Abstract: 10,779. Carter, H. J. May 18. Phonographic apparatus ; actuating-mechanism.-In magazine phonographs in which a circular frame carries a number of cylindrical records on its periphery, the rotation of an external handle is adapted to wind up the driving- weight 18, Fig. 1, and to set the frame 1 by the aid of a pointer 4 to bring any chosen record 55 into position beneath the reproducer 29 ; mechanism is also provided for effecting a quick k return of the reproducer carriage 27. The operator rotates a handle, thereby winding up the weight 18 on a drum 17 through gearing 13, 14, 15, Fig. 8, and simultaneously, through gearing 15, 16, rotating a screwed spindle 19. A nut 20 traverses the screw, and, at the completion of the winding, the pivot pin of a spring-controlled lever 22, which is mounted on the nut, raises a locking-lever (not shown) from engagement with a pin 23 on a clutch arm 11, permitting the lever 22 to move the arm from engagement with a sector 12 on the gear 13 and to throw it into engagement with a pulley 8, which carries a cord 8<a>, Fig. 1, passing round a pulley carriage 8<b> and the frame 1. The operator continues to rotate the handle until the required record is positioned. The governor of the driving train having been freed by prepayment, the weight 18 descends and drives the screws 25, 26 which are geared together, and, a knife-edge 33 on the carriage 27 being in engagement with the coarse thread 26, the carriage rapidly completes its return movement along the rod 24. A cam 37 then engages one extremity of a spring-pressed rod, which is carried by the carriage, rocking the carriage and spindle 24, lifting the knife-edge 33 from the screw 26, and throwing a sector 32 into engagement with the fine scraw 25, the carriage then commencing its return, the re producer 29 having been simultaneously lowered into engagement with the record. The abovementioned rocking of the spindle 24 throws a fork 35, Fig. 2, into locking engagement with a pin 58 on the frame. and allows a wheel 41 driven through a belt 42 to drop into engagement with a wheel 43 on the record. At the completion of the travel of the carriage, a cam 36 depresses the carriage on to the screw 26, a pin 44 on the fork 35 lifting the wheel 41 out of gear, and a pawl 59 slightly rotating the frame 1 to move the record out of position. Weights 57 are attached to the numbers 3 of the records to retain them in a vertical position. The tubes connecting the reproducer to the trumpet are arranged to telescope and are formed with ball- and-socket joints. Coin action; coin-di8charging mechanism. - The coin depresses a counterweighted lever 48, Fig. 2, thereby removing a detent 49 from the governor 50 of the driving train, the lever depressing and passing under a pivoted arm 51 on a spring-controlled spindle 52, the coin then falling out of the pan. An arm 53 on the carriage 27 engages an arm 52<a> on the spindle 52, rocking that spindle and permitting the arm lever to escape past the arm 51 and finally past a second arm 51<a>, when it again engages the governor.
