Abstract

691,732. Supporting gramophone pick-ups. BRITISH BROADCASTING CORPORATION, PETRIE, R. D., and LOCKYER, J. S. Sept. 19, 1949 [Sept. 20, 1948], No. 24633/48. Class 40 (ii). A pick-up arm 11, Fig. 2, is attached to a carriage 12 supported by two pairs 17 of deepgroove ball-bearings arranged to run along a track rail 4. The facing surfaces of the outer races 18, Fig. 4, of the bearings are bevelled at 21 and engage the front and rear of the upper half of the rail 4, so as to be tilted by the wedging action of the rail to take up play in the bearings. The rail 4 is supported for rotation about its axis in ball-bearings 5, the heavy outer races 6 of which are resiliently supported by rubber diaphragms 9. The pick-up arm 11 carries an adjustable counterweight 14 which is engaged by an eccentricallymounted rod 22, rotatable by handle 24, to lift the pick-up 13 from the record surface.
