PROVISIONAL SPECIFICATION.
Improvements in Sheet Metal Roofing.
We, JOSEPH MORTON KILLICK, Director of Treggon and Company Limited,
and GEORGE LONGHURST, Foreman to the said firm, both of York Works,
Brewery Road, in the County of London, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in sheet metal roofing, and its main object
is to render the use of solder unnecessary.
In carrying it into effect, the roll is tapered towards the front and the sheets
flushed or flanged up its sides and in front of its nose or front end. The back
portion or saddle piece of the cap is flanged upwards and laterally. The front
portion or stop end of the cap is made in one piece, the front part thereof, viz., that
which stands in front of the roll being deep enough to furnish a small trough which
is produced by inwardly curving its bottom edge. The object of this trough is to
prevent the drip syphoning or otherwise making its way underneath the roofing
sheets. The latter are for the same reason made with a bold circular bead along
their front edge by turning or rolling their front edges inwards which beads the
troughs above mentioned embrace when the front portions of the caps are pushed
into position.
The cap is made with grooved or equivalent edges.

COMPLETE SPECIFICATION.
Improvements in Sheet Metal Roofing.
We, JOSEPH MORTON KILLICK, General Manager to Treggon & Company,
Limited, and GEORGE LONGHURST, Foreman to the said firm, both of York
Works, Brewery Road, in the County of London, 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 :-
Our invention relates to improvements in sheet metal roofing; and its main
object is to render the use of solder unnecessary throughout. The said main, as
well as sundry subsidiary, objects are attained by the distinctive constructions
hereinafter detailed and claimed. And in order that the said invention, and the
best means of carrying it into practical effect, may be thoroughly understood,
we will now particularly describe them, referring in so doing to the accompanying
drawings which are to be taken as part of this Specification and read therewith.
Fig. 1 is a perspective view of an upper roofing sheet.
Fig. 2 is a perspective view of a lower roofing sheet.
Fig. 3 is a perspective view of a combined saddle piece and roll cap.
Fig. 4 is a perspective view of a combined stop end and roll cap of either a top
or a lower roofing sheet.
Fig. 5 is a side elevation, partly in section; Fig. 6, a plan corresponding
therewith, and
Fig. 7, a perspective view of top and lower roofing sheets illustrating the details
of construction.
Fig. 8 is a vertical section, on an enlarged scale, taken on the line Y-Z of

construction, and the beaded flashings B, illustrated in Figs. 5 and 6, are the same
that have hitherto been in common use in the trade.
C are the rolls. Hitherto these have been of the same cross section throughout
their entire length; but, according to our invention, we taper the front end of the
roll by cutting the sides away equally, so that the two taper surfaces c, c, produced
by such cutting, meet in a vertical line or narrow plane c¹ as distinguished from the
vertical butt, or almost square, end heretofore known.

the returned or forwardly bent flanges or welts on the turn ups e.
So far, the said sheets are the same as have hitherto been in use. But, in
respect of their widths, the sheets hitherto in use have had parallel sides to match
the rolls. Special pieces were used to guard the butt end above referred to of the
wood roll, and the formation of the nosing or beaded edge along the front edge of
the sheet also involved the soldering in of what were known as "half stop ends"
the corners of the sheet.
at
Now, according to our present invention, both these devices of special pieces and
half stop ends are dispensed with by the sheets being tapered or flared outwards,
right and left, at a point, say from 3 to 6 inches, from the front edge, (see Figs. 1,2
and 7,) the side turn ups d duly following the said taper or flare. The two
outwardly tapered or flared turn ups of two adjacent roofing sheets are therefore
adapted to meet in front of the respective improved roll, and will do so when they
are laid in their permanent position upon the wood flat A, as illustrated in Fig. 7,
thereby efficiently guarding the front end c¹. is the beaded drip or nosing. It
is nearly a complete circle in cross section, and is made sufficiently bold for its
terminal edge to stand well under the edges of the welts and f¹, but of
which welts it stops short for a short distance, so as to compel the rain water
from the respective upper sheet to drop on to the sheet below clear of both welts
and turn up e.
The top corners of a sheet, where the side turn ups d join the back turn ups e
or el, as the case may be, are not cut out and the cut edges united by soldering, but
projecting double (i.e. two-sheet) triangles i, i, are produced. These are adapted
to stand behind the top end of the roll, which stops short of the risers or vertical
members of the flat A to admit them.
jj are shoulders formed upon the side turn ups d by cutting away the top edges
thereof backwards for a convenient distance up the parallel portion of the turn
up, and k, k are a pair of clips adapted to engage with the side turn in
front of the said shoulders, respectively, for the purpose of keeping the sheet in its
place.
ups
These clips are made fast to the bottom sides, or to the bottom of the roll. If
preferred, any pair of them may be the ends of a strip of metal k passed under the
roll, as illustrated in Fig. 8. There may be as many pairs of clips and shoulders.
to a pair of adjacent side turn ups as may be desired.
The external side turn ups of the outside sheets, of course, follow the line of the
end of the roof, to which they are fixed in any convenient way.
I is the saddle piece which is formed, by stamping, in one piece with the upper
portion m of the roll cap. Both sides of this portion have grooves m³ formed upon
their bottom edges. These grooves are continued up along the sides of the saddle
piece where they are closed so as to give it a double edge up both its sides. The
lower portion n of the roll cap may be as long as is necessary. The front end of it,
commonly known as the stop end, o, is formed by folding it down and into the
sides, in the well known manner. P is its beaded edge. It is nearly circular in
cross section and is of a proper size to spring over and clutch the beaded edges of
the two sheets underneath it. The bottom edges of the portion n of the roll
are also grooved up in the same way as are the bottom edges of the upper portion m
to within a short distance of the end, where the sides of the cap are cut away,

page_text: producing a taper 9 on each, for the purpose of facilitating the engagement of the
lower portion n with the upper portion in of the cap.
These grooves are engaged by the clips aforesaid as the roll cap is being fixed.
This engagement holds the cap in position, whereby full provision is made for
expansion and contraction while bulging at the sides is rendered impossible.
We do not confine ourselves to the number of pieces of which any roll cap may
be made. There will not, however, be less than two, one carrying the saddle piece,
and the other the stop end.
The saddle piece of any lower roll cap carries a plain welt f' as indicated by the
dotted lines of Fig. 3. This welt is in a plane parallel with that of the welts f, and
is accordingly adapted to lie under and close up to the adjacent welts of the
respective sheets, where and with which it is gripped by the beaded edges of the
upper sheets when the latter are fixed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is,
1. The combination of roofing sheet and beaded front edge as set forth.
2. The combination of roll having the sides of its front end cut away so as to
produce a taper, and a roofing sheet with its side turn ups flared or tapered outwards,
the adjacent turn ups of the roofing sheets on each side of the roll being thereby
adapted to meet in front of the roll, as set forth.
3. The combination in a roofing sheet, of outwardly tapered or flared front, side
turn ups duly following the same taper or flare and beaded front edge, whereby the
turn ups and edges of the sheets on each side of a roll are adapted to meet in front
of the roll, as set forth.
4. A saddle piece formed by stamping in one piece with a portion of the roll cap,
the latter having grooved edges which merge into doubled edges on the sides of the
saddle piece, as set forth.
5. The combination with the upper portion or portions of a roll cap having
grooves on it or their edges and tapers on the sides of the lower portions
adapted to enter said grooves, and grooves on the edges of the lower portions, as
set forth.
6. The combination of roll cap having grooves on its edges and clips fixed
to the rolls adapted to enter the said grooves and to hold the cap and sheets,
as set forth.
