We, CHARLES HENRY WOODHOUSE and THOMAS WILFRED WOODHOUSE, both of
Hexthorpe Iron and Brass Works, Doncaster, in the County of York, Manu-
facturers, and DENNIS WILLIAM COok, Engineer, of the same address, do hereby
declare the nature of our invention to be as follows:-
Our invention relates to improvements in the construction of syphon flushing
cisterns, such as are used for water closets and like places, and has for its object
to reduce the cost of fitting, by simplifying the mechanism, and thus rendering
it more durable.
We use an ordinary form of cistern prepared with a circular well, over the top
edge of which project two fixed lugs, and from the centre of which rises the
flushing pipe over which the dome or bell is placed.
The lower edge of the dome is enlarged to fit freely within the well, and
grooves are cut in the edge to enable it to be passed over the lugs before men-
tioned; when it has passed the said lugs it is turned round a quarter turn, to
bring the side pins which engage with the pull lever into position, and also to
prevent the dome being accidentally lifted out of the well.
In the edge of the dome and equidistant between the grooves before mentioned
are placed rubber stops or buffers which serve the double purpose of keeping an
open water way under the edge of the dome, and preventing the metal dome
striking the lugs when it is raised, or the bottom of the well when it is lowered.
We prefer to secure the blocks of rubber by making a keyhole shaped slot in
the edge of the dome into which the middle part of the rubber may be passed
by stretching it so as to reduce its size, and passing it through the narrow part
while it is in that condition, leaving a portion to project both above and below
the edge of the dome.
:
The grooves for passing over the lugs form water ways past the dome into
the well and the interior of the dome; we may if found desirable attach a simple.
form of valve to these inlets, to allow water to pass within, but not out.
We make the forked end of the pull lever with an eye in one side; and a hook
on the other, to enable it to be readily attached to and released from the dome,
while its axis simply rests in two hollows formed in the edge of the cistern.

page_text: facturers, and DENNIS WILLIAM Cook, Engineer, of the same address, 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:-
Our invention relates to improvements in the construction of syphon flushing
cisterns, such as are used for water closets and like places, and has for its object
to reduce the cost of fitting by simplifying the construction and mechanism,
and thereby rendering it more durable.
A cistern made according to our invention is illustrated in the annexed sheet
of drawings; like letters refer to like parts in both figures.
Fig. 1, represents a cistern in section.
Fig. 2, plan of cistern, the supply ball tap being omitted in both views.
In carrying our invention into practice as shown, we use an ordinary form
of cistern A, prepared with a circular well B, having two fixed lugs C, projecting
over its top edge, and from the centre of the well rises the flushing pipe D,
covered by the dome or charging bell E.
The lower part of the dome is flared or made trumpet mouthed as shown,
and its perimeter fits loosely within the circumference of the well B; it is
provided with slots or recesses F, to enable it to be passed over the lugs C, before
mentioned, and equidistant between the said slots F, we fix rubber stops or
buffers G, which serve the double purpose of raising the dome from the bottom
of the well and thus keeping an open water way to the interior, and acting
as buffers also between the dome and the fixed lugs C, when the dome is raised
by the action of the lever H, and between the dome and the bosses J, on the
bottom of the well.
To secure these blocks of rubber to the edge of the dome in a simple, inexpen-
sive and effectual manner we prepare slots through the edge, of a keyhole form,
into which a short piece of solid rubber may be passed by stretching it longi-
tudinally until its centre part can be passed through the narrow opening, of
the slot into the enlarged portion, leaving the ends to project above and below
as shown in Fig. 1.
The dome E, after passing the lugs C, is given a quarter turn, and the grooves
or slots F, then form water ways through the flange to the interior of the dome,
and if found desirable they may have flap valves attached which will permit
water to enter but not to return.
"
The forked lever H, is made with an eye on one side and an open slot on the
other, to enable it to be readily attached to and released from the dome, its
axis I, simply resting in semicircular hollows in the edges of the cistern.
Having now particularly described and ascertained the nature of our said.
invention, and in what manner the same is to be performed we declare that
what we claim is:-
1 In a syphon flushing cistern, having a circular well B; the overhanging
lugs C, the dome E, provided with open slots F, and rubber buffers G, all in
combination, as hereinbefore described and shown.
2-A syphon flushing cistern having all the parts hereinbefore described and
shown, in combination.
