ISAAC SHONE, of Wrexham, in the County of Denbigh, Civil and Mining
Engineer. "IMPROVEMENTS IN AND RELATING TO TANKS, CISTERNS, OR GULLEYS
FOR FLUSHING PURPOSES."
My Invention has for its object certain improvements in and relating to that
class of tanks, cisterns, or gulleys, in which the syphon system of emptying is
adopted, such tanks, cisterns, or gulleys being self acting and automatically
emptying as soon as a given level has been reached by the contents of the tank,
cistern, or gulley.
My Invention consists,―
Firstly. In the novelty of shape or form which I adopt in constructing the tanks,
cisterns, or gulleya.
Secondly. In the trapping of such tanks, cisterns, or gulleys.
Thirdly. In the method of charging or filling such tanks, cisterns, or gulleys, so
that the syphon is certain of correct action the instant or immediately after such
tank, cistern, or gulley shall have become charged.
First. The shape or form of the tank, cistern, or gulley is preferably cylindrical,
the upper part being of reduced diameter to the body of the vessel, and the bottom
being spherical or rounded, developing into a discharge outlet and syphon pipe,
which syphon pipe is brought up in a bend outside of the tank, cistern, or gulley, and
the long leg carried down below the tank, cistern, or gulley, where it joins an elbow
trap, and thence to the sewer, drain, or other outlet. By so forming or shaping the
tank, cistern, or gulley I am enabled to insure a perfect scour of its contents when
emptying.
Second. The trapping is effected, first, by the elbow band joining the receptacle
to the syphon pipe; and secondly, by the elbow bend joining the syphon pipe to

page_text: the outlet. The tank, cistern, or gulley may be further trapped by the inlet or
feed pipe descending into the tank, cistern, or gulley, and is also ventilated by a
suitable pipe provided at the top of the tank, cistern, or gulley.
Third. In tanks, cisterns, or gulleys heretoforo constructed to work or flush by
means of a syphon pipo, it has been found very often the case that when the tank,
cistern, or gulley fills slowly and evenly without agitation the contents are apt to
dribble over the bend connecting the long leg with the short leg of the syphon, and
thus the flushing properties of the tank, cistern, or gulley were rendered nil. To
obviate this the elbow bend connecting the legs of the syphon has been contracted
and also arranged to come over the top of the tank; also the long leg of the
syphon has been inserted into a trap, and various other methods have been tried
without effect. This difficulty is overcome in my Invention by contracting the
upper part of the tank, cistern, or gulley, and by the method which I adopt to
charge and fill the tank, cistern, or gulley, which method consists in the use and
application for this particular purpose of a tipping basin or vessel arranged over
the inlet or supply pipe of the tank, cistern, or gulley in such a manner that the
tank, cistern, or gulley is filled intermittently by the tipping of this basin or vessel
which is made of capacity to fill the upper part of the tank, cistern, or gulley in
excess of the capacity of the elbow bend of the syphon pipe. By so filling the
tank, cistern, or gulley through the medium of this tipping vessel I ensure the
perfect action of the syphon pipe, as when the tank, cistern, or gulley is charged
the next tip of the feeding vessel ensures the filling of the syphon pipe, and thereby
its correct action.
When my Invention is used as a street gulloy or like receptacle where it is
necessary to intercept foreign matter from entering the drain proper, I build or erect
the gulley in a suitable well under a manhole, and in proximity to a receiver
provided with a suitable inlet grid and fed by tributary pipes if necessary. The
gulley is supplied through its tipping basin and supply pipe or orifice from a
discharge pipe or overflow pipe in connection with the adjacent receiver. In tho
receiver will be deposited all soils, gravel, and foreign matter, which can be
removed through the grid hole, the liquid only finding its way into the flushing
gulley.
The tank, cistern, or gulley may be fed or filled through a feed or supply pipe
opening into the contracted upper part of the vessel, and provided with a tipping
basin as before mentioned, or the tank, cistern, or gulley may receive its main feed
or supply through an independent pipe opening into any suitable part of the vessel,
and the supply pipe with the tipping basin in connection with the upper part
of the vessel may be only used as an auxiliary to facilitate the working of the
phon.

page_text: The tank A may be made with its upper part A¹ contracted and of a reduced
diameter to the body of the vessel, as shown at Figure 14. The pipe B may also be
formed as shown at Figure 14. The soil pipe J and the scullery pipe K may fill
the tank A through the tipping vessel L only, as shown at Figure 14, or the soil
pipe J may discharge into the tank A, and the scullery pipe K into the vessel L, as
shown at Figure 1.
When the Invention is applied to a street gulley or like receptacle where it is
necessary to intercept and prevent foreign matter from entering the drain pipe
proper I build or erect the gulley A, as shown at Figure 4, in a suitable well X
under a manhole N. Q is a receiver with an inlet grid P; R is a tributary drain.
The gulley A is supplied through the tipping basin L which receives the liquid from
the overflow pipe K in connection with the receiver Q. In the receiver will be
deposited all soils, gravel, and foreign matter which can be removed by lifting the
grid P, the liquid only finding its way into the flushing galley.
An apparatus constructed according to my Invention can be used with great
advantage for flushing sewers or drains at their heads or sources. The apparatus
may be supplied with liquid by a branch from the sewer itself, or with water from a
main or otherwise, which water may be slowly running into the flush tank by means
of the tipping base, which tank when full will flush the sewer or drain. The flow
of water may be so arranged as to flush the sewer or drain a given number of
times during the day or other period of time. Thus a constant automatic flushing
of the sewer or drain is obtained which can be applied to any gravitating or other
system of sewerage.
Having now fully described and ascertained the nature of my Invention, and the
system, mode, or manner in or under which the same is or may be used or practically
carried into effect, what I claim as my Invention and secured to me by the herein-
before in part recited Letters Patent is,—
Firstly. A flushing tank, cistern, or gulley such as A provided with an outside
syphon pipe such as C, and a tipping charging vessel such as L, as herein described,
and as illustrated at Figures 1, 14, 2, and 3 of the accompanying Drawings.
Secondly. A flushing gulley such as A provided with a syphon such as C, and a
tipping vessel such as L, and a receiver or interceptor such as Q, as herein
described, and as illustrated at Figure 4 of the accompanying Drawings.
Thirdly. The improved system of flushing sewers or drains, as herein before
described, by the use of a receptacle constructed and operating as described, and
such as illustrated in the accompanying Drawings.
In witness whereof, I, the said Isaac Shone, have hereunto set my hand and
seal, this Twenty-second day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
