freely moved
up and down by means of a lever which is fitted to same by lugs or other
convenient attachments. This lover is provided with a fulorum by shaping the sides
of the cistern to receive arms which project from same. The cistern is filled
through a ball tap arranged within same.
By depressing the lever the dome is raised nearly to the top of the oval chamber,
on releasing the lever the dome falls by its own weight forcing the water up the
'dome & down the standpipe starting the syphon emptying the contents of
the cistern through the said holes in the bottom of the oval chamber & down the
standpipe and through an outlet pipe attached to same.
My invention is capable of numerous modes of application without departing
from the principle thereof.
My invention may be more readily understood by reference to the accompanying
drawings.
Fig. 1 shews a view of the cistern with a portion of the front broken away, both
of the outer covering a and the oval chamber b, and the dome c, to shew the
various parts in position. The standpipe d, can be seen within the dome, and one
of the holes b 1, in the bottom of the oval chamber is shewn underneath the dome.
The lever e, is shewn attached to the dome.
Fig. 2, shewe a section of the invention with the moveable parts c, and e, in their
normal positions.
The chamber b, is shewn with the holes 6 1.
The flange, on the standpipe d is shewn, and the screwed part of the
standpipe g, together with the nut h, are shown in position.
The said ball tap is not shewn in the drawings as it does not form any part of
the novelty of my invention.

page_text: Fig. 3 is a section of the invention shewing the movable parts-the dome c and
the lever e, when the siphon is working, the arrow heads indicating the egress of
the water contained in the cistern down the standpipe d, as the dome descends.
Having now particularly described aud ascertained the nature of my said
invention, and in what manner the same is to be perforined, I declare that what I
claim is :-
In syphon cisterns the employment of a dome in which the waterways of
the shape shewn in the drawings herewith and substantially as herein set forth.
