CLOCK FOR KEEPING TIME AT A RATE OTHER THAN HUMAN TIME

RODNEY H. METTS & BARRY D. THOMAS
Patent No. 5,023,850

Patented June 11, 1991

CLAIMS:

1. A clock for keeping animal time, wherein animal time is defined as human time multiplied by a ratio given by the average lifespan of a human divided by the average lifespan of a type of animal whereby an animal second is equal to one human second divided by said ratio, one animal minute is equal to one human minute divided by said ratio, one animal hour is equal to one human hour divided by said ratio, and one animal day is equal to one human day divided by said ratio, said clock comprising:

a housing;
means for generating a reference frequency;
first means responsive to said generating means for producing pulses at a rate of sixty pulses per second times said ratio;
first clocking means for accumulating said pulses from said first producing means and producing an animal time output signal in animal hours, animal minutes and animal seconds;
second means responsive to said generating means for producing pulses at a rate of sixty pulses per second; and
second clocking means for accumulating said pulses from said second producing means and producing a human time output signal in human hours, human minutes and human seconds.

2. The clock as recited in claim 1, further comprising first display means responsive to said first clocking means for displaying said animal time output signal.

3. The clock as recited in claim 2, further comprising second display means responsive to said second clocking means for displaying said human time output signal.

4. The clock as recited in claim 2, further comprising first date means responsive to said first clocking means for keeping track of animal days and whereas said first display means displays an animal date as a number of said animal days in a year of arbitrary length.

5. The clock as recited in claim 1, further comprising first display means responsive to both said first clocking means and said second clocking means; and means for switching from said first clocking means to said second clocking means, said first display means displaying alternatively animal time and human time.

6. A clock for keeping animal time, wherein animal time is defined as human time multiplied by a ratio given by the average lifespan of a human divided by the average lifespan of a type of animal whereby an animal second is equal to one human second divided by said ratio, one animal minute is equal to one human minute divided by said ratio, one animal hour is equal to one human hour divided by said ratio, and one animal day is equal to one human day divided by said ratio, said clock comprising:

a housing;
means for generating a reference frequency;
first means responsive to said generating means for producing pulses at a rate of sixty pulses per second times said ratio;
first clocking means for accumulating said pulses from said first producing means and producing an animal time output signal in animal hours, animal minutes and animal seconds;
first display means responsive to said first clocking means for displaying said animal time output signal; and
means for varying said ratio to correspond to average life spans of different types of animals.

7. The clock as recited in claim 6, further comprising:

second means responsive to said generating means for producing pulses at a rate of sixty pulses per second; and
second clocking means for accumulating said pulses from said second producing means and producing a human time output signal in human hours, human minutes and human seconds.

8. The clock as recited in claim 6, wherein said ratio can be varied from 5.6 to 8.4.

14. In a women's shoe for use with replaceable heels of different height comprising:

an elongated sole having a forward support portion and a raised heel portion;
an insole superimposed over and secured to the sole;
a high heel registrable with said heel portion;
interlocking fastener means upon said high heel and heel portion removably anchoring said high heel to said heel portion;
said high heel upon disengagement of said fastener means adapted for removal and replacement by a low heel having similar fastener means;
each heel having an end face;
said interlocking fastener means including a plurality of interconnected spaced lock segments and spaced undercut lock flanges upon said heel portion and end face of the opposing heel respectively, adapted upon relative rotation from locked position through an acute angle for disengagement;
a retractable alignment pin in each heel, said alignment of the opposing heel being spaced from said lock segments nested within an alignment opening in said sole preventing said relative rotation;
said lock segments being mounted upon and secured to said heel portion and spaced therefrom with said lock flanges upon the opposing heel;
in one angular position of said opposing heel relative to said heel portion said segments being adapted for projection into corresponding slots in said opposing heel, and upon relative angular rotation adapted to interlock with said flanges;
the mounting of said lock segments including a heel anchor plate secured to said heel portion;
said lock segments depending from said anchor plate and projecting outwardly; and
a retractable anchor pin slidably mounted within said opposing heel in a lock position retainingly engaging said alignment pin in heel locking position;
and first spring means in each of said high heel and low heel, the first spring means of the opposing heel normally biasing said alignment pin toward a release position;
there being a clearance recess in said anchor pin, on manual retraction of said anchor pin said alignment pin moving into said recess.

15. In the women's shoe of claim 14 and second spring means in each of said high heel and low heel, the second spring means of the opposing heel normally biasing said anchor pin to an unlocked position.

16. A women's shoe for use with replaceable heels of different height comprising:

an elongated sole having a forward support portion and a raised heel portion;
an insole superimposed over and secured to the sole;
there being an elongated undercut central slot in said insole adjacent said sole;
an elongated flexible shank nested within said slot, at one end anchored to said sole and insole;
a high heel registrable with said heel portion;
interlocking fastener means upon said heel and heel portion removably anchoring said heel to said heel portion;
said high heel upon disengagement of said fastener means adapted for removal and replacement by a low heel having similar fastener means;
the replacement of the low heel shortening the distance between the anchoring of said shank and the end of said slot, with said shank moving longitudinally of said sole and insole within said slot.
