Abstract

292,703. Smith, W. T., and Smith, W. A. March 29, 1927. Sound-boxes, arrangement of; tone-arm joints. -Relates to gramophones or the like in which means are provided for maintaining the soundbox parallel to its original position, as it moves across the record, so that the needle is always approximately tangential to the sound-groove, and consists, in a. particular construction and arrangement of parts for this purpose, as follows. The goose-neck A<1> carrying the sound-box B is mounted in a block e, so that it can swivel in the usual manner about an horizontal axis. The block e is fitted in a cylindrical part E at the end of the tone-arm A, and is mounted so that it has a limited rotary movement, about a pin e<2>. An arm or stud e<1> projects from the block e through the part E, and a link G pivotally connects the arm e' to a pivot F fixed near the base of the tone-arm. By this arrangement, the link G controls the position of the sound-box in the manner stated above.
