DI BUITICATION.
An Improved Lubricant or Compound for Preventing Over-heating of
the Bearings of Revolving Shafts and other Frictional Surfaces in
Machinery.
I, WILLIAM HENRY STERRATT, of 18, Mealhouse Lane, Atherton, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:
-
My said invention relates to an improved lubricant or compound for preventing
the over-heating of the bearings of revolving shafts and frictional surfaces
generally.
My improved compound consists principally of tallow to which is added oil
of tar, and common salt (sodium chloride).
To every pound avoirdupois of tallow I add from 1 to 2 drachms oil of tar
and 1 to 2 ounces of salt. These proportions may however be varied to some extent.
The oil of tar and salt might be mixed with the tallow when the tallow is in a
solid state or the tallow may be first melted to facilitate the mixing of the
ingredients.
My improved lubricant or compound may be applied to the bearings instead of
the usual lubricant, or any suitable fubricant may be used and my improved
compound applied when necessary to absorb the heat from the bearings or frictional
surfaces which have become overheated.
