We CARL HEINRICH ROECKNER, FRANK LIONEL ROECKNER, RAMSEY LLEWELLYN
ROECKNER of No. 8 Tynemouth Place, Tynemouth in the County of Northumberland
Paper Makers, and Contractors 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 :—
Our Invention is intended for the purpose of utilizing or disposing of Sewage,
Manufacturing Waste Water, and such like liquids, and for the purpose of drawing
clear water from a river, and consist in-
1stly. Improvements on the Siphon Clarifier as patented in No. 5591, A.D. 1881,
by fixing on, or near the top of the Siphon, levelled overflow brackets, forming a
channel connected with the overflow pipe, into this channel the liquid evenly flows,
so as to prevent a direct current of liquid, which would occur throughout the whole
of the siphon, if the overflow pipe took its supply from any particular point out of the
level of the liquid.
2ndly. Improvements by placing Siphons, Inverted Siphons or Cells, in a diagonal
position, at such a degree, that the lower side acts as a guide, so that the specific
gravity of the settling substances is able to overcome adhesion, & the sediment slides
down to the bottom of the siphon or cell, to make room for the further precipitating
solids, and to enable the clarified liquids to pass undisturbed.
3rdly. By constructing in the siphons or cells, diagonal partitions, corrugated, or
plain, at such a degree, that they act as guides, for the same purpose as mentioned
before.
4thly. By fixing at the bottom of these siphons or cells, suitable filters, so that
the settling substances are by filtration, obtained in a portable form, the filtration
being forced through the height of the liquid above.
5thly. By fixing on the top of the siphons or cells, filtering bags hanging diagonally,
or diagonal partitions of filtering cloth, in such a manner that the rising liquid has to
pass up through them, so that when the light sediment adhering to the side of the
cloth, attains a certain thickness, it will through specific gravity fall or slide down
these bags, or partitions, thereby, preventing the cloth from becoming choked.
The foregoing description explains the general nature of our said Invention, but in
order that the same, & modification thereof, which comes within its scope, may be
clearly understood, we refer to the annexed drawings
'-
Fig. 1 shows a resevoir B, which receives the Sewage, waste water, or other liquids

page_text: to be clarified, through C, into this resevoir the Siphon A dips, which when it has
its air exhausted through vacuum pipe V, will be, filled with the liquid flowing
into B, & being thus suspended over the liquid in B, admits of the heavier substances
falling to the bottom of B, while the clear liquid is discharged through pipe D,
which in connection with A forms the Siphon. On the top of A are fixed brackets b,
over which the liquid evenly flows before entering D, thus preventing a separate
current through A, which would occur if D discharged the liquid independent of
brackets -h is a pipe for drawing off air which may accumulate during operation,
it is a thin pipe dipping into discharge D, rising to top of A, & dipping down again
into the liquid the upper bend has a small hole I-When the siphon is in action,
there will be a continual flow through h, and should air accumulate in A, it will be
drawn off through hole I, & he discharged in small bubbles into D & follow the
current.
If the Clarifier be used for drawing water from a river, A would dip into the river
instead of into B, so that the settling mud falls back into the river & is carried
away by the current of the river.
Fig. II shows the siphon in a diagonal position, to which the liquid may be supplied
in the usual manner, or through the overflow of an inverted siphon or cell G, as
shown in fig. III, having at the same time a filter F, at the bottom.
Fig. III shows an inverted siphon G, which may be formed by a tube, or cylinder,
or may be a cell with one or more partitions p, p, p, as seen in fig. IV, which
partitions would be best corrugated as shown in fig. IV (a plan of fig. IV).
may
Figs. 11, 1V and V show the filter F, for solidifying the sediment, which
contain a single filter bag, held in position by perforated iron plates, or a Polypus, or
other press, which can when charged be changed by closing cock K, & can also be
applied to each apparatus.
Figs. V, VI & VII illustrate the filter bags m, m², m", which are kept in position
by float balls /// etc, & weights W, W, W.
These bags are for securing perfect clarification, & may be applied to an ordinary
siphon clarifier, as in fig. V, & in a similar manner on the outflow of an inverteil
siphon or cell figs. II, III & IV illustrated in figs. VI & VII, fig. VII being an end
view of fig. VI sectionally.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim is :
Firstly. For the purposes before named, the use & application of siphons with
levelled overflow brackets, and air exhaust pipe.
Secondly. For the purposes before named the use & application of siphons inverted
siphons, or cells placed in a diagonal position, so that lower side of same acts as a
sediment guide.
Thirdly. For the purposes before named, the use & application of diagonal sediment
guides in siphons or cells.
Fourthly. For the purposes before named, the use & application of filters or filter
presses on the bottom of siphons, inverted siphons, or cells, to solidify the mud or
other sediment.
Fifthly. For the purposes before named, the use & application of hanging down
filter bags, through which the liquid has to pass upwards, leaving the sediment on the
other side, to fall down after acquiring sufficient specific gravity.
