Improvements in and in connection with Lubricators.
I, HEINRICH GEORGE HELD, of Alinels, Holland, Engineer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in and in connection with lubricators and
has for its object to provide means whereby the oil, dripping from the bearing is
filtered in the dish or vessel which receives it and from hence it is readily conveyed
in a filtered slate into the oil hole in the bearing for re-use.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Figs. 1, 2, 3, 4, 5 & 7 are vertical cross sections of various forms of my improved
combined filter and lubricator detached and Figs. 6, 7, 8 & 9 side views showing the
same applied to a hanger.
In carrying out my invention and referring to Figs. 1 & 9, I employ below the
bearing a dish or vessel a of suitable shape and material, preferably of sheet tin, in
the middle of which I form a holo e and short tube b in connection therewith for the
reception of an ordinary lubricator c fastened to the dish or vessel a by means of a
spring g, or any other suitable means. In the dish or vessel a is employed a suitablo
piece of filter-cloth or paper i through which the oil in dripping from the bearing is
permitted to pass and make its way, in a filtered condition, through the hole e into
the lubricator c. When the lubricator c on the top of the bearing is empty, it is
changed with the one heneath the dish or vessel a which at that time is full of filtered
oil. The conveyance of the filtered oil into the oil hole of the bearing may be
performed mechanically in various ways.
Below the hole e, see Figs. 2 & 6, I form in connection therewith a horizontal
tube, one end of which is closed and the other open and adapted to receive a
pipe d, d' capable of swivelling in the pipe b', oach end d' of which is bent and carries
respectively above and below the hearing an ordinary lubricator c with a pin. The
oil in the dish or vessel a passes through the filter-cloth and the hole e and
pipes b&d into the pipe end d and lubricator e which is situated below the dish or
vessel a.
When the same is full of oil it is swivelled round to and thereby brought in
position over the bearing, while at the same time the empty one takes up its position
below the dish or vessel a.
In lieu of conveying the filtered oil from below into the oil hole of each bearing
separately as described, the filtered oil of a series of bearings may be conveyed from the
bottom to the top thereof by air, steam or water pressure. When employing air
pressure, see Figs. 3, 4 & 7, I employ in connection with the hole e a valve d³.
Beneath the dish or vessel a I form a short tube into which projects a pipe g' the
respective end of which is closed and opposite to the valve formed with an
opening e. The said tube is formed with a glass end c³ into which projects the
lower end of another pipe the upper end of which is in connection with the oil hole
in the bearing. The oil in dripping from the bearing passes through the filter-cloth i,
opening e into the glass end and when it is desired to raise and re-use the same,
compressed air is admitted through pipe g' into the same, which closes the valve d³
through opening e¹ and forces the filtered oil through the pipe h into the oil hole of
the bearing. In lieu of passing the pipe / around the side of the dish or vessel a, the
same may be passed through the same into the tube & and glass end c³.
To facilitate the raising of the filtered oil by steam or water pressure, the dish or
vessel a below the opening and valve I form with a cylinder B, see Figs. 5 & 8,
having an oil outlet pipe and a steam or water inlet pipe 9' formed respectively
E

page_text: near the top and bottom thereof. The upper end of the oil pipe is furnished
with an ordinary lubricator e in connection with the oil hole in the bearing and
the cylinder B with a piston hend. The filtered oil which has passed through the
hole and valve d' accumulates on the top of the piston head and is forced, by the
pressure of steam or water acting on the same, through the pipo k into the oil hole of
the bearing, the valve being closed by the pressure of oil.
The air, steam or water pipes g' & described, of a series of bearings are
connected together so as to permit of raising the oil of the same simultaneously
by means of a suitable pump connected therewith.
In lieu of actuating the piston head by steam or water pressure, the same way
be operated by hand by furnishing it with a rod y and bringing it under the
influence of a spring 9ª, seo Fig. 7", and the oil thereby raised in a similar manner as
hereinbefore described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed. I declare that what I
claim, is :-
"In automatic filters and lubricators combined."
1st. A dish or vessel a having an opening employed below the bearing and
containing a filter-cloth or paper through which the oil, in dripping from the
bearing, passes in combination with a lubricator e in communication with the
opening, substantially as and for the purpose set forth with reference to
Figs. 1 & 2.
2nd. The dish or vessul a containing a filter-cloth or paper and having an
opening e and valve d³ in combination with a receptacle &, or B, formed below the
same with air, steam or water inlet pipe g', ' and above with an oil outlet pipe h,
adapted to raise the filtered oil into the oil holes of a series of bearings, by the action
of a pump, substantially as set forth with reference to Figs. 3, 4 & 5."
Dated this oth day of September 1050.
