WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. AN IMPROVED PROCESS AND APPARATUS FOR
OBTAINING OIL FROM PETROLEUM, RESIN AND OTHER SUBSTANCES." [A com-
munication from abroad by John Emil Borne, of Brooklyn, New York, United.
States of America.]
The Invention relates to an improved process and apparatus for obtaining oil
from petroleum, resin, and other substances, as hereinafter described.
In carrying the said Invention into practice I provide a still, properly arranged
over a furnace, and of any appropriate size and construction. From the top of
this still a pipe leads to the upper compartment of a separator which is of
cylindrical form, and divided into two chambers by a partition. A pipe supplied
with a cock passes from the upper part of the said separator to a condensing tank
filled when in use with a cooling agent. The end of the last named pipe which
enters the tank connects with a condensing coil which issues at the bottom of the
tank, so as to lead any matter in it off to a receiving receptacle.
The upper compartment of the separator communicates with the lower
compartment of same through an elbow also supplied with a cock to break the
connection when desired. The upper end of the elbow will enter the separator at
a point slightly above the partition, while the lower end penetrates into the lower
compartment and terminates just above a series of parallel perforated plates,
preferably of thin sheet metal, and supported on a horizontal plane in any
convenient manner. From the opposite side of the separator to the said elbow and
flush with the upper surface of the partition a pipe extends away from the
separator, and terminates immediately over a receptacle. Opposite to the lower'
D

page_text: arm of the aforesaid elbow in the lower compartment of the separator is supplied a
precautionary pipe which passes from the separator to a condensing tank, wherein
it connects with a condensing coil. From the lower end of the separator a pipe
having a cock leads to the condensing tank, where it is also connected with
another condensing coil.
The various parts of the apparatus above described may be of any suitable
dimensions, and will be arranged with relation to each other as the operator may
desire.
The fire having been made in the furnace, the crude material to be treated is
placed in the still and heated to from about 400° to 800° Fahrenheit (according to
circumstances), which will effect distillation of the matter, and cause portions of it
to ascend in the form of vapor into the upper part of the separator, whence the
lighter parts of the vapor pass into the condensing coil situated in the tank, and
issue therefrom in the form of a pure oil.
The heavier vapors which enter the upper chamber of the separator, as aforesaid,
pass downward through the elbow into the lower chamber of same, wherein those
particles which are light enough enter the precautionary pipe, and pass off into one
of the condensing coils issuing therefrom in pure oil, while those portions of greater
specific gravity together with such oil as may have been condensed in the separator
percolate downward through the plates, and are conveyed away from the separator
and into the other condensing coil. The precautionary pipe will also serve to
relieve the separator of any overcharge of the gaseous vapors.
The pipe leading from the separator to the receptacle aforesaid operates to carry
off any gummy matters that may lodge in the upper part of the separator.
The oil as it issues from the condensing coils is produced by a single distillation,
whereby time, labor, and fuel are saved; it is a product which will stand a high
fire test, and is equal in color to a triple distilled oil; it is of neutral flavor, and is
an article of great superiority.
It will be observed that the vapors are allowed to pass from the still as rapidly
as they are generated, and there is no possibility of their being discolored or
otherwise injuriously affected by being retained in the still.
The apparatus after use will be cleaned by the introduction of steam or
otherwise as may be convenient.
I do not limit myself to the treatment of any particular substance, as various
materials may be manipulated successfully according to my process, and by means
of my apparatus.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED PROCESS AND APPARATUS FOR
A com-
OBTAINING OIL FROM PETROLEUM, RESIN, AND OTHER SUBSTANCES."
munication from abroad by John Emil Borne, of Brooklyn, New York, United
States of America.
This Invention relates to an improved process and apparatus for the manufacture
of oil from petroleum or the products theroof, shale or the products thereof, or
resinous substances, as hereinafter fully described.
In the accompanying Drawing;-
Figure 1 is a central vertical longitudinal section of an apparatus embodying the
elements of the said Invention.
Figure 2 is an enlarged similar view of the separator.
