PROVISIONAL SPECIFICATION.
Improvements in or connected with Pedestal Water Closets.
I, ROBERT GEORGE LAING BURN, of the firm of Burn and Baillie, of
14 Newcastle Street, Farringdon Street, in the City of London, and of 63
and 65 Hanover Street, and 34 Alva Street, Edinburgh in the County of Mid-
lothian North Britain, Sanitary Engineers, do hereby declare the nature of this
invention to be as follows:
-
My improvements refer particularly to that type of closet described in the
Specification of Burn and Macdonald's Patent dated 19th November 1889
No. 18509.
According to my present invention I form in connection with the flushing rim
or in connection with the inlet passage to the flushing rim a secondary passage or
passages leading to the lower interior part of the pan and entering either at or
below the water line at the trapped outlet of the pan, so that the flushing water
as it travels through the flushing rim also travels through the secondary passage or
passages.

COMPLETE SPECIFICATION.
Improvements in or connected with Pedestal Water Closets.
I, ROBERT GEORGE LAING BURN, late of the firm of Burn and Baillie,
of 14 Newcastle Street, Farringdon Street, in the City of London, and of
63 and 65 Hanover Street, and 34 Alva Street, Edinburgh in the County of Mid-
lothian, North Britain, but now of 23 and 24 Charing Cross, in the County of
London, Sanitary Engineer, 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 :-
My improvements refer particularly to that type of closet described in the
Specification of Burn and Macdonald's Patent dated 19th November 1889,
No. 18509.
According to my present invention, I form in connection with the inlet passage
to the flushing rim a secondary passage or passages leading to the lower interior
part of the pan and entering below the water-line at the trapped outlet of the pan,
so that the flushing water as it travels through the flushing rim also travels through
the secondary passage or passages.
My invention will be readily understood by reference to the accompanying
drawing;
Fig. 1 thereon illustrating a closet pan in vertical section and shewing one side
thereof, while
Fig. 2 shews a view of the other side of the same closet, all constructed according
to my invention.
A indicates the position of the inlet passage for the flushing water: B is the
flushing rim. C, Fig. 1, is a secondary passage, extending directly from the
inlet A around the outer side of the pan as is shewn by the dotted lines, being
generally formed in a piece with the said pan. This secondary passage is formed
with a branch C' opening into the pan at C² below the water level, while the

page_text: termination of the passage enters the pan in front and below the water level at C³.
A passage D leading directly from the inlet A. also extends around the other side
of the pan as is shewn in dotted lines at Fig. 2 and enters into and terminates
at the side of the pan at D² opposite the passage way C² below the water
level.
By these means, at the same time that the water enters the flushing rim B,
a force of water is applied below the water level of the trapped outlet at three
several places, marked C2 C3 D2, whereby sufficient force is immediately obtained
to give motion to the body of water in the pan, and accelerate its passage through
the trap.
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 I am
aware it is not new to supply water by a passage leading from the flushing rim, but
such arrangements are disadvantageous as not sufficient pressure is thereby
obained; I therefore claim.
In pedestal water closets, the secondary passages C, C, and D, extending and
leading directly from the main inlet A and all opening into the pan below the
water level of the trapped outlet, all constructed and acting substantially as and
for the purposes herein set forth, together with any mere modification or modifi-
cations thereof.
