PROVISIONAL SPECIFICATION.
Improvements in and relating to Water-closet Basins.
I, JOHN SMITH BUICK, of the firm of Charles Buick and Sons, of Hilton
Fireclay Brick and Tile Works, Alloa, Clackmannanshire, do hereby declare the
nature of my invention to be as follows:-
This invention has reference to and comprises special improvements in the inlet
or distributing water orifices or ducts of pedestal or other wash out water-closet
basins, whether made of fireclay, porcelain, or metal, for the purpose of the better
distribution and action of said water for flushing and cleansing the basin..
The nature and novelty of the improvements consist in introducing the flushing.
water to the upper part of the water-closet basin by three inlet openings (instead
of by only one or two openings as heretofore). That is having one central.
opening, leading direct into the fan, and two openings, one on each side of this
central one, leading laterally into and round the flushing rim to wash down the
general inner surface and sides of the body of the basin. One construction and
arrangement of these improvements consists in leading the water from the ordinary
service cistern or pipes of the house into a faucet formed on an outer longitudinal
chamber at the upper part of the basin nearly on the level of the inner flushing,
rim; and in forming three ports or ducts leading from this outer chamber, a central.
one leading direct into the upper part of the ordinary fan, and the other two, one
on each side leading laterally direct or tangentially into the ordinary open or
close flushing rim, round the inner upper edge of the basin, these rims flushing;
down the inner surface of the basin either by their lower open annular groove, or
by jets or orifices. These three openings or ports might be either of round, oval,.
rectangular, or other shape, and in any case have separating walls or divisions
between them to direct the water into their respective channels of the fan and
flushing rim. In the case of the flushing rim being open below, the outer end of
the fan or other deflector might be formed or fitted opposite the side openings, to
direct the side jets of water round the flushing rim.
The central opening might further be divided into three or more stream orifices
beyond the inlet port within the fan by having two or more divisions in it, so as
to spread a part of the water direct down, and a part or parts laterally sideways,
to cause the fan to more effectually flush the back or surface of the basin on which
the fan is fitted.

Improvements in and relating to Water-closet Basins!
1, JOHN SMITH BUICK, of the firm of Charles Buick and Sons, of. Hilton
Fireclay, Brick and Tile Works, Alloa, Clackmannanshire, do hereby declare the
nature of my invention and in what manner the same is to be performed. to..be.
particularly described. nd ascertained in and by the following statement in writing,
that is to say:
This invention has reference to and comprises special improvements in the inlet
or distributing water orifices or ducts of pedestal or other wash out, water closet
basins, whether made of fireclay, porcelain or metal, for the purpose of the better.
distribution and action of said water for flushing and cleaning the basin..

page_text: And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings, in which the same reference letters
are used to indicate corresponding parts in all the figures where shown.
Figure 1 is a sectional clevation and Figure 2 a plan view of a water closet
basin as constructed of fireclay or porcelain in accordance with one arrangement
of my improvements.
Figures 3 and 4 are views corresponding to Figures 1 and 2 of another or
modified arrangement of my improvements, while
Figures 1 and 3 are detached sectional views taken on the lines 1-1 and 2—2
in Figures 2 and 4, respectively, showing the water inlet ducts or ports.
Referring to these drawings.-The improvements consist in introducing the
flushing water to the upper back part of the water-closet basin A. by three inlet
openings be, c', from the same inlet orifice chamber a (instead of by only one or
two openings as heretofore). That is having one central opening leading direct
into back space of the fan, and two openings, e, one on each side of the central
one leading laterally into and round the space A2, in the upper lip of the flushing
rim A to wash down the general inner surface and sides of the body of the
basin A. One construction and arrangement of these improvements as shown in
these drawings consists in leading the water from the ordinary service cistern or
pipes of the house into a faucet a formed on an outer longitudinal chamber a at
the upper part of the basin A, nearly on the level of the inner flushing rim A';
and in forming three ports or ducts be c¹ leading from this outer inlet chamber a,
a central one leading direct into the upper part of the ordinary fan space f¹, and
the other two c c¹ one on each side leading laterally direct or tangentially into the
ordinary open or close flushing rim AA round the inner upper edge of the
basin A, these rims flushing down the inner surface of the basin either by their
lower open annular groove A² as shown in Figures 1, 2, and 14, or by jets or
orifices d from the close rim space A as in Figures 3, 4 and 44. These three
openings or ports b, c, c', might be either of round, oval, rectangular, or other
shape, and in any case have separating walls or divisions was in Figures 3, 4 and 34
or partial divisional separating walls was shown in Figure 1 which is a section
through the fan space and as dotted-in in Figures 1, 2 and 14, between them to
direct the water into their respective channels of the fan and flushing rim A', A³.
In the case of the flushing rim A' being open below as in Figures 1, 2, and 1ª,
the outer end of the fan or other deflector might be formed or fitted opposite
the side openings c, c¹, above the dividing part w to direct the side jets c, c', of
water round the flushing rim A', as indicated by the arrows at ". Or in the case
of the rim A being closed as in Figures 3, 4 and 34, the part w³ of the rim A'
between the divisions w is made to form the fan f and flush the back of the closet
downwards as indicated by the arrows in Figure 3 to flush the water and soil
forwards down the inlet front opening P of the siphon pipe P, P. The central
opening might further be divided into two, three, or more stream or additional
orifices at 6 beyond the inlet port b within the fan by having two or more
divisions or holes in it, through the dividing part w¹, so as to spread a part of the
water direct down, and a part or parts laterally side-ways, to cause the fan
more effectually flush the back or surface of the basin on which the fan is fitted.
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 1
claim is
to
First. The constructing of water-closet basins with three inlet flushing openings
or channels, with separating walls or divisions between them, leading from a central
orifice chamber, at the back of the basin, a central one leading into the fan or its
equivalent, and two side openings or channels leading laterally into and around the
flushing rim, substantially as and for the purposes herein described in reference
to and shown in the accompanying drawings.

page_text: Second. In water-closet basins, the forming of two side and one central inlet
flushing opening or channel with separating walls or divisions between them, and
subdividing the central opening into a number of stream orifices at the fan part,
substantially as and for the purposes herein described in reference to and shown in
Figures 1, 2, and 1ª of the accompanying drawings.
