PROVISIONAL SPECIFICATION.
A Zinc or other Metal Clip for Fastening the Roll Caps of Metal
Roofing Sheets.
We CHARLES THEODORE PLANT FRANCIS JOHN WILLIAM JACKSON and
CHARLES ROBERT_WEBB trading as Plant Jackson & Co. Zinc and Galvanized
Iron Workers 66 Dale End Birmingham, do hereby declare the nature of this
invention to be as follows:-
:-
A double folded metal clip for securing roll caps over the joints of zinc or other
metal roofing sheets, wherever same is turned up against the sides of rolls dividing
the sheets, without the use of solder or external screws or nails. The said metal
clip allowing for the expansion or contraction of the roll caps and at the same time
making a sound and watertight joint. The said clip consists of a flat piece of
metal 7 in. long by 4 in. wide, folded 3 in. over, then folded 1 in. back again,
forming an inner and outer groove for metal rolls to slide in. The clip is secured
by two screws to wood work of roof.

A Zinc or other Metal Clip for Fastening the Roll Caps of Metal
Roofing Sheets.
We CHARLES THEODORE PLANT, FRANCIS JOHN WILLIAM JACKSON, and
CHARLES ROBERT WEBB, trading as Plant, Jackson & Co., Zinc and Galvanised
Iron Workers, 66 Dale End, Birmingham, 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:-
A double folded metal clip for securing roll caps over the joints of zinc or other
metal roofing sheets, wherever same is turned up against the sides of rolls dividing
the sheets, without the use of solder or external screws or nails. The said metal
clip allowing for the expansion or contraction of the roll caps and at the same time
making a sound and watertight joint. The said clip consists of a flat piece of
metal 7 inches long by 4 inches wide folded 3 inches over, then folded 1 inches
back again, forming an inner and outer groove for metal rolls to slide in. The
clip is secured by two screws to wood work of roof.
In order to more clearly explain this our invention we have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference,
similar numbers referring throughout the several views to the same thing or part.
Fig. 1, is a side elevation of this our invented clip.
Fig. 2, is a plan view of the said clip.
Fig. 3, is a sectional view of the clip as seen on line A—B (Fig. 2).
Fig. 4, is a sectional view of a portion of roofing &c. to which this our invention

page_text: Fig. 5, is a side view showing this our invention in position upon the roll &c. of
the roof.
Fig. 6, is a sectional view of same upon line C-D-E.
Fig. 7, shows a modified shape of clip as suitable for instance to corrugated
sheets.
8, 8, are the roofing boards or other supports, carrying the roofing sheets 9, 9.
10, is the roll, which divides the sheets 9, 9ª, and against which the edges 9" and 9º,
are turned or bent. It will be of course understood that this roll may be of any
desirable sectional shape. 11 and 11ª are the roll caps which embrace the roll and
the two turned up edges 90 and 9 of the roofing sheets. 12, is the double folded
clip which forms the subject matter of this our invention, as follows:-
We take a piece of metal (generally zinc) of suitable size, according to the size
of roll &c., but generally about seven inches by four and half inches. This is
doubled over longitudinally at 13, and again at 14, so as to form cavities 15 and 16.
It is then bent and shaped transversely to accommodate the roll or the sheets, or
both. Screw holes 17, 17, are provided by which the said clip may be secured to
the roll 10, by screws 18, 18.
As before intimated this clip may be modified to suit the jointing of sheets other
than those shown, for instance it may be adapted for carrying corrugated sheets as
seen in Fig. 7, in which the said clips would be used at intervals (say about a foot
apart).
Its action is somewhat thus :-The sheets 9, 93, are placed in position as shown.
The uppermost roll cap 11ª, is now fixed, when the clip 12, is pushed forward upon
the cap 11", in the direction shown by the arrow (see Fig. 6). The screws 18, 18,
are now inserted. Next the cap 11, is similarly pushed into position, and the
process and arrangement repeated at the joints and so on, of the said roll caps.
The particular order of arrangement in fixing may be varied if desired.
It will thus be seen that ample provision is made for expansion or contraction,
and at the same time its construction and arrangement is such that constitutes its
being sound and practically watertight.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The double folded clip constructed and arranged substantially as herein described
and illustrated and for the purposes specified.
