  • Patent number: 4810235
    Abstract: A variable transmission with an integral shifter, particularly suitable for a bicycle, having a variable-sprocket mounted on an axle having crank-arms. The variable-sprocket comprises a drive-flange and a indexing-flange, a pair of sprocket-segment-planets and at least a pair of idler-planets connected to the flanges, the planets adapted to expand and contract in response to a relative rotation of the flanges and thereby increase and decrease, respectively, the effective diameter of the variable-sprocket; and the sprocket-segment-planets are arranged along an imaginary line defined by the crank-arms.
    Type: Grant

  • Patent number: 4645475
    Abstract: An incrementally variable transmission, particularly suitable for a bicycle, having a variable-sprocket which comprises: A drive-flange and an indexing-flange mounted on an axle with a pair of sprocket-segment-planets and at least a pair of idler-planets sandwiched between the flanges, the planets adapted to expand and contract in response to a relative rotation of the flanges and thereby increase and decrease, respectively, the effective diameter of the variable-sprocket.

  • Patent number: 4521207
    Abstract: An incrementally variable transmission, particularly suitable for a bicycle, having a variable sprocket which comprises: A drive flange and an indexing flange mounted on an axle with a pair of sprocket-segment-planets and at least a pair of idler-planets sandwiched between said flanges and forming a relatively rigid structure, the planets adapted to expand and contract in response to a relative rotation of the flanges and thereby increase and decrease, respectively, the effective diameter of the variable-sprocket.

  • Patent number: 4493678
    Abstract: A variable sprocket, particularly suitable for a bicycle transmission, comprising a drive flange and an indexing flange mounted on an axle with a pair of sprocket-segment-planets and at least two idler-planets sandwiched between said flanges forming a relatively rigid variable-sprocket, the planets adapted to expand and contract in response to a relative rotation of the flanges and thereby change the effective diameter of the variable-sprocket.
