I, HENRY HARRIS LAKE, of the firm of Haseltine Lake, and Co Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the naturo
of my invention for AN IMPROVED METHOD OR PROCESS OF AND APPARATUS FOR
RECOVERING PARAFFINE, STEARINE OR SIMILAR WAX LIKE SUBSTANCES FROM
PETROLEUM OR OTHER OIL" to be as follows:-
This invention relates chiefly to the process of recovering paraffine, stearine, or
other solid matters from petroleum and oils, and to apparatus therefor.
The improved process consists in spraying oils containing paraffine, stearine, or
other wax-like substance upon a travelling porous apron in a cold room, so as to
chill and precipitate the solids upon the moving belt, then pressing the belt
between press rolls to remove the remaining liquid, and then scraping off the
solids and collecting the liquids separated from the solids as hereinafter fully
described.
The improved apparatus comprises an endless blanket or belt of textile material
travelling over a series of roller's so arranged that the blanket passes over rollers at
each end, and between rollers which are closely pressed together. Over this endless
belt is an arrangement or device for spraying the oil. This device may consist of a
pipe at right angles to the belt and at some distance above it, say from ten to
twenty feet, the said pipe being provided with a number of pet-cocks with small
apertures through which the oil is forced, falling in a spray upon the blanket or
belt.
Bearing upon the upper pressing rollers is a scraper to remove the paraffine or
stearine which adheres to the roller; and beneath, or at one side of the lower
pressing roller, is a small trough to collect the oil. Partially under both rollers is
an endless belt travelling at right angles with the principal belt and intended to
catch the material removed by the scraper.

The machine is placed in a room kept cool, and the oil is brought to the machine
previously chilled or not as inay be found desirable; it is thrown upon the travelling
blanket in a finely divided spray, or atomized condition, in which state it quickly
assumes the temperature of the room. The oil is then carried by the belt between
the pressing rollers, where the wax, paraffine, stearine or other solid material is
separated from the oil, and adheres to the upper roller, being removed therefrom
by a suitable scraper and falling upon a travelling belt by which it is carried
away; the oil penetrates the endless blanket and trickling down the lower
pressing roller, is collected in the trougli placed underneath, or at one side, of the
roller.
In carrying the said invention into practice I provide a suitable frame in which
are mounted a pair of pressing rollers and two idle rollers. Over the. sáid idle
rollers and the lower pressing rollers passes an endless blanket.
A suitable pipe having cocks is provided for ejecting oil onto the blanket.
The machine is placed in a room, the temperature of which is kept at the degree
at.which it is desired to press the oil; this temperature will vary according to the
nature, of the oil operated upon.
The operation of the machine is as follows, that is to say, the oil to be pressed
having been chilled to the proper temperature (and this chilling is a very important
part of the operation,) is thrown in fine sprays upon the endless belt or blanket as
evenly, as is practicable, the said endless belt being in motion.
+
One of the idler rollers. is placed slightly over, and, quite near to, the upper
pressing roller but not so as to come into contact with it, the object being to keep
the blanket closely pressed against a considerable portion of the circumference of
the latter roller, thus materially assisting in the separation.
The blanket then passes between the pressing rollers, which latter rollers are
pressed together, more, or less closely, according to the kind of oil to be pressed.
The paraffine or stearine adheres to the upper pressing roller and is scraped off by
a chisel-shaped scraper falling upon an endless belt by which it is carried to any
convenient place of deposit, either inside or outside the pressing room...
The oil separated from the solid material passes through the belt, and trickling
down the lower pressing roller is caught by a trough and carried into a receptacle
provided for it at the end of the said roller.
The oil to be operated upon and containing the paraffine, stearine, etc, instead of
being chilled to the desired temperature, before, being sprayed, may be sprayed at
its natural temperature at a sufficient height, so that by its fall and travel, it
..becomes sufficiently distributed to quickly assume the temperature of the sur-
rounding atmosphere and reach the pressing rollers at the proper temperature.
The endless: belt or, blanket may be composed of felt, cotton duck, muslin, hair
cloth, or anya suitable, porous material that will allow the oil separated from the
paratline, wax, or stearine, free passage through it..
I find in practice a loose cotton cloth to work satisfactorily and at less cost than
any other, suitable material.

hard metal, 1

slightly upwards. Any other suitable device for producing a spray may be used.

