Improvements in Water Closet Bowls.
I, JOHN CULVER BEEKMAN, Doctor of Medicine, of No. 21 West 122nd Street
in the City and County of New York, in the State of New York, United States
of America, 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 invention relates to improvements in water closet bowls, and has for its object.
the provision of a second flush, by which that part of the bowl in. the vicinity of
the discharge conduit, receives, after the first flush, a second flush in such a direction
as to effect a thorough cleansing of the bowl.
A practical embodiment of my invention is represented in the accompanying
drawing, in which―
Fig. 1 is a vertical central section taken through the flush inlets and the discharge
conduits from the bowl.
Fig. 2 is a transverse vertical section through the line of Fig. 1, and
Fig. 3 is a top plan view of the bowl, taken partly in section through the
line yy of Fig. 1, to more clearly show the construction of the second Hush
mechanism.
A represents the body of the bowl, provided with a flushing rim a, extending
around its upper portion, and having flushing orifices a formed at intervals in its
lower portion. The inlet chamber B receives the flushing water from the supply
pipe 6 leading to a suitable supply tank, not shown, and within the chamber B the
inner wall of the flushing rim a presents a wedge-shaped projection toward the
direction of the inflowing stream of water, which projection serves to separate
the stream of water, and direct it in opposite directions around the flushing
rim a.
Between the inlet chamber B and the upper end of the discharge conduit D,
there is provided a laterally enlarged and thickened portion C, within which a
second flushing chamber is formed and supplied as follows :—
C
The body portion of this second flushing chamber connects, at its outer end,
with a supply pipe e, which leads to a suitable flushing tank, not shown. From
the body portion of the second flushing chamber, extend conduits e², preferably
curved to the right and left, which open downwardly, as shown at c³, into the
upper portion of the discharge conduit D at the right and left of the centre.
Another portion of the flushing chamber, separated from the laterally extending
conduits by partitions e, extends toward the bowl, and opens downwardly through
an elongated mouth c into the upper central portion of the discharge conduit D.
As here shown, the flushing chamber c, from a substantially cylindrical form at
the point where it connects with the pipe c', gradually flattens, and increases in
width as it extends toward the bowl, and the water therefrom will be discharged in
three separate streams through the openings c³ co, in such a position, and in such
direction, as to effect a thorough cleansing of that portion of the bowl around the
upper end of the discharge conduit D.
It is obvious that the supply pipes and may lead either to the same tank
or to separate tanks, and that they may be supplied by independent valves under
the control of independent operating devices, or they may be supplied by an auto-
matic double flush tank under the control of a single operating device of the
general construction shown and described in the Specification and drawings
of another application for Patent lodged on the same day as the present
application.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is.
1. A water closet bowl provided with a flushing. device adapted to discharge
water around the rim, of the bowl, and a second, flushing device consisting of a
Alushing chamber provided with-water conduits leading to the right and left, and
with a water conduit intermediate of those leading to the right and left, the said
conduits opening into the upper portion of the discharge conduit above the overflow
from the bowl, substantially as set forth.
2. A water closet bowl provided with an inlet chamber through which the water
is admitted to the flushing rim, and a second flushing chamber formed in the-
thickened portion of the rim below the inlet chamber B, and, above the overflow
from the bowl of.the discharge conduit, substantially as set forth.
Dated this 26th day of May 1891.
