An Improved Means and Method of Fixing Sheets of Zino, Lead,
Copper, or other Suitable Material onto Roofs, Flats, and Sides
of Buildings, Structures, or other Places where Applicable.
I, THOMAS WILLIAM HELLIWELL, of Brighouse, Yorkshire, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention consists in a new method of fixing sheets of zinc, or other suitable
material onto roofs or other parts of buildings by means of which I can dispense with
the usual wood roll and metal cover, and with all the fastenings belonging thereto
which are now commonly used when fixing sheets of zinc.
In carrying out my invention I take a sheet of zinc and fold over the vertical edges
thereof, the folded edges being preferably opposed to each other.
This sheet of metal is now placed upon the wood work of the structure and held
down and kept in position by a strip of metal which may or may not be of the same
length as the sheet. One part of this strip is attached to the structure by nails or
other means,
whilst the other part is arranged to press upon the folded edges of the
sheet placed under it. Another sheet of zinc is now taken with its vertical edges
folded over as in the previous case, one edge of which is placed or hooked under the
edge of the strip and of the folded edge of the sheet already under the strip, which
strip is now entirely covered over by the sheet last fixed. Another strip of metal is
now taken and fixed to the structure with one edge over and pressing upon the folded
edge of the sheet last fixed, and then another sheet of metal with folded edges is placed
in like manner to those already described and so on as many as may be required are
laid side by side to cover the structure.

page_text: To prevent the sheets of metal slipping down I indent or cut small pieces out of the
folded edges of the sheets at suitable distances apart, into which indents or openings
I bend a corresponding projection cut out of the edge of the strip, which effectually
prevents the sheets slipping down. The top and bottom edges of the sheets of metal
are fixed in a similar manner to the vertical edges, as are also the edges of the sheets
where they join up to valleys or other gutters and hips.
By this method of fixing sheets of zinc, or other material no wood roll or cap is
required, as is now the case, consequently the cost is reduced, besides the surface
of the structure is comparatively flat, instead of ridges caused by the wood rolls
and caps.

I THOMAS WILLIAM HELLIWELL of Brighouse, Yorkshire, 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 consists in a new method of fixing sheets of zine, or other suitable
material onto roofs or other parts of buildings by means of which I can dispense with
the usual wood roll and metal cover, and with all the fastenings belonging thereto,
which are now commonly used when fixing sheets of zinc.
In carrying out my invention I take a sheet of zinc or other suitable metal and fold
over the vertical edges thereof, the folded edges being preferably opposed to each
other. This sheet of metal is now placed upon the wood work of the structure and
held down and kept in position by a strip of metal which may or may not be of the
same length as the sheet. One part of this strip is attached to the structure by nails,
screws, or other means, whilst the other part is arranged to press upon the folded
edges of the sheet placed under it. Another sheet of zinc is now taken with its
vertical edges folded over as in the previous case, one edge of which is placed or
hooked under the edge of the strip and of the folded edge of the sheet already under
the strip, which strip is now entirely covered over by the sheet last fixed. Another
strip of metal is now taken and fixed to the structure with one edge over and pressing
upon the folded edge of the sheet last fixed, and then another sheet of metal with
folded edges is placed in like manner to those already described, and so on as many
as may be required are laid side by side to cover the structure.
In order that my invention may be better understood I herein make reference to
the accompanying sheet of drawings illustrative thereof, wherein Fig. 1 represents a
wood structure A covered by plates according to my invention. B represents the
sheets of zinc or other material with two of their opposing sides turned over as seen
at a. and b. Fig. 2.
In commencing to cover the roof or surface A, a plate B is taken and placed upon
the roof as shewn in Fig. 3. I then take a narrow strip of metal or other material C
(see Fig. 4) one edge of which is fastened to the structure by nails c or other means;
whilst the other part or edge of the strip is allowed to press down upon the turned
over edge a of the sheet B. When this is done another sheet B (with its opposite
side turned down as already described) is employed and the hooked side b inserted
under the turned over edge a as seen in Fig. 1, and then a third sheet, and so on, one
after another.
By this means the narrow strip is entirely covered, and the structure made water
tight without external fastenings. The tops and bottoms of the sheets may be secured
in like manner.
To prevent the sheets of metal slipning down I indent or out smell nicons and 1

page_text: folded edges of the sheets at suitable distances apart, into which indents or openings
bend a corresponding projection cut out of the edge of the strip, which effectually
prevents the sheets slipping down. The top and bottom edges of the sheets of metal
are fixed in a similar manner to the vertical edges, as are also the edges of the sheets
where they join up to valleys or other gutters and hips.
This part of my invention is shewn in Fig. 5 where the edge of the sheet B is
indented as shewn at d and the strip C is correspondingly indented as shown at e. In
Fig. 6 the plate B and strip C are shewn placed together, where the projections e are
turned under the recessed indents d of plate B, by which means the two plates could
not fall away from each other.
By this method of fixing sheets of zinc, or other material no wood roll or cap is
required as is now the case, consequently the cost is reduced, besides the surface of
the structure is comparatively flat, instead of ridges caused by the wood rolls
and caps.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
Firstly. For covering roofs and surfaces, the plate B with both its vertical edges
turned over as shewn in Fig. 2.
Secondly. The use of sheet B with both its vertical edges turned over, in combination
with strip C in manner substantially as set forth.
Thirdly. The combination of plates B. C and B with the vertical edges of sheets B
turned over all being arranged substantially as set forth.
Fourthly. The employment of plates such as B and C having their vertical edges
indented as shewn in Fig. 5 for the purpose of preventing the said plates from falling
away from each other.
Fifthly. The method or system of covering surfaces as herein shewn and described
whereby the roll and metal cover usually employed are dispensed with.
