In Article of Manufacture from the Bark of a Certain Tree,
being a Textile Material Applicable for Use in Textile Manu-
factures, including Lint and Wood Wool, and Process Employed
We HENRY JOHN SIMPSON and GRANVILLE DE MONTMORENCY MACKIRDY, both of
7 Rumford Street, Liverpool, in the County of Lancaster, Merchants and ANDREW
TAYLOR, of 11 Lutton Place, Edinburgh, in the County of Midlothian, North Britain,
Chemist do hereby declare the nature of the said invention to be as follows:-
Heretofore the bark of the Californian Red Wood Tree (Sequoia Sempervirens)
which is of exceptional length and thickness has been virtually a waste substance and
of no known industrial value.
The object of this invention is to render it a useful and valuable article. To this
end an examination of and experiments with the bark were made resulting in the
discovery that immediately below the outer bark and the inner portion of the main
bark there exists a fine bast fibre well adapted for use in the textile manufactures
including surgical lint and wood wool. These latter textile articles are especially
applicable in surgery having a particular chemical adaptability for this purpose.
The bast fibre is of great length and is already divided into filaments.
The process and method according to this invention for obtaining the bast fibre
from the bark is as follows. The outer rough bark is separated from the rest of the
main bark by a mechanical contrivance so designed that the great length of fibre
distinguishing this tree may be preserved so far as is consistent with practical
requirements in manufacturing.

page_text: The bast fibre may be now removed, by mechanical means or by steeping in a
suitable chemical solution.
To preserve the length of the fibre as far as is practical we cut the bark into lengths
of convenient size.
The bast fibre thus obtained may be treated in or by any of the known methods or
process or machinery employed in the textile manufactures and used for making
wood wool, lint and textile goods of various descriptions and applied to any suitable
purpose.

being a Textile Material Applicable for Use in Textile Manu-
factures, including Lint and Wood Wool, and Process Employed
We, HENRY JOHN SIMPSON and GRANVILLE DE MONTMORENCY MACKIRDY, both of
7 Rumford Street, Liverpool, in the County of Lancaster, Merchants, and ANDREW
TAYLOR, of 11 Lutton Place, Edinburgh, in the County of Midlothian, North Britain
Chemist, do hereby declare the nature of the said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
Heretofore the bark, of the Californian Red Wood tree (Sequoia Sempervirens)
which is of exceptional length and thickness, has been virtually a waste substance and
of little known industrial value.
The object of this Invention is to render it a useful and valuable article. To this
end an examination of, and experiments with the bark were made resulting in the
discovery that immediately below the outer bark and the inner portion of the main
bark there exists a fine bast fibre well adapted for use in the textile manufactures
including surgical lint and wood wool. We have also discovered that much of the
bark as well as the fine bast fibre above mentioned may be prepared so as to be used
as a textile material for manufactures. This latter textile article is especially
applicable in surgery having a particular chemical adaptability for this purpose.
The bast fibre is of great length and is already divided into filaments.
The process and method according to this Invention for obtaining the useful fibre
from the bark is as follows. The outer rough bark is separated from the rest of the
main bark by suitable mechanical implements so designed that the great length of the
fibre distinguishing this tree may be preserved so far as is consistent with practical
requirements in manufacturing.
The bast and inner fibre may be now removed by mechanical means, or by steeping
in a suitable chemical solution as practised in like industries.
To preserve the length of the fibre as far as is practical, we cut the bark into lengths
of convenient size.
The fibre thus obtained may be treated in or by any of the known methods, or
processes or machinery employed in the textile manufactures and used for making
wood wool, lint cartridge, or blasting fuze and textile goods of various descriptions
and applied to any suitable purpose.

page_text: Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The manufacture herein described for the purposes herein specified consisting of a
textile material, produced from the bark of the Californian Redwood tree (Sequoia
Sempervirens) substantially as set forth.
