PROVISIONAL SPECIFICATION.
Improvements in Lavatories.
I, OSCAR ELPHICK of Doulton & Cos. Sanitary Engineering Works Albert Embank-
ment in the County of Surrey, Engineer do hereby declare the nature of this inven-
tion to be as follows:-
In lavatories as at present constructed in which the water is let out at the bottom of
the basin it is found that the soap-suds stick to the sides of the basin and also
around the hole at the bottom. The object of this Invention is to remedy these
objections.
I form the top of the basin with a lip projecting inwards forming a channel around
the basin and I connect the supply pipe or pipes to this channel so that the water in
entering fills the channel and escaping by slits or holes sweeps down the sides of the
basin and removes any soap-suds which may be adhering. Where hot and cold water
are both laid on I connect both supply pipes to the channel preferably at opposite
sides to make the apparatus compact.
In order to prevent the soap-suds from sticking around the outlet I dispense with
the usual metal plug and metal seating and form the plug of earthenware ground to
an earthenware seat in material of which the basin is made. Preferably 1 make the
earthenware plug hollow and carry it up to the highest water level so that it also
forms an overflow.

Improvements in Lavatories.
I, OSCAR ELPHICK of Doulton & Cos. Sanitary Engineering Works, Albert Embank-
ment, in the County of Surrey, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
In lavatories as at present constructed in which the water is let out at the bottom
of the basin it is found that the soap-suds stick to the sides of the basin and also
around the outlet.
The object of this invention is to remedy these objections.
I form the top of the basin with a lip projecting inwards forming a channel around
the basin and I connect the supply pipe or pipes to this channel so that the water in
entering fills the channel and escaping by slits or holes sweeps down the sides of the
basin and removes any soap-suds which may be adhering. Where hot and cold water
are both laid on I connect both supply pipes to the channel preferably at opposite sides
to make the apparatus compact.
In order to prevent the soap-suds from sticking around the outlet I dispense with
the usual metal plug and metal seating and form the plug of earthenware ground to
an earthenware seat in material of which the basin is made. Preferably I make the
earthenware plug hollow and carry it up to the highest water level so that it also
forms an overflow.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of a lavatory basin constructed in accordance with my

page_text: Figure 3 is a section on the line 3, 3, in the same figure.
Figure 4 is an horizontal section on the line 4, 4, in Figure 3.
Figure 5 is a plan of the hollow waste plug.
a is the inwardly projecting lip of the basin which overhangs so as to enclose a
passage around the basin into which passage hot and cold water can be admitted from
pipes b and c by depressing the valve spindles d and e. The passage is open on the
underside, either with one slit extending entirely around the basin or with a number
of enlongated or other holes. f is the hollow waste plug, it is ground into its place
at the bottom of the basin, it is open at the top and serves as an overflow. fi is a
stem by means of which the waste plug may be lifted to empty the basin. g is a foot
piece to which the basin is fixed by bolts and h is the waste pipe. ii are receptacles
for soap.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A lavatory basin with lip a and water supply arranged as herein described.
2. A lavatory basin with hollow earthenware waste plug f ground into a seat at
the bottom of the basin as herein described.
3. A lavatory basin substantially as represented by the annexed drawings.
