Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 91 words
Means for mounting a centrally apertured phonograph turntable upon a phonograph, said means comprising a turntable shaft; a substantially cylindrical clip of generally C-shaped cross section adapted to telescope over said shaft; said clip having a plurality of radially outwardly offset tension means spaced around the circumference thereof; said tension means adapted to resiliently contact surface portions of the turntable aperture when the turntable is mounted on the shaft and afford a reactive force inwardly against the shaft whereby the turntable is firmly mounted and centered with respect to said shaft.
Claim 2
Dependent Claim 91 words
Means for mounting a centrally apertured phonograph turntable upon a phonograph, said means comprising a turntable shaft; a substantially cylindrical clip of generally C-shaped cross section adapted to telescope over said shaft; said clip having a plurality of radially outwardly offset tension means spaced around the circumference thereof; said tension means adapted to resiliently contact surface portions of the turntable aperture when the turntable is mounted on the shaft and afford a reactive force inwardly against the shaft whereby the turntable is firmly mounted and centered with respect to said shaft.
Claim 3
Dependent Claim 19 words
Means for mounting a turntable as set forth in claim 1; said tension means comprising axially parallel, resilient ribs.
Claim 4
Dependent Claim 39 words
Means for mounting a turntable as set forth in claim 2; said clip being formed of a single piece of sheet spring metal; said clip comprising a substantially cylindrical body and said ribs being struck outwardly from said body.
Claim 5
Dependent Claim 54 words
Means for mounting a turntable as set forth in claim 2; said clip being formed of a single piece of sheet spring metal; said clip comprising a substantially cylindrical body; said body having a plurality of pairs of circumferentially spaced slots; the metal disposed between said slots being struck outwardly to form said ribs.
Claim 6
Dependent Claim 63 words
Means for mounting a turntable as set forth in claim 1; said shaft having a diametrically reduced portion disposed between a pair of radially outwardly projecting, annular shoulders; said clip engaging said reduced portion in use thereof and being retained against axial displacement by said shoulders whereby a turntable can be seated upon and removed from said shaft without removal of said clip.
Claim 7
Dependent Claim 143 words
A turntable-retaining clip for a phonograph adapted to be disposed between a turntable shaft and the central opening of a turntable, said clip being formed about an axis from a single piece of sheet spring metal into a substantial cylinder having circumferentially spaced edges; said clip having a plurality of pairs of circumferentially spaced elongated slots disposed parallel with the axis of said clip; the metal disposed between said slots being struck radially outwardly and forming axially parallel, resilient tension ribs; said ribs adapted to resiliently contact surface portions of the turntable opening when the turntable is mounted on the shaft And afford a reactive force inwardly against the shaft whereby the turntable is mounted and centered with respect to the shaft and whereby the turntable can be readily removed from the shaft by manual pressure on said turntable in an axial direction.
Claim 8
Dependent Claim 143 words
A turntable-retaining clip for a phonograph adapted to be disposed between a turntable shaft and the central opening of a turntable, said clip being formed about an axis from a single piece of sheet spring metal into a substantial cylinder having circumferentially spaced edges; said clip having a plurality of pairs of circumferentially spaced elongated slots disposed parallel with the axis of said clip; the metal disposed between said slots being struck radially outwardly and forming axially parallel, resilient tension ribs; said ribs adapted to resiliently contact surface portions of the turntable opening when the turntable is mounted on the shaft And afford a reactive force inwardly against the shaft whereby the turntable is mounted and centered with respect to the shaft and whereby the turntable can be readily removed from the shaft by manual pressure on said turntable in an axial direction.
