AN IMPROVED PACKING FOR PIPE AND OTHER JOINTS
Year: 1885

page_text: I, FRANZ CARL GUILLEAUME, of the firm of Felten and Guilleaume, of Mülheim
on the Rhine, in the Empire of Germany, Wire manufacturers, do hereby declare
the nature of my invention for "AN IMPROVED PACKING FOR PIPE AND OTHER
JOINTS" to be as follows:-
For packing the joints of flange pipes, man- and mud-hole covers on boilers and
other joints where means are provided for tightening together the parts to be
connected, I employ packing rings composed mainly of wires, by preference of the
finer gauges. The body of the packing ring is formed by coiling the wire a con-
siderable number of times, the several coils or strands of the ring being subsequently
fastened together by means of a binding wire or wires. The wire constituting the
coil may be in one length, or in several or many lengths.
The packing ring having been constructed as described is immersed in or served
with a composition of grease or linseed oil with graphite or minium of lead with
the result that the various wires or strands composing the body of the ring become
formed into a coherent mass, which nevertheless retains sufficient elasticity to
render the packing suitable for making a tight joint between surfaces which may
be somewhat uneven.
Other preparations besides those composed of the ingredients mentioned may be
employed without departing from the principle of my invention, according to the
nature pressure or temperature of the Huid contained in the pipe or vessel upon
which the joint is to be made.
In constructing packing rings of my improved type in the form of washers,
whereby increased surface is afforded for making a tight joint, I employ two or
more rings formed in the manner above described but slightly differing in diameter,
so that the external diameter of one ring coincides with the internal diameter of
the next one larger. These having been arranged concentrically are laced together
with wire or other suitable binding material, and the packing ring or washer
thus built up is then treated with a hard-setting composition of the kind before
referred to,

page_text: I, FRANZ CARL GUILLEAUME, of the firm of Felten & Guilleaume, of Mülheim
on the Rhine, in the Empire of Germany, Wire Manufacturers, 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:-
.
For packing the joints of flange-pipes, man- and mud-hole covers on boilers, and
other joints where means are provided for tightening together the parts to be
connected, I employ packing rings composed mainly of wire, by preference of the
finer guages. The body of the packing ring is formed by coiling the wire a con-
siderable number of times, the several convolutions thereof being subsequently
fastened together by means of a binding wire or wires. The wire constituting the
coil may be in one length, or in several or many lengths. Such a packing ring is
represented in plan and cross section in Figures 1 and 2 of the accompanying
drawings.
The packing ring, having been constructed as described, is immersed in or served
with a composition of grease or linseed oil with graphite or minium of lead, with
the result that the various wires or strands composing the body of the ring become
formed into a coherent mass, which nevertheless retains sufficient elasticity to
render the packing suitable for making a tight joint between surfaces which may
be somewhat uneven. The packing ring may, however, be immersed in the com-
position before the coils of wire composing the ring have been served with the
binding wire; it being a matter of comparative unimportance at which stage in
the manufacture the filling material is applied.
Other preparations besides those composed of the ingredients mentioned may be
employed without departing from the principle of my invention, according to the
nature, pressure or temperature of the fluid contained in the pipe or vessel upon
which the joint is to be made.
In constructing packing rings of my improved type in the form of washers,
whereby increased surface is afforded for making a tight joint, I employ two or
more rings formed in the manner above described, but slightly differing in diameter,
so that the external diameter of one ring approximately coincides with the internal
diameter of the next one larger. These having been arranged concentrically are
laced together with wire or other suitable binding material. Such a construction
of washer is represented in plan and cross section in Figures 3 and 4 of the
accompanying drawings. As a modification of this arrangement (which, however,
I regard as less satisfactory) a bundle of wires may be arranged in a spiral form
and afterwards laced or bound together in the manner previously described. .The
packing ring or washer thus built up is treated during the course of manufacture
with a hard-setting but semi-elastic composition of the kind before referred to.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
First :—For pipe and other joints, the improved manufacture of packing sub-
stantially as herein described and composed of one or more wires coiled into a ring,
the numerous convolutions or strands comprised in the ring being wrapped with
binding wire and the whole served with a hard-setting but semi-elastic composition,
as and for the purposes set forth.
Secondly-In the production of packings of the washer type, the use, substan-
tially as described with reference to Figure 3, of two or more rings, such as described
in the preceding claim, arranged concentrically and contiguously and laced or
secured together with binding wire.
