TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GRIFFITII
JONES, of Bangor Wharf, Pimlico, in the Parish of St. George's, Hanover

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of August, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Griffith Jones, Her special licence that I, the said Griffith Jones,
my executors, administrators, and assigns, or such others as 1, the said
Griffith Jones, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "SECURING JOINTS
IN SLATE RIDGE ROLL," upon the condition (amongst others) that 1, the said
Griffith Jones, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Griffith Jones, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the follow-
ing statement-
My Invention is intended to strengthen and improve the joints of slate
ridge roll. For the above purpose I fasten under the flange at the joint of
ridge a piece of metal or other suitable material in a separate piece under one
flange, or in a piece of sufficient length to cross the breadth of the two flanges
and connect them together; but in either case the piece of metal or other
material must be of sufficient breadth to lap under the joint, so as to support
the end of the flange next contiguous.
Upon the upper angle of the ridge above mentioned is laid a roll, the ends
of which I connect together by inserting (in a slot) a tongue of metal or other

page_text: suitable material laid in oil cement. The ends of the said roll I prefer being
so arranged as to break joint with or overlap the joint in the ridge.
In order to explain my said Invention more fully, I now proceed to describe
the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a portion of the ridge as it would appear in perspective, and
Figure 2 is an end view of the same. a is the roll; b, the tongue set in
cement; c, the flanges forming the ridge; and d, the piece of metal fastened
under the joint by means of the rivets c, or in any convenient manner.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is the
mode herein described of securing the joints of slate ridge roll.
In witness whereof, I, the said Griffith Jones, have hereunto set my
hand and seal, this Twenty-eighth day of February, in the year of
our Lord One thousand eight hundred and fifty-nine.
GRIFFITH JONES. (L.S.)
