IMPROVEMENTS LUBRICATORS
Year: 1869

page_text: LETTERS PATENT to Henry Green, of Preston, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS
LUBRICATORS."
Sealed the 27th May 1870, and dated the 21st December 1869.
PROVISIONAL SPECIFICATION left by the said Henry Green at the
Office of the Commissioners of Patents, with his Petition, on the
21st December 1869.
I, HENRY GREEN, of Preston, in the County of Lancaster, Engineer,.
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN LUBRICATORS," to be as follows:-
My Invention is applicable to lubricating the journals of horizontal or
diagonal shafts, and it consists in an improved self-acting combination
of parts for supplying oil or other lubricant to the journal.
In performing my Invention the lubricant is contained in a vesseÏ
or vessels attached to or cast to the bearing, and the lubricant is lifted
out of the vessel and supplied to the journal by a pulley or roller, the

page_text: upper surface of which is in contact with and is turned round by the
shaft to be lubricated. This pulley or roller is placed outside of the
bearing. The lubricant deposited on the shaft is scraped off by a lip
fixed to the bearing or step.placed in the required position for guiding
the lubricant to a channel communicating with the inside of the step.
The vessels for the lubricant at each end of the journal are connected
together by a pipe or other communication. The pulley or roller is or
may be supported on an eccentric shaft which is turned partly round
occasionally to keep it in contact with the shaft to be lubricated, or it
may be supported on a stud fixed to a weighted lever, or the axle
of the pulley or roller may be acted upon by a spring or springs.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Green in the Great Seal Patent Office
on the 1st June 1870.
I TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
GREEN, of Preston, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of December, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-third year
of Her reign, did for Herself, Her heirs and successors, give and grant unto
me, the said Henry Green, Her special licence, that I, the said
Henry Green, my executors, administrators, and assigns, or such
others as I, the said Henry Green, 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 "IMPROVEMENTS IN LUBRICATORS," upon the con-
dition (amongst others) that I, the said Henry Green, 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

page_text: Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Green, 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 statement (that is to say) :-
My Invention is applicable to lubricating the journals of horizontal
or diagonal shafts, and it consists in an improved self-acting com-
bination of parts for supplying oil or other lubricant to the journal.
In performing my Invention the lubricant is contained in a vessel
or vessels attached to or cast with the bearing, and the lubricant is
lifted out of the vessel and supplied to the journal by a pulley or roller,
the upper surface of which is in contact with and is turned round by
the shaft to be lubricated; this pulley or roller is placed outside of
the bearing. The lubricant deposited on the shaft is scraped off
by a lip fixed to the bearing or step placed in the required position
for guiding the lubricant to a channel communicating with the inside
of the step. The vessels for the lubricant at each end of the journal are
connected together by a pipe or other communication. The pulley or
roller is or may be supported on an eccentric shaft which is turned
partly round occasionally to keep it in contact with the shaft to be
lubricated, or it may be supported on a stud fixed to a weighted lever, or
the axle of the pulley may be acted upon by a spring or springs.
And in order that my Invention may be more fully understood and
readily carried into operation I will proceed to describe the accom-
panying Drawing, reference being had to the figures and letters marked
thereon.
Fig. 1 is an clevation, and Fig. 2, a plan of a pedestal to which my
improved lubricator is applied.
a is the shaft to be lubricated; b, the bearing or pedestal, to which
are cast or attached the vessels c containing oil or other lubricant; these
vessels c are connected by a hole d, or a single vessel may be made to
surround the pedestal. To the side of one of these vessels c is cast or
fixed a projection into which the stud e is rivetted or otherwise secured
(or the stud may be fixed in the pedestal), and on this stud is mounted
the weighted lever f, one end of which is forked and supports the pulley
or roller g, or the lever may be without fork, and the pulley or roller

page_text: would in that case project to one side. The pulley or roller is held in
contact with the shaft a, consequently, as the shaft a revolves it causes
the pulley or roller g to revolve also, and as the lower surface of the
roller or pulley 9 dips in the lubricant it is evident that a constant
supply is deposited on the shaft. The lubricant thus supplied to the
shaft is carried by the motion of the shaft or by capillary attraction
into the step of the pedestal; or the lip h may be fixed to the step to
scrape the lubricant off the axle and to guide it into the channel com-
municating with the inside of the step. The excess of lubricant supplied
to the shaft drops back into the vessels c; consequently there is no
waste, and the only attention required is to keep the vessels c supplied
with oil or other lubricant. In some cases it may be found desirable
to apply a roller or pulley g to each end of the step, and instead of
supporting the roller or pulley in a weighted lever it may be placed or
fixed on a pin or on an eccentric shaft which on being turned partly
round at intervals would keep the roller or pulley in contact with the
shaft to be lubricated, or a spring may be applied to press the roller or
pulley against the shaft.
Having thus stated the nature of my Invention, and described the
manner of performing the same, I declare that I claim the use of the
roller or pulley 9 placed outside of the bearing to be lubricated for
supplying the lubricant to the shaft.
In witness whereof, I, the said Henry Green, have hereto set my
hand and seal, this Thirtieth day of May One thousand eight
hundred and seventy.
