Improvements in Stuffing-boxes.
I JOHN SEATON WARBURTON of 49 New Road, Grays, in the County of Essex
Mechanical Engineer do hereby declare the nature of my said invention to be as
follows:-
The application to the stuffing boxes or glands hereinafter called the "stuffing box”
of piston rods or slide valve rods or other rods having a reciprocating or vibratory
motion hereinafter called the "rod" of steam air gas or other engines of one or more
hollow metallic or other rings or other means whereby one or more currents or streams
of oil grease water or other suitable fluid or semi-fluid hereinafter called the "oil" is
made to enter such "stuffing box" at one or more points and pass around such "rod"
and finally escape through one or more outlets bereinafter called the "outlet"
provided for that purpose at another part of the "stuffing box " in such manner as to
carry away any grit or dirt from the working surface of the "rod" and at the same
time ensure efficient lubrication. The "oil" may be heated or cooled to such
temperature as may be found desirable. I prefer to introduce the
"oil"
within the "stuffing box" at a head or pressure greater than the maximum
pressure of the steam or other motive fluid which is actuating the engine
or it may be introduced at an equal or lower pressure or at a constant
or variable pressure and either continuously or intermittently as circumstances
require. The head or pressure of the "oil" may be obtained by gravity or by
a force pump or injector or other suitable means and the "outlet" for its exit may be
provided with a relief valve weighted or loaded to the desired pressure or the with-
drawal of the "oil" from the "stuffing box" may be effected by a suction pump or
its equivalent. The "oil" after leaving the escape "outlet"
be filtered or
cleansed or heated or cooled and be again introduced or circulated through the
"stuffing box" so as to maintain a continuous or intermittent stream with the sinallest
possible quantity suitable means being provided to make up actual loss or waste. The
oil "
may be introduced to the interior of the "stuffing box" or be allowed to escape
therefrom by means of ports or, passages provided within the "rod" for that purpose.
Reducing valves or relief valves or suitable cocks or distributing valves may be
used in combination with pumps or other arrangements for controlling the supply of
the oil" to one or more "stuffing boxes' of one or more engines either simul-
taneously or otherwise. A suitable indicating apparatus or alarm inay be provided to
give notice by sound or other signal if the supply of "oil" falls short or is in excess
of the quantity desired and recording or measuring apparatus may be fitted to any
part of the mechanism by which the supply of the "oil" is controlled.

Improvements in Stuffing-boxes.
I, JOHN SEATON WARBURTON of 49, New Road Grays in the County of Essex
Mechanical Engineer do hereby declare the nature of my Invention for IMPROVEMENTS
IN STUFFING BOXES 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 application to the stuffing boxes or glands hereinafter
called the "stuffing box" of piston rods or slide valve rods or other rods having a

page_text: ""
reciprocating or vibratory motion hereinafter called the "rod" of steam air or gas
engines of one or more hollow metallic rings whereby one or more currents or
streams of oil grease or other suitable fluid or semi-fluid hereinafter called the "oil"
is made to enter such "stuffing box" at one or more points and pass around such
« rod
and finally escape through one or more outlets hereinafter called the
"outlet" provided for that purpose at another part of the "stuffing box" in such
manner as to carry away any grit or dirt from the working surface of the "rod
and at the same time ensure efficient lubrication. The "oil" may be heated or
cooled to such temperature as may be found desirable. I prefer to introduce the
"oil" within the "stuffing box at head or pressure greater than the maximum
pressure of the steam or other motive fluid which is actuating the engine and it
may be introduced at a constant or variable pressure and either continuously or
intermittently as circumstances require. The head or pressure of the "oil" may
be obtained by gravity or by a force pump injector or other suitable means and
the outlet for its exit may be provided with a relief valve weighted or loaded to
the desired pressure or the withdrawal of the "oil" from the "stuffing box"
be effected by a suction pump or its equivalent. The "oil" after leaving the
escape outlet may be filtered or cleansed or heated or cooled and be again
circulated through the "stuffing box so as to maintain a continuous or inter-
mittent stream with the smallest possible quantity suitable means being provided
to make up actual loss or waste. The "oil" may be introduced to the interior
of the " stuffing box"
or be allowed to escape therefrom by means of ports or
passages provided within the "rod" for that purpose. Reducing valves or relief
valves or suitable cocks or distributing valves may be used in combination with
pumps or other arrangements for controlling the supply of the "oil" to one
or more "stuffing boxes" of one or more engines simultaneously or otherwise.
Referring to the accompanying drawings :-
may
Fig. 1 is a vertical section of the cylinder X of a steam air or gas engine having the
usual "stuffing box" Z for the piston "rod" which "stuffing box" Z contains the
usual packing and about midway between the coils of such packing I place a circular
ring W of metal or other suitable material. The ring W is provided with one or
more annular chambers or recesses d formed upon its inner surface in such manner as
to encircie or surround the working surface of the piston "rod" and suitable ports or
openings cand e are provided at opposite sides of the ring W to permit the access and
escape of the "oil" or other lubricant to and from the interior annular chambers or
recesses d.
A port or passage is provided at one side of the "stuffing box" to permit the access
of the "oil at the inlet a which inlet is provided with a cock or regulating valve b
while the opposite side of the "stuffing box" is in like manner provided with a port
or passage serving as an outlet to g which outlet is provided with a relief valve f which
relief valve may be loaded by a spring or weight. A stream of "oil" being supplied
under a suitable head or pressure from a force pump or otherwise to the inlet a passes
through the regulating cock or valve whence it enters the annular chamber d of
the ring W by means of the port c and passing around the piston "rod" Y escapes
from the annular chamber d by means of the port e on the opposite side of the ring W
and thence through the loaded valve f to the outlet g carrying away with it any dirt
or grit which may be upon the surface of the piston "rod" Y. Fig. 2 shows a cross
section and plan of the ring W upon an enlarged scale. Fig. 3 shows the manner of
arranging the ring W in halves to facilitate its application to and withdrawal from a
'stuffing box" without disturbing the piston "rod" Y shown in Fig. 1.
"
Figs. 4-5-6 show various forms of rings W in cross section in order to illustrate
the manner in which by the formation of two or more annular chambers or recesses d
and d¹ the oil may be made to pass around the piston "rod" in one or more streams
or encircle the "rod more than once as determined by the number and arrangement
of the inlet ports o and o' and the outlet ports e and e¹.
"

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
I. The application to the "stuffing boxes" of the piston rods or slide valve rods or
other rods having a reciprocating or vibratory motion of steam air or gas engines of
one or more circular rings W having one or more internal annular chambers or
recesses d and provided with suitable inlet ports c and outlet ports e for the purpose
of admitting "oil" or other fluid or semi-fluid lubricant to the working surface of the
piston "rod"
or other rods" at a point between the coils of the packing
within such "stuffing boxes" substantially as and for the purposes shown and
described.
II. The arrangement and combination of suitable cocks or regulating valves b and
relief valves f either together or separately with the circular ring W for
controlling the supply and regulating the pressure of the "oil"
fluid or semi-fluid lubricant substantially as and for the purposes shown and
described.
or other
III. The arrangement and combination within the "stuffing boxes" of steam air
or gas engines of one or more rings W made of metal or other suitable material in one
or more parts or sections and having one or more annular chambers d or their
equivalent formed within the inner surface of the rings and provided with one or more
inlet ports c and one or more outlet ports e substantially as and for the purposes shown
and described.
