Improvements in Syphon Flushing Cisterns.
We, JAMES RICHARD DAVIES, of 1 Holly Walk, Luton, Bedfordshire, Brass-
founder, and ROBERT SAMUEL LLOYD, of Lemsford Road, St. Albans,
Hertfordshire, Engineer, do hereby declare the nature of this invention to be as
follows:-
The outlet leg of the syphon pipe is fixed in the bottom of the cistern and
connected to the water closet or other apparatus to be flushed. The lower end of
the other leg of the syphon passes into a well of the cistern bottom, and is there
bent upward terminating with a bellmouth in a thin saucer like disc, over which
fits loosely a cap that is connected to a pull lever the parts being so weighted or
arranged that when the cap is raised and the pull is let go the cap shall descend
quickly whereby the water enclosed in the space between the disc and the cap is
forced down into the lower bend of the syphon, then up into the ascending leg of
same and then over and down into the outlet leg thus starting the syphon action,
and emptying the cistern and most of the well, the following water entering the
aforesaid space either by one or more suitably arranged holes in the cap and by
the clearance space between the disc and the loosely fitting cap, or by the said
clearance space only or by a cone shaped opening in the syphon pipe, or by both.
Or the cap and lever gear connected to the pull may be so weighted or arranged
that the cap is depressed by the pull action. The disc and cap may be of a
square form with rounded corners and the corners of the cap and the cone shaped
opening in the syphon pipe may offer sufficient clearance for the entry of the water
into the syphon.

Improvements in Syphon Flushing Cisterns.
We, JAMES RICHARD DAVIES of 1 Holly Walk, Luton Bedfordshire Brass-
founder and ROBERT SAMUEL LLOYD of Lemsford Road St. Albans,
Hertfordshire, Engineer 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:-
This invention consists in improvements in the construction of syphon flushing
cisterns comprising simplicity efficiency and cheapness.
Fig. 1 of the accompanying drawings is a part sectional elevation and Fig. 2 a
plan of a syphon flushing cistern constructed according to this invention.
The outlet leg A of the syphon pipe is fixed in the bottom of the cistern B and is
connected to the water closet or other apparatus to be flushed. The lower end of
the other leg A¹ passes into a well or recess B¹ of the cistern bottom and is there

page_text: bent upward terminating with a bellmouth in a thin saucer like disc A over the
edge of which fits loosely a cap C that by a stem C¹ or it might be a jointed rod
or a chain) is connected to the lever D which is fixed on a spindle E that has its
bearing brackets B' cast on the top of the cistern the spindle E having the pull
lever fixed on its end outside the cistern. F is the cistern cover. By the one
sided arrangement of the stem C¹ we save space taken up by the levers D and D'.
The syphon is by preference of an oval or flattened section which improves the
action as is well known. The parts are so weighted or arranged that when the
cap C is raised and the pull is let go, the cap shall descend quickly whereby
the water enclosed in the space between the disc A2 and the cap C is forced down
into the lower bend of the syphon, then up into the ascending leg A¹ and then
over and down into the outlet leg A, thus starting the syphon action and emptying
the cistern and part of the well, the following water entering the aforesaid space
either by one or more suitably arranged holes in the cap and by the clearance space
between the disc A' and the loosely fitting cap C or by the said clearance space
only and partly also by an opening or clearance space C' in the cap where the
syphon leg A passes through.
The cap and lever gear connected to the pull may if desired be so weighted or
arranged that the cap is depressed by the pull action.
The disc and cap are by preference of the square form shown with rounded
corners.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
The improved construction of syphon cistern in which the syphon outlet leg A
is fixed to the bottom of the cistern B and the inlet leg A terminates in an
enlargement or saucerlike disc in a well B' of the cistern over which disc fits
loosely a cap C that is connected to the pull lever substantially as described and
shown.
