IMPROVEMENTS IN PACKING FOR STEAM AND OTHER ENGINES AND IN THE PROCESS FOR MAKING THE SAME to be as follows:
Year: 1884

page_text: the Frocess for making the same.
I, ALFRED ALBUTT, of the General Patent Office, N° 4, South Street, Finsbury,
in the County of Middlesex, Mechanical Draughtsman do hereby declare the
nature of the said invention for "IMPROVEMENTS IN PACKING FOR STEAM AND
OTHER ENGINES AND IN THE PROCESS FOR MAKING THE SAME to be as follows:-
"
This invention relates to improvements in packing, made of sisal hemp, aloe,
and similar hard fibrous materials, for steam and other engines and in the process
for making the same.
The toughness of sisal hemp, aloe, and similar fibre has hitherto prevented the
use of such materials for the manufacture of engine packing. By this improved
process, the said fibres are rendered suitable for such purposes.
The process consists in first making a wash, of equal parts of soap and mineral
oil; this wash is then heated and the fibrous substances are thoroughly washed or
soaked therein by being worked with a dolly or the like.
By these means the fibre is rendered so pliable that it can be easily manufactured
into steam packing material and utilised for that purpose in place of cotton, with
tale, plumbago, and the like as hitherto used.
For the purpose of rendering the fibrous material pliant, potash, borax, soda, or
other similar solvents may be used, instead of the wash, composed of soap and
mineral oil as above mentioned.

I ALFRED ALBUTT of the General Patent Office, No 4, South Street, Finsbury,
in the county of Middlesex Mechanical Draughtsman do hereby declare the nature
of the said invention for IMPROVEMENTS IN PACKING FOR STEAM AND OTHER
ENGINES AND IN THE PROCESS FOR MAKING THE SAME (a communication from
abroad by Messrs Wirth & Co of Frankport-on-the-Main in the Empire of Germany
acting as Agents for Messrs Hecker and Becker of Mayence in the Empire of
Germany) and in what manner the same is to be performed to be particularly.
described and ascertained in and by the following statement:-
This invention relates to improvements in packing, made of sisal hemp, aloc and
similar hard fibrous materials, for steam and other engines and in the process for
making the same.
The toughness of sisal hemp, aloe, and similar fibre has hitherto prevented the
use of such materials for the manufacture of engine packing. By this improved
process the said fibres are rendered suitable for such purposes.
The process consists in first making a wash, of equal parts of soap and mineral
oil; this wash is then heated and the fibrous substances are thoroughly washed or
soaked therein by being worked with a dolly or the like.
By these means the fibre is rendered so pliable that it can be easily manufactured
into steam packing material and utilised for that purpose in place of cotton, with
talc, plumbago, and the like as hitherto used.
"
For the purpose of rendering the fibrous material pliant, potash, borax, soda, or
other similar solvents may be used, instead of the wash composed of soap and
mineral oil as above mentioned.
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 herein described process whereby sisal hemp, aloe, and similar fibrous
materials are rendered suitable for the manufacture of packing for steam engines,
by giving such fibrous materials the required degree of pliability, the said process
consisting in steeping and thoroughly dollying such fibrous materials in a heated
wash consisting of about equal parts of soap and mineral oil substantially as
herein before described.
2. The manufacture and use of the improved packing for steam and other
engines such packing being made from sisal hemp, aloe, or similar fibrous substances
substantially in the manner hereinbefore described.
