“IMPROVEMENTS IN APPARATUS FOR CLEANSING AND SEPARATING IMPURITIES
FROM MACHINERY OIL AND GREASE AND FOR RECOVERING OIL FROM CLEANSING
"
WASTE AND OTHER SIMILAR MATERIAL communicated to me from abroad by
A. Koellner of Neumueblen in the Empire of Germany
This invention has for its object an arrangement of apparatus for the cleansing
and separating of impurities from oil and grease which has been already used
for lubricating cooling and other purposes and which has been gathered from the
bearings drippers and other parts of machinery or from cutting metals as well as
from waste and other cleansing clothes or material used for cleaning the greasy
parts of machinery so that the oil or grease may be used over again thus effecting a
very great saving in such materials.
In carrying out the invention a casing is constructed preferably of iron which
casing is divided into compartments the top compartment being arranged to receive
the dirty oil or grease upon a perforated bottom which stops the grosser impurities
passing through. Beneath this grating is a compartment heated by means of a
steam pipe passing through and fitted at the bottom with a well or depression

the oil or grease and cause it to flow freely down. The upper part of one side of
this compartment is further arranged to communicate through another perforated
bottom with a third compartment filled with twisted cotton or other filtering
substance which is capable of being pressed to any degree of closeness by means of
a perforated plate pressed down by suitable screws. Having floated upon the
surface of the oil or water and overflown through the filtering medium the partialy
clean oil flows into a fourth compartment similarly filled and fitted to the last
mentioned one and from whence it finally falls into a fifth compartment fitted with
a draw off cock and which forms the receptacle for the clean oil or grease.

JULIUS DAVIDS of the City of Manchester in the County of Lancaster
"IMPROVEMENTS IN APPARATUS FOR CLEANSING AND SEPARATING IMPURITIES
FROM MACHINERY OIL AND GREASE AND FOR RECOVERING OIL FROM CLEANSING'
WASTE AND OTHER SIMILAR MATERIAL a communication from abroad by
A. Koellner, of Newmuehlen, in the Empire of Germany.
"
This invention has for its object an arrangement of apparatus for the cleansing
and separating of impurities from oil and grease which has been already used
for lubricating, cooling and other purposes and which has been gathered from the
bearings drippers and other parts of machinery or from cutting metals as well as
from waste and other cleansing cloths or material used for cleaning the greasy
parts of machinery so that the oil or grease may be cleaned and used over again
several times thus effecting a very great saving in such materials.
And in order that the said invention may be the more readily understood and
carried into practical effect I have hereunto annexed a drawing illustrative of the
improvements and will now proceed to describe the same with the assistance of the
Figures and letters of reference marked thereon.
Fig 1 is a front sectional view of the improved apparatus heated by a steam
jacket and Fig 2 is a sectional plan of Fig 1 taken on the line A-B, Fig 3 is a
front sectional view of a similar apparatus heated by a steam pipe and Fig 4 is an
end sectional view of Fig 3 taken upon the line C-D-Fig. 5 is a front view of a
suitable stand for supporting the apparatus at a convenient height from the floor.
In carrying out the invention a casing a is constructed preferably of cast iron
which casing is divided into compartments the top compartment or hopper b being
arranged to receive the dirty oil or grease upon a perforated bottom c which stops
the passage of waste wool or other grosser impurities which have accidentally
become mixed with the dirty oil or grease and thus prevent the same entering the
cleansing chamber. Beneath this grating is a compartment d heated by means of a
steam jacket e as in Figs 1 and 3 or by a steam pipe e passing through as in Figs 3
and 4 and fitted at the bottom, with a well or depression f leading to a stop cock g.
By means of the heating apparatus e the machinery oil or grease with which the
apparatus has been filled is warmed into a thin fluid and can thus easily separate
itself from the water dirt or other impurities which fall to the bottom.
Into the warming or heating apparatus e steam is introduced through the cock e¹
and which goes off through the cock e². Instead of steam it will be apparent that
hot water or hot air may be substituted. The upper part of one side of this com-
partment is further arranged to communicate through another perforated bottom h
with a third compartment i filled with twiste cotton or other filtering substance
which is capable of being pressed to any degree of closeness by means of a perforated
plate; pressed down by suitable screws k.
The liquid oil or grease having pushed itself slowly (following the law of liquids
to find their own level) through the compartment i then overflows in a partially
cleansed state into a fourth compartment 7 similarly filled and fitted to the last
mentioned one and from whence it finally falls into a fifth compartment m fitted
with a draw off cock n and which forms the receptacle or store for the clean oil or
grease. Instead of filling the boxes i and with cotton twist they may be filled
with saw-dust, wool, moss, cloth, textile-fabric, lime, sand-bags or other suitable
material.

page_text: It will be observed that the division plate separating the chambers i and is
turned over at its top edge as illustrated and that a thin angled or bent plate O is
used to partially cover the perforated plate covering the compartment these are
designed to lead the liquid oil or grease towards the centre of the compartment
and thus ensure their passing directly through the filtering material.
The air pipe p serves to allow of the inlet and outlet of air to and from the
chamber m. The dirt which has gathered in the chamber d can be let out through
the cock g from time to time.
Although two chambers are shewn filled with filtering material it will be
apparent that only one of such chambers may be used for instance the chamber i or
chamber can be dispensed with or more than two of such filtering chambers
could be employed.
A modification of the same invention could also be used without the heating
apparatus and the heat be obtained by placing the apparatus upon a stove or other
heating medium or in a room heated to the desired temperature.
For use on ship-board the chambers would be enclosed or provided with suitable
covers.
Having thus particularly described and ascertained the nature of the said
invention so communicated to me from abroad as aforesaid I wish it to be distinctly
understood that I do not confine myself to the precise details, relative proportions
or dimensions of the improved apparatus hereinbefore described and illustrated
on the accompanying drawings as the same may be considerably varied without
departing from the invention but what I desire to claim is apparatus for cleansing
dirty oil and grease and rendering the same fit for re-use is:-
1 The hopper b and chamber d which is a receiver and settlement chamber
for the dirty oil or grease substantially as and for the purposes hereinbefore
described.
2nd The application of warming or heating apparatus by means of which the
grease or oil may be kept in a thin liquid state as and for the purpose
described.
3rd The perforated filtering chambers i and 1 so arranged in the apparatus that
the oil or grease bas to pass from bottom to top and then from top to bottom
self-actingly or as hereinbefore described.
4th The chamber m in which the clean grease or oily material will gather and
from whence it can be taken at convenience for re-use as described.
5th The adjustable screws k whereby the filtering material in the perforated
boxes can be tightened or loosened as required.
6th The air pipe p for permitting the free access and egress of air to and from the
chamber m.
In witness whereof I the said Julius Davids have hereunto set my hand and
seal this 4th day of April in the year of our Lord One thousand eight hundred and
eighty four.
