DEFINITION

Classification: 464/37

Torque transmitted via resiliently biased positive drive connection (e.g., cam and follower):

(under subclass 30) Subject matter wherein one of said input or output members, or an intermediate member, includes a contoured face; and the other of said input or output members, or an intermediate member, includes or carries a device resiliently biased into engagement with the contoured face to provide a positive drive connection for transmitting torque between the input and output members by contact of the device with an abutment forming a part of the contoured face, and wherein the shape of the abutment is such as to force the device against its resilient bias in a direction away from the abutment to permit said relative rotation when said resistance to rotation exceeds said predetermined value.
