Abstract

801,373. Automatic gramophones. ACKER, N. K. Dec. 14, 1955 [Dec. 15, 1954], No. 35849/55. Addition to 746,116. Class 40 (2). In a phonograph player as in the parent Specification an electric drive 61, 62 is coordinated with a system of selector switches 71 and relays 80, 90 which energize the solenoid 17 of an actuating member 117 to set the storing members 15. The disc 18 carrying the actuating member 117 is set in rotation by motor 61 upon the temporary closure of a switch 84 which operates relay 80 and establishes a hold-on circuit therethrough by means of a contact 81. As the disc 18 rotates, a spring contact thereon passes over contacts 64 on a disc 63 until circuit is completed through a pre-operated selector switch 71, whereby the relay 90 is operated and the solenoid 17 thereby energized to operate the member 117 and raise the storing member 15. The operation of relay 90 also breaks the hold-on circuit of the relay 80 and therefore the circuit of the motor 61. A modification is shown in Fig. 3 in which a smaller number of keys 71 are connected to flat selector contacts, the final selection being completed by the operation of one of the bank of keys 71 connected to the relay 90. It is also proposed to replace the keys 71 by a telephone calling dial.
