Composition for Cooling and Lubricating Frictional Surfaces.
We, ALFRED TOLHURST, and JOHN GROSE TOLHURST, of Nos. 75, 77, 79 and 81,
Tooley Street, in the County of Surrey, Oil Merchants and Refiners, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to a new or improved composition or grease for cooling
and lubricating frictional surfaces and it is of special utility for application to
bearings when these latter become or are liable to become hot from any cause.
The composition or grease is made by mixing together in suitable proportions
certain ingredients such as paraffin wax, Russian tallow, petroleum jelly, castor
oil and flowers of sulphur.
The several ingredients are wholly or partly mixed when in a more or less
heated state and the resulting composition is preferably strained after being made
by passing it through a sieve or the like to ensure the removal of all foreign
matter or grit and stirred or agitated until it has cooled or become set.

Composition for Cooling and Lubricating Frictional Surfaces.
We, ALFRED TOLHURST, and JOHN GROSE TOLHURST, of Nos. 75, 77, 79 and 81,
Tooley Street, in the County of Surrey, Oil Merchants and Refiners, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
Our invention relates to a new or improved composition or grease for cooling
and lubricating frictional surfaces and it is of special utility for application to
bearings when these latter become, or are likely to become hot from any cause.
The composition or grease is made by mixing together in suitable proportions
certain ingredients such as paraffin wax, Russian tallow, petroleum jelly, castor
oil or other suitable vegetable oil and flowers of sulphur.
The several ingredients are wholly or partly mixed when in a more or less
heated state and the resulting composition is preferably strained after being made
by passing it through a sieve or the like to ensure the removal of all foreign
matter or grit and stirred or agitated until it has cooled or become set.
The ingredients which have been found to be most suitable for the purposes

page_text: as above set forth, are paraffin wax (white) with a melting point of about
100° Fahrenheit, best Russian tallow, petroleum jelly castor oil and flowers of
sulphur, the approximate proportions by weight of which have been found by
experience to be as follows:-
Paraffin wax
Russian tallow
Petroleum jelly
Castor, oil
Flowers of sulphur
1
5/16
5/16
1/16
1/16
The tallow and the wax are preferably first melted separately by heat. The
melted wax is then poured into the melted tallow and the petroleum jelly and
the oil added either cold or warm. When this mixture becomes liquid the
flowers of sulphur may be added gradually while slowly stirring. The com-
pound should be strained through a sieve, carefully eliminating any stone or
grit, and frequently stirred until cold.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A cooling grease made of paraffin wax, Russian tallow, petroleum jelly,
castor oil, and flowers of sulphur.
2. A cooling grease formed of the several ingredients in the proportions
stated substantially as set forth.
3. A cooling grease composed of the ingredients stated and made substantially
in the manner set forth.
