Abstract

1,036,431. Gramophone pick-ups. W. WORDEN. Feb. 6, 1963 [Feb. 7, 1962], No. 4782/62. Heading G5R. The light wooden arm members 16a, 16b are pivoted together and one end of 16a is pivoted on a trunnion 18 and carries an upright ball bearing 31, Fig. 5, by which the portion 16b is supported. The bearing 31 is offset to the side of the arm nearer to the turntable centre and the movement of the member 16b is regulated by an adjustable link 54 connected to the arm at 55 and anchored to a fixed pivot at 57. The link 54 is disposed on the side of the bearing 31 farther from the turntable centre and is also slightly offset towards the support 18 relative to the keying 31. A numerical example of the linkage is worked out in connection with Fig. 3 (not shown) and results in a maximum tracking error of “ degree. The trunnion blocks 18 are of wood and may be changed to set up the desired original settings.
