<p>An automatic record player changer mechanism which includes a cylindrical column having a longitudinal groove within the column running the entire length thereof, a first lever of less length than the groove positioned therein, and pivotable near its midpoint about a fulcrum, a record supporting tooth near the top end of the lever creating a perforation in the column and a small axially movable second lever above the tooth composed of two identically rolled pieces each having a curved slot therein and positioned within the groove by passage of a pin through the slots and column. The first lever has a perforation therein near its upper end into which a ball is positioned. The longitudinal groove has a transverse groove in each side thereof extending upwardly toward the tooth and into which the ball is placed so that upon pivoting the first lever about the fulcrum the lever moves in an ascending or descending transverse direction to the axis of the column.</p> |
