WHEREAS by certain Letters Patent under the Great Seal of Great
Britain, bearing date at Westminster, the Eighteenth day of December last,
reciting that I, the said Thomas Crawford, had, by much labour, study, and
application in trying many experiments, invented and brought to perfection
"AN ENGINE FOR WINDING SILK, THREAD, AND YARN, AND WHICH WOULD WIND
AND FRAME SILK AT ONE MOTION AND AT THE SAME TIME, AND WOULD ALSO WIND
SILK, THREAD, AND YARN SINGLE, DOUBLE, AND IN SEVERAL THREADS TOGETHER AT
ONE AND THE SAME TIME, THE CONSTRUCTION AND POWER OF WHICH ENGINE PAR

MANNER OF OBSTRUCTIONS WHICH COULD ARISE FROM THE SEVERAL THREADS
ENTANGLING WITH EACH OTHER;" and that in regard I had been at great trouble
and expence in bringing such new Invention to perfection, I had prayed His
said Majesty would be pleased to grant unto me, my exors, admors, and
assigns, His Majesty's Royal Letters Patent, under the Great Seal of Great
Britain, for the sole use and benefit of my said Invention, within that part of

Dominion of Wales, and Town of Berwick-upon-Tweed, that, during the con-
tinuance of the said term of fourteen years thereby granted, they did, neither

counterfeit, imitate, or resemble the same, without the licence or consent of
me, the said Thomas Crawford, my exors, adiñors, or assigns, in writing under
my hand and seal, first had and obtained. In which said Letters Patent is
contained a proviso that if the said Thomas Crawford shall not particularly
