Fig. 1 shows an elevation, and Fig. 2 an end view, of the apparatus. A suitable motor is provided with a shaft 5 having at one end a feed-screw 34, and at the other a bevel-wheel 7. The wheel 7 gears with a similar wheel 8 fixed to the vertical sleeve axle 10. The sleeve 10 has a spring pin 13 engaging by pin and slot, and provided on its upper end with a grooved cone 14 on which the record fits. The record is formed of a corrugated metal disc 30, having papier-mÔchÚ record rings 31 cemented on one or both sides. The reproducer- 40, Fig. 2, is held in a preferably jointed arm 39 mounted to slide on a rod 38, and having a depending arm 36 carrying a partial nut 35 and extension 43, The extension 43 is provided with a friction roller 45, which runs in one or other of the grooves 47, 47a on an eccentric guide-cylinder. The record is kept up against the stylus by means of a roller 24 on a pivoted shaft 22 provided with an adjusting-screw 26 and spring 29. These adjustments are mounted on the eccentricallypivoted table 21.
