page_text: 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 statement :-
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 a certain proportion as is herein-
after stated of resin to give body and substance to the oil and of liiharge or ashes of
lead or zine or tin to destroy the gumming properties or tack of the resin. When
the viscosity of the oil is low or on other occasions when I may deem it desirable so
to do I can then add to this compound a certain proportion as is hereinafter stated of
any suitable animal vegetable or mineral greases or stearines or scales which will give
still more body and substance to the oil so treated as aforesaid and which ingredients
when used are also dissolved preferably by heat therein and as a liquid or semi-liquid
this lubricant is then ready for use.
This lubricant so made as herein before described can if desired be used in the form
of a grease or as a solid lubricant by saponifying the same in and by any usual
process or otherwise and I consider that the lime process of saponification is very
suitable for use in and with this my invention.
The proportions of the several ingredients aforesaid in this lubricant are varied and
regulated by the nature and viscosity of the oil and by the quality of the resin and in
the case of the solid lubricant by the degree of stiffness and consistency required
in the grease and by the height of the desired melting point thereof.
For example
when I take a Scotch shale oil of say 880 specific gravity I have found that an
extremely efficient. lubricant is produced by dissolving therein about twenty five
per centum of resin five per centum of litharge or ashes of lead or zinc or tin and
twenty five per centum of animal grease and when this lubricant is saponified by the
lime process I produce a grease the melting point whereof is high. When the
viscosity of the oil is greater than in the example aforesaid I can reduce in a somewhat

page_text: similar proportion the aforesaid proportion of the grease and if desired a somewhat
smaller proportion of the resin and vice versa. The proportion also of the litharge or
ashes of lead or zine or tin so required for the purpose aforesaid is varied and
regulated by the quality of the resin the low class quality thereof requiring a larger
proportion of the litharge or ashes of lead or zinc or tin and vice versa.
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 resin and litharge or ashes of lead or zinc
or tin in oil substantially as and for the purposes hereinliefore described and declared.
2. The lubricant made by the combination of oil with resin and litharge or ashes of
lead or zine or tin and grease or stearine or scale substantially as and for the purposes
hereinbefore described and declared.
3. The lubricant made by the combination of oil with resin and litharge or ashes of
lead or zinc or tin the whole combination being saponified substantially as hereinbefore
described.
4. The lubricant made by the combination of oil with resin and litharge or ashes of
lead or zinc or tin and grease or stearine or scale the whole combination being
saponified substantially as hereinbefore described.
