Description
Die vorliegende Erfindung betrifft eine Verbesserung der An- und Abstellvorrichtung für Plattensprechmaschinen gemäß Patent 569 526. Bei dieser Vorrichtung hat der Bremsauslösehebel zwei Zähne, die von dem Anschlagstift eines Schaltrades bewegt werden. The present invention relates to an improvement in the positioning and positioning device for record speaking machines according to patent 569 526. In this device, the brake release lever has two teeth that are separated from the Stop pin of a ratchet wheel are moved.
Gemäß der vorliegenden Erfindung sindAccording to the present invention are
die Zähne des Auslösehebels an -einem besonderen, an dem Hebel längsverschiebbaren Teil angebracht, der durch eine Feder in seiner Endstellung gehalten wird.the teeth of the release lever on a special one that is longitudinally displaceable on the lever Part attached, which is held in its end position by a spring.
Diese Ausbildung bietet den Vorteil, daß infolge der Nachgiebigkeit der Zähne Stöße bei deren Mitnahme und infolgedessen Tonschwankungen vermieden werden.This training has the advantage that shocks due to the resilience of the teeth when taking them with you and as a result, sound fluctuations are avoided.
Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt, und
zwar in
ae> Abb. ι im Grundriß und inIn the drawing, the object of the invention is shown, for example, in
ae> Fig. ι in plan and in
Abb. 2 in Seitenansicht, in Richtung der Pfeile gemäß Abb. 1 gesehen.Fig. 2 in side view, seen in the direction of the arrows in Fig. 1.
Die Zähne 1 und 2 des Auslösehebels 3 sind an dem Teil 4 gebildet, der längsverschiebbar an dem Hebel 3 angeordnet ist. Zu diesem Zweck besitzt der Hebel 3 einen Schlitz 5, durch den zwei Schrauben 6 hindurchragen, die in dem Teil 4 sitzen. Der Abstand der Schrauben 6 ist geringer als die Länge des Schlitzes, so daß der Teil 4 sich, in der Längsrichtung verschieben kann. Durch eine unter dem Hebel 3 liegende Feder 7 wird der Teil4 in seine Endstellung, d.h. nach dem Ende des Hebels 3 hin, gedrückt.The teeth 1 and 2 of the release lever 3 are formed on the part 4 which is longitudinally displaceable is arranged on the lever 3. For this purpose, the lever 3 has a slot 5 through which two screws 6 protrude, who sit in part 4. The distance between the screws 6 is less than the length of the slot, so that the part 4, can move in the longitudinal direction. By a spring 7 located under the lever 3 the part 4 is pushed into its end position, i.e. towards the end of the lever 3.
Der Hebel 3 ist in dem dargestellten Ausführungsbeispiel mit einem einstellbaren Anschlag 8 versehen. Dieser besteht aus einer exzentrisch gelagerten Scheibe, an welcher die eine der Schrauben 6 zum Anschlag kommt.The lever 3 is in the illustrated embodiment provided with an adjustable stop 8. This consists of an eccentrically mounted disc on which the one of the screws 6 comes to a stop.
Besonders vorteilhaft ist es, den Teil 4 nicht aus Metall, sondern aus einem nachgiebigen Stoff, insbesondere Vulkanfiber, herzustellen. Hierdurch wird ein besonders weicher Gang erzielt.It is particularly advantageous if the part 4 is not made of metal, but of a flexible one Manufacture of fabric, especially vulcanized fiber. This results in a particularly smooth gait.
