PETER JENSEN, of 33, Chancery Lane in the County of Middlesex,
" IMPROVE-
MENTS IN STEAM LUBRICATORS," (A communication to me from abroad by John
Rudolph of Stockholm, Sweden)
The object of this Invention is to produce a lubricator for greasing the steam
passing through the steam cylinders and other internal frictional parts. It may be
placed upon the steam delivery pipe to the slide-box, upon the slide-box itself or
upon the cylinder and is arranged that it may be adjusted for more or less
abundant greasing, that is to say, that it permits the steam to take a required and
constant quantity of oil into the slide-box and the cylinder. Hereby a great
saving of oil is attained as compared with other methods of greasing, for instance
where, as in the ordinary grease cocks the oil is introduced directly into the
cylinder, and besides, this apparatus does not require such a careful attention as
others having once been adjusted for greasing with a certain decided quantity
of oil.
The lubricator consists of a pipe or hollow standard forming one piece with a cock
plug. On this plug is secured the body of the cock which is formed as an oil
reservoir. The required friction between the plug and its seat is produced by a hand
and by nut and check-nut. The oil reservoir which may be of any suitable shape
and material is provided with a funnel the mouth of which is closed by a stopper.
The bottom of the stopper is hollow and externally provided with threads to be
screwed into the inferior or lower opening of the funnel. There are holes in the
stoppers through the thread, which holes are closed, when the stopper is entirely
screwed in. There is a blow-through-valve for letting out the condensation water;
In lieu
this valve may also be used as a gauge-cock and is kept closed by a screw.
of this disposition a common cock with plug may be employed. That part of the oil

page_text: reservoir, which surrounds the cock-plug, is provided with a pipe which extends to
the inner side of the exterior wall of the oil reservoir. Opposite the end of this
pipe a stopper is screwed in the exterior wall of the oil reservoir. The cock plug
is provided with an upper opening communicating with the interior of the plug
and with the pipe connected therewith when the oil reservoir is turned in a
corresponding position. There is a screw for getting at the interior of the plug.
When the lubricator is wanted to be used the pipe or hollow standard is secured
on the steam pipe, the slide-box or the cylinder, so that the steam may penetrate
into, the hollow of the standard and the plug then the filling stopper is raised a
little so that oil may be poured into the funnel and so that the holes in the lower
part of same become free. Through these holes the oil will then flow down
into the reservoir. While this takes place the reservoir must be turned into such a
position that the pipe extending from the side of the plug casing comes opposite to
the stopper in the exterior wall of the reservoir. The gauge-cock must likewise
be kept closed. When the lubricator is to act the oil reservoir is turned round the
cock-plug so that the pipe extending from the plug casing is brought to occupy a
raised position, whereby its interior will communicate with the upper opening in
the plug. The oil above the level of the pipe mouth will then get down through
the pipe, the plug and the hollow standard, and follow the steam into the cylinder.
Instead of the consumed oil steam enters and becomes condensed to water, which
will sink down to the bottom of the oil reservoir, whereby a corresponding volume
of oil is displaced and made to get down through the pipe whence it is taken to
the cylinder by the steam. The apparatus is then greasing its minimum, as the
surface presenting itself to the condensation of the steam is then the least possible.
If the oil reservoir be turned further in the same direction, the level of the oil is
caused to sink, whereby the steam evidently must come in contact with a greater
surface of condensation (the interior side of the oil reservoir) the consequence of
which will be that more water is condensed, which in its turn must press out more
oil. If, on the other hand, the apparatus be adjusted so, that the pipe is turned
still further so as to occupy a horizontal position, the delivered quantity of oil will
evidently be the greatest possible. By means of trials and calculations a dial scale
may be made out, the hand indicating the degress, and according to which the
lubricator may be adjusted to deliver the requisite quantity of oil to the engine.
By means of the gauge-cock it may be seen how much water has collected in the
reservoir. The front side of the oil reservoir can also be provided with a plate of
glass in order to facilitate the inspection of the levels of the different liquids.
According to a modification of this apparatus the oil reservoir is stationary and
the plug to be turned. The plug being situated in the middle of the oil reservoir,
where it is maintained by means of a stuffing-box, is turned by a wheel secured to
the tail of the plug, which wheel is provided with a graduated circumference. At
the interior end of the plug and within the oil reservoir is the pipe by which the
interior of the oil reservoir is in communication with the interior of the plug, and
when this occupies a certain position, also with an eduction pipe and with the
steam pipe.
L
The operation of turning the lubricator for causing it to act is sometimes done
automatically at certain intervals, by connection with clockwork or by worm gear
connection with a moving part of the engine.

