Patented in the German Empire on October 11, 1906.

-The invention relates to a display device for preventing money being inserted during the rewinding or addition of the sheet music of automatically playing musical instruments with any number of money insertion points remote from the musical instrument, in particular electrically operated pianos in which a perforated sheet of music in the form of a roll o

ίο the game ends automatically winds up.

The invention is characterized in that at the beginning of rewinding or at The sheet music is supplemented by an electric mechanism that effects the same Circuit closed and automatically interrupted when winding is finished ', whereby a visible or audible sign or both types of signs are attached to the given places of the money slot away from the musical instrument and also one known locking device for the coin slot brought into effect will.

25 ^ The subject of the invention is on the drawing illustrated schematically in one embodiment.

The reversing lever A belongs to one of the known systems of electric pianos, which are made to play by inserting a coin into a machine belonging to the musical instrument. The mechanism of the piano at the end of the piece automatically causes the lever A to swing around its pivot A ¹ from the position shown in full lines into the position indicated by dashed lines, with the lower end A ^{% of} this lever on the curved surface B ^{2 of} a slides along B ¹ swingable double lever B; As a result, the double lever B is transferred to the dashed position, whereupon the rewinding of the perforated sheet of music begins in a known manner. The levers A and B remain in the position indicated by dashed lines until the sheet of music is completely wound up, whereupon the levers automatically return to their original position through the winding mechanism.

According to the invention, an electrical contact plate C is arranged on the lever A , which is expediently designed to be resilient in its entirety or with its lower part; the contact piece C is followed by an electrical line c. The double lever. B carries a contact plate D to which a second line d is connected, which belongs to the same circuit as line c.

If the lever A is swung out into the position indicated by the dashed lines, the touching parts C

and D the electrical circuit is closed by lines d and c. In this circuit, an electromagnet or a device E replacing the same is switched on, which, when energized, lifts the armature F into the position shown in dashed lines. The armature forms one arm of a double lever rotatable about the pin f , the other arm F ^{1 of which has one} at its upper end ίο carries curved attachment G of any embodiment, which penetrates when the armature F is pulled by the electromagnet E into the slot guide H through which the coin is thrown into the self-cashier Z. As a result, the approach G causes the coin to be held and prevents it from falling into the self-cashier Z, which is designed in a known manner.
As soon as the levers A and B return to their original position (drawn with full lines) and thereby the circuit going through c and d is interrupted again, the armature F swings downwards as a result of its own weight or in another compulsory or non-positive manner, so that the approach G emerges from the path of the guide slot H and allows a coin located in the slot to fall into the cashier. In order to ensure that a coin is held in the slot for a short period after the circuit has been interrupted, suitable means are provided to slow down the swinging movement of the double lever F, F ¹ into the open position as much as possible; For this purpose, liquid buffers or the like can be arranged on the arms F or F ^{1 in a manner known per se.} In order to give a visible sign during the winding up of the sheet of music that the insertion of a coin into the slot H should be avoided for the time being, an opening I is provided in the wall of the machine Z , which can be filled with a transparent screen /; A suitable warning may be affixed to this screen stating that "until the lighting of this screen has ceased, money should not be thrown into the slot; the screen is illuminated by an electric lamp located inside the cashier so that the , whereas the same can be read on the screen applied words for the duration of the lighting after the cessation not conspicuously visible. to allow lighting of this screen / only during the time of winding the sheet of music, serving for lighting electric lamp K is the circuit d, c switched on, so that when the circuit is closed by the contacts C, D the lamp K is made to glow and the warning indicated on the screen / is clearly visible Umbrella / can be of the installation of the device E, F, G to prevent throwing v on coins in the guide slot. In connection with the marked visible display device or independently of the same, a special bell or other device which gives an audible signal can be provided on the self-checkout, e.g. B. in the form of an electric bell, which is switched on during the winding of the sheet of music in the circuit c, d . Instead of the visible and audible display devices described in the illustrated embodiment, similar arrangements can naturally be used; for example, instead of the screen to be alternately illuminated / a disc or the like to be brought into effect by electrical means, while the sheet of music is being wound up, it can be moved in such a way that it becomes visible with the inscription that may be attached to it, while the latter is visible after the interruption of the Stromes returns to its original position; the movement of this disc can be carried out in connection with the movement of the double hoist F, F ¹ , G , for example.
