Improvements in Waste Preventing Syphon Cisterns.
I, WALTER WHEELER, trading as John Wheeler and Son, of Langley near
Birmingham, Ironfounder, 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 consists of a water waste preventing cistern for flushing water
closets, urinals or the like, and the novelty of which consists of a plunger working
in an horizontal position in a cylinder or chamber fixed upon the bottom of a
cistern either on the interior or exterior as hereinafter described, the said plunger
being actuated by means of a lever to which it is articulated, and forcing up the
water contained in the cylinder over the top of the interior of an angular or other
shaped syphon thus creating a vacuum therein and producing the desired flush of
the water from the cistern to an outlet pipe connected to the syphon, and in a more
efficient way than heretofore in such appliances, as hereinafter described.
An oblong box-like casting forming the cistern, open at the top and being
provided with a hole at the bottom for an outlet pipe is arranged to receive the
syphon and horizontal cylinder, and which with the plunger is then duly placed in
proper position, and the syphon and cylinder are fixed firmly to the bottom of the
cistern in any suitable way, and the syphon is arranged in connection with the
cylinder and the outlet pipe herein before mentioned. Then, one arm of a lever,
which is provided with 3 arms, for the purpose hereinafter described, is articulated
with the plunger, which has a lug of suitable shape upon same for that purpose, and
by means of a link attached thereto. The lever is then attached to a bearing or
fulcrum arranged on the upper exterior extremity of the syphon upon which the
lever may be worked to start the action of the plunger. Another of the said arms
of the lever is provided with a cord or chain with which to depress the lever when
starting the action of the plunger, and another arm has a weight thereon and
arranged so as to counterbalance and maintain the working parts of the plunger
and its attachments in their normal positions when the syphon is not in operation.
An aperture in the cylinder through which the plunger works serves the purpose
also of admitting the water contained in the cistern into the cylinder when the
syphonage is taking place.
An ordinary ball valve tap governs the supply of water to the cistern and an
overflow pipe is arranged as usual, but these to prevent confusion are not shewn
in the drawings and they do not form any part of the novelty of this invention.
The whole of the cistern is suitably covered with a lid or cover.
The invention may be more clearly understood by reference to the accompanying
drawings.
Fig. 1. shews a section through the cistern a. The cylinder c in connection with
the syphon and the lever d attached to same at the fulcrum e.
The link shews the attachment of the lever to the plunger g, and h shews the
aperture through which the plunger operates and through which the water in the
cistern passes when the syphonage is taking place. The dotted line k indicates
the normal water level in the cistern. The dotted lines shewing the lever indicates
the second position of same, that is, the position of the lever and its attachments
when it is pulled down to start the action of the plunger. The cover i is shewn in
position.
Fig. 2. is a plan of the cistern with the cover removed.

page_text: Fig. 3. represents a section of the form of constructing a cistern with the
cylinder c on the exterior of the bottom of the cistern a, and shews the lever
down.
Fig. 4 is a transverse section of same.
The letters indicating the parts shewn correspond in all the figures shewn.
It is evident that the details may be varied without departing from the principle
of the invention.
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:
:-
1. In constructing water waste preventing cisterns the employment of horizontal
cylinders on the interior or exterior of same as herein before described.
2. The combination of the horizontal cylinder c and the plunger g. with a
syphon, and the employment of the lever d attached to the syphon in the manner
as above described and substantially as set forth herein.
Dated this Third day of September, One thousand eight hundred and
ninety-four.
