page_text: We, WILLIAM CROMAR, of Rium Terrace, West Hartlepool, in the County of
Durham, Engineer, and LEVI GARSIDE, Junr., Shawelough, Rochdale, in the
County of Lancashire, Asbestos Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the manufacture of an improved engine packing by
the combination of a specially prepared white metal plug with asbestos and
other materials to form a packing, which is practically indestructible by heat,
is unaffected by water or moisture and built up so as to be very elastic. This
construction renders it particularly suitable for untrue rods and generally for
packing for the stuffing boxes of all kinds of steam hydraulic and other fluid
pressure engines.
In carrying out this invention we take asbestos or any other suitable yarn
and plait or braid it to give the necessary size into which we then place white
metal plugs consecutively so as to get as complete a metal surface as possible
consistent with the circling of the packing on the rod, it is then made water-
proof & built up to the required size by placing asbestos & brass wire cloth or
any other suitable fabric on three or four sides, also when necessary a layer or
layers of rubber can be placed at the back.
To enable our invention to be fully understood we will describe how it can
be carried into practice by reference to the accompanying drawing.
Figure 1 is a section of our improved packing as shown on the face.
Figure 2 is a section through a piece of our packing.
a, represents white metal plugs or special alloy which are placed consecutively
in the centre of the plaited or braided yarn and fastened by clenching, repre-
sents the yarn plaited into a section of the packing; e, represents the asbestos
and brass wire cloth which in this case is placed on three sides of the packing.
In some cases figures a and bare sufficient without the asbestos or any other
cloth covering the important feature about our packing is to get practically
a full metal face to the rod and fastening the plugs so as not to separate from
the asbestos while at the same time allowing the packing to circle down to any
size of a rod with ease.
Dated this Thirtieth day of September 1899.

page_text: County of Lancashire, Asbestos Manufacturer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
or
This invention relates to the manufacture of an improved engine packing
by the combination of metal with asbestos and other materials to form a pack-
ing, which is practically indestructible by heat, is unaffected by water
moisture and built up so as to be very elastic. This construction renders it
particularly suitable for untrue rods and generally for packing for the stuffing
boxes of all kinds of steam hydraulic and other fluid pressure engines.
In carrying out this invention we take asbestos cloth or yarn, or any other
suitable cloth or yarn and plait braid or build up to the necessary size, into
which we then fix a flexible or plaited metal strip by stitching to the cloth or
yarn from the back side so as to get a continuous metal surface which will bend
or circle easily to the rod. The same result may be obtained by wrapping the
metal round a portion or the whole of the cloth or yarn. When necessary a
layer or layers of rubber can be placed at the back.
To enable our invention to be fully understood we will describe how it can
be carried into practice by reference to the accompanying drawings.
Figure 1 is a section of our improved packing as shown on the face with
metal wrapped round a portion of the cloth.
Figure 2 is a section through a piece of our packing with metal wrapped
round a portion of cloth.
Figure 3 is a section of our improved packing with metal fixed on the face.
Figure 4 is a section through a piece of our packing with metal fixed on the
face.
", represents asbestos & brass wire cloth, b, represents metal.
The important feature about our packing is to get a complete metal face to
the rod, while at the same time allowing the packing to circle down to any
size of a rod with ease.
Having now ascertained and particularly described the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Packing for glands with a complete metal surface to the rod.
2. The metal can be of brass lead or any other suitable wire plaited or braided
together.
3. The metal can be wrapped round asbestos or any other suitable material
as Figure 1 & 2.
4. The metal can be fixed to the face of asbestos or any other suitable material
as Figure 3 & 4.
