AUTOMATIC RECORD PLAYER MECHANISM FOR TURNTABLE SPEED AND PICK-UP ARM POSITION ADJUSTMENT

摘要

A device in a turntable or in a turntable for the combined adjustment of the speed of the turntable and the lowered position of the pickup arm on the edge of a disc that has been placed on the turntable in order to be reproduced, being dictated the lowering position of the pickup arm by application with a lever step of a two-arm shift lever which is pivotable about a horizontal axis, whose step has been selected by a sensing means, characterized in that the free end of a lever single-arm dead center is applied with the shift lever by means of a neutral spring in one of two functional speed adjustment positions, while during the pivoting of the shift lever, in order to bring a lever step for another diameter of descent to the path of the pickup arm, the free end is pivoted beyond the neutral point by said lever and oscillates against a n switch that changes speed.
