IMPROVEMENTS IN STEAM ENGINE LUBRICATORS
Year: 1874

page_text: LETTERS PÅTENT to Jesse Lumb, of Folly Hall, Huddersfield, in the
County of York, Worsted Spinner, and Sam Bottomley, of the samo
Place, Engine Tenter, for the Invention of "IMPROVEMENTS IN STEAM
ENGINE LUBRICATORS."
Sealed the 9th February 1875, and dated the 12th August 1874.
PROVISIONAL SPECIFICATION left by the said Jesse Lumb and
Sam Bottomley at the Office of the Commissioners of Patents, with
their Petition, on the 12th August 1874.
We, JESSE LUMB, of Folly Hall, Huddersfield; in the County of York;
Worsted Spinner, and SAM BOTTOMLEY, of the same Place, Engine Tenter;
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN STEAM ENGINE LUBRICATORS," to be as follows :—
-
This Invention relates to means of supplying oil, grease, or other
lubricant to the pistons and cylinders of steam engines at such times
and in such quantities as may be required or desireable. This we accom-
plish as follows:-
The oil, grease, or lubricant is supplied by a cup and tap to á chamber;
-

page_text: but instead of employing an ordinary valve or tap, as usual, for admitting
or allowing the lubricant to pass into the cylinder when operated by the
attendant we make use of a tap having a series of cavities or recesses cut
or formed partly through or into the spindle-or-plug. On the projecting
end of the spindle is fixed a ratchet wheel, and hinged to said spindle is
a lever and catch or pawl taking into the ratchet-teeth. This lever is
connected by a rod to the radius rod, cross head, beam, or other moving
part of the engine in such manner as to obtain reciprocatory motion,
and so to turn the ratchet wheel by a certain number of teeth, ono or
more, at every stroke of the piston. The cavities in the plug become
charged with lubricant from tho chambor, which is carried to and passes
through an opening into the cylinder at intervals which are regulated by
the speed of the ratchet wheel. The cavities in the plug of the tap may
be of any size and number as found requisite, and the speed or motion
given thereto by the ratchet wheel may be regulated as desired so as to
admit or supply the necessary quantity of lubricant to the cylinder.
t
The receptacle for the lubricant may be a simple cup with our improved
tap thereto, but we prefer to have an intervening chamber with ordinary
tap to prevent possible escape of steam.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Jesse Lumb and Sam Bottomley in the Great Seal
Patent Office on the 12th February 1875.
.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JESSE
LUMB, of Folly Hall, Huddersfield, in the County of York, Worsted
Spinner, and SAM BOTTOMLEY, of the same Place, Engine Tenter, send a
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of August, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and -8
successors, give and grant unto us, tho said Jesse Lumb and
Sam Bottomley, Her special licence that we, the said Jesse Lumb and
Sam Bottomley, our executors, administrators, and assigns, or such
others as we, the said Jesse Lumb and Sam Bottomley, our executors,
.

page_text: 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 "IMPROVEMENTS IN
STEAM ENGINE LUBRICATORS," upon the condition (amongst others) that we,
the said Jesse Lumb and Sam Bottomley, our executors or admini-
strators, by an instrument in writing under our, or their, or one of their
hands and seals, should particularly describe and ascertain the nature
1 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 Jesse Lumb and Sam Bottomley,
5 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 (that is to say) :-
This Invention relates to means of supplying oil, grease, or other
lubricant to the pistons and cylinders of steam engines at such times and
) in such quantities as may be required or desirable.
Our method of accomplishing this object will be readily understood
by the following description, reference being made to the accompanying
Sheet of Drawings, in which Figs. 1 and 2 are elevations of lubricator ;
Fig. 3 being a sectional view of Fig. 1.
The oil, grease, or lubricant is supplied by a cup and tap to a chamber,
receptacle, or receiver A attached to the cylinder cover in the usual
manner, but instead of employing an ordinary valve or tap, as usual, for
admitting or allowing the lubricant to pass into the cylinder to be
operated when required by the attendant we make use of a tap having a
series of cavities B or recesses cut or formed partly through the spindle
or plug C. On the projecting end of the spindle is fixed a ratchet
wheel D, and hinged to said spindle is a lever E and catch or pawl F
taking into the ratchet teeth. This lever is connected by a rod to the
radius rod, cross head, beam, or other moving part of the engine in such
3 manner as to obtain reciprocatory motion, and to turn the ratchet wheel
a certain number of teeth, one or more, at every stroke of the piston.
The cavitics in the plug become charged with lubricant from the

page_text: chamber, which is carried to and passes through an opening into the
cylinder at intervals which are regulated by the speed of the ratchet
wheel. The cavities in the plug of the tap may be of any size and
number, as found requisite, and the speed or motion given thereto by the
ratchet lever may be regulated as desired so as to admit or supply the 5
necessary quantity of lubricant to the cylinder.
The receptacle for the lubricant may be a single cup with our improved
tap thereto, but we prefer to have an intervening chamber with ordinary
tap to prevent possible escape of steam.
In witness whereof, I, the said Sam Bottomley, for and on behalf 1
of myself and the said Jesse Lumb, have hereunto set my händ,
this Eleventh day of February, in the year of our Lord One
thousand eight hundred and seventy-five.
