INTRODUCTORY SEXAGESIMAL TEACHING CLOCK

Abstract

The present invention relates to introductory teaching timepieces in general and specifically to a novel design applicable to watches and clocks whereby only the second hand is present and from which the minute and hour hands have been removed. The second hand moves in equally timed units such that one full cycle of its motion consists of 60 equally timed seconds. In doing so, it isolates the sexagesimal basis for time-telling so that the beginner can understand this numerical system prior to combining it with the duodecimal system used for minutes and hours.

Claims

1. An analog time telling device comprised of a second hand in motion over a timepiece face such that one full cycle of the second hand's movements depicts 60 seconds, with equally timed indica to represent each of the 60 seconds, and without the presence of either a minute or an hour hand.

2. The device of claim 1 wherein there are numerical indica for the hours.

3. The device of claim 1 wherein analog time is recreated in digital form.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0077] All the figures show a sample face of a timepiece with the second hand present and the hour and minute removed. These are nonetheless indicated with dashed lines to make it clear that a single hand is not intended to represent anything but the unit of a second and not minutes or hoursas is the case in U.S. Pat. No. 5,134,596, ANALOG TIMEPIECE WITH SINGLE HAND FOR DESIGNATING HOURS AND MINUTES.

[0080] FIG. 2Representational circular timepiece face with second hand only, Arabic numerals, and indica of 60 seconds presented as equally spaced lines inside the periphery of Arabic numerals. Absence of minute and hour hands indicated by dashed lines.

[0081] FIG. 3Representational circular timepiece face with second hand and implied hourly numerals and indica of 60 seconds presented as equally spaced shorts lines around the external periphery. Absence of minute and hour hands indicated by dashed lines.

[0082] FIG. 4Representational circular timepiece face with second hand only, Roman numerals, and indica of 60 seconds presented as equally spaced lines around the external periphery of the numerals. Absence of minute and hour hands indicated by dashed lines.
