Abstract

602,734. Needle holders for sound-reproducing apparatus. O'BRIEN, W. J. Dec. 1, 1944, No. 24089. [Class 40 (iv)] [Also in Group XXXVIII] A needle holder for a needle-armature soundreproducing device, such as a gramophone pick-up, comprises a light-weight socket 10 of resilient material, in which the needle is a push fit, and a resilient junction piece between it and a fixed part of the pick-up. The junction piece extends from that side of the socket which is trailing with respect to the direction of travel of the record, and is arranged to be comparatively rigid in such direction. The bore of the needle holder extends right through so as to .facilitate withdrawal from the top of the pick-up where pressure is applied'to the pick-up against a resilient rest associated with a rigid abutment acting against the needle.
