Improvements in Syphonic Flushing Apparatus.
We, THOMAS GARFORTH RHODES, of Albert Terrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of Airedale Mount, Rodley, near Leeds, Engineer, both in
the County of York, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct syphonic flushing apparatus in
such a manner that the syphonic action may be more readily and efficiently
started than heretofore, the contents of a cistern being then discharged through
the full bore of the discharge pipe of the cistern, and this without the use of
pistons or other water propelling mechanical parts.
In carrying our invention into effect, we employ a cup framework having an
outlet at its base passing through the bottom of the cistern, and in the centre
of the cup an auxiliary cup is provided having an orifice in its centre and being
supported in position by means of wings or distance pieces in the interior of the.
main cup. The long arm of the syphon bend is screwed or otherwise fitted into
the orifice before referred to and the lips of the main and auxiliary cups leaving
an annular space between them, are closed by means of a ring valve carrying an
annular washer on its under side. The ring valve is operated by means of a
lever and connecting links, and its path of movement is guided by the long arm
of the syphon on which it slides. The lifting of the ring valve thus admits
water to the annular space between the main and auxiliary cups and a flush is
thus admitted entirely around the syphon leg. The contents of the discharge
arm of the syphon are thus subject to an effective and uniform flush, with the
consequent result that a discharge is effected through the full bore of the syphon.
By forming the valve in two parts with a suction connection between them, the
lower part of the valve may be caused to fall down and automatically close the
annular entrance, in the event of the handle being kept down after the discharge
of the contents of the cistern.

We, THOMAS GARFORTH RHODES, of Albert, Terrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of Airedale Mount, Rodley, near Leeds, Engineer, both in
5 the County of York, do hereby declare the nature of this invention, and in what
D...0il

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
This invention relates to the construction of syphonic flushing apparatus in
which the long and short arms of the syphon are rigidly fixed in position; and
the object of our invention is to construct and provide means whereby an
annular stream of water may be admitted to the long arm of the syphon in
order to readily and efficiently start the syphonic action, which will continue
until the contents of the cistern are discharged.
In order that our invention may be readily understood, reference will be made
to the accompanying drawings, in which Figure 1 illustrates in sectional eleva-
tion apparatus constructed in accordance therewith. Figure 2 is a cross sectional
plan view taken on the line X Y of Figure 1, with the valve removed; and
Figure 3 is a perspective view illustrating the general arrangement of the
apparatus.
In carrying our invention into effect, and referring particularly to Figures 1
and 2 of the drawing, we employ a cup framework A having an outlet B at its
base passing through the bottom of the cistern C, and in the centre of the cup A
an auxiliary cup D is provided having an orifice in its centre and being sup-
ported in position by means of wings or distance pieces in the interior of the
cup A. The long arm F of the syphon bend is screwed or otherwise fitted into
the central orifice of the cup D), and the lips of the cups A and D leaving an
annular space G between them are closed by means of a ring valve H carrying
an annular washer J on its under side. As shown at Figure 1, the edge of the
lip is preferably arranged above the level of the edge of the lip A, and the
base of the valve H, immediately over the lip D,
formed with an annular
recess as indicated in the drawing. The ring valve H is operated by means of
a lever K and connecting links L L, and its path of movement is guided by
the long arm F of the syphon on which it slides.
Upon lifting the ring valve H, .water is free to pass to the annular space G
between the cups A and D), and an annular stream is thus admitted into the
long arm of the syphon, thereby starting the syphonic action, which will continue
through the full bore of the discharge pipe until the contents of the cistern are
discharged.
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 syphonic flushing apparatus, the employment of cups A and D, located
at the base of the cistern C, constituting a valve seating and an annular passage
way G, in combination with the long arm F', outlet B and valve H, substantially
as and for the purposes described. .
2. The general construction, combination and arrangement of the parts con-
stituting our invention substantially as herein described and illustrated with
reference to the accompanying drawing.
