Year: 1869

page_text: LETTERS PATENT to Charles Henry Gardner, of West Harding Street,
Fetter Lanc, in the City of London, Engineer, for the Invention of
Ax IMPROWED LUBRICATOR"
Sealed the 26th November 1869, and dated the 1st June 1869.
PROVISIONAL SPECIFICATION left by the said Charles Henry Gardner
at the Office of the Commissioners of Patents, with his Petition,
on the 1st June 1869.
I, CHARLES HENRY GARDNER, of West Harding Street, Fetter Lane,
in the City of London, Engineer, do hereby declare the nature of the
said Invention for "AN IMPROVED LUBRICATOR," to be as follows:-
This Invention relates to an improved lubricator or apparatus for
lubricating.
My apparatus.consists of a chamber, vessel, or receiver closed on
all sides, or nearly so, except at the bottom where a small aperture
is provided, through which passes a rod, wire, bar, or pin, grooved,
furrowed, or channelled on its external surface. This rod, wire, or pin
eaches up to or into the interior of the vessel or chamber through a

page_text: suitable guide block or surrounding picce, in which it may be held
preferably by a bent wire. The lubricating agent trickles down the
furrows or channels of the rod, bar, or pin on to the shaft, journal, or
other appliance to be lubricated, the above described arrangement
preventing such agent from being too rapidly supplied, but yet
maintaining its supply with due regularity.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charlas Henry Gardner in the Great Seal Patent
Office on the 1st December 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
HENRY GARDNER, of West Harding Street, Fetter Lane, in the City
of London, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of June, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-second
year of Her reign, did, for Herself, Her heirs and successors, give-and
grant unto me, the said Charles Henry Gardner, Her special licence that
I, the said Charles Henry Gardner, my executors, administrators, and
assigns, or such others as I, the said Charles Henry Gardner, my
exccutors, 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," upon the condition (amongst others) that I, the said Charles
Henry Garduer, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same 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 Charles Henry Gardner, do hereby

page_text: same is to be performed, to be particularly described and ascertained in
and by the following statement thereof, reference being had to the
accompanying Drawings, and to the letters and figures marked thereon,
that is to say :-
This Invention relates to an improved lubricator or apparatus for
lubricating.
My apparatus consists of a chamber, vessel, or receiver closed on
all sides, or nearly so, except at the bottom where a small aperture
is provided, through which passes a rod, wire, bar, or pin, grooved,
furrowed, or channelled on its external surface. This rod, wire, or pin
reaches up to or into the interior of the vessel or chamber through a
suitable guide block or surrounding piece in which it may be held
preferably by a bent wire. The lubricating agent trickles down the
furrows or channels of the rod, bar, or pin on to the shaft, journal, or
other appliance to be lubricated, the above described arrangement
preventing such agent from being too rapidly supplied, but yet
maintaining its supply with due regularity.
The accompanying Drawings exemplify a lubricator constructed
according to my Invention.
Figure 1 is an elevation, and Figure 2 a vertical section of the
lubricator.
A is a vessel or chamber which is closed at its lower end by a plug or cap
a which is fitted or fixed to this end; b is a passage formed through this
plug. In this passage b is fitted a grooved, furrowed, or channelled rod C.
Figure 3 is a transverse horizontal section of this rod. d, d, are curved
wires which pass through the rod, and rest on the top of the plug so as
to keep the rod C in place. The rod extends upward into the interior
of the chamber A, and descends below the bottom of the plug a. c, c,
are the furrows, grooves, or channels in the rod C. There is an air
hole in the chamber A. The chamber is filled with oil or other
lubricating fluid, which flows gradually and continuously down the
furrows or channels of the rod C on to the journal or axis or other
appliance to be lubricated. The rod thus acts as a guide rod to the
lubricating agent. The grooves, furrows, or channels c extend from
end to end of the rod C, that is to say, the whole length thereof.

page_text: Having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim, the
employment of a furrowed, grooved, or channelled rod in combination
with a vessel or chamber for holding lubricating material, substantially in
the manner and for the purpose described.
In witness whereof, I, the said Charles Henry Gardner, have here-
unto set my hand and scal, this Twenty-sixth day of November,
in the year of our Lord One thousand eight hundred and sixty-
nine
Witness,
M. HENRY,
68, Fleet St.,
London.
