Year: 1867

page_text: LETTERS PATENT to Samuel Lynes, of Burley, near Leeds, in the County
of York, for the Invention of "AN IMPROVED SELF-ACTING LUBRICATOR."
I
PROVISIONAL SPECIFICATION left by the said Samuel Lynes at the
Office of the Commissioners of Patents, with his Petition, on the
22nd August 1867.
I, SAMUEL LYNES, of Burley, near Leeds, in the County of York, do hereby
declare the nature of the said Invention for "AN IMPROVED SELF-ACTING
LUBRICATOR," to be as follows:-
My Invention has for its object the lubricating of the necks or bearings of
shafting by a simple and self-feeding method which economizes the use of
oil and dispenses with such constant attendance. In proximity to the neck.
of a shaft I affix to the bracket carrying the same a smaller bracket; by means
of which I support 'two small rollers, one above the other, the lower one.
having a groove cut in its centre in the circle of its rotation and receiving
motion through a grooved pulley on its axis by means of a band driven by the
shaft to be lubricated; pinion wheels are secured to the axes of both rollers,
consequently the lower one drives the upper one: An oil feeder and receiver
is placed under the neck into which a supply of oil is poured and by means

page_text: of a band made of cotton or other absorbent substance and passing between
the two rollers named and around a friction roller placed in the bottom of the
oil receiver the oil is carried upwards, and being squeezed out between the
rollers falls into a spout placed underneath them and is conducted to the
neck. By this means the oil is kept in constant circulation, as it no sooner
drops from the neck of the shaft into the receiver than it is again carried
upwards upon coming in contact with the band.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
the said Samuel Lynes in the Great Seal Patent Office on the
19th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
LINES, of Burley, near Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of August, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign did, for Herself, Her heirs and successors, give and grant unto me,
the said Samuel Lynes, Her special licence that I, the said Samuel Lynes,
my executors, administrators, and assigns, or such others as I, the said
Samuel Lynes, 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 SELF-
ACTING LUBRICATOR," upon the condition. (amongst others) that I, the said
Samuel Lynes,, 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 Samuel, Lynes, 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
thereof, that is to say:
My Invention has for its object the lubricating of the necks or bearings of
shafting by a simple and self-feeding method which economizes the use of oil

page_text: and dispenses with such constant attendance. In proximity to the neck of a
shaft I affix to the bracket carrying the same a smaller bracket, by means of
which I support two small rollers, one above the other, the lower one having
a groove cut in its centre in the circle of its rotation, and receiving motion
through a grooved pulley on its axis by means of a band of cotton tow; india-
rubber, or other suitable substance driven by the shaft to be lubricated..
Pinion wheels are secured to the axis of both rollers, consequently the lower
one drives the upper one. An oil feeder and receiver is placed under the neck,
into which a supply of oil is poured, and by means of a band made of cotton
or other suitable substance and passing between the two rollers named, and
around a friction roller placed in the bottom of the oil receiver the oil is
carried upwards, and being squeezed out between the rollers falls into a spout
placed underneath them and is conducted to the neck. By this means the oil
is kept in constant circulation, as it no sooner drops from the neck of the shaft
into the receiver than it is again carried: upwards upon coming in' contact
with the band. In some instances I dispense with the use of pinions, simply
using a light upper roller.
A modified arrangement of my Invention; more especially adapted to high
speeds of shafting, consists in the use of a small metal chain (in lieu of a band
of cotton) which is driven over grooved pulleys in the oil receiver, and carried
upwards some few inches when it passes over a friction roller perforatedi with
holes which communicate. with a hole in the axis consisting of a pipe. This
latter conveys the lubricant carried up by the chain to the neck of the shaft.
In order, however, that my Invention may the better understood, reference
is made to the accompanying Sheet of Drawings, and to the letters and figures
Figure 1 is a front elevation, and Figure 2 a side elevation of my first-
named arrangement where cotton or other substitutes are used.
A is a bracket secured to any convenient part near the bearing to be lubri-
cated. The lower part of the bracket is of a cup formation, as seen in the
sectional plan Figure 3, and in communication with the pipe B by which
the oil or other lubricating substance is conveyed to the neck of the shaft to
which it is applied; C is the grooved pulley driven by a band from the main
shaft and keyed upon the lower shaft c (which is grooved. and nicked, as will
be seen on reference to Figure. 2); c' is the small upper roller, in this case
rotated by the friction of the band 2, which extends into the trough D and
passes round the small friction pulleys d, d', being kept in the requisite state

of tension by means of the rod E, the upper end of which screws into a lug or
projection on the bracket A. D' is simply a hollow projection from the
receiver D through which a bolt may be passed to secure the receiver to the
bottom of a hanging bracket. The band carrying oil upwards it is more or
less squeezed out between the rollers c and c¹ and falls into the cup or trough
of the bracket A, and is there conveyed by the pipe B to the neck of the shaft.
Figures 4 and 5 are transverse and longitudinal sections of my modified
arrangement, Figure 6 being a plan of the same. A is a grooved pulley
driven by a band from the shaft, and keyed upon the shaft a in the oil or
lubricating trough B. a' is a small roller (forming part of the shaft a) grooved
so as to adapt it to receive the links of the chain a³, which is driven by it
and passes under the friction pulley 6 and thence over the perforated pulley c,
returning under the pulley 61 to the roller a¹. The oil or other lubricant
carried upwards by the chain percolates through the pulley c into the pipe C,
and is thus conveyed to the neck or bearing requiring lubrication, any surplus
oil or lubricant falling into the receiver B and being re-used., Gauze wire
may be placed over the receivers to keep out dirt, and a metal case D used
with a cap for the top, if desired, for a like purpose.
b
For each of the above-named apparatus fluid lubricants only can be used.
Having now fully described and ascertained the nature of my Invention,
and in what manner the same may be performed, I wish it to be understood
that what I claim as and of my Invention is self-acting lubricators constructed
essentially in the manner shown and described, without' confining myself to
the precise details shown.
In witness whereof, I, the said Samuel Lynes, Have hereunto set my
hand and seal, this Eighteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-eight.
