page_text: LETTERS PATENT.to Charles Stanley Osborne, of Skinner Street, Bishops-
gate Street, in the City of London, Civil Engineer, for the Invention of
"A NEW COMPOUND APPLICABLE TO THE LINING OR COVERING OF BEARINGS,.
STEPS, AXLE BOXES, JOURNALS, AND OTHER FRICTIONAL PARTS OF MACHINERY,
ALSO TO THE CONSTRUCTION OF PULLEYS, WHEEL TYRES, SCREW PROPELLERS,
AND OTHER LIKE PARTS OF MACHINERY.".
Sealed the 14th September 1866, and dated the 19th March 1866.
PROVISIONAL SPECIFICATION left by the said Charles Stanley Osborne
at the Office of the Commissioners of Patents, with his Petition, on the
19th March 1866.
I, CHARLES STANLEY OSBORNE, of Skinner Street, Bishopsgate Street, in the
City of London, Civil Engineer, do hereby declare the nature of the said
Invention for "A NEW COMPOUND APPLICABLE TO THE LINING OR COVERING
OF BEARINGS, STEPS, AXLE BOXES, JOURNALS, AND OTHER FRICTIONAL PARTS OF
MACHINERY, ALSO TO THE CONSTRUCTION OF PULLEYS, WHEEL TYRES, SCREW
PROPELLERS, AND OTHER LIKE PARTS OF MACHINERY," to be as follows:-.
The new compound which constitutes the essential feature of this Invention
consists of a mixture of what is known as gun cotton (or that product which
results from the action of a mixture of sulphuric and nitric acids upon cotton

page_text: or other vegetable fibre,) together with a vegetable oil, either in its natural
state or as what is known as boiled or oxidized oil, and which compound is
sometimes known as "parksine." With these materials or compounds I
incorporate by the aid of benzole, wood naphtha, or other suitable solvent,
plumbago, steative, and sulphur in a divided state (but in some cases the
sulphur may be dispensed with). In order to impart the necessary degree of
toughness and tenacity to the mass I incorporate therewith cotton or other fibrous
material, the whole being formed into a uniform mass. This compound is to
be compressed so as to render it hard and solid, in which condition it is ready
for application.

'the degree of toughness required.
The purposes to which the herein-before described compound is applicable
are the lining or covering of bearings, steps, axle boxes, journals of shafts and
axles, valves, and valve faces, and other frictional parts of machinery, also the
manufacture of the blades of screw propellers, tyres of railway and other
carriage wheels, and driving and other pulleys.

and at all. times thereafter during the term therein expressed, should and
lawfully might maké, use, exercise, and.vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "A NEW COMPOUND. APPLICABLE. TO THE LINING OR COVERING OF BEARINGS,
STEPS, AXLE BOXES, JOURNALS, AND OTHER FRICTIONAL PARTS OF MACHINERY, ALSO TO
THE CONSTRUCTION OF PULLEYS, WHEEL TYRES, SCREW PROPELLERS, AND OTHER LIKÈ
PARTS OF MACHINERY," upon the condition (amongst others) that I, the said
Charles Stanley Osborne, my executors or administrators, by an instru-
ment in writing under my hand and seal, should particularly describe and
ascertain the nature of the said "Invention, and in what manner. the same
was to be performed; and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Charles Stanley Osborne, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, that is to say:-
The new compound which constitutes the essential feature of my said
Invention consists of a mixture of what is known as gun cotton (or that
products which results from the action of a mixture of sulphuric and nitric
acids upon cotton or other vegetable fibre,) together with a vegetable oil,
either in its natural state or in the state known as boiled or oxidised oil, and
which compound is sometimes known as "parksine." With these materials
or compounds I incorporate, by the aid of benzole, wood naphtha, or other
suitable solvent plumbago, steatite, and sulphur in a divided state (but in
some cases the sulphur may be dispensed with). In order to impart the
necessary degree of toughness and tenacity to the mass I incorporate there-
with cotton or other fibrous material, the whole being formed into a uniform

The amount of fibrous material to be incorporated, with the mass .varies
according to the purposes to which the new compound,is to be applied or to
.the degree of toughness required.
The purposes to which the herein-before described compound is applicable
are the lining or covering of bearings, steps, axle boxes, journals of shafts and

Having now.described and particularly ascertained the nature of my said
Invention, and the manner in which the said is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-before
in part recited Letters Patent is, the manufacture of the peculiar compound
as berein-before described, and the application of the same to the purposes
.specified.
In witness whereof, I, the said Charles Stanley Osborne, have to this
