I PETER JENSEN of 33 Chancery Lane in the County of Middlesex do hereby
declare the nature of said invention for "IMPROVEMENTS
IN AUTOMATIC OR
MECHANICALLY WORKED APPARATUS FOR LUBRICATING INTERNAL PARTS OF ENGINES
OR MACHINERY EXPOSED TO HIGH PRESSURE STEAM OR OTHER FLUID" (A com-
munication to me from abroad by Lars Christian Nielsen of Copenhagen Denmark
Engineer) to be as follows:-
This invention consists in an improved automatic high pressure lubricator which
lubricates such parts of machinery which work in a space where the air or steain
pressure is higher than the ordinary atmospheric pressure for instance slide valves
and pistons.
The apparatus consists of a sliding pump barrel which can move backwards and
forwards within certain limits, alternately either impelled by its own plunger or
by itself in such manner that the oil is drawn in when the pump barrel is in one of
its end positions, while the oil is forced out in its other end position, friction being
used as a means for accomplishing, that at each change of motion the plunger
takes so great a part of the stroke as it is to have, whereupon the pump itself is
put in motion and accomplishes the remainder of the stroke.
The apparatus consists mainly of the fixed framework and the pump which is
arranged lengthways between two arms of a bow which by an eccentric is moved
backwards and forwards. To the forward arm the pump plunger is connected and
is drawn out when set in motion. The pump then sucks oil in through a lateral
port when it is open to a corresponding rear port arranged in the framing and
leading to the oil supply reservoir. The plunger however only goes out so far
until an adjustable stop or screw in the rear arm of the bow comes into contact
with the end of the pump itself. As soon as that occurs and the bow still moves
a little further forward the hind arm of the bow pushes the whole pump with it,
until the port in the side of the pump comes opposite to a port which leads to the
space into which the oil is to be pumped. The pump can slide steam tight on a
flat fall of the frame containing the ports.

page_text: When the direction of the movement of the bow changes the first thing that
happens is that the plunger is pressed into the pump and the sucked in oil is
driven out into the port until the plunger strikes against the bottom of the pump
when the pump is driven back again and the same working occurs again.
It will be seen that in order that the working should take place as described the
pump must have a greater resistance against motion on the flat fall, than the
resistance which the plunger has to overcome. This can be easily obtained by
pressing a plate which has a certain amount of spring against the backside of the
pump by means of screws.
The moving mechanism of the bow consists of an eccentric which by suitable
connections is connected to some moving part of the engine which is to be
lubricated. The lubrication may be regulated in two ways. The cruder way
consists in varying the speed of the apparatus, whilst the more delicate mode
consists in altering the length of the plunger's stroke by means of the adjustable
.stop screw in the rear arm of the bow, and thereby altering the amount of oil
pumped per stroke. It is clear that at the same time the port in the frame must
be made so wide that the working will be the same although the stroke may be
made a little shorter or longer.
The form of the bow may be modified in many different ways, for instance so
that the eccentric is situated at the end of the pump instead of under same, or it

