Improvements in or relating to the Production of Lubricants.
I, PAUL RAOUL DE FAUCHEUX D'HUMY of 136 Princes Road, Liverpool in
the County of Lancaster, Civil and Naval Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention has for its object the production of a lubricant, the said substance
being so prepared that it will not corrode the metal or leave grit which is so liable
to injure the bearings or other working parts of machinery.
The best proportions I have found so far are as follows, but these can be varied
to suit circumstances, such as variations in temperature, and the special purposes for
which the lubricant is to be used-
Crude petroleum
Spermaceti
Paraffin wax
Pitch pine wood sawdust
Soda -
about 48 parts
""
5 parts
"
15 parts
20 parts
"
12 parts.
"
I dissolve the spermaceti and the paraffin wax in the crude oil, which is heated
to a temperature of 250 degrees Fahrenheit until the liquid turns into a clear syrup.
I then add the pitch pine wood sawdust and the soda, and boil again until 10 per cent.
of the total mass has evaporated, and then I add 10 per cent. of water and agitate
the compound over a gentle fire until a soft paste is formed. The crude oil,
petroleum, spermaceti and paraffin wax form the body of the material, while the
pitch pine sawdust has for its object to prevent the lubricant running too freely
when used, and adds to its lathering qualities.
I do not however confine myself to the above receipt, as the proportions of the
various substances used may depend upon the purpose for which the lubricant is
required, and the variations in temperature to which the lubricant is likely to be
subjected.

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 :-

Shale oil and other mineral lubricating oil can take the place of crude petroleum.
The paraffin wax can be dispensed with if the petroleum or shale oil has been
partially distilled and is therefore much richer in the paraffins, solid at ordinary
temperatures than ordinary crude petroleum.
The pitch pine wood sawdust can be superseded by other forms of cellulose and
turpentine and resin.
I dissolve the spermaceti and the paraffin wax in the crude oil, which is heated
to a temperature of 250 degrees Fahrenheit until the liquid turns into a clear
syrup. I then add the pitch pine wood sawdust and the soda, and boil again until
10 per cent. of the total mass has evaporated, and then I add 10 per cent. of
water and agitate the compound over a gentle fire until a soft paste is formed.
The crude oil, petroleum, spermaceti and paraffin wax form the body of the material,
while the ingredients of the pitch pine sawdust with the exception of the cellulose
are dissolved and the addition of the sawdust has for its object to prevent the
lubricant running too freely when used, and adding to its lathering qualities, the
finely diffused cellulose being very useful.
In giving the above quantities, I do not bind myself to them as they can be much
varied without great injury, just as the ingredients as above described can be varied,
but the above receipt is that which my experiments would indicate to be the best
for general purposes. It can be thinned down if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture or production of lubricants substantially as herein
described.
2. In the manufacture or production of lubricants the combination with alkali
and hydrocarbons of pitch pine wood or its equivalent as described, in great part
dissolved in the alkali and hydrocarbons.
