Abstract
Apparatus for the display of time with a distinctive aesthetic character that includes clear, rigid rings rotating about a common axis which hang on wheels driven by a clockwork. The rigid rings each have demarcations that indicate the time of day. The time of day is interpreted using traditional clock interpretation means. A demarcation ring is added to assist in the interpretation of the indicated time.
Claims8
An apparatus for the display of time, comprising:
- (a) a clockwork, wherein said clockwork comprises an inner output shaft and an outer output shaft, wherein said inner output shaft and said outer output shaft are coaxial, wherein said inner output shaft and said outer output shaft are driven by said clockwork at unique angular rates, said inner output shaft having an end distal to said clockwork;
- (b) a first drive wheel driven by said inner output shaft;
- (c) a second drive wheel driven by said outer output shaft;
- (d) a first ring, wherein said first ring has a demarcation to represent the minute of the hour, wherein said first ring has an inner annular surface in contact with said first drive wheel, wherein said first ring hangs on said first drive wheel, wherein said first ring is held in contact with said first drive wheel by the force of gravity, wherein said first ring has an inner radius at least ten percent as large as the outer radius of said first ring, wherein said first ring inner radius is larger than a radius of said first drive wheel, wherein said first drive wheel is operable to rotate at a rate different than said first ring;
- and
- (e) a second rigid ring, wherein said second ring has a demarcation to represent the hour, wherein said second ring has an inner annular surface in contact with said second drive wheel, wherein said second ring hangs on said second drive wheel, wherein said second ring is held in contact with said second drive wheel by the force of gravity, wherein said second ring has an inner radius at least ten percent as large as the outer radius of said second ring, wherein said second ring inner radius is larger than a radius of said second drive wheel, wherein said second drive wheel is operable to rotate at a rate different than said second ring, wherein said second ring rotates about substantially the same rotational axis as said first ring,
- wherein said clockwork is operable to rotate said first ring 360 degrees once every hour and second ring 360 degrees once every twelve hours to allow the minute of the hour and the hour of the day to be interpreted using traditional clock interpretation means.
