I PETER JENSEN Fel Inst PA of 33 Chancery Lane in the County of Middlesex
do hereby declare the nature of said invention for IMPROVEMENTS IN MECHANICALLY
WORKED LUBRICATORS FOR STEAM AND OTHER CYLINDERS (a communication to me
from abroad by the "Vulkan Stöberi og Mekanisk Verksted," Christiania Norway,
Iron founders and Engineers,) to be as follows:-
Lubricators constructed according to this invention belong to the class of
lubricators for steam and other cylinders which are worked from the engine to be
lubricated. It has heretofore been a defect in such constructions that the pressure
cylinder or other parts of the apparatus were easily damaged if the attendant
Deglected to stop the mechanism when the pressure ram had reached the end of its
stroke. By this invention therefore that defect is obviated and mainly by
automatically throwing out of gear the moving mechanism at the right moment.
These lubricators are also provided with a controlling appliance whereby the
attendant is always able to assure himself that the lubricator is in action.
The ram which forces the oil from its cylinder to the steam engine cylinder is
provided with a flange having a notch which works on a corresponding guide bar
on the framing so as to keep the ram from turning. To the ram is connected but
so as to turn freely in a recess therein a screw which by means of a nut mounted
in a boss on the framing serves to raise or lower tho screw and the ram. On the
nut is fixed a worm wheel. The nut is by a flange and by a screwed washer which
bears against the wormwheel prevented from moving endways. Into the worm
wheel is geared a worm provided with a pawl wheel which can receive intermittent
motion from a pawl on a lever which is worked up and down by the engine to be
lubricated. As the nut is thus turned the screw and the ram are forced down that
is to say when the screw is kept from turning which latter is attained by means of
a small feather inserted in a corresponding key way formed in a shoulder on the
screw, the said feather also fitting in a recess formed in the flange of the ram.
The feather or key is by a chain connected to an eye bolt fixed in the aforesaid
boss of the framing in which the nut has its bearing.

page_text: The disconnecting of the driving mechanism will thus take place by the dis-
connecting of the key and this latter will be effected as soon as the ram has come
nearly to the bottom of its cylinder because then the key will come in contact with
a nose or projection on a bracket fixed or formed on the cylinder, the consequence
being that the key is thrust out of its key way in the flange on the screw.
Immediately thereupon a shoulder on the screw comes in contact with the top of
the nut which latter will then carry the disconnected screw round with it and the
ram will stop in its downward path. In order to fill the ram cylinder with oil
again it is run back or out by means of a handle on the end of the screw and the
oil is then run in from a funnel.
The controlling appliance is arranged in the pipe conduit leading to the cylinder
to be lubricated. A box having a glass pane on two opposite sides and filled with
water is inserted in this conduit. In the bottom of this box when the pipe for the oil
enters a screw plug with a very fine cone point is inserted through a stuffing box
so as to enable the oil feed to be regulated as required. The oil will thus slide up
along the cone point and drop by drop rise up through the water so that the
engineer can observe the action. When the lubricator is being charged with oil
this aperture has to be closed to prevent the water from running into the ram
cylinder. Another plug at the top of the box serves to charge with water and to
enable the glass panes to be cleaned inside as required.

I PETER JENSEN Fel. Inst. P. A. of 33 Chancery Lane in the County of
Middlesex do hereby declare the nature of this invention (a communication to
me from abroad by the "Vulkan" Stöberi og Mechanisk Verksted, Christiania
Norway, Ironfounders and Engineers) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Lubricators constructed according to this invention belong to that class of
lubricators for steam and other cylinders which are worked from the engine to be
lubricated. It has heretofore been a defect in such constructions that the pressure
cylinder or other parts of the apparatus were easily damaged if the attendant
neglected to stop the mechanism when the pressure ram had reached the end of its
stroke. By this invention therefore that defect is obviated and mainly by auto-
matically throwing out of gear the moving mechanism at the right moment. These
lubricators are also provided with a controlling appliance whereby the attendant is
always able to assure himself that the lubricator is in action.
Figure 1 of the accompanying drawings represents the lubricator in sectional
elevation on line A B Figure 3. Figure 1b is a sectional elevation of part of tho
instrument. Figure 2 plan section on line C D Figure,1º. Figure 3 plan section
on line E F Figure 1, Figure 4 front view and Figure 5 plan section on line G H
Figure 4.
The ram a.which forces the oil from its cylinder 6 to the steam engine cylinder
is provided with a flange having a notch c which works on a corresponding guide
bar d¹ on the framing d so as to keep the ram from turning. To the ram is
connected but so as to turn freely in a recess therein a screw f which by means of
a nut mounted in a boss on the framing serves to raise or lower the screw and
the ram.
On the nut is fixed a worm wheel. The nut is by a flange and by a
screwed washer which bears against the worm wheel prevented from moving end-
ways. Into the worm wheel is geared a worm provided with a pawl wheel m which
can receive intermittent motion from a pawl n on a lever which is worked up and
down by the engine to be lubricated. As the nut is thus turned the screw and the
ram are forced down that is to say when the screw is kept from turning which
latter is attained by means of a small feather o inserted in a corresponding key way
formed in a shoulder on the screw, the said feather also fitting in a recess formed
in the flange of the ram. The feather or key is by a chain connected to an eyebolt
fixed in the aforesaid boss of the framing in which the nut has its bearing.
The disconnecting of the driving mechanism will thus take place by the
disconnecting of the key and this latter will be effected as soon as the ram has
come nearly to the bottom of its cylinder because then the key will come in
contact with a nose or projection on a bracket p fixed or formed on the cylinder,
the consequence being that the key is thrust out of its keyway in the flange on the
screw. Immediately thereupon a shoulder f' on the screw comes in contact with
the top of the nut which latter will then carry the disconnected screw round with

page_text: it and the ram will stop in its downward path. In order to fill the ram cylinder
with oil again it is run back or out by means of a handle h on the end of the screw
and the oil is then run in from a funnel v.
The controlling appliance is arranged in the pipe conduit leading to the cylinder
to be lubricated. A box s having a glass pane t on two opposite sides and filled
with water is inserted in this conduit. In the bottom of this box where the pipe ?
for the oil enters a screw plug q¹ with a very fine cone point q² is inserted through
a stuffing box so as to enable the oil feed to be regulated as required. The oil will
thus slide up along the cone point and drop by drop rise up through the water so
that the engineer can observe the action. When the lubricator is being charged
with oil this aperture has to be closed to prevent the water from running into the
ram cylinder. Another plug q³ at the top of the box serves to charge with water
and to enable the glass panes to be cleaned inside as required.
Having now particularly described and ascertained the nature of said invention
as communicated to me I declare that what I claim is
First. In mechanical lubricating apparatus for steam and other like cylinders,
the application of a feather or key o for coupling the plunger a and the screw f
together and of a bracket p for lifting off this coupling piece at the right time, and
of the collar or shoulder f for connecting the screw with its nut all for the purpose
of preventing the breakage of the machine.
Second. In the lubricating apparatus as hereinbefore firstly claimed the applica-
tion of the before described controlling apparatus operating in such a manner that
the oil on its way to the cylinder must pass through a transparent space charged
with water or other suitable fluid so that the engine driver can see it and obtains
facility for satisfying himself that the apparatus is in order substantially as set
forth.
Third. The combined arrangement of lubricator and controlling apparatus
connected therewith substantially as set forth.
