Abstract

323,780. Cooper, W. F. Oct. 10, 1928. Mandrels ; tone-arms; tone-arm joints; cylindrical and like records.- Conical records 9, such as those described in Specifications 316,595 and 316,596, or cylindrical records, are mounted on a holder 6 which rotates about a substantially horizontal axis, the motor 4 and holder 6 being arranged above a box-like casing 1 forming the horn chamber, one wall 15 of the horn lying along the floor of the casing and the opposite wall 16 comprising a partition lying beneath the motor and holder. The tone-arm 20, which may be of exponential form, extends from the rear of the horn upwardly to a sound-box 22 situated above the record and rocks about an axis 23 during playing. The motor 4 is mounted in a compartment formed hy partitions 2, 3, and the records are mounted by arms 8 on the holder 6 carried by the driving spindle 5. A spider 10 and nut 11 serve to secure the records. The sound-box may be adjusted to the right or left of the position shown in Fig. 3, to vary the pressureof the needle. The axis of the spindle 5 may be tilted to bring the playing portion of a conical record into the horizontal position.
