We, CHARLES STINEMAN GILBERT, a citizen of the United States, residing at
Race Street, of Millersburgh in the County of Dauphin, and State of Pennsylvania,
U.S.A. Inventor, and JAMES FRANKLIN THOMPSON, a citizen of the United
States, residing at Liverpool, in the County of Perry, and State of Pennsylvania,
U.S.A. Physician, do hereby declare the nature of this invention to be as
follows:--
This invention consists of a liquid metallic composition or compound which is
adapted for use as an anti-friction lubricant and journal cooler and which consists
of the following ingredients combined in the proportions below set out and said
ingredients and said proportions being substantially as follows, the gallon being
employed as a standard, and for the purposes of convenience:
1. One gallon of mineral lubricating oil of low specific gravity;
2. One gallon of mineral lubricating oil of high specific gravity;
3. One gallon of lime water;
4. One quart of rosin oil;
5. One pound of sulphate of soda;
6 One pound of black antimony
7. One half pound carbonate of magnesium powdered.
In preparing the above named articles and combining the same, I first slack
freshly burnt lime and add sufficient water to make it the consistency of ordinary
white-wash, and when the lime has subsided and the liquor has become clear,
decant or pour off the clear water, and this will form the lime water employed in
the compound.
I then take one gallon of lime water thus produced, and add one pound of
sulphate of soda, and heat the product until a temperature of about ninety to
ninety-five degrees is reached, and hold the same at this temperature until the soda
is entirely dissolved.
To this warm solutior, 1 add the one pound of black antimony and one half
pound cf carbonate of magnesium, and allow the product to stand for six hours or
thereabouts, and to this product add the one gallon of mineral lubricating oil of
light specific gravity, and the one quart of rosin oil.
I then place this compound in a mixing mill such as is used in the manufacture
of ready mixed paints, and to this compound, I add one gallon of mineral
lubricating oil, and mix all thoroughly, and after the same has been thoroughly
mixed and compounded in the mixing mill, it is thrown off and strained and put
into barrels or cans.
In preparing this compound, the following directions should be observed. For a
light bodied lubricant such as meets the requirement of high speed engines and high
speed machinery, the last gallon of lubricating oil which is added must be of very
high specific gravity, and for heavy stationary engines and slow running machinery,
all the oil employed may be of the same or nearly the same specific gravity. For
a heavy compound the last gallon of mineral oil added should be composed of
petroleum of residuum commonly known as "tank bottoms" and this constitutes a
compound unsurpassed for railroad cars, heavy mining machinery, cranes, very
7. One half pound carbonate of magnesium powdered.
In preparing the above named articles and combining the same, I first slack
freshly burnt lime and add sufficient water to make it the consistency of ordinary
white-wash, and when the lime has subsided and the liquor has become clear,
decant or pour off the clear water, and this will form the fime water employed in
the compound.
I then take one gallon of lime water thus produced, and add one pound of
sulphate of soda, and heat the product until a temperature of about ninety to
ninety-five degrees is reached, and hold the same at this temperature until the soda
is entirely dissolved.
To this warm solutior, I add the one pound of black antimony and one half
pound cf carbonate of magnesium, and allow the product to stand for six hours or
thereabouts, and to this product add the one gallon of mineral lubricating oil of
light specific gravity, and the one quart of rosin oil.
I then place this compound in a mixing mill such as is used in the manufacture
of ready mixed paints, and to this compound, I add one gallon of mineral
lubricating oil, and mix all thoroughly, and after the same has been thoroughly
mixed and compounded in the mixing mill, it is thrown off and strained and put

a heavy compound the last gallon of mineral oil added should be composed of
petroleum of residuum commonly known as "tank bottoms" and this constitutes a
compound unsurpassed for railroad cars, heavy mining machinery, cranes, very

known as "axle-grease."
My improved compound, or liquid lubricant and journal cooler will not settle
to the bottom of the barrel or can, or become solidified, but will remain in a
perfect fluid condition, the various parts remaining in complete suspension and
solution therein.

