page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, COLIN
MACKENZIE, of Oxford Market, in the Parish of Saint Mary-le-bone, in the
County of Middlesex, Whitesmith, send greeting.
WHEREAS His most Sacred Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Thirteenth day of August, in the thirty-first year of His reign, did
give and grant unto me, the said Colin Mackenzie, my exors, admors, and
assigns, special licence, full power, sole priviledge and authority, to me, the
said Colin Mackenzie, my exors, admors, and assigns, during the term of
fourteen years from the date of the said Letters Patent, to make, use, exercise,
and vend, within England and Wales and the Town of Berwick-upon-Tweed,
my "NEW INVENTED LINK FOR A CHAIN, AND A CERTAIN WAY AND METHOD OF
MAKING A CHAIN OF SUCH LINKS, BY UNITING THE SAME; AND WHICH MAY DE
USED AS A MOORING CHAIN, SHIP CABLE, WATCH CHAIN, OR FOR ANY OTHER PURPOSE
WHERE A CHAIN CAN BE USED, AND WHICH CAN BE LENGTHENED OR SHORTENED AT
PLEASURE BY ADDING OR TAKING AWAY SUCH LINKS WITHOUT CUTTING OR BREAKING
ANY ONE OR MORE OF THEM;" in which said Letters Patent there is contained a
proviso that if I, the said Colin Mackenzie, should 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 inrolled in His said Majesty's High Court of Chancery
within one calendar month next and immediately after the date of the said

page_text: Letters Patent, that then the said Letters Patent and all liberties and
advantages whatsoever thereby granted should cease, determine, and become
void, as in and by the said Letters Patent, relation being thereunto had, may
more fully appear.
NOW KNOW YE, that I, the said Colin Mackenzie (in compliance with
and in pursuance of the said proviso in the said in part recited Letters Patent
contained) by this Instrument in writing, under my hand and seal, do par-
ticularly describe and ascertain the nature of my said Invention in the said
Letters Patent mentioned, and in what manner the same is to be performed.
and declare the same to be in manner and form following (that is to say) :-
I take a piece of steel, iron, or any other metal, or leather, hemp, horsehair,
or any other elastic substance, according to the use or purpose my link is to be
applied to or adapted for, the piece to be twelve inches long and one inch
thick, or any other length and thickness, according to the use and purpose of
the link; I make an eye or hole in each end of the piece, or instead of making
an eye or hole I bend the ends, or fix a pin, stub, or hook in the ends or any
convenient fastnings, as best answers the intention of the link; then I bend
my piece into an oval shape or such other shape or form as will best answer the
use or purpose for which my link is to be applied to or adapted for, keeping the
ends apart or distant from each other, according to the degree of spring I want
my link to give, or I cast in a mould the above link of iron, brass, copper, or
any other metal. To unite my links for making chains, I take one link and
place a second link in the eyes or holes in the end of the first link,
then I take a third link and place it in the eyes or holes in the
ends of the second link, and so continue adding link after link until a chain
is formed, or long enough for the purpose it is intended; and to shorten
such chain, I disunite the said links by taking or pulling out one link out of
the eyes or holes in the ends of the next link, and so continue taking or
pulling out one link after another until my chain is as short as I wish it, or
reduced to one link. If I want my chain not to spring I bend the ends of
my link close together; and when my link is to be applied for ship cables or
coaches, or other carriages, I unite my steel, iron, or other metal link to my
link or links made of leather, hemp, hair, or any other such elastic substance,
to prevent the disagreeable noise and rattling of metal links. The leather,
hemp, or hair link to be made of such elastic substance, I bind with three or
more hoops or bands, according to the number of the metal links used. I
place my metal link in the double or middle fold of the leather link. I then
unite them in the middle with one hoop or band, and I unite one end, or I
unite each end of my metal link into the leather link by one or more pins or

page_text: stubs fixed in my metal links, or with a band or hoop. I likewise unite the
leather link near or close at one end, or at both ends of my metal link, with a
hoop or band, for keeping the pressure on the metal link in an angular
direction, which thereby gives the degree of spring required. Chains may be
made of the links made and fashioned as above mentioned and described for
mooring chains, ship cables, coaches and other carriages, cranes, pullies,
watches, hanging of lanthorns, or any other purpose where a chain can be
used, and more particnlarly for hanging bodies on an elastic balance.
In witness whereof, I, the said Colin Mackenzie, have hereunto set my
hand and seal, the Twelfth day of September, in the year of our Lord
One thousand seven hundred and ninety-one.
