We, JOSEPH WALL, of Liverpool, in the County of Lancaster, Plumber;
and THOMAS DODD, also of Liverpool, aforesaid, Glass Merchant, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE CON-
STRUCTION AND ARRANGEMENT OF APPARATUS FOR REGULATING THE FLOW OR
PASSAGE OF FLUIDS," to be as follows:-
The objects of our Invention are, firstly, to economize the fluids for flushing
waterclosets, and, secondly, to secure perfect regulation and flushing by a
simplification of apparatus for that purpose, part of which is applicable for
controlling the flow of fluids otherwise used.
Under that part of the title of our Invention where we mention "con-
struction of apparatus," we refer to a new device of an equilibrium three-way
tap or apparatus, so planned that by movement of the spindle a supply of fluid
is permitted to flow through in one direction, and, by movement the contrary
way the supply is closed, and the same fluid returned through the same tap
or apparatus, and finally passed off or discharged by a third way. This tap
or apparatus, which is suitable for use in many positions, and for other
purposes than flushing waterclosets, has a rigid spindle, on which is a button
or other valve fitted to close against suitable seatings, and will be better

page_text: understood in the following description of its application or use as part of the
arrangement of apparatus," also mentioned in the title.
We have already stated that one of our objects is to economize flushing
fluids, we therefore adopt the system with pressure cistern and pressure seat,
both of which are well known. The tap or apparatus above referred to is
fitted to the supply pipe from the street mains in large towns from a cistern
at an elevation, or from any other source. It is also secured to a second pipe
for carrying the flushing fluid to the pressure cistern (which is fitted in the
ordinary position), and from the said pressure cistern back again to the tap,
and also to a third pipe for carrying the said flushing fluids from the said tap
or apparatus to the pan; thus the tap or apparatus is so placed that the
depression of the moveable seat acts on the spindle, closes the passage to
the pan, opens the supply valve or passage to the cistern, and permits the
flushing fluid to pass into the pressure cistern, which, of course, will contain
more or less fluid according to the height of the supply column. When the
seat is allowed to rise to its normal position the supply valve is closed by
the movement, and communication is only open between the pressure cistern
and watercloset pan, into which latter, by way of the second and third pipe
connections herein-before mentioned, the flushing fluid will be discharged with
force by the pressure of the compressed air contained in the said cistern. As
all the parts act simply by the weight of the person using the closet, and as
the quantity of flushing fluid contained in the pressure cistern is all that can
be used at one time or by one movement, waste is prevented.
