Improvements in Packing rings and Fittings for Glands and
Stuffing-boxes of Piston-rods and for like purposes.
I WILLIAM BALL of 124 Stamford Road Stalybridge near Manchester, Lancashire,
Chief Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to the manner in which I construct and arrange packing
rings and collars for stuffing boxes of engines, pumps and general steam, pneumatic
and hydraulic machinery whereby the rods passing through the packing held between
and by such compound rings are more free to vibrate and a less amount of friction
is caused than with the existing systems of packing.
In engines and machines which are not perfect in their allignment considerable
friction is induced by the hammering of the rod in its packing, which my invention
is designed to obviate.
In applying my invention to an ordinary steam engine cylinder having a mitred
stuffing box and gland of the usual form I construct a pair of loose plates or discs
having a hole through the centre for the piston rod to pass freely through, the outer
diameter of the plates or discs being equal to the external diameter of the stuffing
box. These discs are only necessary to give a flat surface to the ends of the
gland and neck bush or in the packing space in place of the mitres which are
generally there.
Beneath the top plate or disc I place an upper ring formed with an internal top
flange the underside of which is tapered or mitred. The outer part of the ring I
make of a diameter to fit tightly the diameter of the stuffing box. Beneath this
upper ring I place a lower ring having an internal bottom flange which rests upon
the loose plate or disc covering the nitred end of the chamber. The external
diameter of the lower ring make equal to the internal diameter of the upper ring,
so that the upper ring may pass down and over the lower ring. The inner surface
of the lower ring I taper for the purpose of guiding the packing towards the rod
and that no ledge or shoulder shall be formed; while the bottom flange I also taper
or mitre, to similarly direct the packing towards the rod. The lower end of the
bottom ring I construct with an outer flange to enable it to form a stop or rest for
the upper ring to come upon when it is right down and when the packing requirés
to be renewed.
I construct my rings out of metal or any other suitable material and I build
them up in segments or pieces so as to enable me to apply them to any piston
or other rod without removing or disconnecting the rod in any way.
When applying my improved rings to any new engine pump or machine I
construct the stuffing box and gland with square ends so that loose discs or
plates are not required to be used with my rings when thus applied in the first
instance.
I do not limit the application of my invention to any peculiar form of packing or
to any particular kind of material of construction.

Improvements in Packing-rings and Fittings for Glands and
Stuffing-boxes of Piston-rods and for like purposes.
I, WILLIAM BALL of 124 Stamford Road, Stalybridge, near Manchester, in the
County of Lancashire, Chief Engineer, do hereby declare the nature of this inven-
tion 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 the manner in which I construct and arrange packing
rings and collars for stuffing boxes of engines, pumps, and general steam pneumatic
and hydraulic machinery, whereby the rods passing through the packing held between
and by such compound rings, are more free to vibrate, and a less amount of friction
is caused than with the existing systems of packing.
In engines and machines which are not perfect in their allignment considerable
friction is induced by the hammering of the rod in its packing, which my invention
is designed to obviate.
In applying my invention to an ordinary steam engine cylinder having a mitred
stuffing box and gland of the usual form I construct a pair of loose plates or discs
having a hole through the centre for the piston rod to pass freely through, the outer
diameter of the plates or discs being equal to the external diameter of the stuffing box.
These discs are only necessary to give a flat surface to the ends of the gland and
neck bush or in the packing space in place of the mitres which are generally there.
Beneath the top plate or disc I place an upper ring formed with an internal top
flange the underside of which is tapered or mitred. The outer part of the ring!
make of a diameter to fit tightly the diameter of the stuffing box. Beneath this
upper ring I place a lower ring having an internal bottom flange which rests upon
the loose plate or disc covering the mitred end of the chamber. The external
diameter of the lower ring I make equal to the internal diameter of the upper ring,
so that the upper ring may pass down and over the lower ring. The inner surface
of the lower ring I taper for the purpose of guiding the packing towards the rod
and that no ledge or shoulder shall be formed; while the bottom flange I also taper
or mitre to similarly direct the packing towards the rod. The lower end of the
bottom ring I construct with an outer flange to enable it to form a stop or rest for
the upper ring to come upon. when it is right down and when the packing requires to
be renewed.
I construct my ring out of metal or any other suitable material and I build them
up in segments or pieces so as to enable me to apply them to any piston or other rod
without removing or disconnecting the rod in any way.
When applying my improved rings to any new engine, pump or machine, I
construct the stuffing box and gland with square ends so that loose dises or plates
are not required to be used with my rings when thus applied in the first instance.
I do not limit the application of my invention to any peculiar form of packing or
to any particular kind of material of construction.
In the accompanying drawings, on Sheet 1 Fig. 1 is a sectional elevation of a
stuffing box and gland constructed according to my present invention, having out-
side independent stuffing box arranged upon the top of the cylinder cover and kept
in position by means of screws and nuts together with the outside cap or cover plate.
A being the piston rod, B the bush or lines within the cover, C the studs with their
nuts CD the cover or cap plate which the nuts rest upon and which rests upon the
upper portion of the top ring E; F is the lower ring resting upon the cylinder cover
bush, and of such a diameter internally that the upper ring E can slide freely
down and within it; the packing being held within the inner receptacles or
spaces e. f.
Fig. 2 Sheet 1 is a sectional elevation of my invention applied to an ordinary
existing type of stuffing box and gland, for the purpose of converting it into my
improved form of packing gland. A being the piston rod B₁ the neck bush in the

page_text: cover, H the interior of the stuffing box into which I place my improved rings K. L.
having inner space for holding the packing k. ; G is the ordinary gland with
bush G', having studs C and nuts C¹ for keeping the packing tight.
Fig. 3 Sheet 2 is a sectional elevation of my improved rings giving a long range
of compression and adjustment for the packing the rings; N1 N³ being free to enter
and be collapsed into the lower ring N, which lower ring I arrange to seat upon a
make-up ring M that I place upon the mitre of the ordinary gland bush B².
Fig. 4 Sheet 2 is an alternative arrangement I sometimes adopt when making my
rings in separate pieces. The outer ring O having an upper flange which rests in
the recessed surface of the inner ring P, suitable screws T. T T securing the one
portion readily to the other. The lower ring R I also build up with a projecting
flange U having screws S to secure it to the body R.
By this building up system of construction I can attach my improved rings to any
piston rod or slide rod without disturbing any of the connections; the rings being
composed of segments or semicircular portions to permit of easy application.
I do not limit my improved ring system of packing holders to any particular or
peculiar form of packing, but I employ any kind of ordinary or metallic packing to
work with my improved rings with similar advantageous results; I also employ my
packing rings for use upon pump plungers and press rams; and I modify the form
of attachment or the exact shape of the packing space to suit any particular or peculiar
requirement.
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:-
1. The construction of packing rings having one portion to slide within the other
such as E and F Fig. 1 as and for the purposes bereinbefore described and sub-
stantially as illustrated in the accompanying drawings.
2. The combination and arrangement of loose rings such as K and L illustrated
in Fig. 2 of the accompanying drawing, together with an ordinary stuffing box
and gland such as H and G, substantially as and for the purposes set forth.
3. The combination and arrangement of loose and independent packing rings
such as N. N' N together with a mitred seat such as M as and for the purposes set
forth and substantially as illustrated in Fig. 3 of the accompanying drawings.
4. The construction of loose packing rings having the outer and inner portions
built up by means of separate rings, flanges and segments, substantially as herein-
before described and as illustrated in Fig. 4 of the accompanying drawings.
