"IMPROVEMENTS IN THE MANUFACTURE OF COLORED GLASS AND
METALLIC WINDOWS, APPLICABLE ALSO AS SCREENS AND SUCH LIKE PURPOSES.
FOR ORNAMENTATION." A communication from abroad by Ferdinand Dandois, of
Paris, France, Painter on Glass.
This Invention relates to certain novel and industrial applications for ornamental
or decorative purpose for colored windows or screens of coloured glass in combination
with sheets or pieces of metal whereby is secured the combination of the liveliness
of the tones of coloured glass with metallic brilliancy, the resultant decorative
effect not having as yet been utilized for ornamentation, and at the same time the
preservation for indefinite time of tones and brilliancy of metallic pieces, as well as
preservation of their shape is secured.
The process followed in carrying the Invention into practice is divsable into four
parts,
119
1. The form of the ornament to be made is cut out in any sheet metal of required
thickness either by means of a saw or acid; or this ornamental shape may be
secured by casting, stamping, or punching, and may be embossed, but it is
generally flat.
2. The metallic pieces for decoration receive partially or wholly a greater or less
brilliancy by means of polishing, lacquering, or japanning; it may be gilded, silver
plated, plated with nickel, bronzed, painted in vitrification, or the decoration pieces.
may be in wood metallized.or coated by means of gilding, silver plating, etc.
3. When the kind of metallic ornamentation is decided upon and ready, there is
to be selected the kind and tone of glass which will be used, and said glass may be
put either before or behind the ornamental pieces of metal; it may be fixed also
between the pieces of metal; sometimes one of the metallic pieces may be placed
between two white or colored glasses.
When glass is used to strengthen the metallic pieces it may be white; in other
cases it will be more or less colored.
The glass used may be engraved either by means of acid or otherwise, painted,
polished, opaque, frosted, pressed, veined, striped, in a word, all kinds of glass
presenting some originality may be used.
4. There are several means of joining the glass and metallic ornamental pieces
together according to the price to be charged and to the kind of decorative pieces

page_text: employed, and which I will now describe; (1) a lead setting for the ornamental pieces
is provided and is locked together by means of a wire which passes through the
exterior groove; or the parts may be closed by soldering, but not so as to close the
"outsides in order that they may be capable of being raised and laid down upon the
frame; (2), the framing together of the glass and inetallic pieces is effected by the
use of discs having open spaces, wherein will be placed the ornamental parts, and
on one side of the said discs is provided a flanged rim piece for holding up the
glass, and the other edge forms a rim or flange and rests upon the framing, and at
the intersections of the framing retaining discs, that is by screw bolts or pins, and
washers or soldered discs are provided for clamping the whole together; (3), glass
or glasses and metallic pieces are placed between two flat discs, which are screwed
together, the frame work being held between the said discs; in this case the
ornamental piece must be made on the spot. According to the nature of the frame
work, bolting may be used as well as screwing, soldering, nailing, or gluing; if
the frame work constitutes by itself a decorative piece, it serves the purpose of a
disc which is equally the case for all the means of junction of glass and decorative
metallic pieces; (4), by soldering which is similar to the method last described,
with the difference only that if there is employed lead, they solder or screw;
(5), the glass is placed upon the metallic decorative piece, which has all round a
projecting edge for stoppage, and it is covered either with a disc or with the frame,
then the whole is screwed or bolted together, the glass having been previously
bored to make passage for screw or bolt. By way of economy the metallic
decorative pieces may be fixed directly upon the frame; then they hold up the glass
or glasses on one side and a fat disc is put upon the other side; (6), the glass or
glasses are placed in a deep metallic piece which is fixed upon the frame by the
edge; the glass is fixed by means of putty; (7), the glass or glasses are placed in a
metallic bossed piece; the boss may contain another glass; this shows that there
may be change of the effect produced by modifying the shape of the surface of the
metallic piece or pieces. The discs are generally round because this form is the
most easy to be made, but any form may be used for metallic frame pieces or
retaining edges.
There is made with the seven means of junction above described, preferably the
cheapest and the easiest, any designs of metallic-decorative pieces which may be used
in any kind of ornamentation, viz., a Swiss cottage put in à grate, tiles, and so
forth.
The ensemble of metallic windows is made as ordinary glass windows of a
church, but instead of setting only glass, the glass and metal is set in superposed.
The liquid mastic of ordinary glass-windows of a church is used to prevent
infiltration or dust, and also for strengthening the whole.
The effect produced by the ensemble of metallic decorative pieces is very
striking; this may again be increased by covering the lead frame work, by some
metallic pieces polished or plated with nickel, etc., with or without sloped edge,
which are screwed or soldered with the said lead frame work; this kind of
ornamentation is also quite new.
In the fitting up of metallic windows, they may use any kind of ordinary screws,
but it is preferable to make use of a special screw which has been invented for that
purpose; this screwing may be considered as an ornament, and cannot be taken off
by mischief on account a special key being required therefor. The screw-head is
hemisperical and rests on a polygonal basis upon which the key works when used.
The nut is made similar to the screw head; it is by the means of the said nut that
the glass and metallic parts are joined together and fixed to the frame.
