Improvements in Means for Producing Alternating Advertisement
Pictures in Automatio (Coin-freed) Apparatus.
I, BOGUMIL VON SZCZAWINSKI, of 48 Chausse Strasse, Berlin, N., Germany,
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 :-
This invention relates to improvements in means for producing alternating
advertisement pictures in automatic (coin-freed) apparatus and has for its object
the bringing of advertisement pictures, writings, printed matter and the like
before the windows, or doors provided with windows, of automatic (coin-freed)
apparatus, said apparatus being set in motion either directly by the introduction of
a coin or, in the known manner, by the pulling out of a handle after the intro-
duction of a coin. In the first case, the cylinders, rollers or pulleys around which
an endless band bearing the different advertisement pictures is placed, are set in
motion (upon the handle being pulled out), by means of a bent lever, and are
stopped again when the handle returns to its position of rest, whilst in the second
case the cylinders, rollers or pulleys are set in motion through the pulling out of
the handle, by means of tooth wheels, the return of the handle to its former position,
however, producing no effect.
The advantages which the present apparatus shows as compared with known
apparatus of a similar kind lie specially in simplicity of construction and the
certainty of action.
In the arrangement and details shewn by the accompanying drawings
Figs. 1 and 1 represent the advertising apparatus, with driving mechanism and
releasing contrivance in vertical section, whilst
Figs. 2 and 3 are details shewing direct action by means of the tooth rack.
Over the rollers r, r (Fig. 14) the upper of which is adjustable and provided
with driving mechanisın, runs the endless band and on this are the advertisement
pictures, inscriptions, announcements, and the like, which, upon the periodical
rotation of the cylinders r r are carried in turn past the windows g in the door of
the apparatus.
For releasing the upper roller which is provided with driving mechanism and
furnished on its periphery with a projection, a cranked lever c³ is arranged so
as to oscillate on the pivot c. This cranked lever crests, with the projection
at the end of its upper arm, on the periphery of the roller r, and with the end of
its downward diverted arm on the rod h provided with a projection. If the
rod, for the purpose of removing the goods, be drawn out by pulling the knob h¹
the projection causes a motion of the crank lever of such a kind that the
projection of the upper arm releases the roller and allows it to turn together
with the endless band 7 by means of the clock work in the direction of the arrow
until the crank lever returns and effects an arrest of the roller r. The roller'r
is so measured or controlled that the endless band is always moved only as far as
the distance from one of the windows g to the other.
In the details represented in Figs. 1, 2 and 3, if the rod h, which is provided
with a handle as well as with teeth, be drawn in the direction of the arrow x
the tooth wheel b engaging therewith, but revolving loosely on the shaft of the
lower roller r, is moved in the direction of the arrow y (Figs. 1 and 2). On the

page_text: front side of the tooth wheel b is a pawl c which is controlled by'a spring. This
pawl engages with a second tooth wheel d firmly fixed on the axle of the
lower roller r, so that said wheel takes part in the movement. In consequence of
this, the rollers rr are set in rotation and the endless band with the pictures is
drawn past the windows gg.
In order that the rod h when released and moving inwards in consequence of
the action of the spring e may not carry the endless band / bearing the advertise-
ments &c. backwards in the contrary direction to that of the arrow za pawl f,
engaging with the teeth of the tooth wheel d is fixed in the inside of the casing
of the apparatus (Fig. 3) under the tooth wheel d which is firmly fixed on the
shaft . The tooth wheel d and the roller shaft rare thus held fast when the
rod moves inwards, whilst the tooth wheel seated loosely on the shaft can
take part in the inward movement of the rod A without any misplacing of the
endless band L.
If now the rod à be again drawn out after a coin has been introduced through
the slot, the endless band is moved the prescribed distance in the direction
of the arrow and fresh pictures appear before the windows g of the door t.
Fig. 4 shews a further improvement in this invention in which the crank
levere controlling the roller with the advertisement pictures is réplaced by a
simple lever which, upon the rod & being pulled out for the purpose of
removing the articles for sale, comes in contact with a plate a and by producing a
completion of the circuit in an electric current, effects the operation of the roller
bearing the advertisement pictures, in the manner described.
A wire a leads from the elements or accumulators a direct to the electromotor E
and a second wire a to the contact plate z.
The lever e, in this instance a one arm lever, is moveably attached to the fixed
point and lies with its other end free on the rod h, which is pulled out of the
case or holder in the usual way after the introduction of a coin. A third wire a³
leads also from the pivote of the lever c' to the electromotor. As soon as the
rod is pulled out for the purpose of removing articles, the free end of the lever e
falls on to the contact plate so that a current is produced. The electromotor
also comes into operation and affects the roller with the advertisement band causing
it to revolve a certain distance.
Upon the rod A being net free; the rod moves inwards by the action of a
spring e, removes the lever et from the contact plate b, and, the current, being
thus interrupted, the roller with the advertisement band is brought to a standstill."
In Figs 6, 6, 7, and 8, another modification of this invention is shewn, in' which
the bent levere (Fig. 14) which alternately arrests and releases the roller is
not actuated by the drawing out of the rod A but by a sliding plate, upon the
introduction of a coin.
In these views is shewn a metal plate K which is firmly attached to the rear
side of the front wall 'of the case or holder. On this plate a second smaller plate
or slide m is moveably secured in slots K'.
Behind each of the incisions for introducing the 'coins (that is to say, 'on the
inside of the automatic apparatus) is arranged a pusher n which is moveable 'in
an upward direction in slots, so that, upon the introduction of a coin, the pusher
is raised. In order to effect this the pusher is bent as shewn in Fig. 7. On
the plate'm is a pin o which rests against the oblique surface n of the pusher 'n.
Now, as soon as a coin (no matter through 'which of the incisions) is introduced,
one of the pushers a will be 'raised 'and press 'with its oblique 'surface against
the 'pin o'and-push the latter, together with the plate m in 'the directed indicated
by the arrow. This side movement of the plate or of the pusher m'causes 'the
one end (p) which is formed as a wedge for the purpose, to press bénéath'the bine
arim of the bent lever q and to raise this 'a "certain distance (Fig. 8). The
other arm of this lever is furnished with a projection q', by means of which it
engages with a projection of a wheel seated on the 'shaft of a clock-work
arrangement and thereby arrests the wheel. By the upward movement, however,

page_text: of the one arm, the arm of the bent lever which is furnished with a projection
will be somewhat lowered and will release the roller r that is actuated by the
clock-work arrangement, so that the roller can now rotate. The plate or the
pusher m is meanwhile drawn back again through the operation of a spring vand
the bent lever returns to its former position and arrests the roller r again. On
another shaft of the clock-work arrangement the roller is seated and over this
the band bearing the advertisements is led, which in this way can be shifted the
distance of one window g to another.
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:
