PROVISIONAL SPECIFICATION.
Improvements in and relating to Flexible Packing Plates, Rings
and the like.
I, ALFRED CALMON, of No. 4 Moorweidenstrasse, in the City of Hamburg, in the
German Empire, Manufacturer, do hereby declare the nature of this invention to
be as follows.
The present invention relates to improvements in and relating to flexible pack-
ing plates, rings, and the like, and the object of the improvements is to procure
a packing which combines in itself the advantages of the two most successful
packing materials-asbestos or like flexible matter and metal; and with this end
in view my invention consists of the hereinafter described combination of such
materials.
My improved packing plate or ring is preferably, composed of a suitably shaped
and solutioned asbestos fabric, asbestos millboard, or like flexible substance. This
is armour-plated or sheathed on both sides with a suitable metallic cover or with
sheet metal.
The manufacture of my improved packing plates may be carried out in the
following manner.
Asbestos millboard, asbestos fabrics, sheets of india-rubber, leather, fibres, or the
like flexible materials are coated by hand or by means of a spreading machine
with a rubber or other solution adapted to resist to the destructive influences of
steam. Upon both sides of the thus prepared flexible plates, are then rolled foils
or sheets of zinc, tin, lead, copper, brass, or an other suitable metal or alloy. The
pressure exerted by rollers or a rolling device makes the sheets of metal stick
firmly to its flexible gummed packing plate and they are reliably united with the
latter after the solution has dried.
A still more reliable junction of the metal sheets and the flexible material, may
be effected by heating the latter after the metal sheets have been rolled thereon,
in or under a suitable vulcanizing press.
Packings of other shape or configuration may, preferably, be made by cutting
or stamping them out of metal sheathed flexible material prepared in accordance
with my invention as above described.

ascertained in and by the following statement.
The present invention relates to improvements in and relating to flexible pack-
ing plates, rings, and the like, and the object of the improvements is to procure
a packing which combines in itself the advantages of the two most successful
packing materials-asbestos or like flexible matter and metal; and with this end
in view my invention consists of the hereinafter described combination of such
materials.
My improved packing plate or ring is preferably, composed of a suitably shaped
and solutioned asbestos fabric, asbestos millboard, or like flexible substance. This
is armour-plated or sheathed on both sides with a suitable metallic cover or with
sheet metal.
The manufacture of my improved packing plates may be carried out in the
following manner.
Asbestos millboard, asbestos fabrics, sheets of india-rubber, leather, fibres, or the
like flexible materials are coated by hand or by means of a spreading machine
with a rubber or other solution adapted to offer resistance to the destructive
influences of steam. Upon both sides of the thus prepared flexible plates, are
then rolled foils or sheets of zinc, tin, lead, copper, brass, or other suitable metal
or alloy. The pressure exerted by rollers or a rolling device makes the sheets
of metal stick firmly to its flexible gummed packing plates and they are reliably
united with the latter after the solution has dried.
A still more reliable junction of the metal sheets and the flexible material, may
be effected by heating the latter after the metal sheets have been rolled thereon,
in or under a suitable vulcanizing press.
Packings of other shape or configuration may, preferably, be made by cutting
or stamping them out of metal-sheathed flexible material prepared in accordance
with my invention as above described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
Flexible packing plates, rings and the like, consisting of asbestos millboards,
asbestos fabrics, India rubber sheets fibres or like flexible materials impregnated
with a suitable rubber solution or not, and armour-plated or sheathed on one or
both sides with a suitable metallic foil, or sheet metal cover, substantially as and
for the purpose set forth.
