AN IMPROVED LUBRICATING COMPOUND
Year: 1871

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine,
Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "AN IMPROVED LUBRICATING COMPOUND."-A com-
munication from abroad by William Salamon, of the City and State
of New York, United States of America.
Sealed the 7th October 1871, and dated the 1st July 1871.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition, on
the 1st July 1871.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "AN IMPROVED LUBRICATING COMPOUND,"
a communication, to be as follows :—
To make my improved lubricating compound I take one pound of
caustic soda in a liquid form at about 15° Baumé, two pounds of tallow,
four pounds of petroleum oil. These ingredients are placed together
in a kettle on a fire or are otherwise subjected to licat until the

page_text: mixture ceases to foam, which it will do at a temperature of about
500° Fahrenheit, the whole forming a semi-fluid substance when cold.
By this operation the compound will lose about 20 per cent. of its
weight, it will not melt or take fire from ordinary or light friction, and
will be of a consistency of ordinary lubricating grease. I then place
the mixture in bags or other enclosures and subject it to pressure,
which is continued until as much of the oil or liquid substance is
removed as desirable. This oil or liquid and the compound left may
be used for lubricating purposes in any desirable manner. To this
pressed compound I add animal hair in the proportion of 5 pounds of
hair to 100 pounds of the pressed compound, and thoroughly mix or
incorporate them together. In this form the said compound may be
used in ordinary lubricating boxes or receptacles without cotton waste
or other packing.
From the above description it will be seen that the said compound is
produced in three forms, viz., first, a semi-fluid substance for use in
lubricating cups; second, an oil or liquid to be used with or without
cotton waste or other packing; third, the prepared semi-fluid substance
or compound mixed with animal hair.
The combination of materials and the treatment above described will
produce good results, but I do not limit my Invention to the exact
proportions or the precise treatment set forth.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Scal Patent
Office on the 30th December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of July, in the year of our
Lord One thousand eight hundred and seventy-one, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Robert Lake, Her special licence
that I, the said William Robert Lake, my executors, administrators,

page_text: and assigns, or such others as I, the said William Robert Lake, 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, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
LUBRICATING COMPOUND," a communication to me from abroad by William
Salamon, of the City and State of New York, United States of America,
upon the condition (amongst others) that I, the said William Robert
Lake, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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 William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement:-
To make my improved compound I take one pound of caustic soda in
a liquid form at about 15° Baumé, two pounds of tallow; and four
pounds of petroleum oil. These ingredients are placed in a kettle over
a fire or are otherwise subjected to heat until the mixture ceases to
foam;
the cessation of foaming will occur at a temperature of about
$ 500° Fahrenheit, the compound forming a semi-fluid substance when
cold. By this operation the compound will lose about 20 per cent. of
its weight, it will not melt or take fire from ordinary or light friction,
and will be of the consistency of common lubricating grease. I then
place the compound in bags or other enclosures, and separate from it a
portion of its oil or liquid by pressure. This pressure is continued
until as much of the oil or liquid is removed from the compound as
shall be found desirable, and both the liquid and the remaining portions
of the compound are to be used for lubricating purposes in any required
or convenient manner. To this pressed compound I sometimes add
animal hair in the proportion of five pounds of hair to one hundred
pounds of the pressed compound, and thoroughly mix or incorporate
them together. In this form the said compound may be used in ordinary
lubricating boxes or receptacles without cotton waste or other packing.

page_text: From the above description it will be seen that the said compound is
produced in three forms, videlicet first, a semi-fluid substance for use in.
lubricating cups; second, an oil or liquid to be used with or without
cotton waste or other packing; and, third, the semi-fluid substance or
compound mixed with animal hair.
Having thus described the said Invention as communicated to me by
my foreign correspondent, I wisli it understood that although the pro-"
portions and treatment of the ingredients of my compound above given
will produce good results, I do not limit myself strictly to such propor-
tions or treatment, but may vary either to such an extent as will not
involve a departure from the essential nature of my said Invention;
and I claim,
First. A lubricating compound consisting of caustic soda, tallow, and
petroleum oil, combined in or about in the proportions and by the
treatment herein set forth.
Second. Combining with the aforesaid semi-fluid compound animal
hair in or about in the proportions set forth for the purpose specified.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Twenty-ninth day of December,
in the year of our Lord One thousand eight hundred and seventy-
one.
Witness,
W. J. LOWE.
