Improvements in or connected with Pedestal Water-closets.
We, ROBERT GEORGE LAING BURN and JOHN MACDONALD, trading as Burn and
Baillie of 14 Newcastle Street, Farringdon Street in the County of Middlesex and of
63 and 65 Hanover Street and 34 Alva Street, Edinburgh in the County of Midlothian
North Britain Sanitary Engineers do hereby declare the nature of this invention to be.
as follows:
"
Our invention refers to improvements in pedestal water closets of the types known
" and
as "Wash out or "Flush out" and also to that known as "Hopper closets
may be called dual pedestal closets, for which purpose we arrange the trap of the
closet sufficiently high to keep a small quantity of water in the bottom of the pan
or basin so that the latter is always kept wet and thus soil is prevented from
adhering to it.
::
According to our invention the bottom of the pan or basin is made somewhat
flatter and more horizontal than is in the so called hopper pan before referred to
and instead of having a cavity as in "wash out pans, from which soil requires to
be forced or thrown slightly upwards by the water flush before it enters the trap,
very frequently leaving a quantity on the front wall of the outlet, the bottom slopes
gradually downwards to the trap. The flushing action is therefore entirely down-
wards and in consequence of the trap being so much nearer to the flushing rim than
in the usual hopper closet, the flush enters it with greater force or pressure, and
thus changes its contents more effectively.
The basin is made as sanall as possible and the flushing rim arranged so that the
whole surface is well flushed and the contents rapidly discharged down the trapped
outlet towards the back. We make the water closet with enclosure basin and trap in
one piece of earthenware.
We also make it with lead trap for use inside a house or where it is to be con-
nected to a lead soil pipe.
In order to improve the appearance of the outlet in this case, instead of making
the lead trap reach to the basin a portion of the earthenware trap already referred
to is made in one piece with the basin and enclosure and thus as far as the bend at
the bottom of the trap, the outlet is of earthenware.
The basin and outlet are bedded inside of a lead cone connected to the lead trap.
The lead cone arrangement has long been in use but we believe to be new the
application of a bent outlet in this connection so as to shew earthenware as far down
into the trap as possible.

COMPLETE SPECIFICATION.
Improvements in or connected with Pedestal Water-closets.
We ROBERT GEORGE LAING BURN, and JOHN MACDONALD, trading as Burn and
Baillie, of 14 Newcastle Street, Farringdon Street in the County of Middlesex and of
63 and 65 Hanover Street and 34 Alva Street Edinburgh in the County of Midlothian,
North Britain Sanitary Engineers do hereby declare the nature of this invention
and in what manner the same to be performed to be particularly described and
ascertained in and by the following statement :-
Our invention refers to improvements in pedestal water closets of the types known

page_text: as
"wash out or "flush out" and also to that known as hopper closets and may
be called dual pedestal closets, for which purpose we arrange the trap of the closet
sufficiently high to keep a small quantity of water in the bottom of the pan or basin
so that the latter is always kept wet and thus soil is prevented from adhering to it,
and the invention will be best understood by describing same with reference to the
accompanying drawing which is a sectional elevation of a dual pedestal closet
constructed according to our invention.
According to our invention the bottom of the pan or basin is made as shewn in
the drawing somewhat flatter and more horizontal than it is in the so called hopper
pan before referred to and instead of having a cavity as in "wash out"
pans from
which soil requires to be forced or thrown slightly upwards by the water flush before
it enters the trap, very frequently leaving a quantity on the front wall of the outlet,
the bottom slopes as shown gradually downwards to the trap. The flushing action
is therefore entirely downwards, and in consequence of the trap being so much
nearer to the flushing rim R than in the usual hopper closet, the flush enters it with
greater force or pressure, and thus changes its contents more effectively.
The basin is made as small as possible and the flushing rim K arranged so that
the whole surface is well flushed and the contents rapidly discharged down the
trapped outlet S towards the back. We make the water closet with enclosure A,
basin B, and trap T in one piece of earthenware. We also make it with lead trap
for use inside a house or where it is to be connected to a lead soil pipe. In order to
improve the appearance of the outlet in this case instead of making the lead trap
reach to the basin a portion of the earthenware trap already referred to is made in
one piece with the basin and enclosure, and thus as far as the bend at the bottom of
the trap the outlet is of earthenware.
The basin and outlet are bedded as shown in drawing by dotted lines inside of a
lead cone connected to the lead trap.
The lead cone arrangement has long been in use, but we believe to be new the
application of a bent earthenware outlet in this connection so as to, show earthen-
ware as far down into the trap as possible. The enclosure A may in some cases be
dispensed with, and the water closet supported by other arranged-support..
-
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
First In pedestal water closets the pan or basin of the section described and
illustrated with reference to the drawing.
Second: In pedestal water closets the flushing rim Rin combination with the
trapped outlet S, trap T of the section shown together with enclosure A and basin B
made in one piece of earthenware substantially as and for the purposes set forth.
Third: In pedestal water closets the basin B of the section shown, bedded in lead
cone substantially as set forth.
:
Fourth In pedestal water closets the arrangement of the pan or basin B in
combination with the enclosure A substantially as and for the purposes hereinbefore
described and illustrated with reference, to the accompanying drawings together with
any mere modification thereof.
