AN IMPROVED PACKING FOR STUFFING BOXES OF STEAM ENGINES
Year: 1884

page_text: I GEORGE RODGER, of Michaelson Villa, Barrow in Furness in the County of
Lancaster, Engineer do hereby declare the nature of my said Invention for
AN IMPROVED PACKING FOR STUFFING BOXES OF STEAM ENGINES to be as
follows:-
My Invention relates to an improved packing for stuffing boxes of steam engines
and consists of the following arrangement of packing and stuffing box. I form and
use a series of white metal divided rings of size to suit the rod being packed
and of diameter less than that of the stuffing box into which they are placed and
I make the stuffing box main gland of size to come over the outside of these rings
and into the stuffing box, so that a stuffing box is formed outside of the rings and
also a secondary stuffing box is formed between the rod being packed and the inside
of the main gland. This secondary stuffing box is provided with a secondary gland
of inside diameter to correspond with the rod being packed. The stuffing box
outside of the white metal rings is filled with any common fibrous, or elastic
packing, but by preference asbestos which packing on the gland being screwed
up presses against the metal rings and through their being divided closes them
against the rod as they wear. The secondary stuffing box may be filled with any
suitable packing such as any common fibrous, or clastic packing and has for its
object to keep the white metal rings in their place one against another. The main
stuffing box gland is held in position by screwed studs from the cylinder, or other
vessel and the secondary gland is held in position by the same, or by screwed studs
in the main gland.
By my arrangement of packing, as above described I am enabled to use a ring
metal packing, which is pressed against the rod circumferentially by the tightening
of the main gland and kept in position longitudinally by the tightening of the
secondary gland, a steam tight joint being thus ensured,

I GEORGE RODGER of Michaelson Villa, Barrow in Furness in the County of

AN IMPROVED PACKING FOR STUFFING BOXES OF STEAM ENGINES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My Invention relates to an improved packing for stuffing boxes of steam engines.
The following is a description of my Invention in such full, clear and exact
terms, as to enable any one skilled in the art to which it belongs to put into
practice and use the same, reference being had to the accompanying sheet of
Drawings making a part of this Specification and to the letters and figures of
reference marked thereon like letters and figures being used to denote the same,
or corresponding parts throughout the various views and figures.

An improved packing for the stuffing boxes of steam engines, according to my
Invention consists of the following construction and arrangement of packing and
stulling box. I form and use a series of divided rings a of any suitable metal,
but by preference of white metal" and of size to suit the rod being packed and
of diameter less than that of the stuffing box A into which they are placed
and I make the stuffing box gland B to come over the outside of the rings a
and into the stuffing box A so that the stuffing box A is formed outside of the
rings a and there is also formed a secondary stuffing box C between the rod D
being packed and the inside of the gland B. This secondary stuffing box C is
provided with a secondary gland E of inside diameter to correspond with the
diameter of the rod D. The secondary gland E may be attached to the main
gland B as shown at Figure 1, or the secondary gland may be secured independently
of the gland B as shown at Figure 3, or in lieu of using the secondary gland E, the
secondary stuffing box C may be formed as shown at Figure 5, namely by boreing,
or turning down the inside of the gland B so as to leave a space between the gland B
and the rod D.
The "white metal" rings a are made in segments as shown at Figures 2. 4 and 6,
and the ends of the segments are bevelled down at a¹ so as to allow of their being
closed up as they wear away. The stuffing box A outside of the "white metal
rings a is filled with any common fibrous, or elastic packing b but by preference
asbestos packing, which on the gland B being screwed up presses against the
"white metal" rings a and by reason of their being divided closes them against
the rod D as they wear. The secondary stuffing box C may be filled with any
suitable packing d such as any common fibrous or elastic packing and has for its
object to keep the "white metal" rings in their place one against another.
The main stuffing box gland B is held in position by screwed studs from the
cylinder, or other vessel and the secondary gland E is held in position by the samo

the cylinder, or other vessel.
By my arrangement of packing as above described I am enabled to use a
ring metal packing, which is pressed against the rod D circumferentially by
the tightening of the main gland B and kept in position longitudinally by the
tightening of the secondary gland E, a steam tight joint being thus ensured.
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:
First The improved packing for stuffing boxes, as herein described consisting
essentially of the gland. (B) asbestos, or fibrous packing (b) metal packing rings (a)
and a secondary gland (E) and packing (d) as set forth in reference to Figures 1. 2.
3 and 4 of the Drawings hereto annexed.
Second The improved packing for stuffing boxes, as herein described consisting
essentially of the gland (B) asbestos, or fibrous packing (b) metal packing rings (a)
and a secondary stufling box (C) and a packing (d) as set forth in reference to
Figures 5 and 6 of the Drawings hereto annexed.
