County of Lanark, North Britain, Gentleman, for the Invention of
“IMPROVEMENTS IN THE MANUFACTURE OF ASBESTOS PACKING,' FOR PISTON
AND VALVE RODS, PISTONS, PIPE JOINTS, AND OTHER SIMILAR PURPOSES.”

I, WILLIAM STEBBINS FISH, of Glasgow, in the County of Lanark,
North Britain, Gentleman, do hereby declare the nature of the said
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF ASBESTOS PACKING,' FOR
PISTON AND VALVE RODS, PISTONS, PIPE JOINTS, AND OTHER SIMILAR PURPOSES,” to
be as follows, that is to say :-
This Invention relates to improvements in the manufacture of
"asbestos packing," used in the stuffing boxes of piston and valvo rods
for packing pistons, as well as for making pipe joints, also man hole door

page_text: joints, and which may be employed in other situations where such
packing is required or used, consists as follows :—
Under one mode of making the improved packing, strips, fibres, or
slivers of asbestos or amianthus paper are placed parallel to each other,
and confined together by winding or braiding cord or thread composed
of asbestos or amianthus or other fibrous material around them, or by
encasing them within a knitted or plaited cover.
Under another mode the strips or pieces of asbestos or amianthus
paper are rolled or twisted into strings or cords, which aro plaited,
twisted, or braided into a rope or sliver of any desired size or shape, or ]
the strips or pieces of asbestos or amianthus paper or strings or cords
composed thereof may be rolled or twisted around a core composed of
india-rubber, cork, wood shavings, wire, or paper, made cither of asbestos
or other paper stock, or the core may be composed of fibres of asbestos
laid loosely or compressed or twisted together.
The asbestos or amianthus paper employed in making the improved
packing may either be used alone, or the paper may be coated with
caoutchouc or gutta percha, which may or may not be vulcanized, or it
may be coated with animal, vegetable, or mineral oils, or with gummy,
or farinaceous, or glutinous matters, which may be applied to the paper
or cords composed thereof, either previous to or during the time the
packing is being made.

NOW KNOW YE, that I,' the said William Stebbins Fish, do hereby.
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :--`
My said Invention relates to improvements in the manufacture of
"asbestos packing," used in the stuffing boxes of piston and valvo rods,
for packing pistons, as well as for making pipo joints, also man hole door
joints, and which may be employed in other situations where such
packing is required or used, consists as follows:-
Under one modo of constructing the improved packing strips, fibres, or
slivers of asbestos or amianthus paper, or millboard or pasteboard formed
of asbestos or amianthus, aro placed parallel to each other, and confined
together by winding or braiding cord or thread composed of asbestos or
amianthus or other fibrous material around them, or by encasing thom.
O within a knitted or plaited cover.
Under another modo of constructing the improved packing tho strips
or pieces of asbestos or amianthus paper, millboard, or pasteboard, are
rolled, twisted, or pressed into strings or cords, which are again plaited,
twisted, or braided into a rope or sliver of any desired size or shapo, or
5 the strips or pieces of asbestos or amianthus paper, or strings or cords
composed thereof, may be rolled or. twisted around a coro composed of

page_text: india-rubber, cork, wood shavings, wire, or paper, made either of asbestos
or other paper stock, or the core may be composed of fibres of asbestos
laid loosely or compressed or twisted together.
The asbestos or amianthus paper employed in making the improved
packing may either be used alone, or the paper may be coated with 5
caoutchouc or gutta percha, which may or may not be vulcanised or it

claim as the Invention secured to me by the herein-before in part recited 1
Letters Patent is, the constructing of asbestos or amianthus packing
according to the several modes herein-before described.
In witness whereof, I, the said William Stebbins Fish, have here--
unto set my hand and seal, this Tenth day of September, One
