Abstract

Abstract A clock comprising, a case, a clockwork in the case having a plurality of pointers, a dial face in the case over which the pointers sweep about a common axis, a glass covering the dial and pointers, at least one illuminator for illuminating the dial and pointers and a ring having a face with spaced markings thereon which is mounted between the dial and glass and which can be manually rotated. The ring face is illuminated by the same illuminator which sheds light on the dial since the ring face faces the glass which receives light from the illuminator and illuminates both the dial and the ring face.

Dependent Claim 128 words
A clock comprising, a case, a clockwork mounted in said case having at least one rotatable pointer, a dial face in the case over which said at least one pointer sweeps about an axis, a glass connected to said case and covering said dial face and at least one pointer, at least one illuminator in the case for illuminating the dial face and at least one pointer, and a ring with a face carrying at least one marking rotatably mounted about the axis of said at least one pointer under said glass, said ring face facing said glass to be illuminated by said illuminator along with said dial face and at least one pointer, said ring face being conically inclined toward the axis and away from said glass.
Claim 3
Dependent Claim 147 words
A clock comprising, a case, a clockwork mounted in said case having at least one rotatable pointer, a dial face in the case over which said at least one pointer sweeps about an axis, a glass connected to said case and covering said dial face and at least one pointer, at least one illuminator in the case for illuminating the dial face and at least one pointer, and a ring with a face carrying at least one marking rotatably mounted about the axis of said at least one pointer under said glass, said ring face facing said glass to be illuminated by said illuminator along with said dial face and at least one pointer, said glass having a conical edge with said at least one illuminator arranged laterally of said conical edge of said glass, said conical edge inclined toward the axis and toward said dial face.
Claim 4
Dependent Claim 147 words
A clock comprising, a case, a clockwork mounted in said case having at least one rotatable pointer, a dial face in the case over which said at least one pointer sweeps about an axis, a glass connected to said case and covering said dial face and at least one pointer, at least one illuminator in the case for illuminating the dial face and at least one pointer, and a ring with a face carrying at least one marking rotatably mounted about the axis of said at least one pointer under said glass, said ring face facing said glass to be illuminated by said illuminator along with said dial face and at least one pointer, said glass having a conical edge with said at least one illuminator arranged laterally of said conical edge of said glass, said conical edge inclined toward the axis and toward said dial face.
Claim 5
Dependent Claim 42 words
A clock according to claim 1, wherein said glass has a roughened peripheral edge and flat surfaces, said illuminator positioned adjacent said peripheral edge to illuminate said surfaces to shed light on said dial face, at least one pointer and ring face.
Claim 6
Dependent Claim 33 words
A clock according to claim 1, including a dial carrying said dial face having an annular border portion, said ring rotatably mounted between said annular border portion of said dial and said glass.
Claim 7
Dependent Claim 24 words
A clock according to claim 4, wherein said dial border portion is offset toward said glass relative to a plane containing said dial face.
Claim 8
Dependent Claim 20 words
A clock according to claim 1, including setting means engaged with said ring for rotating said ring in said case.
Claim 9
Dependent Claim 43 words
A clock according to claim 6, wherein said setting means comprises a setting member rotatably mounted in said said case, a gear defined on a periphery of said ring and a gear connected to said setting member and meshed with said ring gear.
Claim 10
Dependent Claim 34 words
A clock according to claim 7, including one additional gear meshed between said ring gear and setting member gear so that manual rotation of said setting member rotates said ring in the same direction.
Claim 11
Dependent Claim 18 words
A clock according to claim 1, wherein said illuminator is provided at a lateral edge of said glass.
Claim 12
Dependent Claim 26 words
A clock according to claim 9, wherein said lateral edge of said glass is conically inclined toward said axis and toward an interior of said case.
Claim 13
Dependent Claim 49 words
A clock according to claim 7, including a sealing member around said setting member and a sealing ring between said case and a cover covering said case and supporting said glass, said sealing ring providing a space between said glass and said dial face for rotatably accommodating said ring.
Claim 14
Dependent Claim 25 words
A clock according to claim 1, wherein said case includes an outwardly projecting flange portion having at least one hole therethrough for mounting said clock.
Claim 15
Dependent Claim 153 words
A clock comprising, a case, a clockwork mounted in said case having at least one rotatable pointer, a dial face in the case over which said at least one pointer sweeps about an axis, a glass connected to said case and covering said dial face and at least one pointer, at least one illuminator in the case for illuminating the dial face and at least one pointer, a ring with a face carrying at least one marking rotatably mounted about the axis of said at least one pointer under said glass, said ring face facing said glass to be illuminated by said illuminator along with said dial face and at least one pointer, a setting member rotatably mounted in said case connected by gear means with said ring for rotating said ring in said case, and sealing means for sealing a space containing said ring and at least part of said gear means.
Claim 16
Dependent Claim 153 words
A clock comprising, a case, a clockwork mounted in said case having at least one rotatable pointer, a dial face in the case over which said at least one pointer sweeps about an axis, a glass connected to said case and covering said dial face and at least one pointer, at least one illuminator in the case for illuminating the dial face and at least one pointer, a ring with a face carrying at least one marking rotatably mounted about the axis of said at least one pointer under said glass, said ring face facing said glass to be illuminated by said illuminator along with said dial face and at least one pointer, a setting member rotatably mounted in said case connected by gear means with said ring for rotating said ring in said case, and sealing means for sealing a space containing said ring and at least part of said gear means.
