Abstract
194,257. Huth, W. H. March 2, 1922, [Convention date]. Returning sound-box to starting point.-Relates to repeating-devices of the kind which rest on the record and, when the needle reaches the finishing position, turn with the record to lift the needle and return it to the starting position. The device comprises a body 1, which may be of sheet steel, formed to provide a cam-groove 10 having a hard and smooth surface on which the point of the needle may slide freely without scratching. The device is held against rotation, during the playing of a record, by a radial arm 21 engaging the side of the needle. The edge of the arm engaged by the needle is formed of soft rubber so as not to interfere with the vibrations of the needle. When the needle has moved inwards beyond the end 23 of the arm, the device turns with the record, the edge 24 slips under the needle and the converging spiral cam-groove 10 guides the needle outwards and deposits it on the record at the starting position.
