TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
RIDSDALE, of the Minories, in the City of London, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Ridsdale, Her special licence, that I, the said Joseph Ridsdale,
my executors, administrators, and assigns, or such others as I, the said Joseph
Ridsdale, 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 "IMPROVEMENTS IN PREPARING SHEET
LEAD FOR COVERING FLOORS, STAIRS, AND OTHER LIKE PURPOSES," upon the condition
(amongst others) that I, the said Joseph Ridsdale, my executors or adminis-
trators, 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 Joseph Ridsdale, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed, that
is to say :-
My Invention consists in sinking by pressure from presses, rolls, or hand
tools, designs or patterns in that surface of the sheet lead which when laid
is to come uppermost, and in filling up such sunken designs or patterns
with color or not, according to requirement.
When I use rolls I cause the sunken parts of the pattern to be in
relief upon one of the rolls, say the upper roll, while the bottom roll is smooth
on its surface. If for instance, the pattern is such as shewn in the accom-3
panying Drawing, which is a plan of the lead covering, the parts colored red
are sunk by corresponding dies in relief on the roll. Where presses or hand

page_text: tools are used the dies are formed in relief to produce the sunken parts of
the pattern in the lead covering.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, preparing sheet
lead for covering floors, stairs, and other like purposes, in manner herein-
before described.
In witness whereof, I, the said Joseph Ridsdale, have hereunto set my
hand and seal this Fifteenth day of July, in the year of our Lord One
thousand eight hundred and sixty-two.
JOSEPH RIDSDALE. (L.s.)
