Abstract

The clock designed to permit the time to be read from any direction, consists of a inner opaque member carrying time indicating figures, an outer transparent casing and hands of helical form. In one form of construction, the clock consists of an outer casing (1) of shaperical shape containing an inner sphere (2) carrying time indicating figures. An hour hand (4) and a minute hand (5) are each of helical form and driven by a clock mechanism contained withint the inner sphere. The inner sphere and casing are both stationary; the clock in other forms may have conical or cylindrical casing and inner members.
