Abstract
Abstract The present invention relates to an electric timepiece with a driving regulator mechanism, the oscillations of which are electrically sustained by means of a transistorized circuit comprising at least two windings, i.e. a pickup winding and a driving winding. This timepiece is characterized by the fact that it comprises two winding carrying plates on each of which is secured one of these windings, one of the said plates carrying moreover the transistor or transistors as well as at least one part of the other elements of the sustaining circuit.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
In an electric timepiece with a driving regulator mechanism the oscillations of which are electrically sustained by means of a transistorized circuit comprising at least a pickup winding and a driving winding and including two winding carrying plates on each of which is secured one of the windings, one of the plates carrying moreover the transistor or transistors, as well as at least a part of the other elements of the sustaining circuit and a generator train driven by said mechanism, the improvement consisting of: each of the plates being secured on the frame of the clockwork by means of screws at least some of which additionally ensure an electrical connection, and said gear train comprising a gear formed of two elements idle with respect to one another and connected by a frictional coupling, wherein said coupling carries a substantially planar frame-shaped elastic plate embedded by one of its edges in a groove provided in the axial face of one of the elements, and acting, by its opposite edge, radially on a cylindrical shoulder of the other element.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
172 words
In an electric timepiece with a driving regulator mechanism, the oscillations of which are electrically sustained by means of a transistorized circuit comprising at least a pickup winding and a driving winding and including two winding carrying plates on each of which is secured one of the windings, one of the plates carrying moreover the transistor or transistors, as well as at least a part of the other elements of the sustaining circuit, with each of the plates being secured on the frame of the clock work by means of screws aT least some of which additionally ensure an electrical connection, the improvement consisting of: the driving regulator mechanism comprising a counting wheel pivoted between the baseplate and a clockwork bar, with the baseplate carrying a sleeve coaxial with the axis of the counting gear and directed towards the clockwork bar, and with the counting gear being freely engaged, and with the sleeve being intended to support the counting gear and prevent it from rocking upon the fitting of the clockwork bar.
