page_text: TTLE'S SPE
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LITTLE, of 198, Strand, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Sixteenth day of
April (One thousand eight hundred and forty-nine), in the twelfth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Little, my exors, adiñors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said William Little,
my exors, adiiors, and assigns, or such others as I, the said William Little,
my exors, adiñiors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF MATERIALS FOR LUBRICATING MACHINERY,"
communicated to me from a certain foreigner residing abroad; in which said
Letters Patent is contained a proviso, that I, the said William Little, shall
cause a particular description of the nature of the said Invention, and in what
manner the same is to be performed, by an instrument in writing under my
hand and seal, to be inrolled in Her said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said
in part recited Letters Patent, as in and by the same, reference being there-
unto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Little, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, that is to say:-
The Invention consists of employing products from petroleum in the manu-
facture of lubricating materials for machinery, such as are required for axle-
trees of locomotive engines, and other axles requiring similar lubricating matters,
and also more fluid lubricating matter. And in order that the Invention may
be most fully understood, and readily carried into effect, I will proceed to describe
the means practised by the Inventor, as communicated to me :-
The petroleum is to be distilled in order to obtain the requisite products;
for this purpose I cause the petroleum to be distilled, and for economy's sake
I collect the products which first come over for the purposes of light, and
when the products begin to come over of a greasy character, these pro-
ducts are to be received into a separate vessel or receiver, and the distillation
is to be continued till only so much remains as will prevent the burning of
the still. When the petroleum is of that character as will wholly distill
over, and the residue in the still remains of a greasy character, I do not distill
off the whole, but allow some to remain to prevent the still burning, which
residue I draw off after cooling the still, and these products will be both
applicable for making lubricating matter for machinery. In other classes of
petroleum a residue of a pitchy character will remain in the still. After
distilling over the greasy matter, such bituminous matter is to be removed
before again charging the still. The greasy matters thus obtained are to be
made into suitable lubricating matters in the following manner :-Into a large
copper or cauldron I put in at the rato of thirty-two parts of tallow, or other
suitable fatty matter, with seventy-five parts by weight of soda ley of 10° or
11° of Beaumé, and I gradually heat the same to boiling, and when saponi-
fication is taking place, I add twenty-nine parts by weight of water, and raise
the matters again to the boiling point. I then pour the same into a vessel
containing forty-five parts of the greasy products of petroleum, and well stir-
the whole. I then allow the mass to cool and acquire a proper consistency.
When the oil or lubricating matter required to be of a more liquid character,
then I employ the more fluid portion of the greasy or oily products which first
come over, and I boil the same with about ten per cent. by weight of soda
ley, and when a thick white vapour appears, the matters are to be allowed to
cool down, and the same will then be suitable for lubricating machinery.
Having thus described the nature of the Invention, and the manner in
which the same is to be performed, I would state that I do not confine myself

page_text: to the details, as herein described, so long as lubricating matters for machinery
are manufactured by the application of products of petroleum.
In witness whereof, I, the said William Little, have hereunto set my
hand and seal, this Fifteenth day of October, in the year of our
Lord One thousand eight hundred and forty-ninc.
AND BE IT REMEMBERED, that on the Fifteenth day of October, in the
year of our Lord 1849, the aforesaid William Little came before our said
Ladly the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Enrolled tho, Sixteenth day of October, in the year of our Lord One
thousand eight hundred and forty-nine.
