Patent DE-3036165-A1 (DE)
Inventor: KLINGENBERG HANS ULRICH
IPC: G04B19/04
Filed: 1980-09-25
Abstract: Instead of conventional hands, an hour disc and a minute disc are provided. The hands are represented by markers vaporized upon the undersides of the discs. The discs are pivoted on an arbor anchored in the watch glass. This arbor is hollow, and inserted in the free end thereof is a rivet-shaped retaining part which keeps the discs from slipping off the arbor. Each disc is toothed at its circumference. The teeth of the minute disc engage a gear wheel having a pinion which meshes with the teeth of the hour disc. This wheel and pinion are mounted on an arbor, one end of which is anchored in the watch glass. A retaining ring prevents the wheel from becoming detached from the arbor. This gear wheel likewise engages a pinion of another gear wheel mounted on an arbor. One end of this arbor is also anchored in the watch glass. A pinion of a stepping motor meshes with the teeth of the further gear wheel. The yoke of the stepping motor is rigidly connected to the watch glass by means of bolts which likewise have one end anchored in the watch glass. A shaft bearing the pinion and the rotor of the stepping motor is pivoted at one end in a recess in the watch glass. Because all the parts necessary for driving the discs, as well as the discs themselves, are either fixed to the watch glass or pivoted about arbors anchored in the watch glass, plates can be dispensed with, so that manufacture of the timepiece is considerably simplified.
