Abstract

320,868. Sykes, A. F. April 19, 1928. Sound-reproducing devices, supportting. - A sound-box or pick-up is adjustably mounted for playing hill-and-dale or zig-zag records, and is maintained in correct tangential relation to the sound grooves on the record throughout playing by mounting it on pivots B at the end of the supporting arm 2 and controlling it by an arm 10 thereon connected by a link 11 to a fixed arm 12 on the mounting for the arm 2. When a hollow arm 2 is employed, the link 11 may extend through it, and the radial distances of the pivot connections of the link from the centres of movement of the sound-box and tone-arm may be different to produce a predetermined rocking movement of the sound-box relatively to the tone-arm. The sound-box or pick-up 1 is mounted in a sleeve on an arm 7 mounted on a pivot at rightangles to the pivot B, and may be rotated in the sleeve by a, head 9 for playing either hill-and-dale or zig-zag records.
