Abstract

699,621. Supporting gramophone pick-ups. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 2, 1952 [Oct. 5, 1951], No. 24703/52. Class 40 (ii) In a gramophone, a pick-up arm unit is secured to the baseplate of the machine by magnetic means for the purpose of facilitating the changing of the pick-up for another type, such as would be required for use with micro-groove records, when different locations of the pedestal might be necessary. The pedestal may be provided with one or more magnets, and the baseplate wholly or locally of magnetic material, or vice versa. In the embodiment described, the base 3 contains an annular permanent magnet 7 and incorporates its own pick-up arm rest 9.
