WASTE WATER PREVENTER referred
Year: 1885

page_text: HENRY YULL, 168 3rd Avenue, Queen's Park Estate, Paddington, London,
Plumber, Gas & Hot water fitter, &c I do hereby declare the nature of my
invention for the WASTE WATER PREVENTER referred to above to be as
follows:-
Small tank or cistern containing an air drum with a syphon inside which traps
the air, and to which is attached a sinall air pipe, to the top of the drum, carried
through the top of the preventer to any suitable place required: with a press
button tap at the end. By touching the press button it will allow the air to
escape from the drum, and the water follows immediately, and starts the syphon.
The water will continue to flow till the tank is empty. The action therefore is
solely by means of compressed air, and no levers, chains, or other mechanical
appliances are required. To be made of galvanised iron or other suitable material.

I, HENRY YULL, of 168, 3rd Avenue, Queen's Park Estate, Paddington, W., in
the county of Middlesex Plumber 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 the construction of a cheap, simple, and efficient water
waste preventer applicable for use in water closets, urinals, flushing tanks cisterns
or generally where a measured flush of water or other liquid is required.

page_text: Referring to the accompanying sheet of drawings and to the letters of reference
thereon indicated, I construct a cistern or tank A of suitable form and capacity and
fit a supply valve B to the same, controlled by a float or ball C and lever D as usual.
I fit an air drum E to the cistern or tank A which drum may be perforated at F
at its union with the cistern or tank A, or it may be placed in the same and
supported by brackets, legs, stays, or otherwise so as to leave a space between it
and the bottom of the cistern.
Inside this drum E I place a ring or annulus G and within the latter a syphon H
communicating by its long leg with the object or article to be flushed.
A pipe I from the air drum E communicates with a push J or with a self-closing
or other valve or ordinary tap.
I have indicated a push J having a disc or plate K closing on an elastic
seating L, a spring M being interposed between the disc or plate K and the casing
or chamber N of the push communicating with the pipe I.
I do not, however, bind myself to this push or to any particular form of valve,
cock, or tap for admitting air to the pipe I and so to the drum E.
As the ball valve sinks, water (or disinfectant or other liquid) is admitted to the
tank A until the rising of the ball closes the supply valve.
To flush the closet or other article I press the push J, or open its equivalent the
cock, valve, or tap.
Air is discharged from the drum E, which starts the syphon H, causing it to
discharge liquid from the tank or cistern A owing to the escape, by means of the
push, valve, or cock, of the air previously compressed in the drum E by the water
or liquid entering the tank or cistern A.
:.
As the ball sinks, water or liquid is again admitted to the tank or cistern A, or
the ball may be held by any suitable means until the flush is complete, and then
released.
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 In a flushing tank or cistern the employment of an air drum containing or
in combination with an annulus or ring enclosing a syphon, and of a pipe
communicating with the said drum and of a suitable push valve, cock, or tap,
to relieve air pressure in the said air drum, (the air being previously compressed
by the inflowing water or liquid), and so start the syphonage substantially as
described.
2nd The general arrangement and construction of waste liquid preventer, sub-
stantially as described and illustrated by the accompanying drawings.
Dated this 12th day of February 1886.
