SU1844A1 - Instrument for indicating tram and railway stations - Google Patents

Description

The present invention has the I purpose to indicate the stations by means of the illuminated tape i with the corresponding inscriptions set in motion by individual motors, at which the driver must lead at stops (at the beginning of the movement to another station); in action switch or buttons .;

FIG. I shows the front view of the device, FIG. 2 is a section through AB of FIG. 1, in FIG. 3 - cut it; according to the CD of FIG. 1, in FIG. 4 is a top view of the device, without a cover; FIG. 5 - a tape and in FIG. b - wiring diagram for electrical wires and contacts; with a source of energy, electric bulbs and motors, as well as switching the motors to reverse. ;

The device (Fig. 1-3) is fixed above the front door in the car, and in the upper; The time inscribed on it is illuminated by a lamp 14 with the name of the station, and at the time of the carman a control light 13 is turned on. I The car driver has a breaker 12.

In a wooden box, tape 4 is wound on separate rollers 2 with axes 3 by separate motors (Fig. 4 and 5). The names of the stations are put on the tape.

and on it are attached contact plates 5 to 6. The operation of the device can be traced according to the scheme of FIG. 6. The purpose of the plates 5 is that, in contact with the contact rings 9 (9, 9 a) of the rollers 7 (Fig. 3 and 4) by means of the springs 9 b, 9c, include the electrical circuit of the light bulb / 5 and 14. The purpose of the plate 6 consists in contacting with the contact rings 10 (10, 10a) of the rollers 7 by means of the springs 106, 10c to drive the motors AI and / g II, which move the tape. In addition, the motors can be turned on switch 12 motorman.

When the tape is at rest (diagram of Fig. 6), the contact plates 5 are connected to the contact rings 9 of the rollers 7, and the light bulbs 13 and 14 are hot, and the latter illuminates the name of the station on the tape. At this time, the plate 6 does not touch the slip rings 10, and the motors are inactive. When starting, the driver has to turn on the motors with a knife switch 12, the tape begins to move, the plate 5 n rings 9 are opened, and the lights 13 and 14 go out, the plate 6 and rings 10 come into contact, the driver opens switch 12, but the tapes continue to move until the end of progress the plates 6, when at the last moment the plates 5 and the rings 9 are again closed, and the lamps 13 and 14 are again lit; at the same time, the tape stops, indicating the next stop.

When the car is started up in the opposite direction, the motors are reversed by switch d (Fig. 6).

SUBJECT OF THE PATENT.

A device for indicating tram and railway stations, the names of which are printed on a tape moved by individual motors, characterized by the use of

the tape (Fig. 5) of the contact plates 5, which include the light bulbs 13 and 14 in the electric circuit, in contact with the contact rings 9 (Fig. 3 and 4) of the roller 7, and the plates 6, which activate the hi and i motors, moving the tape after the message the movement of the latter by the same motors h I and h II, temporarily connected to the electric circuit by a knife switch 12 (see diagram of Fig. 6) when these plates 6 touch the contact rings 10 of the same roller 7 (Fig. 3 and 5), and the connection electrical wires and contacts with an energy source, electric bulbs and proof operation and switching the motors on return stroke is performed according to the circuit of Fig. 6
