Flushing Purposes.
.
1, EDWARD GEORGE HIGHTON. of. The Eagle Foundry, 20 Graham Street
City Road in the City of London Manufacturer; do hereby declare the nature
of the said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings and to the figures and letters marked
thereon:-
This invention has for its object improvements in syphon-water waste preventers
for flushing purposes whereby a much more rapid syphon action is set up than
heretofore.
I will proceed aided by the accompanying drawings fully to describe my
invention.
Figure 1. is a plan and Figure 2 is a sectional view of a syphon water waste
preventer constructed according to my invention.
Figure 3. is a section on the line & z.
Figure 4. is a plan and Figure 5. is a side elevation of the metal ring or plunger
and standards.
In all the figures like parts are indicated by similar letters of reference.
According to this invention I provide an ordinary flushing cistern, a, with a
well a' formed in one therewith and I secure centrally in such well a vertical stand
pipe, b, built up and formed of an inner cylindrical chamber or down pipe c, and
an outer cylindrical chamber or cover, d; these two chambers are firmly secured
together.
The inner chamber or down pipe, c, has formed in its upper end two, or more,
openings, c', its lower or outlet end being secured by suitable means to the well, a',
of the cistern, a; the lower or outlet end has a number of webs or distance pieces c³
secured thereto for the purpose hereinafter described.
The outer chamber or cover, d, passes over the inner chamber c and has a
number of slots or openings, d, formed in its lower end which is strengthened by
means of the webs above mentioned these webs c* also keep the two chambers
the required distance apart. The upper end of the outer chamber or cover d is
closed.
Fitting the well a' loosely is a heavy metal ring or plunger e which passes freely
over the stand pipe 6 and is provided with arms f, f', carrying the trunnions f³, f
which rest or are secured loosely in hooks or bearings g, formed in the forked end
of the lever h.
The operation of my invention is as follows:-The cistern a being filled with
water by means of an ordinary ball cock (not shown) the lever is pulled down
and raises or lifts the heavy metal ring e a certain distance in which position no
water will escape from the cistern but immediately the lever is released and the
metal ring e falls the water is forced through the openings d' in the outer chamber
or cover d and up between the two chambers and through the openings c¹ in the
upper part of the inner chamber or down pipe c and thence through the outlet at
its lower end (as shown by the arrows) with sufficient force to set up a rapid syphon
action which continues until the cistern is empty.

page_text: Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The peculiar construction of a stand pipe for flushing cisterns consisting of
an inner cylindrical chamber and an outer cylindrical chamber or cover secured
together and fixed in the well of the cistern substantially as herein described and
shown in the accompanying drawings.
2. The construction of a stand pipe for flushing cisterns consisting of an inner
cylindrical chamber having a number of openings in its upper end, and an outer
cylindrical chamber having a number of slots or openings at its lower end, such
chambers being firmly secured together substantially as herein described and shown
in the accompanying drawings and for the purpose stated.
3. The heavy metal ring or plunger provided with arms or standards carrying
trunnions which loosely fit in bearings in the pull up lever substantially as herein
described and shown and for the purpose stated.
Dated this 16th day of July 1894.
