Improvements relating to Flushing Cisterns.
We, CHARLES HENRY WOODHOUSE, and THOMAS WILFRED WOODHOUSE,
Manufacturers, and DENNIS WILLIAM COOK, Engineer, all of Hexthorpe Brass &
Iron Works, Doncaster, in the County of York, do hereby declare the nature of
this invention and in what manner the same has to be performed, to be particularly
described and ascertained in and by the following statement:—
Our invention refers more particularly to the details of construction of syphon-
flushing cisterns, and not to the principle of operation, and a cistern constructed
according to our invention is illustrated in the annexed sheet of drawings, referring
to which
Fig. 1, represents an elevation of a flushing cistern, part of the side being
removed to exhibit the interior, portions of which are in section.
Fig. 2, is a plan of same with the upper portions removed to show the lower
parts.
Fig. 3, represents the base of the cylinder.
In carrying out our invention we construct a cistern 1, of ordinary form, pro-
vided with a well 2, so arranged in position, that room is provided upon the base
of the cistern to enable it to be supported by brackets at the parts marked 3.
The well 2, is provided on or in each opposite side with vertical slots 4, to
receive and support a valve 5, the edges of which are made to slide into such
slots, and thus while it is securely held in position, and the joint easily made, it
can be readily removed when desirable.
In Fig. 1, the valve is shown partly open but in its normal position it is closed,
to which it returns automatically by gravity.
The valve plate is detachable so that its face and its seating which are both
flat can be readily faced by simple and inexpensive means.
The cylinder 6, of cast iron, sheet copper or the like, copper being preferred,
is placed over the centre of the well or thereabouts, and preferably but not of
necessity it is internally flanged on three sides see Fig. 3. The two side flanges
rest upon the floor of the cistern and are fastened thereto, and the one marked 7,
rests upon the correspondingly shaped top plate of the valve 5, the part without
a flange fitting against a rim 8, upon the socket piece 9, thus enabling a water-
tight joint to be easily made.
The charging plunger 10, which we prefer to make from sheet copper of the
form shown, is carried by the rod 11, and is operated by the weighted pull-down
lever 12.
.
:
The syphon pipe 13, is attached to the socket piece 9, as shown, or it may be
made by casting it in one piece with the socket, the flange of which is secured to
the floor of the cistern by suitable means. By constructing the several parts as
described and shown, we are enabled to remove the charging cylinder 6, and the
valve 5, without disturbing the syphon 13, or socket piece 9.
We are aware that flushing cisterns have been made having a somewhat similar
arrangement of the working parts, and we therefore wish it to be understood that
we do not make any claim to the use of charging cylinders with plungers in
combination with valves and syphons in a broad sense, but:

page_text: 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 provided with a well 2, the combination of a
charging cylinder 6, having an internal plunger 10, in combination with a valve 5,
and a syphon socket piece 9, all constructed and arranged as hereinbefore described
and shown.
2 In a syphon flushing cistern provided with a well 2, the combination with a
charging cylinder 6, of a socket piece 9, to engage with the end of the syphon
pipe or be made in one piece with it, and having a segmental joint flange 8, to
fit against the cylinder as herein before described and shown.
3In a syphon flushing cistern provided with a well, and with a charging
cylinder, an inlet valve 5, having a balanced swing door, and fitting into vertical
slots in the sides of the well, to enable it to be readily fixed or removed, as herein
before described and shown.
4-A syphon flushing cistern having all its chief parts constructed and arranged
as herein before described and shown in the annexed drawings.
Dated the on day of August 1990.
