Improvements in Oil Purifiers.
I, FRANZ TREU, of 7, Krausnickstrasse, Berlin, Germany, Inventor, do hereby
declare the nature of this invention and in what manner the same 18 to be
performed, to be particularly described and ascertained in and by the following
statement:
The present invention relates to an apparatus for purifying oil and especially
waste machine oil
The accompanying drawing shows a sectional vertical elevation of the purifier.
The apparatus consists of an oblong, rectangular closed receptacle a, which
is provided at one end with the upward extension b, open at the top. Within this
extension a strainer or sieve c is arranged A partition wall d extends from the top
of the receptacle downwards to about three fourths of the depth of the receptacle,
thus leaving a passage between its lower edge and the bottom of the receptacle
A second partition wall extends from the bottom of the receptacle upwards to
about three fourths of the height of the receptacle, thus leaving a passage between
its upper edge and the top of the receptacle The receptacle a consequently 18
divided off into three compartments A, B, C, the capacity of the latter of which
preferably is about the same as of the other two combined The dimensions
however may vary according to requirements without in any way affecting the
invention
Near the upper edge of the partition wall f an angularly projecting strip of wire
gauze or sieve g 18 arranged
Drawing-off cocks h, are provided in the wall of the receptacle a; the cock h
being arranged below the partition wall d and the cock at about the middle of
the compartment C The situation of these cocks however can be varied from that
shown in the drawing
Before operation, cotton waste 01 some other filtering medium 18 placed into
the compartments A & B The oil to be purified is poured into the extension b,
passes through the sieve c which retains the coarser impurities, and trickles upon
the cotton waste After thoroughly having soaked the cotton waste within the
compartment A, the oil gradually takes its course up the cotton waste in the
compartment B and trickles over the edge of the partition wall f. The sieve g
serves to retain any particles of cotton waste, which may fall over the partition
wall f
By operating the cock the purified oil may be drawn off The cock is
only employed for occasionally drawing off the water, which in purifying rather
hydrous oil, will settle at the bottom of the compartments A & B by reason of its
specific gravity
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:
-
In an oil purifier the combination of the closed receptacle a, the exten-
ainn hanan at the tan and the grave within the said extengran a partition wall ?

between its lower edge and the bottom of the receptacle, a partition wall f
extending from the bottom of the said receptacle upwards and leaving a passage
between its upper edge and the top of the said receptacle and a cock for drawing-
off the purified oil, as and for the purpose set forth
2. In an oil purifier the combination of the closed receptacle a, the exten-
81on b open at the top and a sieve c within the said extension, a partition wall d
extending from the top of the said receptacle downwards and leaving a passage
between its lower edge and the bottom of the said receptacle, a partition wall
extending from the bottom of the said receptacle upwards and leaving a passage
between its upper edge and the top of the said receptacle, a sieve g arranged below
the upper edge of the said partition wall and projecting angularly into the
compartment C and a cock for drawing-off the purifled oil, substantially as
described.
3:In an oil purifier the combination of the closed receptacle a, the exten-
Blon b open at the top, a sieve within the said extension, a partition wall d
extending from the top of the said receptacle downwards and leaving a passage
between its lower edge and the bottom of the said receptacle, a partition wall f
extending from the bottom of the said receptacle upwards and leaving a passage
between its upper edge and the top of the said receptacle, a sieve g arranged below
the upper edge of the said partition wall and projecting angularly into the
compartment C, a cock for drawing-off the purified oil and a cock h for drawing-
off the water, substantially as and for the purpose set forth.
