IMPROVEMENTS IN ROOFS AND OTHER PARTS OF BUILDINGS
Year: 1869

page_text: LETTERS PATENT to James Riley, of Shoreditch, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN ROOFS AND OTHER
PARTS OF BUILDINGS."
Sealed the 1st February 1870, and dated the 10th November 1869.
PROVISIONAL SPECIFICATION left by the said James Riley at the
Office of the Commissioners of Patents, with his Petition, on the
10th November 1869.
I, JAMES RILEY, of Shoreditch, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN ROOPS
AND OTHER PARTS OF BUILDINGS," to be as follows:-
My Invention consists in an improved method of constructing roofs.
and other parts of buildings of corrugated zinc or corrugated galvanized,
iron or other suitable metal, so that lightness both in weight and.
appearance will be combined with great strength and economy.
In one form of my improved roof the corrugated metal is fixed to angle.
irons placed at suitable distances apart by screwed hooks or other
suitable means, one end of which said hooks clips the angle iron, while

page_text: the other end passes through the space between the corrugations and is
secured therein by a nut or otherwise, and where a wooden purling is
used the metal is secured thereto by galvanized or other wood screws
passing through the part of a circle formed by the corrugations.
In forming a lining to an arch or bridge the angle iron to which the
corrugated metal is fixed as above stated is secured to the girders by
clips of any convenient form, or where no girders are used wedges are
driven into the brickwork and the clips secured thereto.
For a flat roof the zinc or galvanized iron or other metal is placed in
the form of slabs on the flat and secured thereto by clips only, no screws 1
or other means being used, so that the metal is free to expand or contract
according as it is acted upon by the temperature of the atmosphere or
other causes, the clips themselves being fixed by the wood roll having a
roll cap passing over it without being secured thereto.
My Invention is also applicable to the sides or walls of sheds and 1
other buildings as well as to roofs, and the corrugations may be either in
a concave or convex position, the metal in both cases being secured to
the supports in the same or in a similar manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Riley in the Great Seal Patent Office on
the 10th May 1870.
TO. ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
RILEY, of Shoreditch, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of November, 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 James Riley, Her special licence that I, the
said James Riley, my executors, administrators, and assigns, or such
others as I, the said James Riley, 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.

page_text: of Man, an Invention for "IMPROVEMENTS IN ROOFS AND OTHER PARTS OF
BUILDINGS," upon the condition (amongst others) that I, the said James
Riley, 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 James Riley, 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
following statement thereof, reference being had to the Figures on the
accompanying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say)
This Invention consists in improved modes of constructing roofs and
other parts of buildings of corrugated zinc or corrugated galvanized iron
or other suitable metal, so that lightness both in weight and appearance
will be combined with great strength, and thereby effect extreme economy
in material and labour.
In one form of my improved roof the corrugated metal is fixed by
screwed clips or hooks to angle irons placed at suitable distances apart,
one end of each clip clipping the angle iron and its other end passing
through the space between the corrugations and there secured by a nut,
and, when desired, instead of screwing the clips slots and keys may be
employed. Where a wooden purling is used the metal is secured thereto
by galvanized or other screws passing through the parts of the circles
forming the corrugations.
For forming a lining to an arch or bridge the sheets of corrugated
metal are fastened by screwed or keyed clips to angle irons fixed to the
girdlers by clips of any convenient form, and when no girders are used
wedges are driven into the brickwork or masonry and the clips secured
thereto.
In Figs. 1 and 2 representing different forms of corrugated roofs,
the nuts and washers at the screwed ends of the clips are marked a,
and in Figs. 3, 4, 5, 6, and 7, the clips are marked b; the angle
irons o, and the nuts and washers a, and one of the clips is shewn full
size in Fig. 8.

page_text: For a flat roof. the zinc or galvanized metal is placed in sheets on
the flat and secured thereto by clips only, no screws or other tightening
means being used, so that the metal is free to expand and contract when
acted upon by the temperature of the atmosphere or any other cause,
the clips themselves being fixed by the wood roll having a roll cap passing
over it without being secured thereto, and this description of roof is
shewn in part in Fig. 9.
This Invention is applicable to the sides or walls of sheds and other
buildings as well as to roofs, and the corrugations may be either in a
concave or convex position, the metal in both cases being secured to the
supports in the same or similar manner.
Having now described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that I claim the improved modes of constructing roofs and
other parts of buildings as herein described and illustrated in the
accompanying Sheet of Drawings.
In witness whercof, I, the said James Riley, have hereunto.sct
my hand and seal, this Ninth day of May One thousand eight
hundred and seventy.
