[Communicated from abroad by EDWIN L. BRADY, New York City, United States
of America, Consulting Engineer.]
An Improved Anti-corrosive Lubricant and Lubricating Vapour for
Carbon Disulphide and other Vapor Motors.
r
I. DAVID SHAPTO HAWKS of Dolcorsllwyn Hall, Cemmes, in the county of
Montgomeryshire, Gentleman do hereby declare the nature of this invention to be as
follows:-
My invention relates to vapor motors and engines in which the elastic force of a
corrosive gas, or vapor such as carbon disulphide is used as the motive power, and
has for its object the preparation of a suitable lubricant for such motors and engines,
and its application thereto in such a manner as to hinder or prevent the corrosive
action of the carbon disulphide vapor upon the metals and packing of the engine.
I treat paraffin oil with a solution of saponin and inject the product into the boiler
of the engine or vapor motor. It thus becomes mixed in a vaporous form with the
motive vapor of carbon disulphide or other vapor and is carried thereby to every part
of the boiler and engine that would otherwise be corrosively affected by the carbon
disulphide or other corrosive vapor.
Paraffin and perhaps some of the refined products of petroleum being the only
oils suitable for the purpose all animal and vegetable fats and oils being chemically
affected by carbon disulphide vapor.
COMPLETE SPECIFICATION.
An Improved Anti-corrosive Lubricant and Lubricating Vapor for
Carbon Disulphide and other Vapor Motors.
I DAVID SHAFTO HAWKS of Dolcorsllwyn Hall, Cemmes, in the county of
Montgomeryshire, gentleman 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 vapor motors and engines in which the elastic force of
carbon disulphide or of a corrosive gas or vapor such as carbon disulphide is
used as the motive power; and has for its object the preparation of a suitable
lubricant for such motors and engines, and its application thereto in such a manner as
to binder or prevent the corrosive action of the carbon disulphide vapor or other gas
upon the metals and packings of the engine.
For the preparation of this lubricant I take a weak solution of saponin-say one
ounce saponin to five quarts of water and with it I wash, shake together, or in other
Five quarts of the above
ways thoroughly mix, paraffin or other light mineral oil.
solution will affect thirteen quarts of paraffin. The paraffin almost immediately
becomes thickened to a creamy consistency and of a soapy nature. It is now ready
for use, and I apply it by injecting it into the boiler or vapor generator of the
motor at the same time and together with the motive-vapor-producing liquid.-The
nature of the paraffin when thus prepared is such that it is mixed with, and borne
along by, the inotive vapor, and thus becomes applied to every part of the boiler
and engine that is reached by the motive vapor, protecting such parts from the evil
effects thereof.

page_text: Upon the condensation of this lubricating vapor such part of the lubricant as has
passed entirely through the engine readily disengages itself from the carbon
disulphide or other vapor-producing liquid, and may be again used.
Sufficient lubricant should be fed into the boiler or generator as to be distinctly
traced in the condensed carbon disulphide or other motive vapor after having passed
through boiler, engine, and condenser.
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. As a new article of manufacture, the product of saponin and paraffin or other
light mineral oil, herein. before described.
2. The method of preparing paraffin or other light mineral oil for use as a
lubricant for carbon disulphide or other vapor motors, substantially as herein before
set forth.
3. The method of application of such prepared paraffin or other mineral oil as a
lubricating vapor to carbon disulphide or other vapor motors, substantially as herein
before described.
