PROVISIONAL SPECIFICATION.
A Novel Means of Producing Glass Tablets or Inscription Plates
and in Preserving the same from Climatic Injury.
CLEMENT JAMES BUTLER of 14 Garrick Street, Covent Garden, Middlesex,
Stained Glass Draughtsman do hereby declare the nature of my said invention to be
as follows:-
This invention has for object the manufacture of glass tablets or inscription plates
in a novel and permanent manner particularly tablets or inscription plates for
indicating the Donors of Ecclesiastical Windows Companys Halls, and other places
such as Wall or Mural Tablets the process constituting a staining action of the glass
at the back only.
The second object is to preserve Tablets so manufactured from climatic injury and
damp without losing their brilliancy or surface appearance whereby the inscription
can be read.
According to the usual practice brass or like metal plates are employed as tablets
and notwithstanding the lacquer or varnish put upon the same, the surfaces from
climatic action or from condensation or other causes become rapidly tarnished and
great difficulty is experienced in reading the inscription.
Now by my invention the inscription is always discernable and is not liable to
suffer from the action of the weather, dampness or other injurious influences.
For the purpose of my invention I paint, write or print on one surface of a sheet of
glass, with Glass Stainers paint, the desired inscription, ornamentation, bordering or
other, either as a ground work or as the inscription proper. If I paint with Glass
Stainers paint the inscription first I may do it in a comparatively light tone of colour
and after firing the same to fix the paint as a surface staining 1 may coat the
other parts of the glass, or all over the glass with Glass Stainers paint of a
deeper tone of colour and then again fire the plate for fixing the colour as surface
staining so that the glass thus prepared would have the inscription of a brighter
hue than that which might be termed a backing, or the inscription or the backing may
be of Glass Stainers paint only and the other part after the firing can have a layer or
coating of any plaster or cement adhered to it; for instance if the inscription on the
tablet be in chocolate or a brown colour, the other parts of the tablet by the cement
would have a white, blue or other coloured backing, or the reverse of this may take
place; i.e. the ground body or backing may be from Glass Stainers paint and the
inscription in cement or plaster of white or other colour, or other means may be
adopted to form a backing so that the fired Glass Stainers paint appears as part of
same through to the front.
Tablets thus far prepared may be employed in any ornamental manner or as
direction tablets such as Street names or as other indicative tablets. These may be
put into frames and when used for Mural purposes and exposed to climatic dampness
or other injurious influences I float the back of the sheet of glass, prepared with the
Glass Stainers paint preferably in two tones of colour and fired as hereinbefore
described, with plaster after setting it i.e. the plate in a marble or other stone frame
which will close up the edges of the glass tablet as well as the back. I then with a
sheet of slate to the size of the opening in the back of the stone frame confine the
glass against all action of atmosphere or damp, or heat.
This slate backing I prefer to key to the stone frame and also the joints of the stone
itself using plaster or a cement to assist the keying operation and make it of a
permanent character.

page_text: I have referred to stone for frames and to slate for backing, but they may be of
metal and other material according to circumstances.

COMPLETE SPECIFICATION.
A Novel Means of Producing Glass Tablets or Inscription Plates
and in Preserving the same from Climatic Injury.
I, CLEMENT JAMES BUTLER, of 14 Garrick Street, Covent Garden, Middlesex,
Stained Glass Draughtsman, 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 has for object, the manufacture of glass tablets or inscription plates
in a novel and permanent manner, particularly tablets or inscription plates for
indicating the Donors of Ecclesiastical Windows, Company's Halls, and other places,
such as Wall or Mural Tablets, the process constituting a staining action of the glass
at the back only.
The second object is to preserve Tablets, so manufactured, from climatic injury and
damp without losing their brilliancy or surface appearance, whereby the inscription
can be read.
According to the usual practice brass, or like metal plates are employed as tablets
and notwithstanding the lacquer or varnish put upon the same, the surfaces from
climatic action or from condensation, or other causes become rapidly tarnished and
great difficulty is experienced in reading the inscription.
Now by my invention, the inscription is always discernable and is not liable to
suffer from the action of the weather, dampness, or other injurious influences.
For the purpose of my invention, I paint, write, or print on one surface of a sheet
of glass, with glass Stainers paint, the desired inscription, ornamentation, bordering,
or other, either as a groundwork, or as the inscription proper. If I paint with glass
Stainers paint, the inscription first, I may do it in a comparatively light tone of
colour and after firing the same to fix the paint as a surface staining I may coat
the other parts of the glass, or all over the glass with glass Stainers paint or stain of
a deeper tone of colour and then again fire the plate for fixing the colour as surface
staining, so that the glass thus prepared would have the inscription of a brighter hue
than that which might be termed a backing, or the inscription, or the backing may be
of glass Stainers paint only and the other part after the firing can have a layer or
coating of any plaster or cement adhered to it, for instance, if the inscription on the
Tablet be in Chocolate, or a Brown colour, the other parts of the Tablet by the cement
would have a White, Blue, or other coloured backing, or the reverse of this may take
place .e. the ground body or backing may be from glass Stainers paint and the
inscription in cement, or plaster of White, or other colour, or other means may be
adopted to form a backing, so that the fired glass Stainers paint appears as part of
same through to the front.
Tablets thus far prepared may be employed in any ornamental manner, or as
direction Tablets, such as Street names, or as other indicative Tablets. These may be
put into frames and when used for Mural purposes and exposed to climatic dampness,
or other injurious influences, I float the back of the sheet of glass prepared with the
glass Stainers paint preferably in two tones of colour and fired as hereinbefore
described with plaster after setting it i.e. the plate in a Marble, or other suitable frame
which will close up the edges of the glass Tablet as well as the back. I then with a
sheet of Slate, or Marble to the size of the opening in the back of the stone frame,
or larger than the opening to form a slab, or backing for the frame, confine the glass
against all action of atmosphere, or damp, or heat.

page_text: "
This Slate or Marble backing, I prefer to "key" to the stone frame and also the
joints of the stone itself, using plaster, or a cement, or putty to assist the " 'keying
operation and make it of a permanent character.
I have referred to stone for frames and to Slate for backing but they may be
of metal and other material, according to circumstances.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The novel manner, or method of preparing glass Tablets (Mural and other), also
inscription plates for inside and for outside uses, and the means or method of protecting
them from climatic injury, as above described.
