PROVISIONAL SPECIFICATION.
Glass Tiles suitable for being used in conjunction with Sheets of
Corrugated Iron in the Making of Roofs and the like.
I, JOHN ISODORE DE JONGH, Asste. M.I.C.E., of San José, Costa Rica, and
care of Messrs. Chalmers Guthrie & Co., 9 Idol Lane, London, do hereby declare
the nature of this invention to be as follows:-
At the present time when glazed openings have to be formed through corrugated
iron roofs and the like for admitting light the edges of the opening have a strong
frame secured around them to carry the sheet of glass by which the opening is to
be covered over. This is expensive and in many cases inconvenient.
According to my invention form tiles of glass corrugated to conform to the
corrugations of the corrugated sheet iron, and at the top of the tiles I form
lugs projecting downwards from their under side at the ends of the several
corrugations.
These serve to hook over the horizontal wooden or other supports by which the
roofing sheets are ordinarily carried and the tiles are held in place by the lugs so
hooking over the horizontal supports and by their upper edges being overlapped by
the lower edges of the corrugated iron sheets which are above them. They may
also be further secured at their lower edge. The tiles may be formed to any
desired width and at their side edges are so shaped that they may lap over one
another without interfering with the corrugations in any two adjoining tiles being
at uniform distances apart so that both such adjoining tiles may be overlapped by
the edge of a single sheet of corrugated metal.

COMPLETE SPECIFICATION.
Glass Tiles suitable for being used in conjunction with Sheets of
Corrugated Iron in the Making of Roofs and the like.
I, JOHN ISODORE DE JONGH, Asste. M.I.C.E., of San José, Costa Rica, and
care of Messrs. Chalmers Guthrie & Co., 9 Idol Lane, 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 :-
At the present time when glazed openings have to be formed through corrugated
iron roofs and the like for admitting light the edges of the opening have a strong
frame secured around them to carry the sheet of glass by which the opening is to
be covered over. This is expensive and in many cases inconvenient.
According to my invention I form tiles of glass corrugated to conform to the
corrugations of the corrugated sheet iron.
These I secure at the top to the horizontal wooden or other supports by which
the roofing sheets are ordinarily carried. They may also be further secured at
their lower edge. The tiles may be formed to any desired width and at their side
edges are so shaped that they may lap over one another without interfering with the
corrugations in any two adjoining tiles being at uniform distances apart so that
both such adjoining tiles may be overlapped by the edge of a single sheet of
corrugated metal.
Figure 1 of the drawings annexed is a cross section of a portion of two glass tiles
constructed according to my invention. .

page_text: Figure 2 is a part plan view of the tiles.
The tiles are corrugated as shewn in Figure 1 and to admit of their being secured
to the rafters of a roof countersunk holes A are formed through them for screws or
bolts to be passed through. The countersunk holes may conveniently be formed
through them by means of a sand blast-
-a process now well understood.
To form the corrugated tiles I preferably take a flat plate of rolled or plate
glass and whilst it is still soft and plastic place it onto a number of parallel bars
which are rounded at the top and are a distance apart equal to the distances apart
of the corrugations which are to be produced and then I bring down on to the top
surface of the glass a series of other parallel bars which are intermediate of the
bars in the lower set and so the sheet of glass gets bent into the desired corrugated
form.
Other suitable means may however be adopted for making the desired corrugations
in the tile.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
A corrugated glass tile suitable for being used in conjunction with sheets of
corrugated iron in the making of roofs and the like substantially as described.
