I, REUBEN THOMAS PRESTON, of the Firm of J. Stone and Company, of Deptford,
in the County of Kent, Engineers, do hereby declare the nature of this invention
to be as follows:-

My invention relates to improvements in packing or bearings for reciprocating
revolving rods, shafts and the like.
According to my invention I mount in the stuffing box or in the bracket or
the like one or more rings of comparatively hard metal or material having one or
more inclined faces and one or more rings of comparatively soft metal or material
having one or more inclined faces, the inclined face of one ring coinciding and
being in contact with the inclined face of the adjoining ring. If desired the ring
or rings of hard metal are split either straight across or slanting at one place or at
several places and similarly the ring or rings of soft metal are split either straight
across or slanting at one place or at several places but I prefer that the hard metal
ring or rings should not be split and the soft metal ring or rings if split at all
shall be split in such a place or places as not to coincide with any joint or fissure
in the adjacent ring or rings. Adjustment is obtained by forcing the inclined
face or faces of the hard metal ring or rings over the corresponding face of the
adjoining soft metal ring or over the corresponding faces of the adjoining soft
metal rings if a hard metal ring be so situated as to operate on the adjoining faces
of two soft metal rings. The adjustment may take place by means of a gland
surrounding the shaft being forced against the ring adjoining same by means of
bolts and nuts or otherwise. In addition to this said arrangement of rings the
shaft may also be surrounded with a ring or rings of hemp asbestos or the like if
found necessary.

I, REUBEN THOMAS PRESTON, of the Firm of J. Stone & Company, of Deptford,
in the County of Kent, Engineers, do hereby declare the nature of this invention
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 improvements in packing or bearings for reciprocating
and
rovalving rods shafts and tha lil

page_text: According to my invention I mount in the stuffing box or in a casing bracket
or the like one or more rings of comparatively hard metal or material having one
or more inclined faces and one or more rings of comparatively soft metal or
material having one or more inclined faces, the inclined face of one ring coinciding
and being in contact with the inclined face of the adjoining ring.
Figure 1 of the accompanying sheet of drawings represents as an example the
application of my invention to a stuffing box and
Figure 2 is an elevation of one form of ring.
Figure 3 is a similar view of another form of ring and
Figure 4 shows a slightly modified construction of packing.
Referring to Figure 1 it will be seen that I mount in stuffing box a (or it might
be in a bracket or the like) some rings b of for example gun metal or other hard
material and having inclined faces and some rings c of for example white metal
or other comparatively soft material. The rings c have also inclined faces so
that they coincide with the adjacent inclined faces of the rings b. The end of the
gland adjacent to the upper ring b is in this example made to correspond to
the inclined face of the said ring. It is however apparent that a soft metal ring
may be next to the gland instead of a gun metal ring as shown. If desired the
ring or rings of hard or soft metal are split either straight across at one place as
shown in Figure 2 or slanting as shown in Figure 3 or some of the rings may
be split in more than one place but if split at all the rings shall not be put in
place so that the split parts of one ring coincide with the split parts of an adjoin-
ing ring. Adjustment is obtained by forcing the inclined face or faces of the
hard metal ring or rings over the corresponding face of the adjoining soft metal
ring or over the corresponding faces of the adjoining soft metal rings if a hard
metal ring be so situated as to operate on the adjoining faces of two soft metal
rings. The adjustment in the constructions shewn in Figures 1 and 4 is effected
by means of the gland surrounding the shaft e being forced against the ring b
adjoining the same by means of bolts and nuts or otherwise.. As shewn in
Figure 4 in addition to this said arrangement of rings b and c of hard and soft
material respectively the shaft may also be surrounded at one or more places
In this con-
with a ring of hemp asbestos or the like if found necessary.
struction the lowermost hard metal ring marked g is made to conform with the
recess in the stuffing box and has only one inclined face to correspond with that
of the adjoining soft metal ring c.
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:
and
or
1. A packing or bearing for reciprocating revolving rods shafts and the
like consisting of a stuffing box, or casing, a ring or rings of hard metal or
material having one or more inclined faces a ring or rings of soft metal or
material having one or more inclined faces the inclined face of one ring coin-
ciding with the inclined face of an adjoining ring and means for forcing the
rings against each other substantially as set forth.
2. The constructions of packing or bearings as described and shewn on the
drawings.
