PROVISIONAL SPECIFICATION left by the said Alfred Wheeler at the Office
of the Commissioners of Patents on the 8th February 1879.
ALFRED WHEELER, of the City and County of Oxford. "IMPROVEMENTS IN
APPARATUS FOR SUPPLYING WATER TO WATER CLOSETS, BATHS, LAVATORIES, AND
FOR OTHER FLUSHING PURPOSES."
This Invention relates to the construction of a cistern and apparatus for flushing
water closets, baths, lavatories, and drains, and for preventing waste of water.
The inlet and outlet valves are worked in a simple and efficient manner. without
chains or wires inside the cistern, whereby damage or breakage is avoided.
In carrying out my Invention the flushing cistern is made of iron or other
suitable metal and of the required dimensions, and is formed with a wing or wings
on each side at the back with holes in the wings to allow of the cistern being fixed
by pins and nuts or screws, no other support being required.
To the centre of the front of the cistern at the top (or in any other suitable
position) I fix a bracket or bearing forming a fulcrum in which pivots a cranked
lever, one end of which is slotted so as to extend over the front of the cistern, and
receives the chain (or rod) for operating the valves, as hereinafter described, a stop
on each side of the slot limiting the play of the lever. In or near the centre of
the bottom of this cistern is placed a weighted plug or other suitable outlet valve
opening into the pipe supplying the water closet, bath, or lavatory, and a vertical
air pipe passes through the centre of the outlet valve and is continued to the top
of the cistern, being formed with an eye or link near its upper part, through which
passes the other end of the hereinbefore described cranked lever. The inlet valve
consists of a ball cock of the ordinary construction, the lever or stem of the ball
passing in a slot in the hereinbefore described cranked lever.
By this construction it will be easily understood that if the hereinbefore described

page_text: chain or rod be pulled by its handle the cranked lever will be moved on its fulcrum
and the end thereof which is in the cistern will be raised and will raise the outlet
valve so as to open it and allow the water to pass into the water closet; but the
said lever will, in rising, keep the ball lever raised and the inlet valve closed so as
to shut off the supply of water to the cistern.
When-the-chain-or-rod-is-released the outlet valve will fall back to its seat, and
the-ball-falling-will-open the inlet valve and allow the cistern to be refilled with
water. It will thus-be-seen-that, no matter how long the outlet valve be kept
raised, no more water-than-is-contained in the cistern can be drawn-off at one
operation.

FOR OTHER FLUSHING PURPOSES."
:
This Invention relates to the construction of a cistern and apparatus for flushing
water closets, baths, lavatories, and drains, and for preventing waste of water.
The inlet and outlet valves are worked in a simple and efficient manner without
chains or wires inside the cistern, whereby damage or breakage is avoided.
In carrying out my Invention the flushing cistern is made of iron or other
suitable metal and of the required dimensions, and is formed with a wing or wings
on each side at the back with holes in the wings to allow of the cistern being fixed
by pins and nuts or screws, no other support being required.
To the centre of the front of the cistern at the top (or in any other suitable
position) I fix a bracket or bearing forming a fulcrum, in which pivots a cranked
lever, one end of which is slotted so as to extend over the front of the cistern, and
receives the chain (or rod) for operating the valves, as hereinafter described, a stop
on each side of the slot limiting the play of the lever. In or near the centre of
the bottom of this cistern is placed a weighted plug or other suitable outlet valve
opening into the pipe supplying the water closet, bath, or lavatory, and a vertical
air pipe passes through the centre of the outlet valve and is continued to the top
of the cistern, being formed with an eye or link near its upper part, through which
passes the other end of the hereinbefore described cranked lever. The inlet valve
consists of a ball cock of the ordinary construction, the lever or stem of the ball
passing in a slot in the bereinbefore described cranked lever.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a plan, Figure 2 a
front view, and Figure 3 an end view of my improved apparatus for supplying
water to water closets, baths, lavatories, and for other flushing purposes; Figure 4
is a longitudinal section, and Figure 5 is a transverse section of the same. Similar
letters in all the Figures represent similar parts.
a is the flushing cistern; b, b, the wings for fixing the same; c is the bracket or
bearing forming the fulcrum on which pivots the cranked lever & slotted at d² to
allow it to pass over the front of the cistern; e, the rod or chain attached to the
outer end of the lever d; f is the outlet valve in the bottom of the cistern opening
into the pipe g supplying the water-closet, bath, or lavatory, as the case may be;
is the vertical air pipe passing through the centre of the outlet valve f and
extending to the top of the cistern; i, eye or link in the air pipe h, through which
passes the inner end d¹ of the cranked lever d; j is a ball cock of the ordinary
construction forming the inlet valve, the lever or stem k of the ball passing
through the slot m in the cranked lever d.
By this construction of apparatus it will be easily understood that if the berein-
before described chain or rod e be pulled by its handle n the cranked lever & will
be moved on its fulcrum and the end thereof which is in the cistern will be
raised and will raise the outlet valve f so as to open it and allow the water in the
cistern a to pass into the water closet; but the said lever d will, in rising, keep the
ball lever raised and the inlet valve j closed, so as to shut off the supply of water
to the cistern. When the chain or rod e is released the outlet valve f will fall
back to its seat, and the ball falling will open the inlet valve j and allow the
cistern a to be refilled with water. It will thus be seen that no matter how long
the outlet valve be kept raised no more water than is contained in the cistern can
be drawn off at one operation; o, o', are stops in the slot d to limit the play of
the lever d.

page_text: Having thus described the nature of my said Invention, and the best means
with which I am acquainted for carrying the same into effect, I wish it to be
understood that I do not confine myself to the precise details herein laid down and
shewn in the Drawing, as the same may be varied without' departing from the
peculiar character of my Invention; but what I do claim is,-
Firstly-The-general-arrangement-and-construction-of-the-improved
apparatus
for supplying water to water-closets, baths, lavatories, and for other flushing
purposes, as herein before described; and represented in the accompanying Drawing,
or any mere modification-thereof.
T
Secondly. The peculiar construction of the cranked lever for operating the inlet
and outlet valves, as hereinbefore described, and represented in the accompanying
Drawing.
In witness whereof, I, the said Alfred Wheeler, have hereto set my hand and
seal, this Seventh day of August, in the year of our Lord One--thousand
eight hundred and seventy nine.
