page_text: LETTERS PATENT to John Bailey Denton of Whitehall Place in the City of
Westminster, Civil Engineer, and George Butler of 2 Ivy Cottage, Acton
Green Road, Turnham Green, in the County of Middlesex, Engineer, for an
invention of "IMPROVEMENTS IN APPARATUS FOR FLUSHING SEWERS AND
OTHER SIMILAR PURPOSES."
PROVISIONAL SPECIFICATION left by the said John Bailey Denton and
George Butler at the Office of the Commissioners of Patents on the
29th March 1882.
JOHN BAILEY DENTON of Whitehall Place in the City of Westminster Civil
Engineer, and GEORGE BUTLER of 2 Ivy Cottage, Acton Green Road, Turnham
Green in the County of Middlesex, Engineer, "IMPROVEMENTS IN APPARATUS
FOR FLUSHING SEWERS AND OTHER SIMILAR PURPOSES.
"
The object of this apparatus is to collect waste or other water, until a sufficient
quantity is stored to effectually flush a sewer or pipe or other channel or way as
the case may be and thereupon for the said purposes to automatically discharge
such water in a continuous stream.
For this purpose we provide a tank or reservoir wherein waste or other water is
collected. Within this tank or reservoir is a syphon, the shorter leg of which
reaches not quite to the bottom of the tank or reservoir, whereas the longer leg
extends downward into a lower chamber or space. In connection with this syphon,
we provide means whereby on the tank or reservoir becoming nearly full, a valve
is automatically opened that admits water into the longer leg of the syphon thereby
creating a partial vacuum and causing water to pass over from the shorter leg thus
setting the syphon in operation until the contents of the tank or reservoir are
withdrawn to the level of the lower end of the shorter syphon leg. A. convenient
automatic valve arrangement consists of an open top vessel arranged within the
tank or reservoir and connected by a trap to the longer leg of the syphon. Within
this vessel is pivotted a tipping.box or bucket connected to a valve that normally

page_text: closes communication between the interior of the vessel and the trap. When water
accumulates in the tank or reservoir sufficient to overflow the top of the vessel
above mentioned, the tipping box or bucket becomes charged and is caused to tilt
thereby opening the valve, discharging water and starting the syphon as above
explained, after which the tipping box or bucket automatically resumes a position
that closes the valve and sets the apparatus in readiness to again start the syphon
when the tank or reservoir shall have become sufficiently charged.
In one modification we use two connected tipping boxes or buckets so arranged
to turn about a pivot or axis that when one is in position to receive water for
starting the apparatus the other upside down below it, and as the one descends
to discharge, the other ascends to take its place above.
It will be evident that flushing apparatus provided with syphons set in action
by admission of liquid to the longer leg as above set forth may be constructed
in various forms without departure from the peculiar characteristics of our
invention.

JOHN BAILEY DENTON of Whitehall Place in the City of Westminster Civil
Engineer, and GEORGE BUTLER,. of 2 Ivy Cottage, Acton Green Road, Turnham
Green, in the County of Middlesex, Engineer. IMPROVEMENTS IN APPARATUS
FOR FLUSHING SEWERS AND OTHER SIMILAR PURPOSES
The object of this apparatus is to collect waste or other water or liquid mixed or
not with solid floating matter until a sufficient quantity is stored to effectually
flush a sewer or pipe or other receptacle, channel, or way as the caso may be and
therefore for the said purpose to automatically discharge such water in a continuous
stream until emptied.
For this purpose we provide a cistern, tank, or reservoir wherein waste or other
water may be collected. Within this cistern tank or reservoir is a syphon the
shorter leg of which reaches not quite to the bottom, whereas the longer leg
extends downwards into a lower chamber or space. In connection with this syphon
we provide means whereby on the cistern, tank, or reservoir becoming nearly full,
a valve is automatically opened that admits water into the longer leg of the syphon
whereby a partial vacuum is created which causes the water to pass over the crown
or top of the syphon and to set the syphon in action which draws the water out
of the cistern, tank, or reservoir down to the level of the mouth or end of its
shorter leg.
A convenient automatic valve arrangement consists of a vessel so arranged as to
receive the water as it overflows the cistern, tank or reservoir. This vessel is
connected by a trap with the longer leg of the syphon. Within this vessel is
pivotted a tipping box or bucket connected with or acting upon a valve that
normally closes the communication between the interior of the vessel and the
trap.
When water accumulates in the cistern, tank or reservoir sufficient to flow over
the top of the vessel above mentioned into the tipping box or bucket, that box or
bucket becomes charged and is caused to tilt thereby opening the valve with
which it is connected or upon which it acts, and starting the syphon as above
explained, after which the tipping box or bucket automatically resumes its
norinal position and closes the valve and so sets the apparatus in readiness to
again start the syphon when the tank or reservoir shall have become sufficiently
charged.
Referring to the accompanying sheet of drawings Figure 1 is a vertical section
of a flushing cistern or tank and apparatus according to our invention. Fig. 2 is
a section at right angles to Fig. 1 Fig. 3 is a half plan with the cover of the tank
removed and, Fig. 4 is a similar view with the cover in position,
A is the tank with the cover or lid B. In this lid is an opening into which is
dropped a trap C with a loose grid or cover D, this trap C can be lifted out bodily
to be cleaned or to leave a wide opening for access to the interior of the tank.
E is a ventilator.
The water or liquid entering the cistern or tank accumulates until it attains a
determined height when it overflows and is suddenly and quickly discharged
through the syphon pipe H, whose longer leg H' extends downwards into a
chamber or space H which is connected with the sewer.
The automatic apparatus for setting the syphon in operation when the tank has
become filled with liquid (consisting of the tipping box and bucket) is situated

page_text: within the vessel F to which the water entering the tank does not gain access until
it attains the height of and overflows the lip G. This vessel is connected to the
longer leg H' of the syphon by a curved trap I. the entrance to which is closed by
a valve J. Within this vessel F is pivotted upon trunnions K' a tipping box or
bucket K, into which falls the liquid as it flows over the lip G. This tipping box
or bucket is linked to or falls upon or is otherwise connected with the valve J and
is so constructed that when empty or only partially filled with liquid its centre of
gravity is below its centre of suspension, but when filled above a certain level its
centre of gravity is raised above its centre of suspension and consequently it
overturns into the position indicated by dotted lines and so discharges its contents
into the vessel and by raising the valve to allow them to overflow down the long
leg of the syphon.
The rush of fluid has an exhausting action in the syphon and draws the liquid
that already stands nearly up to the level of the crown of the syphon over the top
and starts the flushing operation.
As soon as the bucket is empty it returns to its normal position (shewn in full
lines) and recloses the valve to prevent air being drawn through the trap into the
syphon.
In our provisional specification we described a flushing apparatus having two
connected tipping boxes acting alternately, but we do not consider that arrangement
so advantageous as the one illustrated herewith.
Having thus described the nature of the said invention and the manner in which
it is to be performed we would have it understood that what we consider to be
novel and original and therefore claim as secured to us under the Letters Patent
herein before first in part recited is ;-
1. In syphon flushing apparatus the use, for setting, the syphon in action, of a
tipping box or bucket discharging through an inlet into the longer leg of the
syphon in combination with a valve for closing the said inlet when the tipping box
is in its normal position substantially as described.
i
2. The improved apparatus for flushing constructed arranged and operating
substantially as described.
In witness whereof I the said John Bailey Denton have hereunto set my
hand and seal this twenty ninth day of September in the year of our
Lord one thousand eight hundred and Eighty two
