Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
NORTH, of Stangate, in the County of Surrey, Slater, 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 Fourteenth day of November, in the eighth year of Her reign; did,
for Herself, Her heirs and successors, give and grant unto me, the said William
North, Her especial-licence, full power, sole privilege and authority, that. I,
the said William North; my exors, admors, and assigns, or such others as I,
the said William North, my exors, adñiors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the. terni
of years therein expressed; should and lawfully might make,..use, exercise,
and vend; within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN COVERING ROOPS AND FLATS WITH SLATE;" in
which said Letters Patent is contained a proviso that I, the said William North.
shall cause a particular description of the nature of my said Invention, 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 imme-
diately after the date of the said in part recited Letters Patent, as in and

page_text: by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with. the said proviso, I, the said
William North, 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) :-
My Invention consists of a mode of using battens of wood in combination
with slate covers of roofs and flats of buildings, whereby the slabs of slate
used in covering roofs and flats of buildings are not fixed to the rafters or
joists, thus preventing the joints of the slate becoming defective from the
warping or vibration of such covered roofs or flats.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed,
in the various Figures of which the same letters are used to indicate similar
parts.
DESCRIPTION OF THE DRAWING.
Figure 1 is part of a roof or flat of a building covered with slate according
to my Invention; Figure 2 is a section thereof, taken in the direction of
the length of the rafter or joist; Figure 3 is an under side view; Figure 4 is
a transverse section thereof. a, a, are the rafters or joists; b, b, are the wood
.battens which are received into notches or recesses formed in the rafters or
joists as shewn; c, c, are short laths or battens of wood between the battens
b, b. These battens b and c receive the ends and sides of the slabs of slate
d, d, for covering roofs or flats. And it will be seen that the under side edges
of the slabs are cut away so as to leave a channel for more effectually bedding
the slabs in putty; e, e, are screws which combine the slabs to the laths or
.battens b and c, by which it will be seen that the whole covering of slate is
bound and fixed together without being fixed to the rafters or joists.
Having thus described my Invention, I would wish it to be understood that
what I claim is the mode of combining the use of wood battens with slate
covering for roofs and flats, as herein described.
In witness whereof, I, the said William North, have hereunto set my hand
and seal, this Thirteenth day of May, in the year of our Lord. One
thousand eight hundred and forty-five.
WILLIAM
(L.S.) NORTH.
