I ALFRED GEORGE WASS of 122 Raymouth Road Bermondsey in the County of
Surrey Engineer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following stateinent :-
The object of my invention is to produce and provide for use in and with engines
and shafts and bearings and other places and purposes an extremely efficient lubricant.
To carry out this object I take any convenient and suitable animal vegetable or
mineral oils and I dissolve therein preferably by heat as much asphalium as I may
desire which in most cases is as much as the oil can easily and conveniently carry and
the asphaltum so treated may be of any kind and in any condition either as the same
comes from the mines or elsewhere or after use on roads or pavements or otherwise as
only the soluble portion of the asphaltum will be so dissolved in and carried by the
oil the residuum if any being deposited on the bottom of the vessel or chamber in which
this process aforesaid has been effected. In some cases and more especially when the
oil is required for lubricating heavy bearings I can then conveniently add thereto a
small proportion of glycerine say five per centum or thereabouts or if the asphaltum
so treated as aforesaid has or developes any gumming properties or tack a somewhat
similar proportion of litharge or ashes of lead or zinc or tin can also be added to
destroy the same.
The oil so treated as aforesaid can then if required be strained or otherwise treated
in any usual or other manner and is ready for use and it will be found that the
properties and qualities thereof have been greatly improved by this treatment afore-
said and the utility and efficiency thereof as a lubricant vastly increased. For example
when take a shale oil of say 880 specific gravity or thereabouts and dissolve
therein as much asphaltum as this oil can easily and conveniently carry the specific
gravity thereof is raised to 930 or thereabouts and this oil so treated is a much more
capable lubricant than it was before such treatment, and the required lubrication can
be effected thereby at a reduced cost. Again for example when
take a tar oil of say
1-200 specific gravity or thereabouts and dissolve therein as much asphaltuun as this

page_text: oil can easily and conveniently carry the specific gravity thereof is reduced to
1100 or thereabouts to the great improvement of its lubricating properties.
This lubricant so made as herein before described can be used in the form of a grease
or as a solid lubricant by saponifying the same in and by any usual process or other-
wise such for example as by the lime process when the litharge or ashes of lead or
zinc or tin has or have been added to the oil so treated with asphaltum as is herein-
before described.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1. The lubricant made by dissolving asphaltum in oil substantially as and for the
purpose herein before described and declared.
2. The lubricant made by the combination of oil with asphaltum and glycerine or
litharge or ashes of lead or zinc or tin substantially as and for the purposes herein-
before described and declared.
3. The lubricant made by the combination of oil with asphaltum and litharge or
ashes of lead or zine or tin the whole combination being saponified substantially as
hereinbefore described.
