COMPLETE SPECIFICATION.
Siphon Discharge Pipes.
I, WALLACE HENRY BATE of Belmont, in the County of Middlesex and
ommonwealth of Massachusetts, United States of America, Manufacturer, do
ereby declare the nature of this invention and in what manner the same is to
e performed, to be particularly described and ascertained in and by the following
atement:-
My invention relates to apparatus for discharging fluids from tanks and similar
essels by means of a siphon, and has for its object the production of a device
which shall be much cheaper and more simple than any now in use by dispensing
with all valves and other starting devices which have heretofore been necessary,
thereby producing an apparatus of greater durability and more constant efficiency.
My invention is particularly useful in tanks for flushing water closets, but may be
used for many other purposes.
I accomplished the above object by the device shown in the accompanying
drawing, in which

invention.

Figure 4 is a sectional view of a tank containing a modified form of my
invention.
Like numerals refer to like parts in all the figures.

Referring to the drawing, 1 is a tank adapted to contain fluid, the normal level
of said fluid being maintained at about the position indicated by the dotted line 7,
by means of any of the well known devices used for such purpose, as for example,
by a valve in the supply pipe which is controlled by a float. 2 is the outlet of
discharge pipe which is here shown as placed in one side or end of the tank.

connected to the pipe 2, the other end being connected to the bent pipe 5.
lever pivotally supported on or near the tank, said lever having at one end a
weight, 10, sufficiently heavy to keep the pipe 5 normally raised from the bottom
0 of the tank, in about the position shown in the drawing. 11 is a wire or rod
connecting the pipe 5 with the lever 9, and 12 is the cord or chain by which the
device is operated. 14 is a small tube which is screwed into the upper part of the
pipe 5, and bent downwardly so as to be about the same length as the said pipe.
The position of the various parts of the device should be so adjusted in relation
35 to each other, that a portion of the bent pipe 5 shall be a little above the normal
level of the fluid in the tank, while the outlet shall be a little below the normal
level.
The operation of my invention is as follows:

page_text: inlet of this tube air will be admitted to the upper part of the bent pipe 5, and the
siphon will thus be broken.
The pipe 4 being flexible, easily accommodates itself to the movement of the pipe 5,
but instead of using a flexible pipe in this place, I may use a metal pipe, connected
to the discharge pipe at 3 by means of any of the well known movable joints, two
of which are shown in Figs. 2 and 3.
Instead of placing the discharge pipe in the side or end of the tank, I may place
it in the bottom of the tank, as shown by the dotted lines 13.
A modified form of my invention is shewn in Fig. 4. In this case the inlet of
the siphon is held in a fixed position near the bottom of the tank. The pipe being
flexible, the part which is normally above the level of the fluid is depressed by
means of a rod connected to the lever, substantially as hereinbefore described.
Another application to which my invention is available is for periodically
discharging the fluid from the tank, in which case the means for lowering and
raising the pipe would not be used; but the inlet of the pipe would be fixed near
the bottom of the tank. If fluid were to be continually admitted to the tank, as
soon as the level of the fluid reaches the top of the pipe, the pipe would act as
a siphon, and discharge the tank. In this case the supply pipe should be smaller
than the siphon.
By dispensing with all valves, I greatly cheapen and simplify the apparatus, and
prevent all leakage which always results from the use of valves as soon as they
become worn.
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. The combination, substantially as, and for the purpose set forth, of a tank ;
an outlet in said tank below the level of the fluid in the same; a siphon pipe
attached by one end to said outlet, the upper portion of said pipe being normally
held above the normal level of said fluid and adapted to be lowered and raised
in said fluid; an inlet for said pipe below the normal level of said fluid; an air
inlet in said pipe extending below the level of said fluid, and means for lowering
and raising the upper portion of said pipe.
2. The combination, substantially as, and for the purpose set forth, of a tank
or receptacle; an outlet in the same; a siphon pipe movably connected by one end
to said outlet and means for depressing the upper portion of said pipe below the
normal level of the fluid in the tank.
3. The combination, substantially as, and for the purpose set forth, of the
tank 1; the outlet 2; the movable pipe 4; attached to the outlet; the curved
pipe 5, attached to the pipe 4; the air inlet 14; the pivoted arm 9; the rod 11;
weight 10 and cord or chain 12.
4. In a tank adapted to receive and discharge fluids, the combination of the
pipe 2 movable pipe 4 and bent pipe 5, substantially as shown and for the
purpose specified.
