Abstract

638,481. Gramophones. MURPHY RADIO, Ltd., and BALEAN, J. H. June 5, 1945, No. 14154. [Class 40 (ii)] [Also in Group XXXIX] A gramophone pick-up (see Group XXXIX) is pivoted at 3 on the tracker arm 1 and a finger-piece 17 enables it to be lifted from the record. A sheet 15 of soft rubber or other plastic is held against the body by a perforated metal sheet 16. The stylus holder 14 projects through a pole on the plate 16 and in the sheet 15. The latter is turned down as at 18 to project beyond the stylus point, but yields under the weight of the pick-up and the drag of the record to allow the stylus to engage the record. Specification 638,482 is referred to.
