IMPROVEMENTS IN AUTOMATIC LUBRICATORS
Year: 1870

page_text: LETTERS PATENT to Ernest Von Jeinsen, of the City and County of
San Francisco, State of California, United States of America,
Gentleman, for the Invention of "IMPROVEMENTS IN AUTOMATIC
LUBRICATORS."
PROVISIONAL SPECIFICATION left by the said Ernest Von Jeinsen
at the Office of the Commissioners of Patents, with his Petition,
on the 24th October 1870.
I, ERNEST VON JEINSEN, of the City and County of San Francisco,
State of California, United States of America, Gentleman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN AUTOMATIC
LUBRICATORS," to be as follows:-
My said Invention relates to a lubricator composed of a disc which
is fastened on the journal of the shaft to be lubricated in the interior

page_text: of the journal box, and which dips into an oil reservoir provided with a
mud box that is separated from the main compartment of the said
reservoir by a screen, so that the impurities accumulating in the said
mud box are prevented from coming in contact with the lubricating
disc. The oil, which may be carried out on the shaft beyond the journal,
is conducted back into the mud box through dripping channels in the
lower shell of the journal box, and after the impurities mixed with
such oil have become separated from the liquid, and have settled down
in the mud box, the clear oil passes up through the screen and is again
carried up on the journal. The journal box is provided with a cavity,
in which runs the disc. The lower part of the cavity forms the oil
reservoir, and as the shaft revolves the disc takes up a quantity of oil
and distributes the same on the journal of the shaft. The lower portion
of the oil reservoir forms the mud box which is separated from the
main compartment of the said reservoir by a screen of wire gauze or
other suitable material having its bearing upon suitable projections
formed with the lower box or shell, and otherwise attached to the same
in any suitable manner. This screen acts as a strainer to prevent any
mingling of the impurities which accumulate in the mud box with the
oil taken up by the disc. The lower shell of the box extends on both
sides a short distance beyond the journal, and it is provided with two
channels which extend down into the mud box, and terminate at points
outside of the journal. These channels are intended to receive the oil
which may be carried out on the shaft beyond the journal, and the
oil received in the said channels is carried back into the mud box
where the impurities mixed with it settle down while the pure oil passes
up through the screen and is again carried up by the disc. By this
arrangement the journal of the shaft can be lubricated without requiring
any attention for a long time and no oil is wasted. The mud box is
provided with a screw plug, so that it can be conveniently cleaned from
time to time.

filed by the said Ernest Von Jeinsen in the Great Seal Patent
Office on the 22nd April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ERNEST
VON JEINSEN, of the City and County of San Francisco, State of
California, United States of America, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of October, in the
year of our Lord One thousand cight hundred and seventy, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Ernest Von Jeinsen, Her
special licence that I, the said Ernest Von Jeinsen, my executors,
administrators, and assigns, or such others as I, the said Ernest Von
Jeinsen, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 Inven-.
tion for "IMPROVEMENTS IN AUTOMATIC LUBRICATORS," upon the condition
(amongst others) that I, the said Ernest Von Jeinsen, 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 Ernest Von Jeinsen, 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, reference being had to the accompanying,
Drawing forming a part of this Specification:-
My said Invention relates to a lubricator composed of a disc which
is fastened on the journal of the shaft to be lubricated in the interior
of the journal box, and which dips into an oil reservoir provided with.
a mud box that is separated from the main compartment of the said

page_text: reservoir by a screen, so that the impurities accumulating in the said
mud box are prevented from coming in contact with the lubricating
disc. The oil which may be carried out on the shaft beyond the journal
is conducted back into the mud box through dripping channels in the
lower shell of the journal box, and after the impurities mixed with such
oil have become separated from the liquid and have settled down in
the mud box the clear oil passes up through the screen and is again
carried up on the journal.
Figure 1 is a longitudinal vertical section of this Invention; Figure 2
is a transverse section of the same. The same letters indicate
corresponding parts in both Figures.
A designates a shaft which has its bearings in the box B; this box
is provided with a cavity a, in which runs a disc C on the shaft A, as
shown. The lower part of the cavity a forms an oil reservoir, and as
the shaft A revolves the disk C takes up a quantity of oil and distributes
the same on the journal of the shaft. The lower portion of the oil
reservoir forms the mud box 6 which is separated from the main com-
partment of said reservoir by a screen c of wire gauze or other suitable
material, having its bearing upon suitable projections formed with the
lower box or shell or otherwise attached to the same in any suitable
manner. This screen acts as a strainer to prevent any mingling of the
impurities which accumulate in the mud box (which is located beneath
the oil reservoir) with the oil taken up by the disc C. The lower shell
of the box extends on both sides a short distance beyond the journal,
and is provided with two channels & which extend down into the mud
box and terminate at points outside of the journal. These channels are
intended to receive the oil which may be carried out on the shaft beyond
the journal, and the oil received in the said channels is carried back
into the mud box, where the impurities mixed with it settle down
while the pure oil passes up through the screen c and is again carried
up by the disc C.
By this arrangement the journal of the shaft can be
lubricated without requiring any attention for a long time and no oil
is wasted. The mud box is provided with a screw plug, so that it can
be conveniently cleaned from time to time.

page_text: It is obvious that this Invention is applicable to journal boxes of
any description, and particularly to hangers supporting line shafts or
countershafts in mills or other factories.
Having thus fully described my said Invention I claim, the mud
5 box 6 formed in the lower shell of the box B located under the oil
reservoir a, and separated therefrom by a screen c, when combined
with the ducts d and disc C upon the shaft A, substantially as
described.
