Floating Metallic Automatic Packing.
I, EVAN TADMAN FERRIER, of 19, St. Andrews Crescent, Cardiff, in the County
of Glamorgan, Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
The present invention relates to improvement in metallic packing such as are
used on the rods of piston, valve, pumps and other rods.
Referring to the accompanying figures, which are to be taken as part of the
specification and read there with:-Figure 1 is a sectional view taken after a
portion of the packing has been broken away to show the internal portion of it.
Figure 2 is a plan of gland C, showing the packing ring along the line 2, 2, of
Figure 1.
Figure 3 is a plan of gland E, with two claws.
Figure 1, a portion of the packing has been broken away to show the internal
construction of it.
A is a piston rod, B, its stuffing box, C, the gland converted into a packing box
to receive the packings, and for convenience will name it gland or packing box C;
and D, the neck bush. F is a small gland with two lugs, one on each side, it
has a screw cut on the outside with a corresponding screw cut on the inside of
the inner end of gland C, into which it is screwed. E is a metallic ring, which
stands on the inner end of gland F, between that and the neck bush, it has a
shoulder on, to fit under the lugs of gland F, the function of which is to keep
ring E upon the adjacent flat face of gland F, that it may slide there on and at
right angles there with.
G, G, are two flat metallic rings made to pass smoothly over the rod, with ring H
between which has but one joint as shown in Fig. 2.
The rings G, G, bear upon an annular diaphragm, or ring J, which projecting
inwardly from the gland C, divides the cavity of it into two equal portions, these
rings G, G, with packing ring H, between, slide smoothly upon the adjacent flat
faces of diaphragm, and gland F of Fig. 1, and at right angles there with, and
is under constant pressure up against the rod A.
This pressure is exerted by an arcual spring I, the ends of which are bent at
right angles with its curve, and being made slightly shorter than the distance
between the slots a, a, of Fig. 2, and the ends being placed into the slots, contract,
and draws the packing ring up to the rod.
A spring I is of flat, or other suitable section, but is arcual.
I do not confine myself to the one packing ring H.
K, K, are two flat metallic rings made to pass over the rod, which are coned
on the inside next to the rod, and the ends of the packing ring L are also coned
to fit the cones in rings K, K.
Ring L has but one joint, the same as ring H or, may be made in segments,
which when pressed on the ends by the coned rings K, K, the segmental pack-
ing ring L is kept up to the rod in the same manner as by the one joint. Spring N

page_text: of Fig. 2 is passed over the rod, and over the gland studs, which is pressed when
adjusted, against gland M, through which the rod is allowed to pass freely. The
pressure is adjusted by the gland nuts being tightened against spring N, which
press against gland M, allowing the packing to slide smoothly over the adjacent
flat faces of diaphragm, and gland M, and at right angles there-with.
It is not my intention that the packing should be arranged in the exact manner
as shown in the accompanying drawings, for instance, the packing ring G, G,
and H, may be adopted in both cavities of gland C, or, in the place of ring E,
of Fig. 1.
The packing being now completed and placed in the gland, or packing box C,
the flange of which is brought into contact with the stuffing box flange, with lead
wire between, is tightened up and made a steam tight joint.
Having 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:
· 1. In a metallic packing of the class specified, the combination of gland, or
packing box and glands fitted, or screwed one into the other, into their respective
places, at each end of gland, or packing box, with annular diaphragm, or ring,
dividing the cavity of it into two equal portions, to receive the packings upon
the diaphragm, and at right angles there with, and over the adjacent flat faces
of which, the respective packings can slide as set forth.
2. In a metallic packing of the class specified, the combination of metallic ring,
or rings, placed on the inner small gland, which is screwed into the gland or
packing box, and at right angles therewith, over the adjacent flat face of which
the ring, or rings can slide as set forth.
3. In a metallic packing of the class specified, the combination of rings and
packing ring or rings between, with an arcual spring out side each such packing
ring, or rings, adapted to draw the packing ring up to the rod, the rings outside
the packing ring, or rings, and at right angles therewith, over the adjacent flat
faces of diaphragm and gland, the said rings can slide as set forth.
4. In a metallic packing of the class specified, the combination of rings coned
and coned ends of packing rings fitted into one another, adapted to press the pack-
ing ring up to the rod. The coned rings with packing ring between and at right
angles there-with, over the flat faces of diaphragm and gland the said rings can
slide as set forth.
5. In a metallic packing of the class specified the combination of an arcual
spring with ends bent at right angles with its curve, which is adapted to keep
the packing ring up to the rod, as set forth.
6. In a metallic packing of the class specified the combination of a flat spring
to pass over the rod and across the gland studs, which is adapted to press the the
coned rings against the segmental packing ring, to keep it up to the rod to be
packed, as set forth.
