I JOHN PATON of 29 Newry Street, Holyhead, Chief Engineer do hereby declare
the nature of my invention for "IMPROVEMENTS IN THE METHOD OF LUBRICATING
CERTAIN PARTS OF MACHINERY AND IN APPARATUS THEREFOR to be as follows:-
"
This invention relates more particularly to the lubrication of the moving parts of
oscillating engines such as the pistons and piston rods valve spindles and the like
which are usually lubricated by hand at considerable intervals of time greatly to
the detriment of the machinery which is apt to beat and has to be cooled by the
application of water.
I accomplish the lubrication continuously by apparatus constructed essentially as
follows, though considerable modifications may be made in details.
A tank to contain water is preferably placed at a higher level than the part of
the machinery to be lubricated and a portion of this may be divided off to contain
the lubricant; or the lubricant may be contained in a separato vessel. Taps or
valves regulate the two streams which may be united in a third vessel where the
resulting fluid collects and whence it passes by a small pipe which may be flexible
if desired and is preferably fixed near the top of the vessel to the part to be
lubricated.
Instead of the tanks above mentioned water and oil under pressure may be led
to the third vessel and conveyed to the required point as before.

I JOHN PATON of 29 Newry Street Holyhead, Chief Engineer 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: —
This invention relates more particularly to the lubrication of the moving parts
of oscillating engines such as the piston rods valve spindles and the like which are
usually lubricated by hand at considerable intervals of time greatly to the detriment
of the machinery which is apt to heat and has to be cooled by the application of
water.
I accomplish the lubrication continuously by apparatus constructed essentially as
follows, though considerable inodifications may be made in details.
A tank to contain water is preferably placed at a higher level than the part of
the machinery to be lubricated and a portion of this may be divided off to contain
the lubricant; or the lubricant may be contained in a separate vessel. Taps or
valves regulate the two streams which may be united in a third vessel where the
resulting fluid collects and whence it passes by a small pipe which may be flexible
if desired and is preferably fixed near the top of the vessel to the part to be
lubricated.
Instead of the tanks above mentioned water and oil under pressure may be led
to the third vessel and conveyed to the required point as before.
The accompanying drawing represents a view partly in section of an oscillating
cylinder A to which is secured the pipe B of small bore communicating with the
tank C which contains water or oil and water mixed or in separate compartments,
the valve D serving to cut off the supply when desired.
:
The open end of B is turned so as to deliver into the recess E of the stuffing
box F and thence the water or water and oil pass by the grooves G (of which
there are any convenient number say three) and holes H in the gland I on to the
piston rod K, being thus delivered close above the packing and well down in the
gland.
The tank C is located above the level of the stuffing box to be supplied in order
that a convenient flow by gravitation may be obtained. The object of the long
bend B of the pipe B is to bring the end as near to the centre-of motion of the
cylinder and is adopted in this case in consequence of the cylinder being an
oscillating one. The pipe B may be flexible if desired.
The drawing serves to shew one application only of this invention in order that
the invention itself may be understood, but the application of the invention is not
limited to that particular application.
I am aware that the mere idea of applying water for the purpose of cooling
bearings is not novel, water being commonly applied for this purpose to the thrust
bearings of the propeller shafts of screw steamers and to other bearings where the
friction is exceptionally severe; therefore I make no claim for the simple appli.
cation of water for that purpose.

page_text: In my invention however the water is applied as a lubricant not to the ordinary
bearings which if properly constructed and of sufficient area will generally keep cool
of themselves but to rods such as piston rods and valve spindles which are heated to
a high degree by the steam and travel at a high speed to and fro in their bearings
which have of necessity in most cases to be so constructed that they fit as closely
as possible around the rod in order to prevent the leakage of steam, thus causing
considerable friction which is increased by the hemp or other packing which they
contain and which is tightly compressed against the rod.
The tank may be supplied with water in any convenient manner and if desired
may be itself a surface condenser and may be fixed to the cylinder and oscillate
with it.
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
The application of water as a lubricant for the stuffing boxes of piston rods and
the like..
