PROVISIONAL SPECIFICATION.
Improvements in Asbestos and other Textile Packing for Stuffing
Boxes and similar purposes.
I, FRANK ARTHUR WAYLEN, of 15, Gratton Road, Addison Road, in the
County of Middlesex, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention has for its object the production of asbestos or other textile packing
having a longitudinal passage through it so as to admit of the flow of lubricant
into the interior thereof, while at the same time the packing is rendered of a
permanently elastic nature. For this purpose I employ a helically wound wire
core round which I either coil or plait the asbestos or other cloth forming the packing
until the required thickness has been obtained, or I insert the core into tubular
woven packing of the required thickness or I weave the tubular packing on to the
core.
By this means I produce a packing having a central passage through it, into
which the lubricant can readily penetrate and from which it can pass through the
spaces between coils of the core into the body of the packing. At the same time
the wire coil constitutes a spring affording permanent elasticity to the packing, as.
the wire coil is unaffected by the heat to which stuffing boxes are subjected.

Improvements in Asbestos and other Textile Packing for Stuffing
Boxes and similar purposes.
1, FRANK ARTHUR WAYLEN, of 15, Gratton Road, Addison Road, in the
County of Middlesex, 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 :-
My invention has for its object the production of asbestos or other textile
packing having a longitudinal passage through it so as to admit of the flow of
lubricant into the interior thereof, while at the same time the packing is rendered
of a permanently elastic nature. For this purpose I employ a helically wound wire
core round which I either coil or plait the asbestos or other cloth forming the
packing until the required thickness has been obtained, or I insert the core into.
tubular woven packing of the required thickness or I weave the tubular packing on
to the corc.
By this means I produce a packing having a central passage through it, into
which the lubricant can readily penetrate and from which it can pass through the
spaces between coils of the core into the body of the packing. At the same time
the wire coil constitutes a spring affording permanent elasticity to the packing, as
the wire coil is unaffected by the heat to which stuffing boxes are subjected.
Figs. 1 and 2 of the accompanying drawings shew a side view and cross section
of a length of packing constructed according to my said invention in which the
helically wound wire core a has a length of asbestos or other fabric wound round
it to the required thickness, the outer end being secured by cementing or otherwise.
Figs. 3 and 4 shew similar views of a packing in which the helical wire core a is
encased in several separate tubes of asbestos or other fabric b b formed by successive
plaitings or tubular weavings round the core.

page_text: In both cases a central passage c is formed into which the lubricant can readily
enter and from which it can penetrate between the open coils of the core into the
body of the packing.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Constructing asbestos or other textile packing with a longitudinal passage
through it formed by a helically wound wire core, substantially as described.
