Abstract

727,502. Gramophone pick-ups. PANNELL, D. Oct. 8, 1952, No. 25208/52. Class 40 (4). The armature 3 of a pick-up has a flattened end 7 which is inserted in a slot 10 with an interposed folded strip 8 of resilient material such as rubber or poly-iso-butelyne, the arrangement providing an armature seating which permits controlled vertical movements as well as lateral movements in the plane of the slot. The armature may be made from a tube of soft or Swedish iron and is fitted with a conical jewel or tungsten carbide stylus 5, while the slot is formed in a fixed plastic member 9 which may be made in two parts. An adhesive may be used to secure the resilient strip to both the flattened end and the slot, or alternatively the contacting surfaces of the latter parts may be roughened.
