Description

IMPERIAL

PATENT OFFICE.

The device differs from the known for use in electrical bells reaching self-breakers from the fact that the circuit spring oscillates in the Anchor is stored.

An electromagnet E with an armature A mounted in bridge B of the plate P is attached to the base plate P.

The armature A carries a two-armed lever h in a rectangular slot, the end of which is made of soft iron at its end in front of the magnet leg S, and at the opposite end of other conductive material and is resilient. This power circuit lever is held in a position parallel to armature A by a spring f.

The electrical connection screw i, which is insulated on the plate P in front of the lever h, is connected to one terminal (-), while the second terminal (-} -) is led to one end of the wire winding; the other end of the winding is conductively connected to the base plate P.

The device works as follows: A power source is connected to the two terminals (-f- and -). The spring F pulls the armature A from the pole ends SS and thereby brings the power connection lever h into contact with the power connection screw i, whereby the circuit (via + E Phi—) is established.

The electromagnet attracts the armature A lever h, and although the latter by virtue of its lower mass faster than A. The resilient end of the Stromschlufshebels h exerts a pressure on the Stromschlufsspitze i out is effected DAF a very intimate, highly conductive contact, which lasts until lever h hits a brass pin S on the electromagnet pole and, as a result of the further movement of the armature A towards the magnetic poles , is torn off from the power supply tip i , whereby the current is interrupted. The armature A is now removed from the magnet again by the spring F and the same game is repeated.

3, 4 and 5 shown in the scheme illustrate the position of the armature and of the electric circuit lever in three consecutive positions during anchor attraction.

In order to be able to utilize the armature vibrations to drive Lkufwerke etc., a pawl k is attached to the end of the extension of the armature A which goes beyond the pivot point a and engages in a ratchet wheel.

Claims (1)

Patent claim: Self-interrupting device for the operation of a ratchet mechanism, in which a longer duration of the current circuit is achieved by the fact that it is the mediator Spring is designed as a double lever rotatably mounted on the armature, which at Excitation of the electromagnet independently of the actual armature and by virtue of it less mass is attracted faster than this and, remaining in this position, the Stromschlufs maintains until the armature at the end of its pre-oscillation of the power supply tip wears off. 1 sheet of drawings.
