PATENT OFFICE.

The invention relates to a station detector in which, in a known manner, a tape that winds up and down on rollers and bears the station names is triggered by a drive that is triggered electrically or mechanically when passing through a station by a stop located on the line means and moves this far that the next station name appears in front of the show opening. Since such apparatus are usually provided with a device for displaying advertisements, the same device for displaying and changing advertisements is also used.
The essence of the present invention is based on the switching of the advertising strip, which itself can be translucent or the inscription thereof can be translucent. The invention is shown on the drawing in Fig. Ι to 8, of which

Fig. Ι shows a whole car with the contact sitting on the lead wire. Fig. 2 shows the station detector from the front and
Fig. 3 seen from above in section.

In Fig. 4 the same is shown from the front with the front panel removed, while in

Fig. 5 and 6 the type of triggering of the drive and the type of entrainment of a die next to the line lying station name is shown.

7 and 8 illustrate the reversal of the belt.

In the illustrated embodiment, the station detector is provided with advertisements, which are moved in the same way as the band bearing the station names and only have a different switchover.

At each stop where a new station name is to be brought in front of the viewing opening, there is a BEZW on the line means in a known manner. Stop a to be attached to the conductor wire, which is hit by a lever b on the conductor rod next to the current collector roller as the car drives past, whereby the electric current is passed through the electromagnet which triggers the drive and which attracts the armature d. The armature d is connected directly or indirectly to the locking lever e , which emerges from one of the recesses in the locking wheel c of the drive when the armature is tightened and releases it (FIG. 6). This sets the drive in rotation and the drum / takes the tape bearing the station names with it. In order for the strip to be carried along properly, the roller, as shown, can be fitted with pins which engage in corresponding openings in the station belt so that it is guided precisely.

The distances between the sections of the ratchet wheel correspond to the size of the station names respectively. the size of the viewing opening in the housing g so that only the one name can be read. After a break

of the current, the locking lever falls into the next recess in the locking wheel.

The two take-up rollers Ji and Ji ¹ are influenced by springs, which are mounted inside the same in a known manner, which respectively are tensioned by the drive. be relaxed so that the tape is always taut. The band or the like carrying the station names is via the

ίο guide roll above located in the housing and / the advertising strip over the roller s "out. If the station tape i onto the roller Ji ¹ wound, thus reached the end of the track, the movement must / switch of the drum, so that the band i is wrapped h again to the roller switching is k through the handle;. latter is connected in the housing with the lever I and is held in the respective position by the resilient clip in, the drum or roller / in the direction of the arrow (Fig.. moving 6), so is the gear η of the engine to the wheel 0 in engagement, which in turn ρ engaged with the gear, whereby the roller / rotated (see FIG. especially Fig. 4). If now by means of the handle k at the end of Travel distance, the gear ρ is shifted, this comes out of engagement with the wheel ο and engages in the wheel η , whereby the intermediate wheel 0 is completely switched off and the roller / is moved in the opposite direction.

The tape r carrying the advertisements is attached to the spring-influenced rollers ss ¹ and passed over the roller or drum s ² . The belt is driven by the gear wheel rc ¹ , which sits firmly on the axis of the wheel η and engages either in the wheel t or in the wheel t ¹ when the belt is moved in one direction or the other.

Switching the band or the like takes place automatically, as the number of advertisements can be larger or smaller than that of the stations so that it is not affected by the switch the same can be influenced, and it is in this switching device that the present invention resides.

On the axis 11 , the bearings for the rollers ss ¹ and the associated gears tt ^{l are} placed. The tilting weight y and the arms ν v ^x are located on the u axis between the bearings. The weight is in the shown in Fig. 7 position, the tape from the roll is unrolled s ^l, i ^1, and the gear is engaged with the drive wheel 7z ¹ engaged. Gradually the tape is now wound onto the roller s ¹ , as a result of which the arms v ^{1 are} moved downwards. If the tape is approximately wound up, the tipping weight comes out of its dead center and tips over to the right, whereby the bearings, the rollers and wheels are carried along and the wheel t is thereby brought into engagement with the wheel n ^1. The tipping weight is loosely mounted on the axis u; there is a cutout in its hub, while a pin w is located on the axis u. The pin and the axle with the bearings are only taken along when the weight has passed the dead center and tips over due to its own weight. Since the wheel t is now driven by the wheel n ¹ , the tape is rewound onto the roller s. If the tape is wound onto this roller, the arms ν ν ^{1 are} moved again and the above-described process is repeated anew. Switching can also be done directly by the winding means or by a stop attached to it.

It often happens that the vehicles when driving there, because the streets are too narrow, sometimes have to drive on different roads than when driving back, in which there are also stops. In order to now also display these stops, the device shown in FIGS. 5 and 6 has been made. J on the axis or the pipes, which is influenced by a coil spring, the station names lying outside the outward line carrying belt is arranged i ^l, which is entrained i prior to the actual station name band when the respective stations, where the carriage travels through secondary roads, come. On the tape i sit the hooks i ² , which at the given time engage in openings of the tape i ¹ and when moving the drive pull it in front of the viewing opening. Once the route has been passed, the hooks are released by a stop; the tape i ^l is rewound onto the shaft by the spiral spring influencing the shaft.

The side walls of the housing are designed to be removable for inserting or removing the rollers with the strips. They are. Letters or the background made transparent so that the words can be read in the dark. For this purpose, correspondingly arranged lighting devices χ are attached behind the strips (Fig. 5 and 6).

Claims (1)

Patent claim: Station detector with an advertising tape that winds on rollers driven by a drive, characterized in that the tape is reversed by a tilting weight (y) which, after complete Winding of the tape fr) on a roller fs ¹ ) is overturned, whereby one of the gears ffJ oscillating with the tilting weight fy) , which sits on the axis of the wound roller fs ¹ ) , is out of engagement with the drive gear fn) and the other Gear ft) comes into engagement with the drive gear fn) and vice versa, for the purpose of reversing the direction of movement of the advertising tape after it has been completely wound onto a roller. For this purpose ι sheet of drawings.
