Patentirt im Deutschen Reiche vom 26. August 1883 ab.Patented in the German Empire on August 26, 1883.

Die Erfindung besteht in einer neuen Art der Bildung inducirter Körper (Ringe, Scheiben u. s. w. irgend welcher Art).The invention consists in a new way of forming induced bodies (rings, disks and s. w. of any kind).

Gewöhnlich werden die inducirten Körper mit isolirtem Draht umwickelt, und es ist bekannt, welche Schwierigkeiten man bei diesen Arbeiten zu überwinden hat, um einen Körper zu erhalten, welcher zugleich vollständig rund, gänzlich isolirt und insbesondere vollkommen äquilibrirt ist. Um diese Schwierigkeiten zu vermeiden, soll die Herstellung der inducirten Windungen dieser Körper entweder durch Giefsen oder auf elektrolytischem Wege bewirkt werden, so dafs dann eine leichte Bearbeitung dieser Körper zur vollständigen Aequilibrirung derselben möglich wird. Es werden zu diesem Zwecke an denjenigen Stellen des Eisenkernes, welche die inducirte Spirale einnehmen soll, geeignete Isolirungen in passender Weise angebracht, und zwar durch Aufstecken von Scheiben aus isolirendem Material, welche zweck mäfsige Ausschnitte haben, so dafs die Verbindung der einzelnen Windungen mit einander bei dem späteren Giefsen bezw. bei dem Niederschlagen des Metalles auf elektrolytischem Wege erreicht wird.Usually the induced bodies are wrapped with insulated wire, and it is known what difficulties one has to overcome in this work to get a body which is at the same time completely round, completely isolated and, in particular, completely is equilibrated. In order to avoid these difficulties, the preparation of the should be induced Windings of these bodies are effected either by casting or by electrolytic means so that a slight treatment of these bodies for complete equilibration same becomes possible. For this purpose, at those points of the iron core, which the induced spiral is to occupy, appropriate insulation attached in a suitable manner, by attaching disks made of insulating material, which are expedient Have cutouts so that the connection of the individual turns with each other in the later Giefsen respectively. at the knockdown of the metal is achieved electrolytically.

Diese Zwischenräume werden derart bemessen, dafs der Querschnitt derselben gleich ist dem Querschnitt der inducirten Spirale. Der so vorbereitete Körper wird einfach in das elektrolytische Bad getaucht und in demselben so lange belassen, bis der Niederschlag in der erforderlichen Dicke sich gebildet hat, oder das betreffende Material wird über den so präparirten Kern gegossen, so dafs dasselbe an den isolirten Stellen haften bleibt. Man erhält auf diese Weise eine Spirale ohne Ende und ohne Unterbrechung der Continuität, welche man nur in der gewöhnlichen Weise mit den Lamellen des Collectors zu verbinden hat.These spaces are dimensioned in such a way that the cross-section thereof is the same is the cross-section of the induced spiral. The body so prepared is simply put into that immersed in the electrolytic bath and left in the same until the precipitate in the required thickness has formed, or the material concerned is over the so prepared Poured the core, so that it adheres to the isolated places. One receives on this way a spiral without end and without interruption of the continuity, which one only has to connect in the usual way with the lamellas of the collector.

Die beiden beschriebenen Methoden der Herstellung der mducirten Windungen durch Giefsen oder auf elektrolytischem Wege können auch für die Herstellung von inducirenden Elektromagneten benutzt werden.The two described methods of making the shaped coils by Giefsen or by electrolytic means for the production of inductive electromagnets to be used.

Sowohl bei dem elektrolytischen Verfahren, als bei der Herstellung der inducirten Spirale durch Gufs beabsichtigen die Erfinder, irgend ein beliebiges leitendes Material zu verwenden; in letzterem Falle aber (also beim Giefsen) empfiehlt sich besonders Aluminium, dessen Schmelzpunkt verhältnifsmäfsig niedrig liegt, wodurch die Operation erleichtert wird.Both in the electrolytic process and in the manufacture of the induced spiral by Gufs the inventors intend to use any conductive material; in the latter case (i.e. in casting), aluminum is particularly recommended, its melting point is relatively low, which makes the operation easier.

Auf der beiliegenden Zeichnung ist der isolirte inducirte Kern dargestellt, wie er in die" Gufsform oder in das elektrolytische Bad gebracht werden soll.In the accompanying drawing the isolated induced nucleus is shown as it is in the " Casting mold or to be brought into the electrolytic bath.

Die Fig. 1 und 2 zeigen in Ansicht und Schnitt die Anordnung der isolirenden Spirale a auf dem Kern c,. in deren leeren Zwischenräumen die leitende inducirte Spirale b durch1 and 2 show in a view and section the arrangement of the insulating spiral a on the core c ,. in the empty spaces between them the conductive induced spiral b passes through
