Abstract
211,290. Cotton, A. F. R. Dec. 19, 1922. Tool arms.-A stylus bar is connected to the diaphragm without metallic contact by a connection, adapted to transmit substantially only the vibrations normal to the diaphragm comprising a plate f on the end of the bar c embedded in wax g, or similar substance, capable of hardening, in a cup o fixed to the diaphragm a. The Provisional Specification describes a modification in which the stylus bar is connected to the diaphragm by a screw passing through a clearance hole in the diaphragm, metallic contact being broken by two washers of wax, rubber or the like.
