Improved Means of and Apparatus for Lubricating.
I, JOHN WATT, of Elmbank, Polmont, in the County of Stirling, North Britain,
Marine Engineer, do hereby declare the nature of this invention to be as follows:-
This invention, which relates to improved means of and apparatus for lubri-
cating, has for its object to lubricate certain parts of machinery such as the
bearings of engines and other parts from a source of automatic supply, such as is
obtained by gravity pressure as well as to economise the oil used, and which in
its simplest form consists of an upright tubular container. The container is
composed of glass or partly of glass and permits free inspection to be made of its
contents at any time. The lower end of this tubular container constitutes a
bracket to allow it to be fixed in any desired situation. Two inlet ports or
passages are provided at the lower end of the container aforesaid which have
communication with oil and water accumulators. The oil and water accumulators
are for the storage of these liquids, the latter being employed as a vehicle in
which the oil is floated and is so situated as to allow of a sufficient head or gravity
pressure to be made in order to send the oil to varying distances and heights
where lubrication may be required. Where the oil and water communicate or
are led, by the inlet ports to the container, two valve stems project transversely
through the casing. These stems or rods are mounted on their inner ends with
valves which regulate and control the flow of oil and water. The valve rods
work freely through stuffing boxes and glands.
When it is desired to lubricate the bearings or such other parts connected to
the container it is only necessary to unscrew the valves from their seats respec-
tively by the rods last mentioned.
The oil floating on the water is always uppermost in the container and by the
pressure exerted by the head or gravity already referred to, finds its way to the
parts to be lubricated. Between the container and the parts to be lubricated a
stop cock or stop-cocks may conveniently be placed by which means the several
parts may be lubricated simultaneously, or the parts may be lubricated at indi-
vidual periods of time as they may require.
The top and bottom of the container is so constructed as to afford ready means
of access when required for cleaning.

Improved Means of and Apparatus for Lubricating.
I, JOHN WATT, of Elmbank, Polmont, in the County of Stirling, North Britain,
Marine Engineer, do hereby declare the nature of this invention and in what
Price 871

page_text: manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
My invention, which relates to improved means of and apparatus for lubricating
has for its object to lubricate certain parts of machinery, such as the main
bearings, cross-head, crank pin, and guides, of engines and other parts from a
source of automatic supply, such as is obtained by gravity pressure as well as to
economise the oil used.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings, of which,
Figure 1 is a transverse section and plan of one form of what may be called
the apparatus for controlling the supply of the lubricant in my invention with
the oil and water valves open.
Figure 1 is a part section on the opposite plane to Figure 1 and drawn on an
enlarged scale, shewing the special construction of the valve chamber for the
admission of the oil.
Figure 2 is a front elevation of the said controlling apparatus, in duplicate,
although a greater number may be employed, as, for example, one for each part
to be lubricated, such as the main bearings, crosshead, crank-pin and guide
aforementioned, and
Figure 3 is a general view illustrating one of the forms of the whole apparatus
in my invention including the source of water and oil supply.
In a simple form of the said controlling apparatus there is an upright tubular
container A, which is composed of glass or partly of glass B, and permits free
inspection to be made of its contents at any time. The lower end of this tubular
container A constitutes a bracket C to allow it to be fixed in any desired situation.
Two inlet ports or passages D and D' are provided at the lower end of the
container A aforesaid which have communication by the pipe connections e and f
with oil and water accumulators E and F respectively, shewn in Figure 3, the
oil accumulator E is capable of being raised or lowered by the rod and screw E,
should that be wished, for example, according to whether light or heavy oils are
used. The oil and water accumulators E and F are for the storage of these liquids
and the water accumulator is situated so as to allow of a sufficient head of gravity
pressure to gravitate the oil to the various places where lubrication may be
required. The oil and water are led by the inlet ports D and D¹ to the container
through two valves H and H¹ whose stems G and G¹ project transversely through
the casing. These valves regulate and control the flow of oil and water and the
relative proportions thereof. The valve rods work freely through stuffing
boxes I and I¹ and glands J and J. The stuffing box I is continued to form a
chamber covering port 6 in order that the oil and water may not meet until the
oil reaches the top of the cone shaped tube c.
The water passes through the port a and rises into the container and the oil
passing through the port 6 and into the cone shaped tube c by the passage d and
out at the top of the cone shaped tube in the shape of beads or globules and
being of less specific gravity than water, tends to be uppermost in the container,
and by the pressure exerted by the head of gravity already referred to, the oil
finds its way along the pipe k to the parts to be lubricated together with whatever
proportion of water is desired.
By opening or closing more or less the valves H and H₁ the proportion of oil
and water admitted to the container may be regulated and by entirely closing
the valve H for any desired period, oil alone will be supplied and will pass
upwards through the water remaining in the container.
A cooling vessel or chamber K is introduced but it may be omitted. The
cooling chamber when used, is fitted to surround the outlet pipes K and cold
water is circulated by the inlet pipe K¹, and outlet pipe K, in said chamber
to cool the outlet pipes and keep the oil and water passing through them of a
uniformly low and suitable temperature notwithstanding the heat of the engine
or other room. A stop cock or stop cocks may be conveniently placed between

page_text: the lubricators, the oil and water reservoirs and the parts to be lubricated.
The several parts may be lubricated simultaneously or the parts may be lubricated
at individual periods of time as they may require.
The top and bottom of the container are so constructed as to afford ready
means of access when required for cleaning.
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:-
-
1. For lubricating machinery. A single or multiple lubricating apparatus
composed of one or more containers furnished with controlling valves and apparatus
for regulating the admission of oil and water from accumulators, placed at a
higher level than the containers and parts to be lubricated and communicating
therewith by piping, substantially as described and illustrated in the accom-
panying drawings.
2. The combination of a lubricating apparatus of the kind referred to in Claim 1
with a cooling or refrigerating chamber or chambers within which cold water is
circulated around the outlet pipes of the apparatus in order to maintain the
lubricant at a suitably low temperature, substantially as described and illustrated
in the accompanying drawings.
