AN IMPROVED FORM OF LUBRICATOR
Year: 1862

page_text: LETTERS PATENT to John Tomlinson Pendlebury, Blacksmith, and Thomas
Pendlebury, Mechanic, both of Bury, in the County of Lancaster, for
the Invention of "AN IMPROVED FORM OF LUBRICATOR."
PROVISIONAL SPECIFICATION left by the said John Tomlinson Pendle-
'bury and Thomas Pendlebury at the Office of the Commissioners of
Patents, with their Petition, on the 15th March 1862.
We, JOHN TOMLINSON PENDLEBURY, Blacksmith, and THOMAS PENDLEBURY,
Mechanic, both of Bury, in the County of Lancaster, do hereby declare the
nature of the said Invention for "AN IMPROVED FORM OF LUBRICATOR," to be as
follows:-
Our Invention consists of an improved form of grease cock for lubricating
cylinders, pistons, pumps, and other mechanism; which lubrication is effected
by the action of the machine itself.
We construct the cock with a funnel at the top, of the usual form, for
receiving the oil or other lubricating material. The cone or plug we make
hollow, and fitted with a stuffing box and projecting spindle of any convenient
form. This plug or cone has an aperture corresponding in size with the hole
in the bottom of the funnel for allowing the oil to pass into it. Another hole
is placed near this last-mentioned one, coinciding with a tube passing up
through the centre of the funnel holding the oil, having its mouth above the

page_text: surface of the tallow or oil for the purpose of allowing the escape of the air.
A third hole is formed in the opposite side of the plug from the two last-
mentioned ones, which is closed or turned off when the two others are
in position. A pipe passing up through the funnel of the cock, connected
with the inside of the cylinder, or with the boiler, so as to allow the passage of
the steam up through it. This pipe is connected with this last hole. A
passage
is formed through the stem of the cock, passing into the cylinder in
the usual manner. The operation is as follows:-The cock being turned so
as to bring the aperture in it so as to coincide with the hole in the funnel,
the oil will run down and fill the hollow plug, the air going off by the pipe
passing up through the funnel. The plug is then reversed by a lever or other
contrivance connected with the machinery, which brings it over the passage in
the stem, and also the third hole in connection with the pipe from the cylinder
or boiler, which by means of the pressure of the steam forces the oil down the
stem and into the cylinder.. The lever on the spindle then turns the plug,
and the same action is repeated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Tomlinson Pendlebury and Thomas Pendlebury in
the Great Seal Patent Office on the 15th September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,.JOHN
TOMLINSON PENDLEBURY, Blacksmith, and THOMAS PENDLEBURY, Mechanic,
both of Bury, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign,, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Tomlinson Pendlebury and Thomas Pendlebury, Her special
licence that we, the said John Tomlinson Pendlebury and Thomas Pendlebury,
our executors, administrators, and assigns, or such others as we, the said
John Tomlinson Pendlebury and Thomas Pendlebury, our executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all tinies 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 FORM OF LUBRICATOR," upon. the
condition (amongst others) that we, the said John Tomlinson Pendlebury

page_text: our Invention, though particular, modifications can be employed to suit par-
ticular circumstances.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation of our grease cock or lubricator; Fig. 2 is a section
of the same, and Fig. 3 is a side elevation of the ratchet and pinion.
g
is a receptacle for holding the oil, tallow, or other lubricating material,
the passage or flow of which is regulated, by means of the cone or plug b.
This plug has formed in it a hole or slot c for allowing the oil to pass into the
interior of the cone, and also another, aperture coinciding at a certain position
with the pipe e communicating with the steam from below the plug, or from the
boiler, or main steam pipe; or otherwise as convenient. The ratchet wheel,
is fixed on the extremity of the plug or cone, and is worked by the lever h and
the catch i. We also employ an intermediate ratchet wheel for regulating
the quantity of the oil. or tallow, to be let into the cylinder or place to be lubri-
cated. It will be evident that by attaching the lever to any portion of the
machinery the lever will be actuated at certain intervals, making the hole or
slot c. coincide alternately with the receptacle for the oil or tallow and the
passage leading into the cylinder or other portion of the machinery to be
lubricated.
.
Having now described our. Invention, and how the same is carried into
effect, we wish it understood that what we claim and desire secured to us by
the before in part recited Letters Patent is, the construction and use of a
lubricator or grease cock in which a pipe or tube is used or employed to
convey the steam from below the plug, or from the steam boiler or main
steam pipes into the interior of the plug or cone, so as to force the oil or
tallow into the cylinder, bearing, or other place to be lubricated.

In witness whereof, we, the said John Tomlinson Pendlebury and Thomas
Pendlebury, have hereunto set our hands and seals, this Thirteenth
day of September, One thousand eight hundred and sixty-two.

page_text: and Thomas Pendlebury, our executors or administrators, by an instrumentiin
writing under our, 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 nexts and imme-
diately after the date of the said Letters Patent..
NOW KNOW YE, that we, the said John Tomlinson Pendleburyi and
Thomas Pendlebury, do hereby declare the nature of our said Invention;
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
Our Invention consists of an improved form of grease cock for lubricating
cylinders; pistons, pumps, and other mechanism, which lubrication is effected
by the action of the machine itself.

We construct the cock with a funnel at the top, of the usual form, for
receiving the oil or other lubricating material. The cone or plug we make
hollow, and fitted with a stuffing box and projecting spindle of any convenient
form. This plug or cone has an aperture corresponding in size with the hole
in the bottom of the funnel for allowing the oil to pass into it. Another hole
is placed near this last-mentioned one coinciding with a tube passing up
through the centre of the funnel holding the oil, having its mouth.above thé
surface of the tallow or oil for the purpose of allowing the escape of the air.
A third hole is formed in the opposite side of the plug from the two last,
mentioned ones, which is turned off when the two others are in position. A
pipe passing up through the funnel of the cock connected with the inside' of
the cylinder, or with the boiler, so as to allow the passage of the steam up
through it. This pipe is connected with this last hole. A passage is formed
through the stem of the cock, passing into the cylinder in the usual manner:
The operation is as follows: -The cock being turned so as to bring the
aperture in it so as to coincide with the hole in the funnel, the oil will run
down and fill the hollow plug, the air going off by the pipe passing through
the funnel. The plug is then reversed by a. lever or other contrivance con-
nected with the machinery, which brings-it over the passage in the stem, and
also the third hole in connection with the pipe from the cylinder or boiler,
which by means of-the-pressure of the-steam-forces-the-oil down the stem and
into the cylinder. The lever on the spindle then turns the plug, and the
same action is repeated..

same is carried into effect, we have to this Specification appended the accom-
panying Drawings, which are intended to shew the best method of applying