The object of this invention is to produce a lubricator for greasing the steam
passing through the steam cylinders and other internal frictional parts which
lubricator may be styled the Instillator." It may be placed upon the steam
delivery pipe to the slide box, upon the slide box itself or upon the cylinder, and is
so arranged that it may be adjusted for more or less abundant greasing that is to
say that it permits the steam to take a required and constant quantity of oil into
the slide-box and the cylinder. Hereby a great saving of oil is attained as
compared with other methods of greasing, for instance where as in the ordinary
grease cocks the oil is introduced directly into the cylinder and besides, this
apparatus does not require such a careful attention as others having once been
adjusted for greasing with a certain decided quantity of oil
Figure 1 is a front view, Figure 2 a side view, and Figure 3 a plan of the
Instillator. Figure 4 is a section on line a b Figure 2, and Figure 5 a section on
line c. d Figure 1.; Figure 6 is a vertical cross section of the Instillator in position
adjusted for greasing.
The lubricator consists of a pipe or hollow standard A forming one piece with
a cock plug B. On this plug is secured the body of the cock which is formed as
an oil reservoir C. The required friction between the plug and its seat is produced
by a hand D and by nut and check nut E screwed up against the top of the hand.
The oil reservoir C which may be of any suitable shape and material is provided
with a funnel F the mouth of which is closed by a stopper G. The bottom of the
stopper is hollow and externally provided with threads to be screwed into the
lower opening of the funnel F. There are holes H in the stopper through the
thread which holes are closed when the stopper is entirely screwed in. There is a
blow through valve I for letting out the condensation water, this valve may also
be used as a gauge-cock and is kept closed by a screw K. In lieu of this disposition
a common cock with plug may be employed. That part of the oil reservoir which
surrounds the cock plug B is provided with a pipe L which extends to the inner
side of the exterior wall of the oil reservoir. Opposite the end of this pipe a
stopper M is screwed in the exterior wall of the oil reservoir. The cock plug B is
provided with an upper opening N communicating with the interior of the plug
and with the pipe L connected therewith when the oil reservoir is turned in a
corresponding position. There is a screw O for getting at the interior of the plug B.
When the lubricator is wanted to be used the pipe or hollow standard A. is secured
on the steam pipe, the slide box or the cylinder, so that the steam may penetrate
into the hollow of the standard and the plug then the filling stopper G is raised a
little, so that oil may be poured into the funnel F and so that the holes H in the
lower part of same become free. Through these holes the oil will then flow down
into the reservoir C While this takes place the reservoir C must be turned into
such a position as shown at Figure 4 that the pipe L extending from the side of
the plug casing comes opposite to the stopper in the exterior wall of the reservoir.
The gauge cock I must likewise be kept closed. When the lubricator is to act the
oil reservoir is turned round the cock plug so that the pipe L extending from the
plug casing is brought to occupy a raised position, whereby its interior will com-
municate with the upper opening N in the plug. The oil above the level of the

