PROVISIONAL SPECIFICATION.
Improvements in Flushing Apparatus for Closets, Latrines, and
the like.
I, JOHN DUNGEY of 86 New Cross Road, London, in the County of Kent,
Gas Engineer, do hereby declare the nature of this invention to be as follows:
This invention for Improvements in Flushing Apparatus for Closets, Latrines
and the like has for its object to effect the rapid discharge of a large volume of
water so as to thoroughly clear the fecal matter or other deposit from the pan of
the closet or other receptacle and comprises a tipping tank placed in a cistern and
suspended therefrom on two bearing pivots or points which however consist
preferably of the supply or inlet and overflow pipes which pass through the outer
tank, the supply to the tipping tank being controlled by means of a ball or other
suitable cock. The cistern is connected to the closet pan or other receptacle by
means of a pipe in the usual manner, and the tank is tipped by means of a
connecting cord, chain or other suitable connection.

COMPLETE SPECIFICATION.
Improvements in Flushing Apparatus for Closets, Latrines, and
the like.
I JOHN DUNGEY of 86 New Cross Road London in the County of Kent,
Gas 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 :-
This invention for Improvements in Flushing Apparatus for Closets, Latrines
and the like has for its object to effect the rapid discharge of a large volume of
water so as to thoroughly clear the fecal matter or other deposit from the pan of
the closet or other receptacle, and comprises a tipping tank placed in a cistern and
suspended therefrom on two bearing pivots or points, the supply to the tipping tank
being controlled by means of a ball or other suitable supply cock.
In the accompanying sheet of illustrative drawings :-
Fig. 1 represents a side elevation, Fig. 2 an end elevation, and Fig. 3 a plan of a
Hushing apparatus constructed according to this invention.
A tipping tank a is enclosed in a containing cistern b from which it is suspended
by two pivots c, d, the pivot d forming also the nozzle of the overflow pipe. The
pivot points c, d are situated eccentrically with respect to the centre of gravity of
the tank a so that, whether full or empty, it normally occupies a position favourable
for the reception of the flushing water to which position it automatically returns
after displacement, its travel being limited by the stops e, f. The tank a is tipped
by means of a chain g secured to it and passing over a guide pulley h, its end being
secured to a handle i
On tipping the tank a its contents are discharged into the cistern 6 whence it
passes through the contracted outlet / and suitable pipes to the closet pan or other
receptacle in the usual manner.
Secured to the tank a is a sector m concentric with the pivots c, d and which

position the roller q is opposite a notch or indentation r in the sector m which
permits the lever to fall and open the supply valve p. When however the tipping
tank is rotated from its normal position the roller q rides on the periphery of the
sector m and holds the lever o in its elevated position, thereby closing the supply
valve p until the return of the tank to its normal position. The lever o is guided
by means of a forked arm s secured to the supply valve.
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
1. In flushing apparatus for closets, latrines and the like the means for auto-
matically closing the supply valve when the tipping tank is displaced from its
normal position comprising a notched sector or cam m secured to the tipping tank
in combination with a ball lever o with roller q substantially as described.
2. The combination of a sector or cam m secured to the tipping tank valve
lever o with roller and forked guide arm s substantially as described and for the
purpose set forth.
3. A tipping tank a pivoted eccentrically and operated as described in
combination with a containing cistern and contracted outlet / substantially as
described.
4. The general combination of parts constituting my improved flushing apparatus
for closets, latrines and the like, the whole arranged constructed and operating
substantially as described in the foregoing Specification and illustrated in the
drawings hereunto annexed..
