This Invention relates to improvements upon an Invention, for which Patrick
Moir Crane, one of the present applicants, obtained Letters Patent on the 13th day
of January 1879, entitled " Improvements in the Mauufacture of Grease for
Lubricating Purposes, No. 146, and consists in taking the grease produced in
accordance with the Specification of the said Letters Patent, and after the same has
been washed with water or treated with alkali solution, and subsequently washed
with water, and subjecting such grease to pressure in any of the usual modes
whereby we are enabled to separate the liquid and solid portions, the liquid consti-
tuting a lubricating oil of good body, whilst the more solid portion which remains
is a wax suitable for candle making, stiffening, and other analogous purposes for
which hydro-carbon wax has hitherto been used.

This Invention relates to improvements upon an Invention for which Patrick
Moir Crane, one of the present applicants, obtained Letters Patent on the 13th day
of January 1879, entitled 'Improvements in the Manufacture of Grease for
Lubricating Purposes, No. 146, and consists in taking the grease produced in
accordance with the Specification of the said Letters Patent, and after the same has
been washed with water or treated with alkali solution, and subsequently washed
with water, and subjecting such grease to pressure in any of the usual modes, for
instance, by screw or hydraulic pressure, whereby we are enabled to separate the
liquid and solid portions; the liquid constitutes a lubricating oil of good body,
whilst the more solid portion which remains is a wax suitable for candle making,
stiffening, match making, and other analogous purposes for which hydro-carbon wax
has hitherto been used.
Having thus particularly described and ascertained the nature of this our said
Invention, together with the best methods with which we are acquainted for
carrying the same into practical effect, we wish it to be distinctly undertood
that we do not confine ourselves to the precise details herein before described, as
the same may be varied without departing from our Invention, and that we
claim,―
1st. The manufacture of lubricating oil in the manner and substantially as herein-
before described.
'
2nd. The manufacture of wax in the manner and substantially as herein before
described.
In witness whereof, I, the said Patrick Moir Crane, on behalf of myself and
the said Richard Moir, have hereunto set my hand and seal, this 26th day
of November, in the year of our Lord 1879.
