Electrostatic-vacuum record cleaning appts. - uses air blower adjacent to charging device to aid dislodgement of dust particles

摘要

Appts. uses a turntable on which the record is supported and rotated beneath a charging mechanism that imparts an electrostatic charge, causing dust particles on the playing surface to be loosened. A vacuum device, supported above the playing surface adjacent the charging device, causes the loosened particles to be removed and carried away by air movement. To aid in dislodging the dust particles, it is advantageous to employ an air blower located adjacent the charging device. An attraction member, charged oppositely to the particles, can pull the particles away from the record and toward the vacuum. An additional conductor to which an alternating current is applied can be employed to remove any residual charge from the record, thereby preventing additional dust particles from being attracted to the record.
