PROVISIONAL SPECIFICATION.
Improved Apparatus for Imparting Surface Ornamentation to Glass.
We ANTHONY DIXON BROGAN, and ANDREW MURRAY MALLOCH, both of Firhill,
Glasgow, in the County of Lanark, Glass Manufacturers, do hereby declare the nature
of this Invention to be as follows :-
This invention relates to improved apparatus for imparting to glass sheets or
plates surface ornamentation such as patterns or designs in intaglio and relievo, the
said ornamentation being under the invention imparted in the act of transferring the
glass from the flattening or heating kiln to the annealing kiln or leer by running
the wagon carrying the glass under an impressing roller or rollers with which the
glass comes in contact.
The impressing roller is fitted adjustably in bearings preferably within the mouth of
the annealing kiln or leer so that it may not be subjected to the high temperature of
the hot kiln and when after the glass has been flattened in the process of manufacture
or re-heated after having been manufactured the carriage or table bearing the sheet
or plate is being transferred from the flattening or heating kiln or leer the said
roller bears upon the surface of the glass which is impressed with the pattern or
design on it.

COMPLETE SPECIFICATION.
Improved Apparatus for Imparting Surface Ornamentation to Glass.
We, ANTHONY DIXON BROGAN and ANDREW MURRAY MALLOCH both of Firhill,
Glasgow, in the County of Lanark, Glass Manufacturers, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This Invention relates to apparatus for imparting to glass sheets or plates surface
ornamentation such as patterns or designs in intaglio or relievo, the said ornamentation
being under the invention imparted in the act of transferring the glass from the
flattening or heating kiln to the annealing kiln or lear by running the wagon carrying
the glass under an impressing roller or rollers with which the glass comes in
contact.
The impressing roller or rollers is or are fitted adjustably in bearings preferably
within the mouth of the annealing kiln or lear so that it may not be subjected to
the high temperature of the hot kiln and when the glass has been flattened in the
process of manufacture or reheated after having been manufactured the carriage or
table bearing the sheet or plate is transferred from the flattening or heating kiln to
the lear and passed under the said roller so that the latter bears upon the surface of
the glass and impresses the pattern or design on it.
In the accompanying drawings figure 1 is a longitudinal vertical section, figure 2
a horizontal section and figure an end elevation of a heating kiln and lear showing
our invention applied thereto. Into the heating kiln A which is separated from the
lear or annealing kiln B by a depending bridge C the glass plate or sheet d is carried
by the wagon D and is brought to or maintained at the desired temperature-The
wagon is thereafter run into the lear or annealing kiln B and in its passage from the
one chamber to the other the glass plate or sheet is traversed under and in contact

page_text: with a roller E on which is engraved or otherwise formed the ornamental design or
pattern to be imparted to the surface of the glass the said roller being carried in
bearing brackets behind the bridge C.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The arrangement of apparatus for imparting surface ornamentation to glass
substantially as described with reference to the annexed drawings.
