PROVISIONAL SPECIFICATION.
A Process for Producing Pressed Glass Plates for Lining Walls,
Ceilings, and for similar purposes.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Max Hoffmann of Bernsdorf, Germany, Manufacturer, to
be as follows:
==
The object of this invention is to produce pressed glass plates of any strength and
size adapted to be used for lining walls, ceilings and the like.
Hitherto plates of blown glass have been used for the purposes above described.
These plates having a smooth surface and being provided with pasted and coloured
or burnt in patterns were disadvantageous, in that they offered no sufficient
resistance and could only be produced of slight strength. For the purpose of
fastening these plates to the wall, ceiling &c., they were partly roughed or small
pieces of glass were burnt upon the back of the glass with a flux,
The object of this invention is to overcome these disadvantages. For this
purpose a glass press is used, the matrix of which is provided with patterns
corresponding with the surface of the glass whereby the front face of the plate is
pressed. The press however is provided with recesses so as to produce on the back
of the plate ribs or pins of any suitable form whereby a durable connection between
the glass plate and the cement may be made.
The plates may also be bevelled or rounded at the corners, that they can be
easily fixed to the wall or ceiling by means of screws.
Dated this 21st day of May 1894.

COMPLETE SPECIFICATION.
A Process for Producing Pressed Glass Plates for Lining Walls,
Ceilings, and for similar purposes.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Max Hoffmann of Bernsdorf, Germany, Manufacturer,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-.
This invention has for its object the manufacture of glass plates for covering
walls, ceilings, and the like so made that the plates are on the front surface
provided with embossed designs and on the back surface with ribs or protuberances
which will form a durable junction between the glass plate and the cement with
which the finished plates are secured to the wall, ceiling and the like.
In the accompanying drawings

page_text: The apparatus consists chiefly of a matrix "a" which is fastened on the table of
a glass press. This matrix is, as shewn in Figure 2, furnished on its surface with
designs, by means of which the front surface of the glass plate receives the desired
pattern.
2
The male part 6 which is secured to the press spindle by means of a pin or peg o
or other suitable means is provided on its lower surface with hollows or indentations
(see Figure 1) so that the back surface of the plate receives cross ribs pegs or
protuberances of any shape which will afford a durable junction between the glass
plate and the cement.
Of course the hollows or indentations may be in the matrix and the pattern in the
male part of the press.
The finished plate is shewn in Figure 4 from which it will be seen that the plate
is, on its front surface, provided with embossed designs according to Figure 2 whilst
the back surface has ribs or protuberances as shewn in Figure 3.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A process for the manufacture of glass plates for covering walls, ceilings.and
the like consisting in the employment of pressure on the plates in such a way that
they have a front surface with embossed designs and at the same time a back
surface with ribs or protuberances produced substantially in the manner herein
described.
2. An apparatus for the manufacture of glass plates such as are referred to in the
preceeding claim consisting of a matrix a which may contain the pattern or
the hollows, and a male part which may contain the hollows or the pattern to be
used in a press substantially as herein described and shewn in Figures 1 to 3 of the
accompanying drawings.
3. A glass plate which is provided with embossed designs on the front surface
and with ribs or protuberances on the back surface substantially as described.
Dated this 23rd July 1894.
