PROVISIONAL SPECIFICATION.
A New or Improved Syphon for Flushing Cisterns.
Alfred CliffORD Claremont House Hawley Road, near Dartford Kent
Plumber and Sanitary Engineer do hereby declare the nature of this invention to
be as follows:
The invention is illustrated in the two sheets of drawings accompanying this
specification and is shewn in three views Figures 1. 2 and 3. Figure 1 is a section
of cistern shewing the syphon in side elevation, Figure 2 is a section through
syphon and Figure 3 is an end view of syphon.
The syphon is a receptacle fan shaped in section A, and of any convenient
width attached to which is the top portion of discharge pipe C. The top of this
pipe is gradually enlarged so as to meet the width of A thus forming a funnel or
trumpet mouthed head B Fig. 3. This arrangement is cast or made in one piece of
metal or any other suitable material. The flap D is hinged to bottom of syphon
as shewn and is provided with a weighted lever E which is attached by a chain or
otherwise to a crank F the other end of which is attached to the pull ring by a
chain or wire.
The action is as follows, on the ring being pulled the crank F is placed in the
position as shewn in Fig. 2 by the dotted lines thus operating on the lever E and
causing the flap D to assume a perpendicular position (see dotted line) and forcing
the water into head of discharge pipe B. This head being enlarged is found to
be of great utility in increasing the syphonage. The face of flap D is slightly
hollowed out so as to grip the water.

Plumber 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 is illustrated in the two sheets of drawings as left with the
Provisional Specification and is shewn in three views Figures 1. 2 and 3.
Figure 1 is a section of cistern shewing the syphon in side elevation.
Figure 2 is a section through syphon and Figure 3 is an end view of syphon.
The syphon is a receptacle fan shaped in section A, and of any convenient
width, attached to which is the top portion of discharge pipe C. The top of this
pipe is gradually enlarged so as to meet the width of A thus forming a funnel or
trumpet mouthed head B Fig. 3. This arrangement is cast, or made in any other
manner or of any suitable material.

page_text: The flap or push plate D is hinged to bottom of syphon as shewn and is
provided with a weighted lever E which is attached by a chain or otherwise to a
crank F the other end of which is attached to the pull ring by a chain or wire.
The action is as follows, ou the ring being pulled the crank F is placed in the
position as shewn in Fig. 2 by the dotted lines thus operating on the lever E and
causing the flap D to assume a perpendicular position (see dotted lines) and forcing
the water into head of discharge pipe B. This head being enlarged is found to be
of great utility in increasing the syphonage. The face of flap D is slightly hollowed
out so as to grip the water. One great advantage in this cistern is the syphon A
being fan shaped, holds a body of water which when the syphonage stops falls to
the bottom of cistern and stops the noise caused by suction."
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
The fan shaped syphon, combined with the push plate and mode of working as
described in these specifications, and I do not confine myself to the exact shape as
shewn on drawings.
