deux Ecus, Merchant, and LOUIS JACOB OLIVIER BELLET, of 17, Rue Lepic, both

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co. Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows :-
This invention relates to the manufacture of glass, in the substance of which is
incorporated a grating of iron wires or other suitable material, in such a manner
that if the glass plate is fractured the broken pieces will not become detached but,
remain connected, being retained by the grating.
In carrying the said invention into practice a layer of fused glass of half the
thickness which the finished plate is to have is spread upon a table. Upon this layer
is placed a grating of iron wires or the like previously polished, the thickness of
which grating varies according to circumstances. This grating is then covered with
a fresh layer of glass over which a roller is passed.
By these operations a perfectly homogeneous glass plate is obtained with which is
incorporated a metallic network or grating which forms a body with the glass.
It is evident that the mode of manufacture can vary without departing from the
nature of this invention.

page_text: The product obtained can be employed in a raw state or be polished as required.
The plates can be used in the construction of windows, workshops, green-houses,
or roofs and generally in any cases where danger may arise through the breakage of
windows etc.
The form of the meshes of the metallic network can be indefinitely varied.
Glass formed by moulding or blowing may have incorporated therewith a metallic
network having for its object, in case of rupture, to prevent the falling of pieces and
accidents resulting therefrom.
I may employ wires of any desirable metal or material according to the various
applications of the invention.

Southampton Buildings, in the County of Middlesex 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 :-
This invention relates to the manufacture of glass in the substance of which is
incorporated a network or trellis of iron wires or other suitable material, in such a
manner that if the glass plate is fractured the broken pieces will not become detached
but remain connected, being retained by the metallic network.
In carrying the said invention into practice a layer of fused glass of half the
thickness which the finished plate is to have is spread upon a table.
Upon this layer is placed a network of iron wires or the like previously polished,
the thickness of which wires varies according to circumstances. This network is then
covered with a fresh layer of glass over which a roller is passed.
By these operations a perfectly homogeneous glass-plate is obtained with which is
incorporated a metallic network or grating which forms a body with the glass.
It is evident that the mode of manufacture can vary without departing from the
nature of this invention.
The product obtained can be employed in a raw state or be polished as required.
The plates can be used in the construction of windows, workshops, green-houses, or
roofs and generally in any cases where danger may arise through the breakage of
windows or the like.
The form of the meshes of the metallic network can be indefinitely varied without
departing from the nature of the invention or the mode of manufacture.
Glass formed by moulding or blowing may have incorporated there with a metallic
network having for its object, in case of rupture, to prevent the falling of pieces and
accidents resulting therefrom.
I may employ wires of any desirable metal or material according to the various
applications of the invention.

page_text: Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign Correspondents I declare that what I claim is :-
First. A plate or sheet of glass or other glass article having incorporated therewith
a metallic network or trellis, for strengthening the material and avoiding the scattering
or detachment of the pieces in case of breakage.
Second. The method of manufacturing sheets or plates of glass, consisting in
pouring upon a table a primary layer of melted glass, applying thereon a metallic
network or trellis the surface of which is preferably bright, and then covering the
same with a fresh layer of melted glass.
