Improvements Connected with Zinc or other Metal Roofing whereby
the Use of Solder in the Rolls and Fixings is entirely Dispensed
with, the said Invention being also Applicable for Covering Roofs
with other Material than Metal.
I, THOMAS WILLIAM HELLIWELL of Brighouse Yorkshire, Horticultural Engineer
do hereby declare the nature of my invention for "IMPROVEMENTS CONNECTED WITH
ZINC OR OTHER METAL ROOFING WHEREBY THE USE OF SOLDER IN THE ROLLS AND
FIXINGS IS ENTIRELY DISPENSED WITH THE SAID INVENTION BEING ALSO APPLICABLE
FOR COVERING ROOFS WITH OTHER MATERIAL THAN METAL," to be as follows
This invention relates to further improvements on prior Letters Patent granted to
mne bearing date the 30th of April A.D. 1884, No. 7015.
My present invention is intended to dispense with the use of solder in the rolls,
caps, and fixings used in the construction of zinc or other roofs.
According to the present system of metal roofing, it is usual to use certain hollow
caps which are marked F in my former specification above referred to, and are
employed for keeping down the sides of the sheets of zinc, such caps having their top
ends closed by soldering.
As I wish to dispense with the use of solder for purposes aforesaid I have devised
other means for making the ends of the said caps which is not only much neater
in appearance but much stronger and yet perfectly water tight.
Such being the nature and object of my Invention I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying Sheet
of drawings wherein A is the wood boarding which is usually employed to support
the metal covering, and D is the wood lath attached to the said support, B are the
sheets of zinc or other suitable material laid upon the said supports having their turned
up sides abutting against the wood laths D; and F is the cap employed to cover the
wood lath and the turned up edges of the sheets.
As stated above the top ends of these caps have been made weather proof by
soldering, but I prefer to make them weather proof in the following manner.

page_text: The end of the cap is cut and bent back as shewn at a in Fig. 1. I then cut a
piece of metal G of the shape shewn in Fig. 2 and fold or double it up as shewn in
Fig. 3. This folded plate Ġ is now taken and slided vertically down and over the
ends a (see Fig. 4) the tongue on the plate G being then bent under and over both
the side pieces a so as to hold the parts together.
b
In my former Specification herein referred to I employed certain saddles E, placed
continuous or at suitable distances apart under the cap F so as to prevent the making
of holes through the said cap.
One of the saddles I now make with a tongue c see Figs. 5 and 9 and place it so
that it can be brought under and wrapped around the folded plate G as seen in Fig. 6
thus holding down firmly the double plate G and as the saddle E is fastened to the
wood lath D by screw d it is impossible for the parts to move or become detached.
So far my invention has reference only to the making of the top end of the cap F,
but my improvements have also reference to the other end of the said cap, which end
is usually the one entering the trough or gutter to convey away the water.
In order to make this end of the cap without solder, I cut or form such end as shewn
in Fig. 7 the ends e are then folded inwards, whilst the extreme end fis doubled up
and the two sides g are folded over to cover the sides as shewn in Fig. 8 which is a
geometrical view of the thin end of the cap F folded and made according to my
invention without the use of solder.
Previous to these improvements the ends of the cap F and the ends of the sheets B
had to be nailed or screwed to the woodwork,. but by means of these improvements
such nails or screws are not now required in consequence of the saddles E occupying
the position shewn in the drawings, the method and means of attachment holding the
several parts firmly together, and giving the required strength.

I, THOMAS WILLIAM HELLIWELL, of Brighouse Yorkshire, Horticultural Engineer,
do hereby declare the nature of my invention for "IMPROVEMENTS CONNECTED WITH
ZINC OR OTHER METAL ROOFING WHEREBY THE USE OF SOLDER IN THE ROLLS AND
FIXINGS IS ENTIRELY DISPENSED WITH, THE SAID INVENTION BEING ALSO APPLICABLE
FOR COVERING ROOFS WITH OTHER MATERIAL THAN METAL," 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 further improvements on prior Letters Patent granted to
me bearing date the 30th of April A.D. 1884 No. 7015. My present invention is
intended to dispense with the use of solder in the rolls, caps, and fixings used in the
construction of zinc or other roofs.
According to the present system of metal roofing it is usual to use certain hollow
caps which are marked F in my former specification above referred to, and are
employed for keeping down the sides of the sheets of zinc, such caps having their
top ends closed by soldering.
As I wish to dispense with the use of solder for purposes aforesaid I have devised
other means for means for making the ends of the said caps which are not only much
neater in appearance but much stronger, and yet perfectly water tight.
Such being the nature and object of my invention I will now proceed to describe
the same more fully and for that purpose make reference to the accompanying sheet
of drawings, wherein A is the wood boarding which is usually employed to support
the metal covering, and D is the wood lath attached to the said support, B are the
sheets of zinc or other suitable material laid upon the said supports having their
turned up sides abutting against the wood laths D; and F is the cap employed to
cover the wood lath and the turned up edges of the sheets.
As stated above the top ends of these caps have been made weather proof by
soldering; but I prefer to make them weather proof in the following manner.
The end of the cap is cut and bent back as shewn at a in Fig. 1. I then cut a
piece of metal G of the shape shewn in Fig. 2 and fold or double it up as shewn in
Fig. 3. This folded plate G is now taken and slided vertically down and over the
ends a (see Fig. 4) the tongue 6 on the plate G being then bent under and over
the side pieces a so as to hold the parts together.
In my former specification herein referred to I employ certain saddles E placed
continuously or at suitable distances apart under the cap F so as to prevent the making
of holes through the said cap.
One of the saddles I now make with a tongue c see Figs. 5 and 9, and place it so
that it can be brought under and wrapped around the folded plate G as seen in Figs. 5

page_text: and 6, thus holding down firmly the doubled plate G, and as the saddle E is
fastened to the wood lath D by screw d, it is impossible for the parts to move or
become detached.
So far my invention has reference only to the making of the top end of the cap F,
but my improvements have also reference to the other end of the said cap, which end
is usually the one entering the trough or gutter to convey away the water.
In order to make this end of the cap without solder, I cut or form such end as
shewn in Fig. 7, the ends e are then folded inwards, whilst the extreme end is doubled
up, and the two sides g are folded over to cover the sides of the part when the
doubled part is bent over so as to touch the parts e.
Previous to these improvements the ends of the cap F, and the ends of the sheets B,
had to be nailed or screwed to the wood work, but by means of these improvements
such nails or screws are not now required in consequence of the saddles E occupying
the position shewn in the drawings, the method and means of attachment holding the
several parts firmly together and giving the required strength.
Having now particularly described and ascertained the nature of my said invention
and the manner in which the same is to be performed or put into practice I declare
that what I claim is:-
Firstly. The plate G cut, formed, or bent substantially, in the manner shewn in the
drawings.
Secondly. The plate G in combination with the cap F employed in the manner and
for purposes substantially as set forth.
Thirdly. The tongue c on the saddle E when used in combination with plate G and
cap F in manner and for purposes herein described and shewn in the drawings.
Fourthly. The cutting, forming, and bending of the end of the cap F which is
placed nearest the gutter, substantially as set forth and shewn in Fig. 7.
