I ASPLAN BELDAM, of 77 Gracechurch Street, in the City of London, in the
County of Middlesex, Consulting Engineer and Ship Surveyor do hereby declare
the nature of the said Invention for AN IMPROVED PACKING FOR THE STUFFING
BOXES OF STEAM ENGINES AND PUMPS AND FOR SIMILAR JOINTS' REQUIRING TO BE
MADE STEAM, AIR, OR WATERTIGHT to be as follows:-
My Invention relates to a certain improved packing to be used for the stuffing
boxes of steam engines and pumps and for similar joints requiring to be made steam,
air, or watertight.
A packing according to my Invention consists of rings of white metal, gun metal,
or other suitable metal, the face of which is kept up to the surface being packed by
springs, such rings and springs being either contained in a false stuffing box made
to fit the stuffing box proper, or the rings and springs may be made to fit the
stuffing box proper without using a false stuffing box. The metallic rings can be
made in various forms and may be formed in halves or in several pieces and fitted
to the rod, or surface to be packed. These metal rings, or sections are held, or
pressed to the surface to be packed by a spring, or springs. The springs can be
made spiral stretching circumferentially round the rings, or fitted in short lengths
onto the rings, or onto bolts attached to snugs, or bushes. The sougs may be
made of steel, or other metal, of flat, round, or other section, corrugated, or plain.
When the rings and springs are contained in a false stuffing box, the said stuffing
box is inserted into the stuffing box proper with the rings pressed up to the surface
to be packed, by the springs. The rest of the stuffing box proper is filled up with
fibrous packing, or with alternate layers of rings or springs and fibrous packing, or
with a number of rings and springs. When the false stuffing box is not used, the
rings are made to fit the stuffing box proper, the springs being held in position
by plates and studs. The pieces which form the rings are kept together by
springs retained by bolts, or the pieces may be held together and pressed up to
the surface to be packed by circumferential springs of spiral, or other form.

the nature of the said Invention for AN IMPROVED PACKING FOR THE STUFFING
BOXES OF STEAM ENGINES AND PUMPS AND FOR SIMILAR JOINTS REQUIRING TO
BE MADE STEAM, AIR, OR WATERTIGHT, 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 a certain improved packing to be used for the stuffing
boxes of steam engines and pumps and for similar joints requiring to be made steam,
air or watertight.
A packing according to my Invention consists of rings of white metal, gun metal,
or other suitable metal, the face of which is kept up to the surface being packed by
springs, such rings and springs being either contained in a false stuffing box made
to fit the stuffing box proper, or the rings and springs may be made to fit the
stuffing box proper without using a false stuffing box. The metallic rings can be
made in various forms and may be formed in halves, or in several pieces, and fitted
to the rod, or surface to be packed. These metal rings, or sections are held, or
pressed to the surface to be packed by a spring, or springs. The springs can be
made spiral stretching circumferentially round the rings, or fitted in short lengths
onto the rings, or onto bolts attached to, spugs, or bushes. The snugs may be
made of steel, or other metal, of flat, round, or other section, corrugated, or plain.
When the rings and springs are contained in a false, stuffing box, the said stuffing
box is inserted into the stuffing box proper with the rings pressed up to the surface
to be packed by the springs. The rest of the stuffing box proper is filled up with
fibrous packing, or with alternate layers of rings and fibrous packing or with a
number of rings and springs. When the false stuffing box is not used the rings
are made to fit the stuffing, box proper, the springs being held in position by
plates and studs. The pieces which form the rings are kept together by springs
retained by bolts, or the pieces may be held together and pressed up to the surface
to be packed by circumferential springs, of spiral, or other form.

Figure 6 is a sectional plan through X X Figure 5.
Figure 7 is a sectional elevation of a piston rod gland and stuffing box, provided
with packing rings according to my Invention, such packing rings being suitable
for use without a false stuffing box as shown, or with a false stuffing box.
Figure 8 is a sectional plan through X X Figure 7.
In reference to Figures 1 and 2. A is the stuffing box proper. B is the gland.
C is the neck bush. D is the piston rod. A packing according to my Invention
consists of the rings a which are of white metal, gun metal, or other suitable metal,
the face of which is kept up to the surface of the piston rod D by the springs e,
which press on the outer ring a¹ and thereby keep the rings a up to the surface of
the rod D. The rings a a are contained in a false stuffing box 6 made to fit the
stuffing box proper A. The stuffing box b is preferably made in two pieces, and is
provided with cups b₁ to receive the spiral springs e, lugs & being provided on the
ring a which fit into the springs e. The metallic rings a a and the false stuffing
box b are inserted into the stuffing box proper A and the remainder of the stuffing
box is packed with fibrous, or other suitable packing E.
In the modification shown at Figures 3 and 4 one metallic ring a is used and
segmental rings b are substituted for the false stuffing box. The springs e are held
in the cups which are in this case formed on the ring a, the lugs & being formed
on the rings b. The ring a is made in two pieces which two pieces are held, or
pressed together by the springs el carried by the snugs a' and the bolts a³. This
form of metallic ring a is inserted into the stuffing box proper A which is then
filled up with fibrous, or other suitable packing E.
In the modification shown at Figures 5 and 6, the rings a are contained within
the false stuffing box b and kept up to their work by the springs e, additional
springs f being provided to keep the rings a in position in the false stuffing box b.
Over the false stuffing box 6 there is a ring g provided with springs h which bear
between the ring g and the false stuffing box b. Below the false stuffing box b
a layer of fibrous, or other suitable packing E is used.
In the example shown at Figures 7 and 8 the rings a are formed with a
circumferential groove b¹ and two circumferential springs e e are provided, fitting
into recesses 6 on the ring a. The springs e e are connected together by two
lengths of chain, or wire, or cord k, which fit in the circumferential groove b'.
The rings a with the springs e and chains k can be used to pack a stuffing box in
the manner shown at Figure 7 in conjunction with the fibrous, or other suitable
packing E, or they can be used in conjunction with the false stuffing box b.
I would also have it understood that the rings and false stuffing boxes shown at
Figures 1. 3 and 5 can be used in conjunction with other packing as shown, or the
stuffing boxes A can be filled entirely with the metallic spring rings, and false
stuffing boxes.
I would have it known that I am aware that Letters Patent dated January 14th
1884 and No 1428, have been granted to James Henry Smith and Robert Marshall
for An improved packing for the stuffing boxes of piston rods and other rods -
requiring packing and I would have it understood that I do not make
any claim
to anything covered and claimed by the said James Henry Smith and Robert
Marshall in the Specification of this Patent No 1428 A.D. 1884.
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 In a stuffing box in which metallic packing is employed, the combination
of the false box, or holder (b) springs (e) and metal rings (a a') as set forth with
reference to Figures 1 and 2 of the Drawings hereto annexed.

page_text: Second In a stuffing box in which metallic packing is employed, the combination
of the holder (b) springs (e) and metal segments, or rings (a) and springs (el) as
set forth with reference to Figures 3 and of the Drawings hereto annexed.
Third In a stuffing box in which metallic packing is employed, the combination
of a false box, or holder (b) springs (e) and rings (a) and springs (f) and ring (g)
and springs (h) as set forth with reference to Figures 5 and 6 of the Drawings
hereto annexed.
Fourth In a stuffing box in which metallic packing is employed, the combination
of the springs (e) and chains (k) and the rings (a) as set forth with reference to
Figures 7 and of the Drawings hereto annexed.
