PROVISIONAL SPECIFICATION.
An Improved Packing for the Stuffing-boxes of Steam Engines and
Pumps, and for Joints requiring to be Made Steam, Air, or
Watertight.
We CHRISTIAN LUDVIG ENGOLF MELSOM and ARTHUR STANLEY
MORRISON both of 24 Duke Street, Aldgate, in the City of London, Engineer
and Merchant respectively, do hereby declare the nature of this invention to be
as follows:-
The packing consists of a ring of white metal or other suitable metal or material,
the inner face of which is placed in contact with the piston rod or plunger, and is
kept up to the rod or plunger by an india rubber cushion, backing or band, which
is attached to the ring in such a manner as to ensure its adhesion to it, and shaped
so that when the gland of the stuffing box is screwed up or tightened, it will
compress the rubber backing and cause it to force the metal part against the rod or
plunger by a lateral action, allowing the force to be varied in extent to suit all
requirements even whilst the engines or pumps are working. The rubber may be.
protected by placing one or more covers of asbestos or other suitable material
round it. The complete ring may be cut in two or more pieces as may be
considered most suitable so that the ring may wear equally and be easily applied.
These rings may be used either by themselves or in connection with other kinds of
packing.
Dated this Sixth day of June 1894.

We CHRISTIAN LUDVIG ENGOLF MELSOM and ARTHUR STANLEY
MORRISON both of 24 Duke Street Aldgate in the City of London, Engineer
and Merchant respectively, 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 :--
A packing according to our invention consists of a ring of any suitable metal or
combination of metals, the inner face of which is placed in contact with the surface
to be packed, and is kept up to the surface to be packed by an india rubber cushion,
backing or band, which is attached to the ring in such a manner as to ensure its
adhesion to it, and shaped so that when the gland of the stuffing. box is screwed up
or tightened, it will compress the rubber backing and cause it to force the metal
part of the ring against the surface to be packed, by a lateral action, allowing the
force to be varied in extent to suit all requirements, even whilst the engines or

more covers of asbestos or other suitable material round it. The complete ring
may be cut in two or more segments as may be considered most suitable so that
the ring may wear equally and be easily applied. These rings may be used either
by themselves or in conjunction with other kinds of packing.
The foregoing being a general description of the nature, object and purposes of
our invention, we will now proceed to set forth the same more clearly by the aid of
one sheet of drawings hereto annexed and which form part of this Specification.
The drawings are marked with figures and letters of reference corresponding with
those in the following.explanation, like letters and figures being used to denote the
same, or corresponding parts throughout the various views and figures.

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that, what,
we claim is
.
First. The improved engine packing hereinbefore described, such packing being
made by attaching an india rubber backing, cushion or band to a metallic ring in
such a manner that a portion of the ring can be adjusted to the surface to be packed
whilst the engines or pumps are working, by simply adjusting the gland of the
stuffing-box in the usual way as set forth and illustrated in the accompanying
drawings.
Dated this 1st day of March 1895.
