AN IMPROVED LUBRICATOR
Year: 1856

page_text: LETTERS PATENT to Thomas Dugdale, junior, of Blackburn, in the
County of Lancaster, Cotton Spinner, for the Invention of "AN IMPROVED
LUBRICATOR:"
Sealed the 3rd April 1857, and dated the 8th October 1856.
PROVISIONAL SPECIFICATION left by the said Thomas Dugdale at the
Office of the Commissioners of Patents, with his Petition, on the
8th October 1856.
I, THOMAS DUGDALE, junior, of Blackburn, in the. County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said Invention for" AN
IMPROVED LUBRICATOR," to be as follows:-
I make a small. vessel of any convenient shape, inside of which I fix a
small tube with a trough or mouth at the top of it, the said tube passing
through the vessel to the shaft to be oiled or lubricated. I pass a small shaft
horizontally through the vessel, with a wharf or pully outside to be.turned
by any convenient means. On this shaft (or, if more convenient, on another
shaft inside the vessel turned by a wheel and pinion from the first-mentioned
shaft) I place a metal ring, which revolves with the shaft, the bottom part of
the ring being in contact with the oil or lubricating matter, and as it revolves
scrapes against the edge of the trough or mouth, thus allowing a sufficient
quantity of the oil or other matter to pass down the tube to the shafting or
other substance to be lubricated. I fix the said apparatus in any convenient
position near the part to be oiled.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
DUGDALE, junior, of Blackburn, in the County of Lancaster, Cotton Spinner,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Eighth day of October, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Dugdale, junior, Her special licence that I, the said Thomas
Dugdale, junior, my executors, administrators, and assigns, or such others as
I, the said Thomas Dugdale, junior, 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; upon the condition (amongst others) that I, the said Thomas
Dugdale, junior; by an instrument in writing under my hand and seal, 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 Thomas Dugdale, junior, do hereby
declare the nature of the 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):-
My Invention consists in employing a vessel of any convenient size, or
material and shape, in the inside of which is placed a tube with a trough or
mouth at the top of it, the said tube passing through the vessel to the shaft
to be oiled or lubricated. I pass a shaft horizontally through the vessel with
a wharve or pulley outside, which with the shaft may be turned by any suit-
able means. This shaft, or another shaft driven by a pinion and wheel or
worm and wheel from the first-mentioned shaft, is furnished with a groove
or flanges, between which I place a ring or endless chain, which revolves with
the shaft, the lower part of the ring or endless chain being in contact with the
oil or lubricating matter; the trough is placed directly under the groove or
flanges, and does not touch the ring; the oil accumulates at the bottom of the '

page_text: groove or flanges until sufficient to make a drop, which enters the trough and
passes through the interior of the tube to the shaft to be oiled or lubricated,
or the trough or mouth may be so placed that as the ring or endless chain
revolves it scrapes against the edge of the said trough or mouth, thus allowing
a sufficient quantity of the oil or lubricating matter to pass down the tube
to the shafting or other substance to be lubricated. By employing rings or
endless chains of different thicknesses a greater or less supply of oil can be
given without changing the speed of the ring or endless chain, or taking off
the lubricator. One or more rings or endless chains are employed, according to
the size of the lubricator and the surface of the shafting or other substance
to be oiled, near which the lubricators are fixed in any convenient position.
These improvements will be clearly understood by reference to the accom-
panying Sheet of Drawings, with the figures and letters of reference thereon.
Fig. 1 is an elevation of a lubricator adapted for slow speeds, part of the
vessel being removed in order to represent the interior, and Fig. 2, a plan of
the same; Figs. 3 and 4 are elevations of a lubricator adapted for higher
speeds, also having part of the vessel removed; and Fig. 5, a plan of the
same.
In Figs. 1 and 2, a represents the vessel, through the lower part of which
is passed the tube b, which is fixed to the bearing of the shaft or other
substance to be lubricated; at the upper part of the tube is the trough or
mouth c. Through the vessel is placed the horizontal shaft d, driven by the
pulley e. Upon the shaft d are the flanges f, between which is the ring g, its
lower part being in the oil or lubricating matter h. As the ring revolves it
carries oil along with it, which accumulates in the flanges until sufficient for
a drop, which falls into the trough or mouth, and passes through the interior
of the tube to the shaft or substance to be lubricated.
In Figs. 3, 4, and 5, the vessel is shown at k, through which passes the
horizontal shaft furnished with the pinion m working into the toothed
wheel n upon the shaft o, causing it to revolve. Also upon the shaft o are
the flanges p, between which is the ring q, its lower part being immersed
in the oil or lubricating matter r, and its upper part pressing or scraping
against the trough or mouth 8 of the tube t. As the shaft o revolves, the
ring a moves with it, carrying oil or lubricating matter, which enters the
trough or mouths of the tube t, and passes through the interior u to the shaft
or other substance to be lubricated, or instead of the trough s, the form shewn
in Figs. 1 and 2 may be employed; it being understood that either the
dropping or scraping arrangement may be placed in the vessel, whatever be
the speed of the ring or rings, or endless chain or chains.

page_text: Having thus fully described the nature. of my said Invention, and the
manner in which the same is to be: performed, I desire it to be distinctly
understood that I do not confine myself to the exact details herein set forth,
as such. may be varied or modified without departing from, the principle
thereof; but. I claim the arrangement and construction of apparatus for
lubricating shafting or other similar materials, as herein described, and
illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Thomas Dugdale, junior, 'have hereunto
set my hand and seal, this Seventh day of April, in the year of our
Lord One thousand eight hundred and fifty-seven.
Signed, sealed, and delivered by the within-
named Thomas Dugdale, junior, in the
presence of
E. J. HUGHES,
Patent Agent,
Manchester.
