CISTERNS OR FLUSHING APPARATUS FOR WATER CLOSETS & THE LIKE
Year: 1885

page_text: GEORGE CROWE 156 Barrel Well Boughton, Chester, Engineer, and WILLIAM
JAMES, 8 Lightfoot Street Chester, Engineer, do hereby declare the nature of our
invention for CISTERNS OR FLUSHING APPARATUS FOR WATER CLOSETS & THE
LIKE to be as follows:-
We construct these cisterns with a syphon cast or fixed therein also a plate
extending across the cistern and about half the length of the cistern from syphon
end with a space between the plate and bottom of cistern of about two inches, in
this space a sliding piece with a valve therein is moved along by means of a bell
crank lever with fulcrum at top of cistern being worked by ordinary chain and
handle with a balance weight for bringing back the sliding piece and chain.
The operation is as follows: —
The inlet of water to cistern is regulated by an ordinary ball tap which allows
the water to rise in cistern to a little below lower edge of top of syphon and
then shuts off the supply; the space in which the sliding piece works is now filled
with water, the sliding piece being at the outer end: the chain being now pulled
causes the sliding piece to move along pushing the water before it, thus bringing
the syphon into action and causing the contents of cistern down to bottom edge of
short leg of syphon to be discharged, the balance weight bringing back sliding
piece and chain ready for another discharge.
To prevent the continued action whilst the ball tap is admitting water, and also
to regulate the duration of each discharge, we fix near the top of syphon a small
tap the amount of opening of which can be regulated according to the pressure of
water supply.

Cisterns or Flushing Apparatus for Water Closets and the like.
GEORGE CROWE, 156 Barrel Well, Boughton, Chester, Engineer and WILLIAM
JAMES, 8 Lightfoot Street, Chester, Engineer, do hereby declare the nature of our
invention for CISTERNS OR FLUSHING APPARATUS, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
We construct these cisterns A with a syphon B fixed or cast therein, also a
plate C extending across the cistern, and about half the length of cistern from
syphon end, with a space D between the plate, and bottom of cistern of about two
inches, in this space a sliding piece E with a valve F therein is moved along by
means of a bell crank lever G with fulcrum at top of cistern, being worked by
ordinary chain and handle with a balance weight E for bringing back the sliding
piece E to its original position.
1.
The operation is as follows:-The inlet of water to cistern A is regulated by an
ordinary ball tap, which allows the water to rise in cistern to a little below lower
edge of top of syphon, and then shuts off the supply; the space D in which the
sliding piece works is filled with water, the sliding piece E being at the outer end;
the chain being now pulled, causes the sliding piece to move along pushing the
water before it, and bringing the syphon into action, and causing the contents of
cistern down to bottom of short leg of syphon to be discharged, the balance
weight H bringing back sliding piece E, ready for another discharge. When
syphon comes into action the valve F falls into position F' the water passing over
its upper edge.
To prevent the continued action of syphon, whilst the ball tap is admitting
water, and also to regulate the duration of each discharge, we fix near the top of
syphon a small tap the opening of which can be regulated according to the
pressure of water supply.
Having now particularly described and ascertained the nature of our said
invention and what manner the same is to be performed, we declare that
.what we claim is
The sliding piece E and valve F and the arrangement for actuating same,
substantially as shewn on drawings, and described.
