page_text: nature of my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His Majesty's High Court of Chancery
within two calendar months next immediately after the date of the said recited
Letters Patent, as in and by the same, reference being thereto had, will more
fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Bartlett, do hereby describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by the following description
thereof (that is to say) :-
That it consists in the application of the tanning principle to the flax thread
or yarn, so that the said flax thread or yarn, having imbibed the tanning
principle, is rendered more durable and less liable to rot or decay by exposure
to alternate wet and dry.
The method I adopt for applying the tanning principle is by steeping or
boiling the flax thread or yarn in a decoction or infusion of oak bark, or other
substance which contains the real tanning principle; the flax thread or yarn,
being then properly dried, and becomes fit for use. If the infusion or decoction
is prepared of adequate strength, one steeping or boiling the flax thread or yarn
will be sufficient, otherwise the operation must be repeated, drying the flax
thread or yarn each time.
I claim the exclusive right of preparing flax thread or yarn by tanning,
or by applying the tanning principle to the said flax thread or yarn, for use
in the manufacture of boots, shoes, saddlery, and of sail and other cloths or
bagging.
In witness whereof, I have hereto set my hand and seal, the Sixth day
of August in the woon of our Lowd One thousand sight hundred and
n the High Court of
AND BE IT REMEMBERED, that the said John Bartlett came before our
Lord the King in His Chancery, and acknowledged the Specification aforesaid,
and all and every thing therein contained, in form above written. And also
the Specification aforesaid was stamped according to the tenor of the Statute
in that case made and provided.
