Improvements in Flushing Cisterns for Closets and other Purposes.
1, MOSES JAMES ADAMS, Engineer, Sanitary Works, 72, Park Lane, Leeds, 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 follow-
ing statement;
-
In what is termed combination closets it is usual to employ a valve for the
discharge of water to the pan, and difficulty is experienced in obtaining a
sufficiently vigorous flush, hence valves of large diameter are used, and difficulties
are common where they are adopted. The cistern itself may, however, be used
overhead if wished. My improvements broadly consist in the adandonment of
the valve and in use of a tipper in place thereof, and it must be evident that
if a valve gives a tolerable flush, a tipper discharging its contents instantaneously
must be more effective. As will be seen on reference to the accompanying draw-
ing, I provide a casing E which in a measure forms a support for cistern . In-
side casing E a discharge funnel D is fixed in such a way that when the contents
of the revolving tipper G are discharged, the liquid will pass through outlet
horn C to closet flushing nozzle B, and thence to closet A, part of which I have
shewn. The tipper has a wide mouth Z; at rest this mouth is as shewn up-
wards; to discharge the tipper the handle H is turned and the tipper turns upside
down; on releasing the handle it rights itself again being weighted for that
purpose. To the mouth of the tipper is attached a feed mouth S; into this
mouth the feed valve Y discharges so long as float K is down and valve open;
when the tipper has become full it overflows by mouth T, such overflow enters
mouth and so passes to the float chamber W and gradually rising therein lifts
the ball K and shuts off the supply. If the tipper is held upside down then
the water flows to mouth U and shuts off valve so no waste can take effect. If
now the handle H is turned the tipper empties itself to the discharge funnel,
but it should be noted that because the float chamber W is full of water the valve
is shut off and does not feed.
There is a syphon formed by M, M, N and N¹. This syphon is in the float
chamber W and if on the return of the bucket I cause the syphon to set up its
action and empty float chamber W then it is evident the float will fall-the valve
will open and the tipper will again fill. On the tipper there is a projection or
pin R when the bucket is turned over to empty it; this pin comes in contact with
tongue Q and lifts the same together with the lever and syphon dome N. Now
when the tipper returns to its normal position this tongue is allowed to fall and
in falling the dome N also is depressed; this depression of the dome sets the
syphon into work and the contents of the float chamber are withdrawn, the float
falls, the valve opens and the feed again takes place to the tipper, which presently
will fill and overflow, and again the valve will be shut off. By dotted lines I
shew the second position of the lever 0; there are naturally more ways than one
by which I may empty the valve partition and effect other mechanical operations
in this apparatus.

page_text: 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 use of a tipper in a cistern fed by a fresh water supply in combination
with a closet where the same is fixed under 3ft. below cistern so that no flush
pipe as generally used, shall be necessary.
2. The use of a revolving tipper fed by a valve having float and lever-the
said float being operated in a distinct compartment or partition, which com-
partment is filled by overflow from the tipper.
3. The use of a syphon to discharge the contents of the float partition or com-
partment, the said syphon being actuated by the operation of the tipper or by
other equivalent means brought about as the water is discharged from the tipper.
4. The use in a flush tank of a revolving tipper in combination with the over-
flow mouths and float chamber or partition whether used low down as shewn and
described, or whether the same is fixed overhead with a flush pipe.
5. The use and arrangement of the parts and appliances shewn and described
or their equivalent, though differing in conformity substantially the same.
