PROVISIONAL SPECIFICATION left by the said William Bowers Fitch at
the Office of the Commissioners of Patents on the 30th December 1882.
WILLIAM BOWERS FITCH of New Cross Glass Works, Deptford, in the county of
Kent, Chemist IMPROVEMENTS IN ORNAMENTING OR LETTERING ARTICLES IN
GLASS"
"
This invention relates to an improved process for producing enamelled designs,
or lettering on bottles and other articles in glass while in a hot state.
In carrying out my improvements for enamelling raised lettering or designs on
bottles the bottle with the raised letters or designs thereon is caused to pass from
the hands of the maker or blower and, while still in a heated state, under a roller
of suitable material such as asbestos, or a material covered with asbestos, such
roller being supplied with the enamelling material whereby the lettering or design
on the bottle will be coated with the enamelling material while the bottle is still
hot and the bottle being then passed as usual into the annealing furnace or oven
the enamel will be thereby completely burnt on or hardened.
When the designs or lettering are not raised I employ stencil plates so arranged
that as the heated bottle passes to the annealing furnace it passes under the stencil
plates through which the enamelling material is pressed; or suitable stamps may
be employed in place of stencil plates.
In some cases it may be found necessary to either coat the surface to be
enainelled with fluoric acid or to mix some fluoric acid with the enamelling
material

This invention relates to an improved process for producing enamelled designs,
or lettering on bottles and other articles in glass while in a hot state.
In carrying out my improvements for enamelling raised lettering or designs on
bottles the bottle with the raised letters or designs thereon is caused to pass from
the hands of the maker or blower and while still in a heated state, under a roller
of suitable material such as asbestos, or a material covered with asbestos, such
roller being supplied with the enamelling material whereby the lettering or design
on the bottle will be coated with the enamelling material while the bottle is still
hot and the bottle being then passed as usual into the annealing furnace or oven
the enamel will be thereby completely burnt on or hardened.
When the designs or lettering are not raised I employ stencil plates so arranged
that as the heated bottle passes to the annealing furnace it passes under the stencil
plates through which the enamelling material is pressed; or suitable stamps may
be employed in place of stencil plates.
In some cases it may be found necessary to either coat the surface to be
enamelled with fluoric acid or to mix some fluoric acid with the enamelling
material.
.
Having thus described my said invention and the manner of performing the
same what I claim is :-
Producing enamelled designs or lettering on bottles and other articles in glass
whilst in a heated state and before annealing substantially in the manner herein-
before described.
In Witness whereof I the said William Bowers Fitch have hereto set my
hand and seal this thirtieth day of June in the year of our Lord one
