Abstract

A record cleaning device which attaches to the tone arm of a record player for removing dust and other undesirable material from the grooves of a phonograph record without significant interferring with the normal tracking of the phonograph cartridge. The device includes a brush for brushing the undesirable material from the grooves of the phonograph record, and an elongated strip of thin, lightweight and flexible material for flexibly supporting the brush above and in contact with the grooves of the phonograph record in which the flexing action of the brush and that of the strip in relation to the brush weight allows for joint, commensurate and comparable flexing action of both during record playback. In a further embodiment a motion damper is mounted between the brush and the strip to stop energy exchange between them and to dampen feedback vibrations to the tone arm.

Dependent claims

Record cleaning apparatus comprising brush means for brushing undesirable material from the grooves of a phonograph record and having a predetermined flexibility when brought into contact with the record surface and suspension means for mounting said brush means to come in contact with the grooves of a phonograph record and pointed in a direction generally normal to its surface;

said suspension means comprising an elongated strip of thin, lightweight and flexible material, brush attachment means for attaching said brush means to one end of said elongated strip, and strip attachment means for attaching the other end of said elongated strip to the tone arm of a record player with the strip extending lengthwise beyond the end of the tone arm in a direction in alignment with a tangent to the record grooves so that the brush is held outwardly from and beyond the arm, whereat it is supported solely by said strip, said strip and said attachment means being constructed and arranged so that the flat sides of the strip are horizontal and the width of the strip are transverse to the record grooves and tone arm, said strip having a comparable flexibility to the brush so that the deflection of the brush at the record surface and the deflection of the strip respond in comparable manner so as to exchange deflection with each other in accommodation of record warp.
