HECTOR AUGUSTE DUFRENÉ of N° 10, rue de la fidélité, Paris, and 4, South
Street, Finsbury, London, Civil Engineer [and Patent Agent] "A PROCESS FOR
"
THE MANUFACTURE OF PAPER PULP, PAPER, TEXTILE FABRICS, CORDAGE AND THE

munication from Monsieur Henrique da Costa Corrêa Leite a person resident at
N° 9, rue Condé, Paris, in the Republic of France]
" or
The first
The invention communicated to me relates to a new mode of manufacturing the
constitutive elements of paper pulp, paper, textile fabrics, cordage and the like.
For this purpose I employ the steins, leaves, and roots of the "galega orientalis
of the "galega officinalis" either when in a green or in a dry state.
preparation is the same for the manufacture of paper as for the manufacture of
cordage or tissues excepting that when preparing paper pulp I commence by
cutting the plant into pieces. The plant, either cut into pieces or whole, is placed
in a boiler full of water containing from five to ten per cent of carbonate of potash,
the whole is left in this state either cold or hot under a pressure a little greater
than atmospheric pressure. The operation lasts about two hours. To produce
textile fibres for tissues or cordage the plant thus disaggregated is converted into
flax-like fibres by the ordinary process in order to be afterwards spun, woven, or
twisted. If it is required to make paper the fibres are placed in a pulp vat
together with some chloride of lime and a small quantity of sulphuric acid. A clear
and resistant pulp is thus obtained which can be employed, either alone or mixed,
for the manufacture of paper by ordinary known means.

For this purpose I employ the stems, leaves and roots of the "galega orientalis" or
of the "galega officinalis" either when in a green or in a dry state. The first
preparation is the same for the manufacture of paper as for the manufacture of
cordage or tissues excepting that when preparing paper pulp I commence by cutting
the plant into pieces. The plant either cut into pieces or whole, is placed in a
boiler full of water containing from five to ten per cent of carbonate of potash, the

together with some chloride of lime and a small quantity of sulphuric acid.
A clear and resistant pulp is thus obtained which can be employed, either alone or

Having thus described the invention communicated to me and the manner of
perforining the same what is claimed and intended to be protected by the herein in
part recited Letters Patent is:-
The manufacture of paper pulp, paper, textile fabrics, cordage and the like from
the Galega Orientalis and Galega Officinalis substantially by the process herein
