Improvements in or relating to waste water Closet Apparatus.
Year: 1899

page_text: I, CHARLES GREENHALGH, 9, Whiteacre Road, Ashton-under-Lyne, Inventor,
do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements in or relating to waste water closet
apparatus, the object being to effectively utilize waste water or other liquid for
flushing purposes.
In carrying out my. invention I provide a cistern or reservoir adapted to receive
the required liquid or waste water. An overflow is provided which allows the
liquid or waste water, when the cistern or reservoir is full, to flow over the desired
part and thence to the outlet, thus tending to prevent blocking or stoppage and
also preventing smell. The cistern or reservoir is provided with a suitable
valve for giving what is known as a flush when required. A suitable seat and
passage are provided and the length or height of the passage may be adjusted in
any convenient manner, an aperture being arranged so as to allow matter to pass
of such a size as not to obstruct the drain or outlet pipe.

Improvements in or relating to waste water Closet Apparatus.
I, CHARLES GREENHALGH, 9, Whiteacre Road, Ashton-under-Lyne, Lancashire,
Gentleman, 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 improvements in or relating to waste water closet
apparatus, the object being to effectively utilise waste water or other liquid for
flushing purposes.
In carrying out my invention I provide a cistern or reservoir adapted to receive
the required liquid or waste water. An overflow is provided which allows the
liquid or waste water when the cistern or reservoir is full, to flow over the desired
part & thence to the outlet, thus tending to prevent blocking or stoppage, and
also preventing smell. The cistern or reservoir is provided with a suitable valve
for giving what is known as a flush when required. A suitable seat and passage
are provided and the length or height of the passage may be adjusted in any
convenient manner, an aperture being arranged so as to allow matter to pass of
such a size as not to obstruct the drain or outlet pipe.

page_text: My apparatus may be placed at any convenient distance below the floor of the
closet to admit of a ready means of access to the various parts of the cistern,
closet pan, funnel, intercepting trap or outlet pipe, and as a further safeguard
against blockage I provide two hand hole cleaning covers or doors in the inter-
cepting trap; the water valve in cistern may be operated from the closet either
by a handle coupled direct to the valve spindle or by means of a chain and hand
loop overhead passing over a pulley and thence down to the valve spindle, the
lift of cistern valve can be regulated or adjusted by means of a pin as shown or
an adjusting nut may be used, I employ a metal valve and seat in the cistern
and fit the lower or bed portion of valve with a soft metal, leather, or composition
washer to obviate leakage. The outlet pipe to sewer is of a taper design, giving
an increased diameter or bore at its connection with the main drain or sewer.
At the bottom of closet pan a water cavity or dish is formed, this acts as a
softening or preparation chamber for any deposit which may pass from the funnel
after the valve of water cistern has closed or the supply or flush of water has been
inadequate to wash away. In the accompanying drawing Fig. 1 shows a longi-
tudinal section of my apparatus and Fig. 2 gives a cross section of closet pan
(showing the cavity or dish referred to as a preparation chamber) through
line A, B, description of Fig. 1. C closet pedestal, D shaft, E funnel, F closet
pan, G waste water overflow, H flush water inlet, J water cistern, J¹ waste water
supply pipe, K valve and seat, L handle or loop to open valve K, M pin to adjust
lift of valve K, N floor of closet, 0 intercepting trap, P examination doors,
R outlet pipe.
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. A cistern or reservoir to be used for the purpose of a closet water supply,
constructed and applied in the manner described herein.
2. The method or manner of applying an overflow in the cistern and shaft, as
shown in the drawing and herein described.
3. The construction and application of the valve in water cistern in the manner
and for the purpose herein named.
Dated this 3rd day of September 1900.
