Improvements in Lubricating Apparatus.
We, GEORG HUBER, of II Spaungasse No. 17, Vienna, Machinist, and SIMON
SIMOTTA, of XVIII Edelhofgasse, No. 19, Vienna, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
Lubricating apparatus of known construction operating in combination with
steam pressure for lubricating cylinders, slide valves, governors &c. are subject
to the inconvenience that the condensed steam or condensation water is obliged
to pass through the oil in order to come below the same and to force it upward,
whereby the oil becomes contaminated and heated by the water of condensation,
in addition the charge of oil in the lubricator cannot be entirely discharged.
The present invention has for its object to avoid the inconveniences mentioned
above, and consists in causing the condensation water to enter from below into
the oil-receptacle and thereby to raise the oil gradually without mixing therewith
and without heating the same. In addition, the consumption of the whole of
the oil is rendered possible, as also the regular drop-discharge thereof by a suit-
able drip pipe.
According to our invention we construct such lubricators as follows. An oil
cup provided with a nozzle at the lower end adapted to be screwed on to a steam
channel leading to the cylinder or other object to be lubricated has a charging
opening closed by a screw plug at the upper end. A passage is formed in the
lower end of the bottom nozzle that communicates with the said steam channel
but does not extend straight up into the oil cup, its upper part being formed with
two lateral branches situated above a regulating screw valve in the lower part.
The one branch is connected to an external tube that rises up to the upper part
of the oil cup where it is preferably first coiled one or more times round the latter
and then passed down again and connected with a passage leading into the bottom
of the oil cup. This tube acts as a condenser for the steam rising up from the
cylinder &c., the resulting condensation water being made to flow into the lower
part of the oil cup. A check valve is provided between the steam supply channel
and the condensing tube for preventing any of the condensation water from flowing
back into the former. The second above mentioned lateral branch of the steam
passage terminates in a socket in which is secured the lower end of a vertical glass
tube, the upper end of which is secured in a similar socket projecting laterally
from the upper part of the oil cup and having a passage extending up through it
there being a branch on the passage communicating with the interior of the oil
cup at its highest point just below the charging stopper. Into the vertical part
of the said passage in the upper socket is fitted firstly a small drip pipe extending
down into the glass tube and terminating in a small orifice, and secondly a regu-
lating screw plug that can be made to project more or less into the upper opening
of the drip-pipe and thus to regulate the discharge of a through it to the exact
extent required. The drip-pipe is by preference provided at its lower end with
a fine pointed stem which either enters the bottom orifice thereof or is arranged

page_text: at the side of it, so that the oil issuing from the drip pipe will flow down the said
stem to the fine point thereof whence it will fall in the form of drops, these being
visible through the glass tube. At the bottom of the lower socket of this sight-
feed device is a small discharge cock through which the contents of the glass tube
can be discharged at any time.
A similar discharge cock is provided laterally at the bottom of the oil cup, for
drawing off the contents thereof.
The action of the above described apparatus is as follows. The oil cup having
been filled with oil, steam is admitted from the steam cylinder casing or other
object into the external condensing coil; as the steam condenses in the latter, the
resulting water forced by the pressure into the lower end of the oil cup, and as
it rises therein it forces a corresponding quantity of oil out through the top
channel into the sight feed' apparatus, where it falls in drops from the drip pipe
into the lower end of the glass tube, whence it flows off through the before mentioned
lateral passage into the steam passage leading to the parts that require to be
lubricated.
Owing to the discharge channel being situated at the highest point of the oil
cup, the entire body of oil can be discharged therefrom.
For locomotive engines, a single such lubricator is made to serve for both steam
cylinders, by providing the sight drop feed device in duplicate, the channel lead-
ing from the top of the oil cup being made to branch off into each such branches
being provided with separate screw plug for regulating the discharge from each
sight feed to its respective cylinder:

