Improvements in and in connection with Advertising Placards.
1, GEORG BARTHELS, of 46, Schweinmarkt, Hamburg, Germany, Reporter, do
hereby declare the nature of the said 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 relates to the production of placard and mirror-placard apparatus,
comprising the arrangement of loose letters or other signs made of cardboard or
other suitable material of even thickness and secured in the desired positions by
pressure between a transparent front plate and a non-transparent back plate covered
with soft material. The invention is of special advantage in permitting of the
rapid production of any desired placard and of its speedy alteration at any time.
A back-ground of any desired colour may be given by covering the soft backing
with coloured tissue paper or the like.
The invention is applicable not only for the production of placards intended for
direct visual inspection, but also for such as are intended to be read by reflection in
a mirror. In the latter case, the letters are obversely placed in the frame which is
placed at a suitable angle to the mirror.
On the accompanying drawings,-Fig. 1. represents a front view of the apparatus.
Fig. 2. represents a sectional elevation of the same when closed;
and Fig. 3. repre-
sents a like view when open.
The improved apparatus consists of two frames », connected by hinges c, and
provided with fastening devices v. The frames enclose or are fitted with glass

partition 10,
of cardboard or other suitable material, which is covered with soft
fabric 3, on each side and is adapted to turn on the hinges c.
The letters or signs z, are made of cardboard or other suitable material, all of
even thickness. When arranged on one or the other side of the partition w, to form
the desired placard, they are retained in their desired relative positions by the
pressure of the opposite frame r. A chain k, serves to suspend the apparatus.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A placard apparatus characterised by two surfaces capable of being pressed
towards one another and securing loose letters or signs forming inscriptions or
advertisements capable of any alteration.
2. The combination of the apparatus indicated in Claim 1, with a reflecting
surface so arranged that the inscription or advertisement may be read indirectly.
3. The particular constructions of the apparatus indicated in Claims 1 and 2, con-
sisting of two frames r, fitted with glass plates y, and connected by hinges c, combined
with an opaque partition w, both sides of which are covered with soft fabric s, the
whole serving to accommodate changeable inscriptions or advertisements composed
of movable letters or signs, on a background of tissue paper or the like, and
when the frames are closed together to retain the letters or signs by pressure, the
arrangement providing for mirror placards by allowing the letters to be placed
obversely and the apparatus to a suitable angle to a mirror; substantially as herein-
before described with reference to the accompanying drawings.
