JACOB the younger, of Saint Mary Ax, in the City of London, Coachmaker,
send greeting.
WHEREAS I, the said Joseph Jacob the younger, did, by my Petition,
humbly represent to His present most Excellent Majesty King George the
Third, that I had, with much application and expence, invented "A METHOD
FOR THE BETTER CONSTRUCTION OF WHEEL CARRIAGES, BY THE APPLICATION OF
UNITED SPIRAL SPRINGS, HOOP WHEELS, AND LEATHER BOXES," which I appre-
hended would be of great utility to the publick, and that I was the first and only
Inventor of the said spiral springs, hoop wheels, and leather boxes; I there-
fore most humbly prayed His said Majesty to grant unto me, my executors,
administrators, and assigns, His Royal Letters Patent for the sole benefit
and advantage of my said Invention within that part of His said Majesty's
Kingdom of Great Britain called England, His Dominion of Wales, and Town
of Berwick-upon-Tweed, for the term of fourteen years, according to the
Statute in that case made and provided; His said Majesty, being willing to
give encouragement to all arts and inventions which might be for the publick
good, was graciously pleased to condescend to my request, and therefore, by
His Royal Letters Patent, bearing date at Westminster, the Thirteenth day
of July, in the ninth year of His reign, of His especial grace, certain know-
ledge, and meer motion, for Himself, His heirs and successors, did give and
grant unto me, the said Joseph Jacob the younger, my executors, adminis-
trators, and assigns, His especial licence, full power, sole priviledge and autho-
rity, that I, the said Joseph Jacob the younger, my executors, administrators,

Jacob the younger, my executors, administrators, or assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend my said Invention within that said part of His Majesty's
said Kingdom of Great Britain called England, His Dominion of Wales, and
Town of Berwick-upon-Tweed, in such manner as to me, the said Joseph Jacob
the younger, my executors, administrators, and assigns, or any of us, should in
our discretions seem meet, and that I, the said Joseph Jacob the younger, my
executors, administrators, and assigns, should and lawfully might have and
enjoy the whole profit, benefit, commodity, and advantage from time to time
coming, growing, accrewing, and arising by reason of the said Invention, for
and during the term of years therein mentioned, to have, hold, exercise, and
enjoy the said licence, powers, priviledges, and advantages therein-before
granted or mentioned to be granted unto me, the said Joseph Jacob the
younger, my executors, administrators, and assigns, for and during and unto
the full end and term of fourteen years from the date of the said Letters
Patent next and immediately ensuing, and fully to be compleat and ended,
according to the Statute in such case made and provided; in which said Letters
Patent is contained a proviso that if I, the said Joseph Jacob the younger,
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 four calendar months next and
immediately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby granted,
should utterly cease, determine, and become void, anything therein-before con-
tained to the contrary thereof in anywise notwithstanding, as in and by the
said Letters Patent (relation being thereunto had) may more fully and at large
appear.
NOW KNOW YE, that I, the said Joseph Jacob the younger, in compliance
with the said proviso, do hereby describe and ascertain the nature of my afore-
said Invention, and declare that the Plan thereof drawn in the margin of
these Presents is composed of the following particulars (that is to say):-
A, A, are two spiral springs united together by the bar B. C, C, are two
forked socketts, into which the barr B is fixed at bottom, and fastened to the
spring plates at top. D, D, are two double stays, with eyes in the tops to
receive the barr B. E, E, are two shackles, fastened to the eye of the spring

page_text: plates, to receive the braces which the body of the coach hangs by. At the
ends of the barr B are two nutts or pins to confine the springs, when the power
is applied to the shackles E, E; the springs and barr are uniformly wound
upon the centers at the tops of the double stays D, D. The hoop wheels
differ from those now in use in the felleys or periphery, which, instead of being
sawed out of timber to the shape required, are made of strait-grained wood,
of any width, in one, two, or more picces, and bent by art like a hoop to the
necessary form. The leather box is made, either long or short, of a piece of
strong leather closed and sewed together, along the outside of which is either
one or two esses or ridges for fastning the box into the nave of the wheel.
In witness whereof, I, the said Joseph Jacob the younger, have hereunto
set my hand and seal, this Twelfth day of October, in the year of our
Lord One thousand seven hundred and sixty-nine, and in the ninth
year of the reign of our said Sovereign Lord George the Third, by
the grace of God of Great Britain, France, and Ireland King, Defender
of the Faith, and so forth.
Sealed and delivered (being first duly
stampt) in the presence of
BIGOE HENZELL.
