PROVISIONAL SPECIFICATION.
Improvements in Piston Rod and other Packing.
I, ASPLAN BELDAM, of 77, Gracechurch Street, in the County of London,
Engineer, do hereby declare the nature of this invention to be as follows:
-
My invention has for its object certain improvements in packing, suitable for
stuffing boxes and other working joints or moving parts of engines, pumps, or
machines in which steam or other fluids under pressure are employed or operated
upon or in connection with which the pressures are externally exerted.
A packing provided with improvements according to this invention comprises one
or more tubes or hollow or tubular pieces of white metal, brass, or other suitable
material, which, when the packing is made up, lie around or otherwise in the part
to be packed, and such tubes are provided with openings or a continuous opening
at the part which lies next the rod or other surface. The interiors of the tubes or
hollow pieces serve to catch or hold a lubricant, and thus act to some extent as
lubricators.
In some cases when a tube or tubes is or are used in the packing, a groove or
recess may be made therein and the tube inserted in said groove or recess.
The openings in the tubular part may be formed therein in any suitable way,
such for instance as a slot or slit, or a plurality of same, or by perforations.
The tubes or tubular packing can be combined with other metallic packings,
asbestos packings, or packings made from other substances or materials, and the
tube or tubes can be held in place by adhesive compounds or rivetted, screwed, or
otherwise equivalently secured to the material in connection with which it or they
are used.
In some cases the tubes or hollow pieces may lie around the rod or in others they
may be placed endwise or longitudinally and held in asbestos or other packing
material in which they may be held by being driven in, by clenching, rivetting or
other suitable means.
This invention is not confined to any particular material or materials of which it
may be made, or to any particular forms, as these will necessarily vary according
to requirements and purposes to which the invention may be put.

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 :-

In some cases when a tube or tubes is or are used in the packing, a groove or

In some cases the tubes or hollow pieces may lie around the rod; or, in others,
they may be placed endwise or longitudinally, and held in asbestos or other
packing material, in which they may be held by being driven in, by clenching,
rivetting, or other suitable means.
-
This invention is not confined to any particular material or materials of which
it may be made, or to any particular forms, as these will necessarily vary
according to the requirements and purposes to which the invention may be put.
That this invention may be clearly understood it will now be described with
reference to the annexed drawings which illustrate the invention, and which together
with the following description will be sufficient to enable others skilled in the art to
which it belongs to make and use the same. The drawings are marked with figures
and letters of reference corresponding with those used in the following explanation.
Like letters are used to denote the same or corresponding parts throughout the
several figures.
DESCRIPTION OF THE DRAWINGS.
Figures 1, 2 and 3 illustrate examples of packing provided with the improvements
according to this invention in which the metal tubes lie around the part to be
packed. The figures show three layers of packing in a stuffing box one half of the
box only being shown and the rod being shown in dotted lines.
Figures 4 and 5 illustrate examples of the packing in which the tubes are
arranged at right angles to the rod to be packed, or end wise in the packing.
Figures 6, 7 and 8 illustrate modifications of the arrangement of the tubes in the
packing.
With reference to the drawings a designates a portion of a stuffing box, and 6 the
rod to be packed; c is the body of the packing, which may be asbestos packing, or
a packing made of fibrous, woven, textile, or other suitable material; d are the
metal tubes which according to this invention are placed or made up in the packing.
The metal tubes & may, in some cases, be made up or placed in the body c of the
packing so as to lie around the part to be packed, the tubes being provided with
holes as shown in Figure 1, or slots d' as shown in Figure 2; or half tubes may
be used as shown in Figure 3, the holes or open part of the tube being next to the
rod to be packed. Or, instead of causing the metal tubes d to lie around the part
to be packed, they may be placed at right angles or end wise as shown at
Figures 4 and 5, the tubes being clenched or otherwise fastened into the
packing. These tubes d may be of any suitable section, for instance, they may
be circular, as shewn in Figure 6, flattened as in Figure 7, or oval as in Figure 8,
and they may be placed in the packing with respect to the face thereof, in any
suitable way.
A packing according to my invention will resist high pressures and temperatures,
and will also be self-lubricating, the tubes d providing a means for holding the
lubricating material.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed what is claimed is :-
1. A piston rod or other analogous packing consisting of material such as specified
having one or more metal tubes, channels or ways provided in it; substantially in
the manner and for the purposes specified.
2. The packings particularly as set forth with reference to and shown in the
different figures of the drawings for the purposes specified.
