  Vorrichtung zur Regulierung der   Lautstärke   an Grammophonen. 



   Die Erfindung betrifft eine Vorrichtung zur Regulierung der   Lautstärke   von Grammophonen. 



  Sie besteht darin, dass diese Regulierung dadurch herbeigeführt wird, dass entweder eine lange Grammophonnadel oder ein zur Verlängerung einer kurzen Grammophonnadel dienender langer Nadelhalter an beliebigen Stellen durch Anpressen einer Klemme oder auch nur eines Querstüekes, Ringes od. dgl. an der vollen Ausschwingung verhindert wird. 



   Die Vorrichtung ist in Fig. 1 in Seitenansicht, teilweise im Schnitt, in Fig. 2 von   rückwärts   gesehen dargestellt. Die Stange a, welche den Träger des ganzen Apparates bildet, wird mit ihrem nach aufwärts gebogenen, in eine Spitze auslaufenden Ende bin jenem Teil der Sehalldose   festgeschraubt,   der sonst zur Aufnahme der Nadel bestimmt ist. An dem senkrechten Teil der Stange a ist ein Querstück c aufgekeilt, an welchem eine mit einem   Längsschlitz   versehene Platte e befestigt ist. Auf dieser 
 EMI1.1 
 höher oder tiefer gestellt wird, kann der Nadelhalter mehr oder weniger ausschwingen, wodurch die Tonwiedergabe lauter oder leiser wird.

   Die Feder q wirkt als Reibungsbremse und ermöglicht die Fixierung des Zahnrades in jeder beliebigen Höhe.   H   ist eine Öffnung im Nadelhalter, in welcher die Nadel   n   mittels der Schraube   p   befestigt wird. 



   Selbstverständlich ist die Herstellung des Apparates nicht an die geschilderte und dargestellte   Ausführungsform gebunden   ; es kann z. B. anstatt des Zahnrades eine beliebige andere Gleit-und

  Device for regulating the volume of gramophones.



   The invention relates to a device for regulating the volume of gramophones.



  It consists in the fact that this regulation is brought about by preventing either a long gramophone needle or a long needle holder serving to extend a short gramophone needle at any point by pressing a clamp or even just a cross piece, ring or the like from full oscillation .



   The device is shown in Fig. 1 in side view, partially in section, seen in Fig. 2 from the rear. The rod a, which forms the support of the whole apparatus, is screwed with its upwardly bent end ending in a point into that part of the Sehall can which is otherwise intended to receive the needle. On the vertical part of the rod a, a cross piece c is keyed, to which a plate e provided with a longitudinal slot is attached. On this
 EMI1.1
 is set higher or lower, the needle holder can swing more or less, making the sound reproduction louder or quieter.

   The spring q acts as a friction brake and enables the gear wheel to be fixed at any height. H is an opening in the needle holder in which the needle n is fastened by means of the screw p.



   Of course, the manufacture of the apparatus is not bound to the described and illustrated embodiment; it can e.g. B. instead of the gear any other sliding and
