Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
A time indicating device comprising a circular disc having a clock dial face thereon said disc having a peripheral flange provided with a coaxial retaining groove spaced from said face in combination with an hour indicator disc rotatably mounted in said groove axially spaced from said face, including peripheral resilient means disposed between said discs whereby said means provides frictional resistance against inadverdant rotation, but not prevent necessary manual rotation of said time indicator disc and one of said discs is transparent.
Claim 2
Dependent Claim
82 words
A time indicating device comprising a circular disc having a clock dial face thereon said disc having a peripheral flange provided with a coaxial retaining groove spaced from said face in combination with an hour indicator disc rotatably mounted in said groove axially spaced from said face, including peripheral resilient means disposed between said discs whereby said means provides frictional resistance against inadverdant rotation, but not prevent necessary manual rotation of said time indicator disc and one of said discs is transparent.
Claim 3
Dependent Claim
80 words
A device as in claim 1 in further combination with a minute indicator disc mounted rotatably in a peripheral groove in said flange on the side of the device opposite the hour indicator disc, said minute indicator disc being spaced from said clock face disc by the resilient means similar to the resilient means between the first two said discs whereby both time indicator discs can be selectively rotated to various fixed positions, wherein two of said discs are transparent.
Claim 4
Dependent Claim
40 words
A device as in claim 2 further including additional locking means between said flange and said time indicator discs whereby manual compression of the discs against the resilient means releases said locking means for manual rotation of said indicator discs.