page_text: "
pipe mouth will then get down through the pipe L, the plug B and the hollow
standard A and follow the steam into the cylinder. Instead of the consumed oil,
steam enters and becomes condensed to water, which will sink down to the bottom
of the oil reservoir whereby a corresponding volume of oil is displaced and made to
pass down through the pipe L whence it is taken to the cylinder by the steam.
The apparatus is then greasing its minimum, as the surface presenting itself
to the condensation of the steam is then the least possible. If the oil
reservoir be turned further in the same direction so that it for instance
is put in the position shown by Figure 6 the level of the oil is caused
to sink whereby the steam evidently must come in contact with a greater
surface of condensation (the interior side of the oil reservoir) the consequence
of which will be that more water is condensed which in its turn must press out
more oil.
If on the other hand the apparatus be adjusted so that the pipe L is
turned still further so as to occupy a horizontal position to the left, the delivered
quantity of oil will evidently be the greatest possible. By means of trials and
calculations a dial scale P may be made out (see Figure 1) the hand D indicating
the degrees and according to which the lubricator may be adjusted to deliver the
requisite quantity of oil to the engine. By means of the gauge-cock I it may be
seen how much water has collected in the reservoir which examination is effected
by turning thic apparatus in different positions and simultaneously opening the
cock I a little, when it will be seen if oil or water is getting out, by which
operation it may be judged how high the water stands and likewise if the oil be
consumed and consequently new filling be wanted. If it occasionally should be
necessary to grease with a greater quantity of oil than usual, this can easily be
effected by turning the reservoir to the right from the position shown in Figure 6
whereby the pipe L easily fills with oil which immediately passes down, as soon as
the oil reservoir is returned into the position Figure 6. By repeating this operation
any quantity of oil desired may be brought down. If the pipe L be very near the
vertical position a great quantity of oil may be rapidly got down by turning the
pipe in horizontal position to the left. The front side of the oil reservoir can also
be provided with a plate of glass in order to facilitate the inspection of the level
of the different liquids.
Figure 7 represents a modification of this apparatus where the oil reservoir Q is
stationary and the plug R to be turned. The plug being situated in the middle of
the oil reservoir where it is maintained by means of a stuffing box S is turned by
a wheel T secured to the tail of the plug which wheel is provided with a graduated
circumference. At the interior end of the plug and within the oil reservoir is the
pipe U by which the interior of the oil reservoir is in communication with the
interior of the plug and when this occupies a certain position also with an eduction
pipe V and with the steam pipe. From this description of the preceding apparatus
it, will be easily perceived that also this modified apparatus can be got to deliver
the required quantity of oil by turning the plug R by means of the wheel T so
that the pipe U attached to the plug is brought to occupy different positions by
which operation the oil level in the reservoir Q is caused to stand higher or lower
and consequently also the surface of condensation increased or diminished.
The operation of turning the lubricator for causing it to act is sometimes done
automatically at certain intervals by connection with clockwork or by worm gear
connection with a moving part of the engine.
And having thus described and ascertained- the nature of this invention and
the manner of carrying the same into effect as communicated to me I declare that
I claim:
First: The improved displacement lubricator consisting of a pipe shank or
hollow standard adapted for connecting to the part to be lubricated and. provided
with a cock plug with lateral aperture communicating with said pipe, in
combination with an oil reservoir so constructed as to form the case or body of the
cock and provided with a charging funnel, an eduction cock for condensed water,
and a pipe from the centre of the oil reservoir to within a little of the inner

page_text: circumference which pipe on turning the reservoir round can be put in or out
of communication with the interior of the cock plug and the part to be lubricated
and so as to regulate the supply of the lubricant thereto by varying the steam
condensing surface substantially as set forth.
Second: The improved displacement lubricator consisting of an oil reservoir so
constructed as to form the case or body of a cock and provided with a passage
from the plug of the said cock to the part to be lubricated and provided with a

pipe which when the plug is turned round as required puts the interior of the
reservoir in communication with the part to be lubricated and so as to regulate the
supply of the lubricant thereto by varying the steam condensing surface substan-
tially as set forth.
