CERTAIN IMPROVEMENTS IN APPARATUS FOR LUBRICATING MACHINERY
Year: 1854

page_text: LETTERS PATENT to Adolphe Mohler, Manufacturer, of Obernay, Bas
Rhin, in the French Empire, for the Invention of "CERTAIN IMPROVEMENTS
IN APPARATUS FOR LUBRICATING MACHINERY."
PROVISIONAL SPECIFICATION left by the said Adolphe Mohler at the,
Office of the Commissioners of Patents, with his Petition, on the 2nd
February 1854.
I, ADOLPHE MOULER, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN APPARATUS FOR LUBRICATING MACHINERY" to be
as follows:-
For vertical or inclined shafts or spindles, I employ a short fixed' spindle or
stud, fixed in a cup or reservoir of oil.
1
A tube or socket, formed at or attached to, the end of the revolving shaft.or:
spindle, is fitted on the fixed stud, round which it turns freely and rests upon
the bottom of the oil cup. A few notches may be made in; the lower end of,
the tube to facilitate the entrance of the oil, which ascends between the tube
and the fixed stud when the tube is revolving. The tube may be prevented,
from rising by means of a screw passing through' it and entering a groove in

page_text: the stud or otherwise. I form a passage in or at the side of the fixed stud, so
that there may be a circulation of the oil between the tube and the stud.
A disc, with grooves in it, may be attached to the revolving tube, to assist in
raising the oil.
For horizontal shafts or spindles I employ the fixed stud and tube, and I
apply a disc at the end of the tube, which runs close to the end of the box
which supports the stud. Perforations are made in the tube to allow the oil
to flow back into the reservoir. For intermediate bearings of shafts I attach
a disc to the shaft, which disc is fitted into and runs in a groove or recess
in the bearing, and dips into a reservoir or cup of oil so placed as to receive
the oil which escapes and drops from each end of the bearing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Adolphe Mohler in the Great Seal Patent Office on the
24th July 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPHE
MOHLER, Manufacturer, of Obernay, (Bas Rhin,) in the French Empire, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of February, in the year of our Lord One
thousand eight hundred and fifty-four, in the seventeenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said.
Adolphe Mohler, Her special licence that I, the said Adolphe Mohler, my
executors, administrators, and assigns, or such others as I, the said Adolphe
Mohler, 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 "CERTAIN IMPROVEMENTS IN APPA-
RATUS FOR LUBRICATING MACHINERY," upon the condition (amongst others) that
I, the said Adolphe Mohler, 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.

page_text: NOW KNOW YE, that I, the said Adolphe Mohler, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawing, and to
the figures and letters marked thereon, that it is to say:-
I construct apparatus for lubricating machinery in such manner that the
lubricating liquid is raised and brought in contact with the rubbing surfaces by
capillary attraction in conjunction with the motion of the moving parts.
Figure 1 of the accompanying Drawing is a vertical section of the bearing of
a vertical spindle or shaft provided with my improved lubricating apparatus.
a is a box or cup containing oil, and provided with a cover b; c is a fixed
cylindrical pin or stud on which is fitted the collar or socket d, which forms the
lower end of the vertical shaft or spindle; e is a pulley for giving motion to
the spindle, which may, however, be driven by any other suitable means; f is
a screw pin, which enters a notch or groove in the stud c, and prevents the
collar d from rising up on the stud. The revolution of the collar d, and the
capillary attraction between the collar and stud c, cause the oil to ascend and
descend between the collar and the stud, and these parts are thus kept con-
stantly bathed with oil. To facilitate the flow of the oil, the bottom of the
collar d may be furnished with notches l, which are also shewn in Figure 5,
which is a plan of the bottom of the collar d. The flow or circulation of the
oil may be still farther facilitated by forming a passage down the centre of the
stud c, with a lateral aperture into the oil cup, as shewn at g, in Figure 2,
which is a section of an arrangement in other respects similar to Figure 1.
Figure 6 is a sectional plan of the stud and collar shewn in Figure 2. In
lieu of forming the passage in the interior of the stud, as in Figures 2 and 6,
it may consist of a groove in the side of the stud, as shewn at h in the vertical
section, Figure 36, and sectional plan, Figure 7; or it may be simply a flat on
the side of the stud, as shewn in the sectional plan, Figure 8. A groove may
be formed in the oil cup in connection with the groove or passage in the stud,
as shewn at k in Figure 9, which is a plan of the oil cup a. In Figure 3,
the collar d is prevented from rising by a small collar fixed on the stud c, by
a screw f. The collar d is here shewn with a screw cut on its exterior for
affixing a pulley or wheel, and it is evident that its form may be varied
according to the purpose for which it is required. Figure 4 is a vertical
section, and Figure 10 is a plan shewing a disc i with grooves j attached to
the bottom of the collar d. The object of this disc is still further to facilitate
or accelerate the flow or circulation of the oil. Figure 11 is a vertical section

