I, RICHARD 'SMETHURST SMETHURST, of 96, New Lane, Patricroft, in the
County of Lancaster, Artist in Stained Glass, do hereby declare the nature of
this invention to be as follows':
This invention relates to the manufacture of an improved material suitable
for use as a waterproof covering for roofs, or as a substitute for glass for windows,
and for other like structural purposes, where strength, lightness durability, and
more or less transparency are required.
L
My invention consists in the combination with woven metal wire cloth or
perforated sheet metal, or other suitable open, meshed, or reticulated fabric, of
a solution in hot water, of gelatine which has, been chemically treated with
formic, aldehyde or other suitable acid preparation or compound of aldehyde in
such a way as to render the same insoluble and non-absorbent to give it increased
tensile
ile strength, and to prevent it from assuming a softened or pasty condition
by exposure to sun, rain, or moisture.
The combination of the woven wire cloth or other perforated, meshed, or
reticulated fabric with the prepared gelatine may be effected by applying
repeated coats of the latter thereto, either by dipping, brushing, rolling or
otherwise, until all the meshes, perforations or reticulations, of the fabric have
been completely filled in and both sides thoroughly coated therewith, each.
separate coating being well dried before applying another thereto..

The prepared gelatine may either be used in an uncolored state so, as to admit
a large amount of clear light, or it may be tinted more or less, by, the admixture
therewith of any suitable coloring matters, or if preferable be rendered more
or less opaque, or otherwise ornamented.
トビー
The combined material can be rolled or bent, without injury and may
be used as a more or less transparent and perfectly waterproof roofing
material, or as a substitute for glass for windows, or partitions, and for a
variety of other like structural purposes where lightness, strength, durability,
impermeability to moisture, and transparency in a greater or less degree coupled
with absence of brittleness, are desired, and for a variety of other useful and
ornamental purposes too numerous to mention.

I, RICHARD SMETHURST SMETHURST, of 96, New Lane, Patricroft, in the
County of Lancaster, Artist in Stained Glass, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:—
This invention relates to the manufacture of an improved material suitable
for use as a waterproof covering for roofs or as a substitute for glass for windows
and for other like structural purposes where strength, lightness, durability -and
more or less transparency are required.
My invention cousists in the combination with woven metal wire cloth or
perforated sheet metal or other suitable open meshed or reticulated fabric of
a solution obtained by steeping gelatine in water and dissolving by heat adding
when hot ten per cent. of water to five per cent. or thereabouts of formic aldehyde
or other suitable acid or gaseous preparation or compound of aldehyde.
The combination of the woven wire cloth or other perforated meshed or
reticulated fabric with the solution hereinbefore described may be effected
either by dipping the material in the mixture or running the mixture through
the material and then drying, or by brushing, rolling, or otherwise applying
until all the meshes, perforations or reticulations of the fabric have been com-
pletely filled in and both sides thoroughly coated therewith, each separate
coating being well dried before applying another thereto. The material can
be treated with formic aldehyde atter being coated with the gelatine solution,
either by dipping in formic solution or submitted to any formic aldehyde or
acid base or gas so as to render the same insoluble and to a great extent non-
absorbent thereby increasing the tensile strength of the material and preventing
its assuming a soft or pasty condition.
A coat of any suitable varnish or oxidised oil may be applied to the surface
for very wet climates: Glycerine or mucible oils can be added if required to
soften and make the material more elastic.
The prepared gelatine may either be used in au uncolored state so as to admit
a large amount of clear light or it may be tinted more or less by the admixture
thorewith of any suitable colouring matters or if preferable be rendered more
or less opaque or otherwise ornamented.
The combined material herein described can be rolled or bent without injury
and may be used as a more or less transparent and perfectly waterproof roofing
material, or as a substitute for glass for windows or partitions and for a
variety of other like structural purposes where lightness, strength durability
impermeability to moisture and transparency in a greater or less degree coupled
with absence of brittleness are desired and for a variety of other useful and
ornamental purposes too numerous to mention.
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: -
1. An improved material to be used as a waterproof covering for roofs or as
a substitute for glass or other like purposes consisting in the combination with
woven metal wire cloth, or perforated sheet metal, or other suitable open meshed
or reticulated fabric of a solution of gelatine which has been chemically treated

page_text: with formic aldehyde or other suitable acid or gaseous preparation or compound
of aldehyde, substantially as and for the purpose herein before described.
2. Treating the material hereinbefore named with formic aldehyde or acid
base or gas after being coated with the gelatine solution in the manner and for
the purpose substantially as described.
