Improvements in Lubricators.
I, EDUARD FRANKE, of Danzig, in the Kingdom of Prussia, in the German
Empire Engineer do hereby declare the nature of this invention to be as
follows:
:-
This invention relates to an improved lubricator in which a pump-piston
arranged within a rotating disk is used for sucking up oil from the oil-cup and
for pressing the oil into the steam-cylinder in equal quantities as well as in
perfectly regular intervals.
Said disk is contained within a hollow casing which is fixed to any suitable part
of the engine. The shaft of the disk extends horizontally through one side of the
casing, and carries a ratchet wheel which is intermittingly rotated by lever and
pawl in known manner by any moving part of the engine, thus intermittingly
rotating the disk itself. The convex surface of the disk is flattened at two
diagonally opposite parts, and a channel diagonally bored through the disk
Each end of
begins or terminates respectively at those flattened parts.
said channel is provided with a metal-ring, the holes in both the rings differing,
however, in diameter. A pump-piston having the diameter of the large hole is
inserted into the latter and has a projection extending through the small hole, thus
serving as guide for said piston. The length of the piston together with its
projection corresponds to the diameter of the rotating disk, and consequently the
ends of the piston project at both the flattened sides. As the diameter of the
casing is larger than that of the disk a space, which communicates with the oil-
reservoir, is formed between these parts, and thus is constantly filled with oil, said
reservoir being generally fixed directly to the top of the casing.
The pump-cylinder formed within the disk by means of the channel with its
rings communicates with the oil in the casing by means of a hole provided in that
side of the disk from which the shaft extends, and also the corresponding side of
the casing has two small channels, one of them for leading oil from the interior of
the casing into the pump during the sucking period, and the other for delivering
oil from the pump to the steam-cylinder during every forcing-period, both channels
being placed diagonally and in the same horizontal plane. On a level with the
said two small channels there is inserted into the curved side of the casing a rod
the inner and obliquely shaped, end of which extends into the casing so as to
displace the pump-piston twice during every rotation of the disk. Said rod may
be axially displaced by means of a female screw arranged outside the casing, and
having a scale on its periphery for indicating the position of the obliquely shaped
end. By such displacement of the rod the stroke of the pump and consequently
the quantity of oil pumped may be varied according to any requirement.
The new lubricator works as follows:
The disk together with its pump is intermittingly rotated by the above
mentioned lever-arrangement, and the pump-piston in pushing with its one end
against said rod displaced so as to suck oil into the pump-cylinder through the
small hole in the disk and through one of said small channels in the casing. Now,
as soon as the disk has made half a rotation, the pump-piston is again displaced
by its other end pushing against the rod, and the oil contained in the oil-pump is
forced into a pipe through said small hole in the disk and through the other small
channel, said pipe delivering the oil into the steam-cylinder.
A leather-collar is inserted between the disk and that side of the casing through
which the shaft extends, for the purpose of preventing any undue outflow of oil,

between the other side of the disk and casing.

Improvements in Lubricators.
I, EDUARD FRANKE, of Danzig, in the Kingdom of Prussia, German Empire,
do hereby declare the nature of my 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 an improved lubricator in which a pump-piston arranged
within a rotating disk is used for sucking up oil from the oil cup and for pressing
the oil into the steam-cylinder in equal quantities as well as in perfectly regular
intervals.
In order to make my invention clearer, I refer to the accompanying drawing in
which similar letters denote similar parts throughout the several views and in
which
Fig. 1 is a vertical longitudinal section through the lubricator, showing the pump-
piston in vertical position;
Fig. 2 is another vertical longitudinal section through the lubricator, showing the
pump-piston in horizontal position ;
Fig. 3 is a vertical cross-section, the piston being removed;
Fig. 4 is an upper-view, partly in elevation ;
Figs. 5 and 6 are details.
The disk a is contained within a hollow casing b which is fixed to any suitable
part of the engine. The shaft c of the disk a extends horizontally through one
side of the casing b, and carries a ratchet wheel d which is rotated by levere and
pawl in the ordinary manner by any moving part of the engine, thus rotating
disk a itself. The convex surface of the disk is flattened at the two opposite
parts and h, and a channel i bored through disk a begins or terminates
respectively at those flattened parts. Each end of said channel is provided with
a metal-ring k and 1, the holes in both the rings differing, however, in diameter.
A pump-piston m being of the same diameter as the large hole is inserted into
the latter, and has a projection n extending through the small hole, thus serving
as guide for said piston. The length of the piston together with its projection
corresponds to the diameter of the rotating disk, and consequently the ends of the
piston project at both the flattened sides g and . As the diameter of casing bis
larger than that of the disk, a space, which communicates with the oil-reservoir, is
formed between these parts, and thus is constantly filled with oil, said reservoir
being generally fixed directly to the top of the casing.
The pump cylinder formed within the disk by means of the channel i with its
rings and communicates with the oil in casing 6 by means of a hole o provided
in that side of the disk from which shaft c extends, and also the corresponding side
of the casing has two small channels and Figure 4, one of them p for leading
oil from the interior of the casing into the pump, during the sucking-operation,
and the other for delivering oil from the pump to the steam-cylinder during the
operation of forcing, both channels being in the same horizontal plane. On a level
with said two small channels p and there is inserted into the curved side of the
casing a rods, Figure 1, the inner and obliquely-shaped end of which extends into
the casing so as to displace the pump-piston m twice during every rotation of
disk a.
Said rods may be axially displaced by means of a female screw t arranged
outside the casing, and having a scale on its periphery for indicating the position
of the obliquely-shaped end. By such displacement of rod s the stroke of the

page_text: pump and consequently the quantity of oil pumped may be varied according to any
requirement.

The lubricator works as follows-Disk a together with its pump i k l m n is
intermittingly rotated by the above-mentioned lever-arrangement de f, and the
pump-piston in pushing with its one end against rod s is displaced so as to suck oil
into the pump cylinder through hole in disk a and through channel p in the
casing. Now as soon as disk a has made half a rotation, the piston m
is again displaced by its other end pushing against rod s, and the oil contained in
the pump is forced into channel r, said channel delivering the oil into the steam-
cylinder.
A leather-collar is inserted between disk a and that side of casing b, through
which shaft c extends, for the purpose of preventing any undue outflow of oil,
and the disk is pressed against the leather-collar by means of a spring to inserted
between the other side of the disk and the casing.
'
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
The combination of casing b communicating with the oil-reservoir, and of disk a
rotating within said casing with a pump im n being diagonally arranged within
disk a the piston m of said pump being intermittingly displaced during every
rotation of disk a by a projection or rod s secured to the casing, for the purpose as
described.
