PROVISIONAL SPECIFICATION.
Improvements in Traps for Closets, Urinals, Lavatory Basins, and
the like.
I PETER THOMAS ARDLEY of No. 6ª Stopford Road Manor House Estato
Walworth, in the County of Surrey Plumber do hereby declare the nature of this
inventi:n to be as follows:-
The object of this invention is to prevent syphonage of traps to water closets
lavatories & urinals and other like places and to abolish the anti syphon pipe now
in use and in substitution therefor.
It consists of a syphon of brass or other metal one end of which is let into the
air shaft of the crown of the trap or near thereto and the other end is enclosed
with a cup shaped screw connexion having a for larger if required aperture.
This the centre to admit air which cup shaped screw connexion contains an india
rubber ball for sealing such aperture and so that on the discharge emptying or
flushing of the w.c. lavatory or urinal the vacuum thereby caused is immediately
filled by a fresh intake of air through the aperture in the said screw connexion of
syphon. The ball being lifted by the suction occasioned by such discharge
emptying or flushing on the completion of the intake the ball resumes its place in
the cup shaped screw connexion effectually sealing the aperture.
A cross bar is inserted in the pipe to prevent the ball passing over the top of
syphon.

PETER THOMAS ARDLEY 6ª Stopford Road Manor House Estate,
Walworth, S.E. in the County of Surrey, Plumber, 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 :-
The above invention is to do away with the anti syphonage pipe absolutely for
traps, closets, urinals, lavatory basins & the like.
The above will be either in cast or galvanized iron brass gun metal or any other
substance as a syphon fixed on the crown of the traps or other parts of the soil or
other pipes with either rubber ball spindle ground in or other kind of valve
enclosed in brass or other metal case at the end of the syphon which immediately
the flush of water has passed the trap causes a vacum and immediately opens the
said valve and allows an inrush of fresh air and immediately seals itself against
the sewer gas or other obnoxious sinells from escaping into either w.c.'s houses or
dwellings thereby doing away with the anti syphonage entirely, which is now carried
above the roofs of houses.

page_text: A-Rubber ball spindle or other valve.
B-Brass or other seating for valve.
C-Bar or other guide to prevent ball from passing over top of syphon.
D-Syphon either of brass or other material.

invention & in what manner the same is to be performed, I declare that what I
claim is

air never before used for sanitary appliances viz. traps, closets, urinals lavatory
basins and the like with brass connexions to contain either of the aforesaid valves.
