Abstract

345,796. Coin-freed gramophone apparatus. McINTOSH, J. A., 331, Sauchiehall Street, Glasgow. March 8, 1930. No. 7609. [Class 27.] Coin action, weight.- Relates to coin - freed mechanism for gramophones in which a coin closes momentarily by weight a switch 3 to energize an electromagnet 4, the armature 7 of which is attracted to close a switch' 5 in the circuit of the electric motor 6 driving the gramophone. The armature is retained in its attracted position by a trip device which is released by the tone-arm when the playing of a record is finished. According to the invention the trip comprises a counterweighted lever 9, 10, the arm 10 having a toe 12 which moves in a clockwise direction to engage the top of a ridge 13 on the armature 7 when this is momentarily attracted and retains the armature against the action of a spring 8. The switch 5 is thereby held closed until a cam 14 moving with the tone-arm engages the arm 9 of the trip lever to move the toe 12 in a counterclockwise direction off the ridge 13 and allow the armature to return to its initial position.
