PROVISIONAL SPECIFICATION.
Improvements in Lavatory Basins and in Supports therefor.
I, PHILIP BRIGHT, of 2 Newgate Street, in the City of London, Engineer, do
hereby declare the nature of the said invention to be as follows:-
This invention relates firstly to the construction of lavatory basins of the kind
known as
"Tip-up" basins, that is to say basins which are turned or tilted on
horizontal axes when it is required to discharge their contents into the receiver
which communicates with the waste pipe, and the improvements under this head
are of the following character:-
Heretofore it has been customary to make the overflow passage in basins of this
kind at the front and immediately under the flange or projection which serves as a
handle for raising the front of the basin in the tilting operation. These overflow
passages rapidly become foul with soap and dirt and are very difficult to get at for
cleansing purposes, the overflow water also trickles down the outside of the front
part of the basin into the receiver, soiling both parts of the apparatus. I obviate
these objections by making the overflow at the back part of the basin just over the
end of the waste pipe, so that any liquid overflowing from the basin drops direct
into the waste pipe without trickling down the surface either of the basin itself or
the receiver; and instead of making the overflow as heretofore I make it in the
form of a projecting lip or spout the bottom of which is at such a distance below
the top of the basin that any excess of liquid is carried off by such lip or spout
before it can rise beyond a certain height. This form and arrangement of the
overflow is easy to clean and directs the discharge of the contents of the basin into
the outlet of the receiver without trickling down the basin, and the latter does not
require to be tipped up or tilted to so great an angle with the horizontal as basins
constructed in the ordinary way and there is therefore less danger of reversing the
basin altogether in the process of discharging its contents as sometimes happens
with present arrangements, whereby the basin is broken by striking against the
supply tap or valve, or against the ledge which is sometimes placed in the receiver
to carry the buffer or stop for the basin. And in order to prevent still more
effectually the reversal of the basin I provide it with an indiarubber or other
clastic buffer which, when the basin is tilted up into a certain position, comes
against the curved or inclined surface of the receiver.
In order to facilitate cleaning, I sometimes apply to the outlet of the receiver a
strainer or grating and seating of the following character :- make the recess for
the strainer or grating somewhat larger than the strainer or grating itself, but with
comparatively narrow projections of suitable shape extending radially inwards so
as to form steadying pieces for the circumference of the strainer or grating to bear
against. I also form the bottom of the recess with comparatively narrow suitably
shaped pieces projecting upwards, on which the underside of the strainer or grating
rests instead of resting directly on the bottom of the recess. The strainer or
grating may also be formed with comparatively narrow projections extending
radially outwards from its circumference so as to bear against the circumference of
the recess, and with other similar projections extending downwards and bearing
on the bottom of the recess.
The invention relates secondly to improvements in the construction of supports
for lavatory basins, whereby such basins, as well as their receivers and slabs of
marble or other material, can be easily adjusted in height or in horizontal position
within certain limits to suit various tastes or requirements. For this purpose I
make the iron or other supporting frames of a height suited to the least height at
which it is likely that it may be required to fix the basins and slabs, and I provide

page_text: cast iron or other suitable brackets to which the receivers are attached by lugs and
screw bolts. These brackets are provided with slots and the supporting frames
with other corresponding slots placed at right angles to those in the brackets; by
these means the receivers and basins can be adjusted vertically, and backwards or
forwards horizontally and be fixed in position by bolts passed through the said
slots. The slabs of marble or other material are similarly adjusted vertically to
suit the receivers and basins by means of bearers which are adjustably secured to
the supporting frames.
Instead of placing the buffer or stop to carry the preponderating weight of the
front part of the basin on the front part of the receiver or on the supply tap or
valve, I prefer to place it on a bracket in such a position that the upper edge of
the back part of the basin, or a lug or projection thereon, bears up against it from
below and in order to provide for irregularities or variations of form in the
basins I make the said bracket adjustable in position to suit such irregularities or
variations.
The supporting hook for carrying the main outlet pipe may also be made
adjustable on the supporting frames.

Improvements in Lavatory Basins and in Supports therefor.
I, PHILIP BRIGHT, of 2 Newgate Street, in the City of London, Engineer,
do hereby declare the nature of the said invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference .being had to the accompanying two sheets of
drawings, and to the letters and figures marked thereon, that is to say :-
::
This invention relates, firstly, to the construction of lavatory basins of the kind
known as <<
Tip-up basins, that is to say basins which are turned or tilted on
horizontal axes when it is required to discharge their contents into the receiver
which communicates with the waste pipe, and the improvements under this head
are of the following character :—
Heretofore it has been customary to make the overflow passage in basins of this
kind at the front, and immediately under the flange or projection which serves as a
handle for raising the front of the basin in the tilting operation. These overflow
passages rapidly become foul with soap and dirt, and are very difficult to get at for
cleansing purposes; the overflow water also trickles down the outside of the front
part of the basin into the receiver, soiling both parts of the apparatus. I obviate
these objections by making the overflow at the back part of the basin just over the
end of the waste pipe, as shown in Figure of the drawings (which represents a
section through a basin and receiver) so that any liquid overflowing from the
basin A drops direct into the waste pipe B without trickling down the surface
cither of the basin A itself or of the receiver C; and instead of making the over-
flow as heretofore, I make it in the form of a projecting lip or spout A¹ the
bottom of which is at such a distance below the top A² of the basin A that any
excess of liquid is carried off by such lip or spout A' before it can rise beyond a
certain height. This form and arrangement of the overflow is easy to clean and
directs the discharge of the contents of the basin into the outlet B of the receiver
without trickling down the basin, and the latter does not require to be tipped-up or
tilted to so great an angle with the horizontal as basins constructed in the ordinary
way and there is therefore less danger of reversing the basin altogether in the
process of discharging its contents than with present arrangements in which the
basin is sometimes broken by striking against the supply tap or valve, or against

