Improvements in Apparatus for Rolling Glass.
We, ANTHONY DIXON BROGAN and ANDREW MURRAY MALLOCH sole
partners of The Glasgow Plate Glass Company, Glass Manufacturers, Firhill
Glasgow, Lanarkshire, do hereby declare the nature of this invention to be as
follows:-
:-
This invention which relates to apparatus for rolling glass has for its object the
production of such glass direct from the molten or plastic state with a smooth
surface resembling polished plate on the side which is usually roughened or
dimmed by contact with the rolling table whilst the opposite surface is either
made smooth or has a design or pattern impressed upon it by means of a pattern
roller.
The improved apparatus comprises a pair of smooth rollers on horizontal axes
one being preferably of greater diameter and at a lower level than the other so as
to form a hopper whereinto the molten or plastic glass is laid and thence carried
between the rollers by their rotation.
A third roller which is either smooth or has a pattern formed on it is fitted
at the discharge end of the apparatus and between it and a smooth travelling
plate or slab of metal the glass rolled by the first pair of rollers passes and
is carried along with the plate towards an annealing kiln into which the glass plate
is led.
The first pair of rollers in rolling out the glass cools the surface only to such an
extent as to permit of the auxiliary or pattern roller properly impressing the upper
surface whilst the under side retains the smooth surface imparted to it by the plain
roller during its contact with the smooth metallic slab or plate with which it
travels in passing under the auxiliary roller. The travelling slab or plate carrying
the glass is or may be supported by or form the top of a wheeled framing and may
be simply carried along with the moving glass plate or it may be traversed by
gearing from the gear actuating the rollers.

Improvements in Apparatus for Rolling Glass.
We, ANTHONY DIXON BROGAN and ANDREW MURRAY MALLOCH sole
partners of The Glasgow Plate Glass Company, Glass Manufacturers, Firhill,
Glasgow, Lanarkshire, 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 which relates to apparatus for rolling glass has for its object the
production of such glass direct from the molten or plastic state with a smooth
surface resembling polished plate on the side which is usually roughened or
dimmed by contact with the rolling table, whilst the opposite surface is either
made smooth or has a design or pattern impressed upon it by means of a pattern
roller.

page_text: As represented in the accompanying drawings in sectional side elevation at
Figure 1, in end elevation at Figure 2 and in plan at Figure 3 the improved
apparatus comprises a pair of smooth rollers A A¹ carried on horizontal axes in
stationary. framings H, one roller being preferably at a lower level and of the
same or of a greater diameter than the other so as to form a hopper at a whereinto
the molten or plastic glass is laid and thence carried between the rollers by their
rotation. A third roller B which is either smooth or has a pattern formed on it is
fitted at the discharge end of the apparatus and between it and a smooth travelling
plate or slab C of metal the glass rolled by the first pair of rollers A A.¹ passes and
is carried along with the plate C towards an annealing kiln into which the glass
plate is led.
The first pair of rollers A A' in rolling out the glass cools the surface only to
such an extent as to permit of the auxiliary or pattern roller B properly impressing
the upper surface whilst the under side retains the smooth surface imparted to it
by the plain roller A during its contact with the smooth metallic slab or plate C
with which it travels in passing under the auxiliary roller B. The travelling slab
or plate C carrying the glass is or may be supported by or may form the top of a
wheeled framing D and may be simply carried along with the moving glass plate
or it may be traversed from the gear E E actuating the rollers by means of
pinions F engaging the teeth of racks on the sides of the wheeled framing D or by
like means.
The glass in passing from the rollers A A¹ to the auxiliary roller B
may be guided by an inclined plate G.
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:-
1. Apparatus for rolling glass constructed combined and arranged to operate
substantially as hereinbefore described.
2. In apparatus for rolling glass the combination with a pair of smooth rollers of
an auxiliary or pattern roller and a plate or slab adapted to travel under said
roller substantially as described.
Dated this 24th day of January 1894.
