PROVISIONAL SPECIFICATION left by the said John Talbot Pitman at
the Office of the Commissioners of Patents, with his Petition, on the
11th August 1859.
I, JOHN TALBOT PITMAN, of the American & European Patent Offices,
No. 67, Gracechurch Street, London, do hereby declare the nature of the said
Invention for "A COMPOSITION APPLICABLE TO THE LUBRICATION OF MACHINERY,
AND TO VARIOUS OTHER USES."-A communication from abroad by Horace
Vaughn, of the City of Providence, in the State of Rhode Island, one of the
United States of North America," to be as follows:-
In combining lime, sulphur, soap stone (or French chalk), or, instead of
the last, an additional amount of the sulphur in certain general proportions,
by means of water, then adding a quantity of prepared chalk and calcined
magnesia. Instead of the chalk, fuller's earth may be used. After standing,
the supernatant liquor, mixed with an equal quantity of oil, is to be used as
a lubricator for heavy machinery. To reduce its consistency, & adapt it for
fine machinery, sal soda, pearlash, alcohol, hartshorn, soda ash, potash, or
other like chemical substances may be mixed with it, in proportions varying

page_text: according to the ingredients selected & the particular use of the compound.
Sal soda is in general considered the best, and may be used at the rate of
about an ounce for every four gallons of the compound. For softening
paints & to increase their covering power the compound may be mixed with
linseed oil in equal parts. For greasing wool, two parts of the compound
may be added to one of oil. It may also be used in cleaning cloth soiled by
grease, greasing saws and cutlery, and other similar uses. The proportions
used are not imperative, and in some cases the magnesia, in others the soap
stone, may be dispensed with, and so of some of the other ingredients.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Talbot Pitman in the Great Seal Patent Office on the
10th February 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TALBOT PITMAN, of the American and European Patent Offices, No. 67, Grace-
church Street, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of August, in the year of our Lord
One thousand eight hundred and fifty-nine, in the
year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Talbot Pitman, Her special licence that I, the said John
Talbot Pitman, my executors, administrators, and assigns, or such others as
I, the said John Talbot Pitman, 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 "A
COMPOSITION APPLICABLE TO THE LUBRICATION OF MACHINERY, AND TO VARIOUS
OTHER USES," a communication from Horace Vaughn, of the City of Pro-
vidence, in the State of Rhode Island, one of the United States of North
America, upon the condition (amongst others) that I, the said John Talbot
Pitman, 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.

page_text: NOW KNOW YE, that I, the said John Talbot Pitman, 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:-
The chief object of this Invention is the production of a compound appli-
cable to the lubrication of machinery of every kind, which can be reduced to.
any desired consistency, according to the character of the machinery upon
which it is to be used, and which, while effecting the lubrication in a superior.
and more economical manner, shall at the same time cool the parts to which
it is applied, and prevent the rubbing surfaces from heating or cutting..
The compounds made use of for these purposes are also applicable to a.
variety of other uses, such as the greasing of wool, greasing saws and cutlery,
mixing with paints to increase their covering power, the cleaning of cloth
soiled by grease, &c., all of which purposes are contemplated, and come within.
the scope of the Invention.
The manner of preparing the cooling lubricator is as follows:-In a forty,
gallon cask place from forty to fifty pounds of lime, and pour upon it soft
water until the lime is nearly slaked. While the water is hot add 4 lbs..
prepared chalk, 4 to 6 lbs. fullers' earth, 1 lb. of calcined magnesia, and from
to of a pound of sal soda, and of a pound of sulphur; stir it well
together, and fill the cask with water; stir it again, and let it stand until it
has settled. say, from twelve to twenty-four hours, so that it will soak, and
cut the sulphur well. The proportion of these ingredients may be varied, and
the fullers' earth may be omitted, substituting in its place prepared chalk,
soap stone, if necessary. The longer it stands, the more the peculiar virtue
of the sulphur will be extracted. When the mixture has settled, the super-
natant fluid is ready for use, and may be drawn off at once, or as required..
It is as pure, clear, and soft as rain water in appearance and effects. To
form with the liquid thus prepared a compound adapted to the lubrication of
heavy machinery, it is necessary to mix it with an equal quantity of oil, when
a lubricating material is produced which is perfectly smooth and free from.
grit, prevents gumming and rust, is admirably adapted to heavy machinery,
being highly cooling in its effect upon the journals and other rubbing parts,
and which can be produced at a cost not exceeding half that of oil. When
used to soften paints and increase their covering power, it should be mixed
with linseed oil, in the proportions of equal parts of each. When employed
for greasing wool, it should be mixed with oil, in the proportion of two parts
of the compound to one of oil. The proportions stated are not imperative,
nor is it absolutely necessary that all the ingredients should be employed, but

page_text: they are given as those which experience has thus far shown to be the best.
In some cases the magnesia may be dispensed with, and in others the soap
stone, and so of the other ingredients, as herein-before intimated. The
lubricating compound produced, as described, is found to be too thick in con-
sistence for use upon very fine machinery, it becomes advisable, therefore, to
reduce it. For this purpose sal soda, pearlash, alcohol, hartshorn, soda ash,
potash, and other like substances may be used, in proportions varying according
to the ingredients selected, and the particular character of the lubricating
compound upon which it is proposed to operate. It has been found, however,
that sal soda is the best and most advantageous of the substances named, it
will, therefore, be selected in describing the process. Take of the lubricating
compound, say, thirty gallons, add to it eight ounces of sal soda dissolved in
three pints of water, and stir the mixture well until the solution of sal soda
is completely amalgamated with the compound. The quantity of the soda
solution to be added will vary with the kind of oil of which the lubricating
compound has been made. Sperm oil, for example, being heavier than lard
oil, requires more of the sal soda solution to thin it; but the proportion for
each kind of oil will readily be discovered by an experiment of a few minutes.
I wish it distinctly understood that I do not claim lime water when used
alone for the purpose of mixing with oil to form a lubricating compound.
Having thus fully described the Invention as communicated to me, what
I claim and desire to secure under the herein-before in part recited Letters
Patent, is,―
First, the solution first herein described for forming with oil a cooling
lubricator, and for other purposes as mentioned, and this I claim without
intending to limit myself to the specific proportions named or to the ingre-
dients, varying the same in the manner indicated, so long as the principle of
the Invention is the same.
Second, I claim thinning the lubricating compound by means of a solution
of sal soda, or of the other substances named, or of any substance having
practically the same chemical qualities.
In witness whereof, I, the said John Talbot Pitman, have hereunto set
my hand and seal, on this Third day of February, Anno Domini, One
thousand eight hundred and sixty.
