Abstract
The over-running clutch pulley of a preferred embodiment of the invention includes a sheave member, a hub member located substantially concentrically within the sheave member, a spring member, and a stop surface, which cooperate to rotationally engage an input device and an output device. The sheave member preferably includes a sheave input section adapted to the engage the input device, and a sheave clutch section defining a sheave clutch surface. Similarly, the hub member preferably includes a hub output section adapted to engage the output device, and a hub clutch section defining a hub clutch surface. The stop surface functions to engage the spring member and to transfer some torque from the sheave member to the hub member during the acceleration of the sheave member in the first rotational direction relative the hub member.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
