Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Oberhalb der Membran eines Telephons (s. beiliegende Zeichnungen) ist, concentrisch die Oeffnung des Schalltrichters umschliefsend, ein eiserner Ringr von winkelförmigem (| ) Querschnitt angebracht, Fig. 1. Dieser Ring ist umschlossen von einer Inductionsrolle aus feinem isolirten Kupferdraht, in welcher durch die sogenannte Ueberregung, d. i. durch die von der Membran noch nicht gebundenen Kraftlinien, Inductionsströme erzeugt werden. Diese Ströme werden in den Hauptstromkreis der auf dem Magneten befestigten Inductionsrollen eingeschaltet. Above the membrane of a telephone (see attached drawings) is, concentrically, the Surrounding the opening of the bell, an iron ring with an angular (|) cross-section attached, Fig. 1. This ring is enclosed by a fine induction roller insulated copper wire, in which the so-called overexcitation, i.e. i. by the Membrane not yet bound lines of force, induction currents are generated. These currents are switched into the main circuit of the induction rollers attached to the magnet.
Anstatt des Ringes von winkelförmigem (| ) Querschnitt kann auch, besonders bei Anwendung hufeisenförmiger Magnete im Telephon, oberhalb der Membran, die Oeffnung des Schalltrichters concentrisch umschliefsend, ein Ring R, Fig. 2 und 3, angeordnet werden. Dieser Ring trägt an den Stellen, die den beiden Polen des im Telephon befindlichen Hufeisenmagneten gegenüberstehen, je einen Ansatz α von der Form des Stückes eines Kreisringes. Jeden dieser beiden Ansätze umgiebt eine Inductionsspule (in der Figur nur durch die unterbrochenen Linien angedeutet), welche in entgegengesetzter Richtung gewickelt sind. Die Anfänge der beiden Spulen sind mit einander verbunden, die Enden werden in den Hauptstromkreis der auf dem Magneten befestigten Inductionsrollen eingeschaltet. Instead of the ring of angular (|) cross-section, a ring R, FIGS. 2 and 3, can also be arranged above the membrane, especially when using horseshoe-shaped magnets in the telephone, concentrically enclosing the opening of the horn. This ring carries at the points which face the two poles of the horseshoe magnet located in the telephone, each an approach α of the shape of a piece of a circular ring. Each of these two approaches is surrounded by an induction coil (only indicated by the broken lines in the figure), which are wound in opposite directions. The beginnings of the two coils are connected to each other, the ends are switched into the main circuit of the induction rollers attached to the magnet.
