I, HENRY JACKSON GOLD, of Broadway House, in the County-town of Warwick,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object the construction of a new or improved compound
metallic packing ring for stuffing-boxes and the like which whilst being manufactured
and applied in the ordinary manner shall be more efficient as a steam and water
tight anti-friction metallic packing ring than other metallic packing rings heretofore
made.
In accordance with this my said invention I construct my compound metallic
packing ring in two parts that is to say of an inner and outer ring the inner ring
being of a soft metal such as "white" or other anti-friction metal and the outer ring
of a hard metal such as gun-metal or brass. The inner periphery of each of the said
inner and outer rings is made eccentric to the outer periphery the diameter of the
outer periphery of the said inner ring corresponding with the diameter of the inner
periphery of the said outer ring in such wise that the said inner ring will fit snugly
within the said outer ring thereby forming a new or improved compound metallic
packing ring having its inner and outer peripheries concentric and the circular joint
between its said component parts eccentric to such peripheries.
The new or improved compound metallic packing ring may have each of its said
component parts suitably cut so as to allow for wear as is well known.

A New or Improved Compound Metallic Packing Ring for Stuffing-
boxes and the like.
I, HENRY JACKSON GOLD, of Broadway House, in the County-town of Warwick,
Engineer, 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 :-
This invention has for its object the construction of a new or improved compound
metallic packing ring for stuffing-boxes and the like.
According to my invention I construct the compound metallic packing ring in two

page_text: parts, an inner ring of a soft metal such as "white" or other anti-friction metal and
an outer ring of a hard metal such as gun-inetal or brass. The inner periphery of
each of the said rings is made eccentric to the outer periphery, and the diameter of
the outer periphery of the inner ring corresponds with the diameter of the inner
periphery of the outer ring, so that the inner ring fits snugly within the outer ring
and forms therewith a compound metallic packing ring whose inner and outer peri-
pheries are concentric but in which the circular joint between the component parts
is eccentric to such peripheries.
The compound metallic packing ring may have each of its component parts
suitably cut so as to allow for wear in the usual manner.
I have illustrated an application of my invention in the accompanying drawings in
which Fig. I is a longitudinal medial section and Fig. II a transverse section on the
line A A of Fig. I.
I have shown a packing comprising two compound rings carried in a casing
which is adapted to fit the stuffing box to which the packing is applied; there
may be two casings and sets of rings fitted in the one stuffing box with an
interposed spiral spring adapted to transmit pressure through the rings to opposite
ends of the stuffing box, after the manner described in the Specification to
Keene's Patent No. 9247 of 1893; or there may be but the one casing and set of
rings with the spring at one end; or the compound rings may be fitted in the
place of ordinary rings according to any of the well known modes of construction
adopted in the case of metallic packings.
1 is the casing which is adapted to hold the rings and to fit in the stuffing box;
the casing has an interually projecting flange 11 whose upper face is bevelled as
shown. The inner ring 2 and the outer ring 3 of the compound ring have their
under faces bevelled to correspond with the flange 11, and where more compound
rings than one are fitted, an intermediate ring such as 4 is placed between adjacent
pairs. Each of the rings 2 and 3 may be split, as shown in the drawings, at the thin
side, so that as they wear they may be closed in by the joint action of the spring and
the bevelled edges, and any suitable means may be provided to prevent relative
rotation of the component parts.
Bearing rings may be fitted between the spring and the compound rings to
uniformly distribute the pressure.
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
An improved compound packing ring for metallic packings and the like consisting
of two eccentric rings so shaped and fitted together as to form a compound ring
having concentric peripheries; substantially as described and illustrated.
