AN IMPROVED LUBRICATOR OR TALLOW Cup
Year: 1867

page_text: LETTERS PATENT to John Bates, of 101, Eldon Street, in the Parish of
Sheffield, in the County of York, Mechanical Engineer, for the Invention
of "AN IMPROVED LUBRICATOR OR TALLOW Cup."
PROVISIONAL SPECIFICATION left by the said John Bates at the
Office of the Commissioners of Patents, with his Petition, on the
23rd February 1867.
I, JOHN BATES, of 101, Eldon Street, in the Parish of Sheffield, and
County of York, Mechanical Engineer, do hereby declare the nature of the
said Invention for "AN IMPROVED LUBRICATOR OR TALLOW CUP," to be as
follows:-
This Invention relates to an improved construction of lubricator or tallow
cup applicable to steam engines, steam stamps, steam hammers, or other
machines worked by steam, the construction being more simple, economical,
and efficient than in ordinary lubricators, there being no liability to leakage or
want of repair.
The lubricator consists of a small cup with a perforated plate or grid
whereby the tallow or oil is properly strained before entering the cylinder,.
which is a very essential element in a good lubricator. The cup is set on a
vertical spindle fitted with two internal steam-tight plugs, which are kept
down on their bearing by a hollow nut. A port or opening is formed in the
upper plug for the passage of the oil into the lubricator from the cup; the
spindle is turned by a handle, and an index shows the position of the bottom

page_text: plug, so as to indicate whether the communication with the interior of the
engine and the lubricator is cut off or not. When the top plug covers the
upper port the lower port is opened by the bottom plug, and the steam rushes
through and presses on the surface of the lubricating material, putting it in a
state of equilibrium, consequently it drops down by its own gravity, and can
be regulated to take only one drop at each stroke of the engine, steam
hammer, or other machine, and not one drop of the lubricating matter can
get out of the lubricator except the engine is in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Bates in the Great Seal Patent Office on the
23rd August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BATES, of 101, Eldon Street, in the Parish of Sheffield, and County of York,
Mechanical Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Bates, Her special licence that I, the said John Bates, my
executors, administrators, and assigns, or such others as I, the said John
Bates, 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 LUBRICATOR
OR TALLOW CUP," upon the condition (amongst others) that I, the said John
Bates, 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 Bates, 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 state-
ment-

page_text: My Invention relates to an improved construction of lubricator or tallow
cup applicable to cylinders of steam engines, steam stamps, steam hammers,
or other machines worked by steam, the construction being more simple,
economical, and efficient than in ordinary lubricators, there being no liability
to leakage or want of repair.
.
The lubricator consists of a small cup with a perforated plate or grid,
whereby the tallow or oil is properly strained before entering the cylinder,
which is a very essential element in a good lubricator. The cup is set on a
vertical spindle fitted with two internal steam-tight plugs, which are kept
down on their bearing by a hollow nut. A port or opening is formed in the
upper plug for the passage of the oil into the lubricator from the cup; the
spindle is turned by a handle, and an index shews the position of the bottom
plug, so as to indicate whether the communication with the interior of the
engine and the lubricator is cut off or not. When the top plug covers the
upper port the lower port is opened by the bottom plug, and the steam rushes
through and presses on the surface of the lubricating material, putting it in a
state of equilibrium, consequently it drops down by its own gravity, and can
be regulated to take only one drop at each stroke of the engine, steam
hammer, or other machine, and not one drop of the lubricating matter can get
out of the lubricator except the engine is in motion.
Fig. 1 represents (in the annexed Drawings) an external elevation of a
lubricator for locomotives, and Fig. 2 represents a section of the lubricator,
the outline of which is suitable for stationary engines, steam hammers, and
steam stamps.
a is a small cup with a perforated plate or grid, whereby the tallow or oil
is properly sieved before entering the cylinder, which is strongly recommended
to be done; B, B, is a perpendicular spindle fitted with two internal steam-
tight plugs shewn at c, c, which are kept down on their bearing by the hollow
mut D; E is a small port where the tallow or oil enters into the lubricator
communicating with the cup a; F is the index shewing the position of the
bottom plug c, the index finger pointing at S shows that the communication
with the interior of the engine and lubricator is cut off. When the index
finger points at O, which is done by turning the handle g, the top plug C
covers the port E and opens the ports H, J, in the bottom plug C, the steam
rushing up the hole J gets on the surface of the lubricating matter at J,
putting it into a state of equilibrium, consequently it drops down the hole H
by its own gravitation, and. can be regulated as before described, even if the
lubricator be full and the communication between the engine and lubricator
be wide open.

page_text: Fig. 3 shews a different arrangement in regard to the ports H, J, wherein
the two ports communicate or are united in the bottom plug, so that when the
index finger points at O and the piston. is returning towards the cylinder cover
the steam rushes up the port H to the port K, and through the hole j, gets on
the top of the lubricating matter at J, putting it in a state of equilibrium, and
at every down stroke of the piston draws the lubricating matter through the
port H, and mixing with the stean greases all the internal parts of the
engine, steam stamp, steam hammer, or other machine where the lubricator
may be applicable.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark in conclusion that I do
not limit myself to any precise configuration of lubricator, as the shape may
be varied to suit varied requirements; but I claim as my improvements the
construction of the spindle B, the arrangement of the ports E, J, H, I, and
the arrangement shewn in Fig. 4, where the ports I and H communicate at
the junction K, also the internal steam-tight plugs C, C, and flange nut D
threaded inside for adjusting spindle B, all substantially as and for the purposes
herein specified.
In witness whereof, I, the said John Bates, have hereunto set my hand
and seal, this Nineteenth day of August, in the year of our Lord One
thousand eight hundred and sixty-seven.
Witness,
FRANK BURNBY,
Broomhall Park,
Sheffield.
