Phonograph record insulator

Claim 2

A pair of record insulators for covering the surfaces of a phonograph record, each of said record insulators having a hole at the center and an inner surface operable to contact one of the surfaces of the said phonograph record, and an outer surface opposite said inner surface, said inner surface comprising a layer of electrically-conductive material permanently affixed to the layer comprising the outer surface of the said record insulator, said layer of conductive material having an extended portion turned back and overlying the said outer surface layer at the periphery of the insulator, said record insulator being shaped and sized to fit the phonograph record, and having releasable mounting means engaging the perimeter of said record to temporarily maintain said insulator in place on said record, said mounting means affording removal of only the insulator of said pair covering the side of the record to be played, so that the other side of the said phonograph record can remain covered by the other of the pair of record insulators while playing the phonograph record on conventional phonograph record players.

Claim 3

A record insulator according to claim 1 comprising pressure-sensitive adhesive at the inner and outer perimeter of said inner surface and being of a substance such that said insulator can be temporarily sealed to the record on application of said record insulator thereto, and can be removed and reapplied several times without damaging either the record insulator or the said phonograph record.

Claim 4

A record insulator according to claim 1 characterized in that said record insulator is flexible so that it may be peeled from the record surface to release the temporary mount provided by said mounting means.

Claim 5

In the combination set forth in claim 1, wherein said layer of electrically-conductive material on the inner surface of the said record insulator is made of metallic foil and said mounting means position said foil in contact with the recorded surface of the said phonograph record to remove the electrostatic charges from the said recorded surface when said foil is grounded.

Claim 6

A record insulator according to claim 1 characterized in that the outer surface of the said record insulator is made of non-porous, easily cleanable, water and damp-proof material to protect the surfaces of the phonograph record from exposure to dust, oil, and other materials.

Claim 7

A record insulator according to claim 1 characterized in that the outer surface of the said record insulator is of a material which may be used for printing information thereon.

Claim 8

A pair of record insulators for covering the surfaces of a phonograph record, each record insulator having a hole at the center and an inner surface operable to contact one of the surfaces of the said phonograph record, and an outer surface opposite said inner surface, said outer surface comprising a layer of non-porous, easily cleanable, water and damp-proof material, having spacers along its outer and inner perimeter, whereby spacing between the records is increased, said record insulators being shaped and sized to fit the phonograph record, and having releasable mounting means engaging the perimeter of said record to temporarily maintain each of said pair of insulators in place on one of the sides of said record, said mounting means affording removal of only the insulator of said pair covering the side of the record to be played, so that the other side of the said phonograph record can remain covered by the other of the pair of record insulators while playing the phonograph record on conventional phonograph record players.

Claim 9

A pair of record insulators for covering the surfaces of a phonograph record, each record insulator having a hole at the center and an inner surface operable to contact one of the surfaces of the said phonograph record, and an outer surface opposite said inner surface, said outer surface comprising a layer of non-porous, easily cleanable, water and damp-proof material, having spacers along its outer and inner perimeter, whereby spacing between the records is increased, said record insulators being shaped and sized to fit the phonograph record, and having releasable mounting means engaging the perimeter of said record to temporarily maintain each of said pair of insulators in place on one of the sides of said record, said mounting means affording removal of only the insulator of said pair covering the side of the record to be played, so that the other side of the said phonograph record can remain covered by the other of the pair of record insulators while playing the phonograph record on conventional phonograph record players.

Claim 10

A record insulator for covering a surface of a phonograph record having a central hole, an inner periphery surrounding said hole, an outer periphery spaced from said inner periphery, and a playing surface between said inner and outer peripheries, said record insulator having an outer periphery, a hole at the center to define an inner periphery and an inner surface layer operable to contact the playing surface of the said phonograph record, and an outer surface layer opposite said inner surface, said inner surface layer comprising electrically-conductive material permanently affixed to the outer layer of the said record insulator, said layer of conductive material having an extended portion turned back and overlying the said outer surface layer at one of the peripheries of the insulator, and spacer elements on the outer surface of said insulator confined to the inner and outer peripheries of the insulator so as to overlie the inner and outer perimeter of said record to increase the separation between the playing surface of the record and a succeeding record placed on top of said insulator, said record insulator being shaped and sized to fit the phonograph record, and having releasable mounting means engaging the perimeter of said record to temporarily maintain said insulator in place on said record.

Claim 11

A record insulator for covering a surface of a phonograph record having a central hole, an inner periphery surrounding said hole, an outer periphery spaced from said inner periphery, and a playing surface between said inner and outer peripheries, said record insulator having an outer periphery, a hole at the center to define an inner periphery and an inner surface layer operable to contact the playing surface of the said phonograph record, and an outer surface layer opposite said inner surface, said inner surface layer comprising electrically-conductive material permanently affixed to the outer layer of the said record insulator, said layer of conductive material having an extended portion turned back and overlying the said outer surface layer at one of the peripheries of the insulator, and spacer elements on the outer surface of said insulator confined to the inner and outer peripheries of the insulator so as to overlie the inner and outer perimeter of said record to increase the separation between the playing surface of the record and a succeeding record placed on top of said insulator, said record insulator being shaped and sized to fit the phonograph record, and having releasable mounting means engaging the perimeter of said record to temporarily maintain said insulator in place on said record.
