Improvements in Automatic Flushing Apparatus for House Drains,
Sewers, Urinals, Water Closets, and the like.
I WILLIAM SPIERS FREEMAN of Invicta Works Otford Kent Mechanical
Engineer do hereby declare the nature of this invention to be as follows :-
The syphon itself is similar in principle to Fields Patent No. 3747 1875. My
improvements thercon will be noted upon reference to the drawing and consist of
(1) A cast iron self contained trapping box T. B.
(2) A circular deflector D in the centre of the above trapping box.
(3) A rim R round the top of the above trapping box (round which said rim the
floor of the flushing chamber is finished to form a sump S. S.
(4) An iron standard St (fixed to the above named trapping box) & having
attached thereto a valve V kept closed by a shot weighted copper ball C. B which
said ball will rise when partly immersed in the water supplied to the chamber by
the pet cock P (allowing a rush of water to ensure the syphon going off). On this
happening the weighted ball C: B drops, shutting off the rush of water through
valve V.
The other letters indicate H handle-C. cover-L lip to centre leg or dip
