Abstract

19,589. Hoffay, J. Aug. 29. Tool arms and mountings; tone-arm joints.- -For playing variously-cut records and with the soundbox parallel with or transverse to the groove, the sound-box is provided with a number of styli mounted in radial directions at different peripheral points and connected to the centre of the diaphragm by one or more members. In the form shown in Fig. 1, a steel needle 10, a diamond 11, and a sapphire 12 are mounted on one boss 20 pivoted at 21. In another construction, they are mounted separately, and are equally spaced at sufficient distance to permit any stylus to be used with any kind of record. An indicator 31 may be mounted on the tone-arm, with a screw or spring detent to engage in recesses 34, 35 in a groove on the sound-box boss, to facilitate the setting of the sound-box in selecting a stylus. The coupling between the sound-box and tone-arm, enabling the sound-box to be placed in either the parallel or the transverse position relative to the groove, may be as described in Specification 1950/14.