COMPLETE SPECIFICATION.
An Improved Lubricant.
We, CHARLES STINEMAN GILBERT Inventor and JAMES FRANKLIN
THOMPSON Physician, the latter late of Liverpool, in the County of Perry,
Pennsylvania, U.S.A. both residing at Race Street, Millersburgh, in the County
of Dauphin and State of Pennsylvania, United States of America, 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:-
This invention consists of a liquid metallic composition or compound which is
adapted for use as an anti-friction lubricant and journal cooler and which consists
of the following ingredients combined in the proportions below set out, and said
ingredients and said proportions being substantially as follows, the gallon being
employed as a standard, and for the purposes of convenience.
One gallon of mineral lubricating oil of low specific gravity;
One gallon of mineral lubricating oil of high specific gravity;
One gallon of lime water;
One quart of resin oil;
One pound of sulphate of soda;
One pound of black antimony;
One-half pound carbonate of powdered magnesium.
In preparing the above named articles and combining the same, I first slack
freshly burnt lime and add sufficient water to make it the consistency of ordinary
white wash, and when the lime has subsided and the liquor has become clear,
decant or pour off the clear water, and this will form the lime water employed in
the compound.
I then take oue gallon of lime water thus produced, and add one pound of
sulphate of soda, and heat the product until a temperature of about ninety to
ninety-five degrees is reached, and hold the same at this temperature until the soda
is entirely dissolved.
To this warm solution, I add the one pound of black antimony and one-half
pound of carbonate or magnesium, and allow the product to stand for six hours or
thereabouts, and to this product add the one gallou of mineral lubricating oil of
light specific gravity, and the one quart of resin oil.
I then place this compound in a mixing mill such as is used in the manufacture
of ready mixed paints, and to this compound, I add one gallon of mineral 4
lubricating oil, and mix all thoroughly, and after the same has been thoroughly
mixed and compounded in the mixing mill, it is drawn off and strained and put
into barrels or caus.
In preparing this compound, the following directions should be observed, for
a light bodied lubricant such as meets the requirement of high speed engines and 5

page_text: high speed machinery, the last gallon of lubricating oil which is added must be of
very high specific gravity, and for heavy stationary engines and the slow running
machinery, all the oil employed may be of the same or nearly the same specific
gravity. For a heavy compound the last gallon of mineral oil added should be
composed of petroleum residuum, commonly known as "tank bottoms" and this
constitutes a compound unsurpassed for railroad cars, heavy mining machinery,
cranes, very heavy bearings, etc., and will surpass and supplant what is now on the
market known as "axle-grease."
My improved compound, or liquid lubricant and journal cooler will not settle
to the bottom of the barrel or can, or become solidified, but will remain in a
perfect fluid condition, the various parts remaining in complete suspension and
solution therein.
It is evident that slight changes in, and modifications of the formula herein given,
and also in the directions for its preparation, may be made without departing from
the spirit of my invention or sacrificing its advantages, and I may also, under
certain conditions omit one gallon of the mineral oil which forms a part of the
compound, it being observed that two gallons are employed in the formula, one
of which is of greater specific gravity than the other.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The composition herein described, which consists in the combination of
mineral oil, lime water, resin oil, sulphate of soda, black antimony, and carbonate
magnesium, substantially as and for the purpose set forth.
2. The composition herein described, consisting of the following named parts or
ingredients combined in the following proportions; one gallon of mineral oil, of low
specific gravity, one gallon of mineral of high specific gravity, one gallon of lime
water, one quart of resin oil, one pound of sulphate of soda, one pound of black
antimony, and one half pound of carbonate of magnesium, said parts being combined,
substantially as shown and described.
3. A lubricating compound, containing soluble metals, and mineral or other oils,
as and for the purpose set forth.
