A cleaning mechanism for phonograph disc records includes a probe, and preferably a pluarality of probes arranged in line abreast relative to the direction of record rotation, for engagement within the record groove to remove particulate matter entrained therein. Previously cleaners have been brushes with fibres which inefficiently trail along the record surface. The probes maintain a bulldozing cleaning action and are preferably wire having a tip part inclined at about 90.degree. to a mounting part which is held in a carrier over the record. The carrier has means for dry cleaning such as a pad to pick up particles, or for wet cleaning including a liquid reservoir and dispensing means supported therefrom suitably from a pivoted arm. The carrier may be supported from a radially extending beam or a pivoted arm disposed in a leading attitude, in a manner permitting tracking by the probes of the record groove.
Cleaning mechanism for phonograph disc records, comprising a carrier, support means for positioning the carrier over a disc record groove when the latter is in operative location on a turntable and adapted to enable movement of the carrier in said operative location of the record in a direction generally towards the axis of rotation of the record, and a probe mounted on the carrier, said probe being a unitary element and generally rod-like and having a relatively stiff, hard wearing tip part which engages within the record groove at or substantially at the bottom of the groove, and a mounting part substantially longer than the tip part, extending from the tip part and supported on the carrier at a location remote from the tip part so as to impart flexibility to the mounting part, the mounting part and the tip part being mutually inclined so that, in operation, the mounting part is in a trailing attitude whilst the tip part is inclined at an acute angle relatively to the record with respect to the direction of travel of the point on the record engaged by the tip part, so as to maintain during rotation of the record a bulldozing action by the tip part to raise noise inducing particles out of the record groove, whilst the mounting part, through flexure thereof, enables the tip part to surmount obstructions in the groove.
