Clock

A large-sized clock comprising:

• a face having a plurality of time-indicating numbers,
• a stationary shaft disposed centrally of said face;
• a minute hand mounted for rotation about said shaft and including a tail end and a leading end, said leading end being spaced farther from said shaft than said tail end, said minute hand being hollow and forming a minute-hand tail space between said shaft and said tail end;
• an hour hand mounted for rotation about said shaft and including a tail end and a leading end, the latter being spaced farther from said shaft than the former, said hour hand being hollow and forming an hour-hand tail space between said shaft and said tail end of said hour hand;
• a first drive means for driving said minute hand comprising an electric motor and a first gearing mounted to said minute hand and disposed in said minute-hand tail space, said electric motor rotating said first gearing, said first gearing meshing with teeth connected to said stationary shaft so that rotation of said first gearing causes said minute hand to rotate about said stationary shaft;
• a second drive means for driving said hour hand comprising:
• a rotary shaft mounted for rotation about said stationary shaft and connected to said minute hand for rotation therewith, said rotary shaft including a portion extending into said hour hand, and
• a second gearing mounted to said hour hand and disposed in said hour-hand tail space, said second gearing being operably connected to said section of said rotary shaft to rotate said hour hand in response to rotation of said minute hand;
• control means mounted in said minute-hand tail space and operably connected to said electric motor for controlling the operation thereof, and
• a storage cell type electric power source disposed within said minute-hand tail space and operably connected to said electric motor and said control means for providing electric power thereto.