A indicates the still properly arranged over a furnace B and of appropriate size
and construction. From the top of the still A a pipe C leads to the upper com-
partment of a separator D, which is of cylindrical form, and divided into two
chambers by a partition a. A pipe E provided with a cock passes from the upper
part of the separator D to a condensing tank F, which is filled when in use with
a suitable cooling agent. The end of the pipe E which enters the tank F connects
with a condensing coil b, which issues at the bottom of the tank so as to lead any.
matter in it off to a suitable receptacle.
The upper compartment of the separator D communicates with the lower compart-
ment of the same through the elbow H, also provided with a cock so as to break the
connection when desired. The upper end of the elbow will enter the separator D at
a point flush with the upper surface of the partition a, while the lower end of the
said elbow penetrates into the lower compartment and terminates just above a series
of parallel perforated plates d, preferably of thin sheet metal, and supported in a.
horizontal plane in any convenient manner.
From the opposite side of the separator D to the elbow H and flush with the
upper surface of the partition a, the pipe I, provided with a cock, extends away
from the separator D, and terminates immediately over a receptacle J. Opposite
to the lower arm of the elbow H in the lower compartment of the separator D is a
precautionary pipe K, which passes from the separator D to the condensing tank L
wherein it connects with the coil e.
From the lower end of the separator D a pipe M, having a cock f, leads to the
condensing tank L, where it also connects with a condensing coil M.
The various parts of the apparatus above described may be of any suitable
dimensions and arranged with relation to each other as desired.
The fire having been made in the furnace B, the material to be treated is placed
in the still A and heated to from about 400° to 800° Fahrenheit (according to
circumstances) which will effect a distillation of the material, and cause portions
thereof to ascend in the form of vapor through the pipe C into the upper part of
the separator D, from which the lighter parts of the vapor pass through the pipe E
into the condensing coil 6 situated in the tank F, and issue therefrom in the form
of pure fine oil. The heavier vapors which enter the upper chamber of the
separator D, as aforesaid, pass downward through the elbow H into the lower
chamber of the same wherein those particles of vapor which are light enough enter
the precautionary pipe K and pass off into the condensing coil e, issuing therefrom
in the form of pure oil, while those particles of vapor of greater specific gravity,

page_text: together with such oil as may have been condensed in the separator D, percolate
downward through the plates d, and are conveyed away from the separator D and
into the condensing coil N by the pipe M. The pipe K will also serve to relieve
the separator D of any over-charge of the gaseous vapors.
The pipe I operates to carry off any gummy matters that may lodge in the upper
part of the separator D.
The oil as it issues from the condensing coils is produced by a single distillation,
whereby time, labor and fuel are saved; it is a product which will stand a high
fire-test and is equal in color to a triple distilled oil; it is of neutral flavor, and is
an article of great superiority.
It will be understood that the vapors are allowed to pass from the still as rapidly
as they are generated, and there is no possibility of their becoming discolored or
otherwise injuriously affected by being retained in the still.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it understood
that I claim,
First. The process herein described of producing oil from petroleum or the
products thereof, shale or the products thereof, or resinous substances, which
process consists in heating the materials to about from 400 to 800 degrees
Fahrenheit, and allowing the lighter vapors to pass off as they are generated
into and through a separator and into a condenser.
Second. The process herein described of producting oil from petroleum or the
products thereof, shale or the products thereof, or resinous substances, which consists
in heating the materials to from about 400 to 800 degrees Fahrenheit, and, allowing
the vapors to enter a separator, whence the lighter vapors pass off to a condenser
and the heavier vapors pass downward through perforated plates, and with such oil
as may have become condensed in the said separator are conveyed to another
condenser.
Third. The separator D having two compartments communicating with each
other through an elbow or pipe H, the upper compartment being supplied with the
pipes C, E, I, and the lower compartment with the pipes K, M, and the plates d,
substantially as above set forth and for the purpose specified.
Fourth. The apparatus herein described consisting of the furnace and still, the
separator constructed as set forth, and the condensers, as and for the purpose
specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Eighteenth day of June, in the year of our Lord One
thousand eight hundred and eighty one
W. ROBT. LAKE. (L.S.)
