PROVISIONAL SPECIFICATION.
Improvements in and relating to Signs, Advertisements, Pictures,
and the like.
We, ADOLF LEISEGANG and MAX WINKELSTRÖTER both of Johannisstrasse,
Elberfeld in the German Empire, Manufacturers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to signs, advertisements, pictures and the like, which are
provided with celluloid covers or protecting plates, and which are described in
the Specification to Letters Patent No. 20197 dated the 26th day of October 1895.
The object of the present invention is to provide the celluloid cover or the like
with a metal support or backing.
A plate of sheet metal is cut to a size a little larger than the celluloid plate and
cne is laid upon the other. The required advertisement picture or the like would
of course be interposed between the two. The edges of the two plates are then
bent or returned together upon themselves, and the projecting edge of the metal
plate is finally bent over the edge of the celluloid one. The two plates are thus
held firmly together and the entrance of dust and damp is prevented. In addition
to bending the metal plate at its edges, it is preferred to slightly bend or bow it in
its length so that it acquires a greater stiffness, and, in a manner, acts as a spring
to keep the advertisement or the like firmly and evenly pressed against the
celluloid plate.

COMPLETE SPECIFICATION.
Improvements in and relating to Signs, Advertisements, Pictures,
and the like.
We, ADOLF LEISEGANG and MAX WINKELSTRÖTER, both of Johannisstrasse,
Elberfeld, in the German Empire, Manufacturers, 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 relates to signs, advertisements, pictures and the like which
ccnsist of or comprise celluloid plates or covers combined with metallic backing.or
stiffening plates.
In carrying this invention into effect the celluloid plate and the metal plate are

page_text: placed one upon the other and are secured together by bending their edges. The
required device, announcement or the like may be upon a separate sheet interposed
between them or may be formed upon either the metallic or the celluloid plate.
In order that our invention may be more readily understood we have hereto
appended a sheet of drawings to which we will hereinafter refer and which
illustrate the improved signs and mechanism which may be employed in their
construction.
Figure 1 illustrates a hand press in which the signs may be formed.
Figure 2 shows representations of a sign in the various stages of its manufacture.
Figures 3 and 4 show the die and punch of the press in different positions.
Figure 5 is an illustration in plan of the die employed.
Figure 6 is a vertical section of the die or punch which may be employed in
finishing the sign.
Referring to Figure 2 I represents a stamped out metal sheet which is afterwards
pressed to the shape shown in II. The edges are then trimmed or cut down so as
only to leave the narrow edges shown in III. The corners are now cut out as
represented in IV in order to enable the edges to be bent by illustrated by V. The
corners are now still further cut out as in VII so that the parts which have been
bent fowards the back of the plate at an angle of about 90° may be still further
bent back, while at the same time the plate may be slightly bent in its length so as
to impart greater stiffness to it. The pressing of the plate to the form shown in
I, II, III, and V of Figure 2 may be accomplished by well known means or devices
as may be the cutting of the corners in IV and VII, but the results shown
in VI and VIII are accomplished by special appliances.
Mechanism which may be conveniently employed in the manufacture of one of
the improved signs is constructed as illustrated. A is a punch or the like con-
nected to the handled screw spindle S. B is a removable sleeve or cylinder placed
upon the cylinder or socket C. Contained within B is a piston or the like D, and
within C is a sliding block E resting upon a spring F which normally tends to
press it upwards.
A celluloid plate G, Figure 3, is placed within the recess 6 formed in the top of
the sleeve B, so that when the punch A descends the plate is pressed into the form
and position shown at G¹ Figure 4. The sleeve B is now removed from and
reversed upon the part Cso that the celluloid plate now occupies the position
illustrated at G2 Figure 3.1 Both ends of the sleeve are formed alike and the
present upper end is now ready to receive another celluloid plate. The descent of
the punch A now forms the second plate as previously described and forces the
already formed plate G2 down upon the metal plate J (Figure 2, V,) which has been
placed in position upon the sliding block E. The further descent of the punch
presses the sliding block E downwards against the pressure of the spring F until
the two plates G and J enter within the part C and are bent together by the walls
or edges c as shown in Figure 4 and at VI Figure 2. As shown in the latter the
advertisement, design or the like may be interposed between the two plates, or it
may be formed upon or within either of them.
The two combined plates may be bent in the direction of their lengths so as to
hide the bent over edges behind the body of the sign and so give greater stiffness.
This may be effected by use of the press shown in Figure 6.
The
The punch or equivalent part K of the press is formed with a concave under face
or surface and is adapted to be forced downwards in any suitable manner.
anvil or die L is formed with a corresponding convex face.
The sign or the like is taken from the part C after the ascent of the ram A and
when the spring F has forced it upwards, and is placed upon the anvil L as shown
by the dotted lines Figure 6. The punch K is now forced downwards and as a
result, owing to the shape of the edges of the anvil, the sign is curved and the
edges are bent backwards as illustrated in Figure 6. The sign now has the shap
shown in VIII, Figure 2, and the cut out corners represented at VII in the same
figure are closed.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. A sign, advertisement or the like, consisting essentially of a celluloid plate
and a metallic plate joined together by bending the edges, substantially as
hereinbefore described and as illustrated by the accompanying drawings.
2. A sign, advertisement or the like, constructed and arranged substantially as
herein before described and as illustrated by the accompanying drawings.
