Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A gear changing system comprising a casing, an input shaft, a gear disc connected to said input shaft comprising a set of nine concentrically arranged gear wheels of different diameters, said gear wheels being provided with identical teeth with the number of said teeth on each of said gear wheels being a multiple of three, three additional shafts radially supported with respect to said gear disc and arranged at 120* with respect to each other, a sliding gear movable along each of said additional shafts for selective engagement with one of said gear wheels, an output shaft, transmission means to connect said sliding gears to said output shaft for adding the rotation of each of said sliding gears, alignment means on said disc, adjusting means on said disc, and abutment means on said casing whereby upon movement of said adjustment means against said abutment means said alignment means allows said sliding gears to be translated to another one of said gear wheels.
Claim 2
Dependent Claim
162 words
A gear changing system comprising a casing, an input shaft, a gear disc connected to said input shaft comprising a set of nine concentrically arranged gear wheels of different diameters, said gear wheels being provided with identical teeth with the number of said teeth on each of said gear wheels being a multiple of three, three additional shafts radially supported with respect to said gear disc and arranged at 120* with respect to each other, a sliding gear movable along each of said additional shafts for selective engagement with one of said gear wheels, an output shaft, transmission means to connect said sliding gears to said output shaft for adding the rotation of each of said sliding gears, alignment means on said disc, adjusting means on said disc, and abutment means on said casing whereby upon movement of said adjustment means against said abutment means said alignment means allows said sliding gears to be translated to another one of said gear wheels.
Claim 3
Dependent Claim
38 words
The system of claim 1 wherein said alignment means comprises three radial passages arranged at 120* with respect to each other, said passages being formed by aligning the spaces between two teeth on each of said gear wheels.
Claim 4
Dependent Claim
27 words
The system of claim 2 wherein said adjustment means comprises three radial arms arranged at 120* with respect to each other and extending beyond said gear disc.
Claim 5
Dependent Claim
21 words
The system of claim 3 and further comprising means for controlling the movement of said sliding gears on said additional shafts.
