Abstract
611,553. Gramophone pick-ups. JACK & HEINTZ, Inc. May 1, 1946, No. 13148. Convention date, May 5, 1945. [Class 40 (ii)] [Also in Group XXXIX] In a gramophone pick-up the vibratory element is made in the form of a closed turn which vibrates transversely in the magnetic gap and links the core 4 to form the primary of an output transformer, the vibratory element being stiff in a vertical direction and flexible in a transverse direction. The vibratory element may have apart 26, Fig. 9, which is movable in a gap formed by the tip 27 of the magnet 2A and the tip 29 of the polepiece 28, or may have a double path 13, 14, Fig. 1 (not shown), in which both poles of the magnet are used. The stylus 24 may be gripped in a block of insulating material 23 by a screw 25. In an alternative construction, Fig. 4, the stylus 35 may be made with a threaded stem 34 which is screwed into a tapped cylinder 33 of insulating material,
