PROVISIONAL SPECIFICATION,
Improved Means or Method of Effecting the Lubrication of Journals
and other Parts of Motive Power Engines.
We, JOHN RICILARDSON and WILLIAM DYSON WANSBROUGII, both of the Firm of
Robey and Company, Limited, Globe Works, Lincoln, Engineers, do hereby,
declare the nature of this invention to be as follows:-
This invention relates to a new method for lubricating quick running engines
from a fixed point, and consists of an oil reservoir which may be attached to a
pump, accumulator, or raised vessel, so as to make the necessary pressure, and
which is fixed, in preference, to the back part of the main standard carrying the
cylinders of vertical engines, or it may be fixed upon the trunk of a horizontal
engine in the same relative position to the working parts.
For properly carrying out this invention, a sliding slipper attached to the cross-
head is made of a length a little more than the length of the stroke, and has at
perforation in it at each end, the distance of the perforations apart being exactly
equal to the length of the stroke. From the perforated slipper, channels or
passages are carried to the crosshead pin, and from the connecting rods, or from a
tube attached to the connecting rod down to the crank pin, and any other working
parts to which it is desired to convey oil. The standard is perforated
at a point which is just midway of the stroke so that at each end of the
stroke the opening in the slipper is coincident with the opening
in the standard. All the working parts are for an instant at rest in this position,
and the oil being supplied under pressure they all twice in each revolution receive
a supply of oil.
During the intermediate positions no oil is received by the slipper but the oil
in the standard is forced under pressure at the back of the slipper. This produces
a film of oil against which the slipper itself works efficiently lubricating it.
Either liquid-oil, vaseline, or other suitable materials may be used.
The main feature of the invention is the method of introducing the oil at two
intervals in each stroke through a slipper and from a fixed point of the standard
from which point there is always oil under pressure carried by suitable tubes to
any of the stationary bearings of the engine which require lubrication.

page_text: 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
statement:
This invention relates to a new method for lubricating quick running engines
from a fixed point and consists of an oil reservoir and receiver which may be 5
attached to a pump, accumulator, or raised vessel, so as to make the necessary
pressure and which is fixed in preference at the back part of or near to the main
standard carrying the cylinders of vertical engines, or it may be fixed upon the
trunk of a horizontal engine. in the same relative position to the working parts.
For properly carrying out this invention, a sliding slipper attached to the cross- 1
head is made of a length a little more than the length of the stroke and has a per-
foration in it at each end, the distance of the perforations apart being exactly
equal to the length of the stroke.
From the perforated slipper, channels or passages are carried to the crosshead
pin, and from the connecting rods, or from a tube attached to the connecting rod 1
down to the crank pin, and any other working parts to which it is desired to convey
oil. The standard is perforated at a point which is just midway of the stroke, so
that at each end of the stroke the opening in the slipper is coincident with the
opening in the standard.
All the working parts are for an instant at rest in this position, and the oil being 2
supplied under pressure they all twice in each revolution receive a supply of oil.
During the intermediate positions no oil is received by the slipper but the oil
in the standard is forced under pressure at the back of the slipper. This produces
a film of oil against which the slipper itself works efficiently lubricating it.
Either liquid-oil, vaseline, or other suitable materials may be used.
The main feature of the invention is the method of introducing the oil at two
intervals in each stroke through a slipper and from a fixed point of the standard.
from which point there is always oil under pressure carried by suitable tubes to
any of the stationary bearings of the engine which require lubrication.
To enable our invention to be more fully understood, we show on the annexed
drawings a vertical steam engine in back -elevation Figure 1, and side elevation
Figure 2, with our preferred system of lubrication applied.
All the oil used in lubricating the engine.is.collected in the reservoir or well A.
In this well is arranged a strainer and a force pump the latter actuated from one
of the eccentrics or any moving part of the engine. This pump forces the oil into
the receiver B where it is maintained under a constant pressure. From the
receiver B two main distributions are taken to the right and left, C and D, to the
surface of the piston rod guide. This piston rod guide or slipper has a groove
within it equal in length to a little over its own stroke, and the slide itself is
made of greater length than its stroke so that the pipes leading from the reser-
voir A are always covered, and the pipe E which is attached to the crosshead is in
constant communication with the oil under pressure contained in this reservoir.
This pipe communicates in the first instance with the interior of the crosshead
pin, and from thence the pipe F descends to the crank pin through the large
end of the connecting rod.
Two other pipes extend to the right and left, G and H, to the valve rod guides
and pin and from thence by the pipes I and J to. the eccentrics.
The main bearings are lubricated by fixed pipes K, L, and M, and all the oil is
returned to the reservoir through pipes or drains arranged for the purpose.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is:-
1. The method of introducing the oil at two intervals in each stroke through a
slipper and from a fixed point of the standard and from which point there is
always oil under pressure carried by suitable tubes to any of the stationary bearings
of an engine requiring lubrication as described.

page_text: 2. The reservoir B containing oil under pressure and the method of distributing
the same to both ends of the connecting rods through the fixed pipes C and D) in
the slide substantially as above described.
3. The particular arrangement of pump, pipes, grooved slipper and delivery ends
to the various parts of the structure requiring lubrication as represented in the
annexed drawings.
