PROVISIONAL SPECIFICATION.
An Improved Lubricant for the Lubrication of Hydraulic Rams,
Cylinders, Pumps, and all Surfaces Liable to Corrosion and
Effects of Friction in Water or other Liquids.
I WILLIAM AUSTIN ENTWISTLE 17 Whitworth Street Manchester, in the
County of Lancaster Engineer do hereby declare the nature of this invention to be
as follows:-
My invention relates to the lubrication of all surfaces subjected to friction while
exposed to the corroding effects of water or other liquids. As an example I take
50 parts of stearine or tallow, or other similar substance, 20 parts of soapstone, or
powdered mica or talc, 2 parts of graphite, 10 parts of neatsfoot or other oil,
10 parts of powdered zinc, lead, copper, or other soft metals, & 10 parts of oil of
tar. These incorporate by mixing in any convenient manner: the same will
form a lubricant suitable for all hydraulic purposes, efficacious & lasting in its
effects & protect the wearing or bearing surfaces from corrosion.
In the example now specified there is a large class of substances that may he
substituted for the principle elements named, & which when substituted for them
respectively will be found to be equivalents of the several substances named. Of
course all equivalents of the several substances named in the several compositions
respectively are claimed.
Dated this 25th day of August 1894.

Effects of Friction in Water or other Liquids.
I WILLIAM AUSTIN ENTWISTLE Engineer of 17 Whitworth Street Oxford
Street Manchester in the County of Lancaster 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 :-
My invention relates to lubricating of all surfaces subjected to friction and while
exposed to the effects of water.
As an example, I take 50 parts of stearine or tallow or other similar compound
20 parts of soapstone or powdered mica, or talc, 2 parts of graphite, 10 parts of
neatsfoot oil 10 parts of powdered zinc, lead, copper, or other soft metals and
10 parts of oil of tar. These I incorporate by mixing in any convenient manner,
the same will form a lubricant suitable for all hydraulic purposes, efficacious and
lasting in its effects, and protect the wearing or bearing surfaces from corrosion.
In the example specified, there are a large class of substances that may be
substituted for the principle elements named, and which when substituted for them
respectively, will be found to be equivalents, of course all equivalents of the several
substances named in the several compositions respectively are claimed. I would

page_text: have it understood that I do not confine myself to any particular method for
incorporating or mixing the various ingredients mentioned or their equivalents, as
the object may be accomplished in a variety of ways.
The preparation of a good lubricant for the before mentioned purpose has not in
the past received the attention to which it has been entitled and I believe this to
be the first lubricant specially prepared for the purpose.
It is an established fact, that metalic surfaces rotating or sliding in water are
subject, some more, some less, to the effects of corosion, and also that the surfaces
of the metal itself will in course of time become porous and fluted through wear
and tear, and consequently will not work nearly so well as if the surfaces were in
a perfectly smooth condition.
My invention consists in preparing a lubricant specially for the purpose of
keeping in good condition the rams, plungers, cylinders, pumps and the wearing
surfaces of all kinds of hydraulic machinery, a lubricant consisting of, (among
other ingredients) soft metals powdered so finely as to be almost impalpable;
these soft powdered metals, I then mix with unctuos or any highly lubricating
substances in any convenient manner, and apply the composition to the surfaces to
be protected from corrosion and lubricated.
In my experiments, I have found that the small metalic particles are distributed
evenly over the wearing surfaces, by the sliding or revolving motion of the
machinery, and by this means fill in any uneven surfaces or pores there may be on
the surfaces, and the particles of metal being of a soft or plastic nature, they
readily anheal or wedge themselves into such pores or uneven surfaces, and by this
means make the surfaces smooth, thereby saving a considerable item of expense by
greatly reducing wear & tear of leathers or fibrous material usually used in this
class of machinery also reducing the necessity for returning the rams or boring out
the cylinders.
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
1st. The composition of various ingredients and equivalents before mentioned as
my improved lubricant, and the application in any suitable or convenient manner
to the bearings or wearing surfaces rotary or sliding of all machinery subjected to
friction or corrosion while rotating or sliding either partially or wholly submerged
in water.
2nd. The compound & its application to all wearing and bearing surfaces & all
machinery to which it can conveniently applied.
3rd. I claim each of the several compositions of matter hereinbefore described
when respectively composed of the substances specified or their respective
equivalents and compounding & mixing in any manner by which an equivalent
effect is obtained for the purposes named.
