PROVISIONAL SPECIFICATION.
Improvements in Syphon Cisterns or Water Waste Preventers.
JOHN EDWARD ROGERS of Sycamore Road, Smethwick in the County of Stafford,
Engineer, do hereby declare the nature of this invention to be as follows:-
Improvements in Syphon Cisterns or Water Waste Preventers.
The body of the Cistern is made of suitable shape to receive the working parts
necessary to carry out my Invention.
The Syphon for emptying the Cistern when full of water would be designed and
attached to the Cistern as follows, one leg of the Syphon goes down inside the cistern
and has its end expanded into a cylinder which cylinder has projecting down its
centre a hollow, sleeve. The Syphon cylinder is made with a swell or bulge all round
at its Junction with the Syphon pipe to allow clearance for the water when the
Syphon cylinder piston has charged the syphon Fall Pipe. The Syphon cylinder
Piston has also a sleeve that works over the sleeve in the syphon cylinder when the
syphon cylinder Piston is used for charging the syphon to empty the cistern.
The syphon cylinder Piston is worked by means of a lever arranged on the upper
part of the cistern attached to a connecting Rod. The fall Pipe leg of the Syphon
is brought down outside the cistern and fastened to a bracket or Plate cast solid with
body of cistern.
The action of the cistern is as follows-The Syphon cylinder Piston is lifted by the
ordinary lever and Rod arrangement as mentioned forcing the water through the
syphon into the fall Pipe and starting the cistern syphoning. The syphon cylinder
Piston passes up over the bulged part in the syphon cylinder. The flow of the water
holding the syphon cylinder Piston up allows the water to flow freely past it through
the bulged part of the syphon cylinder and down the fall Pipe till the cistern
is emptied, when the syphon cylinder Piston returns to its position for again
charging the Syphon.
These improvements may be modified in design without departing from the nature
of my. said invention.
COMPLETE SPECIFICATION.
Improvements in Syphon Cisterns or Water Waste Preventers.
JOHN EDWARD ROGERS of. Sycamore Road, Smethwick, in the County of Stafford,
Engineer 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 :-
Figures 1, 2 and 3 of accompanying Drawings shew sectional elevation, Plan and
end view of cistern constructed according to my invention.
Like letters shew the like parts in each Figure.
A is main body of cistern, B the cistern cover, ( the combined syphon and
charging cylinder, C₁ charging cylinder dip Pipe, D Syphon Charging Disc of
Piston Charging Disc Rod, F Side Radius Links, G main lever for putting
cistern in operation.
The action of the cistern is as follows:-Supposing the cistern to be charged with
water through the ball tap Ka downward movement is given to the outward end of
the lever G causing the Disc D to rise in the Syphon Cylinder C and forcing the
water it contains up into the Syphon and starting the same Syphoning, which
Syphoning continues till the water in the cistern is exhausted.

page_text: The Dip pipe C¹ prevents the Syphon from stopping till the cistern is emptied.
The enlarged space in the upper part of the main syphon cylinder is for the
purpose when the Disc D, is lifted up into it, in charging the Syphon (to allow the
water to flow freely round it till the cistern is emptied.
The design of this cistern may be modified without departing from the nature of
my 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 :-
In a Waste Water Preventer, the Syphon C with its dip pipe C and clearance
space round top of cylinder C in combination with Disc D working as shewn and
described.
