method of forming the stop ends and saddle-pieces of the roll caps, integral with the
same, the said method being also applicable for forming the corners of the turned up
or flashed sides of each sheet of roofing or guttering.
In carrying my invention into practice, I form the half-stop ends of each sheet of
roofing, by operating upon the lower portion of each of the turned up or flashed
sides of and at the front of the said sheets, so as to form a fold on the same, and, at
the same time I bend the front edge of the sheet down at right angles or in the form
of a beaded or welted edge. I then turn the portions of the turned up sides, provided
with the folds just described, at right angles to and away from the said sides, or they
may be left projecting. By this arrangement 1 dispense.. with the usual corner
'pieces.
For forming the stop ends of the roll caps, I work down the metal at the end of
each of the same, but as the metal so worked is of greater superficial area than is
required to form the said stop end, 1 work it so that it is formed with a series of folds
or flutes, thereby giving it an ornamental appearance.
The saddle pieces of the roll caps, I also form in a somewhat similar manner, that
is to say, I first work up the metal at the end of each roll to form the saddle piece,
but as in the case of the stop ends this results in a portion of the metal so worked
being of greater superficial area than is required, I also form it with a series of
folds or flutes.
It will be obvious from the foregoing description of the formation of the stop
ends and saddle pieces of the roll caps, that the same principle can be applied to
forming the corners of the turned up or flashed sides of each sheet of roofing or
guttering, that is to say, when the said sides are turned up or flashed, a piece of
superfluous metal will be formed at each corner, which can be disposed of by forming
a series of folds or flutes in the same.

Improvements in Sheet-metal Roofing.
1, CHARLES THOMERSON of 263 Hackney Road in the County of Middlesex,
Plumber, do hereby declare the nature of this invention for. "IMPROVEMENTS IN
SHEET METAL ROOFING and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-:-
"
This invention relates to improvements in sheet metal roofing and has principally
for object a method of forming the corner pieces of the half stop ends of each sheet
of roofing and guttering integral with each said sheet, so that they do not require any
corner pieces soldering thereto as is usually the case.
It also relates to a new method of forming the step ends and saddle pieces of the
roll caps, the said method being also applicable for forming the corners of the turned
up or flashed sides of each sheet of roofing or guttering.

In carrying my invention into practice, I form the half-stop ends of each sheet of
roofing or guttering by operating upon the lower portion of each of the turned up or
flashed sides of and at the front of the said sheets so as to form a fold on the same,
and at the same time I bend the front edge of the sheet down at right angles or in the
form of a beaded or welted or square edge. I then turn the portions of the turned
up sides, provided with the folds just described, at right angles to and away from the
said sides, or they may be left projecting. By this arrangement I dispense with the
usual corner pieces.
For forming the stop ends of the roll caps 1 work down the metal at the end of
each of the same, but as the metal so worked is of greater superficial area than is
required to form the said stop end, I work it so that it is formed with a series of folds
or flutes, thereby giving it an ornamental appearance.
The saddle pieces of the roll caps, either separately or integral with the same, I
also form in a somewhat similar manner, that is to say, I first work up the metal at
the end of each roll to form the saddle piece, but, as in the case of the stop ends, this
results in a portion of the metal so worked being of greater superficial area than is
required, I also form it with a series of folds or flutes.
It will be obvious from the foregoing description of the formation of the stop ends
and saddle pieces of the roll caps that the same principle can be applied to forming
the corners of the turned up or flashed sides of each sheet of roofing or guttering,
that is to say, when the said sides are turned up or flashed, a piece of superfluous
metal will be formed at each corner which can be disposed of by forming a series of
folds or flutes in the same.
In order that my invention may be clearly understood reference is had to the
accompanying drawing, in which,
Figure 1 is a perspective view of a portion of a sheet of metal roofing with a
corner piece of a half stop end formed according to my invention;
Figures 2 and 3 are perspective views illustrating different stages in the manufacture
of the said corner piece;
Figure 4 is a similar view to Figure 1 illustrating a slight modification ;
Figures 5 and 6 are sections more fully described hereinafter ;
Figures 7 and 8 are a perspective view of a roll cap having a stop end and a
perspective view of a saddle piece respectively constructed according to my
invention;
Figure 9 is a perspective view of a corner between two turned up or flashed
sides of a sheet of metal roofing or guttering also formed according to my
invention ;
Figure 10 is a perspective view of part of a sheet metal roof embodying my
improvements.
Similar reference letters indicate the same parts throughout the drawing.
To form the half stop ends of each sheet of roofing or guttering 1 take one of the
said sheets having two opposite sides flashed or turned up. A portion of the said
sheet of metal roofing or guttering is shewn at a Figure 2, 6 representing one of the
said sides. c, Figure 3, is the fold which I form in each side 6 at the front of the
sheet and d is the front edge of the sheet which may be bent down at right angles as
shewn in the said figure or in the form of a bead as in Figure 1. e, Figure 3, is the
portion of the side 6 which I turn at right angles as shewn at Figure 1 so as to form
the corner piece of the half stop end or the said portion may be left projecting. As
shewn in Figure 1 the corner piece can be cut to the shape shewn. In practice I find
that by having only one flashed side and by operating upon it as herein before described,
so as to produce the result shewn in Figure 3, that by turning over the said sheet I
produce substantially the same result as in the said figure, except that the fold c is
outside the bend formed at the junction of the flashed side with the sheet a. This
result is illustrated in Figure 4 and it will be seen that what were the flashed side and
turned down edge in Figure 3 have now become the turned down edge and flashed
side respectively. The fold at the other end of the turned down edge d is then formed
in the same manner as that described, the said edge being then formed into a bead

