Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
56 words
A timepiece comprising, a casing with a bearing surface element, a movement and frame therefor, a motor spring and a barrel surrounding the spring, the barrel being open on both ends, the barrel including a ring rotatably mounted on the bearing surface such that the side of the barrel facing the bearing surface is closed thereby.
Claim 2
Dependent Claim
56 words
A timepiece comprising, a casing with a bearing surface element, a movement and frame therefor, a motor spring and a barrel surrounding the spring, the barrel being open on both ends, the barrel including a ring rotatably mounted on the bearing surface such that the side of the barrel facing the bearing surface is closed thereby.
Claim 3
Dependent Claim
27 words
A timepiece as claimed in claim 1 including a winding train and pinion associated therewith, said barrel having an outer toothing for meshing engagement with said pinion.
Claim 4
Dependent Claim
38 words
A timepiece as claimed in claim 1 in which the movement includes a gearing with gearing elements, the barrel having a shaft, a wheel carried on said shaft, the wheel being the first element of the movement gearing.
Claim 5
Dependent Claim
37 words
A timepiece as claimed in claim 1 in which the bearing surface element includes an annular recess with a central upstanding embossment and the ring is partially mounted in the recess for rotatable movement around said recess.
Claim 6
Dependent Claim
35 words
A timepiece as claimed in claim 1 in which the bearing surface element is formed as a circular recess with a lateral wall and the ring is partially engaged and rotatably mounted in the recess.
Claim 7
Dependent Claim
64 words
A timepiece as claimed in claim 5 in which the movement includes a gearing with gearing elements, the barrel having a shaft, the timepiece including a second frame element, the barrel shaft being rotatably mounted between the bearing surface element and the second frame element, and a retaining wheel carried by the barrel shaft to prevent the ring from leaving the bearing surface element.
Claim 8
Dependent Claim
53 words
A timepiece as claimed in claim 5 including a winding train and pinion associated therewith, said barrel having an outer toothing for meshing engagement with said pinion, an annular member secured to the movement frame, said annular member surrounding the ring and forming an axial abutment for the outer toothing of the barrel.
Claim 9
Dependent Claim
55 words
A timepiece as claimed in claim 5 including a winding train and pinion associated therewith, said barrel having an outer toothing for meshing engagement with said pinion, said outer toothing extending substantially the entire height of the ring and being partially engaged in the circular recess and cooperating with the lateral wall of said recess.
