Improvements in and Apparatus for Lubricating Piston Rods, Valve
Spindles, and other Revolving or Reciprocating Shafts
Spindles.
or
We RALPH PEACOCK, of Goole, in the county of York, Engineer and JACOB BIRD,
of Hull in the county of York, Engineer do hereby declare the nature of this invention
to be as follows :-
This invention relates to automatically lubricating piston rods, valve spindles, and
other revolving or reciprocating shafts or spindles working through stuffing boxes
or glands in steam or other engines, centrifugal pumps and other machinery.
In carrying out our invention the stuffing box or rod to be lubricated is provided
with a brass ring placed at the bottom of the packing spaces of the stuffing box; the
said ring forms a doublo cone and is perforated with holes from the outside to the
inside cone for the flow of the oil or other lubricant which is supplied from a tallow
cup or lubricator connected by a suitable pipe to the bottom of the stuffing box by
gravitation or by steam taken from the main steam pipe or valve chest casing to the
tallow or oil cup; or injected into the pipe conveying the oil to the ring at the bottom
of the stuffing box.
By this means the lubrication will be automatically effected as the lubricant will be
thoroughly and effectually diffused over and be brought in contact with the working
part of the piston rod valve or other spindle or stuffing box to be lubricated.
In marine engines our improved method of lubricating will entirely dispense with
the necessity of hand swabbing the piston rods and valve spindle, and will effect an
economy of oil and packing, at the same time effecting a reduction of friction and of
wear and tear of both the piston rods and packing.
It will be obvious that our improvements are applicable to the ordinary new neck
rings of stuffing boxes.

Improvements in and Apparatus for Lubricating Piston Rods, Valve
Spindles, and other Revolving or Reciprocating Shafts
Spindles.
or
We, ARTHUR JAMES PEACOCK and JANE PEACOCK, both of Goole, in the County
of York, Executors under the Will of Ralph Peacock late of Goole aforesaid Engineer
deceased, and JACOB BIRD of Hull, in the County of York 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 to automatically lubricating piston rods, valve spindles and
other revolving or reciprocating shafts or spindles working through stuffing boxes or
glands in steam or other engines, centrifugal pumps and other machinery, and the
invention consists mainly in introducing the lubricant into a space or receiver in the
stuffing box at the extreme end or near the inner end of the packing space without
materially diminishing the packing or packing space in the stuffing box.
In carrying out this invention the rod to be lubricated is provided with a brass ring
placed at the inner end of the packing spaces of the stuffing box; the said ring forms
à double cone, that is to say, it is provided with a conical or other shaped groove on
the outer side and with a similar groove on the inner side, and the ring is perforated
with holes for the flow of lubricant which is supplied from a lubricator connected by a
suitable pipe to the inner end of the stuffing box by gravitation or by steam taken
from the main steam pipe or valve chest casing to the lubricator, or injected into the
pipe conveying the oil to the receiver at the inner end of the stuffing box.
In order to enable this invention to be fully understood, we will describe how the
same can be carried into practical effect by reference to the accompanying drawing,
in which figure 1 represents an elevation of a steam engine cylinder and its slide
valve casing, the stuffing boxes of the same being represented in section shewing the
lubricating apparatus applied to the piston rod and valve spindle; figures 2 and 3
represent a plan and a vertical section respectively of the ring for lubricating piston
rods, valve spindles, and other revolving shafts or spindles. Similar letters indicate
similar parts in all the figures.
Referring to figures 2 and 3, a, is the lubricating apparatus or ring preferably
formed of brass and in halves so as to more readily adapt it to be placed at the inner
end of the packing spaces of the stuffing boxes of steam engines or the like and around
the spindles or rods working through the said stuffing boxes. b, and c, are the grooves
on the outer and inner sides respectively of the ring a, and d, d, are the holes through
which the oil flows from the groove b, to the groove c. In figure 1 two of the.
rings a, a, are shewn applied to the stuffing boxes A and B of a steam engine
cylinder C, and its slide valve casing D for lubricating the piston rod E, and valve
spindle F. The said rings are connected to and supplied with oil or other lubricant

page_text: from a tallow cup f, or its equivalent, by means of a pipe e, the oil flowing to the
rings a, a, by gravity or it may be forced in by steam pressure or other means as
hereinbefore described.
By this means the lubrication will be automatically effected, as the lubricant will
be thoroughly and effectually diffused over and be brought in contact with the
working part of the piston rod E, and valve spindle F.
In marine engines our improved method of lubricating will entirely dispense with
the necessity of hand swabbing the piston rods and valve spindle, and will effect an
economy of oil and packing at the same time effecting a reduction of friction and of
wear and tear of both the piston rods and packing.
Instead of using the rings a, a, it will be obvious that the ordinary neck rings or
bushes of stuffing boxes can be formed with the grooves b, and C, for the purpose
hereinbefore described.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. The herein described method of lubricating piston rods, valve spindles and other
revolving or reciprocating shafts or spindles working through stuffing boxes or glands
by the automatic introduction of the lubricant into a space at the inner end of the
stuffing box or gland in such a manner that the lubricant will be forced into or
through the packing and will be effectually diffused over the working part of the
piston or other rod, shaft, or spindle, substantially as herein before described.
2. The use of the herein described rings substantially as and for the purpose set
forth.
3. The improved apparatus for lubricating piston rods, valve spindles and the like
hereinbefore described and illustrated in the accompanying drawing.