(a Communication to me from abroad by Lars Christian Nielsen of Copenhagen
Denmark Engineer) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :—
This invention consists in an improved automatic high pressure lubricator which
lubricates such parts of machinery which work in a space where the air or steam
pressure is higher than the ordinary atmospheric pressure for instance slide valves
and pistons.
The apparatus consists of a sliding pump barrel which can move backwards and
forwards within certain limits, alternately either impelled by its own plunger or by
itself in such manner that the oil is drawn in when the pump barrel is in one of
its end positions, while the oil is forced out in its other end position friction being
used as a means for accomplishing that at each change of motion the plunger takes
so great a part of the stroke as it is to have whereupon the pump itself is put in
motion and accomplishes the remainder of the stroke.
In the accompanying drawings Figure 1 is a side view of an apparatus constructed
according to this Invention. Figure shows the lower part of the apparatus with
the cover removed and the moving parts in section and Figure 3 is a plan section
on line A B Figure 2. The mode of action will be best understood by reference to
Figures 2 and 3.
The apparatus consists mainly of the fixed framework S and the pump p which
is arranged lengthways between two arms b₁ and b₂ of a bow which by an
eccentric e on the axle a is moved backwards and forwards. To the forward arm b₁
the pump plungern is connected and is drawn out when set in motion in the
direction of the arrow and the pump p takes the position shown in the Figures.
The pump then sucks oil in through a lateral port 7, (Figure 3) when it is open to
a corresponding rear port r, arranged in the framing and leading to the oil supply
pipe and reservoir O (Figure 1). The plunger however only goes out so far until
the adjustable stop or screw m in the rear arm b₂ of the bow comes into contact
with the end of the pump p itself. As soon as that occurs and the bow still noves
a little further forward in the direction of the arrow the stop m on the hind arm
of the bow pushes the whole pump p with it, until the port r, in the side of the
pump comes opposite to a port 2 which by the delivery pipe i leads to the space
into which the oil is to be pumped. The pump can slide steamtight on flat face g
of the frame S containing the ports r₁₂
When the direction of the movement of the bow changes the first thing that
happens is that the plunger n is pressed into the pump p and the sucked-in oil is
driven out into the port r₂ until the plunger n strikes against the bottom of the
pumpp when the pump is driven back again until the position is reached as shown
n the drawing and the same working occurs again.
It will be seen that in order that the working should take place as described the
pump must have a greater resistance against motion on the flat face g than the
resistance which the plunger has to overcome. This can be easily obtained by
pressing the front plate f, which has a certain amount of spring, against the back
ide of the pump by means of say four screws.

page_text: The moving mechanism of the bow consists, as shown in the accompanying
drawings of an eccentric e which by suitable connections is connected to some
moving part of the engine which is to be lubricated. The lubrication may be
regulated in two ways. The cruder way consists in varying the speed of the
apparatus, while the more delicate mode consists in altering the length of the
plunger's stroke by means of the adjustable stop screw m in the rear arm b₂ of the
bow, and thereby altering the amount of oil pumped per stroke. It is clear that
at the same time the ports r, and r, in the frame inust be made so wide that the
working will be the same although the stroke may be made a little shorter or
longer.
The form of the bow may be modified in many different ways, for instance
so that the eccentric is situated at the end of the pump instead of under saine, or
it may be connected to a crank, in short, any suitable means may be used which
will produce a backward and forward motion, without altering the nature of the
invention. In like manner the reservoir may be of any form, or it may be left out
altogether and the pump inay be provided with a pipe leading to a cask of oil so
that the apparatus can supply itself, the cask may also be placed on a lower level
than the apparatus so that the oil is sucked up.
Having now particularly described and ascertained the nature of said invention
and in what manner the same is to be performed I declare that what I claim as
the invention communicated to me is :-
First-Apparatus for pumping oil or other liquids by means of a pump with
piston, in such manner that the liquid inlet to and outlet from the pump take place
through the same hole in the pump, such hole terminating in a face on the outside
of the pump which face fits liquid tight against another face and can slide against
it, the whole pump being moved so that the said hole alternately comes against the
outlets for the suction pipe and delivery pipe.
Second-Apparatus for pumping oil or other liquids having such an action;
that the suction and delivery actions take place by the movement of a piston in a
pump while the distribution of the liquid is accomplished by the shifting of the
pump itself into various positions.
Third Apparatus for pumping oil or other liquids by a pump with piston in
such manner that both the pump and the piston are alternately moved, and so
that their respective movements can be apportioned to them in different ways by
the adjustment of the apparatus according to the amount of liquid desired to be
pumped in per stroke.
Fourth-The application of friction as a means for attaining that each time the
direction of motion changes, the piston first takes as long a part of the stroke as it
is to have, and then the pump itself is set in motion and accomplishes the remainder
of the stroke.
Fifth-The adjustment of the piston stroke by the screw, m in the bow
arm b₂.
Sixth-
-The construction of lubricating apparatus as shown in the drawings.
