PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Price or Descriptive
Window-tickets.
I, DAVID WILLIAM WALL, of 2 Camberwell Gate in the County of Surrey,
Hatter, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in the manufacture of price or descriptive
window tickets has for its object to produce metallic window tickets cheaply by a
purely mechanical process without the aid of skilled labour, and consists essentially
in etching the metal plates by means of a sand blast certain parts being protected.
by a stencil in the usual manner.
In manufacturing a window ticket according to this invention the body of the
metal plate to be etched is made of brass or nickel or other suitable metal and is
plated with copper or silver or other metal and its plated surface is polished and
covered with a suitable stencil representing the price or description of the article
to which the ticket is to he applied. The protected plate is then subjected to the
action of the sand blast which may be continued until it has removed the whole
thickness of the plating except at the protected parts which remain untouched, or
it may be arranged only to etch the plating.
.
Instead of one plating two platings may be given and a second stencil applied to
the plate after the sand blast has removed the whole thickness of the last plating
at the unprotected parts and be again subjected to the sand blast to remove the
first plating at parts unprotected by the second stencil.
In a similar manner three or more platings may be applied to the plate and
removed at the desired parts.
Dated this 30th day of October 1893.

Improvements in the Manufacture of Price or Descriptive
Window-tickets.
I DAVID WILLIAM WALL, of 2 Camberwell Gate, in the County of Surrey,
Hatter, 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 for improvements in the manufacture of price or descriptive
window tickets has for its object to produce metallic advertising tablets or tickets
cheaply by a purely mechanical process without the aid of skilled labour and
consists essentially in etching the metal plates by means of a sand blast certain
parts being protected by a stencil in the usual manner.
In manufacturing a tablet or ticket according to this invention the body of
the metal plate to be etched is made of brass or nickel or other suitable metal
and is plated with copper or silver or other metal and its plated surface is polished
and covered with a suitable stencil representing the price or description of the
article to be sold or to which the ticket is to be applied. The protected plate
is then subjected to the action of the sand blast which may be continued until it

which remain untouched or it may be arranged only to etch the plating.
Instead of one plating two platings may be given and a second stencil applied
to the plate after the sand blast has removed the whole thickness of the last plating
at the unprotected parts and be again subjected to the sand blast to remove the
first plating at parts unprotected by the second stencil.
In a similar manner three or more platings may be applied to the plate and
removed at the desired parts.
In a further modification, a suitably polished metal surface is etched as above
described and then before the template is removed an inking roller carrying a
suitable colour is run over the plate and fills in the etched part with ink leaving a
frostéd margin giving effect to the tablet or ticket between the polished part and
the colour the raised edges of the template preventing the ink being deposited at
this place.
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 :-
The process for manufacturing advertising tablets and descriptive window tickets
consisting in etching metal plates by means of a sand blast substantially as
described.