page_text: similar to that shewn at Figure 1 or into a welted edge or square edge as illustrated
respectively by Figures 5 and 6 which represent sections of the said edges. This way
of forming the front edge d also applies to the front edge in Figure 1. The portion e
in Figure 4 can instead of being at right angles as shewn, be bent so as to project in
a similar manner to that described with reference to Figure 3.
In Figure 7f is the stop end which I form on the roll cap g by forming a series
of flutes h in the end of the same as shewn, and i, Figure 8, is the saddle piece the
superfluous metal of which is fluted as shewn at j. Instead of being separate the said
saddle piece can be formed integral with the roll cap.
In Figure 9 k represents one of the corners forming the junction between two of
the flashed or turned up sides of a sheet of roofing or guttering the said corner being
formed in a series of flutes as hereinbefore described.
In Figure 10 which represents part of a roof as hereinbefore described, a a represent
two contiguous sheets of metal roofing constructed as hereinbefore described with
reference to Figure 4, and g and i are a roll cap and saddle piece of the construction
shewn in Figures 7 & 8 respectively. As shewn in Figure 10 I sometimes make use
of the welt of the form shewn, one edge of the upper part of which engages
beneath the edge d of the roofing a while the rest of the upper part is fixed to the
woodwork m of the roof. This form of welt effectually prevents any water running
back under the metal sheets a a.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what
claim is:
(1). Forming the corner pieces of the half stop ends of sheet metal roofing or
guttering integral with the said roofing or guttering, substantially as described.
(2). Sheet metal roofing or guttering formed with folds so as to produce the corner
pieces of the half stop ends, substantially as described.
(3). Forming the corner pieces of the half stop ends of sheet metal roofing or
guttering substantially in the manner described with reference to Figures 23 and 1
of the accompanying drawing.
(4). Forming the corner pieces of the half stop ends of sheet metal roofing or
guttering substantially in the manner described with reference to Figures 23 and 4
of the accompanying drawing.
(5). Forming the stop ends of the roll caps of sheet metal roofing by fluting the
metal of the same substantially as hereinbefore described.
(6). Forming the saddle pieces for the roll caps of sheet metal roofing by fluting
the metal of the same, substantially as hereinbefore described.
(7). Forming the corners of the turned up or flashed sides of a sheet of metal
roofing or guttering by fluting the metal substantially as hereinbefore described.
(8). The improved sheet metal roof substantially as hereinbefore described and
illustrated in Figure 10 of the accompanying drawing.
Dated this 9th day of September 1890.
