COMPLETE SPECIFICATION
Improvements in Syphon Flushing Cisterns for Sanitary Purposes.
1, EDWARD JAMES FINCH of No. 9 Buckingham Street, Strand, Sanitary,
Hydraulic and Ventilating 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:-
5. The object of this invention is to provide an intermittent Self Acting Syphon
Flushing Cistern and a Manual Syphon Flushing Cistern for Sanitary purposes, put
into operation by a Ball or Dribble Cock or by means of a Handle or ring attached
to a rod, wire or chain.
See Drawings (One Sheet).
Figure 2 is a Sectional Elevation of my Syphon Flushing Cistern.
10. By pulling the handle, or Ring a, attached by the rod or chain b, to the lever
having a balance weight, and its falcrum at d; the rod e, and plate or piston
descends into the cylinder or chamber g, on to the stops, h, h, h.
15. The water confined in the cylinder or chamber g, by the cover i, is forced by
the descending plate or piston f, through the neck or aperture k, and directed by the
lip or projection 1, into the syphon m, and over the bend n.
20. This causes a suction within the syphon m, which lifts the flap o, working on
the hinge p, and holds it against the stop barq, until the cistern is empty.
25. The flap o then falls by its own weight on to the seating r.
30. The Ball taps then opens and re-charges the cistern.
35. For intermittent flushing, the handle or ring a, the rod or chain b, the lever c,
the weight, the rod e, the plate or piston and the flap
o are not used.
40. The syphon m. remains out of action until the water flows over the bend n,
when the syphon empties the cistern. The ball cocks is replaced by a dribble cock if
required.
Figure 1, is a plan of my Syphon Flushing Cistern.
To be manufactured preferably in metal, plain, painted, galvanized, or enamelled,
(as required)

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed; I declare that what 1
claim is
Ist. In the manufacture and use of syphon flushing cisterns with the Cylinder or
chamber with the cover, the plate or piston / worked by the rod e, and lever c and
weight and stops h, h, h.
2nd. The neck or aperture k, with lip or projection 7.
ord. The self closing flap o, working on a hinge, placed in or under Syphons or to
work in connection therewith, and operated upon by suction.
4th. The method of providing a full or partial way for the passage of water through
the mouth of syphons by the means and in the manner aforesaid.
5th. The manufacture and use of the several novel adaptations or combination of
parts together forming my improvements in syphon Flushing Cisterns for Sanitary
purposes, or any mere modifications thereof.
In witness whereof I the said Edward James Finch have hereunto set my hand
