CARTER, of Delabole, in the County of Cornwall, Slate Merchant, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-seventh day of September, in the eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Carter, Her especial licence, full power, sole privilege and authority,
that I, the said James Carter, my exors, adññors, and assigns, or such others
as I, the said James Carter, my exors, adññors, 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 in the Islands of Jersey, Guernsey, Alderney, Sark, and Man, and
also in all Her said Majesty's Colonies and Plantations abroad, my Invention
of "IMPROVEMENTS IN CUTTING SLATE FOR ROOFING AND OTHER PURPOSES;" in
which said Letters Patent is contained a proviso that I, the said James
Carter, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
James Carter, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):
DESCRIPTION OF THE DRAWING,
My Invention consists of a steel cutter A attached to the outer end of the
arm of a wheel B revolving vertically. The face of the cutter A is brought off
six inches from the wheel B to allow room for the irregularities of the slate in
an uncut state. The rest C, on which the slate is to be cut, is placed level in
a line of the axis of the wheel B, and detached from it, so that the face of the
cutter A in revolving passes the face of the rest C at one sixteenth of an inch
distance. The line of the edge of the cutter A is fixed to the wheel B to
meet the slate at an angle of about eight degrees. A guide D is brought from
the outer end of the rest C at right angles with the face of the cutter A, and
on the guide is marked a scale of inches, commencing from the face of the
cutter.
What I claim is, the mode of cutting roofing slate with the edges perfectly
straight, and at right angles with each other; also that I avoid the shelling off
of the under side of large portions of the slate, which is unavoidable in the old
process of cutting by hand, and consequently producing a uniformity and
beauty of appearance when on the roof not hitherto obtained.
In witness whereof, I, the said James Carter, have hereunto set my hand
and seal, this Twenty-fifth day of March, in the year of our Lord
One thousand eight hundred and forty-five
Enrolled the Twenty-seventh day of March, in the year of our Lord
One thousand eight hundred and forty-five.
