Llewellin, John Llewellin and John Wanklyn James, Brass Founders,
all of Bristol, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF A SELF-ACTING LUBRICATOR FOR LUBRICATING VARIOUS PARTS OF STEAM

Sealed the 17th February 1868, and dated the 21st August 1862.
PROVISIONAL SPECIFICATION left by the said Thomas Clements, Peter
Llewellin, John Llewellin, and John Wanklyn James, at the Office of
the Commissioners of Patents, with their Petition, on the 21st August
1862.
We, THOMAS CLEMENTS, Managing Engineer, & PETER LLEWELLIN, JOHN
LLEWELLIN and JOHN WANKLYN JAMES, Brass Founders, all of Bristol, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF A SELF-ACTING LUBRICATOR FOR LUBRICATING VARIOUS PARTS OF
STEAM ENGINES," to be as follows:-
Our Invention of improvements in the construction of lubricators for
lubricating various parts of steam engines, relates to a novel apparatus,
which, when adapted to the steam supply pipe of an engine, will supply-a

page_text: regulated quantity of the lubricating material to the inside of the valve box and
cylinder, and other working parts of the engine.
The apparatus consists of a steam-tight vessel, for holding oil, tallow, or
other lubricating material, and which is provided with a glass tube, for
shewing the height of the lubricating liquid in the vessel. On the top
of the vessel is placed a funnel, provided with a valve for charging the
vessel; and in order to facilitate this operation, an air cock is fixed in the
top of the vessel for the purpose of allowing the air contained therein to
escape, when the lubricating material is supplied thereto. A similar cock is
also placed at the bottom of the vessel, to admit of the condensed steam or
foul tallow being discharged when required.
The apparatus is attached to the steam pipe by means of any suitable
connection, provided with a cock or valve for regulating the admission of
steam into the vessel through a pipe, carried above the surface of the tallow,
or lubricating material; there is also another pipe, to conduct the oil, tallow,
or other lubricating substance to the slide valve, the cylinder, piston, air pump,
and other internal parts of the engine. By this arrangement of parts the
lubricating substance will be carried forward into the engine by the cur-
rent of steam that is admitted to and made to pass through the vessel,
and will be distributed over the whole of the parts requiring lubrication. By
means of our improved apparatus not only are all the working parts more
thoroughly and efficiently lubricated than heretofore, but a saving of one
half the tallow or lubricating material usually consumed will be effected.
The apparatus is also very simple in its arrangement, and it is capable of
distributing the lubricating substance over the whole of the internal surfaces
of the engine from one source, the supply being capable of being regulated to
the greatest nicety.

the condition (amongst others), that we, the said Thomas Clements, Peter.
Llewellin, John Llewellin, and John Wanklyn James, by an instrument in
writing under our hands and seals, or under the hand and seal of one of us,"
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 we, the said John Llewellin and John Wauklyn
James, on behalf of ourselves, and of the said Thomas Clements and Peter
Llewellin, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the Drawings
hereunto annexed, and to the letters and figures marked thereon (that is to
say):-
•
Our Invention of "improvements in the construction of self-acting lubricators
for lubricating various parts of steam engines, relates to a novel apparatus
which, when adapted to the steam supply pipe of an engine, will supply a
regulated quantity of the lubricating material to the inside of the valve box
and cylinder, and other working parts of the engine.
In the accompanying Drawings, Fig. 1 is a front elevation, and Fig. 2 a
side elevation of the apparatus. complete and ready to be adapted to a steam:
supply pipe; Fig. 3. is a top or plan view of the same, and Fig. 4 a plan of the.
under side.
"
The apparatus consists of a steam-tight vessel a, for holding oil, tallow, or
other lubricating material, and which is provided with a glass tube b for:

page_text: shewing the height of the lubricating liquid in the vessel a.
On the top of
the vessel is placed a funnel c, provided with a valve for charging the vessel a,
and in order to facilitate this operation, an air cock d is fixed in the top of the
vessel a, for the purpose of allowing the air contained therein to escape when
the lubricating material is supplied thereto. A similar cock e is also placed
at the bottom of the vessel, to admit of the condensed steam or foul tallow
being discharged when required.
The apparatus is attached to the steam supply pipe f, by means of any
suitable connection, provided with a cock or valve 9, for regulating the
admission of steam into the vessel a, through a pipe carried above the surface
of the tallow or lubricating material, as shewn by dots in Fig. 1. There is
also another pipe h, to conduct the oil, tallow, or other lubricating substance
to the slide valve, the cylinder, piston, air pump, and other internal parts of the
engine. The pipe h is provided with a cock i, and a divided sector index
plate j. The handle of the cock i is provided with an index or pointer i,
which when the cock is turned to admit the lubricating material from the
vessel a, to pass into the tube h, will indicate the exact extent to which
the cock is open; by this, after a little experience, the engine man
attendant will be enabled to regulate the supply of lubricating material with
great accuracy.
or
It will be understood that when the regulated supply of the lubricating
substance is allowed to pass the cock i into the tube h, it will be carried
forward into the engine, by the current of steam that is admitted to and made
to pass through the vessel a, and into the pipe h, with the lubricating material,
which latter will therefore be distributed over the whole of the parts requiring
Jubrication.
By means of our improved apparatus, not only are all the working parts
more thoroughly and efficiently lubricated than heretofore, but a saving
of one-half the tallow or lubricating material usually consumed will be
effected.
The apparatus is also very simple in its arrangement, and it is capable of
distributing the lubricating substance over the whole of the internal surfaces
of the engine from one source, the supply being capable of being regulated
to the greatest nicety by means of the cock i, as above explained.
Having now described our Invention of improvements in the construction
of a self-acting lubricator for lubricating various parts of steam engines,
and having explained the manner of carrying the same into effect, we claim as
the Invention secured to us by Letters Patent as aforesaid, the mode herein

set forth of causing the steam from the supply pipe to carry with it a regulated
supply of lubricating substance, which will thereby be made to pass through
the valves and internal working parts of the engine as above described.
In witness whereof, we, the said John Llewellin and John Wanklyn
James, have hereunto set our hands and seals, the Twentieth day of
February, in the year of our Lord One thousand eight hundred and
sixty-three.
