"IMPROVEMENTS IN THE MANUFACTURE AND FIXING OF VITREOUS MOULDINGS."
[A communication from abroad by Louis Alphonse Lherminier, of Paris, France.]
This Invention relates to the manufacture and fixing of mouldings made of
vitreous material, glass, crystal, or enamel, which may be employed as frames or
ornaments instead of those usually made of wood or of papier mâche and other
plastic materials. The vitreous mouldings for this purpose are either cast or
pressed while hot in suitable moulds presenting the desired profiles, with enrich-
ments hollowed out or in relief, and with surfaces either smooth or roughened as
may be desired. They may also have when necessary ribs to stiffen them.
The
glass employed may be colourless, or coloured glass or enamel may be used, and when
the moulding is transparent it may be bedded on coloured material or metal of
various designs which will shine through it. The mouldings may also be coloured,
gilt, or silvered wholly or partially on their external surfaces, and may be ground
or cut either internally or externally. For fixing the mouldings screws or bolts
are employed, these being made either with ornamental metal heads, or with their
heads enclosed in ornaments of glass or enamel of a character corresponding with
the moulding, and such bolt heads may be made so as to cover the jointings of the
parts of the moulding. When it is desired to conceal the fixing, screwed studs are
secured in the back of the moulding while it is being cast or pressed into shape,
these studs projecting sufficiently far to receive nuts or internally screwed bolts
whereby the mouldings are fixed to their beds. According to another method
which may be adopted when the shape of the moulding admits of it, the edges of
metal plates secured to the bed are bent and pressed over the edges of the moulding
so as to hold it firmly, and these metallic edges may themselves bo made to orna-
mental patterns. In many cases the mouldings may be cemented to their beds, as
when they are applied to walls, cornices, and other parts of structure, but when
they cannot conveniently bo secured by cement it is preferred to secure them as
above described by bolts, screws, or bent metal plates to bars of wood which can
be jointed together to form frames and such like constructions.

'IMPROVEMENTS IN THE MANUFACTURE AND FIXING OF VITREOUS MOULDINGS."
A communication from abroad by Louis Alphonse Lherminier, of Paris, France.
This Invention relates to the manner and fixing of mouldings made of vitreous
material, glass; crystal, or enamel, which may be employed as frames or ornaments
instead of those usually made of wood or of papier mache and other plastic
materials. The vitreous mouldings for this purpose are either cast or pressed while
hot in suitable moulds presenting the desired profiles, with enrichments hollowed
out or in relief, and with surfaces either smooth or roughened as may be desired,
or such ornamentation may be produced by cutting, engraving, etching, or grinding.
They may also have when necessary ribs to stiffen them. The glass employed
may be colourless, or colored glass or enamel may be used, and when the moulding is
transparent it may be bedded on coloured material or metal of various designs which
will shine through it. The mouldings may also be coloured, gilt, or silvered wholly
or partially on their external surfaces, and may be ground or cut either internally
or externally. For fixing the mouldings, screws or bolts are employed, these being
made either-with-ornamental-metal heads. or with their heads enclosed in
ornaments of glass or enamel of a character corresponding with the moulding, and
such bolt heads may be made so as to cover the jointings of the parts of the
moulding. When it is desired to conceal the fixing, screwed studs are secured in
the back of the moulding while it is being cast or pressed into shape, these studs
projecting sufficiently far to receive nuts or internally screwed bolts whereby the
mouldings are fixed to their beds. According to another method, which may be
adopted when the shape of the moulding admits of it, the edges of metal plates
secured to the bed are bent and pressed over the edges of the moulding so as to
hold it firmly, and these metallic edges may themselves be made to ornamental
patterns. In many cases the mouldings may be cemented to their beds, as when
they are applied to walls, cornices, and other parts of structure, but when they
cannot conveniently be secured by cement it is preferred to secure them as above
described by bolts, screws, or bent metal plates to bars of wood, which can be
jointed together to form frames and such like constructions.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 to 4 shew various forms of mouldings constructed of vitreous material,
glass, or other similar material according to this Invention. Figs. 7 and 8 shew
similar mouldings with figured faces. Figs. 3, 4, 5, 6, 7, and 8 shew that the
mouldings may be strengthened either by making them thicker or with solid or
ribbed backing; such mouldings can, according to the material employed, be made
of any desired colour, either opaque, or translucent, or transparent, and they may
be made to imitate various materials, such as wood mouldings and the like, and they
may be composed of various different kinds of material, or of materials of different
colours combined either in layers or otherwise. They may also have designs painted

page_text: mouldings may be intersected at one or more points by mouldings of a different
profile projecting from the face thereof, Figs. 9 and 10 serving to shew the two
different profiles at Fig. 11, and Figs. 12 and 13 shewing the two profiles
of Fig. 14. The mouldings may also have other projecting ornamentations fixed
on their surfaces either for covering joints or otherwise. The fixing of such
mouldings may be effected either by cementing, plastering, or other adhesive
means, or by screws or bolts, which may either be secured to the inner face of the
moulding or be made to pass through holes therein. In this case the outer head
of the bolt is made of an ornamental character barmonising with the moulding, for
which purpose it may be provided with a vitreous or enamelled surface. Figs. 15,
16, 17, 18, and 19 shew various arrangements and forms of such bolts with orna-
mental heads; those shown at Figs. 17, 18, and 19 being intended to pass through
the wall or surface against which the moulding is to be fixed, while in the arrange-
ment shewn at Fig. 21 a plug of metal or wood is secured in the said wall or
surface into which the screw securing the moulding is screwed; or, as at Fig. 20, a
screwed pin is secured in the back of the moulding and a bolt with a female thread
is passed through the surface on which the moulding is fixed and is scrowed on to
the pio.
In securing the moulding by means of bent metal plates hereinbefore referred to,
wood strips are, by preference, fixed against the wall or surface, and to the edge of
such wood strips are fixed strips or bands of metal with their edges projecting a
sufficient distance beyond the face of the wood. Upon the latter is then placed the
moulding and the edge of the metal strip, which projects somewhat beyond the
edge of the moulding, is then bent over the latter, so as to cover it slightly and
thus hold it securely. Or a metal plate or band of greater width than the moulding
may be fixed on the wood strips and its projecting edges be bont over the edges of
the moulding when this is placed thereon.
Having thus described the nature of the said Invention and in what manner
the same is to be performed as communicated to me by my foreign correspondent,
I claim,-
First. The herein described improved manufacture of vitreous mouldings.
Second. The means herein described for fixing such vitreous mouldings to walls
or other surfaces to which they are to be attached.
In witness whereof, I, the said John Imray, have hereunto set my hand and
seal, this Eighth day of October, in the year of our Lord One thousand
eight hundred and eighty.
