SU22741A1 - Coin Automat for automatic telephone exchanges - Google Patents

Description

The present invention relates to the device of a coin machine for automatic telephone exchanges, the principle of which is to shunt or turn off the microphone with a time counter, simultaneously serving to control the duration of a call. As a time counter, the usual 3–5 minute clocks can be used, mounted either in the case of a conventional apparatus, or from outside to an automatic telephone set.

In FIG. 1 shows the proposed coin-laundered coin dispenser; FIG. 2 and 3 - details of its device.

The operation of the machine is as follows: the handset is lifted and the coin is lowered into the hole 1. If the coin of the required value, then in its way it will touch the lever 2 (Fig. 1 and 2), which will drop by the contact dog 3, the closing line of the device. After that, the required number is dialed. When the called subscriber answers, button 4 is pressed, which is connected with the delivery plate 5. This plate presses on the manet, and the movement is transmitted to the second mobile plate B, which has a pin abutting the clockwork

sector of clockwork. In this way, the clock mechanism turns on and off the microphone shunt. When the button moves, the coin moves to the piggy bank channel and falls into it when the button 4 is released. A double shunt or a double shutdown is applied to the microphone. The first shunt is opened with the help of the winding sector, equipped with a protruding pin, which in its extreme positions acts on the contact arm 8. The microphone shunt is opened only when the watch mechanism is fully wound. In the case of the inclusion of a sector pin with full winding of the clock mechanism will drop over the spring of the striker and turn on the microphone in line. The second shunt is arranged on the plate 5 and turns off only after it is released, at which time the clock mechanism is also set in motion. After 2/2 minutes, a call should be heard warning of the end of the conversation, and after 3 minutes the pin of the sector of the clock mechanism will press the beam that will turn on the microphone shunt, or the hammer spring will turn off the microphone. Upon the return of the sector back to the contact dog 3 under the action of the impact of the striker 9 (Fig. 1, 2 and 3) deviates to the side, the lever 2 will jump off and thus break the line. This is intended to exclude the possibility of continuing to listen, and then, regardless of whether the handset is hung up or not, the line connectors will return to a quiescent position and thereby switch off the current from all devices in this line. The movable plate 6 returns to its original position only after the pin of the plate 5 presses the cam 10, i.e. by lowering button 4. A coin that is not held by the plates of the plates falls into the piggy bank 13. If the subscriber is busy, the microtelephone is hung up without pressing the button, and the platform connected to the lever retards, releasing the through channel 12, and come back. Hole 1 is made exactly along the diameter of the coin, so that a larger coin cannot enter the hole; For screening out coins of smaller diameter, a conventional filter is applied through the tray system, which has a regulating screw that causes a smaller diameter coin to fall into the through channel, lever 2 min. It is possible to start the clock mechanism with a lever rather than a button. In this case, the handset is picked up and the desired number is dialed. If the subscriber is free, the coin is lowered into the hole 1, which will free the watch when it falls. The microphone shunt is broken and the caller can talk. After three minutes the microphone shunt

must be turned on again, and the line of the apparatus will be broken for an instant.

The subject matter of the invention.

Claims (5)

1. A coin machine for automatic telephone exchanges, characterized by the use of a time counter located at the subscriber, which, when the button is pressed, pushes the microphone for a certain period of time and, thus, determines the duration of the conversation, after which the circuit of the whole device is automatically turned off. 2. At the automaton of claim 1, the application, in addition to the main shunt, is an auxiliary, shunting microphone when pressing the counter button and having the function to prevent the conversation from being pushed. 3. In the machine according to claim 1, use on the coin tray an opening intended for screening out coins having a diameter smaller than that required. 4. Automatic change of machine according to p. 1,2, 3, characterized in that not the button is used to start the time counter, but the weight of the coin acting on the time counter previously inserted into the circuit when the microtelephone is removed. 5. On the machine according to claim 1, use a contact lever, actuated by the weight of the coin and used to turn on the device line.
