Elapsed time clock

1. A clock comprising:

a body having a first clock face and a second clock face;

a start time assembly at least partially positioned within the body and corresponding with the first clock face;

an end time assembly at least partially positioned within the body and corresponding with the second clock face;

an elapsed time assembly in mechanical communication with both the start time assembly and the end time assembly; and the elapsed time assembly for determining the difference between a start time of the start time assembly and an end time of the end time assembly.

2. The clock of claim 1 , wherein the elapsed time assembly includes a dial with indicia thereon, and wherein adjusting one of the start time assembly or the end time assembly causes the dial to rotate.

3. The clock of claim 1 , further comprising a selector assembly, and wherein the selector assembly is moveable between a first configuration and a second configuration, wherein in the first configuration the elapsed time assembly is in mechanical communication with the start time assembly and not in mechanical communication with the end time assembly, and wherein in the second configuration the elapsed time assembly is in mechanical communication with the end time assembly and not in mechanical communication with the start time assembly.

4. The clock of claim 3 , wherein the end time assembly is locked in the first configuration.

5. The clock of claim 1 , wherein the start time assembly includes a digital display.

6. The clock of claim 1 , wherein the start time assembly is in mechanical communication with the elapsed time assembly by way of a gear train.

7. A clock comprising:

an elapsed time assembly including an elapsed time dial with indicia thereon;

a start time assembly in mechanical communication with the elapsed time assembly, the start time assembly having a first minute hand, and wherein clockwise movement of the first minute hand rotates the elapsed time dial in a first direction;

an end time assembly in mechanical communication with the elapsed time assembly, the end time assembly having a second minute hand, and wherein clockwise movement of the first minute hand rotates the elapsed time dial in a second direction opposite the first direction; and the elapsed time assembly for determining the difference between a start time of the start time assembly and an end time of the end time assembly.

8. The clock of claim 7 , further comprising a selector assembly, and wherein the selector assembly is moveable between a first configuration and a second configuration, wherein in the first configuration the elapsed time assembly is in mechanical communication with the start time assembly and not in mechanical communication with the end time assembly, and wherein in the second configuration the elapsed time assembly is in mechanical communication with the end time assembly and not in mechanical communication with the start time assembly.

9. The clock of claim 8 , wherein the second minute hand is locked from rotation in the first configuration.

10. The clock of claim 7 , wherein the start time assembly includes a digital display having a digital display dial with indicia thereon.

11. The clock of claim 10 , wherein rotation of the first minute hand causes the digital display dial to rotate.

12. The clock of claim 7 , further comprising a body having a first clock face proximate the first minute hand.

13. The clock of claim 12 , wherein the body includes a second clock face adjacent to the second minute hand.

14. The clock of claim 7 , wherein the first minute hand is in mechanical communication with the elapsed time dial by way of a first gear train.

15. The clock of claim 14 , wherein the second minute hand is in mechanical communication with the elapsed time dial by way of a second gear train.

16. The clock of claim 15 , wherein the elapsed time assembly further comprises an input gear, and wherein the input gear is moveable between a first position and a second position, wherein the input gear is meshed with the first gear train and not with the second gear train in the first position, and wherein the input gear is meshed with the second gear train and not the first gear train in the second position.

17. The clock of claim 16 , wherein the second minute hand is locked when the input gear is in the first position.

18. A clock comprising:

a body having a first clock face and a second clock face;

an elapsed time assembly including an elapsed time dial with indicia thereon;

a start time assembly in mechanical communication with the elapsed time assembly, the start time assembly having a first minute hand proximate the first clock face, and wherein clockwise movement of the first minute hand rotates the elapsed time dial in a first direction;

an end time assembly in mechanical communication with the elapsed time assembly, the end time assembly having a second minute hand proximate the second clock face, and wherein clockwise movement of the first minute hand rotates the elapsed time dial in a second direction opposite the first direction;

a start time digital display in mechanical communication with the start time assembly;

an end time digital display in mechanical communication with the end time assembly;

a selector assembly, the selector assembly moveable between a first configuration and a second configuration, wherein in the first configuration the elapsed time assembly is in mechanical communication with the start time assembly and not in mechanical communication with the end time assembly, and wherein in the second configuration the elapsed time assembly is in mechanical communication with the end time assembly and not in mechanical communication with the start time assembly; and the elapsed time assembly for determining the difference between a start time of the start time assembly and an end time of the end time assembly.
