Multiratio power transmitting device

A multiratio drive comprising:

• a. a drive plate mounted for rotation about an axis and means for drivingly coupling said drive plate to a source of motive power,
• b. an even numbered plurality of driven elements mounted to said drive plate for sliding movement radially of said axis, said driven elements being disposed in a generally circular array, alternate ones of said driven elements including means for drivingly engaging an endless drive element, the remaining ones of said driven elements being in slidable contact with said endless drive element,
• c. cam means mounted for rotation about said axis and operatively engaging said driven elements for positioning said driven elements at selected ones of a plurality of radially spaced-apart positions in response to relative rotational movement between said driven elements and said cam means,
• d. detent means coupled between said driven elements and said cam means for restraining same against relative movement, and
• e. shift means for causing selected rotational movement between said driven element and said cam means to thereby alter the relative rotational positions thereof, the radial displacement of all said driven elements from said axis being generally equal for all relative positions of said driven elements and said cam means.
