Infinite speed transmission

A device comprising:

• a cone and a cylinder having axes in a common plane, said cone and said cylinder intersecting said common plane on two parallel lines,
• a power transfer element chosen from the group consisting of substantially rigid rings and substantially flexible belts, said power transfer element encompassing said cylinder, said power transfer element being approximately as thick as the distance between said parallel lines and said power transfer element being nipped between said cone and said cylinder,
• a controlling mechanism capable of applying lateral pressure on said power transfer element, said controlling mechanism moving back and forth on a line substantially parallel to said parallel lines,
• whereby such device constitutes a continuously variable transmission.

A device comprising:

• a cone and a cylinder having axes in a common plane, said cone and said cylinder intersecting said common plane on two parallel lines said cylinder having lengthwise grooves such that said cylinder is a wide gear,
• a power transfer element, said power transfer element being a substantially rigid ring encompassing said cylinder, said ring having gear teeth on the inside meshing distinctly with said grooves of said cylinder, said ring being nipped between said cone and said cylinder and having friction contact with said cone,
• a controlling mechanism capable of applying lateral pressure on said ring, said controlling mechanism moving back and forth on a line substantially parallel to said parallel lines,
• whereby said device constitutes a continuously variable transmission with a geared contact on said cylinder and a friction contact on said cone.
