PROVISIONAL SPECIFICATION.
A New or Improved Flushing Cistern or Waste Water Preventer.
ALFRED CLIFFORD, Claremont House Hawley Road near Dartford Kent,
Plumber and Sanitary Engineer do hereby declare the nature of this invention
to be as follows:-
As shewn on drawings in section Fig. 1. the arrangement consists of a tank
containing a syphon made of cast iron or other suitable metal.
Within this syphon is fitted a metal valve A Fig. 3 of any suitable form.
This valve is attached to a chain B. or any other suitable contrivance
answering the same purpose, which runs round on the brass or other suitable metal
wheels, when the cistern is filled with water and the handle is pulled it lifts the
valve up in the syphon thereby forcing the water over top and discharging all
the water from it (the cistern) and the valve falls again to the bottom on handle
being released. The small disc C. at top of valve slides up and down on the
pin D with the action of the water as it passes up the syphon.
A small groove is made for the chain to work inside the syphon so that the
valve cannot come in contact with it. The wheels and valve inside syphon are
detachable and can be taken out when required by withdrawing two screws at
bottom of syphon. The syphon and chain can also be used right or left hand.
The advantage of this cistern is that it starts on the least pull of the chain and
cannot possibly get out of order there being no perishable parts and it is noiseless
in action there being no cranks or levers, a small air pipe can be inserted in any
suitable part of the syphon.

CUMI LEIDDI MUIFICATION.
A New or Improved Flushing Cistern or Waste Water Preventer.
ALFRED CLIFFORD Claremont House Hawley Road near Dartford Kent
Plumber and Sanitary 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 :-
To more explicitly describe my invention this Specification is accompanied by
2 sheets of drawings having letters of reference thereon.
Fig. 1. Sheet 1. shews the section of a cistern containing a syphon made of
cast iron or other suitable metal. Within this syphon is fitted a metal valve A
Figures 2. 3 and 4 of any suitable form but by preference as shown. The valve
is attached to a chain B or any other suitable contrivance answering the same
purpose which passes over and under brass or other pully wheels C as shewn on
Figures 1 and 2 terminating with a handle or ring for pulling purposes.
The chain is prevented from slipping off the pully wheels by a slight metal
band passing round front of wheel from the axle flanges.
When the cistern is filled with water and the handle is pulled it lifts the valve
up in the syphon thereby forcing the water up and discharging it from cistern and

page_text: the handle being released from the hand, the valve falls automatically back to its
place. The two lids at top of valve are loosely hinged and open or close with the
flow of water.
The main pully wheel C¹ which is directly over the valve is attached to a
upright and bracket D carrying the axle and a flanged- stop at top, to regulate the
height valve can be raised to.
This metal upright and bracket D is so shaped in section as to neatly fit a dove-
tailed groove E in which it slides from bottom, in syphon.
The grove F at back of dovetail is for chain to work in. The wheels and valve
inside syphon are easily detachable and can be taken out when required by
removing small screws or pins.
The advantage of this arrangement is that it starts on the slightest pull of the
chain and cannot possibly get out of order there being no perishable parts and is
noiseless in action there being no cranks or levers.
A small air pipe can be inserted in any suitable part of the syphon if thought
necessary.
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
The syphon arrangement in its entirety including the shape thereof the valve
with the hinged lids, the arrangement of pully wheels and chain, the method of
fixing the main pully wheel, the adjustability of the different parts and the
combination of the whole and I do not confine myself to the nature of material
used in the construction of the same the shape or size of cistern which can be
made to flush in any quantity.
