siphon is started and the flush set in opera-
tion. Nearly all of the water drains through
the siphon,and that portion remaining therein
passes downward through opening K' in the
5 supply-pipe, so that all water is drained from
the cistern. Valve L opens communication
between supply-pipe K and drain-pipe R, so
that the water remaining in pipe K empties
therethrough, as does also the residue of the
io cistern-water, as just explained Leg II of
the siphon is open at its upper end and pro-
vided with valve J, so that if float-arm Q or
valve P should fail to operate to shut off the
supply the water would simply overflow into
15 the siphon, and thence downward through
the flush-pipe instead of overflowing the cis-
tern. The closing of the upper end of the
siphon-leg is simultaneous with the opening
of its lower end, so that the action of the si-
20 phon is in no way impaired.
A flushing apparatus is thus provided in
which no water is permitted to stand in the
cistern or to remain in the cistern-supply
pipe,and thus all danger of freezing is avoided.
25 Having thus fully described my invention,
what I claim, and desire to secure by Letters
Patent, is-
An improved water-closet and flushing ap-
paratus comprising a cistern, a supply-pipe
therefor, a weighted vertically-movable arm, a 30
valve in the supply-pipe actuated by said arm,
a siphon-discharge for the cistern, a valve
for closing the siphon,mechanism arranged in-
termediate said siphon-valve and the weight-
ed arm, whereby the weighted arm serves to 35
hold said valve normally open, the crank-
shaft suitably supported and connected at
one end to said intermediate mechanism, and
a depressible closet-seat adapted to actuate
the opposite end of the crank-shaft, whereby 40
when the seat is depressed the water-supply
is opened and the siphon is simultaneously
closed, substantially as shown and described.
In testimony whereof I affix my signature
in presence of two witnesses.
