Zusatz zum Patent No.34113 vom 18. Juni 1885.Addendum to patent number 34113 from June 18, 1885.
Patentirt im Deutschen Reiche vom 6. März 1886 ab. Längste Dauer: 17. Juni 1.900.Patented in the German Empire on March 6, 1886. Longest duration: June 17, 1,900.
Die in dem Zusatz - Patent No. 36792 beschriebene Glocke giebt kräftig tönende Schläge und eignet sich daher vornehmlich für solche Räume, wo die Glockensignale trotz anderem Geräusche deutlich gehört werden sollen, bedarf aber wegen des zweiten Magnetenpaares eines sehr starken Stromes. .The patent no. The bell described in 36792 emits powerfully sounding strikes and is therefore particularly suitable for rooms where the bell signals despite other things Noises should be heard clearly, but this is necessary because of the second pair of magnets a very strong current. .
Um nun diese Rassel- und Schlagglocke auch zur Anwendung in solchen Räumen geeignet zu machen, wo man, wie z. B. in Krankenzimmern, kräftige Glockenschläge zu vermeiden hat, wurden an derselben folgende Neuerungen getroffen. .So now this rattle and chime is also suitable for use in such rooms to make where to, such as B. in hospital rooms to avoid strong bells has, the following innovations were made on the same. .
Das zweite Magnetenpaar w w sowie der Hebel / und der Contactstift g in der Schwungscheibe d kommen in Wegfall, und an deren Stelle tritt eine dritte Polklemme η zu den bereits vorhandenen 0 und ρ hinzu. Letztere beiden sind positive Pole, erstere ist ein negativer Pol. Mittelst eines Contactdrückers werden η und 0 zu einem und mittelst eines zweiten Contactdrückers η und ρ zu einem anderen Stromkreise verbunden.The second pair of magnets ww and the lever / and the contact pin g in the flywheel d are no longer used, and a third pole terminal η is added to the already existing 0 and ρ in their place. The latter two are positive poles, the former is a negative pole. One contact button connects η and 0 to one circuit, and a second contact button connects η and ρ to another circuit.
Bei Herstellung des Stromkreises η ρ geht der Strom von η durch die Rollen s s und das Gestell χ nach dem Anker i, von diesem nach dem Contactständer * f und von hier nach p. Es ist also der Stromkreis in Dienst gestellt-, welcher das Rasseln veranlafst. Die Vibrationen, welchen bei diesem Rasseln der· Anker t unterliegt, werden durch das Ende k des Ankers und den Stift h in der Schwungscheibe d dieser mitgetheilt. Das durch die excentrische Lage des Schwerpunktes der Schwungscheibe d erhöhte Beharrungsvermögen derselben hindert die letztere, den Vibrationen des Ankers t mit gleicher Schnelligkeit zu folgen; es wirkt daher die Schwungscheibe d rückwärts auf den Anker t und hindert denselben am energischen Aufschlagen an. die Magnete s und somit auch in gleicher Weise den Hammer in seinen auf die Glocke geführten Schlägen; letztere werden abgeschwächt und kommen gedämpfter zum Gehör.When the circuit η ρ is established, the current goes from η through the rollers ss and the frame χ to the armature i, from this to the contact stand * f and from here to p. So it is the circuit that causes the rattling to be put into service. The vibrations to which the armature t is subjected during this rattle are communicated to the flywheel d by the end k of the armature and the pin h in the flywheel d. The increased inertia of the flywheel d due to the eccentric position of the center of gravity prevents the latter from following the vibrations of the armature t with the same rapidity; therefore the flywheel d acts backwards on the armature t and prevents the same from energetic impact. the magnets s and thus in the same way the hammer in its blows on the bell; the latter are weakened and heard more muffled.
Wird der Stromkreis η ο mittelst des dazu gehörigen Contactdrückers geschlossen, so geht der Strom von η durch die Rollen ss und das Gestell χ nach dem Anker t, von diesem durch Vermittelung der Contacte k h .nach der Schwungscheibe d und von dieser nach o. Nach dem bekannten, in dem Zusatz-Patent No.. 36792 näher erläuterten Vorgang giebt die Glocke einzelne Schläge in entsprechend grofsen Intervallen.If the circuit η ο is closed by means of the associated contact pushbutton, the current goes from η through the rollers ss and the frame χ to the armature t, from this by means of the contacts kh. To the flywheel d and from this to o the known process, which is explained in more detail in the additional patent No. 36792, the bell gives individual strikes at correspondingly large intervals.
Auch diese einzelnen Schläge tönen gedämpfter, was nur darin seine Erklärung finden kann, dafs durch die Anlage einer zweiten negativen Leitung, welche von denselben Elementen ausgeht, eine Abschwächung des Stromes verursacht wird.These individual beats also sound more muted, which can only be explained in this can, by the installation of a second negative line, which is made of the same elements goes out, a weakening of the current is caused.
