PROVISIONAL SPECIFICATION.
Improvements in Waste Fittings for Closets, Urinals, Sinks,
and the like.
JAMES HARRIS 2 Dunster Gardens Brondesbury London N.W. Architect, Surveyor
and Sanitary Engineer do hereby declare the nature of this invention to be as
follows:-
This invention consists in the simple construction and arrangement of an outlet
valve in connection with water closets and other sanitary purposes where the appliance
used is required to be entirely emptied of its contents and flushed with water and after
which to retain a requisite quantity of water in the pan or other apparatus for the
purpose of formning a sealed trap to prevent the ingress of sewer gas into the house
and the same is carried out and more fully explained by reference to the annext
drawing.

g weight or counterbalance. h ring for connecting valve with plug. i vent hole for
escape of sewer gas. j chain hinge attaching D-valve to pan. k. hole for receiving
plug lever.
It will be seen that the invention consists in the construction and arrangement of
the valve d which acts as follows. When the said valve is opened by means of the
plug it closes the escape holes i and allows the sewerage to pass out of the pan down
the soil pipe as desired and when the said valve returns to its closed position it pre-
vents the water from passing out of the Pan until it has reached its level or the height
of the valve and so forms a sealed trap. This invention may be used in modified ways
and is equally applicable to Urinals or slop sinks.

Improvements in Waste Fittings for Closets, Urinals, Sinks,
and the like.
JAMES HARRIS 2 Dunster Gardens Brondesbury London N. Architect and Surveyor
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 consists in the simple construction and arrangement of an outlet
valve in connection with water closets urinals sinks and the like purpose where the
apparatus used is required to be entirely emptied of its contents and flushed with water
after which to retain a requisite quantity of water in the pan or apparatus for the
purpose of forming a "sealed "trap to prevent the ingress of sewer gas into the house
and the same is carried out as follows.
Reference is now made to the drawings left with my provisional specification

improved valve to pan. k hole for receiving plug lever.

page_text: It will be readily understood that the invention consists in the construction and
arrangement of the valve D which acts as follows. When the said valve is opened
by means of the plug either by a vertical movement or outward direction it closes
the escape hole for gas i and allows the sewerage to pass out of the pan down the
soil pipe and when the said valve returns to its closed position it of course prevents
the water from passing out of the pan until it has reached its level or height of the
valve and so retains a certain quantity of water in the pan and forms a "sealed"
trap. I may if desired provide the said valve with a regulating plate for the
purpose of increasing the quantity of water to be retained in the said pan. This
said regulating plate is made to slide on the said valve. I may also weight the
said valve in any suitable manner. The opening and closing of the said valve may
be carried out by means of a pulley and weight; or by means of a crank as now in
use. A suitable cushion is provided either on the valve itself or on the pan consisting
of india-rubber or like material for the purpose of breaking the force of the valve
when opening & shutting. The said valve or D trap may be made of any suitable
metal or material.
This said D-trap or valve may be advantageously applied to Urinals.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed what I claim is and
desire to secure by letters patent is
(1) In closet or urinal pans the construction and arrangement of the valve D in
combination with the vent hole i cushioning f. substantially as described and for
the purpose set forth.
(2) In closet and urinal pans a valve or trap D for the purpose of allowing the
sewerage to pass out and which when closed will retain a certain amount of water in
the pan and form a sealed trap & overflow substantially as described and for the
purpose set forth.
