City of Manchester, Gentleman, for the Invention of "IMPROVE-
E
Scaled the 18th November 1853, and dated the 5th July 1853.
PROVISIONAL SPECIFICATION left by the said John Fall at
the Office of the Commissioners of Patents, with his Petition,
on the 5th July 1853.
I, JOHN FALL, of Chorlton upon Medlock, in the City of Manches-
ter, Gentleman, do hereby declare the nature of the said Invention
for IMPROVEMENTS IN THE TREATMENT OF CERTAIN OILS" to be as
follows:-
My Invention consists in dissolving common yellow resin, colophony,
burgundy, pitch, terchenthine, or turpentine materials as they exude
from the tree, copaiva resins, and the products of the distillation of all
such resins, gum damar, gum thus, balsams, wax, caoutchouc, gutta-
perèla, and such like resinous and gummy matters in oils procured by
distilling coals, peat, petroleum, bitumens, asphalts, shales, blaes, schists,

page_text: and other mineral substances capable of yielding bituminous matters
by the application of heat, so as to thicken and improve such oils,
and render them suitable for lubricating machinery, manufacturing
wools, and the like animal substances, and other useful purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Fall in the Great Seal Patent Office, on
the 28th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN FALL, of Chorlton upon Medlock, in the City of Manchester,
Gentleman, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of July, in the year of our
Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Fall, Her special licence that T, the said
John Fall, my executors, administrators, and assigns, or such others as
I, the said John Fall, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, excrcise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN THE TREATMENT OF CERTAIN OILS," upon
the condition (amongst others) that I, the said John Fall, by an instru-
ment in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Fall, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say):

page_text: My Invention consists in dissolving common yellow resin, colophony,
burgundy, pitch, terebrenthine, or turpentine materials as they exude
from the tree, copaiva resins, and the products of the distillation of;
such resins, gum damar, gum thus, wax, balsams, and such like
resinous and gummy matters (herein-after called by me resinous and
gummy matters) in oils procured by distilling coals, peat, petroleum,
bitumens, asphalts, shales, schists, blaes, and other mineral substances
capable of yielding bituminous matters by the application of heat, so.
as to thicken and improve, such oils, and render them more suitable.
for lubricating machinery, manufacturing wools, and the like animal
substances, and other useful purposes. The oils I deem best suited for
my purpose are the light oils produced from peat and the mineral-
substances above mentioned by distillation at a low temperature, and
are known at present by the names of, paraffine and eupion oils, which
oils are thin in consistency, and from that cause have not yet been
much used for lubricating purposes, owing to the circumstance of their
running away from the machinery to which they are applied when it is
in motion. This defect I propose to remedy by combining such oils
with the resinous and gummy matters before named, and thus giving
them body, and rendering them more suitable to be applied for the
purpose of lubrication. In the manufacturing of wools and the like
animal substances paraffine and eupion oils have not been employed,
owing to their want of body and the circumstance of their not being
easily washed out of the wool when manufactured, but when in union,
with resinous and gummy matters before mentioned the latter combine..
with alkaline solutions, and thus assist in the removal of the oil.
Having thus stated the nature of the Invention, I will proceed to
describe the manner in which the same is to be performed. I employ
in preparing the said lubricating and wool manufacturing materials a
large boiler or heating vessel, heated either by fire, steam, hot air, or
otherwise. In this vessel I place the oil to be operated ou, and to quicken
the solution of the rosin I heat the oil up to two hundred degrees of
Fahrenheit's thermometer; I then add the resinous or gummy matters,
preferring to use common yellow resin, but the other substances before
mentioned will answer the purpose (which have previously been

page_text: reduced to powder, or divided into small pieces when solid), by placing
them in a bag made of woollen cloth, or some other good filtering
material, and suspending it from a suitable support in the midst of the.
oil. By these means the resinous and gummy matters are dissolved in
the oil, whilst any impurities they may contain are left in the filter.
When all the soluble parts of the resinous and gummy matters have
been combined with the oil the filter can be removed, and having been
well cleansed may be again filled with resinous and gummy matters,
and placed in the oil, as before mentioned. I have found equal quanti-
ties of the mineral oil and resinous and gummy matters to produce
superior lubricating materials; that is, one hundred weight of yellow
resin to one hundred weight of mineral oil, and the same proportions
I have found to produce an oil for manufacturing wools and the like
animal substances, but the oil can be made thinner for light machinery.
by keeping out some of the resin, or a thicker oil can be made, if.
desired, by adding more than the proportions here stated, varying the
thickness of the oil according to the kind of machinery to be lubri
cated. The above proportions I specify rather as guides, and do not
confine myself to them only, for these proportions and the manner of
dissolving the resinous and gummy matters may be greatly varied.
Having stated the nature of the Invention, and the manner of per-
forming the same, I would have it understood that what I claim is, the
the combination of the materials herein described in preparing lubri-
cating matters for machinery, and in preparing oils for manufacturing
wool and such like animal substances, and other useful purposes.
In witness whereof, J, the said John Fall, have heretofore set my
hand and seal, this Seventeenth day of December, in the
year of our Lord One thousand eight hundred and fifty-three.
JOHN FALL. (L.S.)
