DEFINITION

Classification: 474/83

Including mechanism for shifting belt axially on spaced pulleys with tapering drive face:

(under subclass 69) Subject matter including separate pulleys* mounted for rotation about axes spaced from each other, the belt*-driving face of at least one of the pulleys being inclined at a substantially constant angle of inclination relative to the pulley axis; and further including a device for moving the belt in a direction parallel to the longitudinal extent of the axis of each pulley.

SEE OR SEARCH THIS CLASS, SUBCLASS:

3, 6, 80+, 102+, and 122+, for other structure involving lateral shift of a belt such as for reversing the direction of rotation of a load driving member, for causing a change in speed ratio, for removing a belt from a pulley or for correcting belt training deviation.
