Abstract

328,222. Parker, T. H. Jan. 21, 1929. Tone-arm joints.- A tone-arm is supported on a helical spring which permits swinging movement of the arm and overcomes the tendency of the stylus to bear on the outer side of the sound track. As shown, the spring 3 engages screw threaded bosses 1, 4 on the arm 2 and mounting respectively, and the spring is unstressed when the stylus is at the end of the track but is stressed when the stylus is transferred to the starting groove. The boss 1 may be extended and bevelled to bear on a bevel support on the mounting, and a flexible connection may extend between these parts.
