St. Petersburg, aforesaid, Gentlemen, do hereby declare the nature of this invention:
to be as follows:-
This invention relates to syphons and has for its object to enable large quantities
of liquid to be readily emptied however small be the quantity of effluent liquid.
It is well known that syphons as hitherto made will act and produce suction only
in the case of the whole inner section being filled with liquid; otherwise, that is,
if the quantity of the effluent liquid be insufficient to fill the syphon, the liquid.
will only pass over the bend of the syphon without producing suction.
In the new syphon, according to this invention, this defect is obviated by the
combination of two or more syphons of decreasing diameter constructed and
combined in such a manner that the suction ends of all the component syphons
are separate and are sunk to the same, or to different depths in the liquid to be
emptied, the undersides of the bends are on the same level or practically so and
the discharge ends of the syphons are all connected together so that the com-
ponent syphon of smaller or smallest diameter discharges the liquid into the
component syphon of larger or of next larger diameter, this latter discharges its
liquid in the following syphon of still larger diameter and so on where more
than two component syphons are used. By thus discharing the contents of one
component syphon into the other or others the following advantages are obtained,
viz.as the passage through the component syphon of smallest diameter is very,
small it will be filled with liquid and act with but a small quantity of effluent
liquid and by discharging its contents in the syphon of next larger diameter it
produces in this latter a partial vacuum, in consequence of which this latter
syphon sucks the liquid and thus becomes filled with it. Where more than two
component syphons are used the latter syphon discharges the liquid into the next
larger syphon and produces a partial vacuum in it also so that this larger syphon
begins to suck the liquid and so on. By this combination of syphons a very small
quantity of the effluent liquid will be sufficient to empty a large volume of it
through a compound syphon of large resultant capacity.

page_text: 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 syphons and has for its object to enable large quantities
of liquid to be readily emptied however small he the quantity of effluent liquid.
It is well known that syphons as hitherto made will act and produce suction
only in the case of the whole inner section being filled with liquid; otherwise, that
is, if the quantity of the effluent liquid be insufficient to fill the syphon, the liquid
will only pass over the bend of the syphon without producing suction.
In the new syphon, according to this invention, this defect is obviated by the
combination of two or more syphons of decreasing diameter constructed and
combined in such a manner that the suction ends of all the component syphons are
separate, the undersides of the bends are on the same level or practically so, and
the suction ends may be on the same level or practically so that is in or about
the same horizontal plane or they may be in an inclined plane. The discharge ends
of the syphons are all connected together so that the component syphon of smaller
or smallest diameter discharges the liquid into the component syphon of larger or
of next larger diameter, this latter discharges its liquid in the following syphon of
still larger diameter, and so on, where more than two component syphons are used.
By thus discharging the contents of one component syphon into the other or others
the following advantages are obtained, viz.: as the passage through the component
syphon of smallest diameter is very small, it will be filled with liquid and act with
Eut a small quantity of the effluent liquid and by discharging its contents in the
syphon of next larger diameter it produces in this latter a partial vacuum, in
consequence of which this latter syphon sucks the liquid and thus becomes filled
with it. Where more than two component syphons are used, the latter syphon.
discharges the liquid into the next larger syphon, and produces a partial vacuum in
it also, so that this larger syphon begins to suck the liquid, and so on.
combination of syphons a very small quantity of the effluent liquid will be sufficient.
to empty a large volume of it through a compound syphon of large resultant
capacity.
By this
In order that this invention may be well understood, we have illustrated in the
accompanying drawings, an application of the combination of six syphons arranged
in the manner herein before described and designed to periodically empty large
quantities of liquid. Figure 1 is a longitudinal vertical section and Figure 2 a
cross section on the line 1-2 Figure 1.
A is a reservoir (for instance a sewage pit) from which a liquid is to be
discharged as soon as its level attains a predetermined height (indicated at ab);
B is a tube by which liquid is discharged into the reservoin A in quantities which
may be very small at certain times. C is a partition in the reservoir, for retaining
solid sediments away from the compartment in which the syphons are arranged.
D is a screen or grate in this latter compartment for protecting the syphons from
dirt or the like. E is a system of syphons with independent suction openings and
gradually decreasing in diameter and arranged to dischargo the liquid from each
syphon in the next larger one.
The undersides of the bends of the several component syphons may be on the
.same level as shewn in Figure 2 and the inlets or suction ends may be on the same
level as in Figure 1 or they may be arranged in an inclined manner
Figure 3.
as in
It is obvious that as soon as the liquid in the reservoir A attains the level ab
the component syphon el will be put into action by a very small quantity of the
effluent liquid and in discharging the liquid into the next component syphon e², a
partial vacuum will be thus produced therein which compels this syphon e² to suck
the liquid in its turn and so on with regard to the component syphons e e e and e.
In this manner the whole system of syphons will be brought into action by a
quantity of liquid sufficient only to start into action the component syphon,e of
smallest diameter. It will be understood as before stated that two or more
component syphons can be used.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
The combination of two or more component syphons of decreasing diameter
arranged in such a manner that the smaller or each smaller component syphon
lischarges its contents into the larger or next larger component syphon, the suction
openings of all the syphons being independent from each other, and the lower sides
of the bends being on the same level or practically so, substantially as and for the
purpose herein before described.
