COMPLETE SPECIFICATION.
Improvements in Flushing Apparatus.
I, ABRAM NATHANIEL PASMAN, of 62, Boyd Avenue, Jersey City, State of New
Jersey, U.S.A., Plumber, 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:
This invention relates to an improvement in flushing apparatus, and the object
thereof is to provide simple and effective means for flushing water-closet bowls
of any desired type effectively and noiselessly, a device which cannot get out of
order and which will not deteriorate when it becomes old.
The invention will be hereinafter fully described and specifically set forth in
the annexed claims.
In the accompanying drawings:
Figure 1 is a side elevation of the device, partly sectional; and
Figure 2 is an enlarged section showing a slight modification in the valve
portion of the apparatus.
In the practice of my invention, I employ an elongated metallic tank 1 which
is secured preferably to the wall by means of the brackets 22, but it is obvious
that it may be supported from the floor by means of a suitable standard if
preferred.
The upper end of the tank 1 has a hole 3 centrally located therein and in
this hole is secured the neck 5 of a secondary tank 6 of any desired form. This
secondary tank 6 is divided by means of a partition 7 into an upper and lower
chamber. A hole 8 centrally located in the partition 7 is adapted to be closed
by means of a buoyant globe 9 which normally rests upon the pin 10 secured
in the neck 5.
The neck 5 is of sufficient diameter to permit of the passage of air downwardly
therethrough when the globe 9 rests upon the pin.
A pipe 11 communicating with the upper chamber 12 is preferably bent down-
wardly and telescopes into the upper end of the overflow pipe 13, the object of
the telescopic connection being to permit air to enter the upper end of the
overflow pipe 13 and pass through the pipe 11 into the chamber 12 and thence
into the tank 1 during the flushing operation and at the same time to prevent
water from overflowing the upper end of the overflow pipe 13.
The lower end of the tank 1 is open and at a point near the lower end thereof
and within the tank an annular conical flange 15 is fixed thereto or if preferred,
may be formed integrally therewith.
A washer 16 of any material suitable for the purpose is adapted to contact
with the lower edge of the conical flange, said washer forming a seat for the
buoyant globe 17. This globe may be constructed of metal and hollow or may
be made of any approved buoyant material and solid.
A cylindrical chamber 18 is adapted to be connected with the lower end of
the tank 1 preferably by being telescoped within said lower end and fastened
thereto, but it is obvious that it may be threaded therein or secured thereto by
means of flanged couplings. The upper end of this chamber is provided with

page_text: an annular ring 19, preferably formed integrally therewith, said ring being
adapted to contact with and hold securely in position the washer 16.
From the inner periphery of this ring are depended a series of guide bars 20 20,
preferably formed integrally with said ring, the whole being a metallic casting
and the number of these guide bars being preferably four.
A piston 21 is adapted to slide within these guide bars. A connecting rod 22
pivotally connected with said piston is also pivotally connected with a crank 23
fixed upon the crank shaft 24 which passes through suitable openings in the
sides of the chamber 18. The outer end of this crank shaft 24 is bent approxi-
mately at right angles to the axis of said shaft, the free end thereof forming the
handle 25.
The lower end of the chamber 18 is contracted, terminating in the flush
pipe 26 which is provided with an elbow 27 connected in any approved manner
to the bowl 28.
The lower end of the overflow pipe 13 is provided with an elbow 29 which
communicates with the chamber 18.
A supply pipe 30 is adapted to bring the water from any convenient position
and convey it to the interior of the tank 1 by means of the opening 31 in the
wall of said tank at a point a little above the conical flange near the bottom
thereof.
These pipe connections may be made in any manner preferred.
In the operation of the device, the piston normally occupies the position
shown in Figures 1 and 3. The globe 17 rests upon its seat upon the washer 16
and the globe 9 rests upon the pin 10. Water flows through the supply pipe
into the tank 1, the globe 17 being held upon its seat by the water pressure
above it. The water rises within the tank until it reaches the top thereof when
the globe 9 will float into position in the hole 8 of the partition 7 closing the
passage and preventing the inflow of any more water.
When it is desired to flush the bowl, the handle 25 is raised to the position
shown in dotted lines in Fig. 3. This causes the piston to slide upwardly between
the guide bars and raise the globe 17 to the position shown in dotted lines. Water
instantly flows from the tank into the chamber 18 and the globe 17 floats to
the top of the tank. As soon as the ball has started, the handle is released and
falls back to its normal position as indicated by full lines. The water flows
downwardly through the chamber 18 and flush pipe 26 into the bowl.
As soon
as water begins to lower in the tank, the globe 9 falls from its seat in the
partition 7 and permits a passage of air from the pipe 11 into the tank 1..
As the water recedes in the tank, the globe 17 falls with it and when all the
water in the tank has passed out through the flush pipe, the globe 17 again seats
itself upon the washer 16 and the water coming through the supply 'pipe again
fills the tank. This operation will be repeated as often as the handle 25 is raised.
The overflow pipe 13 is ordinarily without function, the only object of its
use being to prevent the overflow of water in case dirt or other matter coming
through the supply pipe prevents the globe 9 from properly seating itself in
the partition 7, thereby cutting off the water supply.
It is obvious that any other form of globe starting device may be used in
place of that shown which is at this time preferred.
The overflow pipe 13 may be dispensed with entirely if preferred, and the
secondary rank 6 may also be dispensed with and a floatable valve 'located within
the tank 1 may be substituted therefor if preferred.

In Figure 2 I have shown a slight modification in the valve attached to the
lower end of the apparatus. The lower end of the tank is formed without the
conical flange 15 so that the cylindrical chamber 18 may be attached in the manner
shown in Figure 2.
A partition provided with openings 34, 34 and 34' separates the tank from
the chamber 18. The buoyant globe 17 rests upon the washer 35 in the
opening 341.

page_text: Extending from the piston 21 are the arms 36 which carry the two balls 37,
said balls 37 normally resting upon washers in the openings 34. The arms 20
may be braced by the braces 20.
In the operation of this valve the balls 37 are raised out of the openings 34
when the piston is forced up thereby allowing water to immediately enter the
chamber 18, and insures the passage of some water into the bowl 28 in case the
operator does not raise the handle 25 far enough to start the globe 17 upward.
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:-
