To solve the problem, a current automatically in certain interspaces to send in a line to through the movement required to interrupt the current or to perform any kind of mechanical work through the electricity itself, according to D. R. P. 54052 is the Device met that by the tightening of an anchor one located on a disc Pin pushed away, and so the disc is given a drive, its living power continues until the pin after a time determined by the action of a tension spring comes back to rest on the anchor.

With the present invention of an "electric timepiece" the task mentioned is supposed to be practiced in a completely different way be solved by interrupting a temporarily current-closing mercury contact an electromagnet is ineffective, causing a lever movement as a result of which another mercury contact that had existed up to that point was initially also interrupted, but after a certain period of time caused by the outflow of a Amount of mercury and a related rise in a mercury level can be determined is restored.

The following arrangement is made for this purpose:

The communicating tubes Q ¹ and R are filled with mercury, as is the individual tubular vessel Q ² .

In Q. ¹ and Q ^2, the shells G ¹ and G ^2, made of a resistant against the influence of the contact with mercury material, by means of the bars S ¹ and B ^'2 on the arms H ¹ and H ² dunk, a are suspended in S stationary double lever.

The bowl G ¹ , with a narrow opening at the bottom, dips a little into the mercury mass of Q. ¹ when the apparatus is in the rest position; but it can also hover a little above the mercury.

The bowl G ² , with a wide outflow opening at the bottom, dips below the surface of the mercury in Q ² when the device is not switched on.

In R , a regulating screw Z dips into the mercury located there.

If a current coming from the current source T is now closed by the switch U , it goes over the stand S, arm H ² , rod -B ² , which is metallic from above up to the line X , over the wire D armored with platinum at the bottom, which reaches into the middle of the wide outflow opening of G ' ² , through the mercury in Q ² to wire V, via electromagnet E to wire W, and through the mercury in R via regulating screw Z back to the battery.

Arm H ¹ is attracted to E by means of anchors ο, shell G * is so deeply immersed in the mercury of Q. ¹ that it fills up. Bowl G ² is pulled out of the mercury from Q ² so high that it drains off quickly through the wide outflow opening, whereby by means of the wire D, which, by the way, can fill the outflow opening even more by means of a disc or other widening to be attached, the existing one

Current flow is maintained for a brief moment by the mercury ^{beam while shell G 2} rises.

As soon as the current is interrupted by the cessation of the mercury ^{outflow from G 2} , arm H ¹ goes up, due to the action of the projection L serving as an overweight load, the stop of which can be regulated by screw M. The filled bowl G ¹ is lifted completely (or partially) out of the mercury in Q. ¹ , so that the previous level of mercury in the communicating vessels Q. ¹ and R is reduced, whereby screw Z comes out of contact with the mercury column in R. .

Through this contact opening, the current which would be closed by the re-immersion of the wire D in the mercury ^{mass Q 2} when H ¹ rises, with otherwise the same conditions, is in turn interrupted. Of course, this second interruption (between Z and W) must be effected before the first interruption point (between D and V) is closed again.

The interruption of the current between Z and W lasts until, through the gradual, slower discharge of the mercury from the narrow opening in the bottom of G ¹ , the vessel R (in communication with Q. ¹ ) has again filled up with mercury to such an extent that a Contact between the mercury and the lower tip of the regulating screw Z is re-established. Then the game of the apparatus begins anew, as described above.

If the dimensions of the bowl G ¹ and its outflow opening are such that the mercury flows out for a certain time, about just one minute, the lever arm H ^{1 is} always drawn in exactly after this time has elapsed, for example after one minute will.

A gripping arm P placed on H ⁱ insulated or any other, differently designed device is used to mechanically move a switch-on device for another electrical current, through whose short-lasting closing takes place every ι minute pointer mechanisms or other devices can be moved.

However, instead of this current to be switched on by P, the current used to drive the apparatus can also be used directly for any mechanical work to be effected in certain periods of time.

Claims (1)

Patent claim: Electromagnetic switching mechanism, which automatically carries out a movement in certain periods of time or sends a current in a line, characterized in that at each end of a double-armed lever under the action of an electromagnet (E) a vessel (B ¹ or B ² ) with perforated bottom and immersed in a mercury bath (Q ¹ or Q ² J) forming an electrical connection point of the electromagnetic circuit, so that when the electromagnetic circuit closes at a third electrical connection point (U) , the lever arm (H ¹ ) forming the armature of the electromagnet (E) and one vessel (G ² ) is lifted until the mercury bath (Q ² ) is interrupted due to the mercury flowing out of the vessel and is not closed again when the lever returns to its original position is uplifted until, according to the leakage of the mercury from the previously immersed and therefore filled Vessels (G ¹ ) the mercury in the associated bath rises to the power supply pin (Z) , whereupon the game repeats itself again.
