CERTAIN IM- PROVEMENTS IN MACHINES FOR PLOUGHING LAND, CALLED DOUBLE-FURROW AND SINGLE-FURROW PLOUGHS
Year: 1802

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SOUTHEY Lord SOMERVILLE, of Hill Street, Berkeley Square, in the County of
Middlesex, send greeting.
WHEREAS His present Majesty King George the Third, by His Letters
Patent, bearing date at Westminster the Sixth day of February, in the .forty-
second year of His reign, hath given and granted unto me, the said John
Southey Lord Somerville, my executors, administrators, and assigns, special
license, full power, sole privilege and authority, during the term of years
therein expressed, to make, use, exercise, and vend, within that part of His
said Majesty's Kingdom of Great Britain called England, His Dominion of
Wales, and Town of Berwick-upon-Tweed, my Invention of "CERTAIN IM-
PROVEMENTS IN MACHINES FOR PLOUGHING LAND, CALLED DOUBLE-FURROW AND
SINGLE-FURROW PLOUGHS;" in which said Letters Patent is contained a proviso
obliging me, the said John Southey Lord Somerville, particularly to describe
and ascertain the nature of my said Invention, and in what. manner the same
is to be performed, under my hand and seal, and cause the same to be in-
rolled in His Majesty's High Court of Chancery within one calendar month
next after the date of the said Letters Patent, as in and by the same,
reference being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Southey Lord Somerville, do hereby describe and ascertain the nature
of my said Invention or improvement and addition to the said plough, as well
by the plates or delineations of the said machine in the margin of these
Presents, as the description or explanation set forth (that is to say) :-

page_text: Moveable cast-iron mould plates a, a; the new coulters b, b; the line
below which the workt-irou mould plate should be of double thickness; c, c,
stays to coulter d, d. The moveable mould plates a, a, will, by a screw or
ketch, be made to extend at will some inches from the mould board, and will
lay the furrow more or less flat, so as best to suit the different purposes of
working land. This principle must be indispensibly necessary to two-furrow
ploughs, because any attempt to produce the same effect by hand would throw
one (the land one) out of work; and bury the other too deep. There is good
authority to add that the moveable plate will be essentially serviceable also in
every single-furrow plough. The double-edge coulters .b, b, being equally
strong, but far more narrow, present so much less for resistance in work, and
are less likely therefore to be deranged, in the remedy of which arrangement
much time is lost.
In witness whereof, I, the said John Southey Lord Somerville, have
hereunto set my hand and seal, the Sixteenth day of February, in the
year of our Lord One thousand eight hundred and two.
Sealed and delivered, by the within-
named John Southey Lord Somer-
ville, being first duly stampt, in the
SOMERVILLE. (L.S.)
AND BE IT REMEMBERED, that on the Seventeenth day of February,
the year above mentioned, the aforesaid John Southey Lord Somerville
caine before our Lord the King in His Chancery, and acknowledged the
Specification aforesaid, and all and every thing therein contained, in. form
above written. And also the Specification aforesaid was stamped according to
the tenor of the Statute in that case made and provided.
Inrolled the Eighteenth day of February, in the year above written..