page_text: the ledge which is sometimes placed in the receiver to carry the buffer or stop for
the basin. And in order to prevent still more effectually the reversal of the basin,
I provide it with an indiarubber or other suitable buffer D secured to a flange D'
on the said basin which buffer, when the basin is tilted-up into a certain position,
comes against the curved or inclined surface of the receiver C, as shown in dotted
lines in Figure 1.
In order to facilitate cleaning, I sometimes apply to the outlet B of the
receiver C a strainer or grating and seating of the following character :-I
make the recess E for the strainer or grating F somewhat larger than the strainer
or grating itself but with projections G (see Figure 2) of suitable shape projecting
radially inwards to form guides or steadying pieces for the circumference of the
strainer or grating F which latter is formed with narrow projections H extending
downwards so as to bear on the bottom of the recess E. Or, instead of forming
projections G extending radially inwards from the circumference of the recess E,
as in Figure 2, projections G extending radially outwards from the strainer or
grating F (as shown in Figures 1, 14 and 1B) may be employed. Figure 1 is an
underside view and Figure 1B a plan of the strainer or grating F which may also
be provided with narrow projections H, similar to those shown in Figure 2,
projecting downwards so as to rest on the bottom of the recess E. The bottom of
the recess E may also be provided with projections I extending upwards as shown
in Figures 1 and 1º, and if preferred, the recess E may be provided both with the
inwardly extending projections G and the upwardly extending projections J. By
either of these arrangements water channels J are left round the circumference of
the strainer or grating F, and the rush of water through them assists in keeping
the strainer or grating clean, and in preventing it from becoming set fast in
its seat.
It is obvious that the above described arrangements of the strainer or grating
are also applicable to the strainers or gratings of urinals, sinks, gullies and so
forth.
The invention relates, secondly, to improvements in the construction of supports
for lavatory basins whereby such basins, as well as their receivers, can be easily
adjusted in height or in horizontal position and their covering slabs of marble or
other material adjusted in height, within certain limits, to suit various tastes or
requirements. For this purpose I employ the arrangements shown in the drawings
in which Figure 3 is a side clevation of the framework supporting a lavatory basin,
the covering slab A' being shown in section, and Figure is a front elevation of
same showing parts of the framework for other similar basins, one at each side.
K are cast iron supporting frames of a height suited to the least height at which it
is likely that it may be required to fix the basins, such as A, and slabs such as A³.
Kare cast iron or other suitable brackets to which the receivers, such as C, are
attached by lugs L and screw bolts as shown. These brackets are provided with
slots K and the supporting frames K with other corresponding slots K³ placed at
right angles to those in the brackets K'. By these means the receivers and basins
can be adjusted vertically and backwards or forwards horizontally, and be fixed
in position by bolts M passing through the said slots. The slabs of marble or
other material A³ are similarly adjusted vertically, to suit the receivers and basins,
by means of bearers P which are adjustably secured to the supporting frames K
by bolts P passing through slots P in the bearers P and slots or holes in the
palms K of the supporting frames K.
Instead of placing the buffer or stop to carry the preponderating weight of the
front part of the basin on the front part of the receiver, or on the supply tap or
valve, I prefer to place it on a bracket, or other suitable support, in such a position,
say at Qin Figures 1 and 3, that the upper edge of the back part of the basin, or
a lug, or projection thereon, or the overflow lip thereof, as shown in the said
figures, bears up against it from below; and in order to provide for irregularities
or variations of form in the basins the said bracket or other support may be made
adjustable in position to suit such irregularities or variations.

page_text: Figure 5 is an elevation and Figure 6 a plan of a crossbar provided with
slots K³ similar to those indicated by similar letters of reference in Figure 3.
Such cross bars may be connected to the longitudinal bearers P by bolts and nuts
as shown and employed as bearers for the receivers in cases where the frames K
can be dispensed with.
Similar letters of reference relate to like parts in all the figures of the drawings.
The supporting hooks R for carrying the main outlet pipe may also be made
adjustable on the supporting frames K as shown.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First Constructing "Tip-up" lavatory basins with an overflow and discharge
passage in the form of a lip or spout as herein before described, and illustrated in
Figure 1 of the drawings.
Second Constructing a "Tip-up" lavatory basin with an elastic buffer so placed
as to come in contact with the receiver and prevent the basin from being tilted-up
beyond a certain position as hereinbefore described, and illustrated in Figure 1 of
the drawings.
Third Constructing the strainers or gratings with projections extending down-
wards or radially outwards, or both downwards and radially outwards, as herein-
before described, and illustrated in Figures 1, 14, and 2 of the drawings and for
the purposes specified.
Fourth Constructing the recesses for receiving the strainers or gratings with
projections extending upwards, as in Figures 1 and 1º, or radially inwards as in
Figure 2, or both upwards and radially inwards as hereinbefore described, and for
the purposes specified.
Fifth Constructing the supports of lavatory basins so that the receivers con-
taining the basins and the covering slabs of marble or other material or either of
these parts can be adjusted and secured in position as hereinbefore described, and
illustrated in Figures 3, 4, 5 and 6 of the drawings.
