Abstract
Abstract A timepiece includes a casing which forms a part of the movement with the casing bottom forming the main part of the movement frame. The casing bottom is carved or formed in relief for receiving the elements of the movement and for supporting part of the shafts and gearing of the movement. The casing itself also includes two planar bearing surfaces. A bridge portion of the frame and the base plate of a regulating module is secured between the bearing surfaces in order to create a rigid frame for the assembly.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
A timepiece including in combination a casing forming a part of the movement frame with the casing bottom forming the main part of the movement frame, the casing bottom including a relief formed therein and adapted to the relief of the elements of the movement, said frame including first and second aligned bearing surfaces extending in a plane parallel to the plane of said casing bottom at a predetermined distance therefrom, a bridge secured to and extending between said first and second bearing surfaces, said bridge carrying at least a part of the gearing of the movement with said casing bottom supporting said gearing movement, said bridge maintaining the gearing in position between said casing bottom and said bridge, a removable self-contained regulating module including a base plate, said base plate extending between and secured to said bearing surfaces with the remaining module portions extending into said relief, said bridge base plate of said regulating module and casing forming a rigid movement frame when assembled.
Claim 2
Dependent Claim
165 words
A timepiece including in combination a casing forming a part of the movement frame with the casing bottom forming the main part of the movement frame, the casing bottom including a relief formed therein and adapted to the relief of the elements of the movement, said frame including first and second aligned bearing surfaces extending in a plane parallel to the plane of said casing bottom at a predetermined distance therefrom, a bridge secured to and extending between said first and second bearing surfaces, said bridge carrying at least a part of the gearing of the movement with said casing bottom supporting said gearing movement, said bridge maintaining the gearing in position between said casing bottom and said bridge, a removable self-contained regulating module including a base plate, said base plate extending between and secured to said bearing surfaces with the remaining module portions extending into said relief, said bridge base plate of said regulating module and casing forming a rigid movement frame when assembled.
Claim 3
Dependent Claim
113 words
The timepiece of claim 1 further including an aperture formed in said first bearing surface and an aperture formed in said base plate said apertures being in alignment when said base plate is mounted on said bearing surface, a screw having a frusto-conical bearing surface extending through said base plate aperture and secured in said bearing surface aperture, said screw being adapted to rotate said frusto-conical bearing surface bearing against said base plate of said regulating module in response to said rotation and producing a lateral displacement thereof for aligning said base plate with said bridge, said alignment determining the degree of interaction of the gearing of said movement and said regulating module.
