Improvements in or relating to Lavatory Basins.
I, JAMES GEORGE STIDDER, of 13 Aquinas Street, Stamford Street, London-
S.E., Sanitary Engineer, do hereby declare the nature of my said invention to be
as follows:-
The object of my invention is to effect improvements in or relating to lavatory
basins, for the purpose of regulating the height of water in the basin and of
preventing the passage of effluvia from the overflow or waste pipes.
According to my invention I form the overflow passage with a trap preferably
integral with the basin, the overflow passage leading from the outlet or discharge
valve, grating, or passage, up the side to the trap, the lip of which is made level
with the greatest height to which the water is to be allowed to run into the basin.
In the outer wall of the trap I provide an opening for conveniently inspecting.
and cleansing the trap; a suitable fluid tight cover being fitted to the opening.

Improvements in or relating to Lavatory Basins.
I JAMES GEORGE STIDDER, of 13 Aquinas Street, Stamford Street, London
S.E. Sanitary Engineer, do hereby declare the nature of my said invention and
in what manner the same is to be performed, to be particularly described and.
ascertained in and by the following statement :-
The object of my invention is to effect improvements in or relating to lavatory
basins, for regulating the height of water in the basin, and preventing the passage
of effluvia from the overflow or waste pipes.
According to my invention I construct the overflow passage with a trap,.
preferably integral with the basin, the overflow passage leading from the outlet or
discharge valve, grating, or passage, up the side of the basin, to the trap, the lip.
of which is made level with the greatest height to which the water is to be allowed
to run into the basin.
In the outer wall of the trap I provide an opening for conveniently inspecting
and cleansing the trap; a suitable fluid-tight cover being fitted to the opening.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, being
sectional elevations showing four methods of carrying out my invention, and in
which similar figures of reference indicate corresponding parts.
Referring to Figs. 1, 2 and 3.-4 is the basin; 5 the overflow passage; 6 the
overflow trap; 7 is a passage for air to prevent syphon action when the basin.
overflows. 8 is a movable cap or cover fitted, fluid-tight, to an opening, for con-
veniently inspecting and cleansing the trap. 9 is a pipe or passage for carrying
away the surplus water overflowing from the trap.
The height of the water in the basin is regulated by the lip 10, over which the:

page_text: surplus water flows; the trap 6 effectually, preventing the passage of foul air from
the pipe or passage 9.
In Fig. 1. the discharge pipe is shown fitted with a plug valve 11, which
performs a similar function to that of the plugs 12 shown in Figs. 2, 3 and 4.
Fig. 4 illustrates the application of my invention to a lavatory basin discharging
directly over a trap outside the building, the lip 10 being arranged to limit the
quantity of water in the basin, the overflow in this case not requiring a trap.
From the foregoing description and the examples illustrated, it will be readily
understood that my invention can be applied, with obvious modifications to lavatory
basins of other forms.
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 :-
.
1. The improvements in or relating to lavatory basins substantially as and for
the purposes described.
2. The combination with lavatory basins, of a trap formed in, fitted to, or in
connection with the overflow passage, substantially as and for the purpose
described.
3. In lavatory basins of the description aforesaid the method of limiting the
height of the water by the height of the lip 10 of the passage 5, substantially as
hereinbefore described and illustrated by the drawings.
4. In combination with lavatory basins as aforesaid, the application and use of a
movable cover 8 to the trap, substantially as and for the purposes hereinbefore
described and illustrated by the drawings.
5. In combination with lavatory basins as aforesaid, the application and use of a
plug valve 11 fitted to the discharge pipe, substantially as herein before described
and illustrated by Fig. 1 of the drawings.
Dated 2nd April 1896.
