THOMAS HOLCOMBE, of No. 6, Bankside, in the Borough of Southwark, Iron
Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing date at Westminster, the Sixth day of May, in the Fourth

LUBRICATING OR PRESERVING MATTERS FOR WHEELS AND AXLES, APPLICABLE ALSO
TO THE BEARINGS, JOURNALS, AND OTHER PARTS OF MACHINERY;" in which said
Letters Patent there is contained a proviso, obliging me, the said Charles
Thomas Holcombe, by an instrument in writing under my hand and seal,
particularly to describe and ascertain the nature of my.said Invention, and
in what manner the same is to be performed, and to cause the same to be

and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Thomas Holcombe, do hereby declare that the nature of my said
Invention, and the manner. in which the same is to be performed, are parti-
cularly described and ascertained in and by the following description thereof,
that is to say:
The object of my Invention, so far as relates to lubricating matters, is to
render a certain, mineral grease, the production of coal tar, and commonly
called naphthaline, when mixed up and manufactured with the materials and
in the manner described in the first, second, and third processes herein-after
set out, useful and applicable for lubricating the wheels, axles, bearings, and
journals of machinery; and the object of my Invention, so far as relates to
lubricating and preserving matters, is to render a certain mineral oil, also
the production of coal tar, and commonly called dead oil, when mixed up and
manufactured with the materials and in. the manner described in the fourth
process herein-after set out, useful and applicable for lubricating wheels,
axles, bearings, and journals of machinery, and for preserving any wheels,
axles, bearings,, journals, and other parts, of machinery when externally
applied thereto; which Invention I propose to carry into, effect in the manner
herein after; described, that is to say,:-
First process. I take of naphthaline in the rough and: chrystalized state.
about five hundredweight,, and, boil it for about three hours, with, about two
or three bushels of tan;; and I also, boil therewith about thirty-five pounds
weight of soda.. Sometimes I boil animal charcoal alone with the naphthaline,
and sometimes I boil, catechu, commonly called japan, earth, with the. napli-
thaline. The, naphthalino; thus, prepared, either with the tan; and soda, or
with the animal charcoal or catechu, is strained through a fine wire sieve
and left to cool. I now melt together, about, forty pounds weight of: rosin, and
thirty pounds weight of bone or horse fat, thirty-five pounds weight of: Russia
tallow, and two hundredweight of palm oil. as, a mixture; and: I grind this:
mixture with the napthaline, when so, prepared either with the tan, and soda,
or with the animal charcoal or catechu as aforesaid, in a mill similar in all
respects to, a common paint mill..
Second process. I take about three hundredweight of the.napthaline. when
prepared. as in the first process, either with the tan and soda, or with the
animal charcoal or catechu; I then; mix with it about twenty-three..pounds:
weight of blacklead, and twenty pounds weight of Stockholm. tar; and I
grind the whole together in a mill similar in all respects to a common paint

page_text: mill. The grease thus formed is of an inferior quality. to, that, described. in
the first process.
Third process.-I take about three hundredweight: of napthaline,, when
prepared as in the first process, either. with the tan and soda, or with, the,
animal charcoal or catechu, and mix it with twenty-eight. pounds; weight; of
Stockholm tar, and. twenty-eight. pounds weight. of bone fat, or any other
suitable fatty vegetable or animal substance; I grind the whole together in a.
mill similar in all respects to a common paint mill. The grease thus, fornied
is of quality still inferior to that described in the second process.. Some-
times I add a quantity of rosin in the manufacture of the grease described
in the second and third processes; and I decrease in such second and third
processes the quantity of tar and soda, animal charcoal,, or catechu used in
the boiling, in proportion to. the difference. in the quantity of napthaline used
in the first, second, and third processes.
In the above descriptions I do not mean to confine myself to any particular
mode of manufacturing, nor to any particular quantities or proportions of
the materials or ingredients used; but my claim is solely for the use of
napthaline as the basis of my Invention in lubricating matters.
Fourth process. I put a quantity of about fifty or sixty gallons of the
dead oil before mentioned into a pan or cauldron, and boil it with about one
bushell of tan; or I boil the same with catechu alone, or with catechu and
tan; I also boil about twenty-eight pounds weight of soda with the dead
oil and tan, or with the dead oil and catechu alone, or catechu and tan;
I then strain the mixture off and let it cool; when cool I bag it in the same
manner as sperm oil is usually bagged; I then add about two pounds weight of
palm oil or two pounds weight of horse grease to each gallon of the mixture;
but the palm oil or horse grease may be added in the same proportion before
the mixture is bagged.
In the above description I do not mean to confine myself to any particular
mode of manufacturing, nor to the particular quantities or proportions of
the ingredients used; but my claim is solely for the use of dead oil as the
basis in such lubricating matters and preserving matters, when so mixed, in
manner aforesaid, with any proportion of animal or vegetable oils or grease.
In witness whereof, I, the said Charles Thomas Holcombe, have here-
unto set my hand and seal, this Sixth day of September, One thousand
eight hundred and forty-one.
C. T. (L.s.) HOLCOMBE.
