Abstract
A timepiece is provided in the form of a body having a face which displays a sinusoidal path of multiples of twelve wavelengths within a circular periphery, and concentric rings on the face which intersect the path. An arm rotates about the center of the face a rate of one revolution per every twelve hours. A time-indicating pointer, mounted for guided longitudinal movement with respect to the arm, reciprocates with respect to the arm at one cycle per hour. The combined rotation of the arm and reciprocation of the pointer cause the pointer to follow the sinusoidal path, such that the pointer indicates hours by its circumferential position relative to the crests of the wavelengths and indicates minutes by its radial position relative to the concentric rings.
Claims6
A timepiece comprising:
- a body having a face displaying a sinusoidal path of multiples of twelve wavelengths within a circular periphery, and concentric rings intersecting the path;
- a clocking mechanism mounted on the body having an output shaft arranged centrally with respect to the sinusoidal path;
- an arm mounted for rotation about the output shaft and extending radially from it;
- means connecting the output shaft to the arm for inducing stepped-down rotation of the arm about the output shaft, whereby 13/12 revolutions of the output shaft define one hour and one revolution of the arm defines multiples of twelve hours;
- a pointer mounted for guided longitudinal movement with respect to the arm;
- means connecting the output shaft to the pointer for inducing reciprocating motion of the pointer with respect to the arm causing the pointer to track the sinusoidal path upon rotation of the output shaft, whereby the pointer indicates hours by its circumferential position relative to the crests of the wavelengths and indicates minutes by its radial position relative to the concentric rings.
