Abstract

198,685. RÚmy, A., Renaux, J., Delort, J., and Debrebant, F. June 1, 1922, [Convention date]. Driving; feed motions. -The turntable of a recording or reproducing machine employing disc records is traversed radially under the stylus and is rotated at a gradually increasing speed so that the linear speed of the sound trace remains constant. As shown, the turntable 6 is mounted on a framework sliding on horizontal bars 13, 22 and is traversed over a friction driving wheel 5 by a pinion 15 which is geared, by a worm 9, Fig. 4, and worm wheel 14, to the turntable spindle and engages a fixed rack 16. The stylus engages the record above the driving wheel 5. The rack 16 may be disengaged from the pinion when it is desired to rotate the turntable at constant angular speed for playing ordinary records. To enable this to be done the rack is hinged by means of a longitudinal spindle 17 provided with an external handle 18. The driving- wheel 5 is carried by a cranked lever 25 which is acted on by a spring 24 to press the wheel against the turntable.
