Abstract
The object of this invention is to provide an improved phonograph having an improved tone arm assembly and structure associated therewith for automatically returning the tone arm to its rest position when the phonograph cover is closed. The improved tone arm is mounted in a slightly unbalanced condition for movement under the influence of gravity to a normal position. In this normal position the up and down motion of the needle on the record and the force exerted thereagainst is independent of the tone arm.
