page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JONATHAN
TAYLOR, of Birmingham, in the County of Warwick, Iron Founder, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Tenth day of August, in the nineteenth year of his reign, did
give and grant unto me, the said Jonathan Taylor, His especial licence that I,
the said Jonathan Taylor, during the term of years therein expressed, should and
lawfully might use, exercise, and vend, within England, Wales, and Town of
Berwick-upon-Tweed, my Inventions of "CASTING OVAL-BELLIED CAST IRON POTTS,
AND NEALING, TURNING, TINNING, AND FINISHING THE SAME, AND ALSO NEALING,
TURNING, TINNING, AND FINISHING SUCH KIND OF ROUND CAST IRON POTTS AND
SAUCE PANS AS ARE MADE WITH A BEAD OR RIM ROUND THE Top ;". in which
said Letters Patent there is contained a provisoe obliging me, the said
Jonathan Taylor, under my hand and seal, to cause a particular description
of the nature of the said Invention, and which manner the same is to be
performed, to be inrolled in His Majestie's High Court of Chancery within
four calender months next and immediately after the date of the said recited

page_text: Letters Patent, as in and by the same, relation being thereunto had, will more
fully and at large appear.
NOW KNOW YE, that in compliance with the said provisoe, I, the said
Jonathan Taylor, do hereby declare my said Invention of Casting Oval-bellied
Cast Iron Potts, and of Nealing, Turning, Tinning, and Finishing the same,
and also Nealing, Turning, Tinning, and Finishing such Kind of Round Cast
Iron Pots and Sauce Pans as are made with a Bead or Rim round the Top,
is described in the following manner, that is to say :-
The pattern from which the oval-bellied cast iron pott is to be cast consists.
of brass or copper worked into the proper form of such a pot, and cut down the
middle into two parts. It is then moulded in sand inclosed in an iron box or
mould, which box or mould consists of four parts; that is, a top part, a bottom
part, and two middle parts; the two middle parts being made with great exact-
ness to slide on the bottom part, so as to move on and off without deviation,
with a quantity of small holes in the said two middle parts, to give vent to the
air which rushes out when the hot metal is poured in. The article is then
nealed by inclosing the same in a cast metal pan covered with coal dust or
ashes, so as to prevent the air getting to it as much as possible; which pan is
surrounded by fire till the pot becomes of a proper softness, which is generally
in about twenty-four hours. The turning of potts is performed by an oval
lathe made for that purpose upon a large construction and very strong, the pot
being fixed into a chock or hollow piece of wood to hold it while turning.
The tinning and finishing is performed by holding the pot to be tinned over
the fire till it becomes of a regular proper heat to receive the tin, when a
proper quantity of grain tin mixed with sal ammoniae is put into it, the pot
being still kept over the fire, and the tin worked about with sal ammoniac
till it takes and adheres to the pot in a proper manner. Round potts and
saucepans, with beads or rims round the tops, are nealed by the same
method as oval potts are. The turning of them is performed in a round
lathe, the articles being fixed in a chock as before mentioned. The beads
or rims round the tops are likewise turned by the same method, in order
to make them clear and bright, in a proper state to receive the tin; the
tinning and finishing is performed in the same manner as the oval pots, the
beads or rims round the tops being tinned at the same time and by the same
method as pots or saucepans are tinned.
In witness whereof, I, the said Jonathan Taylor, have hereunto put my
hand and seal, this Twentieth day of November, in the year of our
Lord One thousand seven hundred and seventy-nine.
JONATHAN TAYLOR. (L.S.)
