Description
<Desc/Clms Page number 1>
Kugellager für den Schallarm von Plattensprechmaschinen.
EMI1.1
<Desc/Clms Page number 2>
unteren Fläche des Flansches 6 und der oberen Kantenfläche der Hülse 9 derart eingesetzt, dass der Ring 11 sich in seiner Horizontalebene frei drehen kann. Hiebei liegt der Ring 11 in derselben Horizontalebene wie die Mittelpunkte der Kugeln 10.
Die Hülsenstücke 5,9, die die äussere Hälfte der Kugellaufbahn bilden, können durch geeignete Mittel, beispielsweise durch Schrauben 13 od. dgl., miteinander verbunden sein. Die unteren Enden der Hülsenstücke 5 und 9 liegen in der gleichen Ebene wie die Tischplatte des Sprechmaschinengehäuses.
Die vorliegende Einrichtung ermöglicht nicht nur eine leichte Bewegung des Schallarmes 1 um eine vertikale Achse, sondern gewährleistet auch einen guten Halt des Schallarmes 1, so dass das freie Ende 14 des Schallarmes sich weder merklich aufwärts, noch abwärts bewegen kann und der Schallarm auch nicht klappert.
PATENT-ANSPRÜCHE.
EMI2.1
der Aussenseite des Schallarmknies (2) und aus zwei im Querschnitt annähernd viertelkreisförmigen Rillen (4, 8) an den inneren Kanten bzw. an einwärts gerichteten Flanschen zweier ineinandergesteekter Hübenstücke (5, 9) zusammengesetzt ist, die das Ende des Sehaliarmknies umgeben und von denen das eine (5) auf dem Sprechmaschinengehäuse befestigt ist.

lower surface of the flange 6 and the upper edge surface of the sleeve 9 inserted so that the ring 11 can rotate freely in its horizontal plane. The ring 11 lies in the same horizontal plane as the centers of the balls 10.
The sleeve pieces 5, 9, which form the outer half of the ball raceway, can be connected to one another by suitable means, for example by screws 13 or the like. The lower ends of the sleeve pieces 5 and 9 lie in the same plane as the tabletop of the speaking machine housing.
The present device allows not only a slight movement of the sonic arm 1 around a vertical axis, but also ensures a good hold of the sonic arm 1 so that the free end 14 of the sonic arm can neither move noticeably up nor down and the sonic arm does not rattle .
PATENT CLAIMS.
EMI2.1
the outside of the elbow arm (2) and two grooves (4, 8) with a cross-section of approximately quarter-circle on the inner edges or on the inwardly directed flanges of two nested lifting pieces (5, 9) which surround the end of the elbow arm and which one (5) is attached to the speaking machine housing
