New or Improved Lining for Lavatory Basins, the Washing-up
Wells or Public-house Counters, and the like.
I, FREDERICK CHRISTOPHER ARMSTRONG, of 40, Church Road, Brixton, London, .
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:-
5 It is well known that in lavatory basins for example where overflow passages are
provided such passages are liable to become choked by soap-suds, scum and the
like, either in the passages themselves or in the strainers or gratings which lead
to them, and that when that occurs, and the fact is not observed, a leaky or im-
perfectly closed tap will cause the basin to overflow if the waste-plug is left in.
Also that the washing-up wells of public-house counters, which are not generally
provided with overflow passages on account of their special liability to get choked
up; are very liable indeed to overflow by reason of the waste-plug being left in
with leaky or imperfectly closed taps over them.
The object of the present invention is to provide means whereby the danger of
5 overflow of lavatory basins, public-house counter wells and the like is very con-
siderably reduced if not wholly obviated; and for this purpose I employ in connec-
tion with such basins, wells, and so forth, inner linings, or false basins or wells,
of somewhat smaller dimensions than the basins or wells in which they are placed,
preferably, but not necessarily provided with waste plugs at their bottoms for
emptying them when required.
And in order that the said invention may be fully understood I will proceed
to describe the same with the aid of the accompanying sheet of drawings which
represents sectional elevations of basins or wells with my invention applied thereto.
A, Figure 1 is the ordinary basin or well provided with the usual waste-pipe B,
the waste-plug being removed therefrom. C is the inner lining, or false basin
or well forming the subject of the invention, and which may be made of metal
or other suitable material. Dis the waste-plug at the bottom of same situated
preferably over the waste-pipe B, of the basin or well A. E are distance pieces or
studs to maintain the lining C as nearly as may be concentric with the basin A.
It will be seen that the lining C is. somewhat shallower than the
basin A, and it will be understood that in the event of the lining C
becoming full and its contents overflowing, the overflow will pass over the edge of
-the lining-C before the-level-of the liquid can-reach-the-upper edge of the basin A,
will flow down in the space between C and A, and will escape by the waste-
pipe B.
The lining C is preferably provided with handles, finger holes or other devices
at its upper part to facilitate its removal from the basin A for the purpose of
cleaning.
Instead of the overflow being passed over the upper edge of the lining C, holes F
Oor gratings F' may be provided in the sides of the lining at suitable denths below

page_text: the upper edge of the escape of the overflow into the space between the lining
and the basin.
Instead of being made shallower than the basin or well A, as shown in Figure 1,
the lining C may be carried up to the top of the same and be supported by a lip A
as shown in Figure 2, holes or other openings or gratings F, F1 or F2 being made
in the side of the lining for the escape of overflowing liquid as described in refer-
ence to Figure 1.
It is obvious that the waste-plug at the bottom of the lining C may be dispensed
with if preferred, the said lining being in that case removed from the basin A,
when it is required to empty it.
It will be seen that the above described arrangements render lavatory basins,
washing-up wells and the like entirely independent of the usual overflow passages
or pipes because the waste-pipe B is always open to carry away any overflow, and
being readily got at for cleaning is not so liable to get choked up as such passages
or pipes, which are in most cases crooked and difficult to get at for cleaning.
Similar letters of reference relate to like parts in both figures of the drawings.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manuer the same is to be performed, I declare that what I
claim is
First. In connection with a lavatory basin, washing-up well of a public-house
counter, or the like, the employment of an inner lining or false basin or well
constructed and operating substantially as described.
Second. An inner lining for use in connection with a lavatory basin, washing-up
well of a public-house counter or the like, provided with distance pieces or studs
for the purpose of maintaining a free space between the said lining and the basin
or well in which it is placed, substantially as described with reference to the
accompanying drawings.
Third. An inner lining for use in connection with a lavatory basin, washing-up
well of a public-house counter, or the like, provided with distance pieces or studs E
and with means for enabling its contents to overflow into the space between the
Ening and the basin or well in which it is placed, the said lining being provided
or not with a waste-plug, substantially as described with reference to the accom-
panying drawings.
Fourth. An inner lining for use in connection with a lavatory basin, washing-
up well of public-house counter, or the like, constructed, adapted, and operating
substantially as described.
Bated this 24th day of January 1899.
