AN IMPROVED APPLICATION OF STEAM TO VESSELS FILLED WITH OIL, TALLOW, OR MATERIALS FOR LUBRICATING THE CYLINDERS OF STEAM ENGINES OF HIGH OR Low PRESSURE
Year: 1858

page_text: LETTERS PATENT to John Westerby, of Upper Aspley, Huddersfield, in
the County of York, Engineer, for the Invention of "AN IMPROVED
APPLICATION OF STEAM TO VESSELS FILLED WITH OIL, TALLOW, OR
MATERIALS FOR LUBRICATING THE CYLINDERS OF STEAM ENGINES OF HIGH OR
Low PRESSURE."
Sealed the 19th April 1859, and dated the 28th October 1858.
PROVISIONAL SPECIFICATION left by the said John Westerby at
the Office of the Commissioners of Patents, with his Petition, on the
28th October 1858.
I, JOHN WESTERBY, of Upper Aspley, Huddersfield, in the County of York,
Engineer, do hereby declare the nature of the said Invention for "AN IMPROVED
APPLICATION OF STEAM TO VESSELS FILLED WITH OIL, TALLOW, OR OTHER MATERIALS
FOR LUBRICATING THE CYLINDERS OF STEAM ENGINES OF HIGH OR LOW PRESSURE,"
to be as follows:-
This Invention consists in the application or introduction of steam from the
steam chest or valve box, or from the steam pipe or boiler into the grease
cup or vessel attached to the cylinder and containing the lubricating matter
above the surface of the said lubricating matter or material.
And the object and effect of this application is that this steam being of a
higher temperature than that in the cylinder, and consequently of a greater
pressure, will force the lubricating material into the cylinder whatever the
pressure of the steam may be therein.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Westerby in the Great Seal Patent Office on the
28th April 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WESTERBY, of Upper Aspley, Huddersfield, in the County of York, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of October, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said John Westerby, Her special licence that I, the said
John Westerby, my executors, administrators, and assigns, or such others
as I, the said John Westerby, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVED APPLICATION OF STEAM TO VESSELS FILLED WITH OIL, TALLOW, OR
OTHER MATERIALS FOR LUBRICATING THE CYLINDERS OF STEAM ENGINES OP
HIGH OR LOW PRESSURE," upon the condition (amongst others) that I, the
said John Westerby, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 John Westerby, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement in writing, and on reference to the accompanying Drawings, that
is to say:
My Invention is equally applicable to the cylinders of high and low pressure
steam engines, whether such cylinders are placed in a vertical, horizontal, or
diagonal position, and consists in the application or introduction of steam
from the steam chest or valve box, or from the steam pipe or boiler into the
grease cup or vessel attached to the cylinder, and containing the lubricating
matter above the surface of the said lubricating matter or material.
And the object and effect of this application is that this steam being of a

page_text: higher temperature than that in the cylinder, and consequently of a greater
pressure, will force the lubricating material into the cylinder, whatever the
pressure of the steam may be therein.
And in order that my Invention may be perfectly understood, and to explain
the same more in detail, I have annexed hereunto a Sheet of Drawings
illustrative thereof, and have marked the same with figures and letters of
reference corresponding with those in the following explanation, that is
to say:-
Figure 1 shows an exterior elevation of my improved lubricator drawn full
size; Figure 2-shows the application thereof to the lubrication of an horizontal
steam cylinder; and Figure 3 represents the application of the same to a
vertical cylinder, in this latter arrangement the apparatus lubricates the valves
as well as the cylinder.
In Figure 1, a is the cup or vessel containing the oil, tallow, or other
lubricating material, which is filled through the cup 6 and tap c; d is the pipe
leading from the valve chest, steam pipe or boiler, and admitting the steam
above the lubricating material, being opened or closed by the tap e, and fis
the pipe conducting the lubricating material into the cylinder, which is opened
or closed as required by the tap g.
This is the arrangement employed when the lubricating matter is to be
admitted direct into the interior of the cylinder, as shewn at Figure 2; but
when it is desired to admit the lubricating matter through the valve chest so
as to lubricate the valves as well as the cylinder, then the pipe d should be
connected to the steam pipe or boiler, and the pipe f to the valve box or to
the steam pipe immediately in front of the valve box, as shewn at Figure 3 ; but
I would here remark that the lubricator constructed as above described, and
shewn in the Drawings, may be placed in any desired position between the
boiler and cylinder, so long as the steam admitted above the lubricating
material is of a higher temperature and pressure than it is at the point where
the lubricating material is discharged. And it will also be evident that
although conical plug taps for opening and closing the communications are
shewn in the Drawings, any other form of tap or valve may be used with the
same effect.
Having now described the nature and object of my said Invention for
"An Improved Application of Steam to Vessels filled with Oil, Tallow, or
other Materials for Lubricating the Cylinders of Steam Engines of High
or Low Pressure," together with the manner of carrying the same into
practical effect, I desire it to be understood that I claim as my Invention the
introduction above the lubricating matter of steam at a higher temperature

page_text: and pressure than the steam is below the same, or at the point where the
lubricating material is discharged..
In witness whereof, I, the said John Westerby, have hereunto set my
hand and seal, this Twenty-sixth day of April, in the year of our
Lord One thousand eight hundred and fifty-nine.
JOHN WESTERBY. (L.S.)
