PROVISIONAL SPECIFICATION.
Improvements in Metallic Packing.
J, GEORGE GATES, of 8 Scafell Terrace, York Road, West Hartlepool,
Marine Superintendent, do hereby declare the nature of this invention to be as
follows:-
My improvements in metallic packing relates more particularly to those known
as floating." The improvements are applicable to rods of steam engines, pump
plungers, and rods of every kind requiring packing. My improved packing is
cheap and simple in construction and application; no skill is required in adjusting
it and it greatly reduces the wear on the rods.
In order that my invention may be the more readily understood I make reference
to the two sheets of drawings annexed to this specification, in which

COMPLETE SPECIFICATION.
Improvements in Metallic Packing.
I, GEORGE GATES of 8, Scafell Terrace, York Road, West Hartlepool,
Marine Superintendent, 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 :-
My improvements in metallic packing relate more particularly to those known

as floating." The improvements are applicable to the rods of steam engines,
pump plungers and rods of every kind requiring packing. My improved packing
is cheap and simple in construction and application: no skill is required in adjusting
it and it greatly reduces the wear on the rods.
In order that my invention may be the more readily understood I make reference
to the two sheets of drawings filed with my Provisional Specification in which
Fig. 1 shows a vertical section of the complete packing.
Fig. 2 a plan of the anti-friction cone packing.
Fig. 3. an elevation and Fig. 4 a vertical section of the cone packing and outer
brass cone ring.
Similar letters refer to the same parts in each figure.
a is the piston rod; b the neck bush inch aside larger than the rod :
c anti-
friction cone packing: d outer brass cone: e brass washer between soft
packing k, and anti-friction cone c. f brass washer between the two antifriction
rings c.
g space between the outer diameter of packing and stuffing box. h gland.
k soft packing: 1 tongue of cone c. m space between rod and neck bush;
n space between rod and gland bush; p space between segments for allowing
packing e to go to the rod. s space between the anti-friction cones c. The feature
of the packing is that having an outer ring d in one piece and the ring c in
segments (the latter being tongued) no steam can pass to the walls of the stuffing
box, or pass the gland. The outer ring is inch smaller in diameter than the inner
diameter of the stuffing box thus making it a perfectly reliable floating packing
suitable for bent rods or rods out of line. The inner cones c are made of specially
prepared anti-friction metal. The packing can at all times when engines or
machinery are working be adjusted by screwing up the gland which only requires
to be done slightly to ensure a tight packing and at the same time the friction is
reduced to the minimum. One turn of soft packing k is applied at the bottom to
keep the lubricating material together. The brass ring e is to allow the packing
to work freely and prevent the soft packing getting into the joints in the cone
rings c.
I do not confine myself to the precise configuration relative proportions or dis-
positions of parts described in the above specification or exemplified in the
drawings filed with my Provisional Specification, as any or all of them may be
considerably varied without departing from the spirit of my invention.
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 :-
Metallic packing constructed and operating substantially as described in the
above specification and exemplified in the drawings attached to the Provisional
Specification of this application.
