PATENT OFFICE.

The purpose of the present invention is to automatically display the stations and stops on railways and trams. The same can also be used for advertising purposes during the journey between the stations.

In the accompanying drawing, the station indicator is shown in FIGS. 1, 2 and 4 in different projections shown, while Fig. 3 shows the circuit of the electrical Control shows.

A band, the width of which is determined by the dimension α (Fig. 1) and the length of which depends on the number of stations and advertisements, is thereby divided in its longitudinal direction into equal parts, each equal to the dimension b (Fig. 4) that a metal wire of good electrical conductivity is knitted perpendicular to the longitudinal direction of the tape each time. This results in metal strips approximately 1 mm wide on the surface of the tape at equal intervals. The fields between them are alternated with the name of a station

or printed with an advertisement. :

As can be seen from FIG. 4, the band prepared in this way is fastened and wound up on the shaft c , from there guided over the guide shafts d and e past the viewing hole b to the shaft f , on which it is also fastened.

An engine with a strong spring seated on the shaft g (FIG. 1) transmits the movement through two bevel gears to the vertical shaft h ; on the same a hollow shaft i is displaceably arranged, which is securely carried along by a pin of the shaft h which protrudes into a slot in the hollow shaft i. At the two ends of the hollow shaft i there is a bevel gear, of which either the upper or lower bevel gear is in engagement with the corresponding small bevel gear of the shafts c or /, so that either the shaft c or the shaft f in the is driven by the direction of rotation indicated by arrows. The hollow shaft i has two collars in the middle (FIG. 2), between which the reversing lever k (FIG. 1) engages, so that the hollow shaft i can be brought into the desired position by hand and can be determined there. The large gear wheel sitting on the shaft g also sets (FIG. 1) a shaft in rotation on which the ratchet wheel Z is located; at the same time the wind vane m is moved by means of repeated translation by this wave, which is used in a known manner to regulate the speed of the engine. The lever η , which is rotatable about its center in the indicated arrow directions, can intervene in the ratchet wheel / and thus bring the engine to a standstill. The lever η is influenced by the electromagnet 0, which rotates the lever through its magnetic effect and thereby releases the jamming wheel. If the electromagnet 0 has attracted the lever η , the lever ρ (Fig. 4), which can be ^{rotated about its 1} lower end in the indicated arrow directions, is placed over the left end of the same. This lever ρ is adjusted by the electromagnet q so

influences that the lever η is released again as soon as the lever ρ is attracted by the electromagnet q. Against the upper guide shaft e are two current circuit springs r (Fig. I), through the connection, as can be seen from the circuit diagram Fig. 3, a current is closed, which excites the electromagnet q. The circuit is at the circuit springs ίο usually interrupted, since the display tape is located between the same and the shaft e , while if one of the metal strips worked into the tape touches the circuit springs r, the current is closed. This electrical connection also causes the electric bell s to sound. The electromagnet 0 is excited by the same power source, but by a special line (Fig. 3), the current connection ends t can be closed either automatically by means of a route stop or by hand. With automatic closure z. B. in trams the current connection ends on the pantograph arm on the car and are closed at the top by an attached to the holding wires of the overhead line next to this power connector for a short time. . The device works as follows: If the current is closed for a short time (while driving) at t (Fig. 3), the electromagnet ο is temporarily excited and pulls the lever η on. As soon as it touches the electromagnet ο, the lever ρ engages over the left end of the lever η and holds it in this position. This triggers the engine and the display tape moves from bottom to top when the bevel gears are shifted as shown in the drawing. If this movement has now progressed so far that one of the metal strips worked into the display strip touches the two current circuit springs r , the circuit in which the electromagnet q is located is thereby closed and the lever ρ is therefore pulled. As a result, however, the lever η is released so that it engages in the ratchet wheel / and brings the engine to a standstill. With a new current supply for the electromagnet 0, the same game would be repeated. If the route stops were placed next to the overhead line in such a way that there is one just before a stop and just behind it, an advertisement would be read during the journey between the stops, while the name of the stop would appear just before the stop and when leaving the stop gives way to an advertisement again. Both the appearance of the name of a stop and the appearance of an advertisement would be indicated by the ringing of the bell. On the return trip, by changing the control lever k (Fig. 1), the shaft c would be driven and the display tape would move in the opposite direction. PateNT-AνSPRUcη: A station indicator in which the display tape, which unwinds and winds up over two rollers, is moved by an engine which is triggered electrically by means of a line stop and automatically comes to a standstill, characterized in that metal strips worked into the display tape close a circuit through which an electromagnet (q) is excited, which pulls a lever (p) , thereby releasing a locking lever (n) and thus brings the engine to a standstill. 1 sheet of drawings.
