Abstract

An hourglass timepiece that is filled with a plurality of precious or semi-precious stones, such as small uncut diamonds, which are suspended in a silicone compound, such as silicone oil, to prevent scratching of the interior surface of the hourglass as the stones move by gravity from an upper compartment to a lower compartment of the hourglass. The hourglass has similar ends, either of which can be supported by a decorative base that reflects light into the stones to highlight them and compensate for the reflective loss due to the silicone.

Claims

1. An hourglass time measuring device comprising

an hourglass shaped transparent body having a closed interior volume containing a plurality of small precious of semi-precious stones suspended in a liquid of sufficient viscosity to act as a lubricant between said stones and inner walls of said transparent body;

said liquid having a specific gravity less than that of said precious or semi-precious stones so said stones can fall by gravity to a bottom of said hour glass body;

said transparent body having first and second ends, each said end having an end plate thereover, said end plates being of similar shape and size;

a base for holding either of said end plates to support said transparent body in a generally vertical position so that said transparent body may be inverted with either end in a downward position on said base;

said base having a light reflecting exterior surface on at least a portion thereof and shaped to reflect light toward said precious or semi-precious stones in said transparent body.

2. The hourglass of claim 1 in which said precious or semi-precious stones are diamonds.

3. The hourglass of claim 2 in which said diamonds are uncut diamonds of approximately one-half karate in size.

4. The hourglass of claim 1 in which said transparent body comprises quartz glass.

5. The hourglass of claim 1 in which said liquid is a silicone.

6. The hourglass of claim 4 in which said silicone is a silicone oil.

7. The hourglass of claim 1 including a plurality of pillars extending between said end plate, said end plates being positioned to hold said end plates in fixed relation to each other, said pillars being equally circumferentially spaced apart around the transparent body.

8. The hourglass of claim 7 in which said pillars are elongated hollow tubular bodies.

9. The hourglass of claim 8 in which in at least one of the hollow tubular bodies is transparent and contains precious or semi-precious stones suspended in a liquid so they can move when the hourglass is inverted.

10. The hourglass of claim 9 in which said at least one hollow tubular body which contains precious or semi-precious stones has a liquid of a different viscosity than the viscosity of the liquid in the transparent body so that the stones therein descend at a rate different than the descent rate in the transparent body.

11. The hourglass of claim 10 in which the density of the stones and the density of the liquid is selected so the stones fall slowly downward when the hourglass is inverted.

12. The hourglass of claim 11 in which the density of the stones is relation to the density of the liquid is selected so a rate of descent of the stones in the hollow tubular body is greater than a rate of descent of the stones in the transparent body.

13. The hourglass of claim 11 in which the density of the stones in relation to the density of the liquid is selected so a rate of descent of the stones in the hollow tubular body is less than a rate of descent of the stones in the transparent body.

14. The hourglass of claim 7 in which the pillars are colored to accent and highlight said precious or semi-precious stones.

15. The hourglass of claim 14 in which the pillars are lighted from a power source in said base.

16. The hourglass of claim 1 in which an upper surface of said base is a light-reflecting surface and is concavely shaped to reflect light upwardly and toward the precious or semi-precious stones in the transparent body.

17. The hourglass of claim 16 in which at least an upper surface of the base comprises a silver colored metal.

18. An hourglass time measuring device comprising:

an hourglass shaped transparent body having a closed interior volume containing a plurality of uncut diamonds suspended in a dense liquid of sufficient viscosity to act as a lubricant between said diamonds and inner walls of said transparent body;

said transparent body having first and second ends, each end having an end plate thereover, said end plates being of similar size and shape;

a plurality of pillars extending between said end plates and secured thereto to hold said end plates in fixed relation to each other, said pillars being equally circumferentially spaced around the transparent body;

a base for holding either of said end plates to support said transparent body in a generally vertical position so that said transparent body may be inverted with either end in a downward position on said base;

said base having a light reflecting exterior surface on at least and upper portion thereof, said upper portion being concavely shaped to reflect light toward said uncut diamonds in said transparent body.

19. The hourglass of claim 18 in which at least one of said pillars is a hollow tubular body containing a second plurality of precious or semi-precious stones suspended in a liquid with the density of the stones in relation to the density of the liquid being selected so a rate of descent of the stones when the hour glass is inverted is greater than a rate of descent of the stones in the transparent body.

20. The hourglass of claim 18 in which at least one of said pillars is a hollow tubular body containing a plurality of precious or semi-precious stones suspended in a liquid with the density of the stones in relation to the density of the liquid being selected so a rate of descent of the stones when the hourglass is inverted is less than a rate of descent of the stones in the transparent body.

21. The hourglass of claim 18 in which a portion of said concavely shaped light reflecting surface has a plurality of indentations to concentrate reflection of a light on a specific portion of said precious or semi-precious stones.
