Patent Agent, for the Invention of "A NEW OR IMPROVED METHOD OF TREATING
HOP STALKS IN ORDER TO OBTAIN THE FIBROUS PARTS THEREOF." A com-
unication from abroad by Isaac David Noerdlinger, of Stuttgart, Germany.
PROVISIONAL SPECIFICATION left by the said John William Tasker at the
Office of the Commissioners of Patents on the 8th August 1878.
JOHN WILLIAM TASKER, of Halifax, in the County of York, Patent Agent. "A
NEW OR IMPROVED METHOD OF TREATING HOP STALKS IN ORDER TO OBTAIN
THE FIBROUS PARTS THEREOF." [A communication from abroad by Isaac David
Noerdlinger, of Stuttgart, Germany.]
The object of this Invention is to obtain the fibrous parts of hop stalks which
are long and fine, and may be spun, woven, and used for stuffing furnature and
similar purposes.
The stalks or stems are boiled in water with a little soap and soda in a closed pot
or vessel about three-quarters of an hour; they are then washed in clean water, the
fibres taken off, and again boiled in water about the same length of time as before,
wine vinegar or acetic acid being mixed with the water; finally, the fibres are
washed in clean water and dried. The fibres thus obtained are ready for manu-
facturing, for which purpose they may be submitted to the same processes as other
fibrous substances, namely, hackling, spinning, weaving, bleaching, whilst the waste
is well qualified for the stuffing of furnature, being elastic, soft; and durable.

the said John William Tasker in the Great Seal Patent Office on the 8th
February 1879.
JOHN WILLIAM TASKER, of Halifax, in the County of York, Patent Agent. "A
NEW OR IMPROVED METHOD OF TREATING HOP STALKS IN ORDER TO OBTAIN
THE FIBROUS PARTS THEREOF." A communication from abroad by Isaac David
Noerdlinger, of Stuttgart, Germany.
The object of this Invention is to obtain the fibrous parts of hop stalks which
are long and fine, and may be spun, woven, and used for stuffing furniture and
similar purposes.
The material obtained is very much like the filaments of flax, and excels in
elasticity, softness, and durability, and is moreover very cheap, as at the present
time the hop stalks after the gathering of the crops are burnt on the fields as
worthless, and can be obtained in large quantities in hop-growing districts.
The stalks or stems are to be boiled in water with a little soap and soda in a closed
vat or vessel about three-quarters of an hour; then the stalks so prepared are to be
washed in clear water, the fibres taken off, and again boiled in water mixed with
"wine vinegar" or acetic acid for about the same length of time; finally, the fibres
are to be washed in clear water and then dried. The fibres thus obtained are ready
for manufacturing, for which purpose they may be submitted to the same processes
as other fibrous substances, namely, hackling, spinning, weaving, bleaching, whilst
the waste is well qualified for the stuffing of furniture, being elastic, soft, and
durable.
I claim as my Invention the method of obtaining the fibrous parts of hop stalks,
in manner and for the purpose herein described.
In witness whereof, I, the said John William Tasker, have hereunto set my
hand and seal, this Seventh day of February, in the year of our Lord
One thousand eight hundred and seventy-nine.
