I, THOMAS WILLIAM HELLIWELL, of Brighouse, Yorkshire, Horticultural Engineer
and Architect, do hereby declare the nature of my invention for AN IMPROVED
METHOD OF AND MEANS FOR SECURING AND FIXING ONTO ROOFS, FLATS, OR
SIDES OF BUILDINGS OR OTHER-STRUCTURES, SHEETS OF ZINC, COPPER PLAIN AND
CORRUGATED METAL OR OTHER SUITABLE MATERIAL," to be a as follows:→
This invention has reference to means to be employed in fixing. the metal
coverings of roofs and other surfaces. For the purpose of carrying out my inven-
tion I fix onto the wood or other supporting surface intended to be covered, a rib or
bar having a groove or slit formed in its upper side. Into this groove I insert and fix
the lower part of a Y shaped metal strip, the upper wings or edges projecting above
the grooved bar for purposes hereinafter explained. Metal sheets with turned up
edges for covering the structure are placed in position to be fixed having their
turned up edges abutting against the outer sides of the grooved bar, after which
the wings of the Y shaped bar are bent over or turned down for the purpose
of covering the turned up edges of the metal sheets, and making them secure
thereby.
Instead of employing the grooved bar aforesaid, two separate pieces of material
may be placed one on each side of the Y shaped strip and made secure thereto.
The bars whether employed whole or in parts may be rabbeted on the outer sides
for the purpose of receiving the turned up edges of the sheets of metal, thereby
preventing their being lifted by the wind.
Instead of employing the grooved bar or the detached pieces, the Y shaped strip
may be attached direct onto the supporting surfaces and used alone.

I, THOMAS WILLIAM HELLIWELL of Brighouse, Yorkshire, Horticultural Engineer,
and Architect do hereby declare the nature of my invention for AN IMPROVED
METHOD OF AND MEANS FOR SECURING AND FIXING ONTO ROOFS, FLATS, OR
SIDES OF BUILDINGS OR OTHER STRUCTURES SHEETS OF ZINC, COPPER, PLAIN AND
CORRUGATED METAL OR OTHER SUITABLE MATERIAL," and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:―

This invention has reference to means to be employed in fixing the coverings of
roofs, flats, or sides of buildings, the means I employ being simple in construction
and effective in operation.
1.
Such being the nature and object of my invention I will now proceed to describe
the same more fully and shew how the same may be put into practical operation.
In the accompanying drawings Fig. 1 is section of my improved method wherein
A is the wood or other supporting surface intended to be covered and B is a rib or
bar composed of wood or other material and secured to the said surface A by screws
or nails a.
The upper part of the bar B is made with a groove or slot into which I insert
the lower part of a Y shaped metal strip C (made secure therein by screws, nails,
or other suitable device b) the upper wings or edges c projecting above the grooved
bar for purposes hereinafter explained. The, sheets D to cover the structure are
then placed thereon, having their edges d turned up and abutting against the outer
sides of the grooved bars B, such bars being preferably rabbeted so as to receive the
turned up edges of the sheets as shewn in the drawings. After the sheets D are
placed in position as explained, the wings c of the Y shaped strip are then bent
down, whereby the several parts are covered, and a firm, compact, and water tight
covering is readily constructed.
Instead of the grooved bar B being made in one part as shewn in Fig. 1, it may
be,made in two parts as shewn in Fig. 2 and the metal strip C formed with a bulb
-see Fig. 3and instead of employing any grooved bar the metal strip C may be
formed as shewn in Fig. 4, in this case the bottom flango e is fastened direct to the
wood covering and the wings c bent down over the turned up edges d of the
sheets D as shown in Fig. 5,

page_text: 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. The employment of the bar B and Y,shaped strip C, when used in
combination with the turned up edges of the sheets D substantially as described
and shewn in Figs 1 and 2.
Secondly. The employment of the Y shaped strips, in combination with the
turned up edges of the sheets D substantially as herein described, and shewn in
Fig. 4.
