Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
An illuminatable crystal comprising a transparent crystal for a dial, said crystal having an outer surface and an inner surface, means for producing a light mounted on said inner surface, a source of energy for said light-producing means, means for connecting the light to the source of energy and switch means operable from the outside the inner surface of said crystal for selectively connecting the source of energy to the light producing means, all three components being small compared to the total area of the crystal and being mounted along the periphery of the crystal.
Claim 2
Dependent Claim
95 words
An illuminatable crystal comprising a transparent crystal for a dial, said crystal having an outer surface and an inner surface, means for producing a light mounted on said inner surface, a source of energy for said light-producing means, means for connecting the light to the source of energy and switch means operable from the outside the inner surface of said crystal for selectively connecting the source of energy to the light producing means, all three components being small compared to the total area of the crystal and being mounted along the periphery of the crystal.
Claim 3
Dependent Claim
94 words
In combination with a crystal and with a dial, said crystal having an outer surface and an inner surface spaced from the dial, a frame mountable on the inner surface of said crystal, and means for producing a light, a source of energy for said light-producing means, means for connecting the light to the source of energy, and switch means operable from the outer surface of said crystal, and means for selectively connecting the source of energy to the light producing means mounted on said frame, all three components being mounted on said crystal.
Claim 4
Dependent Claim
94 words
In combination with a crystal and with a dial, said crystal having an outer surface and an inner surface spaced from the dial, a frame mountable on the inner surface of said crystal, and means for producing a light, a source of energy for said light-producing means, means for connecting the light to the source of energy, and switch means operable from the outer surface of said crystal, and means for selectively connecting the source of energy to the light producing means mounted on said frame, all three components being mounted on said crystal.
Claim 5
Dependent Claim
19 words
The combination of claim 2 further including means for mounting the frame on the inside surface of the crystal.
Claim 6
Dependent Claim
31 words
The illuminatable crystal of claim 1 wherein the means for electrically connecting the source of energy to the light-producing means is movable against a spring tension to make the electrical connection.
Claim 7
Dependent Claim
54 words
An illuminatable crystal as in claim 1 wherein said means for producing a light comprises a lamp, said source of energy comprises at least one battery, and said operable means comprises a button-type switch extending outwardly from the outer surface of the crystal and operable to connect the battery to the lamp when depressed.
Claim 8
Dependent Claim
143 words
An illuminatable crystal comprising a transparent crystal for a dial, said crystal having an outer surface and an inner surface, a peripheral flange integrally formed with the crystal projecting to one side with its outer edge terminating in a plane spaced from the inner surface of the dial, means for producing a light mounted on said inner surface of said crystal, a source of energy for said light-producing means, means for connecting the light to the source of energy and switch means operable from outside the inner surface of said crystal for selectively connecting the source of energy to the light-producing means, all three components being small compared to the total area of the crystal and being mounted along the periphery of the crystal in the space between the plane of the perimeter of the flange and the inner surface of the crystal.
Claim 9
Dependent Claim
143 words
An illuminatable crystal comprising a transparent crystal for a dial, said crystal having an outer surface and an inner surface, a peripheral flange integrally formed with the crystal projecting to one side with its outer edge terminating in a plane spaced from the inner surface of the dial, means for producing a light mounted on said inner surface of said crystal, a source of energy for said light-producing means, means for connecting the light to the source of energy and switch means operable from outside the inner surface of said crystal for selectively connecting the source of energy to the light-producing means, all three components being small compared to the total area of the crystal and being mounted along the periphery of the crystal in the space between the plane of the perimeter of the flange and the inner surface of the crystal.
