CRANFIELD, of Ilminster, in the County of Somerset, send greeting.
THOMAS
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of May,
in the fifty-first year of His reign, give and grant unto me, the said Thomas
Cranfield, my exors, adññors, and assigns, His especial licence, full power,
sole privilege and authority, that I, the said Thomas Cranfield, my exors,
adiñors, and assigns, should and lawfully might, during the term of years
therein expressed, make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "AN IMPROVEMENT UPON
MACHINES FOR SPINNING AND ROVING OF COTTON, FLAX, Tow, HEMP, WOOL, AND
SILK, AND TWISTING OF THREAD;" in which said Letters Patent there is contained a
proviso that if I, the said Thomas Cranfield, shall not particularly describe and
ascertain the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, and cause
the same to be enrolled in His Majesty's High Court of Chancery within two
calendar months next and immediately after the date of the said recited Letters
Patent, that then the said Letters Patent, and all liberties and advantages what-
soever thereby granted, shall utterly cease, determine, and become void, as in and
by the said recited Letters Patent, relation being thereunto had, may more
fully and at large appear."

page_text: NOW KNOW YE, that in compliance with the said proviso, the said
Thomas Cranfield, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained as follows, that (is to say):-
In the well known spinning, roving, or twisting machinery which consists
of one or more spindles, mounted or set in that part of the frame called the
spindle rail, having each of the said spindles fitted up or provided with a
bobbin, which is in contact with the shank of the spindle, which revolves
within it, and also in contact, as to the lower part of the said bobbin, with
the coping rail or bobbin lifter, in consequence whereof each of the said
bobbins is turned round by the action or pull of the thread and rub of the
spindle belonging to the same, and is at the same time retarded or kept
back so as to wind the thread upon the bobbin by the resistance produced
from the friction upon the bobbin lifter and against the surrounding air. Now
in the well known machinery aforesaid, I say, I do affix upon the coping rail or
bobbin lifter thereof, or upon one or more metallic plates attached thereto, one
or more sockets or tubes, thro' and in which the said spindles are severally
passed and do freely revolve; and I make each of the said sockets or tubes
of a fit length to receive and retain the said bobbins in their respective places
or situations, with liberty to revolve as before, and to rise and fall by the
action of the bobbin lifter, but not in contact with the spindle. I do further
declare, that the principal advantages of my said improvement are, that because
the bobbin so placed upon the socket is carried round by the pull the thread
only without any friction or unsteady tremulous action from the spindle, the
thread is less liable to break; and because whensoever any one thread does
break, the bobbin belonging to that thread does not continue to revolve but
stops immediately, the breaking of other threads which commonly takes place
in the old machine from the tail of the broken thread striking and breaking
the others in its vicinity, does not ensue, and that accordingly from the said
steady and duly formed action, and from the less quantity of time being lost
by stopping the several parts of the machine when accidents do happen, the
quantity of work performed is greater, and the machinery can be kept in
action for a longer time and with greater speed than is commonly used in
performing work of the like nature.
In witness whereof, I, the said Thomas Cranfield, have hereunto set my
hand and seal, this Third day of July, in the year of our Lord One
thousand eight hundred and eleven.
THOMAS CRANFIELD. (L.S.)
