SU23267A1 - Device for short-circuit closure of electrical circuits - Google Patents

Description

In the present invention, the weight of a coin inserted into an automaton is used for the short-term closure of electrical circuits, which are opened after a certain period of time using a clock mechanism.

According to the device shown in the schematic drawing, when the coin is treading, a plate отт of the lever P pulled away by the spring L is deflected and clamped to the contact lever O puts the latter in contact with the contact O, as a result of which the electrical circuit is closed, The hstovik dt of the lever P is attracted by the N electromagnet included in the circuit, and the circuit remains closed until the corresponding clock mechanism opens it. After this period, the current will stop, the lights will go out, and the lever P will again turn to its original position. The clock has a circular contact K with a small gap connected to one pole of the Lj battery, the other pole L of which is sliding along the contact K

The subject is invented and.

1. A device for short-term closure of electrical circuits, driven by the weight of a coin dropped into the machine and turned off after a certain period of time by a clock mechanism, characterized in that it uses an electromagnet L, capable of keeping the circuit in a closed state until the moment its breaking by the clock mechanism, attracting the coin lever P, which closes the circuit when the coin is lowered into the machine by pressing the contact lever O, which is brought into contact with the contact O.

1. With the fixture indicated in paragraph 1 of the application, use of automatic control clocks, equipped with a circular contact nG connected to one pole of the battery and having a small discontinuity, while the other pole of the battery connects to an arrow / H sliding along the contact K.
