Abstract

19,667. Kramer, E. April 29, [Convention date]. Driving and stopping.- In talking-machines for dictating, of either the disk or cylinder record type, there is interposed a spring coupling between a fly-wheel 2 on the motor spindle 1 and the turntable 5, whereby the turntable is rapidly stopped and started. A loose sleeve 3 on the spindle 1 is attached rigidly to the turntable 5 by a nut 4, mounted on the sleeve 3 by a pin 7 working in a vertical slot 8 is a clutch disk 6 having rings 10, 11 of leather or india-rubber, adapted to engage either with the fly-wheel 2 or against a simnar ring 13 on a plate 14 fixed to the cabinet 15. A spring 9 tends to hold the clutch disk 6 in contact with the fly-wheel 2. To raise the clutch disk 6 to stop the turntable 5, a bifurcated lever 17, pivoted at 18 and engaging a flange 16 on the clutch disk 6, is raised by a hand-operated cam lever 22.
