page_text: float will assume the position shown by the full lines, the ball valve 18 resting
on the seat 8; at the same time the arm 6 is depressed, which opens the supply
valve 5, and the water level rises above the bend in the siphon, which is imme-
diately thrown into operation to draw the water out of the tank through its longer
arm, and flush the closet bowl in the usual manner.
As soon as the chain is released, the counter-balance weights raise the ball valve
from its seat, and by admitting air, break up the siphon action and convert said
siphon into an ordinary overflow pipe. At the same time the water in the tank
rises, carrying the float with it, until it attains its normal level, when the float
closes the valve 5, where it remains until the chain is again drawn down.
In the form shown in Figs. 3, 4 and 5, I have provided the tank with an after-
flush. A chain A is attached to the seat of the closet and passes up over a pulley
secured to the edge of the tank, and is fastened to an arm B secured to the crank-
shaft B', which is connected with the float B2 that actuates the valve of the supply
inlet E. The chain is also fastened to a pivoted arm C which holds a ball D that
closes the outlet of the after-flush pipe which communicates with the siphon. The
after-flush pipe is located within a compartment D', the upper open end of which
is below the bend in the siphon....
:
As the seat of the closet is pressed down, it draws the chain over the pulley and
the arm B forward, which presses the float ball down and opens the valve on
supply pipe E, and the tank fills up. As the seat of the closet is pressed down,
it also draws the arm C and closes the outlet of the after-flush. As the valve of
the supply-pipe E is open, the tank fills with water till it overflows the
compartment D' enclosing the after-flush pipe, and the tank continues to fill until
it reaches the bend in the siphon, when the siphon commences to operate and empties
the tank except the water in the after-flush compartment. When the water has
lowered to the small holes G. in the siphon, the siphon gets air and ceases to operate.
The tank again fills up and siphons again, continuing regularly until the seat of
the closet is raised, which releases the arms iB and C, allowing the float ball to
rise and close the inlet, and the ball D to open the after-flush, and to flush away
any matter in the closet. .
Having, now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
1. A water closet flush tank, having a siphon formed integral therewith, the
whole. constructed in one piece, as and for the purpose set forth.
2. A closet flushing tank, comprising a fixed siphon provided with a valve seat,
an eduction valve in operative connection with said seat, an induction valve con-
trolled by a float, and means substantially as described for simultaneously operating
said valve as and for the purpose set forth.
3. A closet flush tank, comprising a stationary siphon provided with a valve seat,
a horizontal crank-shaft, provided with a roller sleeve, a lever adjustably mounted
on said crank-shaft, and provided at its inner end with a ball valve, in combination
with eduction valve and float, substantially, as and for the purpose set forth.
4. A water closet tank having a flushing apparatus, a connection between the
seat and the operative parts, whereby while the seat is depressed, the tank will be
intermittently flushed, and an after-flush operated to flush the closet when pressure
is removed from the seat, subsantially as and for the purpose set forth.
