Variable-speed transmission device with positive action

A variable speed transmission device comprising:

• a first wheel having a front surface carrying a plurality of generally radially oriented bars thereon;
• a second wheel having a planar front surface spaced from and facing the front surface of said first wheel;
• a plurality of pegs;
• means for mounting said pegs in projection from said front surface of the first wheel in a circular configuration about the center of the first wheel to interact with said bars in a manner to translate rotation of one wheel into rotation of the other wheel, said mounting means holding said pegs against movement relative to said front surface of the second wheel parallel to said front surface thereof and permitting axial extension and retraction of said pegs in a direction perpendicular to the front surface of said second wheel;
• means for yieldably biasing said pegs to extend toward said front surface of the first wheel;
• and
• means for supporting said wheels with the front surfaces thereof in facing relation and in a manner permitting generally lateral movement of the wheels relative to one another to vary the transmission ratio.

A variable speed transmission device comprising:

• a first wheel having a front surface carrying a plurality of projecting pegs arranged in a circular configuration about the center of the first wheel;
• a second wheel having a front surface carrying a plurality of generally radially oriented bars thereon, each bar having a surface thereon operable to interact with the pegs in a manner to transmit rotation of one wheel into rotation of the other wheel;
• means for mounting said first and second wheels with said front surfaces thereof spaced apart and facing one another to effect interaction between said pegs and bars, said mounting means permitting relative lateral movement of said first and second wheels to vary the relative rotational speeds of the wheels;
• and
• said bars and pegs being arranged to permit interaction between each peg and each bar as the wheels rotate.

A variable speed transmission device comprising:

• a first wheel having a front surface carrying a plurality of projecting pegs arranged in a circular configuration about the center of the first wheel, each peg being rigidly connected with said front surface;
• a second wheel having a front surface carrying a plurality of flexible flaps projecting therefrom for interaction with said pegs, each flap having an edge operable to interact with said pegs to transmit rotation of one wheel into rotation of the other wheel and an inclined surface adapted to be contacted by the pegs to flex the flap toward said front surface of the second wheel to permit the pegs to pass the flaps;
• and
• means for mounting said first and second wheels with said front surfaces spaced apart and facing one another and in a manner permitting generally lateral movement of the wheels relative to one another to vary the relative rotational speed of the wheels.
