A NEW OR IMPROVED MANUFACTURE OF METALLIC TILES OR SLATES FOR ROOFING
Year: 1869

page_text: LETTERS PATENT to Charles Denton Abel, of No. 20, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Patent
Agent, for the Invention of "A NEW OR IMPROVED MANUFACTURE OF
METALLIC TILES OR SLATES FOR ROOFING."-A communication from
abroad by Alfred Camille de la Marteliére, of No. 21, Rre Beranger,
Paris, France, Manufacturer.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd October 1869.
I, CHARLES DENTON ABEL, of No. 20, Southampton Buildings,.
5 Chancery Lane, in the County of Middlesex, Patent Agent, do hereby
declare the nature of the said Invention for "A NEW OR IMPROVED MANU-
FACTURE OF METALLIC TILES OR SLATES FOR ROOFING," to be as follows:-
This Invention consists in the manufacture of roofing tiles or slates of
galvanized sheet iron corrugated to impart stiffness and strength thereto..

page_text: For this purpose the sheet iron is rolled or stamped for producing the
requisite longitudinal corrugations or ribs thereon, after which it is cut
up into lengths corresponding with the size of ordinary tiles or slates,
and these are then galvanized. These metallic tiles are by preference
formed with two lateral corrugations or ribs of greater height than the
intermediate ones, by means of which they are made to overlap the
corresponding corrugations of the adjoining tiles, and thus to form more
perfect joints than ordinary tiles or slates, in addition to which they have
the further advantages of being readily adapted in size to suit any
structure and require no skilled labour for fixing them. They are
furthermore lighter and less expensive than ordinary tiles or slates, and
require considerably less repairs than these, and they may be removed
with great ease.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Denton Abel in the Great Scal Patent
Office on the 21st April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
DENTON ABEL, of No. 20, Southampton Buildings, Chancery Lane, in
the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of October, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Denton Abel, Her special licence
that I, the said Charles Denton Abel, my executors, administrators,
and assigns, or such others as I, the said Charles Denton Abel, 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 "A NEW OR IMPROVED
MANUFACTURE OF METALLIC TILES OR SLATES FOR ROOFING," a communication
to me from abroad by Alfred Camille de la Martelière, of No. 21, Rue
Beranger, Paris, France, Manufacturer, upon the condition (amongst
others) that I, the said Charles Denton Abel, my executors or adminis-

page_text: 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 per-
formed, 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 Charles Denton Abel, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the accom-
panying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say: -
This Invention consists in the manufacture of roofing tiles or slates of
galvanized sheet iron corrugated to impart stiffness and strength thereto.
For this purpose the sheet iron is rolled or stamped for producing the
requisite longitudinal corrugations or ribs thereon, after which it is cut
up into lengths corresponding with the size of ordinary tiles.or slates,
and these are then galvanized. These metallic tiles are by preference
formed with two lateral corrugations or ribs of greater height than the
intermediate ones, by means of which they are made to overlap the corre-
sponding corrugations of the adjoining tiles, and thus to form more
perfect joints than ordinary tiles or slates, in addition to which they have
the further advantages of being readily adapted in size to suit any
structure, and require no skilled labour nor special apprentisage for
fixing them, as they are fixed in precisely the same manner as ordinary
tiles or slates and upon any ordinary roof covering as prepared for these.
They are furthermore lighter and less expensive than ordinary tiles or
slates and require considerably less repairs than these, and they may
be removed with great ease and at a trifling cost, as also without damage
to the tiles.
On the accompanying Drawing is shewn the before described improved
construction of roofing tiles.
Figure 1 shews a plan of one of the metallic tiles, and Figure 2 shews
an end view of the same. The tile A is of galvanized sheet iron; it has
formed upon it, either by rolling or stamping, the deep lateral longi-
tudinal corrugations b, b, and the shallower intermediate corrugations
c, c. The latter serve to impart rigidity to the metal, while the lateral

page_text: corrugations insure the perfect super-position of the tiles over cach
other.
Figures 3 and 4 shew respectively a plan and an end view of three such
galvanized iron tiles A, A1, A2, placed in position; they are nailed to
the roofing boards, rafters, or purlins in precisely the same manner as
ordinary tiles or slates, requiring therefore no special apprentisage of
the workmen.
Having thus described the nature of this Invention, and in what
manner it is to be performed, as communicated to me by my foreign
correspondent, I wish it to be understood that I do not limit myself to
the precise configuration of the tiles as shewn on the accompanying
Drawing, as this as also the number and form of the corrugations may
be variously modified to suit different circumstances under which they
are applied; but what I claim is, the construction and application of
galvanized sheet iron roofing tiles provided with longitudinal corrugations
or ribs, substantially as herein-before set forth.
In witness whereof, I, the said Charles Denton Abel, have here-
unto set my hand and scal, this Twentieth day of April, in
the year of our Lord One thousand eight hundred and seventy.
