An Improved Lubricator.
We, KARL ALBART JAKOBSON, of Christiania, Manufacturer, and THORVALD
RÖSTAD, of Moss, Agent, both in the Kingdom of Norway, 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 :-
Our invention relates to the construction of a lubricating apparatus in which the oil
is, by means of a plunger provided with a slide arrangement, sucked or drawn from
the oil-reservoir compressed in the pump cylinder and finally forced against the parts
of the machine to be lubricated.
In order to enable our invention to be fully understood we will describe how it can
be carried into effect by reference to the accompanying drawing, in wbich-
Figure 1 is a vertical section of a lubricator constructed according to our invention
and,
Figure 2 is a plan of the same.
In carrying out our invention the frame a, fastened by a flange 6 to the wall of the
place where the machine is located or to the machine itself, forms a cylinder of
varying diameters in which cylinder works a plunger e with a rod d and a slide e.
Through a channel f the oil flows directly down from the reservoir g into the cylinder
from which it is forced through a channel 4, a valve i and a pipe k to the parts of the
machine which are to be lubricated.
The plunger c with its rod d and slide e are so arranged, that the plunger c closes
the passage immediately before the slide e opens the passage h; in consequence of
the unequal diameters of the cylinder a, a compression is caused of the oil contained
in the cylinder and the oil being subjected to the pressure of the plunger is compressed
and effectually forced through the channel to the required places.
The valve is an ordinary spindle valve but is provided with a rubber ring i¹, as
shewn in Figure 1 of the drawing.
The plunger c is operated by means of a connecting rod / from the crank shaft m
working in the arms of the frame a, which crank shaft is by a ratchet wheel n, pawl o
and lever p driven by the machine.
As the apparatus works continually while the machine is at work it requires no
attention except to fill the reservoir with oil; in order to easily ascertain the
quantity of oil in the reservoir it may be made of glass and can be fixed on the
apparatus itself or in any other suitable place and is then connected with the apparatus
by a pipe.
If required the lubricator may be provided with two plungers and with two cranks
placed at an angle of 180° to each other, by which means a continual supply of oil to
the machine would be effected.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A lubricator having a cylinder a of varying diameters in which a plunger c
provided with a rod d and a slide e sucks or draws the oil from the reservoir 9,
compresses it in the cylinder a and finally forces it through the channel h, valve i and
pipe k to the places where the oil is to be used, substantially as set forth.
