Certain Improvements in Syphon Flushing Apparatus.
I, JAMES WILLIAM MADELEY, of Albany Works, Lombard Street, in the City
of Birmingham, Brassfounder and Sanitary Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to syphon flushing apparatus of that kind in
which the short leg of the syphon is formed as a vertical cylinder, containing a
piston past which the water can flow, the said piston being connected to a piston
rod which passes up through a slide or stuffing box in the upper part of the
syphon and is operated by a lever and pull chain, so that when the tank and
syphon are charged and the piston is raised suddenly, the water in the cylinder
will thereby we raised and caused to overflow into the long leg of the syphon and
thus set the syphon in action and syphon the water out of the cistern.
My invention consists of the hereindescribed improved means for guiding and
connecting the piston rod to the said operating lever so as to ensure the piston
rod and piston always working up and down vertically to prevent any side wear
in the piston guide which is a defect in syphon flushing cisterns of this class as
at present constructed the sideways movement of the piston rod sometimes causing
the piston to stick in the top of the cylinder instead of gravitating to the bottom
of the same after the cistern has been discharged..
In carrying out my invention the top part of the syphon above the cylinder is
made with a bracket forming a guide for the upper part of the piston rod in
addition to the said guide in the top of the cylinder. The piston rod is connected
to the operating lever by means of two side links the ends of which are respectively
jointed to the forked end of the operating lever and to a cross head or cross pin
which is formed on or fixed to the piston rod either between the two guides or
above the same. By this arrangement of parts the piston rod is effectually
guided and is not liable to wear the guides sideways as by employing the side
links the operating lever does not cause any side strain to the piston rod.
In a modification of my invention instead of employing the side links as stated
above, I make the forked end of the operating lever with holes to engage
directly with the cross head or cross pin of the piston rod, the said holes in the
forked end of the operating lever being slotted slightly to allow of the free move-
ment of the cross head
In another arrangement of my invention the said cross head is made slotted
and the forked end of the operating lever is arranged to fit in the slotted parts of
the cross head or block, the said forked ends of the lever being by preference
fitted with rollers to diminish friction.

I, JAMES WILLIAM MADELEY, of Albany Works, Lombard Street, in the City
of Birmingham, Brassfounder and Sanitary 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 has reference to syphon flushing apparatus of that kind in
which the short leg of the syphon is formed as a vertical cylinder containing a
piston past which the water can flow, the said piston being connected to a piston
rod which passes up through a slide or stuffing box in the upper part of the
syphon and is operated by a lever and pull chain, so that when the tank and
syphon are charged and the piston is raised suddenly, the water in the cylinder
will thereby be raised and caused to overflow into the long leg of the syphon and
thus set the syphon in action and syphon the water out of the cistern.
My invention consists of the hereindescribed improved means for guiding and
connecting the piston rod to the said operating lever so as to ensure the piston
rod and piston always working up and down vertically to prevent any side wear
in the piston guide which is a defect in syphon flushing cisterns of this class as
at present constructed the sideways movement of the piston rod sometimes causing
the piston to stick in the top of the cylinder instead of gravitating to the bottom
of the same after the cistern has been discharged.
I will describe my invention by referring to the accompanying drawings en
which Figs. 1 and 2 are sectional elevations of a syphon flushing apparatus
embodying my invention; Fig. 3 is a plan of the same and Fig. 4 shews a part
of the same separately; Fig. 5 illustrates a modified form of the operating lever:
and Figs. 6, 7, 8 and 9 illustrate a further modification of my invention.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
A is the flushing tank; B is the short leg of the syphon forming the vertical
cylinder and containing the piston C past which the water can flow; D is the
piston rod; E is the operating lever turning on the fulcrum e¹ and provided with
the pull chain e² at its outer end; B is the long leg of the syphon down which
the water flows when the syphon is set in action by pulling the chain e and
suddenly raising the piston C. These parts are all well known.
My invention is carried out as follows:-I make the top part of the syphon b
above the cylinder B' with a bracket 62 forming a guide for the upper part of the
piston rod D which passes therethrough in addition to passing through the usual
guide 3 in the top of the cylinder bl. The piston rod D is connected to the
operating lever E by means of two side links F F the ends of which are
respectively jointed to the forked end of the operating lever E and to a cross head
or cross pin G which is formed on or fixed to the piston rod D either above the
guide 6 as shewn in Figs. 1, 2 and 3, or between the two guides 62 63. By this
arrangement of parts the piston rod D is effectually guided and is not liable to
wear the guides sideways as by employing the side links F1 F as above described
the operating lever E does not cause any side strain on the piston rod D. In a
modification of my invention instead of employing the side finks F1 F2, I make
the forked end of the operating lever E with holes e³ (see Fig. 5) which engage
directly with the ends of the cross head or cross pin G of the piston rod D, the
said holes e in the forked end of the operating lever E being slotted slightly as
shewn in Fig. 5 to allow of the free movement of the cross head.
In another arrangement of my invention shewn by Figs. 6, 7, 8 and 9, the cross

page_text: head G is made slotted at its ends gg and the forked end of the operating
lever E is made with inwardly projecting pins e on which may be rollers e
engaging in the horizontal-slots g g of the cross head, so that, as the lever E and
piston rod D move up and down, the pin ends of the operating lever E can move
slightly to and fro in the slotted ends g¹ g of the cross head G and thus prevent
any side strain on the piston rod D.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a flushing cistern of the kind herein referred to, the employment of a
piston rod guide on the top of the syphon in addition to the piston rod guide in
the top of the cylinder and in combination with means substantially as described
For raising the piston to start the flush.
2. In a flushing cistern of the kind herein referred to, the combination, with
the piston and piston rod, of a piston rod guide in the top of the cylinder and the
guide 6 at the top of the syphon, the cross head G fixed on the piston rod, the
operating lever, and the links F1 F connecting the operating lever and cross head
together, substantially as hereinbefore described with referénce to Figs. 1, 2, 3
and 4 of the accompanying drawings.
3. In a flushing cistern of the kind herein referred to, the combination, with
the piston and piston rod of a.piston rod guide in the top of the cylinder and the
guide in the top of the syphon, the cross head G fixed on the piston rod, and the
forked operating lever E made with slotted ends engaging with the ends of
the cross head, substantially as herein before described with reference to Fig. 5 of
the accompanying drawings.
4. In a flushing cistern of the kind herein referred to, the combination, with
the piston and piston rod, of a piston rod guide in the top of the cylinder and the
guide in the top of the syphon, the cross head G fixed on the piston rod and
made with cross slots g' g3 in its ends, and the operating lever made with a forked
end engaging in said cross slots of the cross head, substantially as herein before
described with reference to Figures 6, 7, 8 and 9 of the accompanying drawings.
Dated this 25th day of August 1897.
