Abstract
A clutch arrangement for a power tool having a multi-speed transmission. The clutch arrangement includes a clutch member and a follower member. The clutch member is coupled to a member of the transmission that is proximate the torsional input of the transmission and which must be in a non-rotating position to permit the transmission to perform a torque multiplication operation. The follower member is biased into engagement with the clutch member to inhibit relative rotation therebetween. As the clutch member and the transmission member are coupled to one another, the transmission is able to perform a torque multiplication operation. When, however, the torsion that is exerted onto the clutch member is sufficient to overcome the frictional engagement between the follower and clutch members, the clutch member, and the transmission member, rotate, thereby inhibiting the capability of the transmission to continue to perform the torque multiplication operation.
