INTERCHANGEABLE STYLUS ASSEMBLY FOR PLAYER CARTRIDGE

摘要

A phonograph cartridge replaceable stylus assembly is provided. The assembly comprises a housing having a nonmagnetic tube affixed thereto. The tube has a forward end and a rear end extending outwardly away from the housing. A nonmagnetic stylus arm extends through the tube forward end. A jeweled stylus is mounted to the front of the arm. The rear end of the arm passes through an elastomeric damper positioned within the tube. The damper serves as a universal pivot joint for the arm. The damper comprises a cylindrical member having a forward edge and a rear edge. The tube is crimped along a circular crimp line engaging the damper intermediate the forward and rear edges with the portions of the damper that do not engage the crimp also being free of the tube. A magnetic member is positioned within the tube secured to the arm and adapted to move therewith in response to motion of the jeweled stylus and following the grooves of a record. The arm passes through and extends beyond the magnetic member terminating within the elastomeric damper in front of the crimp. A tension-free tie wire extends rearwardly from the rear of the arm and is secured to the tube. The tie wire serves to restore the arm and hence the magnetic member to its zero position.