Improvements in Lubricating Apparatus.
We, GEORG HUBER, of II Spaungasse No. 17, Vienna, Machinist, and SIMON
SIMOTTA, of XVIII Edelhofgasse, No. 19, Vienna, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
mment-
Lubricating apparatus of known construction operating in combination with
steam pressure for lubricating cylinders, slide valves, governors &c. are subject
to the inconvenience that the condensed steam or condensation water is obliged
to pass through the oil in order to come below the same and to force it upward,
whereby the oil becomes contaminated and heated by the water of condensation,
in addition the charge of oil in the lubricator cannot be entirely discharged.
The present invention has for its object to avoid the inconveniences mentioned
above, and consists in causing the condensation water to enter from below into
the oil-receptacle and thereby to raise the oil gradually without mixing therewith
and without heating the same. In addition, the consumption of the whole of
the oil is rendered possible, as also the regular drop-discharge thereof by a suit-
able drip-pipe.
According to our invention we construct such lubricators as we shall describe
referring to the accompanying drawings.
Figure 1 is a vertical section, Figure 2 is a side view partly in section, Figure 3
is an elevation partly sectional shewing a modification suited for a locomotive
and arranged for lubricating both cylinders.

page_text: Referring to Figures 1 and 2 A is the oil cup provided with a nozzle a at the
lower end adapted to be screwed on to a steam channel leading to the cylinder or
other object to be lubricated, and a charging opening closed by a screw plug bat
the upper end. A passage C is formed in the lower end of the
bottom nozzle that communicates with the said steam channel but
does
not extend straight up into the oil cup, its upper part being
formed with two lateral branches d and f situated above a regulating screw valve k
in the lower part having stem and hand wheel. The one branch d is connected
to an external tube g that rises up to the upper part of the oil cup where it is
preferably first coiled one or more times round the latter, and then passes down
again and is connected by union i with a passage g₁ leading into the bottom of the
oil cup. This tube acts as a condenser for the steam rising up from the cylinder
&c. the resulting condensation water being made to flow into the lower part of the
oil cup. A check valve m is provided between the steam supply channel and the
condensing tube for preventing any of the condensation water from flowing back
into the former. The lateral branch f of the steam passage terminates in a
socket in which is secured the lower end of a vertical glass tube h the upper
end of which is secured in a similar socket h¹ projecting laterally from the upper
part of the oil cup and having a passage extending up through it there being
branch n on the passage communicating with the interior of the oil cup at its
highest point, just below the charging stopper b. Into the vertical part of the said
passage in the upper socket h¹ is fitted firstly a small drip pipe extending down
into the glass tube and terminating in a small orifice r r¹ shewn to an enlarged
scale in Figures 4 and 5 and secondly a regulating screw-plug p that can be
made to project more or less into the upper opening of the drip-pipe and thus to
regulate the discharge of oil through it to the exact extent required.
a
The drip-pipe is by preference provided at its lower end with a fine pointed
stem which either enters the bottom orifice thereof as shewn in Figure 4 so as
to leave a lateral slot 1 on each side thereof or the drip pipe is formed as shewn
in Figure 5, so as to produce a lateral point r and an orifice r so that the oil
issuing from the drip pipe by rl will flow down the said stem to the fine point
thereof whence it will fall in the form of drops, these being visible through the
glass tube h. At the bottom of the lower socket h¹ of this sight feed device is a
small discharge cock through which the contents of the glass tube can be dis-
charged at any time. A similar discharge cocks is provided laterally at the
bottom of the oil cup, for drawing off the contents thereof.
The action of the above described apparatus is as follows. The oil cup having
been filled with oil, steam is admitted from the steam cylinder, casing, or other
object into the external condensing coil g; as the steam condenses in g, the result-
ing water is forced by the pressure into the lower end of the oil cup A and as it
rises therein it forces a corresponding quantity of oil out through the top channel n
into 'the sight feed apparatus h where it falls in drops from the drip pipe into the
lower end of the glass tube, whence it flows off through the lateral passage f into
the steam passage c leading to the parts that require to be lubricated.
Owing to the discharge channel n being situated at the highest point of the oil
cup, the entire body of oil can be discharged therefrom.
For locomotive engines, a single such lubricator is made to serve for both steam
cylinders, by providing as shewn in Figure 3 the sight drop feed device in dupli-
cate, the channel n leading from the top of the oil cup being made to branch off
into both, each branch being provided with a separate screw plug for regulating
the discharge from each sight feed to its respective cylinder.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
I. A steam lubricator composed of an oil receptacle, a steam condensing pipe
provided with a check valve and communicating with the receptacle at the bottom

page_text: thus raising the oil by condensed water, a small channel at the top of the recep-
tacle and a drip nozzle consisting of a small pipe provided with a lateral slot on
each side of a solid mandrel ending in a fine point, substantially as described.
2. In a steam lubricator an oil drip nozzle composed of a small channel, a small
pipe provided with a lateral opening and ending in a solid fine point enclosed in a
a sight glass, substantially as described.
