I, JESSIE ETHEL TURNER, of The Hawthorns, 237, Hawthorn Road, Bootle, in
the County of Lancaster, India Rubber Manufacturer and Merchant, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object a species of packing adapted more especially
for making pipe, man-hole or other joints, where there are two Hat or abutting faces
to be jointed together. It is also designed for packing pistons, stuffing boxes
etcetera.
In carrying the invention into effect I provide one or more cores of metal prefer-
ably of flexible material such as lead or soft brass. These cores are made in the
form of a ring, being stamped out of the metal sheet, or moulded, as found most
convenient. These rings, are covered or surrounded with asbestos and the ring
while strengthening the packing enables it to be bent in the requisite shape. The
asbestos and ring are covered with a thin casing of india-rubber or like material
which is adapted to give to the packing great elasticity and at the same time pro-
tect the asbestos from the action of water. The packing thus formed is not affected
by heat or cold and does not deteriorate by keeping, and being soft and pliable
adapts itself to the irregularities of the surface, and will withstand great pressure.
The asbestos is fastened in position by winding it round the ring or it may be
further secured by twine yarn asbestos thread or by metal wire. The india-rubber
is put on by saturating the asbestos with a solution of india-rubber or by spreading
it on by a brush or otherwise. The ring may be surrounded by cotton yarn or
other textile material instead of asbestos.

ment:
This invention has for its object a species of packing adapted more especially
for making pipe, man-hole or other joints, where there are two Hat or abutting faces
to be jointed together. It is also designed for packing pistons, stuffing boxes,
etcetera.
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which:-
-
Figure 1 shows one form of my improved packing ring;
Figure 2 the same with a piece cut out to show the interior core.
Referring to these figures, I provide a core A (or cores) of metal, preferably of
soft or flexible material such as lead or soft brass. These cores are made in the
form of a ring, being stamped out of the metal sheet or moulded as found most
convenient. They are covered or surrounded with asbestos and the ring whilst
strengthening the packing enables it to be bent in the requisite shape. The
asbestos and ring are covered with a thin casing of indiarubber B or like material
which is adapted to give to the packing great elasticity, and at the same time
protect the asbestos from the action of water. The packing thus formed is not
affected by heat or cold and does not deteriorate by keeping, and being soft and
pliable adapts itself to the irregularities of the surface and will withstand great
pressure. The asbestos is fastened in position by winding it round the metal core A,
or it may be further secured by twine, yarn, asbestos thread or by metal wire. The
indiarubber is put on by saturating the asbestos with a solution of indiarubber or
by spreading it on by a brush or otherwise. The ring may be surrounded by
cotton yarn or other textile material instead of asbestos. The packing thus formed
is not affected by heat or cold and does not deteriorate by keeping.
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:-
1. The improvement in packings, joints, washers or the like for pipe, manhole
and other joints which consists in forming them with one or more cores of soft or
flexible metal covered or surrounded with asbestos, cotton yarn or the like, and
the whole covered with a thin casing of indiarubber or like material adapted to
give the packing great elasticity, and at the same time protect the asbestos from the
action of water.
2. The manufacture of indiarubber packings, joints, washers or the like for pipe,
manhole and other joints with asbestos-covered flexible metallic cores, substantially
us set forth.
