Abstract

335,004. Hunter, H. K. July 26, 1929. Sound-boxes and tone-arms, balancing and resiliently supporting; varying stylus pressure, means for.-In sound recording and reproducing apparatus of the type in which the tone-arm or piok-up arm is counterbalanced, and in which the stylus is urged towards the record by means independent of gravity action, a damper controls the movements of the stylus towards or away from the record. As shown, a. pick-up arm 5 is carried in a beam 4 pivoted horizontally on a pin 3 carried by a trunnion 2. The latter has a bracket 11 and is pivoted in a pedestal 1. The counterbalance weight consists of a duplicate pick-up device. A tension spring 10 having an adjusting nut 10<a> urges the stylus towards the record, and the damper consists of a, dashpot 13, the devices 10, 13 being connected to the bracket 11 and the beam 4. The spring 10 and dashpot 13 are interchangeable.
