Abstract
369,729. Gramophones. BAMFORD, A. J., 82, Hanham Road, Kingswood, Bristol. Feb. 26, 1931, No. 6301. [Class 40 (ii).] A starting and stopping mechanism operable by the movement of the tone-arm comprises a brake block 5 adjustably mounted on a slide 4 movable in a casing 3 under the action of a spring 12 to apply the brake to the downwardly projecting rim 6 of the turntable, the slide being pushed back to release the brake by the movement of the tonearm 11 to the starting position A, Fig. 3, by a pivoted cam 7 with arms 8, 9 which is actuated by a pin 10a on an arm 10 adjustably fixed to the tone-arm. In moving the tone-arm to position A, the pin 10a rocks the pawl which is then moved by the slide so that the arm 9 comes against the end of the casing and the brake is off. The tone-arm is now placed on the record, and towards the end of playing, in position B, the pin 10a engages the arm 8 and rocks the pawl until at position C of the tonearm corresponding to the end of the record the slide, under the action of the spring 12, can rock the pawl and apply the brake.