Southampton, Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "AN IMPROVED METHOD OR PROCESS OF, AND APPARATUS
FOR, RECOVERING PARAFFINE, STEARINE, OR SIMILAR WAX-LIKE SUBSTANCES FROM
PETROLEUM OR OTHER OIL" 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 the process of recovering paraffine, stearinc, or other
solid matters from petroleum and oils, and to apparatus therefor.
The improved process consists in spraying oils containing paraffine, stearine, or
other wax-like substances upon a travelling porous apron in a cold room, so as to
chill and precipitate the solids upon the moving belt, then pressing the belt
between press rolls to remove the remaining liquid, and then scraping off the
solids and collecting the liquids separated from the solids, as hereinafter fully
described.
The improved apparatus comprises and endless blanket or belt of textile material
travelling over a series of rollers so arranged that the blanket passes over rollers at
cach end, and between rollers which are closely pressed together. Over this
endless belt is an arrangement or device for spraying the oil. This device may
consist of a pipe at right angles to the belt and at some distance above it, say from
ten to twenty feet, the said pipe being provided with a number of pet-cocks with
small apertures through which the oil is forced, falling in a spray upon the blanket
or belt.
Bearing upon the upper of the pressing rollers is a scraper to remove the
paraffine or stearine which adheres to the roller; and beneath, or at one side of
the lower pressing roller, is a small trough to collect the oil. Partially under both
rollers is an endless belt travelling at right angles to the principal belt and intended
to catch the material removed by the scraper.
i
The machine is placed in a room kept cool, and the oil is brought to the machine
previously chilled or not as may be found desirable; it is thrown upon the
travelling blanket in a finely divided spray, or atomized condition, in which state
it quickly assumes the temperature of the room. The oil is then carried by the
belt between the pressing rollers, where the wax, paraffine, stearine or other solid
material is separated from the oil and adheres to the upper roller, being removed
therefrom by a suitable scraper and falling upon a travelling belt by which it is
carried away.
The oil penetrates the endless blanket, and, trickling down the
lower pressing roller, is collected in the trough placed underneath, or at one side, of
the roller.
In the accompanying drawing
Figure 1 is a perspective view of the apparatus used in the improved process;
all framing and other merely constructive features are omitted, and, for the sake of
greater clearness, all the working parts are shown in their simplest form.
Figure 2 is a cross section of the arrangement of rollers shown in Figure 1.
'
A is the upper pressing roller, and B is the lower pressing roller between which
the belt or blanket C passes.
DE are idle rollers which serve to stretch the belt or blanket.
F is a trough for receiving the oil as it drops from the roller B, and. H is a
scraper for scraping the solid material from the roller A. L is an endless belt to

page_text: remove wax or other solid matter scraped from the roller. Only one roller for
carrying this belt is shown, and the lower half of the belt is omitted.
S is an oil-pipe, having pet-cocks 8 from which sprays of oil o are thrown.
The machine is placed in a room, the temperature of which is kept at the degree
at which it is desired to press the oil; this temperature will vary according to the
nature of the oil operated upon.
The operation of the machine is as follows, that is to say, the oil to be pressed
having been chilled to the proper temperature (and this chilling is a very important
art of the operation,) is thrown in fine sprays upon the endless belt or blanket F
as evenly as is practicable, the said endless belt being in motion and travelling-
over the rollers D E in the direction indicated by the arrows.
The roller D is placed slightly over, and quite near to, the roller A, but not so as
to come into contact with it, the object being to keep the blanket closely pressed
against a considerable portion of the circumference of the latter roller, thus
materially assisting in the separation.
The blanket then passes between the rollers A, B, which latter rollers are pressed
together more or less closely, according to the kind of oil to be pressed. The
paraffine or stearine adheres to the roller A, and is scraped off by the chisel-shaped
scraper H, falling upon the endless belt L by which it is carried to any convenient
place of deposit, either inside or outside the pressing room.
The oil separated from the solid material passes through the belt, and, trickling
down the roller B, is caught by the trough F and carried into a receptacle provided
for it at the end of the roller B.
..
The oil to be operated upon and containing the paraffine, stearine or the like,
instead of being chilled to the desired temperature, before being sprayed, may be
sprayed at its natural temperature at a sufficient, height, so that by its fall and
travel, it becomes sufficiently distributed to quickly assume the temperature of the
surrounding atmosphere and reach the pressing rollers at the proper temperature.
The endless belt or blanket may be composed of felt, cotton, duck, muslin, hair
cloth, or any suitable porous material that will allow the oil separated from the
paraffine wax, or stearine, free passage through it.
In practice a loose cotton cloth is found to work satisfactorily and at less cost
than any other material.
: For economy of construction the rollers B D and E may be made of wood; the
roller A should be of iron, steel, brass, or other hard metal.
The apparatus for spraying may vary, but I have found a pipe fitted with a
number of ordinary cocks, a convenient and practical device. The cocks point
slightly upwards. Any other suitable device for producing a spray may be used.
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 :-
First. The process herein described, for separating paraffine, stearine and other
similar wax-like substances from petroleum or other oils, and consisting in spraying
the mixture of congealable and non-congealable materials upon a porous travelling
sheet or belt, pressing out the liquid portion, and removing the solids from the
press, substantially as set forth.
Second. The process of separating paraffine and other wax-like substances from
oils, comprising the cooling of the mixture, the drawing off of the liquid, the
pressing of the solids while chilled, and the collection of the liquids and solids on
opposite sides of the pressing apparatus, as described.
Third. The apparatus herein described for separating paraffine and other solid
wax-like substance from liquids, consisting of the combination of a spraying
apparatus, a travelling apron or belt, and a pair of pressing rolls all as herein-
before set forth.

page_text: Fourth. In apparatus for separating paraffine and other wax-like substances from
liquids, the combination of a spraying device 8, a belt C, the pressing rolls A and B,
and the scraper H, as set forth.
Fifth. The combination of the blanket or apron C, the pressing rolls A, B, the
scraper H, and the trough F, as described.
Sixth. The combination of the pressing rolls A, B, the scraper H, the trough F,
and the endless carrying belt L, all arranged to operate as described.
