Abstract

194,082. Tootill, S. Jan. 25, 1922. Tone-arm joints.-In a portable gramophone or the like, in order to make the machine compact the tone-arm is so mounted that it can be lowered when not in use. The mounting comprises a socket c having inclined and horizontal slots or grooves c<1>, c<2> with which engage pivotpins d projecting from a collar b<2> on the tone-arm. The tone-arm is shown in its lowered position, from which it is raised by rotating it,' whereupon the pivots d ride up the inclined slots c<1> into the horizontal slots c<2>. The pivots d may be constituted by the ends of a rod passing diametrically through the tone-arm.
