said invention for "AN IMPROVED METHOD OF ORNAMENTING GLASS ARTICLES WITH
INLAID ORNAMENTS to be as follows:-
"
According to my invention I ornament glass articles with inlaid ornaments by
applying such ornaments, whether of open metal work or of other material, in
various ways to be presently described, upon the inner surfaces of the moulds in
which the glass is to be blown, so that on blowing the glass, this is forced into the
open spaces formed in the ornaments or left between the separate parts thereof,
whereby the said ornaments become firmly imbedded in the glass, and also, in the
case of certain materials, become cemented thereto by the heat.
For this purpose there may be employed either open metalwork ornaments,
formed by stamping, casting, pressing, or by galvanic deposit, or by plaiting or
soldering wire to form ornamental patterns, which are then placed in the mould so
as to lie against the sides thereof, or when the ornaments consist of separate pieces
of metal, porcellain, glass, mosaic, beads, precious stones, and the like, arranged in
patterns, such pieces are cementod with their faces to some material or fabric that
is destroyed by heat, which is then laid in the mould so as to present the back
surfaces of the pieces to the glass, when this is blown in as above described. The
ornaments are thus imbedded in, and, in some cases, cemented or melted on to the
glass, while the backing to which they were attached is cither destroyed by the
heat or subsequently removed by the use of solvents.
For conveniently arranging the said separate ornaments in patterns upon the
backing, a template may with advantage be employed, having recesses or holes
corresponding to the ornaments arranged in the required patterns and the
ornaments being placed in such recesses, the paper or other backing is then
cemented thereto.
The said ornaments may also be worked into the required patterns in a manner
similar to embroidery, the canvas or ground being afterwards destroyed. Or again,
they may be connected in a detachable manner to a framework corresponding in
form to the interior of the mould, the framework being if necessary built up of
separate pieces, so that it can be readily removed from the. glass article when
blown.

page_text: The framework should in this case be capable of being turned inside out so
that when the ornaments have been applied to the outer surface, it can be inverted
so as to bring the ornaments inside, in which position it is then placed in the
mould.
After moulding the glass article the portions thereof that protrude between or
through the ornaments may be cut or otherwise ornamented or painted, or they
may be ground flat, and if necessary portions of the ornaments may also be ground
off. If metal ornaments are employed, these may be subsequently gilt or otherwise
coated with other metals, the glass surfaces being provided with a protective coating
during such process, which is afterwards removed.

I, FRITZ HECKERT of 132 Middle-Petersdorf, Petersdorf, Silisia in the Kingdom
of Prussia, Germany, Manufacturer do hereby declare the nature of my said
invention for "AN IMPROVED METHOD OF ORNAMENTING GLASS ARTICLES WITI
INLAID ORNAMENTS" and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
According to my invention, I ornament glass articles with inlaid ornaments by
applying such ornaments, whether of open metal work or of other material, in
various ways to be presently described upon the inner surfaces of the moulds in
which the glass is to be blown, so that on blowing the glass this is forced into the
open spaces formed in the ornaments or left between the separate parts thereof
whereby the said ornaments become firmly imbedded in the glass and also in the
case of certain materials become cemented thereto by the heat.
For this purpose there may be employed either open metal work ornaments,
formed by stamping, casting, pressing or by galvanic deposit or by plaiting or
soldering wire to form ornamental patterns, as shewn by way of example at figs. 1
and 2 of the accompanying drawings, such ornaments being combined to form a
framework A A corresponding to the configuration of the glass to be ornamented
and which is introduced into the mould B and if required suitably fixed therein.
The glass is then blown into the mould in the usual manner, being thus made to
penetrate into the interstices a a of the ornaments and consequently to hold these
securely imbedded therein. In some cases the ornamental framework can itself
constitute the mould for the glass article as indicated at fig. 7.
For ornamenting the glass by means of separate ornaments such as mosaic, beads,
pieces of metal, glass, porcelain, agate or other objects the proceeding is as follows.
The design of the ornamentation is drawn or otherwise marked or engraved upon
a plate fig. 3, and the objects, such as beads &c are then placed according to the
design as at figs. 3 and 4, after which a sheet of paper or other material E coated
with adhesive substance is spread over the plate and pressed upon the ornaments,
so that these adhere thereto in the required positions.
The sheet E is then placed in the mould with the ornaments thereon presented
inwards as shewn at figs 5 and 6, and the glass is blown in so as to penetrate into
the interstices a of the pattern, as in the former case, so that when removed from
the mould, the glass appears bulged outwards between the ornamentation, which,
if of glass, will at the same time be practically melted on to the surfaco of the
article. The paper or other backing becomes burnt and its ashes are readily
removed.
Fig 3º shews another design for separate ornaments.
The ornaments can be applied to a backing or framework in a similar manner to
embroidery, in which case the backing or framework is afterwards inverted or
separated by cutting and put again together in an inverted position, in which it is
then placed in the mould so that the ornamentation is presented inwards. This
mode of operating is particularly advantageous for fine work,

page_text: Such ornamentation lies in relief upon the surface of the glass, the bulged surfaces
of which produce peculiar effects by reflection and refraction.
For further increasing the effect of ornamentation the bulged portions of the
glass can be cut with facets or they may be ground flat, in which case the orna-
mentation appears to be situated in corresponding recessed pattern cut on the
glass. In like manner portions of the ornamentation may be ground or cut away
so as to present disconnected parts.
The glass can also be further ornamented by painting, or the metal ornaments
can be gilt, bronzed, &c, in which latter case the glass surfaces are previously
covered with a protective coating.
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, The manufacture of glass articles ornamented with open metal work or wire
work, produced by blowing the glass into or between the said ornamentation so
that it bulges into the interstices or hollows thereof and thus secures it to the
surface of the glass articles, substantially as herein described.
2. The manufacture of glass articles ornamented with detached objects, arranged
in patterns-produced by securing the said objects arranged in patterns upon a
backing or framing,-which_is_then introduced into-the-mould.for the glass 50 that
the glass in being blown into the interstices of the ornamentation-causes_the_latter
to be imbedded thereon, substantially as herein described.
