· Improvements in or connected with Metallic Roofing.
I, CHARLES FREDRICK ELLIOTT, of 1 Wellington Fields, Smithdown Road,
Liverpool, in the County of Lancaster, Engineer, do hereby declare the nature of
this invention to be as follows:-
My invention has reference to roofs wherein the outer surface is covered with
and consists of ductile metal such as zinc, wrought iron and steel, copper, brass, or
the like, and has for its object amongst other things to provide a simple means or
mode of fastening the capping or ridge pieces used in the kind of roofing referred
to and at the same time which shall afford. complete freedom for expansion and
contraction of the sheets or plates and parts.
I will, for the sake of simplicity and clearness of description, describe the nature
of my invention in its application to the covering of wooden (or other) roofs zinc or
its equivalent being the metal used, and wherein the roof is divided into strips
or divisions with interspaced dividing strips, at which the edges of the adjacent
plates abut and are connected and held in position by capping fitting over same.
The plates are turned up at the edges, and the turned up parts lie against the
sides of the dividing strips, whilst the capping is fastened in position by bands or
strips of metal bent and formed as hereinafter described, said bands or strips
themselves being fastened to the roof by the dividing strips, under which they are
passed, and are suitably secured thereto or to the wooden planking.
The capping consists of inverted trough or gutter shaped lengths of metal-
preferably with slightly inturned edges which bear against the upturned edges of
the sheets or plates.
In constructing a roof and applying the metal, the fastening strips are secured as
described, and the plates are placed in position, the strips standing upright with
their ends upwards and one being longer than the other. The strips on each side
are then turned down against the upturned edges of the plates and outwards, and
the capping is placed in position over the plate edges and fastening strips. Then
one side of the strips is turned upwards against the side of the capping, and
outwards at the level of the top of the capping, whilst the other part (the longer
one) is also turned upwards in the same manner, and inwards towards the other
part of the strip over the top of the capping lying above this part of the strip,
with its edge projecting beyond the edge of the shorter part. The projecting
edge is then turned down and under the edge of the other part, and so fastened
thereto, and both are bent or knocked down closely against the part of the shorter
strip bearing against the outer surface of the capping, and the fastening is complete.
In this last operation the strips are firmly drawn or brought into contact with the
capping and so press it down into position and binds it there.
The above example of my invention explains one mode of its application, but it
is not strictly confined to the particular forms of parts, or mode of operation
specified, as these may be varied without departing from its essential characteristics;
and it may be applied to roofs which differ as to the particular forms of parts
specified or material used.

I, CHARLES FREDRICK ELLIOTT, of 1, Wellington Fields, Smithdown Road,
Liverpool, in the County of Lancaster, Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has reference to roofs wherein the outer surface is covered with
and consists of double metal such as zinc, wrought iron and steel, copper, brass, or
the like, and has for its object amongst other things to provide a simple means or
mode of fastening the capping or ridge pieces used in the kind of roofing referred
to, and which at the same time shall be perfectly "weather tight" and shall
afford complete freedom for expansion and contraction of the sheets or plates and
parts.
I will for the sake of simplicity and clearness of description, describe the nature
of my invention in its application to the covering of wooden (or other) roofs, zinc
or its equivalent being the metal used, and wherein the roof is divided into strips
or divisions with interspaced dividing strips, at which the edges of the adjacent
plates abut and are connected and held in position by capping fitting over same.
The plates are turned up at the edges; and the turned up plates lie against the
side of the dividing strips or rolls, whilst the capping is fastened in position by
bands or strips of metal bent and formed as hereinafter described, said bands or
strips themselves being fastened to the roof by the dividing strips or rolls, under
which they are passed, and are suitably secured thereto or to the wooden
planking.
The capping consists of inverted trough or gutter shaped lengths of metal-
preferably with slightly inturned edges, which bear against the upturned edges of
the sheets or plates.
In constructing a roof and applying the metal, the fastening strips are secured as
described, and the plates are placed in position, the strips standing upright with
their ends upwards and one being longer than the other. The strips on each side
are then turned down against the upturned edges of the plates and outwards, and
the capping is placed in position over the plate edges and fastening strips. Then
one side of the strips is turned upwards against the side of the capping, and
outwards at the level of the top of the capping, whilst the other part (the longer
one) is also turned upwards in the same manner, and inwards towards the other
part of the strip over the top of the capping lying above this part of the strip,
with its edge projecting beyond the edge of the shorter part. The projecting edge
is then turned down and under the edge of the other part, and so fastened thereto,
and both are bent or knocked down closely against the part of the shorter strip
bearing against the outer surface of the capping, and the fastening is complete.
In this last operation the strips are firmly drawn or brought into contact with the
capping and so press it down into position and binds it there.
The drawings hereto annexed illustrate the invention above described, the views
hewn being a transverse section, in Figure 1, of one dividing strip or roll and
lates and capping at a connection thereof, and a side elevation thereof in
Figure 2.
Referring to the drawings, a are the roofing plates which say are of zinc or
other suitable metal-with their edges a¹ turned up and lying alongside the sides
of the dividing bar or roll b; c being the roofing boards to which the roll b is
fastened as usual. d is the cap which fits on the roll b, its turned down sides fitting
over the upturned edges a¹ of the plates a. e is the fastener. It is held in position
by being placed under the roll as shewn, and it holds the plates a down by being
bent down over the edges a¹. In fastening the capping d, the ends of the fastener e,

page_text: after they have been turned down over the edges a¹ of the plates a and the capping
placed in position, are turned up round and over the sides of the capping and then
into the horizontal position, (shewn in dotted lines), and one end turned round the
other, as shewn; after which they are knocked down together closely on the side
of the capping and rendered firm and secure. By this fastening, in the last
operation in applying it, wherein the ends of the fastening strips are knocked
down against the side of the capping, the strips are firmly drawn or brought into
contact with the capping and press it down into the desired position. Thus by a
plain single fastening strip e (which may be of the same metal as the plates and
capping), the capping is fastened and the plates held; and without any perforations
of any of the roofing plates or parts.
The invention is not restricted to the exact kind or form of roofing set forth
with reference to the drawings, as it may be applied to roofs which differ in this
respect, and in respect of the materials of which said main parts of the roofing
are made.
Of course in the roofing there will be as many of the fasteners in connection with
each capping as may be deemed necessary or desirable.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improvement, substantially as herein described in metallic roofing, consisting
of the employment in combination with the roofing plates and capping, of fasteners
consisting of a strip or plate, held by the dividing part on which the capping is
placed, and the ends of which are bent round and over the cap and one another;
for the purposes specified.
