PROVISIONAL SPECIFICATION.
Improvements in Joint Making Packing.
We JOHN JAMES ROGERS of 4 De la Bêche Street Swansea in the County of
Glamorganshire, Marine Engineer and ARTHUR EDWIN MILLS of The Chestnuts
Wick near Bath in the County of Gloucestershire, Marine Engineer do hereby
declare the nature of our invention to be as follows:-
A new and reliable high pressure steam and water flange jointing.
For this purpose we use a sheet of gauze wire on one or both sides of which are
pressed or cast or secured in any other convenient manner narrow strips made of
lead or an alloy thereof forming rectangular or other shaped figures for the insertion
of any substance such as red lead, rubber, asbestos, or other suitable material; the
lead strips or strips made of an alloy thereof being elevated above the gauze wire
and of any convenient shape in order to prevent the before mentioned substances
from being forced out by the pressure of the gases or fluids acting on the joint and
also to allow the red lead or other substance to set under pressure.
The gauze wire may be made of copper or any other suitable metal or metals or
combination thereof and woven in the usual manner and may itself contain the
narrow strips made of lead, or an alloy thereof.

We, JOHN JAMES ROGERS of 4 De la Bêche Street, Swansea, in the County of
Glamorgan, Marine Engineer, and ARTHUR EDWIN MILLS of The Chestnuts,
Wick, near Bath, in the County of Gloucester, Marine 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:—
Our invention consists of an improved packing for the flanged joints of steam,
water or other pipes or chambers and is particularly suitable for use where high
pressure fluid is employed, easily adapting itself to unplaned or uneven surfaces
thus effectually preventing the escape of steam or other fluid, and at the same time
remaining perfectly secure within the joint.
On the accompanying sheet of drawings which illustrate one form of our improved
packing,
Figure 1 is a plan of one form of said packing,
Figure 2 the same when shaped to fit a flange pipe or cylinder cover joint.
Figure 3 is a vertical section through line x-y, (Fig. 1), and
Figure 4 is a plan of a portion of our improved packing arranged for a rectangular
joint such as the cover of a steam valve chest.
In order to carry out our invention we take a sheet of gauze wire, preferably of
copper, and on one or both sides of the same we press, cast or secure in any con-
venient manner narrow ribs or strips made of lead or any alloy thereof or other
[Porno 77

page_text: suitable metal or combination forming patterns of rectangular form as shown
by A A A in the accompanying figures or of any other shape or pattern regular or
irregular according as may be found most convenient. Within the spaces or
cells B B B enclosed by the lead or like strips we insert red lead, rubber, asbestos
or the like which on the joint being tightened up may set under pressure and thus
be prevented from being blown or forced out. The lead or its equivalent in the
form of thin strips may be placed on one or both sides of the gauze wire C
(Fig. 3) and by reason of its pliable nature will adapt itself readily to the faces of
the joint when tightened up. The gauze wire may be of copper or any other
suitable metal or metals or combinations thereof and woven in the usual manner or
if desired may itself contain the narrow strips of lead or the like. Our packing
may be made in sheets of any convenient size as shown in Figure 1 and cut or
punched to the required shape as for a pipe or cylinder as shown in Figure 2, or
may be cut into strips of suitable width when required for valve boxes or the like
as indicated by Figure 4.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A joint packing consisting of a web or diaphragm of thin material preferably
metallic gauze as shown by C, Figure 3, on one or both sides of which are secured
strips or ribs of thicker material preferably lead such as A A A arranged so as to
leave cells or spaces between them such as B B B in which cells or spaces any
filling such as red lead, rubber, or other suitable material may be compressed by
the screwing up of the flanges or faces between which the packing is placed,
substantially as hereinbefore described with reference to the accompanying
drawings.
2. The joint packing constructed substantially as hereinbefore described with
reference to the accompanying drawings.