page_text: of a portion of a horizontal shaft with the improved lubricating apparatus.
The shaft terminates in a socket or collar d, as in Figure 1, which is furnished
with a disc m, dipping into the oil in the box a, and running in contact or
close proximity with one of the sides n of the oil cup; c is the fixed stud which
fits into the collar d, and is firmly fixed to the box a. The oil is raised by the
capillary attraction between the disc and the side n of the box, assisted by the
motion of the disc, and it passes along the stud c and the interior of the
collar d, whence it escapes at the aperture p, and again falls into the box a.
Figure 12 is a vertical section, and Figure 13 is a horizontal section of another
arrangement for lubricating a horizontal shaft. is the horizontal shaft which
carries a disc m, working in a cavity or chamber in the bearing s, and dipping
into the oil cup a. The oil is raised by the capillary attraction between the
disc m and the sides of the chamber in the bearings, assisted by the motion
of the disc. The oil passes along the shaft and falls again into the oil cup;
t, t, are grooves turned in the shaft r, to prevent the oil from travelling along
the shaft beyond the oil cup. The disc m may have curved grooves in the
sides, as shewn in the side view, Figure 14, to enable it to raise the oil in
greater quantity. Its edge may be plain or serrated, as shewn in Figure 14.
I have described the different arrangements for vertical and horizontal shafts,
but the lubricating apparatus may also be applied to inclined shafts, and the
particular arrangement best adapted for any particular case will depend on the
inclination of the shaft and the other circumstances of the case.
Having now described the nature of the Invention, and in what manner
the same is to be performed, I wish it to be understood that I do not
claim generally the constructing spindles with sockets or collars turning upon
fixed pins, nor do I claim generally the application of a disc attached to a
shaft or spindle and dipping in oil for the purpose of lubrication; but what
I claim is,-
Firstly, the constructing lubricating apparatus with a collar or socket
turning on a fixed pin or stud, and arranged in connection with an oil cup in
the mode or modes herein-before described in reference to Figures 1, 2, 3, 4,
5, 6, 7, 8, 9, and 10.
Secondly, the constructing lubricating apparatus with a collar or socket
turning on a fixed pin or stud, and furnished with a disc, running in contact
or in close proximity with a fixed surface, and dipping in the oil or lubricating
liquid, which is raised by capillary attraction assisted by the motion of the
disc, as herein-before described in reference to Figure 11.
Thirdly, the constructing lubricating apparatus with a disc fixed on a

page_text: revolving spindle or shaft, and dipping into the lubricating liquid and running
in close proximity with a fixed surface or two fixed surfaces, as herein-before
described in reference to Figures 12 and 13.
In witness whereof, I, the said Adolphe Mohler, have hereunto set my
hand and seal, this Fourteenth day of July, in the year of our Lord
One thousand eight hundred and fifty-four.
