Abstract

355,621. Gramophones. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel. Eindhoven, Holland. Dec. 15, 1930, No. 37790. Convention date, Jan. 11. [Class 40 (ii).] Records are adapted to be centred on the spindle 1 of a gramophone turntable 2 by engaging a tapering body 6 which is resiliently movable in the direction of the spindle axis and co-operates with a tapered recess in the boss of the turntable, the arrangement being that owing to the weight of the record the said body is moved axially to such an extent that the record will bear on the turntable. The turntable 2 is fixed to the motor spindle, and the tapering body 6 is provided with a pin 5 which is supported on a spring 4 in an axial cavity 3 in the spindle 1. The upward movement of the pin 5 is checked by a screw 9 which projects into the axial cavity 3 and engages a recess 7 in the pin.
