PROVISIONAL SPECIFICATION.
An Improved Automatic Lubricator for the Cylinders, Slides, and
Steam Passages of Steam Engines.
I, CAMILLE MEYER, of 20, Rue Custine, Paris, France, Draughtsman, do
hereby declare the nature of this invention to be as follows:-
My invention consists in the construction and arrangement of an automatic
lubricator which can be applied upon the steam pipes, slide boxes, and cylinders.
of any steam engine.
The operation of my invention is based on condensation and is carried out as
follows:
In Figure 1 the cock being open the steam passes into the lubricator and con-
denses in the upper part.
The water of condensation falls to the bottom of the reservoir by reason of its
density and steadily raises the level of the oil.
As the condensing surface of the apparatus is much too large in comparison with
the flow required, it will produce an excess of water which overflows into the
cylinder through the differential tube t at the same time as the oil, the flow of
which is according to the size of the orifice a.
Figure 2 is a detail view of the tube t shewing the orifice a.
It will be seen from the drawing that the level of the oil can only rise as high
as the line M N and that if the apparatus flows too much, it is necessary to mask
the orifice a by means of the hand wheel S on the top of the apparatus.
An index indicating the position of open or closed.
Figure 3 shows the apparatus furnished with a drop by drop indicator, the
function being identical with that described.
The drop passes into a glass tube filled with water and ascends through the
same.
Figure 4 shows the arrangement adopted in the case of engines which work or
travel alternately with the regulator opened and closed, such as locomotives for
example. In this case the differential tube t outlet is higher than the orifice
through which the oil flows, it follows that when the regulator is closed, the whole
of the stratum of oil M N m n which is stored can flow into the cylinder and
lubricate it.
The advantages of this invention are 1st that it is very simple. 2ndly it
requires no repairs. 3rdly the flow can be regulated and once regulated it remains
invariable whatever the external temperature may be.
This latter is the chief characteristic of my invention.

COMPLETE SPECIFICATION.
An Improved Automatic Lubricator for the Cylinders, Slides, and
Steam Passages of Steam Engines.
I, CAMILLE MEYER, of 20 Rue Custine, Paris, France, Draughtsman, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention consists in the construction and arrangement of an automatic.

page_text: lubricator which can be applied to the steam pipes, slide boxes, and cylinders of any
steam engine.
The operation of my invention is based on condensation and is carried out as
follows:
Fig. 1 is a sectional view of one form of my apparatus.
The cock R. is shown closed as regards communication between the oil and the.
steam space and an alternative passage through the cock is shown open whereby
the accumulated water resulting from the condensation of the steam is allowed to
escape at will when present in undue excess.
The cock R being opened to the steam space after the lubricator has been
charged with oil the steam will be condensed and will fall to the bottom of the
reservoir constantly raising the level of the oil.
As the condensing surface of the apparatus will condense more water than that
demanded for the proper flow of oil it will produce an excess of water which will
be discharged into the cylinder by the annular space between the tubes t. t. This
column of water between the said tubes is maintained in equilibrium for discharge
by the external mixed column of oil and water which by its lighter average density
will rise to the orifice of discharge-a-in-the-tube-t-slightly above-the-top-of-the
tube when the water and oil will be delivered to the steam space simultaneously.
When the accumulation of water is excessive it can be discharged as shown in
the drawing.
The feed of oil as shown in the drawing is at its maximum viz. when the
orifice is fully opposite to the orifice in t
To diminish the flow to any required extent or to zero it is only necessary
to turn the outer tube screwed on the tube t so as more or less to mask the
orifice-in-the-tube-t.
Fig. 2 shows an apparatus provided with sight drop by drop feed. The method
of operation remains the same.
The excess_of_water_of_condensation-escapes-by-the-single-tube-t. The-oil
escapes by the top of the tube b, but before passing to the cylinder or steam
space it follows the course indicated by the arrows. The drops of oil are visible
in a glass tube as they rise through the water with which it is filled.
Fig. 3 represents the arrangement adopted in the case of machines which have
alternative movements with the regulator open or closed for example locomotives.
In this case the differential tube t-has-its mouth at a higher level than the
orifice at which the oil escapes. It follows that when the regulator is closed all
the volume of oil between the lines M, N, m, n. which is there collected may
flow into the cylinder and lubricate it. The apparatus then operates in a con-
tinuous manner.
To prevent the water mingling with the oil a diaphragm E, F, is fitted in this
apparatus and a tube t' by which the oil can pass to the closed chamber.
Fig. 4 represents a spring suspended valve which it will be advisable to apply
between the cock R and the body of the lubricator in all cases in which the
lubricators are mounted on machines or engines where the regulator is frequently
opened and closed as for example on a locomotive.
This valve is part of my invention. It closes at the moment that the regulator
is shut and only opens again_when_the_pressure has fallen in the lubricator.lt
prevents the lubricator from emptying itself in consequence of the boiling of the
hot water which is set up as soon as the regulator admitting steam pressure is
closed.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The arrangement, and construction of an automatic lubricator with or
without automatic suspended self closing equilibrium valve applied to the cylinders,
valve chests, or steam pipes consisting of a reservoir containing oil fed by the

page_text: condensation of steam and in which the excess of condensed water has a distinct
outlet and the feed is regulated exactly whatever the exterior temperature may be.
2nd. The construction and arrangements of parts of an automatic lubricator
substantially as described and illustrated in the drawing hereto annexed.
