Complete Specification Left, 14th Dec., 1898-Accepted, 18th Mar., 1899
An Improved Arrangement for Lubricating Pistons and Piston Rods
in Steam Engine Cylinders.
I, GUSTAF FERDINAND MALMROS, of Sillgatan, No. 10, Göteborg, in the King-
dom of Sweden, Engine Driver, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object an improved means for simultaneously lubri-
cating pistons and piston rods of steam engine cylinders from a central lubricat-
ing apparatus.
It is shown in the accompanying drawings,
Figure being a section of the device together with the closing cover of a
steam engine cylinder and the stuffing box belonging thereto;
Figure 2 is an end view of the same; and
Figure 3 shows separate views of the stuffing box alone in section and end
elevation.
A lubricating pipe 1 leading from the central lubricating apparatus is con-
nected with a screwed socket or bush 2 by means of a simple screwed joint, the
said part 2 in turn being firmly screwed into the mass of the cylinder cover 3.
The above mentioned socket 2 does not entirely pass through the cover 3 but
leaves a narrow passage or channel 4 as a continuation of the lubricating passage
to the metal stuffing box 5, on the outer side of which an annular lubricating
channel is provided which lies directly under the mouth of the passage 4 and
thus communicates with the latter. One or more passages 7 lead to the interior
from said annular channel and connect the same with a second annular channel 8
on the inner side of the metal stuffing box. Lubricating passages 9 parallel
to the piston rods run from the passages 7 by means of which passages 9 the
lubricant can pass into the interior of the cylinder.
The lubricant blown through the lubricating pipe from the central lubricating
apparatus passes partially through the passage 7 into the lubricating channel 8
running around the piston rod, and partially through the passages 9, whereby
the lubrication of the pistons and piston rods is simultaneously effected. The
quantity of lubricant introduced may thus be easily regulated by the engine
driver with facility.

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention has for its object an improved means for simultaneously lubri-
cating pistons and piston rods of steam engine cylinders from a central lubricat-
ing apparatus.
It is shown in the drawings accompanying the Provisional Specification:
Figure 1 being a section of the device together with the closing cover of a
steam engine cylinder and the stuffing box belonging thereto;
Figure 2 is an end view of the same; and
Figure 3 shows separate views of the stuffing box alone in section and end
elevation.
A lubricating pipe 1 leading from the central lubricating apparatus is con-
nected with a screwed socket or bush 2 by means of a simple screwed joint, the
said part 2 in turn being firmly screwed into the mass of the cylinder cover 3.
The above mentioned socket 2 does not entirely pass through the cover 3, but
leaves a narrow passage or channel 4 as a continuation of the lubricating passage
to the metal stuffing box 5, on the outer side of which an annular lubricating
channel is provided which lies directly under the mouth of the passage 4 and
thus communicates with the latter. One or more passages 7 lead to the interior
from said annular channel and connect the same with a second annular channel 8
on the inner side of the metal stuffing box. Lubricating passages parallel
to the piston rods run from the passages 7 by means of which passages 9 the
lubricant can pass into the interior of the cylinder.
The lubricant blown through the lubricating pipe from the central lubricating
apparatus passes partially through the passage 7 into the lubricating channel 8
running around the piston rod, and partially through the passages 9, whereby
the lubrication of the pistons and piston rods is simultaneously effected. The
quantity of lubricant introduced may thus be easily regulated by the engine
driver.
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:
An arrangement for simultaneously lubricating pistons and piston rods of
steam engine cylinders from a central lubricating apparatus characterised by an
annular channel (6) being provided on the outer side of a stuffing box (5) located
inside the piston rod packing in the cylinder end, which channel is connected
with the central lubricating apparatus by means of a pipe or passage (1) passing
through the cylinder wall, and which annular channel communicates by means
of one or more passages (7) with a lubricating channel (8) in the stuffing box
running round the piston rod, from which passages (7) other passages (9) branch
off parallel to the piston rod and open into the cylinder, substantially as herein-
before set forth.
