发明名称 CLEANING OF GRAMOPHONE RECORDS
摘要 There is disclosed a gramophone pick-up attachment which comprises a first part attached to a pick-up cartridge or arm, a second part pivotally connected to the first part with a pivot axis which is substantially horizontal when the pick-up is in use, the second part carrying a record-cleaning device in the form of a brush for engagement with the playing surface of a record whilst it is being played, and a third part pivotally connected to the first part with a pivot axis which is substantially horizontal when the pick-up is in use, the third part carrying a record-cleaning device in the form of a pad for engagement with the playing surface of a record whilst it is being played. There are no springs engaging any of the first, second and third parts and the construction and arrangement of these three parts is such that the second part can pivot with respect to the first part about its pivot axis but its pivoting is limited in that it is prevented from pivoting so far in one direction that the part of the brush which contacts the record comes vertically below its pivot axis when the pick-up is in use and the third part can pivot with respect to the first part about its pivot axis but its pivoting is limited in that it is prevented from pivoting so far in one direction that the part of the pad which contacts the record comes vertically below its pivot axis when the pick-up is in use.
