Plumber do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus for drawing off water. It is so arranged that
at each movement of a handle or lever water is delivered and the quantity passing
between one movement and another in no case exceeds a certain prearranged
measure.
The apparatus comprises a cistern of the required capacity usually small, supplied
from any source by means of a ball valve or the like and a delivery pipe the mouth
of which stands above the water level in the cistern when full. The delivery pipe
is covered by a bell or hood of peculiar form, such that a rectangular flap or dasher
can move freely within it upwards about an horizontal axis whilst but little water
is able to pass from one side of the flap or dasher to the other.
The flap or dasher is rectangular in form long and narrow it has a socket at one
end and a pin serving as the axis passes through this socket and also through the
sides of the cistern. The pin or axis-is horizontal and situate within the cistern at
the base of the delivery pipe. The end of the socket extends beyond the side of
the bell or hood and it carries a lever.
•
This lever is operated in any convenient manner as for example by connection
with a wire and bell crank. The dasher is thus caused to move around the pin or
axis and it then carries the water before it up the bell or hood and into the
delivery pipe.
In this way a syphon like action is started and the water is drawn into the
bell or hood; it then continues to descend the delivery pipe until the cistern is
empty.
In order that the flap or dasher may return more freely to its place whenever
the handle is released I prefer to provide it with a valve upon its face which opens
and allows the water to pass during the return movement.

page_text: with the lever K. This lover has its fulcrum at K' upon the movable cover A¹ of
the cistern A. There is a hole in the cover by which the top of the hood E passes
out and the cover may aid in supporting the hood. There is also a hole in the
cover A¹ for the passage of the connecting rod L. M is a chain or cord or other
connection to the other end of the lever K.
The action of the apparatus is as follows:-
When at rest the weight of the dasher or flap G maintains it in the position
indicated by dotted lines at G* and the cistern A fills with water from the supply
pipe B through the valve C. The float shuts off the incoming water when the
cistern is full. Then when it is required that the contents of the cistern should be
delivered through the pipe D, the chain M is pulled either by hand or any con-
venient connection. So the dasher or flap G is rapidly raised into the position
indicated by the full lines in the drawing and the flap as it rises drives the water
before it into the portion of the hood enclosing the upper end of the pipe D. The
water so raised rapidly descends the pipe D driving the air before it, and the con-
sequence is that a siphon like action is established; the hood becomes full of water
and the water ascending from the cistern passes the flap G now in its highest
position and descends the pipe D. The siphon constituted by the hood E and the
delivery pipe D remains full of water until the cistern A. has been emptied; then
the flap & falls back to its original position and the cistern A, re-fills.
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. The combination substantially as described in a flushing cistern or water
waste preventer, of the delivery pipe D, hood E, flap or dasher G and axis H.
2. My improved flushing cistern or water waste preventer substantially as
described and represented by the annexed drawings.
