London do hereby declare the nature of this invention to bo as follows:-
By placeing valve in a chamber at outlet of trap thereby preventing foul air from
soil pipe going into basin.
The basin has a flat rim on top edge and two inlets for quick water supply, one
on either side the bottom of a concave form sloping to the back with outlet pipe to
connect to trap, it has two lugs with holes for fixing it to iron stand.
The trap is taper one half inch in diameter larger at outlet and fixed in bottom of
chamber joining outlet to soil pipe, and two lugs with holes for fixing to floor..
The chamber is oval shapo to allow space for valve to work also as ventilating shaft
with outlet to ventilating pipe, it has two lugs one on either side to forin guide to
valve when in motion, the cover (in two parts) is made moveable with hole for rod
attached to valve to pass through and fastened with two thumb scrows and made air
tight with india rubber packing.
The valve is made of metal tubo with increased size at bottom with vulcanized
india rubber round seat to form water tight joint on trap, with opening letting out
overflow from hasin to a given level into soil pipe, the upper part has a stopped end
with rod through cover of chamber connecting leaver raising same and letting in
water supply.
By those appliances the water in basin will rise to a given level ready for use, the
overflow rising in valve tube and passing to soil pipe, when the valve is raised
the contents of busin pass through the trap into soil pipe leaving the trap sealed hill
the valve drops by its own weight on its sent and the basin is charged ready
for use.

JOHN WEST Buildor's General Foreman 3 Glen Street Hampstead Road London
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:
By placeing valve in a chamber at outlet of trap thereby preventing foul air from
soil pipe going into basin.
The basin has a flat rim on top edge and two inlets for quick water supply one on.
either side the bottom of a concave form sloping to the back with outlet pipe to
connect to trap, it has two lugs with holes for fixing it to iron stand.
The trap is taper one half inch in diameter larger at outlet and fixed in bottom of
chamber joining outlet to soil pipe and two lugs with holes for fixing to floor.
The chamber is oval shape to allow space for valve to work also as ventilating shaft
with outlet to ventilating pipe it has two lugs one on either side to form guide to
valve when in motion the cover (in two parts) is made moveable with hole for rod
attached to valve to pass through and fastened with two thumb screws and made air
tight with india rubber packing.
The valve is made of metal tube with increased size at bottom with vulcanized
india-rubber round seat to form water tight joint on trap with opening letting
overflow from basin to a given level into soil pipe the upper part has a stopped end
with rod passing through cover of chamber connecting leaver raising same and letting
in water supply.
By these appliances the water in basin will rise to a given level ready for use the
overflow riseing in valve tube and passing to soil pipe when the valve is raised
the contens of basin pass through the trap into soil pipe leaving the trap sealed
and the valve drops by its own weight on its seat and the basin is charged ready
for use.

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
First. In making a chamber to receive valve and connecting same to air pipe.
Second. In making trap taper and fixing same at bottom of chamber connecting
soil pipe.
Third. In making valve with outlet for overflow from basin and placeing it over
outlet of tran.
