IMPROVEMENTS IN ROLLS FOR CONNECTING SHEETS OF ZINC AND OTHER METALS.
Year: 1865

page_text: LETTERS PATENT to Rowland George Fisher, of No. 17, Great George
Street, Westminster, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN ROLLS FOR CONNECTING SHEETS OF ZINC AND OTHER METALS.
PROVISIONAL SPECIFICATION left by the said Rowland George Fisher
at the Office of the Commissioners of Patents, with his Petition, on the.
9th March 1865.
I, ROWLAND GEORGE FISHER, of No. 17, Great George Street, Westminster,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN ROLLS FOR CONNECTING SHEETS OF ZINC AND
OTHER METALS EMPLOYED FOR COVERING ROOFS AND OTHER ENCLOSURES," to be as:
follows:-
My Invention has reference to the mode of connecting the sheets of zinc
and other metals employed for covering roofs and side or other enclosures by
means of wood "rolls." I form such "rolls" with an overhanging shoulder on
either side, and with grooves on the under surfaces of the shoulders. I then
cover the roll with zinc or other sheet metal by "drawing" the metal upon the
roll, the metal being made to lap round the before-mentioned shoulders. The
edges of the sheets of zinc or other metal on either side of the roll are turned
up so as to fit in the before-mentioned grooves, being by this means securely
held by the roll. The separate lengths of sheet metal that are drawn upon
#

page_text: the roll are not joined to each other, but where two ends meet they are each
secured to the roll by means of a screw or nail passing through holes in the
metal formed slotted to allow for expansion and contraction. This butt joint
of the metal covering, as also the screws or nails securing the same, are then
covered by a cap having the same form as the roll, and having an astragal or
small hollow moulding formed at each end, which cap is fixed to the roll by being
soldered to one of the lengths of metal only so as to allow of the two lengths
expanding and contracting freely. The astragals at each end of the cap
serve both to prevent the wet from passing underneath it through capillary
attraction and to strengthen and impart a finished appearance to the cap.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Rowland George Fisher in the Great Seal Patent Office
on the 9th September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROWLAND
GEORGE FISHER, of No. 17 Great George Street, Westminster, in the County
of Middlesex, send greeting.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Rowland George Fisher, Her special licence that I, the said
Rowland George Fisher, my executors, administrators, and assigns, or
such others as I, the said Rowland George Fisher, my executors, admi-
nistrators, 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 ROLLS FOR CONNECTING
SHEETS OF ZINC AND OTHER METALS EMPLOYED FOR COVERING ROOFS AND OTHER
ENCLOSURES," upon the condition (amongst others) that I, the said Rowland
George Fisher, 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.

page_text: NOW KNOW YE, that I, the said Rowland George Fisher, 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 accompanying Draw-
ing, and to the figures and letters marked thereon, that is to say:-
My Invention has reference to the mode of connecting the sheets of zinc and
other metals employed for covering roofs and side or other enclosures by
means of wood "rolls." I form such rolls with an overhanging shoulder. on
either side and with grooves on the under surfaces of the shoulders; I then cover
the roll with zinc or other sheet metal by "drawing" the metal upon the
roll, the metal being made to lap round the before-mentioned shoulders. The
edges of the sheets of zinc or other metal on either side of the roll are turned
up so as to fit in the before-mentioned grooves, being by this means securely
held by the roll. The separate lengths of sheet metal that are drawn upon
the roll are not joined to each other, but when two ends meet they are each
secured to the roll by means of a screw or nail passing through holes in the
metal formed slotted to allow for expansion and contraction. This butt joint
of the metal covering, as also the screws or nails, securing the same, are then
covered by a cap having the same form as the roll, and having an astragal or
small hollow moulding formed at each end, which cap is fixed to the roll by
being soldered to one of the lengths of metal only so as to allow of the two
lengths expanding and contracting freely. The astragals at each end of the
cap serve both to prevent the wet from passing underneath it through capillary
attraction and to strengthen and impart a finished appearance to the cap.
These caps may also be made ornamental by embossing the surface.
On the accompanying Drawing is shown the construction of my improved
roll and cap.
Figure 1 shows a transverse section through the roll; Figure 2 shows a
part longitudinal section; and Figure 3 shows a side elevation.
The roll A is formed with two projecting shoulders a, a, in the under
surfaces of which grooves b, b, are formed, into which fit the turned-up ends
of the sheet metal B, B, to be connected. The roll A is covered with sheet
metal C, which is by preference "drawn" upon the roll, being made to lap round
the under surface of the shoulders a, a, whereby it is securely held upon the
roll. The ends of each length of such metal covering are secured by means
of screws D, D, fitting in slotted holes in the metal so as to allow of the
expanding and contracting of the same. For this purpose also a small space
is left between the adjoining ends of two lengths as shown, and such joint
between two lengths is then covered by means of the cap E, which is soldered
--

page_text: to the one-length but not to the other in order to allow of the free expansion
and contraction of the two lengths of metal. At each end of the cap E is
formed a hollow astragal moulding e, e, in order both to impart a finished
appearance thereto and to prevent water from penetrating beneath the cap, as
any water that may pass into the hollow space under the moulding will run
down the sides of the roll on to the plates B, for which purpose also the
mouldings e are made to project rather lower than the rest of the cap.
Having now described the nature of my Invention, and in what manner the
same is to be performed, I wish it to be understood that what I claim under
the herein-before in part recited Letters Patent is,―
First, covering rolls with sheet metal by "drawing" the metal upon the rolls.
Second, constructing rolls having projecting shoulders and grooves into
which the ends of the sheet metal fit, and covered with sheet metal made to
lap round the under surfaces of the said shoulders, substantially as herein-
before described.
Third, the employment of a cap for covering the joint of two lengths of
sheet metal upon the roll, which cap is fixed at one end only to the sheet metal,
and has at the other end or at both ends a hollow moulding, substantially as
herein-before described.
In witness whereof, I, the said Rowland George Fisher, have hereunto
set my hand and seal, this Ninth day of September, in the year of
our Lord One thousand eight hundred and sixty-five.
ROWLAND GEORGE FISHER.
