Der in der beigefügten Zeichnung dargestellte Apparat besteht aus dem aus Hartgummi hergestellten Gehäuse h, dem Elektromagneten E und Anker a. CC sind die Stell- bezw. Contactschrauben, während s eine Spiralfeder und \ die Schreibspitze darstellt.The apparatus shown in the accompanying drawing consists of the housing h made of hard rubber, the electromagnet E and armature a. CC are the Stell- respectively. Contact screws, while s represents a spiral spring and \ the writing tip.
In dem Augenblick, in dem zwischen den Contactschrauben und dem Anker α durch die Federkraft der Spirale s Contact hergestellt wird, ist der Stromkreis geschlossen und der Elektromagnet zieht den Anker a an.At the moment when contact is established between the contact screws and the armature α by the spring force of the spiral s , the circuit is closed and the electromagnet attracts the armature a .
Man bethätigt den Apparat in der Weise, dafs man mit demselben wie mit einer Feder schreibt oder zeichnet. Hierbei wird die Spitze Z fortwährend kleine Löcher in das Papier einstechen, da der Anker α fortwährend durch den Elektromagneten E angezogen und durch die Spiralfeder s abgezogen wird (Fig. 1).The apparatus is operated in such a way that one writes or draws with it as with a pen. Here, the tip Z will continuously pierce small holes in the paper, since the armature α is continuously attracted by the electromagnet E and withdrawn by the spiral spring s (Fig. 1).
Statt dieser Einrichtung kann man auch zwei über einander stehende Elektromagnete (Fig. 2) E und Ελ anwenden, zwischen welchen abwechselnd Leiter und Isolatoren angebracht sind. Tritt z. B. der Strom durch Draht 1, so geht er durch Ringstück b, die Scheibe c, Ringstück b1 und Draht 2 in die Windungen des Elektromagneten E1 herum. Der Anker wird also nach oben angezogen, bis die Scheibe c sich zwischen Ringstück b und b2 befindet, so dafs nunmehr der Strom durch Draht 1, Ringstück b, Scheibe c, Ririgstück b2 und Draht 3 in die Windungen des Elektromagneten E gelangt. :Es wird daher die Platte c wieder nach unten gezogen, worauf sich das Spiel fortwährend wiederholt und eine ebensolche Bethätigung der Spitze Z bewirkt.Instead of this device, one can also use two electromagnets (Fig. 2) E and Ε λ standing on top of one another, between which conductors and insulators are attached alternately. Occurs z. B. the current through wire 1, it goes through ring piece b, the disc c, ring piece b 1 and wire 2 in the turns of the electromagnet E 1 around. The armature is therefore pulled upwards until the disk c is between ring piece b and b 2 , so that the current through wire 1, ring piece b, disk c, ring piece b 2 and wire 3 now passes into the windings of electromagnet E. : The plate c is therefore pulled down again, whereupon the game is continuously repeated and the tip Z is actuated in the same way.
Der so durchstochene Bogen wird auf einen anderen gelegt, eingefärbt, worauf die Farbe durch die Löcher dringt und sich auf dem untergelegten Bogen zu der Zeichnung etc. verbindet. Auf diese Weise kann man natürlich beliebig viele Exemplare herstellen.The thus pierced sheet is placed on another, colored, whereupon the color penetrates through the holes and attaches itself to the drawing etc. on the sheet underneath. connects. In this way you can of course make as many copies as you want.
