Ornamenting. Rods of
glass, singly or in groups, are twisted while soft by mechanism
comprising a revolving chuck and a stationary holder, such as is
described in Specifications No. 1739, A.D. 1867, and No. 2016. A.D.
1870, [Abridgment Class Metals, Cutting &c.]. A trough or other support is provided for the rods during
twisting. The rods may be twisted from one end only or from both ends
simultaneously in the same or opposite directions, the centre portion
being fixed, if desired. Tubes may be twisted in the same way for use
for gas brackets or arms &c. The rods should have one or more
longitudinal ribs or projections of angular or curvilinear
cross-section, and ornamental knobs, bosses, or socket pieces of metal,
glass, or porcelain may be secured to the heated rods &c. either
before or after twisting. The ornamental glasswork may be applied to
gasaliers, chandeliers, lustres, pendants, stems for vases, cups, and
épergnes, and glass table ornaments generally, and also to the legs or
other portions of furniture.
