CLASS 21: Electrical apparatus.

Addition to the patent M 7205g of October 2, 1892.

Patented in the German Empire by ig. August 1893. Longest duration: October 1, 1907.

The present invention relates to a modification to that protected by Patent No. 72059, electrically operated pendulum switch. On the one hand, the amendment has the purpose of being reliable Establishing and securing the electrical connection, on the other hand it concerns a new one Type of current circuit formation, furthermore the arrangement of damping springs, and finally also Another particularly simple device for switching the pendulum moving on and off Electromagnets.

The subject is shown in the drawing.

1 to 5 illustrate the establishment of a boat-shaped Stromschlufsstückes once in a vertical and once in a horizontal arrangement.

Figs. 6 and. 7 illustrate a new device for establishing the current circuit when swinging the pendulum back and forth.

In Fig. 8 the arrangement of damping springs is shown.

Fig. 9 shows the extremely simple arrangement of a switch for moving the electromagnets.

In Fig. Ι the electromagnets E and E ¹ on the one hand to their associated Stromschlufsteile G and G \ but on the other hand through the battery to the pendulum C equipped with the Stromschlufsarmmen -F and F ^{1 connected.}

When swinging back and forth, the formation of the current should always be reliable take place in such a way that the electromagnet to which the pendulum approaches is always switched on.

and that the same electromagnet is always automatically switched off when the pendulum has completed its rash on this side.

As Fig. 5 shows on a larger scale, the upper part α of the electrical connection piece consists of metal, but the lower part b consists of insulating material; in the latter, a steel sheet is at the top, which accommodate the Stofs of PUFA used Stromschlufshebels s, to reduce the wear.

For the purpose of reliable power supply and security, the power connection pieces G and G ^{1 are surrounded} by coulisse-like guides. Each of the latter consists, as Fig. 5 shows, of a simple lifting spring or composed of several leaves, which has the purpose of lifting the button of the power circuit lever F ¹ when going back so far that it hits the The upper part α , which gives the current circuit, arrives.

The movement of the power circuit lever F ^] is so dimensioned that the power circuit button of the same ^{always just bypasses the power circuit piece G 1} without coming completely out of the area of the spring y. When the pendulum has completed its stroke, the power button of Figures 1 and 5 will fall due to its own gravity; at the beginning of the new stroke, however, it must be lifted especially if the current circuit arm F ¹ does not do this by its own spring force.

Furthermore, a guide rail c is provided 'on which the power button of the arm F ¹ slides when going back, so that the

Lifting spring y is relieved as much as possible and only to work at the right moment.

For the purpose of soundproofing, the rail c is covered with leather.

In the arrangement illustrated in FIGS. 1, 2 and 5, a damping rail d, which is also covered with leather for the purpose of sound dampening, is then provided.

In FIGS. 3 and 4, the boat-shaped electrical connection piece is arranged horizontally and, instead of the damping rail d , a second lifting spring is provided.

The support rails c are then arranged in such a way that the power button of the power switch lever F ¹ must always slide close to the power ^{connector G 1.} Shortly before the pendulum completes its swing, the power button then passes between the power connector G and the spring f ¹ ; When going back, the power button then slides along the isolating part b until it is between, shortly before the end of the drop. the Stromschlufsstück G ¹ and the Feder_ / passes through.

Since the springs f ^{or / 1} always return to their rest position immediately after the electric circuit button has been pushed through, they urge the electric circuit lever F ¹ when swinging towards the current circuit-giving part α and when swinging back onto the insulating part b.

In FIGS. 6 and 7 the actual current-supplying part consists of a metal slide rail a ¹ which is attached to an insulating plate b ^1. The Stromschlufsarm F ^L carries at its free end a rotatably mounted cube in (Fig. 7) made of insulation material. In this a piece of metal η is used on its ropes facing the Stromschlufsschiene, which respectively with the Stromschlufsarm F ^1. the pendulum C has metallic contact.

When going down, the piece of metal η grinds on the metal rail a ¹ and falls onto the insulation plate b ^l at the end of the slope. When retrogression of the cube m stöfst against the metal piece a \ rotates as a result by 90 ⁰ and then grinds with the insulated side to the metal rail back until it drops again.

At the next exit, the metal surface of the cube hits the metal rail α ¹ ; as a result, it turns back 90 ^° and the game begins again.

In Fig. 8 the pendulum with the damping springs ρ respectively. p ^] equipped, which respectively to the appropriately made of rubber approaches of the buffer stand P. Hit P ¹ to relieve them of the material a little.

In Fig. 9, the movement of the electromagnets E respectively. E ¹ is caused in the simplest way by the fact that the magnet E is connected to an electrical connection piece χ and the magnet E ^{1 is} connected to an electrical connection piece x ¹ . A these two Stromschlufsstücken common switch \ is moved by the shuttle C in such a way that always turned off the associated magnet at the completion of a vibration and the other is turned on. The mode of action is evident from the drawing without further ado.
