Year: 1832

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
CRAWHALL, of the Town and County of Newcastle-upon-Tyne, Rope Maker,
.send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Eighth day of August, in the third year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Joseph Crawhall, my exors," admors, and assigns, His special licence that
I, the said Joseph Crawhall, my exors, adññors, and assigns, or such others
as I; the said Joseph Crawhall, my exors, adiñiors, or assigns, should at any
time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, and also in all: His, said Majesty's Colonies and Plantations abroad,
my Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF FLAT ROPE, SUCH
AS IS USED IN MINES;" in which said Letters Patent is contained a proviso,
obliging me,' the said Joseph Crawhall, by an instrument in writing under
my hand and seal, particularly to describe and ascertain the 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 said Majesty's High Court of Chancery
within two calendar months next and immediately after the date of the
said recited Letters Patent, as in and by the same, reference being thereunto
bad, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Crawhall, do hereby declare the nature of my said Invention to con-
sist in forming flat ropes of ropes all of which have been laid or made at one
and the same operation and by one connected machine, so as to insure that
similarity and equality of form, size, twist, and tension in each so essential to
the excellence of a rope, and which cannot be obtained by the union of ropes
laid or made by different operations and at different times, as now practised;
and in further compliance with the said proviso,' I, the said Joseph Crawhall,
do hereby describe the manner in which my said Invention is to be performed
by the following description thereof, reference being had to the Drawing
annexed, and to the letters marked thereon, that is to say:-
DESCRIPTION OF THE DRAWING.
This Drawing represents a perspective view of the machine for laying rope.
Now whereas the ordinary machines for this purpose only extend to the
laying of two repes at a time, and as flat ropes are formed by the lateral union
of two, four, or more ropes, it is necessary to provide the means of laying any
number of ropes required to form a flat rope at the same operation and in one
machine. For this purpose I add to the rope-laying machinery which is
calculated to lay two ropes only as many of the wheels marked A and S,
together with their accompanying apparatus, as are necessary to lay the whole
number of ropes required for the flat rope, whatever that number may be.
The parts coloured blue in this Drawing are those added to the machine for
the purpose of making ropes sufficient for a flat rope of four ropes in width,
which ropes, when so made at one and the same operation, as aforesaid, and
lateraly united in the usual way, form a flat rope of my improved make fit
to be used in mines.
Now whereas I claim as my Invention the making of flat ropes of such
ropes only as have been all laid as nearly as possible of one and the same
size, also laid at one and the same time, by one and the same operation, and
by one connected piece of machinery, the usual precaution of twisting what
is called right and left being attended to, and stitched together in the ordinary
manner, whereby I am enabled to prevent any unequal stretching, tension,
or wear of the flat rope when brought into use; and such my Invention being,
to the best of my knowledge and belief, entirely new and never before used
within that part of His said Majesty's United Kingdom of Great Britain and
Ireland called England, His said Dominion of Wales or Town of Berwick-
upon-Tweed, nor in any of His said Majesty's Colonies or Plantations abroad,
I do hereby declare this to be my Specification of the same, and that I do

page_text: verily believe this my said Specification doth comply in all respects fully and
without reserve or disguise with the proviso in the said herein-before in part
recited Letters Patent contained, wherefore I do hereby claim to maintain
exclusive right and privilege to my said Invention.
