County of London, Manufacturer, do hereby declare the nature of this invention to.
be as follows:-
My invention refers to improvements in and relating to stamped metal advertising
letters and relates more particularly to those which are exhibited by being fixed
on the inside face of the window, so displaying what appears to be their reversed
sides.
In carrying the invention into effect, I roll two different metals into one sheet,
one side of which is furnished by one of the metals and the other side by the other
of them. In selecting the two metals, I am guided by considerations of ductility,
price and lustre. For instance, I propose to use copper for the back of the sheet
and gold or silver for the front.
The rolling of the two metals thoroughly unites them so that the backing
possesses a much more permanent and substantial face than could be imparted to it
by such superficial processes as gilding or silvering or coating with foil.
When the concave faces of letters made according to my invention are lacquered
the lustre of the metal shines through it and therefore brightens it.
Any suitable enamel or lacquer may be made use of.

COMPLETE SPECIFICATION.
Improvements in and relating to Stamped Metal Advertising
Letters.
I, CHARLES GARNIER, of 86, Farringdon Street, in the Administrative County
of London, Manufacturer, 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 :-
My invention refers to improvements in and relating to stamped metal advertising
letters, and relates more particularly to those which are exhibited by being fixed
on the inside face of the window, so displaying what appears to be their reversed
sides.
The primary object of the invention is to produce a letter which shall have a
permanently brilliant surface, and the secondary object of it is to produce such
permanently brilliant surface at much less cost than has hitherto been possible by
the methods heretofore in use.
In carrying the invention into effect I roll two or more different metals into one
sheet, one side of which is furnished by one of the metals and the other side by
another of them. In selecting the metals, I am guided by consideration of
ductility, price and lustre. For instance, I propose to use copper for the back of
the sheet and gold for the face. I always choose a metal such as gold for the face
of the compound sheet for two reasons-it is naturally brilliant and it does not
readily tarnish. Any other metal which satisfies these conditions may be used for
this purpose of the present invention.
The advantages of using a compound sheet are numerous. It is much less costly

page_text: than one of the brilliant and higher priced metal throughout. The cheaper metal
yields as strong a backing as the same thickness of the dearer metal. The facing
is much thicker than even a heavily plated surface, and moreover it is more
permanently allied to and consolidated with the backing that would be the same
quantity of deposited metal. No such process as coating with foil can pretend even
to the production of so permanent and solid a facing as my invention requires and
provides for.
The rolling of the two metals thoroughly combines them and at the same time
polishes the face, so that the hitherto necessary and subsequent processes of gilding
and polishing are dispensed with together with their attendant cost.
In order that my invention and the means by which it is to be carried into
practical effect may be thoroughly understood, I will describe it and them in
detail, referring in so doing to the accompanying figures which are to be taken as
part of this Specification and read therewith.
Fig. 1 is an elevation of an X made according to my invention.
Fig. 2 is a section taken on the line 2-2 of the previous figure and including
the glass of the window to which the letter is cemented.
Fig. 3 is a section illustrating two sheets of metal before they are combined with
each other into a single sheet by being rolled.
a is the backing, and 6 the facing metal. I have already pointed out the
considerations by which I am guided in deciding what metal I shall make use of
for the respective purposes. Either silver or gold, especially the latter, is suitable
for the facing metal because of its natural and brilliant lustre.
The letters are stamped with the brilliant facing metal on the inside, and are
intended to be cemented to the glass c of the window with this brilliant and convex
face next to it, as shown in Figure 2.
The effect of a letter made according to my invention depends therefore upon the
selection of the facing metal in point of brilliance.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The hereinbefore described process of producing a stamped metal letter for
advertising purposes by stamping a compound metal sheet with the more brilliant
metal occupying the relative position specified.
2. A stamped metal advertising letter consisting of two or more metals combined
together, the facing metal polished by the process of combination.
