I, HERMANN BECKMANN, of 6, Karlstrasse, Magdeburg, in the German Empire,
Enginéer, 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:-
My invention relates to a new or improved apparatus for straining and
clarifying oils, and has for its object to effect such straining and clarifying more
quickly and effectually, and to automatically remove the oil as fast as treated
and convey the same to a storage chamber beneath the apparatus.
Referring to the accompanying drawings (which illustrates a central vertical
section of my invention). In carrying my invention into effect, I construct of
metal or other suitable material or combination of materials a circular or rect-
angular vessel such as A, provided at its upper end with an inlet chamber or
hopper B, and at its lower end with an outlet passage C.
At a suitable distance above the bottom of A is placed and fixed a frame or
stand D preferably in the shape of a cross, the four members of which serve to
support a metallic porcelaine or other vessel E, having a perforated or sieve
like bottom F, covered with a layer or layers F¹ of any suitable material adapted
to form a filtering medium, this being then covered by a perforated or sieve likė
plate G.
Below the hopper or inlet B, and occupying the entire width of the space
between the vessels A and E, is placed and fixed an annular filtering plate H,
supported upon a ridge or its equivalent h, while within the vessel E, and one
within the other, is placed any number of circular or other shaped pots or vessels
of metal, porcelaine, stoneware, glass or other material, preferably three, and
indicated by J, K and L respectively, the walls of all of which are perforated, and
cach surrounded externally by a coating a of any suitable material adapted to
form a filtering or straining medium.
From the innermost and smallest of the said pots or vessels (L) is lead a
siphon M, the lower and outer end of which is governed by a tap or cock m
and extends into the mouth of a reservoir N, arranged to form a support for
the vessel A, and provided with an outlet or draw-off passage 0. The manner
of operation is as follows.
The dirty or uncleansed oil would be poured into the inlet or hopper B, and
by percolating through the straining surface H would trinkle down inside the
wall of A, and outside the wall of E, into the lower end of the chamber A, whence
it would ascend through the perforated surface 1', filtering medium F¹ and per-
forated surface G. and rising in the vessel E would successively filter through
the vessels J, K I. into the latter, when, by starting the siphon M, the contents
of L would be thereby conveyed into the reservoir N, until removed therefrom
by the passage 0.
The outlet passage C in the vessel A serves for removing the dirt or sediment
that may accumulate in the bottom of the said vessel.

page_text: 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) The herein described apparatus for filtering and clarifying oils, substan-
tially as set forth and shewn by the appended drawing.
(2) The improyed apparatus for filtering and clarifying oils, the combination
of an outer vessel A and inner vessel E, the former having an inlet or hopper B
and outlet C, and connected to the latter by a straining surface H, the said inner
chamber being supported upon a frame such as D), and provided with perforated
bottom F, filtering medium and perforated plate G, the latter supporting two
or more vessels such as J, K and L placed one within the other, and each having
perforations in its walls surround by a straining surface a, with siphon such
as M for conveying the oil as clarified from the vessel Lto a reservoir N, the
latter serving as a support for the vessel A and its contents, substantially as
herein described and shewn by the accompanying drawing.
Dated this 3rd day of March 1899.
