Abstract
A global time indicating calculator has a rotating dial for calculating global standard time and advanced time in various international time zones. Indicia printed on the face of the dial and corresponding sections of the face of the calculator can be easily referenced to determine time of day at selected locations throughout the world. The calculator is used by dialing present time and reading the indicia to determine time at a different local. The dial has an outer annular ring marked with numerical indicia and scale indicia along its circumference for measuring time at selected increments. The time indicia is matched with selected geographical region to calculate the time of day worldwide.
Claims15
A device to calculate local time in different geographical regions of the world comprising:
- a generally flat front wall joined to a generally flat back wall, a rotatable member layered between the front and back walls, the rotatable member having an outer annular edge and a centrally located generally circular outwardly projecting hub having a generally flat outer surface, time indicia indicating a 24-hour period of time located on the outer surface of the hub, the front wall having a flat outer surface substantially flush with the outer surface of the hub and a generally circular opening accommodating the hub and exposing the time indicia, line indicia located on the outer, surface of the front wall forming a plurality of generally rectangular vertically disposed sections adjacent the hub, each section representing a geographical region within which a uniform time is used, the section containing horizontally disposed printed matter identifying localities within the geographical region, and groove means in the front and back walls exposing a portion of the outer annular edge of the rotatable member for manual rotation of the rotatable member, the rotatable member manually rotatable in opposite directions to selectively move time indicia representing the time of day at a selected locality adjacent the section representing the geographical region of the selected locality whereby the time of day of one or more other localities designated by the printed matter located in another section can be determined, and means for aligning the time indicia with each section.
A device to calculate local time in different geographical regions of the world comprising:
- a front wall having a centrally located opening, a rotatable member located adjacent the front wall, the rotatable member having time indicia representing the time of day visible through the opening indicating first and second 12-hour periods of time, the front wall having line indicia forming first and second columns of vertically disposed generally rectangular shaped boxes on opposite sides of the front wall, each box representing a geographical region within which a uniform time is recognized, horizontally disposed printed matter located in the box identifying localities within the geographical region, the rotatable member movable to move time indicia for a selected time of day of a selected locality adjacent the box representing the geographical region of the selected locality whereby the time of day of one or more other localities designated by the printed matter located in another box can be determined.
A manually operated global time indicating device for calculating international time comprising:
- a generally flat first wall joined to a generally flat second wall, a generally circular member rotatably mounted in sliding engagement with the first and second walls, the circular member having a centrally located outwardly projecting hub, the first wall having an opening accommodating the hub, the hub having an outer annular surface bearing against an annular surface surrounding the opening to hold the circular member in assembled relation, the first wall having line indicia forming first and second columns of vertically disposed generally rectangular shaped boxes on opposite sides of the front wall, each box representing a geographical region within which a uniform time is recognized, printed matter contained within the box identifying localities within the geographical region, the circular member movable to move time indicia printed on the outer face of the hub adjacent the box whereby the time of day of other localities identified by the printed matter contained within another box can be determined.
