PROVISIONAL SPECIFICATION.
A Method of Making Rolled Glass and Appliances therefor.
JOHN ARMSTRONG, C.E. 11 Queen Victoria Street London, E.C. do hereby declare
the nature of this invention to be as follows
The object of this invention is to produce certain effects on rolled glass which will
be similar to blown glass, and also for the purpose of producing patterns on
rolled glass.
Antique Cathedral, Venetian or other fancy glass which has a peculiarity of a
variety of thickness throughout is produced by blowing.
This I accomplish by having a roller or rollers and a table if done by means of
rollers, two are used and their surfaces are made of unequal heights, so that there is
undulations or indentations on their surfaces which when the glass is passed between
them produces the appearance necessary.
If produced on a table, the roller and the table are made with undulations on their
surfaces, or only one may have it.
The method of making a pattern or devices is by getting a number of blocks cut,
engraved and fitted on to the roller or table and fixed by means of screws, or other
attachments and which may be altered and a new or a variety of patterns produced,
type or letters may be conveniently arranged for printing devices &c., on glass opal
or other substance and which may be filled up with colour before or afterwards.
The method adopted for giving a polish to the surface of the glass is by using
rollers of a non-oxidising material and highly polished the table may be made of the
same and used as hot as possible.

COMPLETE SPECIFICATION.
A Method of Making Rolled Glass and Appliances therefor.
I, JOHN ARMSTRONG, of 11 Queen Victoria Street, in the city of London, Civil
Engineer, 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 the manufacture of fancy rolled glass, opal, and the like
and to apparatus or appliances therefor.
Antique, Cathedral, Venetian and other kinds of fancy glass which possess the
peculiarity of varying thickness have hitherto been produced by blowing.
My invention has for its object to produce a similar effect and also patterns or
devices in rolled glass.
For making antique, Cathedral, and Venetian glass by rolling 1 make use of a
roller and a table or of a pair of rollers, the table or the rollers being made with an
undulating surface so that when the glass is rolled between them it shall be of unequal
thickness and shall resemble blown, antique or Venetian glass.
When it is desired to produce patterns on one or both sides of my rolled fancy
glass I employ blocks with the required pattern cut upon them. Where a running
pattern is required or a pattern that is repeated, only one block need be cut, the
other blocks being made therefrom by means of a die from which they can be
stamped or cast. These blocks are then set up on a roller or a table and fastened
thereto by means of wedges, bolts, screws, or other suitable fastenings, or they may
be put on the roller in rings. The blocks are made in a similar manner to printing

and with perfect fitting joints so that there will be no spaces left in their
surface.
The glass, opal, and the like, produced by this process with type &c. may have
colour or coloured glass or enamel inserted in the parts where they are printed. This
is done while the glass is still hot, whereby the colour or other material becomes fused
in the substance of the glass.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. The manufacture of rolled, antique or Venetian glass, opal or the like, by
the employment of rollers, or of a table and a roller, made with undulations on their
surfaces for the purpose of producing a varying thickness of the glass to imitate
blown, antique or Venetian glass substantially as described.
2. Producing patterns or devices upon one or both sides of sheets of rolled glass
by the employment of blocks having the pattern on them, the said blocks being
arranged substantially as hereinbefore described.
3. Producing coloured or enamelled letters or patterns upon rolled glass by filling
in the impressed letters or patterns with colour, coloured glass or enamel substantially
. as described.
